Carbon fiber composite material welding fork

Abstract

The invention discloses a carbon fiber composite material welding fork and belongs to the technical field of transmission part novel materials of transmission shafts of motor vehicles. A guide column with a thread hole is arranged at the upper end of a welding fork, a connecting bowl is arranged at the lower end of the guide column with the thread hole, two connecting shaft holes are arranged in the middle of the welding fork, the two connecting shaft holes are matched with connecting shafts, a connecting hole arranged under the welding fork is matched with a shaft head of a steering shaft, and the connecting positioning surface is matched with the positioning surface of the steering shaft, and the welding fork is formed by the carbon fiber composite material through one-time compression molding. The carbon fiber composite material welding fork has the advantages that the welding fork is formed by the carbon fiber composite material through one-time compression molding, the inner quality and external dimension accuracy can be guaranteed, the proportion of carbon fibers is small, the welding fork is light, the requirement of light weight of automobile parts is met, the carbon fiber material is applied to the automobile transmission parts, and thereby the pneumatic performance, the structural intensity and reliability of power transmission can be improved.

Description

technical field [0001] The invention relates to a carbon fiber composite material welding fork, which belongs to the technical field of new materials for transmission parts of automobile transmission shafts. Background technique [0002] At present, the conventional technology of connecting forks at both ends of the steering transmission shaft of an automobile has the problem of using castings, which have air holes and trachoma in the inner quality, and the operation is unreliable. Frequent inspection and replacement is required. In particular, heavy-duty vehicles are often found to be damaged in the connecting fork in an extremely harsh working environment, resulting in vicious accidents of car crashes and fatalities. What needs to be improved for this connection fork is to increase strength, reduce weight and improve reliability. The reliability of the connection fork is related to the structure and material selection of the connection fork. In view of this problem, rel...

AI Technical Summary

Problems solved by technology

[0002] At present, the problem with the common technology of connecting forks at both ends of the steering transmission shaft of automobiles is that castings are used, and there are pores and trachoma in the inner quality, which makes the operation unreliable.

Requires frequent inspection and replacement

Especially in the extremely harsh working environment of heavy-duty vehicles, it is often found that the connecting fork is damaged, resulting in vicious accidents of vehicle crashes and fatalities.
