bill van snorkle Posted October 8, 2013 Author Share Posted October 8, 2013 As long as it doesnt end up being as heavy as a Champ Yes in most respects the Champ was an over complex, over weight, and not particularly capable pile of pigeon droppings. The 5 spd gearbox, if the reversing box was integrated with it, would be interesting to graft on to the front of a LandRover transfercase for 10 forward and reverse gears though.

Jamie_grieve Posted October 9, 2013 Share Posted October 9, 2013 It's late and I'm thinking out my ass a bit but how easily could a planetary gearset be arranged where the clutch normally lives, maybe with a hollow sun gear as a quill shaft connected to the clutch plate driving a set of planetaries living in the bellhousing finally driving another hollow gear going through the quill shaft and splined to the gearbox where the middle of the clutch plate would normally be. This bit might have to double up as a release bearing too. The clearances on the spur gears would maybe want to be considered due to the relative movements of everything concerned This could give an alternative set of ratios and be made in such a fashion to be bolted in and out of a standard transmission maybe with just an alternative clutch plate and little modification to the bellhousing. Does any of that make sense to anyone not sleeping? Quote Link to comment Share on other sites More sharing options...

Does any of that make sense to anyone not sleeping? I don't see any reason why that couldn't work Jaime. Because that unit would only ever see engine torque, as opposed to engine torque multiplied by main gearbox ratios, the planetaries would not need to be as substantial as those on a unit fitted after the gearbox. It may be even possible to fit it within the wasted 4 or so inches of bell housing length of say an LT95 where the FC101 bell housing is that much shorter than on the RRC/110/Stage One V8's for example. Probably quite doable with the unused planetaries of the GKN overdrive I pinched the bits off for the crawler box adaption. Thanks a lot Jaime. your post will give me another couple of sleepless nights thinking of how to make it work.Lol. Quote Link to comment Share on other sites More sharing options...

Jamie_grieve Posted October 11, 2013 Share Posted October 11, 2013 Summary: It comprises a transmission system (3,5,6,12,20) capable of adopting at least a first position, in which establishes a first relationship of trans- mission between an input shaft and an output shaft, and a second position in which establishes a se- second transmission ratio between these axes, is inserted between the output shaft of the motor and the shaft entrance to the gearbox, and further comprises clutch means (15,16) adapted to allow system over said first transmission position to said second position and vice versa, and I- control means (30) of said clutch means (15,16). Lets double the number of gears, and is applicable ble to vehicles series so fast and easy. DESCRIPTION Particularly speed multiplier for vehicles. The present invention relates to a multi- speed multiplier, particularly for vehicles, comprising a transmission system mission capable of adopting at least two positions tions, a first position in which he states a first transmission ratio between a shaft input and an output shaft and a second po- sition in which establishing a second relationship transmission between these axes. This device allows you to double the number gears, and is applicable to vehicles series fast and simple way. BACKGROUND OF THE INVENTION Mechanical devices are known, more or less We sophisticated applied to changing sea- chas of a vehicle to increase the number gear, is well known, for example, "Overdrive", which is mounted to the gearbox output changes and provides a new combination Gear leading to May 1 to ¯ or long- permarcha. These devices have the advantage of adding a new transmission ratio between the axis of motor and gearbox output shaft but have several drawbacks that limit their application. First, the known mechanisms pose a number of problems arising from their mounting the gearbox output. They tend to be vo- light, and can not be installed in any vehicle, in addition, allow the mayorıaunicamente ten to add an overdrive. The utility model U 201763 proposed a multiplier mounted outlet box changes, which doubled the number of marches vehicle and which is satisfactory in some applications tions, however, now been found that can improve the performance and the compatibility ity of known devices. Description of the invention The aim of the present invention is to propose ner multiplier speeds not pre- present the aforesaid drawbacks, which may apply Carse any vehicle marches doubling the same, and installation is fast and sen- cilla. In accordance with this objective, the multiplier speed according to the invention is character- ized by the fact that is inserted between the shaft engine output and the input shaft of the box changes of a vehicle, and further comprises