Axle shaft tube structure

Abstract

The invention discloses an axle tube structure of a vehicle axle, which comprises a shaft tube body, a shaft sleeve, a reinforcing rib, a limit ferrule, a sealing groove ring, a threaded groove and a threaded protrusion. The fixed base section has a reinforced raised section in the middle and a fixed support section at one end, which can effectively disperse the load of each part and reduce the risk of bending or even breaking the bushing; the bushing is equipped with a limit ferrule and connected by welding, which can The connection between the shaft sleeve and the limit ferrule is more firm, the shaft tube body is sleeved in the limit ferrule, and the limit ferrule can fix the shaft tube, which can prevent the shaft tube from moving in the shaft sleeve; the inner circumference of the shaft sleeve Both ends are equipped with sealing groove rings, which can prevent dust from entering the shaft sleeve and ensure the cleanliness of the shaft sleeve; there are reinforcing ribs on the outer surface of the shaft tube body, which can enhance the strength of the shaft tube , so that it will not break, the shaft tube body, shaft sleeve and limit ferrule are all cast from alloy steel as an integrated structure. The alloy steel has excellent anti-corrosion and wear resistance and high strength.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an axle tube structure of an axle. Background technique [0002] The automobile axle (also known as the axle) is connected to the frame (or load-bearing body) through the suspension, and the wheels are installed at both ends. The role of the axle is to bear the load of the car and maintain the normal driving of the car on the road. The design of the existing axle tube structure is unreasonable, the connection between the axle tube and the bushing is not firm enough, it is easy to loosen and affect the normal use of the connecting bush, and the strength of the axle tube and the bushing is not good, and it needs to carry a large load during transportation. Especially when the vehicle is running at high speed and the road is uneven, the axle tube and bushing of the bridge body will often bend or even break, posing potential safety hazards.
