Description

Technical Field

[0002] The straight arm of the car front suspension refers to a component in the suspension system of the car's front wheels, which is used to support and connect the wheels and the body so that the wheels can maintain stable movement on the road. The straight arm is usually a metal rod with one end connected to the wheel axle through a ball head and the other end connected to the body. The function of the straight arm is to support the weight of the wheel and absorb and reduce bumps and vibrations during driving through the springs and shock absorbers of the suspension system to provide driving comfort and road stability.

[0003] After searching, the specification of patent announcement number CN220281062U discloses a straight arm for automobile front suspension, wherein a ball head is fixedly provided at the upper end of the straight arm body, a first bushing is fixedly provided at the lower end of the straight arm body, and a second bushing is fixedly provided at the lower end of the straight arm body. Weight reducing grooves are provided on both sides of the straight arm body, a first reinforcing boss is fixedly provided at the middle of the two weight reducing grooves, and a second reinforcing boss is fixedly provided between the ball head and the first bushing. The straight arm is light in weight, has strong load-bearing performance, is not easily deformed when subjected to force, and has higher reliability.

[0004] However, due to the setting of the ball head and the bushing, the connection strength and the self-strength are improved by strengthening the boss. However, due to the small connection area of ​​the boss, the connection strength is low, and the ball head and the bushing are prone to deformation and fracture when subjected to other forces. At the same time, due to the setting of the strengthening boss and the reinforcement ring, it is inconvenient to install and disassemble the straight arm body and the ball head reinforced parts.

[0005] Therefore, we propose a straight arm for automobile front suspension. Utility Model Content