clutch means adapted to allow transmission system over said first position to said second position and vice versa, and said control means clutch means. The device offers a number of advantages im- portant. First, to duplicate all gears of the gearbox, including re- conductive in the case of 4x4 vehicles. This lead to a much better poten- tion engine, acquiring greater flexibility When choosing a relationship. Eg For overdrive, the device allows 30% increase to top speed, re- ducing also the regime. Is therefore reduces the emission of greenhouse gases, and increases the life of the engine and its components tees. Also helps reduce consumption fuel. Thanks to its location, can be installed easily and quickly as a separate kit tooth, between the engine and the gearbox any vehicle. This location also makes compatible with all types of gear boxes, re- conductive, differential locks, etc.., making the Maximum performance thereof. Finally, note that deletes all Typical problems of multi-joint mount multipliers such as "overdrive" at the end of the gearbox. Preferably, in the first position the ve- speed of rotation of the shaft of the gearbox is higher than the motor shaft (upshift) and in the second position the speed of rotation both axes is the same (low gear). The multiplier effect is thus adding a longest running each of the marches of gearbox. In a preferred embodiment of the invention, the transmission system comprises a corona driven in rotation from the motor shaft, a planetarium that is coupled in rotation with the axis of the gearbox, and at least one satellite meshing with said crown and said planetarium, said satellite mounted on a swivel. Advantageously, the clutch means com- comprise a first clutch when this em- energetic blocks in rotation the turntable, so that the rotation of the crown is transmitted deeste the satellite and the planetarium, and a second when this clutch clutch transmits the rotation of the swivel to the planetarium with interposition of a transmission element; Control means the first clutch clutching desembragan gue and second to obtain di- said first position of the transmission system, and desembragan clutching the first clutch and the second in order to obtain said second position transmission system. This configuration has the advantage of per- allows moving from one position to another, ie long or short march back without disconnect tar engine change (without pressing the pedal clutch of the vehicle) so that the ma- maneuver can be performed very quickly, without slow down and without down torque to zero, with the consequent advantages, for example, under conditions of competition. Also advantageously, the clutches are panied multi-plate clutch in oil bath. Thus, the clutch acts with more sua- activity and is more durable and has a perfor- nes far superior to standard clutch. In one embodiment, the first clutch is disks coupled in rotation with the support satellite rotating and fixed disks, and follow- second clutch is coupled disks rotation with said support and engagement disks two with said transmission. According to a particularly advantage of the invention, said satellite is a eccentric wheel mounted only on the co- rona and planetarium, which has a toothed engaging the outer crown and a den- internal state that meshes with the planetary man- taking the wheel meshed with crown and warming by two diametrically opposed areas. This new configuration of the satellite man- has the size of the multiplier at a level adpatarlo allowing virtually any vehicle in substitution by standard clutch. According to one aspect of the invention, the means control valve comprising a regulatory and two cylinders that control solenoid Hydraulic, each of which drives one of clutches. Preferably, said check valve and said solenoid are governed through a knob in the Cabin to pass up short to long and back up, and through the vehicle clutch pedal to disengage the two clutches simultaneously. Also preferably, the regulating valve dora has means to cushion the manio- bra of the two clutches engaged. Thereby avoiding an abrupt clutch of the discs when the driver releases the pedal clutch. BRIEF DESCRIPTION OF THE DRAWINGS For more understanding of what has been ex- position is accompanying drawings in which is- schematically and solely by way of example not limited to, show a practical case of realization. In said drawings, Figure 1 is a schematic sectional view longitudinal speed multiplier ties of the present invention; Figures 2a, 2b are schematic longitudinal section of a valve regulated troller used in multiplier invention in two operating positions tion, and Figures 3 and 4 are schematic cross section of two embodiments al- alternatives gears of multiply- dor. Description of a preferred embodiment Figure 1 shows schematically the ele- Key elements of the multiplier according to the invention. The device is mounted between the engine and the gearbox, the clutch replacing standard of the vehicle and the driver has a controller for