Would like to ask members for their input on a future project I'm planning - to fit rear wheel steer to my modified/Class1 trials car.
The intended conversion will have a Defender front axle tube with the diff mounted in the opposite side so the steering arms on the hubs are facing to the rear as they would if on the front. The axle on the rear is currently fitted with a pegged diff running with Ashcroft h/duty 4.11 crownwheel/pinion set, ARB locker and ashcroft shafts. I am expecting to run a full hydrostatic independant steering system with a joystick control and an electrohydraulic self centering system operated by simple on off button - hopefully mounted on the steering wheel spinner/knob. The theory being that once the obstacle has been negotiated full concentratin can be applied to diff locks or fiddle brakes whilst the steering hand centers the rear wheels without having to lean out and do it by eye.
I should also say that I am hoping to power the hydraulics with an electrical pump pack - does any body have any experience of accumulators, i.e. so the hydraulic pump can build up the pressure and store it so the pump can cut in & out?
That is my basic plan and I open it up to the forum to pick it to pieces - nicely please!
Cheers - Pete
