Abstract
A hydraulic drive system of a steerable wheel of a dump truck facilitates the attaching and detaching of a hydraulic motor and allows for a large hydraulic motor to be used. In the drive system, a wheel axle is rotatably supported within a receptacle seat supported on a yoke. The steerable wheel is rotatably mounted on the outer periphery of the receptacle seat. The steerable wheel and one end of the wheel axle are connected via a speed reducer. A motor casing 33 of a hydraulic motor is connected by bolts to the receptacle seat at an end of the seat remote from the steerable wheel so that the hydraulic motor can be attached to and detached from the receptacle seat by tightening and loosening the bolts.
