Lever-mechanism-based air spring shock absorber assembly providing lateral force

Abstract

The invention discloses a lever-mechanism-based air spring shock absorber assembly providing lateral force. The lever-mechanism-based air spring shock absorber assembly comprises a shock absorber body. A shock absorber rod is arranged in the shock absorber body. The two ends of the shock absorber body are connected with a lateral force bushing and a shock absorber barrel correspondingly. The lever-mechanism-based air spring shock absorber assembly further comprises a fulcrum bushing fixed to the middle position of the shock absorber rod as the fulcrum. The lateral force bushing and the shock absorber barrel are matched with the fulcrum bushing. Acting force in the opposite directions is applied from the two ends of the shock absorber rod corresponding to form a lever mechanism providing the lateral force. According to the lever-mechanism-based air spring shock absorber assembly providing the lateral force, the lever mechanism is established by making full use of the internal space of the air spring shock absorber. On the premise of space limitation, the requirement for providing the lateral force for the air spring shock absorber is met, and damage to the shock absorber is reduced.Moreover, the change scope is small. Meanwhile, through the structure design, the air spring shock absorber is convenient to maintain.

Description

Technical field [0001] The invention belongs to the field of shock absorbers, and particularly relates to an air spring shock absorber assembly based on a lever mechanism to provide lateral force. Background technique [0002] The prior art air spring shock absorber assembly must be able to provide sufficient lateral force to support the vehicle body and protect the oil seal of the shock absorber from excessive lateral force. If it cannot provide sufficient lateral force, it will cause roll when turning. Large angle and fast roll angle speed affect driving comfort and safety. At the same time, the shock absorber is subjected to excessive lateral force, which causes premature damage to the oil seal of the shock absorber, which in turn causes oil leakage of the shock absorber. Failure and damage of the shock absorber. However, the air spring cannot provide sufficient force characteristics in the lateral direction like the traditional steel spring, and it needs to be able to provid...

Problems solved by technology

[0007] There is also a design to provide lateral force through the eccentric upper cover, but this structure also needs to occupy a large upper cover space, and the fixed position of the lower piston of the air spring and the air bag of the upper cover is eccentric. If the eccentricity is too large, the space is insufficient, and the air bag When there is no air, it may cause the fixed position of the upper cover airbag of the air spring to collide with the lower piston airbag and cause damage to the airbag. Therefore, this structure must have enough space in the vertical direction
