Embodiment 1

[0050] see Figure 1-Figure 13 , a vehicle caster angle and kingpin inclination measuring device, comprising a kingpin caster angle measuring device and a kingpin inclination measuring device, which includes a fixed part A, an adjusting part B (kingpin caster angle adjusting part, kingpin inclination angle adjustment part) and measuring part C, the fixed part A is used to clamp the tire; the adjusting part B is installed on the fixed part A, and the adjusting part B is used to adjust the direction and angle of the measuring part C, and adjust the measuring part C The angle of the X-Z plane and Y-Z plane is to ensure that the measuring part C is on a suitable measuring plane; the measuring part C is installed on the adjusting part B to measure the caster angle and the inclination angle of the kingpin of the vehicle.

[0051] Because the supports of the kingpin caster angle measuring device and the kingpin inclination measuring device are different (the support plate of the king...

Embodiment 2

[0057] A kind of vehicle kingpin caster angle and kingpin inclination angle measuring method, the method adopts above-mentioned vehicle kingpin caster angle and kingpin inclination angle measuring device to carry out vehicle kingpin caster angle and kingpin inclination angle measurement; comprise the following steps:

[0058] When measuring the kingpin caster angle, clamp the tire through the fixing part, and fix the vehicle kingpin caster angle and kingpin inclination angle measuring device on the tire; through the adjustment of the adjustment part, the measuring part can be kept at a suitable height and proper measurement on the surface, and adjust the slide rail of the measurement part to the level; open the measuring arm of the digital display angle ruler, move the digital display angle ruler along the slide rail, and make the infrared one-line lasers produced by the infrared one-line laser irradiate respectively At the central position of the shock absorber at the fixed en...

Abstract

The invention discloses a device for measuring a kingpin caster angle and a kingpin inclination angle of a vehicle. The device comprises a fixing part, an adjusting part and a measuring part, the fixing part is used for clamping a tire; the adjusting part is arranged on the fixing part and is used for adjusting the angles of the measuring part on the X-Z surface and the Y-Z surface, so that the measuring part is kept horizontal; and the measuring part is arranged on the adjusting part and is used for measuring the kingpin caster angle and the kingpin inclination angle of the vehicle. The invention further discloses a method for measuring the kingpin caster angle and the kingpin inclination angle of the vehicle. The kingpin caster angle and the kingpin inclination angle of the vehicle can be quickly and conveniently measured, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to a method and a measuring device for measuring caster angle and inclination angle of a kingpin of a vehicle. Background technique [0002] The kingpin of the car is the center of gyration when the steering wheel turns on the traditional car. The false kingpin is a straight line from the center position of the fixed shock absorber on the vehicle body to the center of the ball pin at the lower end of the steering knuckle. The positioning parameters of the kingpin include the caster angle and the inclination angle of the kingpin. Its function is to make the front wheels automatically return to the straight line when the vehicle is running, to keep the straight line, and to avoid the vehicle's straight line deviation, front wheel shimmy, and steering wheel shaking. happened. [0003] At present, four-wheel aligners are mainly used to measure the caster angle and inclinat...
