Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, the air spring shock absorber of the present invention comprises a first air spring 3 and a second air spring 13 with the same structure, wherein the top of the first air spring 3 and the top of the second air spring 13 are both fixedly connected with an upper connecting plate 1, and the bottom of the first air spring 3 and the bottom of the second air spring 13 are both fixedly connected with a lower connecting plate 2; the upper connecting plate 1 is a concave connecting plate, the lower connecting plate 2 is a convex connecting plate, and the first air spring 3 and the second air spring 13 are connected with the upper connecting plate 1 through the lower connecting plate 2 in a clamping manner; the above-described snap-fit connection is a common method in the prior art and will not be described in detail. The inner central parts of the first air spring 3 and the second air spring 13 are provided with buffer mechanisms; four air bags 4 surrounding the buffer mechanism are arranged in the first air spring 3 and the second air spring 13, the air bags 4 are uniformly distributed around the buffer mechanism, and the air bags are arranged at intervals of 90 degrees. Two connecting blocks 5 which are positioned at the upper side and the lower side are fixedly connected on the inner wall of the air bag 4, and a return spring 7 is arranged between the connecting blocks 5.
The buffer mechanism comprises two mounting plates 8 arranged at the tops and the bottoms of the first air spring 3 and the second air spring 13, and two buffer assemblies respectively and symmetrically arranged at the front side and the rear side of each mounting plate 8; the buffer assembly comprises two grooves 6 respectively arranged on one side, close to each other, of the two mounting plates 8, a moving rod 9 embedded in the grooves 6, two moving blocks 10 arranged on the moving rod 9 in a penetrating mode, and two support rods 11; the moving block 10 is connected with the moving rod 9 in a sliding manner; one end of the moving block 10 extends out of the groove 6, two ends of the supporting rods 11 are respectively hinged to the upper moving block 10 and the lower moving block 10 outside the groove 6, the two supporting rods 11 are in an X-shaped cross structure, and the two supporting rods 11 are hinged together through the cross point; buffer springs 12 are sleeved on the moving rod 9 between the groove 6 and the moving blocks 10 and between the two moving blocks 10.
