Automobile suspension system capable of generating negative-value inclination angle

Abstract

The invention discloses an automobile suspension system capable of generating a negative-value inclination angle, which comprises a vibration damping device and a connecting rod device, wherein the vibration damping device is a triangular structure formed by interconnecting a main vibration damper, an auxiliary vibration damper and connecting rods, vibration damping springs are arranged on the main vibration damper and the auxiliary vibration damper, and a slide connection device which is connected with an automobile body in a slide way is arranged at the position of the joint the auxiliary vibration damper and the connecting rods; the connecting rod device is a trapeziform structure comprising a plurality of connecting rods, the upper end of the trapeziform structure is connected with thevibration damping device, the lower end of the trapeziform structure is rotatablely connected with the automobile body, the joint of the main vibration damper and the auxiliary vibration damper is connected with the joint of a wheel and an axle, and the joint of the main vibration damper and the connecting rods is connected with one corner of the upper end of the trapeziform structure. The invention is an automobile suspension system combining a double-spring structure and a hanging basket structure and can generate an inclination angle which is a negative value relative to an inclination direction when the automobile body turns, and the inclination angle is used for eliminating the feeling of being thrown outside of the automobile because of centrifugal force.

Description

technical field [0001] The invention relates to the technical field of automobile suspension systems, in particular to an automobile suspension system capable of generating negative roll angles. Background technique [0002] When the car turns, the centripetal force required by the human body to follow the turn is provided by the car, but the roll angle generated when the car turns makes the body roll in the opposite direction of the turn, while the supporting force supporting our human body produces a following. The required component of centripetal force is reversed, which directly reflects the feeling of being thrown out of the car in our human body, which has a huge impact on the ride comfort of passengers. How to suppress the roll angle of a car has always been a major problem that has plagued automotive engineers. From the stabilizer bar of the McPherson suspension system, to the double wishbone suspension system, and finally to the multi-link suspension system with t...

But this method also has its shortcomings: the first: large limitations, this method can only be used on expressways and overpasses, and it can't be done on urban highways with more complicated road conditions; second: the side of the road The inclination is fixed and cannot be adjusted to match the speed of the car and the required centripetal force
