ABSTRACT:
An all-terrain vehicle is provided with eight wheels on four equidistant axles all driven from a single engine via two transfer boxes and differential gear units on each axle. The axles are fully floating beam axles on long travel coil springs and controlled by radius arms and Panhard rods. The radius arms may be parallel to and co-extensive with the respective propeller shafts coupling the differential gears to the transfer boxes and the connections between the propeller shafts and the transfer box outputs include torsional vibration dampers. The couplings at the ends of each propeller shaft to the transfer box and the differential gear unit comprise respective universal joints, and the yokes of the universal joints at opposite ends of the propeller shaft are set to be rotationally out of phase, with the driven yoke lagging the driving yoke. A dual circuit braking system with a deceleration sensing valve can be provided to limit the hydraulic pressure to the front wheel brakes.