acting on the device. The device causes, at the pleasure of driving engine, a variation between the speed of shaft-sa engine output and input speed cam- Bio: As a result, each change relationship (Each gear of the vehicle) is actually du- complicated in a low gear, which coincides with the Serial vehicle because the output shaft engine and input shaft rotate at the change same speed, and a high gear when the driver operates the multiplier and the device introduces a non-unity transmission ratio between the engine output shaft and the input shaft of change. A drive pulley coupled to the shaft 2 is engine output, and is input multiplier, while a planetary three con- tituye and the multiplier output is coupled through a splined to the input shaft 4 (not shown) of the vehicle gearbox. The drive plate 2 is coupled to a co- ring gear 5, which engages with one satellite 6 constituted as described below with reference to Figure 3, a pre-wheel sents both an external toothing 8 as a den- internal state 9. The satellite toothing 9 6 turn meshes with a toothing 10 of the planetary Three. As best seen in the view of Figure 3, the eccentric 6 is mounted satellite respect to the ring gear and the planetary May 3 and always remaining wheel meshing entreestos either swim in two diametrically opposed. The satellite 6 is mounted on a support 12 with interposition of suitable bearings 13, the also support 12 can rotate, driven by the rotation of the satellite in June. The device also has two sets clutch plates are denoted with the reference ing 15 and 16, respectively. Half of the disks of each set, 15a and 16a, respectively, mind, are integral in rotation with the support Satellite 12, as shown in Figure 1. The other half of the clutch discs 15 (Disks 15b) are integral to the housing of the device positive (not shown), and are therefore permanently fixed. Meanwhile, the other mi- 16b tad clutch discs 16 are requested DARIOS a transmission element 20 that is coupled with the planetary rotation through three of a key 21 or striatum. In the following description, the clutches 15 and 16 are called "long clutch" and "em- clutch of short "respectively. This so- tion is that, for each gear of vehicle gearbox, when em- panty disk set the planetarium turns 16 the same speed as the motor shaft, so that the relationship is the corresponding transmision to the vehicle gearbox (low gear), whereas when engaging the set of 15 the planetary disc rotates at a speed faster top, and the transmission ratio is higher (Long March). When the clutch plates clutching of short 16, the rotation of the crown 5 is trans- 6 and allows the satellite to its support deeste 12 which 16 through clutch drag element 20.This transmission, in turn, drives in ro- planetarium Tacion 3 after the union by cha- vein 21. The characteristics of this chain ci- nematic are such that the rotation speed planetarium is like the engine shaft. In contrast, when clutching disks long clutch 15, the transmission is from the crown 5 to 6 and deeste satellite direct- Planetary mind to 3, since the bracket 12 satellite is locked in rotation by the em- clutch 15 (as mentioned, the discs 15b deeste are fixed to the housing). This transmission introduces a variation in the speed of the pla- Monetary previous case (Long March). The clutch discs 15 and 16 are panied in oil bath for more performance smooth and to be more durable. Speed multiplier described com- also comprises a hydraulic circuit pump (not shown) for two cylinders 25,26 actuation of the clutches 15 and 16, respectively, tively, and check valve 30, repre- Tada schematically in Figures 2a, 2b. The hydraulic cylinder 25 is fixedly mounted multiplier housing while the ci- cylinder 26 is secured to the transmission element 20 and rotates therewith. The check valve 30 shown in FIG- Figure 2 is designed to allow control of the clutches 15 and 16 to go from short to long or vice versa, via a button or a drive Similarly, and also when you want to disengage to change gear, pedal through vehicle clutch. For this, the valve 30 comprises a housing house 31 in which are formed a series of ga- Lérias of oil pressure and return connections and are in communication with a housing axial 32 which slides a rod 33. Between the rod 33 and the housing 32 is interposed a slider 34 which is externally one plurality of recesses to allow, depending on their position along the housing 31, open selectively tively the passage between the different galleries. Around the stem 33 are mounted one valve spring 35 and a spring dispenser 36 whose mission is to give more or less pressure. On- spring is mounted between two floating one Spanish- ciador 37, which acts as a stop to prevent com- Excessive spring pressure dispenser 36. A shutter 38 closes the front of the housing tion 32. In the housing 31 is further formed a CA- cavity 39 adapted to accommodate a solenoid conventional (not shown) which controls the Oil supply to the cylinders 25 and 26. Figure 2a corresponds to a normal position poorly