Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, the commonly used dampers include hydraulic dampers, air dampers and electromagnetic dampers. Although these dampers can adjust the damping, they cannot achieve the effect of simultaneously adjusting the stiffness and damping. Problem, a kind of magnetoelectric hybrid suspension type hydraulic damper proposed by the present invention

Abstract

The invention belongs to the field of hydraulic dampers, and particularly relates to a magneto-electric hybrid suspension type hydraulic damper. The hydraulic damper comprises a piston rod, an inner cylinder, an outer cylinder and a damping control valve. The inner cylinder is sleeved with the outer cylinder, and the outer cylinder and the inner cylinder are fixedly connected through a cylinder cover. A piston head is slidably connected with the interior of the inner cylinder, and the piston rod is arranged at one end of the piston head. Hydraulic oil is injected into the inner cylinder and the outer cylinder, the bottom of the inner cylinder communicates with the outer cylinder through a flow limiting hole and the damping control valve, and the damping control valve is controlled by a controller. After the displacement is detected by a displacement sensor, an adjusting valve element of the damping control valve is controlled through the controller, so that the speed for the hydraulicoil in the damper to repeatedly flow in the inner cylinder and in the outer cylinder is controlled, and the damping adjusting effect can be achieved. The rigidity and damping of the hydraulic damper can be adjusted in real time within one millisecond, so that the effect of fast damping is achieved.

Description

technical field [0001] The invention belongs to the field of hydraulic dampers, in particular to a magnetic-electric hybrid suspension hydraulic damper. Background technique [0002] As a device to provide motion damping and consume motion energy, the damper is widely used in automobiles, aerospace and other fields. Commonly used dampers include hydraulic dampers, air dampers, and electromagnetic dampers. Although these dampers can adjust the damping effect, they cannot achieve the effect of simultaneously adjusting stiffness and damping, so the application range has certain limitations. . [0003] A magnetic-electric hybrid suspension hydraulic damper is based on the electromagnetic principle, and a magnetic-electric hybrid suspension structure is added to the hydraulic damper for the first time. After the electromagnet is connected to the current, changing the direction and magnitude of the current can change the magnetic pole and magnetic strength of the electromagnet, ...
