Description
Model designed in 1996 to test the new infra-red remote-control set.
• front wheel drive
• four independent wheel working suspension
• steering
• electric motor
• differential
• remote control of forward/reverse and steering
The front suspension is Mc Pherson struts, the rear suspension is trailing arms, all with coil springs.
The steering is rack and pinion.
The remote control of steering is via a slipping rubber clutch driving, thus avoiding locking or damaging of the dedicated motor and/or mechanism when the wheels are steered to maximum position, and allowing the manual control of steering with the steering wheel.
The two track rods lengths and positions are so that the steering angle of each wheel remains constant when the suspension is moving in any position.
The differential is of the « narrow type », with powering external to the frame, and only one shaft (the driving shaft) ; the two independent output shafts are shifted and driven by the two free mounted 19-teeth planetary gears, thus allowing sliding of the driveshafts in the frame sides when suspension is moving (the 57 teeth gears slides along the planetary pinions).
The two universal joints in each driveshafts are fitted together so that they provide constant velocity for any suspension position, provided the wheels are not steered.
