Problems solved by technology

Designing the vehicle height control system separately will not only increase the complexity of the suspension system, bring inconvenience to the control and design, but also increase the system cost
The vehicle height control and passive vibration reduction are integrated. Since the stiffness of the elastic elements of the passive vibration reduction system and the damping coefficient of the damping elements are not adjustable, the vehicle can only guarantee the vibration reduction effect under the design conditions, and cannot real-time adjustments to the operating conditions and road conditions

Embodiment Construction

[0020] The structure of the present invention is specifically described below in conjunction with the accompanying drawings:

[0021] Refer to attached figure 1 , which shows the basic structure of a controllable automotive magnetorheological shock absorber with vehicle height adjustment. Among them, 1 is the system controller, 2 is the piston rod of the magneto-rheological hydraulic cylinder with damping characteristics, 3 is the magnetorheological fluid, 4 is the cylinder body of the magnetorheological hydraulic cylinder with damping characteristics, and 5 is the magneto-rheological hydraulic cylinder with damping characteristics. The piston head of the rheological hydraulic cylinder, 6 is the excitation coil on the piston head, 7-10 is the four-way magneto-rheological valve, 11 is the gear pump, 12 is the motor, 13 is the accumulator, and 15-16 is the two-way magneto-rheological valve. The rheological switching valve, 17, is an annular damping gap formed between the pisto...

Abstract

The present invention relates to a controllable car magnetorheological shock absorber with vehicle weight regulation function. It comprises direction control valve formed from four magnetorheological valves, two magnetorheological switching valves, magnetorheological hydraulic cylinder with damping characteristics, hydraulic pump, motor and control loop, etc. Said invention uses magnetorheological liquor as hydraulic medium for transferring energy, and uses the hydraulic pump as drive device. Besides, said invention also provides the working principle of said magnetorheological shock absorber, and said magnetorheological shock absorber not only can accurately control vehicle height, but also can produce controllable damping force.

Description

technical field [0001] The invention belongs to the technical field of automobile vibration reduction, and in particular relates to a controllable automobile magneto-rheological shock absorber with a vehicle height adjustment function. technical background [0002] Most of the traditional car suspension systems do not have the function of vehicle height adjustment. The car suspension system with car height adjustment function can automatically adjust the car body height, which has many advantages: maintaining a certain car body height can not only keep the car running stably, but also keep the direction of the car's headlight beam unchanged; when the car When driving at high speed, lowering the height of the vehicle body helps to reduce air resistance, which not only improves the power and economy of the vehicle, but also suppresses the gas lifting force that makes the vehicle body float, and increases the steering stability of the vehicle when driving in a straight line; W...
