Method for connecting yoke and shaft

Abstract

The invention provides a method for connecting a yoke and a shaft. The yoke with a through type kidney-shaped inner hole and a transmission shaft with a transmission end manufactured to be a flat and square transmission end are provided; the flat and square transmission end of the transmission shaft, which is connected with the yoke, and the through type kidney-shaped inner hole of the yoke are assembled in mutual gap fit or interference fit so as to be integrally connected; and a fixed welding point or riveting point is arranged at the connection part of the transmission end and the kidney-shaped inner hole after the both are assembled. According to the method for connecting the yoke and the shaft, provided by the invention, the structure is simple; a more complex yoke machining process in the prior art is changed; compared with the former design, the method for connecting the yoke and the shaft, disclosed by the invention, has the advantages that the mechanical machining cost is reduced by 10-15%, the cost of a whole steering column is remarkably reduced, and the torque can be effectively transmitted, difficulty of sliding and a better transmission effect can be realized, the effect of safe transmission can be met, and the security of the whole vehicle is improved; and the method for connecting the yoke and the shaft, disclosed by the invention, is suitable for the field of steering columns of various automobiles.

Description

technical field [0001] The invention relates to a connection method of a device for changing the direction of a vehicle, that is, the field of a steering control device, in particular to a method for connecting a yoke and a shaft used in an automobile steering device. Background technique [0002] As we all know, the steering column, one of the key parts of the car, is related to the running performance of the whole vehicle. The quality of the steering column directly affects whether the overall steering of the car is stable or not, and even affects security. [0003] The yoke assembly in the steering column device is one of the core components of the steering transmission system of the automobile. The yoke assembly is a key part that directly affects the normal driving of the vehicle and whether the steering is safe. Therefore, the design and manufacture of the yoke assembly have very high requirements, such as figure 1 with figure 2 As shown, the yoke assembly under th...

Problems solved by technology

[0005] 2. According to the statistical data of follow-up maintenance, after a long period of steering operation of the automobile steering system, the thread of the drive end of the transmission shaft and the spline of the inner hole of the yoke are closely matched by the impact of the load, resulting in greater wear and tear. Timely maintenance will lead to the inability to fully transmit the steering power, or cause the steering system of the car to slip suddenly and fail, and in serious cases, an accident will occur.

[0012] To sum up, there is a need for a new type of yoke assembly, which can not only solve the problem of complex manufacturing and high cost of the lower yoke and drive shaft in the prior art, but also ensure safety while reducing costs
