Abstract

The invention discloses an automobile guide arm assembly structure and aims to overcome the defects that an automobile suspension device is large in weight and poor in vibration reduction effect. Theautomobile guide arm assembly structure comprises a front bracket, an airbag spring, a front guide arm, a rear guide arm, a shaft sleeve and two shaft clamps, the two shaft clamps are clamped on the outer wall of the shaft sleeve and are fastened and connected together; and the front guide arm and the rear guide arm are both made of composite materials. The rear end of the front guide arm is fastened and connected to the shaft clamp; the front end of the rear guide arm is fixedly connected to the other shaft clamp, the front bracket is connected to the front end of the front guide arm, the airbag spring is installed at the rear end of the rear guide arm, the front bracket and the upper end of the airbag spring are both connected with an automobile frame, the front guide arm is of an upwards-convex arc structure, and the rear guide arm is of a downwards-concave arc structure and is higher than the rear guide arm. The automobile guide arm assembly structure is light in weight and good invibration reduction effect.

Description

technical field [0001] The invention relates to the technical field of automobiles, more specifically, it relates to an automobile guide arm assembly structure. Background technique [0002] The main function of the automobile suspension device is to transmit the force and moment between the automobile frame and the axle, and to ease the impact load and vibration transmitted to the body from the uneven road surface, to ensure the comfort of the passengers, and to reduce the dynamic load of the cargo and the vehicle itself. Improve the stability of the car body. However, many automobile suspension devices currently used are heavy in weight, which increases the weight of the automobile, which is not conducive to the lightweight design of the automobile, and the vibration damping effect of the suspension device is not good, resulting in lower comfort of the automobile. Contents of the invention [0003] The invention overcomes the shortcomings of heavy weight and poor vi...
