The invention discloses a vehicle suspension system, a vehicle provided with the vehicle suspension system, and a control method. The suspension system comprises a damper, a spring assembly, a lockingdevice, a ball screw and a driving motor, wherein the spring assembly comprises an upper tray, a lower tray and a damping spring; the locking device comprises an unlocking motor, a self-locking sleeve, a self-locking element and a support element, the unlocking motor is positioned at one side of a damper cylinder, the self-locking sleeve is provided with at least one sliding chute, the self-locking element is provided with bolts extending into the sliding chute, the inner circumferential wall of each sliding chute is provided with first self-locking teeth extending in a vertical direction, and each bolt is provided with second self-locking teeth meshed with the first self-locking teeth; the ball screw comprises a screw and a nut, and the nut cooperates with the lower tray to drive the lower tray to move vertically; and the driving motor is arranged on the damper cylinder and cooperates with the ball screw through a transmission mechanism to drive the nut to move relative to the screw.The suspension system disclosed by the invention is convenient to maintain, and accessories do not need to be replaced regularly, so that the use cost is reduced.
Description
technical field [0001] The invention relates to the field of vehicles, in particular to an automobile suspension system, an automobile with the same, and a control method. Background technique [0002] People pay more and more attention to the handling and comfort of automobiles, and the vehicle suspension system plays a vital role in the handling and comfort of automobiles. Suspension is the general term for all force transmission connection devices between the body and the wheels. It is mainly composed of springs (such as leaf springs, coil springs, torsion bar springs, etc.), shock absorbers and guiding mechanisms. When the car is running on different roads, since the suspension system realizes the elastic support between the body and the wheels, the vibration of the body and the wheels is effectively reduced to ensure the normal driving of the car. At the same time, it also causes phenomena such as pitching, nodding and rolling of the car body when the car starts, brak...
