Recently, Shiyan Dongsen Automobile Sealing Co., Ltd. “A semi-axle oil seal†has been granted a utility model patent certificate issued by the State Intellectual Property Office.
The main purpose of this patent is to improve the anti-eccentricity and pressure resistance, and to solve the problem of seal failure due to high temperature, high speed, and large eccentricity. At present, in the automotive industry, there is a keyway at the inner end of the vehicle's semi-shaft, and it meshes with the inner keyway of the axle gear to receive power from the differential. The outer end has a flange and is bolted to the hub to drive the wheels.
As can be seen from the use of the axles, the axles are subjected to a great deal of torque, forcing the wheels to rotate and allowing the car to travel. In the course of operation, the dynamic jitter generated is large, generally greater than 0.5mm. It is used for rear axle half shaft oil seals. Because the width of oil packaging space is limited, most of the oil seal factories have short waist lengths and waist sections in structural design. The phenomenon of irrational thickness and thickness of the lip can not satisfy the requirement of the semi-axle to have large dynamic runout.
The invention of the "Axle Shaft Oil Seal" of Dong Sen effectively solves the above problems, improves the anti-eccentricity of the semi-shaft oil seal, and quickly fills the gap due to large eccentricity. The oil seal has good followability and is effective. Sealed features.
