Automobile steering column assembly and clearance detecting device thereof

Abstract

The invention relates to an automobile steering column assembly and a clearance detecting device thereof. The automobile steering column assembly includes an upper steering shaft, a lower steering shaft, a sleeve, a steering wheel support and a mounting support, wherein the upper steer shaft and the lower steering shaft are connected through an upper universal joint; a low universal joint is connected to an end, away from the upper steering shaft, of the low steering shaft; the steering wheel support is connected to the upper steering shaft by a steering shaft limit spring; the sleeve is provided with a through hole allowing the steering shaft limiting spring to pass; the upper universal joint is detachably connected to the upper steering shaft by an elastic bolt; the low steering shaft and the lower universal joint are fixedly connected through a flange; and a connector for connecting the steering wheel is arranged at one end, away from the upper universal joint, of the upper steer shaft. The automobile steering column assembly and the clearance detecting device thereof can transmit the steering intention of the steer wheel to the steering gear effectively and accurately, and theclearance detecting device can more truly detect the clearance of the steering column assembly.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to an automobile steering column assembly and a gap detection device thereof. Background technique [0002] A series of devices used to change or maintain the driving or reversing direction of the car is called the car steering system. The function of the car steering system is to control the car's driving direction according to the driver's wishes. The parts of the steering system of the car are called security parts. The steering system and the braking system of the car are two systems that must be paid attention to in the safety of the car. When the car is running, it needs to change its driving direction according to the will of the driver. Car steering, as far as wheeled cars are concerned, the way to realize car steering is that the driver deflects the wheels (steering wheels) on the car steering axle (usually the front axle) relative to the longitudinal axis of the car through...

Problems solved by technology

With the continuous development of my country's automobile industry and the continuous improvement of automobile quality, people have higher and higher requirements for the quality of auto parts. As a part connecting the steering wheel and the steering gear, the quality of the steering column tube is particularly important. Therefore, Its inspection standards are also relatively strict. At present, there is no integrated detection equipment for the steering clearance detection of the steering column on the market. The invention patent application with the publication number "CN105222743A" publishes "a detection mechanism and the Its detection method", when the steering column is detected in its technical scheme, the steering column is in a straight line state, but after it is actually applied to the vehicle, the steering column is not in a straight line state, but in a broken line state, so the scheme There are limitations and cannot reflect the actual working conditions well, so it is necessary to design a stable and reliable steering column assembly and a device that can detect its steering clearance from multiple angles
