Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] see figure 1 As shown, a special-shaped symmetrical buffer with constant damping of the present invention includes a symmetrical working cylinder 11, a cylinder head A12 and a cylinder head B13 installed at both ends of the symmetrical working cylinder 11, and two groups of variable cross-sections with identical structures and symmetrical installations. The piston module, and the viscous fluid 4 filled inside the symmetrical working cylinder 11 .

[0013] see figure 1 As shown, the symmetrical working cylinder 1 is a cylindrical cylinder with a circular cross-section, the inner diameter of which is the smallest in the middle, the largest at both ends, and the rest changes according to the linear law; the variable-section piston module includes the variable-section piston 22 and the variable-section piston. The round rod 21 on...

Abstract

The invention discloses a constant-damping special-shaped symmetrical buffer, and belongs to the field of damping buffer vibration reducing instruments. The constant-damping special-shaped symmetricalbuffer comprises a symmetrical working cylinder, a cylinder cover A and a cylinder cover B mounted at the two ends of the symmetrical working cylinder, two variable section piston modules of the completely same structures and symmetrically mounted, and a viscous fluid 4 fully filled in the symmetrical working cylinder; round rods in the two sets of variable section piston modules penetrate through the cylinder cover A and the cylinder cover B, and can freely move; the outer walls of the variable section pistons and the inner walls of the symmetrical working cylinder form an inclined gap for enabling the viscous fluid to freely flow; the cross section of the inclined gap is the same in each place; the flowing direction of the inclined gap in the viscous fluid is aslant intersected with themoving directions of the variable section pistons; and the inclined intersecting angle is 30-45 degrees. The buffer has the advantages of symmetrical damping force and relatively constant damping force.

Description

technical field [0001] The invention relates to the field of damping, buffering and vibration-reducing instruments, in particular to a special-shaped symmetrical buffer with constant damping. Background technique [0002] The viscous damper is an intelligent vibration reduction instrument. The existing viscous damper is to install a piston in the working cylinder and fill the cylinder with viscous fluid. There is no need for an external power source to adjust the damping coefficient of the viscous fluid to achieve damping. Change, the gap between the outer wall of the piston and the inner wall of the working cylinder in this type of viscous damper is constant or variable. Existing viscous dampers result in significant changes in damping regardless of changes in operating clearance. Therefore, it is of great significance to design a liquid shock absorber with fairly constant damping force. Contents of the invention [0003] The technical problem to be solved by the presen...
