Air suspension arc-shaped guide arm

Abstract

The invention relates to the technical field of automobile parts and particularly relates to an air suspension arc-shaped guide arm. The guide arm comprises a lining, a guide arm body, a heat dissipation structure, a connecting structure, a limiting structure, a positioning structure and a driving structure, wherein the guide arm body of the arc-shaped structure is changed into an original Z-shaped structure and is in an arc shape, so that deformation and residual stress are smaller and the service life is longer when the guide arm body is machined, meanwhile, the arc-shaped structure of the guide arm body is matched with a circular-section axle for use, and due to the fact that the shape of the arc-shaped structure is closer to the circle, machining precision is improved; the axle and theguide arm can be mounted through smaller parts, meanwhile, the guide arm body and the axle are more convenient and faster to mount and dismount through mounting of the positioning structure, ventilation in the guide arm body is facilitated through the heat dissipation structure when the axle and the guide arm body shake, and the service life of the guide arm is prolonge; the guide arm body is rapidly cooled through air cooling, and therefore the situation that in the deformation process, the use performance is affected by the volume heat of the guide arm body is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an air suspension arc guide arm. Background technique [0002] Automobile is one of the most important means of transportation and plays an irreplaceable role in people's daily life; automobile suspension system is an important core component in the automobile, mainly used to transmit the force in all directions between the frame and the body and moment, relieve the impact load transmitted from the tire to the body due to uneven road surface and different load conditions, so as to ensure the stability of the car, the comfort of the driver and passengers, the stability of the cargo and prolong the service life of the related parts of the car. Some automobile suspension systems mainly solve the problem of automobile ride comfort by installing the air suspension airbag on the guide arm to form a stress buffer structure with the guide arm. [0003] However, since the guide arm is...

Problems solved by technology

[0003] However, since the guide arm is usually processed by one or two leaf springs, it may break in practical applications. The breakage of the guide arm will cause a great safety hazard to the vehicle, and the deformation and residual stress of the guide arm Larger, the guide arm takes up a lot of space, and most of the guide arm is bolted to the suspension, the installation and disassembly efficiency is low, and the lateral pressure of the bolt is large during use, which is easy to cause the bolt to break, and during the deformation process of the guide arm It is easy to generate heat, and it is easy to affect the performance of the guide arm when used for a long time
