Automobile front axle steering angle infrared measuring apparatus

Abstract

The invention discloses an automobile front axle steering angle infrared measuring apparatus and belongs to the technical field of measuring instruments, and the apparatus is mainly used for solving the problem that good fixture and technology are unavailable to ensure the steering angle adjustment accuracy and stability in the existing automobile front axle assembly process. The automobile front axle steering angle infrared measuring apparatus is mainly characterized by comprising a base, a positioning device, an angle automatic display, an infrared receiving marker post and an infrared transmitting assembly, wherein the base is a rectangular base; a convex edge is arranged on one side of the lower surface of the base; the infrared receiving marker post is fixed on the upper surface of the base; the infrared transmitting assembly is mounted on the infrared receiving marker post; the angle automatic display is mounted on the base and connected with the infrared receiving marker post; and the positioning device is arranged at the lower part of the base. The automobile front axle steering angle infrared measuring apparatus disclosed by the invention can be used for solving the problems that the traditional front axle steering angle adjustment technology and method are unscientific and are strong in limitation and the like, has the characteristics of simplicity and convenience in operation, accuracy in measurement and wide application range, and is mainly applied to the steering angle adjustment and measurement in the automobile front axle assembly process.

Description

Technical field [0001] The invention belongs to the technical field of measuring instruments. Specifically, it relates to an infrared measuring instrument for the steering angle of the front axle of an automobile for adjusting and measuring the steering angle during the assembly process of the automobile front axle. Background technique [0002] The front axle of the automobile is an important part of the driving system. It is connected to the frame through the suspension. Both ends are equipped with automobile wheels to support and transmit various forces between the wheels and the frame. Realize the steering of the car. The steering angle is the angle at which the left and right wheels turn to the extreme position when the front axle of the car turns to the extreme position when the car is turning. It affects the stability and comfort of the car during driving. If the steering angle is adjusted too large, the lateral slippage between the tire and the ground will be increased ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the assembly process of the front axle of the automobile, there is no good tooling and process to ensure the accuracy and stability of the steering angle adjustment. The actual adjustment is mainly the following two methods: 1. Special tooling and fixture, this measurement method is very accurate for the front axle The manufacturing precision of shaft parts and other parts is high, and the measurement for a single variety cannot adapt to the adjustment of the steering angle of the front axle of multi-variety automobiles; 2. Use the universal angle ruler to contact one side of the universal angle ruler with the end face of the steering knuckle, and calibrate the angle with human eyes The parallelism between the other side of the ruler and the axis of the front axle. In this method, human factors and experience are more important, and the error is large.

[0004] The above two adjustment methods are increasingly unsuitable for the current increasing quality requirements for axle assembly and vehicle quality, so it is necessary to seek high-precision, high-efficiency and easy-to-operate measuring instruments
