Example Embodiment

[0016] The technical solution of this patent will be described in further detail below in conjunction with specific embodiments.

[0017] See Figure 1-3 , An automobile front suspension lower swing arm assembly, comprising a lower swing arm upper body 1, a lower swing arm lower body 2, an upper bushing 3, a lower bushing 4 and a ball joint assembly 5. The lower swing arm lower body 2 has a U The U-shaped structure of the lower arm body 2 is easy to form. The U-shaped structure of the lower arm lower body 2 is provided with reinforcing ribs 6, and the two sides of the U-shaped opening of the lower arm lower body 2 are provided with flanges 7 respectively. The upper body 1 is a flat plate of equal thickness. The thickness of the upper body 1 of the lower swing arm is uniform everywhere, so that the force is balanced everywhere, which is convenient for stamping and forming. The upper body 1 of the lower swing arm and the lower body 2 of the lower body 2 are fixedly connected with t...

Abstract

The invention relates to an automobile front suspension lower swing arm assembly comprising a lower swing arm upper unit, a lower swing arm lower unit, an upper lining sleeve, a lower lining sleeve and a ball assembly. The section of the lower swing arm upper unit is in a U shape, a reinforcement rib is arranged in the U-shaped structure of the lower swing arm upper unit, and flanges are arranged on two sides of the U-shaped openings of the lower swing arm upper unit; the lower swing arm upper unit is a planar member with uniform thickness; the flanges of the lower swing arm upper unit and upper swing arm lower unit are fixedly connected. The U-shaped section is formed by welding the lower swing arm upper unit and the lower swing arm lower unit, the entire strength of the lower swing arm is increased effectively, assembling and fixing are facilitated, the housing of the ball assembly and the lower swing arm lower unit are in an integral structure, and the lower swing arm can be used safely after a ball pin is wore; the automobile front suspension lower swing arm assembly has the advantages of safety and reliability, high technology content and high operation stability and smoothness, vibration transmitted to an auxiliary frame by the lower swing arm during driving can be reduced, noise produced by the lower swing arm and the auxiliary frame during driving can be reduced, and the comfort of the entire automobile is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile front suspension lower swing arm assembly. Background technique [0002] The suspension of a car is an assembly that connects all transmission and connection devices between the car body and the wheels. Its main function is to transmit all forces and moments acting between the wheels and the body, and to slow down the vibration transmitted from the wheels to the body during driving. , to improve the stability and comfort of driving. The suspension includes front suspension and rear suspension. The longitudinal force and lateral force during braking and turning are one of the key components that determine the performance of the vehicle. [0003] The lower swing arm assembly of the front suspension is mainly connected with the front sub-frame assembly through the front bush and the rear bush, and connected with the steering knuckle and steering guide mechanism through the s...
