Embodiment Construction

[0038] In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to th...

Abstract

The invention discloses a piston assembly which comprises a core body, a magnetic conductive ring, a magnetic resistance ring and an outer cover. The core body is installed on the piston rod and provided with a coil groove, a coil is arranged in the coil groove, and a wire of the coil penetrates through the piston rod to be connected with a power source. The two sets of magnetic conducting rings are installed in the coil groove and are sequentially arranged in the axial direction of the piston rod. The magnetic resistance rings are installed in the coil grooves, the two sets of magnetic conduction rings are spaced through the magnetic resistance rings, the wall thickness of the magnetic conduction rings is gradually reduced in the direction close to the magnetic resistance rings, and the outer cover is arranged outside the core body in a sleeving mode. The invention further discloses a full-channel effective magnetorheological damper which comprises a cylinder barrel, a floating piston, the piston assembly and a piston rod. According to the full-channel effective magneto-rheological shock absorber and the piston assembly thereof, the problem that engineering application is difficult due to the fact that the magnetic conduction ring is prone to magnetic saturation can be effectively solved, the advantages of the full-channel effective magneto-rheological shock absorber are more obvious especially for a small-size magneto-rheological shock absorber, and full-damping channel effectiveness can be basically achieved.

Description

technical field [0001] The invention relates to the technical field of magnetorheological damping, in particular to a full-channel effective magnetorheological damper and a piston assembly thereof. Background technique [0002] Magnetorheological damper has the characteristics of controllable damping, fast response, wide adjustable range, etc. It is one of the research hotspots of vibration suppression technology in recent years. The strength of the magnetic field can change the shear yield strength of the magnetorheological fluid, and finally achieve the purpose of changing the output damping force of the shock absorber. [0003] However, the effective working length of the damping channel of the common magnetorheological shock absorber is short, especially for the small size magnetorheological shock absorber, the output damping force is often very small and the adjustable range is not large. The full-channel effective magnetorheological shock absorber with magnetic conduc...
