Abstract

An embodiment of the present invention discloses a bearing assembly of a vehicle steering device, which includes: a bearing including an inner ring fastened to a rack, an outer ring disposed outside the inner ring, and a bearing disposed between the inner ring and the outer ring a ball between the inner ring and the outer ring, and a sealing member arranged between the inner ring and the outer ring; the elastic clip includes a main body part that is closely attached to the outer peripheral surface of the outer ring The fastening portion bent in the side surface direction of the outer ring extends from the corresponding end portion of the fastening portion and protrudes toward the side surface direction of the outer ring to form an elastic portion having a curvature.

Description

technical field [0001] The present invention relates to a vehicle steering device, and more specifically, to a bearing assembly included in the vehicle steering device. Background technique [0002] In recent years, an electric power steering apparatus using an electric motor has gradually spread from a hydraulic power steering apparatus (Hydraulic Power Steering Apparatus) utilizing hydraulic pressure of a hydraulic pump to a power assisted steering apparatus of a vehicle. [0003] A typical electric power steering device like this includes a steering device connected from a steering wheel to wheels on both sides and an auxiliary power device that provides steering assist power to the steering device. [0004] The auxiliary power unit includes: a torque sensor that senses the steering torque applied by the driver to the steering wheel and outputs an electronic signal proportional to the sensed steering torque; an electronic control unit (ECU: Electronic Control Unit) based ...
