A control arm assembly

Abstract

The invention relates to a control arm assembly, which is applied to an independent suspension structure of a vehicle, which includes two V-shaped connecting arms and three ball joint structures respectively arranged at the ends of the two connecting arms , each of the two connecting arms has one end connected to the first spherical joint structure among the three spherical joint structures, and the other ends of the two connecting arms are respectively connected to the three spherical joint structures The second spherical joint structure and the third spherical joint structure in the structure, the first spherical joint structure is used to connect the axle wheel steering knuckle of the vehicle, and the second spherical joint structure and the third spherical joint structure are used for for connecting to the frame of the vehicle. The present invention can avoid as far as possible the movement interference between the tire jumping up and down and the tire steering process with the suspension and the frame, and can adopt a longer control arm structure to reduce the swing angle of the control arm when the tire jumps, and reduce the optimization difficulty and improve the force condition of the control arm.

Description

Technical field [0001] The invention relates to the field of engineering machinery, and in particular to a control arm assembly. Background technique [0002] In engineering vehicles, the suspension is to ensure that the wheels or axles have an elastic connection with the vehicle's load-bearing system (frame or load-bearing body), and can transmit load, alleviate impact, attenuate vibration, and adjust the body of the vehicle during driving The general term for related devices such as location. 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 conducive to improving the ride comfort of the vehicle and the grounding performance of the tires. Can reduce the tilt and vibration of the body. In terms of the structure of the independent suspension, it mainly includes a guiding mechanism, a damping element and an ...

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
