Problems solved by technology

The mechanism design of the current cage type constant velocity universal joint is unreasonable
The unreasonable design of the ball cage type constant velocity universal joint for automobiles will also cause unreasonable stress on the universal joint, and the universal joint will appear cracks from the stress concentration point, and it will break after long-term movement
Moreover, the current car universal joints are easily damaged due to the large friction between the car universal joints and other parts of the car after being used for a period of time during use.

Embodiment Construction

[0008] Combine below figure 1 Specific description embodiment:

[0009] Such as figure 1 As shown, the ball cage type constant velocity universal joint, the ball cage type constant velocity universal joint includes a connecting shaft 1 and a housing 2, the connecting shaft 1 is a stepped structure; the housing 2 includes The upper casing 3 and the lower casing 4, the upper casing 3 is a hollow cylinder, the inner wall of the upper casing 3 is closely attached to the wear-resistant inner casing 5, and the inner wall of the wear-resistant inner casing 5 is evenly distributed There are several channels 6, and bosses 7 are arranged between adjacent channels 6. The ratio of the minimum wall thickness of the channel 6 to the wall thickness of the upper casing 3 is 1:2, and the wall thickness of the bosses 7 is the same as that of the upper shell 3. The ratio of the wall thickness of the housing 3 is 3:1; the lower housing 4 is a hollow truncated cone, and the inner bottom of the l...

Abstract

The invention belongs to the technical field of universal joint tools, in particular to a ball cage type equal speed universal joint. The invention discloses the ball cage type equal speed universal joint, the ball cage type equal speed universal joint comprises a connection shaft and a shell; the connection shaft is of a step structure; the shell comprises an upper shell and a lower shell; the ratio of the wall thickness of a boss to the wall thickness of the upper shell is 3:1, the lower shell is a hollow conical table body, and a slot is formed in the bottom inside the lower shell; a first reinforced annular body is arranged at the joint, connected with the connection shaft, of the outer wall of the lower shell; the outer wall of the lower shell is provided with a second reinforced annular body. The ratio of the diameter of the first annular reinforced annular body to the diameter of the second reinforced annular body is 1:1.5. The ball cage type equal speed universal joint has the beneficial effects of reasonable structure, firm connection and long use time.

Description

technical field [0001] The invention belongs to the technical field of universal joints, in particular to a ball cage type constant velocity universal joint. Background technique [0002] CV joints for automobiles are part of the auto parts, mainly used in the indispensable transmission parts in the speed control system of the car, and play an important role in the operation of the speed control system of the car. The mechanism design of the current cage type constant velocity universal joint is unreasonable. The unreasonable design of the constant velocity universal joint for automobiles will also cause unreasonable stress on the universal joint. Cracks will appear in the universal joint from the stress concentration point, and it will break after long-term movement. Moreover, the current universal joints for automobiles are easily damaged due to greater friction between the universal joints for automobiles and other parts of the automobile after being used for a period of...
