Lower plate of large shaft sleeve of lower suspension arm

Abstract

The present invention provides a lower plate of a large shaft sleeve of a lower suspension arm. The lower plate of the large shaft sleeve of the lower suspension arm is characterized by comprising a body, a trapezoidal surface and an arc-shaped surface. The trapezoidal surface and the arc-shaped surface form the body, the joint between the trapezoidal surface and the arc-shaped surface forms a groove, a fixing hole is formed in the trapezoidal surface, necks are formed in the both sides of the fixing hole, a plurality of mounting holes are formed in the arc-shaped surface, a protective layer wraps the body, and sealing rings are mounted on the fixing hole and the mounting holes. The lower plate of the large shaft sleeve of the lower suspension arm can be better connected with an upper plate of the large shaft sleeve of a front lower suspension arm and a stabilizer bar holder of the large shaft sleeve of the front lower suspension arm through welding, the performance of the upper plate assembly of the large shaft sleeve of the front lower suspension arm is improved, and the conditions of deformations caused by untight welding, cracks generated after use and the like are avoided. The protective layer is also arranged, the protective layer is a waterproof and high temperature-resistant protective layer, thus the lower plate of the large shaft sleeve of the lower suspension arm is protected, the lower plate of the large shaft sleeve of the lower suspension arm is prevented from being damaged by the outside moisture or heat, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a lower plate of a large shaft sleeve of a lower swing arm. Background technique [0002] The lower plate of the large shaft sleeve of the lower swing arm is a part of the lower swing arm assembly of the car. The lower swing arm assembly of the car is located between the car body and the steering wheel. The longitudinal force and lateral force during braking and turning are one of the main components that determine the performance of the vehicle. It buffers the impact force transmitted from the uneven road to the frame or body, and attenuates the vibration caused by it to ensure that the vehicle can run smoothly. Driving, on the other hand, vibration easily deforms the loosely welded part of the existing lower swing arm assembly. After a long time, cracks will appear in the lower swing arm, which will affect the normal running of the vehicle and reduce the safety of the vehicle. [000...

[0002] The lower plate of the large shaft sleeve of the lower swing arm is a part of the lower swing arm assembly of the car. The lower swing arm assembly of the car is located between the car body and the steering wheel. The longitudinal force and lateral force during braking and turning are one of the main components that determine the performance of the vehicle. It buffers the impact force transmitted from the uneven road to the frame or body, and attenuates the vibration caused by it to ensure that the vehicle can run smoothly. Driving, on the other hand, vibration easily deforms the loosely welded part of the existing lower swing arm assembly. After a long time, cracks will appear in the lower swing arm, which will affect the normal driving of the vehicle and reduce the safety of the vehicle.

[0003] The lower plate of the large shaft sleeve of the lower swing arm is an important part of the lower swing arm assembly of the car. It cannot be fixed loosely or broken during use, which will lead to a short life of the lower swing arm assembly of the car and needs to be replaced frequently, increasing the service life of the car. cost

Because the large shaft sleeve of the lower swing arm is located between the car body and the steering wheel when the car is running, the accumulated water on the road will splash on the lower plate of the large shaft sleeve of the lower swing arm, resulting in corrosion damage to the lower plate of the large shaft sleeve of the lower swing arm , resulting in a short service life

The lower swing arm assembly of the car is composed of multiple parts, which must be installed firmly during installation. If it is loose, it will easily cause the car to break down and bring danger to the driver.
