Abstract

The present disclosure provides an automobile reducer including a worm shaft bearing coupled to an end of a worm shaft meshing with a worm wheel, the end lying opposite a portion of the worm shaft coupled to a motor shaft; a bush coupled to an outer peripheral surface of the worm shaft bearing, the bush having an incision formed by incising one side of the bush; a damper coupled to an outer peripheral surface of the bush inside a housing so as to force the bush against the worm shaft bearing and to elastically support between the housing and the worm shaft bearing; and a clearance compensation mechanism penetrating the damper and pressurizing the bush towards the worm wheel. The automobile reducer can accurately assist the driver's steering wheel manipulation.

Description

technical field [0001] The present invention relates to the field of automobile speed reducer, especially relates to a kind of automobile speed reducer, which can correct the excessive gap or too small gap caused by the error (error) related to manufacturing or assembling a casing and a worm gear shaft bearing And to compensate for excessive backlash associated with a worm shaft due to worm gear wear. The vehicle reducer is capable of compensating for an excessively small backlash associated with a worm shaft caused by the moisture-absorbing expansion of the worm wheel. The automobile speed reducer can alleviate the resistance caused by the sudden rotation or the change of the rotation direction of the worm wheel and with regard to the worm shaft of the worm wheel, so that the automobile speed reducer can accurately assist the driver to operate steering wheel. Background technique [0002] figure 1 It is a perspective view of a traditional automobile reducer. Such as fi...
