Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, and more specifically to a connection structure between a half-axle sleeve and a bridge housing. Background Art

[0002] The axle housing is the base for installing the main reducer, differential, half-axle and wheel assembly. Its main function is to support and protect the main reducer, differential and half-axle, etc. The half-axle sleeve is an important part of the 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 together support the frame and the mass of each assembly on it. At the same time, it bears the road reaction force and torque transmitted from the wheels when the car is running, and transmits it to the frame through the suspension.

[0003] After searching, the existing patent number CN214647365U is a reinforced drive axle housing, including a bridge housing body, half-axle sleeves extending symmetrically on both sides of the bridge housing body, and both sides of the half-axle sleeves transition to the bridge housing body through oblique reinforcement surfaces, and a reinforcement component is arranged between the bridge housing body and the half-axle sleeve, and the reinforcement component includes a positioning strip, an arc-shaped reinforcement strip and a first triangular positioning seat, and a plurality of arc-shaped reinforcement strips are distributed in parallel at the connection between the bridge housing body and the half-axle sleeve. Through the oblique reinforcement surface, the bridge housing body and the half-axle sleeve are gradually transitioned in an arc shape, which avoids the occurrence of stress concentration, improves the strength and rigidity of the drive axle housing, and prolongs its service life. Moreover, welding a plurality of arc-shaped reinforcement strips between the bridge housing body and the half-axle sleeve can further improve the structural strength and prolong its service life.

[0004] The connection between the half-axle sleeve and the bridge housing is exposed under the vehicle body. During the driving process of the vehicle, it is easily disturbed by different roads, such as roads with accumulated water and residual gravel. The splashing water and gravel hit the connection between the half-axle sleeve and the bridge housing, causing corrosion or even deformation of the connection, resulting in poor use effect. Therefore, we propose a connection structure between the half-axle sleeve and the bridge housing to solve the above problems. Utility Model Content
