Automotive suspension ball structure with high interference fit degree

Abstract

The invention discloses an automotive suspension ball structure with the high interference fit degree. The automotive suspension ball structure with the high interference fit degree comprises a ball cup and a connecting arm welded to one side of the ball cup. A ball groove is formed in the top of the ball cup, and a ball is movably mounted in the ball groove. A ball arm is welded to the top of the ball, and an abrasion-resistant plate which is located in the ball groove is arranged on the two sides and below the ball. The side, close to the ball, of the abrasion-resistant plate is slidably connected with the ball, one end of a connecting mechanism is welded to the side, away from the ball, of the abrasion-resistant plate, and the other end of the connecting mechanism is welded to the inner wall of the ball groove. The connecting mechanism comprises a base plate welded to the inner wall of the ball groove, and a fixed base is welded to the side, close to the ball, of the base plate. The automotive suspension ball structure with the high interference fit degree has the buffering capacity and can buffer vibrating force, the situation that the interference fit degree is changed under the influence of the vibrating force is avoided, and the transmission stability between a steering direction device and a steering wheel is prevented from being affected; and the interference fit degree can be increased, the structure is simple, and cost is low.

Description

technical field [0001] The invention relates to the technical field of suspension ball joints, in particular to an automobile suspension ball joint structure with high tightness. Background technique [0002] The suspension ball joint is used to connect the steering wheel and the universal wheel of the car. It is one of the key accessories of the car steering system. The quality and performance of the suspension ball joint directly affect the stability and safety of the car. The existing car suspension ball joints In the ball stud, the ball head of the ball stud pin is tightly fitted in the ball head seat. During use, there is often a problem of relative rotation between the ball head and the ball head seat due to insufficient tight fit, which affects the transmission between the steering steering gear and the steering wheel. stability. [0003] The patent document with the application number 201510360694.4 discloses an automobile suspension ball head structure with high ti...

AI Technical Summary

Problems solved by technology

[0004] Based on the technical problems existing in the background technology, the present invention proposes an automobile suspension ball head structure with a high degree of tightness, which is used to solve the problem that the tightness of the prior art does not meet the strict requirements, resulting in a limited range of use, and does not have Cushioning capacity, unable to slow down the impact of vibration force, it is easy to cause changes in the degree of tightness under the influence of vibration force, and affect the transmission stability between the steering steering gear and the steering wheel
