REDUCER FOR VEHICLE

摘要

Disclosed is a reducer of a vehicle. Size and weight of the reducer can be reduced by removing a pivot bearing and a damping coupler which are expensive and used for supporting a movement of a worm shaft and for buffering an impact applied to the worm shaft in a conventional reducer, thereby saving a manufacturing cost.

主权项

1. A reducer for a vehicle, comprising:
a motor housing in which a rotation supporting member is movably coupled to a coupling hole and supported by the motor housing, the rotation supporting member supporting one end, which is connected to a worm shaft, of both ends of a motor shaft coupled to the worm shaft which is tooth-engaged with a worm wheel; a gear housing which encloses the worm wheel and the worm shaft and is coupled to the motor housing; an elastic member interposed between an outer peripheral surface of the rotation supporting member and an inner peripheral surface of the coupling hole; an elastic supporting body which is disposed in the coupling hole and buffers an axial movement of the rotation supporting member; and a stopper member which is disposed in the coupling hole so as to prevent a separation of the elastic supporting body.
