Abstract

The invention discloses a differential lock assembly, which consists of a shifting fork, a shifting fork shaft, an air cylinder and a piston. A small end of the shifting fork shaft is provided with an O-shaped sealing ring, passes through the piston, is locked by a small hexangular groove-shaped flat nut, and is fixed by an elastic cylindrical pin; the shifting fork shaft in an inner cavity of the piston is provided with two return springs; the inside of a cylindrical groove at the right end of the piston is provided with a leather cup; the left end of the shifting fork shaft passes through a base and is sleeved with the shifting fork; the air cylinder sleeves the piston in the inner cavity; and a connecting position of the cylindrical surface at the left end of the air cylinder and the base is provided with an O-shaped sealing ring. When performing gas tightness check under 0.35-0.8MPa, the differential lock assembly has no gas leakage; the shifting fork has flexible action and return, no blockage phenomenon, and working effective stroke more than 20; and the differential lock assembly meets various technical indexes, and ensures product quality.

Description

Technical field: [0001] The invention relates to auto parts, in particular to a differential lock assembly of auto parts. Background technique: [0002] The current differential lock assembly is checked for air tightness at 0.35-0.8MPa, and there is an air leakage phenomenon, and the movement and return of the shift fork are not flexible, and the phenomenon of stagnation often occurs. The effective stroke of the shift fork is less than 20. It has seriously affected the product quality and brought great economic losses to the enterprise. Invention content: [0003] The purpose of the present invention is to provide a differential lock assembly, which can well overcome the problems existing in the current differential lock assembly. The object of the present invention is achieved in this way. A differential lock assembly is composed of a shift fork, a base, a shift fork shaft, a cylinder, and a piston. It is characterized in that: the small end of the shift fork shaft is p...
