Problems solved by technology

However, when driving on a potholed road, the relative movement of the left and right wheels will also twist the stabilizer bar, which will have a rolling moment on the body, causing the body to shake and affecting ride comfort.
The smaller the stiffness of the stabilizer bar, the better the comfort and the poorer the stability
Therefore, the traditional passive stabilizer bar is difficult to balance the handling stability and comfort of the vehicle.

Abstract

The invention discloses an active transversal stabilization rod for an automobile. The active transversal stabilization rod for the automobile comprises a stabilization rod body of a door-shaped structure and a controlling device which is used for controlling the transverse rod stiffness of the stabilization rod body; the controlling device comprises a base which is fixed on a automobile frame, two supporting assemblies which are in single-freedom-degree sliding fit with the base and a driving device which is used for changing the distance between two supporting assemblies by driving the two supporting assemblies, the two supporting assemblies are arranged on transverse rods of the stabilization rod correspondingly in sliding and sleeving modes; according to the power of a line motor, the distance changes between two supporting bases can be realized through the power of a linear motor, thus the stiffness of the stabilization rod is changed while suspension rolling of the automobile occurs and active control over suspension rolling prevention of the automobile is realized; the transverse stabilization rod which can rapidly change suspension rolling stiffness of the automobile in real time is applicable for heavy commercial vehicles, and operation stability and comfort of the automobile are guaranteed.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an active lateral stabilizer bar for vehicles. Background technique [0002] The stabilizer bar is an important component in the automobile suspension system. The left and right wheels are flexibly connected through the stabilizer bar to increase the anti-roll performance of the vehicle. When a roll occurs, the left and right wheels move in opposite directions relative to the vehicle body, so the two ends of the stabilizer bar connected to the axle also move in opposite directions. At this time, the stabilizer bar is twisted; The body is connected at two points to generate two opposite forces, and these two forces form a moment on the body to restrain the roll of the body and improve the handling stability of the vehicle. However, when driving on a potholed road, the relative movement of the left and right wheels will also cause the anti-roll bar to twist, causing a rolling moment to ...
