Problems solved by technology

[0004] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a rear shock-absorbing structure of a large-displacement scooter, which has a simple structure and can solve the problem of poor stability and comfort caused by differences in the receiving force and acceleration of the rear wheels on both sides. It can also solve the problem of insufficient space and poor strength

Embodiment 1

[0021] Such as figure 2 As shown, the frame 1 is an inclined structure extending obliquely rearward and bent, and the rear shock absorber 2 is arranged laterally along the direction of the frame on the right side of the frame 1 (in other single shock absorber structures, it can also be arranged on the left side). side), a triangular connecting plate 4 is arranged on the side corresponding to the rear shock absorber 2 on the cradle 3, and the rear end of the rear shock absorber 2 is hinged on the triangular connecting plate 4, and a connecting rod is hinged on the triangular connecting plate 4 5. The lower end of the connecting rod 5 is hinged with one side of the motorcycle rear wheel train. The other side of the cradle 3 relative to the triangular connecting plate 4 is provided with a connecting lug 6, the connecting lug 6 is hingedly connected with a connecting rod 5, and the lower end of the connecting rod 5 is hinged with the other side of the rear wheel train of the moto...

Embodiment 2

[0023] Such as image 3 As shown, the frame structure is the same as that of Embodiment 1, the difference is that a rear shock absorber 2 is arranged on each side of the frame 1, and two triangular connecting plates 4 corresponding to the rear shock absorber 2 are provided on the cradle 3, and the cradle 3 The frame 3 is respectively hinged to the two connecting rods 5 through the two triangular connecting plates 4, and the lower ends of the two connecting rods 5 are respectively hinged to both sides of the rear wheel train of the motorcycle. This structure is a large-displacement scooter rear shock-absorbing structure that adopts double shock absorbers. It has two connecting rods and double supports for stability, and it is also beneficial to reduce the one-sided impact of the frame and reduce the impact on the cradle 3 at the same time. of torsional force.

[0024] Such as Figure 4 In the above-mentioned embodiment shown, a special design is made for the connection struct...

Abstract

The invention discloses a rear damping structure of a large-displacement pedal motorcycle, which comprises a frame and is characterized in that a rear shock absorber which is transversely arranged along the front-back direction of the frame is arranged below the left side or / and the right side of the frame, one end of the rear shock absorber is hinged with the front part of the frame, and a cradle is arranged at the rear part of the frame. The cradle is provided with a triangular connecting plate, the triangular connecting plate is hinged to the other end of the rear shock absorber, a connecting rod is further hinged to the triangular connecting plate, and the lower end of the connecting rod is hinged to a rear wheel train of the motorcycle. Wherein the projections of the frame connecting point A, the rear shock absorber connecting point B and the connecting rod connecting point C on the cradle in the same vertical plane parallel to the vehicle body are triangular. The structure has the beneficial effects that the stability of the whole vehicle is improved, the structure is beneficial to increasing the rear shock absorption compression stroke and improving the comfort of the whole vehicle, a single shock absorption structure can be adopted, the cost is reduced, and high strength is kept.

Description

technical field [0001] The invention relates to the field of motorcycles, in particular to a rear shock absorbing structure of a scooter with a large displacement. Background technique [0002] Motorcycle shock absorbers can alleviate the ups and downs, shocks and vibrations caused by the vehicle on various road conditions, making the driver and passengers more comfortable, stable and safe, so they are widely used. The front shock absorber of a motorcycle is usually set on the front fork, while the rear shock absorber of a motorcycle often adopts different structural settings according to different models. [0003] The arrangement of traditional scooter rear shock absorption is roughly divided into two types. One is that a small displacement motorcycle uses a single shock absorber to connect the wheel train and the frame. The use requirements of the model. But because shock absorption can only be arranged on one side (generally arranged on the left side), it has a great in...
