Description

Technical Field

[0001] The utility model relates to the technical field of automobile swing arms, in particular to an adjustable swing arm used for an automobile suspension system. Background Art

[0002] Arm triangle refers to the swing arm, which is used for balancing and supporting. When the car is driving on uneven roads, the tire will swing up and down, which is achieved by the swing of the triangle arm. The tire is installed on the axle head, and the axle head is connected to the triangle arm through the ball head. The specific role of the automobile swing arm is the guide and support of the suspension. Its deformation affects the wheel positioning and reduces driving stability. If there is a problem with the front swing arm, it will feel that the steering wheel will shake, and it is easy to deviate after the hand releases the steering wheel, and it is difficult to control the direction at high speed.

In the utility model, the wheelbase of the swing arm is adjusted by adjusting the ball pin mounting plate, so that the vehicle can continue to be used, reducing the replacement cost of the swing arm, and the use range of the swing arm is increased, and it can be used on various models of vehicles. There are reinforcing ribs at the edge of the swing arm body, which increase the strength of the swing arm, increase the impact resistance of the swing arm, and extend the use time of the swing arm. The three slide grooves can increase the adjustment range of the ball pin mounting plate, which can not only adjust the length, but also adjust the angle, so as to cope with different slight deformation states.

[0004] The existing adjustable swing arm for automobile suspension system is not easy to adjust the installation distance due to the poor adjustment effect, thus limiting the installation position. Utility Model Content
