It mainly consists of three parts: the steering control mechanism, the steering gear, and the steering transmission mechanism. It has a significant impact on the vehicle's handling stability, driving safety, and driving comfort. The steering arm (usually referring to the steering rocker arm) is part of the steering transmission mechanism. Its function is to transmit the force and motion output by the steering gear to the steering straight-pull shaft and adjust the angle when necessary to meet different steering requirements.

The steering elbow is generally installed by directly plugging the mounting end into the cavity, and lacks a sealing function. After the steering sensor harness is assembled in the automobile steering device, it is prone to oxidation and aging after long-term use due to the complex and harsh environment, which affects the normal transmission of the signal. Therefore, the utility model proposes a sensor harness sealing structure to solve the problems existing in the prior art. Utility Model Content
