Problems solved by technology

The electrorheological dampers of these three structures can improve the ride comfort and handling stability of the car by changing their own damping force according to different road conditions, but they cannot adjust the damping force well according to the suspension amplitude.
In practical engineering applications, when the electrorheological damper is working, it is only...

Embodiment Construction

[0042] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0043] Such as figure 1 and figure 2 As shown, the present invention provides an electrorheological damper, including a cylinder 1, a piston rod 2, a piston assembly 3 and a damping adjustment device. The cylinder 1 is a hollow cylindrical body, and the hollow part inside the cylinder 1 is a cylindrical inner cavity storing electrorheological fluid. The piston assembly 3 is arranged in the inner cavity of the cylinder 1, and the piston assembly 3 has a plurality of orifices 35 through which the electrorheological fluid passes. The piston rod 2 is set to pass through the cylinder barrel 1 and t...

Abstract

The invention discloses an electro-rheological damper. The electro-rheological damper comprises a cylinder barrel, a piston rod, a piston assembly and a damping adjusting device, wherein the piston assembly is arranged in an inner cavity of the cylinder barrel; the piston assembly has a plurality of throttle holes for allowing an electro-rheological fluid to pass through; the piston rod penetrates through the cylinder barrel and the piston assembly and is connected with the piston assembly; and the damping adjusting device comprises first damping pins and second damping pins which are rotatably arranged inside the piston assembly and are used for adjusting the numbers of the throttle holes in open or closed states, a frequency damping adjusting device connected with the first damping pins, and an amplitude damping adjusting device connected with the second damping pins. According to the electro-rheological damper, the first damping pins and the second damping pins are arranged inside the piston assembly, and the numbers of the throttle holes in open or closed states are adjusted through the first damping pins and the second damping pins, so that the damping force of the damper is changed, and the purpose of damping adjustment is achieved.

Description

technical field [0001] The invention belongs to the technical field of dampers, in particular, the invention relates to an electrorheological damper. Background technique [0002] At present, there are three main structures of electrorheological dampers used in suspension systems: single-rod single-cylinder structure, double-rod double-cylinder structure and rotary structure. The electrorheological dampers of these three structures can improve the ride comfort and handling stability of the car by changing their own damping force according to different road conditions, but none of them can adjust the damping force well according to the suspension amplitude. In practical engineering applications, when the electrorheological damper is working, it is only to quickly consume vibration energy, without considering the characteristics of the suspension amplitude (small amplitude frequency is fast, large amplitude frequency is slow), which will cause heat generation when the damper i...
