Abstract

The invention discloses an air suspension guide arm with a lateral bend and a connecting structure of the air suspension guide arm and an axle, belongs to the technical field of special vehicles, and designs an arc-shaped guide arm to effectively overcome the technical defects of a Z-shaped guide arm. The anti-rolling sections are arranged on the two sides of the arc shape, the axle bearing bush is designed to be matched with the anti-rolling sections of the guide arm, relative rotation of the arc-shaped guide arm and the axle pipe can be completely eradicated, the strength of the arc-shaped guide arm is improved, and the service life of the arc-shaped guide arm is prolonged. Small double-row positioning key grooves are formed in the arc-shaped bottom and are used for precise positioning adaptation, so that the guide arm and the axle bearing bush are precisely centered, and stress is more uniform; a smooth transition part is designed at the arc-shaped rear part, so that the suitability is improved; lateral bending structures are designed at the tail ends of the arc-shaped guide arms and can be well matched with the gravity center of the airbag, the airbag is prevented from being damaged, the service life of the airbag is effectively prolonged, and the vehicle body weight is reduced. Compared with an arc-shaped guide arm in the prior art, the service life of the guide arm is prolonged by at least 50%, and major hidden dangers such as safety accidents caused by low strength of the guide arm are solved.

Description

technical field [0001] The invention belongs to the technical field of special vehicles, and particularly relates to an air suspension arc guide arm with a side-bend at the rear, a connection structure and a connection method with a vehicle axle. Background technique [0002] In modern production and life, automobiles have become the main means of transportation, and people have higher and higher requirements for the safety, comfort, life, and carrying performance of automobiles. [0003] Among them, the air suspension guide arm is an important core structure in the car. The air suspension guide arm is a suspension component connecting the axle and the frame, which is used to transmit the forces and moments between the axle and the body to constrain the axle relative to the vehicle. The movement track of the frame can relieve the impact load transmitted by the tire to the body under different loads such as turning, braking and bumping, ensure the smoothness of the car, drive...
