Detailed Description
In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
In the present embodiment, a center-mounted shock absorbing structure in the present invention will be described in detail by taking a two-wheeled vehicle as an example.
As shown in fig. 1 to 3, the middle damping structure in the present embodiment includes a frame 10, a rear wheel bottom fork 20, a hanger elbow 30, and a damping unit 40.
The body frame 10 is a main body frame of a two-wheeled vehicle and has a seat mount 11. A square frame 12 is connected below the seat mounting seat 11, and a connecting support rod 13 is connected to the square frame 12. A first hanging lug 14 is arranged on a beam of the square frame 12 close to the front wheel. The first lug 14 is directed towards the rear wheel.
The rear wheel flat fork 20 is connected to the rear wheel. The front end of the rear wheel bottom fork 20 is connected with the connecting support rod 13 through a bottom fork shaft 21. One end of the bottom fork shaft 21 passes through a through hole at the front end of the rear wheel bottom fork 20, the connecting support rod 13 and the other through hole at the front end of the rear wheel bottom fork 20 in sequence, and is fixed at the end by a bottom fork shaft damping nut 22 after passing through. The connected rear wheel bottom fork can rotate by taking the bottom fork shaft 21 as a rotating shaft.
Both ends of the hanger bend 30 are fixedly welded to the rear wheel bottom fork 20 in front of the rear wheel. The hanger bend 30 is angled toward the front end of the rear wheel fork 20 so that it is at an angle to the rear wheel fork 20. The joints of the two ends of the hanger bent pipe 30 and the rear wheel bottom fork 20 are provided with reinforcing pipes 31. The two ends of the reinforcing tube 31 are respectively connected with the ear hanging bent tube 30 and the rear wheel bottom fork 20. The reinforcement tube 31, the hanger bend 30 and the rear wheel bottom fork 20 form a triangular structure, so that the hanger bend 30 and the rear wheel bottom fork 20 are more firmly connected.
The top end of the ear tube 30 is provided with a second ear 32, the second ear 32 facing the front wheel.
The damping unit 40 includes a screw 41 and a damping spring 42 sleeved outside the screw 41. The front end of the screw 31 is connected with the first hanging lug 14 through a first damping screw 43 and a first damping hexagon nut 44, and the rear end is connected with the second hanging lug 32 through a second damping screw 45 and a second damping hexagon nut 46.
The installation process of the middle damping structure of the embodiment is as follows: firstly, the hanger bent pipe 30 is welded above the rear wheel bottom fork 20 in an inclined manner at a certain angle, and then the connection positions of the two ends of the hanger bent pipe 30 and the left side and the right side of the rear wheel bottom fork 20 are respectively connected by the reinforcing pipes 31, so that the reinforcing pipes 31, the hanger bent pipe 30 and the rear wheel bottom fork 20 form a triangular structure, the welding can be strengthened, and the stress can be reduced; then, a second hanging lug 32 is welded at the top end of the hanging lug bent pipe 30, and the first hanging lug 14 is welded on a cross beam close to a front wheel on the tetragonal body frame 12; then the front end of the rear wheel bottom fork 20 is connected with the connecting support rod 13 below the frame 10 through a bottom fork shaft 21 and a bottom fork shaft damping nut 24, so that the rear wheel bottom fork 20 is connected with the frame 10; finally, the front end of the damping unit 40 is connected with the first hanging lug 14 through a first damping screw 43, and the rear end of the damping unit 40 is connected with the second hanging lug 32 of 4 through a second damping screw 45. After the above connection, the shock absorbing unit after installation can be hidden in the internal space of the tetragonal body frame 12 below the seat mounting seat 11 on the vehicle body frame 10.
The damping principle of the middle damping structure of the embodiment is as follows: during the movement, the rear wheel bottom fork 20 rotates around the bottom fork shaft 21 and then compresses the damping unit 40, thereby achieving the effect of damping the shock.
According to the middle damping structure in the above embodiment, the first hangers are arranged on the frame below the seat, the second hangers are arranged on the hanger bent pipes, the hanger bent pipes are arranged above the rear wheel bottom fork, the front ends of the damping units are connected with the first hangers, the rear ends of the damping units are connected with the second hangers, and the connected damping units are located in the space below the seat of the frame and hidden in the space. Based on the structure, the first suspension loop is welded on the middle beam of the frame for the first time through the damping structure, and the space below the seat is enough, so that the damping can be hidden in the space below the frame seat. In addition, the shock absorption can also be chosen to be more comfortable.
Moreover, the hangers elbow still inclines towards the front end of the rear wheel bottom fork, so that the whole damping unit is also inclined forwards, and the damping angle of the whole damping structure is more suitable.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their full equivalents, the present application is intended to include such modifications and variations.
