초록

An improved drive assembly includes a gerotor-type hydraulic motor having a housing connected to a frame. An output member is rotatably mounted on a hollow spindle which is integrally formed with the motor housing. Operation of the motor rotates an input shaft which is disposed within the spindle and is connected with the output member through a gear arrangement. In order to tend to minimize the axial extent of the drive assembly, the gear arrangement is located inwardly of an outer end of the spindle. The gear arrangement includes a central or sun gear ...
