Abstract

The invention discloses a lower swinging arm of an automobile and relates to the field of automobile chassis suspension system. A lower swinging arm body takes a shape of four connecting arms which are mutually connected, namely a first connecting arm, a second connecting arm, a third connecting arm and a fourth connecting arm, in addition, the connecting arms meet a connection relationship; an included angle formed by the first connecting arm and the second connecting arm is an obtuse angle; an included angle formed by the second connecting arm and the third connecting arm is an acute angle;an included angle formed by the third connecting arm and the fourth connecting arm and an included angle formed by the fourth connecting arm and the first connecting arm are right angles or acute angles. A reinforcing arm is arranged between the first connecting arm and the fourth connecting arm, due to adoption of the intensified shape and structure, the strength of a swinging arm assembly is improved, and the problem of easy deformation is avoided; cross sections of the first connecting arm, the second connecting arm, the third connecting arm and the fourth connecting arm are I-shaped, so that the material of the connecting arms is saved, and meanwhile, the strength of the lower swinging arm body is further improved.

Description

technical field [0001] The invention relates to the field of automobile chassis suspension systems, in particular to an automobile lower swing arm. Background technique [0002] The lower swing arm assembly of auto parts is an important safety performance component in the automobile chassis system, including two left lower swing arm assemblies and right lower swing arm assemblies. The left and right swing arm assemblies are used in conjunction with each other and are symmetrical to each other in structure Its function is mainly to restrict the movement of the wheels relative to the body (or frame) according to a certain trajectory, support the body and be responsible for steering, and can buffer the vibration during driving. The car lower arm assembly is located between the car body and the steering wheel. It is the main guide rod of the suspension and can also function as a thrust rod. It bears the longitudinal and lateral forces when starting, braking and turning. One of ...
