Vehicle shock absorber, active suspension and vehicle

Abstract

The invention discloses a vehicle shock absorber, comprising a hydraulic shock absorber body (1), the hydraulic shock absorber body (1) including a shock absorber cylinder (15) and a (15) to form a shock absorber piston (14) in a closed space, the vehicle shock absorber also includes an oil pump (3), an oil storage container (4), a detection unit for collecting road condition information and The information controls the controller (5) to operate the oil pump (3), and the oil pump (3), the oil storage container (4) and the hydraulic shock absorber body (1) are connected to form a complete hydraulic circuit. In addition, the invention also discloses an active suspension including the vehicle shock absorbing device and a vehicle including the active suspension. The vehicle shock absorbing device of the present invention can actively adjust its own damping degree according to road condition information, thereby improving the driver's road feeling, vehicle operation stability and riding comfort.

Description

technical field [0001] The invention relates to the field of vehicle shock absorbing devices, in particular to a vehicle shock absorbing device. Furthermore, the invention also relates to an active suspension and a vehicle. Background technique [0002] With the rapid popularization of vehicles, people have higher and higher requirements for the ride comfort of the vehicle, and the shock absorber in the vehicle suspension structure directly affects the ride comfort of the vehicle. If the shock absorber is too soft, the body will jump up and down easily; if the shock absorber is too hard, small changes in the road surface will be directly transmitted to the body, which will lead to poor ride comfort of the vehicle. [0003] Existing suspension devices are mostly passive forms (such as figure 1 shown), usually includes a shock absorber 7, an upper swing arm 8, a stabilizer bar 9, a vehicle frame 10, a coil spring seat 11, a lower swing arm 12 and a front axle assembly 13.

AI Technical Summary

Problems solved by technology

When a vehicle using this type of suspension device is in motion, it passively bears the impact force of the ground, and relies on the shock absorber in the shock absorber of the suspension to passively weaken the impact force, and the impact force is transmitted to the occupant through the body, making the occupant feel uncomfortable. ; When the automobile is subject to lateral force and the vehicle body rolls, it is necessary to rely on the anti-roll bar 9 to counteract the roll. Comfortable, on the contrary, when the stabilizer bar 9 is hard, the driver’s road feeling is not good, the body is prone to more frequent and large lateral impacts, and the passengers will also feel uncomfortable
