Automobile kingpin caster angle measurement device

Abstract

The invention discloses an automobile kingpin caster angle measurement device. The device includes a mounting plate, an upper ball pin and a lower ball pin. The upper ball pin and the lower ball pin are respectively mounted at one side of an upper part and one side of a lower part of the mounting plate. The upper ball pin and the lower ball pin are mounted at the same side of the mounting plate. Ameasurement mechanism is mounted at one side of the mounting plate between the upper ball pin and the lower ball pin. Data spreading / display can be carried out in real time during measurement throughan inclinometer, and measured data are more diverse and accurate. The device is more efficient than a method of measuring a kingpin caster angle by four-wheel positioning, and saves adjustment time.Four-wheel positioning needs multiple times of wheel rotation, needs wheel adjustment before rotation, wastes time and effort, and is lower in work efficiency. The inclinometer is easy to mount duringuse, adjustment is fast during mounting, a measurement result is more accurate and efficient, and cost of measurement is saved.

Description

technical field [0001] The invention relates to a measuring device, in particular to an automobile kingpin caster angle measuring device, which belongs to the application field of the automobile kingpin caster angle measurement. Background technique [0002] The angle between the axis of the kingpin and the vertical line on the ground in the longitudinal plane of the car is the caster angle of the kingpin. Its function is to maintain the stability of the car when driving in a straight line and to promote the automatic return of the front wheels after turning. It is a rigorous process in the car manufacturing process. The calculated angle to accommodate the car's travel. [0003] The kingpin caster angle is usually measured by the four-wheel alignment method, but the existing four-wheel alignment method to measure the kingpin caster angle still has certain deficiencies. At present, in the process of adjusting the four-wheel alignment of the existing automobile main engine fa...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for measuring the caster angle of an automobile, which can solve the problem that in the process of adjusting the four-wheel alignment of the existing automobile main engine factory, the measurement of the caster angle generally uses the front wheel to turn twice. Method Calculate the kingpin caster angle value through computer calculation. During the process of adjusting the kingpin caster angle, the data cannot be displayed in real time. You can only turn to the steering measurement again after adjustment, which increases the adjustment man-hours and workload, which is not conducive to the improvement of production efficiency.
