Description

Technical Field

[0001] The utility model relates to the field of rear shock absorber and engine installation, in particular to a motorcycle rear shock absorber mounting bracket Background Art

[0002] Currently, the rear shock absorber of most motorcycles is directly connected to the mounting point on the engine (such as a 200cc displacement). Therefore, the location of the shock absorber mounting point is taken into account when designing the engine's external structure. However, if a motorcycle needs to replace the engine with a larger displacement, such as a 300cc engine, the external structure of the 300cc engine is different from that of the 200cc engine, and the location of the rear shock absorber mounting point will also be inconsistent. This will cause the rear shock absorber to not fit properly with the replaced engine. Therefore, it is necessary to design a mounting bracket to achieve a reliable connection when the rear shock absorber and engine cannot be properly assembled. Utility Model Content

[0003] Purpose of the utility model: The purpose of the utility model is to provide a motorcycle rear shock absorber mounting bracket, which can achieve a reliable connection between the rear shock absorber and the engine when the mounting points on the shock absorber and the engine cannot be normally assembled.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a motorcycle rear shock absorber mounting bracket, which is used to fix the shock absorber on multiple mounting points of the engine, including a left branch fixedly connected to the shock absorber, a lower branch fixedly connected to the main force mounting point of the engine, and a right branch fixedly connected to the secondary force mounting point of the engine. Each branch is provided with a hole for connecting to the corresponding mounting point.

[0005] Wherein, the mounting bracket is an integrated structure formed by die-casting of aluminum alloy material.

[0006] Among them, reinforcing ribs are provided between the lower branch and the left branch.

[0007] Wherein, the hole position of the lower branch is a threaded hole.

[0008] Wherein, the holes of the left branch and the right branch are through holes.

[0009] Wherein, a bearing is fixed in the through hole of the left branch, and the rear shock absorber is fixedly connected to the inner ring of the bearing.

[0010] Wherein, the bottom end of the rear shock absorber is a U-shaped frame with mounting ears, and the mounting ears of the U-shaped frame are fixed to the inner ring of the bearing by screws.

[0011] Beneficial effects: The utility model has the following advantages: 1. The mounting bracket has a simple structure, is easy to process and assemble, and has good structural strength; 2. The mounting bracket is designed as a whole to fit the shape of the engine surface, ensuring a stable connection with the mounting bracket and the engine, while reducing the space occupied by the bracket; 3. The mounting bracket serves as a connecting device between the rear shock absorber and the engine, realizing a reliable connection between the rear shock absorber and the engine.

[0016] The technical solution of the present utility model is described in detail below with reference to the embodiments and drawings.

[0017] like Figure 1-4 As shown, engine 3 has three mounting points: mounting point 1, mounting point 2, and mounting point 3. Mounting point 3 is located to the lower left of mounting point 1 and mounting point 2, and they are located on the same vertical plane. Mounting bracket 1, which connects rear shock absorber 2 to engine 3, has fixing holes (holes 1, 2, and 3) that match the positions of these three mounting points, thereby securing mounting bracket 1 to engine 3. The upper end of mounting bracket 1 has a fourth hole that connects to the lower end of rear shock absorber 2, allowing rear shock absorber 2 to be rotatably connected to mounting bracket 1.

[0018] Because the surface morphology between the three mounting points of the engine 3 is irregular, the mounting bracket 1 is designed to fit the surface of the engine 3, ensuring a stable connection between the mounting bracket 1 and the engine 3 while reducing the space occupied by the bracket. To further reduce the space occupied by the mounting bracket 1, the fourth hole is located above the third hole and to the left of the first and second holes. The specific structure of the mounting bracket 1 is as follows: Figure 1-2As shown, it includes three branches: a lower branch 1.1, a left branch 1.2, and a right branch 1.3. The lower branch has a third hole corresponding to the mounting point 3 of the engine 3, the left branch 1.2 has a fourth hole corresponding to the bottom mounting position of the rear shock absorber 2, and the right branch 1.3 has a first hole and a second hole corresponding to the mounting points 1 and 2 of the engine 3. The first hole is a waist-shaped hole, the second hole is a round through hole, and the third hole is a threaded hole. When mounting to the mounting point of the engine 3, a bolt or screw passes through the corresponding mounting point of the engine 3 and is fixed to the corresponding hole of the mounting bracket 1.

[0019] The fourth hole is also a circular through-hole, in which a bearing is installed. The bottom end of the rear shock absorber 2 is a U-shaped frame with mounting ears. The mounting ears of the U-shaped frame are located on both sides of the left branch 1.2, corresponding to the inner ring of the bearing in the fourth hole. A screw is used to pass through the U-shaped frame and the inner ring of the bearing to fix the two together, thereby realizing the rotational connection of the rear shock absorber 2 to the left branch 1.2 of the mounting bracket 1.

[0020] The mounting bracket 1 can be die-casted from an aluminum alloy material. The aluminum alloy material has high strength and is easy to process, which makes the assembly process simple and the installation reliable and firm, thereby ensuring the structural strength of the entire vehicle. According to the force direction of the rear shock absorber 2, the engine 3 mounting point 3 is determined as the main force point, and the other two mounting points 1 and 2 are secondary force points. Therefore, in order to ensure that the mounting bracket 1 does not deform or break when subjected to the maximum force, some reinforcing ribs can be added in the force direction of the mounting bracket 1 to improve the rigidity and strength of the mounting bracket 1, thereby ensuring the safety of the entire vehicle.

[0021] The mounting bracket 1 of this embodiment is suitable for a 300cc displacement engine 3. By adjusting the distribution of the holes of the mounting bracket 1, it can be adapted to other types of engine mounting points.
