Abstract

The damping bush (10) for the steering mechanism of a vehicle of the present invention includes: a bearing (100) coupled to the same axis of the pinion shaft of the steering mechanism; a box (200) coupled to surround the outer peripheral surface of the bearing (100); a flange (300) provided inside the housing of the steering mechanism to support the bearing (100) and is coupled to the box (200).

Description

technical field [0001] The present invention relates to a damper bush for a steering mechanism of a vehicle, and more specifically, to a damper bush for a steering mechanism of a vehicle in which the coupling force between members of the damper bush and the rigidity of the damper bush are improved. Background technique [0002] Most cars are equipped with power assisted steering systems that generate support torque during steering and thereby reduce the steering torque applied by the driver to the steering column. [0003] A known power assisted steering system is based on a steering mechanism that converts the driving force of a hydraulic or electric driving device and transmits it to a steering column. [0004] This steering mechanism generally takes the form of a helical roller, formed by a helical gear or a worm gear. [0005] That is, the steering mechanism includes a housing 1 inside which a gear 2 and a pinion meshing with the gear 2 are supported. [0006] The pini...
