Description

Technical Field

[0001] The utility model relates to the field of automobile components, in particular to a steering column. Background Art

[0002] The steering column, also known as the steering column, is a key component that connects the steering wheel and the steering gear. Its main function is to control the direction of the car, transmit torque, and absorb the energy of the car when it hits the car. It is mainly composed of an upper column tube, a lower column tube, an upper steering shaft, a lower steering shaft, an upper mounting bracket, and a lower mounting bracket. These components work together to ensure that the rotation of the steering wheel can be accurately transmitted to the steering gear, thereby controlling the direction of the car. In order to meet the driver's comfort requirements, the up and down and front and back directions of the steering column can be adjusted. However, the installation process of the existing automobile steering column and steering wheel is relatively cumbersome, and it often takes a long time for the maintenance technician to disassemble and install, thereby reducing the installation efficiency of the steering column. For this reason, we propose a steering column. Utility Model Content
