Abstract

The invention discloses an automobile guide arm connecting structure and aims to overcome the defects that an automobile suspension device is large in weight and poor in vibration reduction effect. The automobile guide arm connecting structure comprises a front bracket, an air bag spring and a guide arm made of a composite material, a shaft sleeve for assembling a wheel rotating shaft is mounted on the guide arm; the front bracket is connected to the front end of the guide arm, the air bag spring is mounted at the rear end of the guide arm, the front bracket and the upper end of the air bag spring are connected with an automobile frame, a sunken connecting portion is arranged at the rear end of the guide arm, the air bag spring is mounted at the connecting portion, a mounting hole is formed in the guide arm, the protective sleeve is mounted in the mounting hole, and the shaft sleeve and the protective sleeve are fittingly mounted. The automobile guide arm connecting structure is lightin weight and good in damping effect.

Description

technical field [0001] The invention relates to the field of automobiles, and more specifically, it relates to a connection structure of an automobile guide arm. Background technique [0002] Existing automobiles are equipped with suspension devices. Suspension devices are the general name of the force-transmitting connection devices between the vehicle frame and the vehicle axle. The impact load and vibration transmitted to the vehicle body from the road ensure the comfort of the passengers, reduce the dynamic load of the cargo and the vehicle itself, and improve the stability of the vehicle body. At present, most of the suspension devices use leaf springs. The leaf springs combine several pieces of alloy springs of equal width but unequal length to form an elastic beam, and then fix the elastic beam to the guide arm, so as to achieve the stability of the vehicle frame. and axle damping. However, due to the use of leaf springs, the self-weight of the suspension device i...
