Automobile suspension damping system

Abstract

The invention provides an automobile suspension damping system. The automobile suspension damping system comprises a signal receiving and transmitting module, the signal receiving and transmitting module is used for collecting driver operation information and information sensed by a sensor for sensing automobile body posture signals and transmitting the collected information to a control module, and the control module controls four control assemblies of an automobile body according to the received information. the damping system further comprises four damping modules, each damping module comprises wheels and a connecting rod, and the connecting rods are connected with a frame through friction dampers; the friction damper comprises a shell, a friction rod fixedly connected with the frame isarranged in the shell in a penetrating mode, oil hydraulic cylinders are arranged at the left end and the right end of the shell correspondingly, and each oil hydraulic cylinder comprises a telescopic block used for clamping the friction rod; and the four control assemblies control the working states of the oil hydraulic cylinders in the friction dampers of the four damping modules correspondingly, and then the clamping force of the telescopic blocks on the friction rods is adjusted. The automobile suspension damping system is simple in structural design, the suspension can rapidly obtain different damping forces needed by damping, the damping effect is good, and response is rapid.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment, and in particular relates to an automobile suspension vibration damping system. Background technique [0002] The safety and handling stability of the car are the most important performance requirements, and they are all directly related to the car suspension system. The basic function of the suspension system is to carry the body, maintain the posture of the body, and at the same time absorb and isolate the vibration from the road surface. Commonly used suspension structures include passive suspension, semi-active suspension and active suspension. [0003] The damping parameters of the shock absorber in the passive suspension cannot be actively adjusted, and cannot well meet the needs of different driving conditions; the damping of the shock absorber in the semi-active and active suspension systems can be actively adjusted through the controller, so that the car can be adjusted on d...

Problems solved by technology

[0003] The damping parameters of the shock absorber in the passive suspension cannot be actively adjusted, and cannot well meet the needs of different driving conditions; the damping of the shock absorber in the semi-active and active suspension systems can be actively adjusted through the controller, so that the car can be adjusted on different road surfaces. Good performance can be obtained under the same conditions and operating conditions, but its structure is complicated, and the cost and energy consumption are high.
