Problems solved by technology

But there is still an obvious disadvantage, the structure is complicated, and because the working cylinder is cylindrical, the connecting rod piston can only perform one level of buffering when buffering the hydraulic pressure, so the buffering force is not enough, and it is easy to cause severe vibration of the vehicle body

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0012] Such as figure 1 As shown, a floating double buffer shock absorber includes a working cylinder and a liquid storage cylinder. A piston is movable in the working cylinder, and the piston is fixedly connected to the piston rod. A fixed ring is fixedly arranged in the middle of the working cylinder. Springs are fixedly arranged on the upper and lower surfaces of the piston. The working cylinder is composed of a first cylinder and a second cylinder with different diameters. A transition section is provided between the first cylinder and the second cylinder. The piston The surface of the tube body of the rod is provided with helically arranged oil grooves, and the head of the piston rod is provided with a buffer mechanism, and the buffer mechanism includes two sets of buffer pads and buffer blocks arranged in series. Wherein, a conn...

Abstract

The invention discloses a suspension double-buffering damper, which comprises a working cylinder and a liquid storage cylinder, wherein a piston is movably arranged in the working cylinder, and the piston is fixedly connected with a piston rod. The suspension double-buffering damper is characterized in that the middle of the working cylinder is fixedly provided with a fixing ring; the upper surface and the lower surface of the piston are fixedly provided with springs; the working cylinder consists of a first cylinder block and a second cylinder block, wherein the first cylinder block and the second cylinder block have different diameters; a transition section is arranged between the first cylinder block and the second cylinder block; the pipe body surface of the piston rod is provided with oil tanks which are arranged in a spiral line; the head part of the piston rod is provided with a buffer gear; the buffer gear comprises two sets of serial buffer cushions and buffer blocks. Compared with the prior art, the suspension double-buffering damper has the advantages of simple structure and easiness in production, the practical deformation amount of the piston can be effectively lowered, and the service life of the damper is prolonged.

Description

technical field [0001] The invention relates to a vehicle shock absorber which improves the stability of the vehicle during running, in particular to an air-suspended double-buffer shock absorber. Background technique [0002] The double-acting shock absorber is becoming more and more popular. The working principle of the double-acting shock absorber is that the impact and vibration from the road are transmitted through the cylinder to make the piston reciprocate in the working cylinder relative to the working cylinder. Valve and compensation valve to control the flow of damping oil in the working cylinder to achieve damping and shock absorption. When the external impact and vibration are very large, the shock absorber oil flow in the working cylinder is relatively large, the working load of the shock absorber is relatively large, and the shock absorber is easily damaged. I have previously applied for an invention patent called a two-way acting shock absorber. The technical...
