Abstract

The invention discloses an intelligent self-energized absorber which comprises a piston, a piston rod, an outer cylinder and an inner cylinder. The piston rod is fixedly connected to the inner side of the outer cylinder, the piston is located inside the inner cylinder and is capable of moving up and down relative to the inner cylinder, a ball shaft sleeve is embedded on the inner wall of the outer cylinder, the outer wall of the inner cylinder is vertically sleeved with a plurality of piezoelectric rings, and the inner cylinder is then arranged in the ball shaft sleeve of the inner wall of the outer cylinder in a sleeved mode. Electrorheological elastic bodies are filled in the space, located above and below the piston, in the inner cylinder, and the electrorheological elastic bodies, the piezoelectric rings and an electronic control module are electrically connected. Energy generated by vibration of vehicles can be obtained, vehicle vibration information can be collected, the captured energy is used for supplying power for the electrorheological elastic bodies, the vibration information is used for self-adaptive control, different voltages are provided to control the damping of the electrorheological elastic bodies according to different road conditions, the absorber is made to meet the vibration reduction demands of the different road conditions, and therefore the riding comfortableness and the handling stability of vehicles can be improved.

Description

technical field [0001] The invention belongs to an automobile shock absorber, in particular to a self-powered intelligent shock absorber. Background technique [0002] At present, most automobiles still use passive suspension for vibration reduction. The damping coefficient of the shock absorber cannot be adjusted with the driving conditions. The design can only ensure good vibration reduction performance under a certain driving condition, and it is difficult to adapt to different conditions. road conditions, so the damping performance is limited. The active suspension can realize the optimal suspension performance under different driving conditions, and significantly improve the driving comfort and handling stability of the vehicle. However, since active suspension needs to consume a lot of energy to suppress the impact caused by uneven roads, although active suspension can significantly improve the overall performance of vehicles, high energy consumption has always been o...
