Abstract: A skid steer vehicle has a chassis with four drive wheels suspended from the chassis that are damped by four damping cylinders. An electronic controller varies the damping of the cylinders in an automatic mode, based on certain operational parameters of the vehicle, and in a manual mode in response to operator selection of a desired degree of suspension damping.

Abstract: A skid steer vehicle has two drive motors that are connected by belts to spring-mounted front and rear wheels.

Abstract: A skid steer vehicle has a suspension that includes two bogies pivotally connected to the sides of the vehicle and extending fore-and-aft along each side of the vehicle. The bogies are pivotally connected to the vehicle in the middle and have a wheel mounted at each end. A hydraulic motor is coupled to each of the bogies and drives the two wheels on each bogie.

Abstract: A mechanical drive clutch is provided for mounting on a rotatable shaft. The drive clutch includes a drive gear having a plurality of gear teeth projecting therefrom. A sleeve is slidably mounted on the shaft for rotational movement therewith. The sleeve includes a plurality of gear engagement recesses therein of arcuate lengths greater than the predetermined arcuate lengths of the gear teeth. The sleeve is moveable between a first retracted position and a second engaged position wherein the gear teeth are received within corresponding gear engagement recesses in the sleeve in order to translate rotation of the drive gear to the shaft. A plurality of anti-backlash elements are provided to compensate for the difference in the arcuate lengths of gear teeth and their corresponding gear engagement recesses in the sleeve.
