Front lower sway arm assembly

Abstract

The invention discloses a front lower sway arm assembly which comprises a lower sway arm body assembly (1). The lower sway arm body assembly (1) is provided with a ball head assembly (2), a front bushing (3) and a rear bushing (4), a sway arm (16) is arranged between the ball head assembly (2) and the front bushing (3), the rear bushing (4) is internally provided with an outer sleeve (14) and an inner sleeve (15) arranged in the outer sleeve (14), an annular rubber body (17) is arranged between the outer sleeve (14) and the inner sleeve (15), and the annular rubber body (17) is provided with a pair of limiting holes (18) which are symmetrical about the center of the inner sleeve (15). According to the front lower sway arm assembly, the requirement on the bearing capacity after the material is changed can be met, transmission mechanisms of a transmission shaft and the like can be avoided, the weight is the lightest, the cost is low, the universality is good, noise cannot be generated by friction between the rear bushing and a frame, and the service life of the rear bushing is long.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a front 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. The lower arm assembly of the front suspension is mainly connected with the front sub-frame assembly through the front bush and the rear bush The ball joint of the swing arm is connected with the steering knuckle and the steering guide mechanism. According to the...

[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. The lower arm assembly of the front suspension is mainly connected with the front sub-frame assembly through the front bush and the rear bush The ball joint of the swing arm is connected with the steering knuckle and the steering guide mechanism. According to the existing technology, the front lower swing arm assembly of the automobile is made of nodular cast iron, which is heavy, high in cost, and poor in versatility. At the same time, there is no avoidance structure, resulting in It cannot be used for other models, and cannot meet more than two models at the same time. The versatility is poor. If other materials are used to produce the front lower arm assembly of the automobile, according to the current structure, it cannot meet the load-carrying capacity requirements after the material is changed and cannot avoid transmission mechanisms such as drive shafts. , at the same time, the rear bush is connected with the frame, the friction between the rear bush and the frame will generate noise, the impact force on the rear bush is large, the rear bush is easily damaged, and the service life is short
