Clearance adjustment device and clearance adjustment method for differential lock

Abstract

The invention provides a clearance adjustment device for a differential lock. The clearance adjustment device is used for adjusting the clearance between a sliding engaging sleeve and a fixed engaging sleeve of the differential lock, and comprises a dial, a rotating sleeve and a pointer, wherein the dial is matched with the rotating sleeve; the rotating sleeve can be matched with a rotating shaft driving the sliding engaging sleeve to move and can rotate relative to the dial along with the rotation of the rotating shaft; the pointer is fixed on the rotating sleeve and can rotate relative to the dial along with the rotation of the rotating sleeve; and the rotating angle of the pointer can be displayed on the scale of the dial. The invention further provides a clearance adjustment method for the differential lock and a method for adjusting the clearance of the differential lock by utilizing the clearance adjustment device. Through the technical scheme provided by the invention, the clearance between the sliding engaging sleeve and the fixed engaging sleeve of the differential lock can meet the design requirement and be irrelevant to the stroke error of a cylinder, so that the differential lock can work normally.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to a differential lock gap adjustment device and a differential lock gap adjustment method, in particular to a differential lock gap adjustment method using the differential lock gap adjustment device. Background technique [0002] The working principle of the differential lock is: figure 1 As shown, the cylinder 5 drives a series of transmission mechanisms (including: the connecting rod 6, the rotating shaft 7, etc.), so that the sliding engagement sleeve 20 slides left and right on the half shaft. Under normal driving conditions, the sliding engagement sleeve 20 and the fixed engagement sleeve 30 are separated, and there is a certain gap 40 between the two sets of end faces, such as figure 2 As shown; under special road conditions, it is necessary to inflate the cylinder 5, and drive the sliding engagement sleeve 20 to engage with the fixed engagement sleeve 30 throu...

AI Technical Summary

Problems solved by technology

[0005] Using this method, the moving distance of the sliding engagement sleeve 20 depends on the stroke of the cylinder 5, that is, the gap 40 between it and the fixed engagement sleeve 30 is determined by the stroke of the cylinder 5, and the stroke of the cylinder 5 is due to processing, assembly, wear and other reasons. , is often quite different from the design value, and it is difficult to meet the design clearance requirement, thus affecting the normal operation of the differential lock