functioning, ie, a position of valve in which one of the cylinders 25 or 26 maintains the corresponding clutch engaged 15 or 16 (depending on the position of said conventional solenoid), and the torque is transmitted to the gearbox. Depending on which of the clutches 15 and 16 is attached, the be long or short march. To change gears, for example 3 to ¯ to 4 to ¯ , The driver presses the clutch pedal gue, which causes thanks to the configuration the check valve 30, the drive if- simultaneous of the two cylinders 25 and 26 and the unem- clutch of the two sets of disks 15 and 16, of so that the gearbox is disconnected Tada engine, as in the case of a clutch traditional, and the driver can change sea- cha. The rod 30 is coupled at its end free the vehicle clutch pedal: when the driver depresses the pedal, the rod 30 is shifted from the position of Figure 2a to the Figure 2b position, dragging the slide 34, thanks to the presence of a plug 40 which is threaded to the end of the slider 34. This movement of the slider opens the passage oil between some housing Galleries 31 so that the two hydraulic cylinders 25 and 26 are actuated simultaneously to release rar disks of the two clutches 15 and 16: in Consequently, the drive shaft is disengaged from gearbox, and the driver can change gears. When the driver has changed sea- cha and stops the clutch, this re- its initial position by the action of a corresponding tooth spring (not shown), dragging with- I keep the rod 33 back to the position of Figure 2a, however, thanks to the provision Springs 35 and 36, this movement is made gradually, so that coupling is avoided ing abrupt clutch discs between other. To move from one place to the corresponding short sponding high gear, the driver must sim- ply operation of a control, for example a button which may be located on the lever change: this drive through the check valve 30 and the conventional solenoid tion, change the position of the pistons of the ci- cylinders 25 and 26, so that clutch discs gue of short 16 are disengaged and discs Long clutch 15 are clutched, at which varies the speed of the planet and Consequently the output of the gearbox, passing a short march to the same gear long, or vice versa. Importantly, it is not necessary press the clutch pedal for this step of long or short to long to short: it has logically the advantages of allowing manio- bra faster and the torque does not drop to zero during the maneuver. Figure 3, as noted, represents cross section position and configuration of the Satellite 6: in this preferred embodiment, the satellite This consists of a double-toothed wheel 8 and 9, mounted eccentrically to go rolling between the crown and the planetarium March 5. This structure has a number of advantages: First, to limit the dimensions multiplier, and thanks to these small di- dimensions the device can stay without pro- replacing the conventional clutch problems of a vehicle, in addition, thanks to the diameter of satellite, engagement with the crown and Planetarium is carried out on a high number of teeth, ga- suring quiet operation and a minimum vibration. However, the transmission between the crown 5 to planetary 3 could be done with a plu- rality of satellites conventionally as shown in Figure 4: in this case are mounted Four satellites 6 around the circumference 3 planetarium, all coupled to a so- support 12 as described for the realization above. Another possibility is to perform the transmission in- between the drive pulley and the output shaft through a gear train, instead of a system crown, and planetary satellite in this case, one gear be mounted on the support Although herein is been described and shown an embodiment with- chalk device according to the present Page 6 1.

Snagger Posted October 16, 2013 Share Posted October 16, 2013 Hmmm... a bell housing mounted epicyclic overdrive with integrated clutches and solenoid operation that is fitted in place of the standard clutch system. I think that overdrive would have heat issues and would kill the crank shaft spigot bush in fairly quick order, but it's a nice idea otherwise - there's a lot of wasted space in the bell housing of the short stick LT77s and R380s, and maybe the automatics too (I have never seen the innards, so don't know how much of the void is taken up by the torque converter). It would be a tidy way of fitting an overdrive to a non-1.4 transfer box equipped vehicle, like RRCs and Discoverys, or fitting an overdrive while still having the rear PTO available on a Defender. It's the sort of thing I'd consider on my RR, given that it has an R380 and Borg Warner unit that is well geared for most use but undergeared for motorway cruising.

elbekko Posted October 16, 2013 Share Posted October 16, 2013 The bellhousing is pretty much filled with the TC. But it does show that it can be done, as the TC is technically an underdrive. May need something similar to the flex plate to make the crank bush live though. Quote Link to comment Share on other sites More sharing options...
