Embodiment Construction

[0019] Such as Figure 1-4 As shown, in the present invention, the input shaft 1 is covered with an input shaft sleeve 3 and then inserted into the universal joint 2; the universal joint 2 is provided with a bolt hole 4, so that the input shaft sleeve 3 is used to reduce the distance between the input shaft 1 and the universal joint 2. After the bolts in the bolt holes 4 are tightened, the universal joint 2 is deformed so that the input shaft 1 is tightened.

[0020] There is a clearance fit between the input shaft 1 and the universal joint 2. After the input shaft 1 is inserted into the universal joint 2, bolts are used to fix the bolt holes 4 on the universal joint 2, and the universal joint is made 2 is deformed, and the input shaft 1 is clamped.

[0021] The shape of the input shaft sleeve 3 is exactly the same as the end of the input shaft 1, and the size is slightly smaller than the end of the input shaft 1. Because the input shaft sleeve 3 is made of rubber material, ...

Abstract

The invention discloses a connection structure of an automobile steering system, which is characterized in that an input shaft is sleeved in an input shaft sleeve and then inserted into a universal joint, a bolt hole is arranged on the universal joint, and a bolt is adopted for fixing at the position of the bolt hole. By means of the structure, the connection structure has the advantages of utilizing the shaft sleeve made of rubber materials and arranged at the input end to compensate gap error between the universal joint and the input shaft of a steering wheel in the processing process, greatly improving friction between the universal joint and the input shaft and removing metal friction noise.

Description

technical field [0001] The invention relates to an automobile steering system, in particular to a connection structure of an automobile steering system. Background technique [0002] The steering system of a car is a series of devices used to change or maintain the direction of driving or reversing the car. The function of the car steering system is to control the driving direction of the car according to the driver's wishes. The car steering system is very important to the driving safety of the car, so the parts of the car steering system are called security parts. After the steering system has been used for a period of time, problems such as idle steering, abnormal steering noise and steering wheel vibration will usually appear. After research, the cause of the above problem is the problem caused by the slippage at the connection between the input shaft of the steering wheel and the steering knuckle. [0003] At present, there is a certain gap between the input shaft of...
