Embodiment Construction
[0015] The structure of the present invention is described in detail below in conjunction with accompanying drawing:
[0016] see figure 1 , figure 2 , image 3 , which is a specific structure of the present invention, a magneto-rheological damper with a cracked piston double rod, which includes a piston rod 11, a piston rod 13, a piston 5, a working cylinder 2 and an external electromagnet 1; wherein: the piston 5 consists of a piston body 5, two sliding damping blocks 6, and a position adjuster for sliding damping blocks. The piston body 5 is in the shape of a cuboid, and the two short sides of the longitudinal section of the piston body 5 made of magnetically conductive materials are arc-shaped E. The two long sides of the longitudinal section of the piston body 5 have two symmetrical grooves 3 passing through the piston body 5 in the axial direction. The grooves 3 are isosceles trapezoidal in the axial direction of the piston body 5. There is an axial strip-shaped thro...

The invention discloses a gapped magneto-rheological damper with two piston rods out. The magneto-rheological damper comprises a piston, two piston rods, a working cylinder and an external electromagnet, the piston comprises a rectangular piston body, two slide damping blocks and a slide damping block position adjuster, two short sides of the vertical section of the piston body are arc-shaped, two long sides of the vertical section of the piston body are axially provided with two symmetrical grooves through the piston body, the two slide damping blocks are mounted in the two grooves respectively and are fixed on the slide damping block position adjuster, the slide damping block position adjuster is mounted in a strip through hole at the bottoms of the two grooves, the vertical section of an inner chamber of the working cylinder is identical with that of the piston in shape and is larger than that of the piston in area, the external electromagnet is fixed on a shell of the working cylinder, and the piston is mounted in the working cylinder filled with magneto-rheological fluid.
Description
technical field [0001] The invention belongs to a magneto-rheological damper, in particular to a magneto-rheological damper with cracked pistons and double-outlet rods. Background technique [0002] Magneto-rheological damper is an intelligent damping device. The structure of ordinary magnetorheological damper is to install a piston in the working cylinder, and fill the working cylinder with magnetorheological fluid, and adjust the pressure applied to the working cylinder by controlling the power supply. The electromagnetic field strength of the internal magnetorheological fluid changes the viscosity of the magnetorheological fluid in the working cylinder, so that when the magnetorheological fluid in the working cylinder is squeezed through the working gap between the outer peripheral wall of the piston and the inner peripheral wall of the working cylinder Different damping forces can be obtained. Because the working gap between the outer peripheral wall of the piston and th...
