A car front lower swing arm assembly

Abstract

The invention discloses an automobile front lower swing arm assembly which comprises a lower swing arm body assembly (1), wherein a ball head assembly (2) and a front bushing (3) are arranged on the lower swing arm body assembly (1); a swing arm (16) is arranged between the ball head assembly (2) and the front bushing (3); a front bushing connecting rod (4) is arranged inside the front bushing (3). The automobile front lower swing arm assembly is characterized in that the lower swing arm body assembly (1) is made of aluminum alloy; projection of the inner side surface of the swing arm (16) on the horizontal plane comprises a first straight line (5) parallel to the horizontal plane and an arc line (6) connected with the first straight line (5). According to the provided automobile front lower swing arm assembly, the bearing capability requirements after the material is changed can be met, and transmission mechanisms such as a transmission shaft can be avoided, so that the weight is lightest, the cost is low, the universality is good, the mounting is convenient, the reliability is good, and the rigidity adjustability of the front bushing is good.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile 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.

[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 front bushing is easy to be installed incorrectly during installation, the installation is troublesome, the reliability is poor, and the rigidity of the front bushing is poorly adjustable
