Problems solved by technology

[0006] This measurement method takes the wheel of a combine harvester as an example. Two laser sensors are used to measure the position of two points on the wheel tire, and the two points are required to be symmetrical about the hub center of the wheel. The wheel is always fixed during the measu...

Abstract

The invention relates to an automotive toe-in measuring device and an automotive toe-in measuring method using the same. The automotive toe-in measuring device comprises a base; a vertical arm capable of telescoping in the vertical direction is arranged on the base; a cross arm capable of telescoping in the front-rear direction is connected to the vertical arm; the cross arm is provided with an aligning device used for aligning the center of a wheel hub; the cross arm is provided with a graduation ruler capable of extending in the left-right direction and telescoping in the left-right direction; the graduation ruler is provided with a measuring head used for positioning and measuring a fixed point. The invention aims to solve the technical problem that the exiting wheel tire worn affects measuring precision.

Description

technical field [0001] The invention relates to an automobile toe-in measurement device and an automobile toe-in measurement method using the device. Background technique [0002] The toe-in of the car chassis needs to be adjusted. After the car has been running for a period of time, it is easy to cause the toe-in of the steering wheel to be out of tolerance, which will lead to vehicle deviation, high-speed shimmy, high-speed drifting, and abnormal tire wear. At present, in the maintenance process of automobile steering axles, many manufacturers use professional four-wheel alignment measuring equipment to adjust the toe-in. However, this type of equipment is not only expensive but also cumbersome to operate, and has not been popularized and accepted in regional service stations and repair stations. effective application. [0003] In order to solve the above problems, simple toe-in measurement tools are often used in the prior art, such as figure 1 As shown, the toe measuri...
