ABSTRACT:
A driving mechanism for a vehicle wheel includes a housing and piston-cylinder assemblies pivoted to side plates of the housing. Each assembly communicates with hydraulic fluid under pressure and a reciprocating piston rod of each assembly drives a pinion through a surrounding eccentric and driving ring when the assembly is rocked about its pivot connection. The assemblies with corresponding pinions are located around and in mesh with the outer periphery of a central pinion that is fixed to an output shaft to rotate the wheel. As each assembly rocks, a sliding valve within a control valve housing opens and closes return and inlet fluid ducts. An anchorage links each sliding valve to the housing for the mechanism. The latter housing affords the connection between the wheel and the vehicle frame and includes two spaced apart plates with strips between the plates that leave upper and lower blocks. The blocks hold king pins for steering the wheels and comprise duct means for inlet and return ducts to each assembly.
