Problems solved by technology

This type of double-rod magneto-rheological damper has a simple structure, but when the displacement of the damper is constant, the length of the working space is relatively large because there are piston rods protruding from both ends of the working cylinder.

Embodiment Construction

[0011] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0012] see figure 1 , which is a specific structure of the present invention, one end of the built-in rod 13 made of non-magnetic metal material is fixed on the bottom of the working cylinder through threads, and the other end of the built-in rod 13 passes through the sealing ring at the center of the piston 12 and bearing 11 stretch in the center through hole 14 of piston, and the diameter of built-in rod 13 is slightly smaller than the inner diameter of center through hole 14 of piston 10, and built-in rod 13 can slide in center through hole 14. The other end of the piston 10 made of high magnetic permeability metal material is connected to the piston rod 15 through threads, and the piston rod 15 also has a central through hole 2 and communicates with the central through hole of the piston 10 . The middle part of the piston 10 is wound with an excitation co...

Abstract

The invention discloses a built-in bar-type magneto-rheological damper, which consists of a working cylinder, a piston of which the core is provided with small and big holes, a piston rod and a built-in bar, wherein a magneto-rheological liquid is filled in the working cylinder. When the piston rod pushes the piston to move in the working cylinder, the piston rod enters or retreats from the working cylinder, and the built-in bar also enters or retreats from a through hole at the other end of the piston. Because the external diameter of the piston rod is the same as that of the built-in bar, the volume of the working cylinder is not changed; therefore, the aim of reducing the length of the damper is fulfilled.

Description

technical field [0001] The invention belongs to a magnetorheological damper, in particular to a built-in rod magnetorheological damper. Background technique [0002] Ordinary double-rod magnetorheological damper, its internal structure is to install piston rods symmetrically at both ends of the piston. When the piston moves in the working cylinder, one piston rod enters the working cylinder while the other piston rod goes from Withdrawing from the working cylinder keeps the volume of the magnetorheological fluid in the working cylinder constant. Because the output damping force of the double-rod magnetorheological damper has good symmetry performance, it is suitable for vibration reduction of cable stays and other occasions. This type of double-rod magneto-rheological damper has a simple structure, but when the displacement of the damper is constant, the length of the working space is relatively large because there are piston rods protruding from both ends of the working cyl...
