Automobile suspension swing arm device

Abstract

The invention discloses an automobile suspension swing arm device, which comprises a swing arm body, an auxiliary bushing component, a ball head pin component and a main bushing component; the swing arm body is made through solid forging, and a through hole is formed in the middle of the swing arm body; the ball head pin component comprises a welding plate, a ball head pin, a ball head pin boss, a dust cover, a ball head pin sleeve and a ball head pin base plate; one end of the welding plate is welded onto the outer wall of the ball head pin boss; the ball head pin component is welded onto the top end of the swing arm body through the other end of the welding plate; the main bushing component is connected to the right side of the bottom end of the swing arm body through a bolt; the main bushing component comprises an inner casing, a left rubber sleeve, an outer casing, a metal framework and a right rubber sleeve; the auxiliary bushing component is connected to the left side of the bottom end of the swing arm body through a bolt. The automobile suspension swing arm device is not only simple in structure, light in weight and high in strength, but also simple in installation and firm in connection. In addition, the automobile suspension swing arm device is good in damping effect, wear-resistant and long in service life, and the safety and stability of travelling are improved.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile suspension swing arm device. Background technique [0002] The main function of the automobile suspension system is to buffer and absorb the vibration from the wheels, and to transmit the driving force and braking force. The automobile suspension system includes many components, among which the automobile suspension swing arm device is its core component. On the one hand, the automobile suspension swing arm device is connected to the steering mechanism of the automobile through the ball pin, and on the other hand, it is connected to the chassis through the bushing. Under certain driving conditions, it is necessary to generate action force and reaction force to control the driving direction and ensure the smooth driving of the vehicle. Therefore, the structural rigidity, strength, processing accuracy, shock resistance and wear resistance of the automobile ...

AI Technical Summary

Problems solved by technology

[0003] At present, the shapes of automobile suspension swing arm devices are various. The shape of ordinary car swing arm devices is relatively simple, and the processing accuracy requirements are low. In order to meet the requirements of safety and reliability, they are all made relatively heavy; Complex, fine structure, light weight, but requires high machining accuracy, difficult to manufacture, and difficult to guarantee safety and reliability

In addition, the ball head of the existing ball stud is usually pressed into the installation hole of the car swing arm by extrusion force, which is difficult to install, and it is difficult to ensure the installation clearance, resulting in laborious steering, vibration and jamming.
