Abstract

The invention discloses an integrally combined differential lock, which comprises a shell, a shifting fork shaft and a piston connected with the shifting fork shaft, wherein the shell is provided with a cavity corresponding to the piston position, the inner wall of the cavity is provided with a protective device, the piston is in matched connection with the protective device, the external port of the cavity is provided with a sealing cover, and the sealing cover is hermetically connected with the shell; the sealing cover, the cavity and the piston form a closed cylinder mechanism; and the sealing cover is provided with an air intake communicated with the cavity in the closed cylinder mechanism. A working cylinder structure is canceled, a reduced shell or a gap bridge box body and a sleeve form a closed cylinder body, meanwhile, the piston and the shifting fork shaft are combined into one to form an integrated shifting fork shaft, and the integrated shifting fork shaft is combined with a cylinder cover to form a differential lock structure. The work efficiency of the differential lock is improved, the structure of parts is simplified, the product number is reduced, the improvement on production efficiency is convenient, and after-sale service is convenient.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an integrated combined differential lock for locking an auto differential. Background technique [0002] The differential plays the role of a transfer differential when the car is in different steering, different road conditions, or when the driving wheels are at different speeds and torque imbalances. When the car turns, the distance traveled by the wheels on both sides is not equal. When the differential is not in effect, the drive wheels on both sides run at the same speed, in order to meet the requirement that the travel of the outer wheels is greater than that of the inner wheels when the car turns. The inner wheels have a tendency to slip, while the outer wheels have a tendency to slip. The road surface will act on a forward additional resistance to the wheel of slipping like this, and the additional resistance acting on the pulley wheel is backward. At this time, the...
