ABSTRACT:
A vehicle with a hydraulic system including an engine with a hydraulic pump with at least one driven wheel which incorporates a separate driving mechanism having a hydraulic motor in communication with the hydraulic pump. This motor includes a housing with pistons which are cycled by hydraulic pressure applied through a switching arrangement which periodically opens pressure and return ducts as the wheel turns. A cam plate associated with the wheel shaft allows sensing rollers to move control elements of the duct control members as the wheel turns. The wheel shaft is connected to a crank arm and the pistons' lower rods are drivingly connected to the arm to turn same. Upper rods of the pistons are reciprocated in a tube in a conical housing which extends above the motor housing. The motor housing has an elongated upwardly extending pivot pin slideably held in a divided sleeve assembly, the lower portion of the sleeve assembly being affixed to the housing and the further portion of the sleeve assembly which is connected to the frame of the vehicle being caused by the weight of the frame to abut and adjoin the lower portion as supporting interfaces. The pivot pin received in the sleeve portions is non-rotatably received in the lower portion but movable in an axial direction so that upon the relative raising of the frame the pin is pulled from the lower portion whereby the frame is separated from the housing. The upper part of the pin extending out of the further portion of the sleeve assembly is connected to the steering mechanism of the vehicle.
