摘要： Wheels of a dump truck are each provided with a travel assembly for transmitting an output of an electric motor to the wheel via a reduction gear unit. The travel assembly is provided with a cooling circuit for cooling lube oil. The cooling circuit has an oil cooler and a recovery oil passage for guiding lube oil from a side of the gear unit to the cooler. The recovery oil passage has an intra-spindle recovery line inserted on a side of an inner periphery of a spindle, a suction pipe extending from the recovery line to a space surrounded by the spindle, the wheel and two spindle-supporting bearings, and communication holes formed in the wheel to communicate the side of the reduction gear unit with the space.

摘要： A dump truck has a flange on an inner peripheral wall of a spindle. The flange arranges a support bearing for supporting a shaft. The spindle is formed of a chassis-side member and a reduction gear unit-side member joined together by welding. The chassis-side member is fixed on a chassis of the dump truck, and the reduction gear unit-side member is located closer to a side of the reduction gear unit than the chassis-side member. The reduction gear unit-side member is located on a side of an outer periphery of the shaft portion, where a distance to a coupling between the motor and shaft and a distance to a first sun gear between the reduction gear unit and shaft are equal to each other. On an inner peripheral wall of the reduction gear unit-side member, the flange is cast together with the reduction gear unit-side member.
