Vehicle independent suspension combination lower swing arm structure

Abstract

The invention relates to a vehicle independent suspension combination lower swing arm structure. The structure comprises a ball pin, a cross connection rod, a spiral spring bracket, a pushing rod, a bush and a position adjuster; one end of the pushing rod is fixedly connected with the middle of the cross connection rod; the ball pin is arranged at the outer end of the cross connection rod, and thebush is arranged at the other end of the cross connection rod; the spiral spring bracket is connected with the cross connection rod through the position adjuster. According to the technical scheme, aforge part is adopted by key parts, and the bearing capacity of a suspension can be fully guaranteed; a swing body is divided into several small parts which are easily forged, cast and subjected to metal processing, in this way, the manufacturing technology gets even simpler, and the cost is also very low; if some part gets invalid or damaged, the part can be dismantled and replaced, the whole lower swing arm assembly does not need to be replaced, and the using cost is low; multiple functions of installing the bush, the ball pin, springs, a stable rod connection rod, a pushing rod connectionrod and the like are achieved; the functions of adjusting spiral springs and wheel centers are achieved, and wheel alignment is corrected.

Description

technical field [0001] The invention belongs to the technical field of independent suspensions, in particular to an automobile independent suspension combined lower swing arm structure. Background technique [0002] The car swing arm assembly is located between the car body and the wheels. It is the main guide rod of the suspension, which bears the longitudinal and lateral forces during starting, braking and turning, and can also act as a thrust rod, which determines the performance of the whole vehicle. one of the main components. Independent suspensions such as MacPherson independent suspension and double wishbone independent suspension have swing arms. [0003] The swing arm assembly of a general suspension is composed of a ball pin, a swing arm body and a bushing. In the swing arm assembly where the swing arm body is a forging or casting, the ball pin seat and the swing arm body are generally an integral structure, while in the swing arm assembly where the swing arm bo...
