Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
Embodiments of the present patent are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present patent and are not to be construed as limiting the present patent.
Referring to fig. 1, an air bag type buffer cavity structure of a shock absorber comprises a cylinder body 8 and an air cylinder 5, wherein an outer plug 7 is arranged at the bottom of the air cylinder 5, an upper seat 1 is arranged at the top of the cylinder body 8, and a tail cover 9 is arranged at the bottom of the cylinder body 8; the top of the cylinder 5 is communicated with the inside of the cylinder body 8 through the cylinder seat 3 and the connecting pipe 2 to form an oil duct; an adjusting valve 4 is arranged on the cylinder seat 3; the cylinder body 8 is internally provided with a piston 19, a valve plate 18, a cushion block 17 and a lock nut 16 which are matched to form a compression and rebound loop of the shock absorber; a piston rod 10 is arranged on one side of the piston 19 close to the tail cover 9, and a lower seat 11 is arranged on one end of the piston rod 10 far away from the piston 19; an air bag 6 is arranged in the air cylinder 5, and an air chamber is formed between the air bag 6 and the outer plug 7.
As a preferred embodiment of the present utility model, a plurality of through holes are formed around the piston 19.
As a preferred embodiment of the utility model, the side of the air bag 6 near the outer plug 7 is provided with a groove structure matched with the side surface of the outer plug 7.
Compared with the prior art, the inner side convex groove of the air bag 6 can be fixed on the outer plug to prevent falling off, and the small circular arc convex groove on the inner side and the outer side replaces the sealing ring 13 to form an effective sealing effect. Then the air bag 6 and the outer plug 5 are fixed together, and the air pressure is directly injected into the cylinder 5 from the lower end of the cylinder. The innovative structure of the present utility model eliminates the need to combine multiple parts such as the diaphragm 12, the seal ring 13, the wear ring 14, etc. to form the air chamber together with the outer plug 15 as in the prior art, and eliminates the need to fix the diaphragm 12 in a certain position and then inject hydraulic oil to prevent the air chamber from being too much or too little as in the prior art.
When the piston 19 slides upwards, most of hydraulic oil in the cylinder body 8 flows to the lower part of the piston 19 through the holes around the piston 19 to open the valve plate 18 below the piston 19, but the piston rod 10 also enters the cylinder body 8 to reduce the hydraulic oil storage space, and the hydraulic oil is extruded by the weak points of the upper seat 1, the connecting pipe 2, the cylinder seat 3 and the regulating valve 4 which can flow into the cylinder 5 to automatically find the air bag 6 to compress the air chamber to fill the reduced hydraulic oil storage space. When the piston 19 slides downwards, hydraulic oil flows to the upper part of the piston 19 through the valve plate 18 above the piston 19 at Kong Chongkai around the piston 19, but the piston rod 10 gradually withdraws from the inside of the cylinder body 8, so that the storage space of the hydraulic oil is increased relative to that obtained before, and the hydraulic oil stored in the cylinder 5 by pressing the air bag 6 has better places, so that the hydraulic oil slowly flows back to the inside of the cylinder body 8. Unlike the prior art, the diaphragm 12 can not rely on the sealing ring 13 and the wear-resistant ring 14 to move back and forth all the time in a certain direction, and the sealing ring 13 and the wear-resistant ring 14 are easy to break down after long time wear, and even the position of part of the interior of the cylinder 5 is smooth and quick. The novel structure of the utility model can effectively avoid the problems, and simultaneously improves the working linearity and the high-speed working efficiency of the shock absorber, so that the shock absorber can exert better performance.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
