Control arm assembly

Abstract

The invention relates to a control arm assembly which is applied to a vehicle independent suspension structure. The control arm assembly comprises two connecting arms and three spherical hinge structures, the two connecting arms form a V shape, and the three spherical hinge structures are arranged on the end portions of the two connecting arms respectively. One end portions of the two connecting arms are together connected to the first spherical hinge structure of the three spherical hinge structures, the other end portions of the two connecting arms are connected to the second spherical hinge structure and the third spherical hinge structure of the three spherical hinge structures respectively, the first spherical hinge structure is used for being connected with an axle wheel edge steering knuckle of a vehicle, and the second spherical hinge structure and the third spherical hinge structure are used for being connected with a vehicle frame of the vehicle. The control arm assembly can avoid movement interference between tires and a suspension and the vehicle frame in the vertical jumping process and the steering process of the tires as much as possible, a longer control arm structure also can be adopted to reduce the tilt angle of the control arm when the tires jump, the optimization difficulty of the control arm is reduced, and the stress condition of the control arm is improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a control arm assembly. Background technique [0002] In engineering vehicles, the suspension is to ensure that there is an elastic connection between the wheel or axle and the vehicle load-bearing system (frame or load-bearing body), and it can transmit loads, ease shocks, dampen vibrations, and adjust the body of the vehicle during driving. A general term for devices related to location, etc. Among the several types of suspension, the left and right wheels of the independent suspension do not directly affect each other, and the impact load received by the suspension and transmitted to the body is small, which is beneficial to improve the ride comfort of the vehicle and the grounding performance of the tires, and also Tilting and vibration of the vehicle body can be reduced. From the perspective of the structure of the independent suspension, it mainly includes a guiding m...

Problems solved by technology

However, due to the existence of the upper bushing, the length of the upper cross arm is shortened, and when the tire is beating the same stroke, the swing angle of the upper cross arm increases, which makes it more difficult to optimize the upper and lower cross arms; on the other hand, the upper cross arm The reduction in the length of the cross arm will also increase the force on the upper cross arm

In addition, the existing double wishbone independent suspension also has the problem of interference between the upper wishbone assembly and other components
