Half axle sleeve is an important part of automobile drive axle assembly. It is integrated with the drive axle housing to fix the axial relative position of the left and right drive wheels and support the mass of the frame and each component on it. When driving, it bears the road reaction force and torque transmitted by the wheels and transmits them to the frame through the suspension. How much do you know about the axle shaft sleeve? Follow the small series of rear axle half shaft sleeve to have a simple understanding and have a look!

The utility model relates to a disassembly device for an automobile half shaft sleeve, which comprises a support, a hydraulic cylinder, a large shell, a small shell, a small retaining ring and a large retaining ring. The hydraulic cylinder is located on the bracket. The hydraulic cylinder comprises a box body and a drive shaft, one end of the drive shaft is connected to one end of the small sleeve, and the other end of the small sleeve is connected to a small or large baffle ring. Greater than the inner diameter of the shaft sleeve. The inner diameter of the large shaft sleeve is not less than the outer diameter of the half shaft sleeve, and the large shaft sleeve is supported between the hydraulic cylinder and the axle box. The outer diameter of the small baffle ring shall not be greater than the outer diameter of the half shaft sleeve. The outer diameter of the large baffle ring is larger than that of the half shaft sleeve. The large baffle ring can prevent the small shaft sleeve from moving linearly away from the axle box along its axis. In addition, an annular positioning protrusion is arranged at the position where the box body contacts the drive shaft, and the outer diameter of the positioning protrusion is equal to the inner diameter of the large sleeve.
