Description

Motorcycle engine and frame connecting structure

Technical Field

The utility model relates to a motorcycle structural design field, concretely relates to motorcycle engine and frame connection structure.

Background

The motorcycle engine suspension structure is a mechanism for mounting a motorcycle engine on a motorcycle frame. Whether the structural design reasonably influences the vibration and impact strength in the driving process of the motorcycle or not is of great importance to the driving safety of the motorcycle. How to make the engine more simply and reasonably hung on the frame of the motorcycle is a hot area explored by the industry. The existing motorcycle engine is mainly connected with a frame through a front suspension point and a rear suspension point of the engine, the connection rigidity is not strong, the handling structure is unreasonable, the frame is easy to damage, meanwhile, the existing motorcycle structure frame is complex in design, the manufacturing cost is high, and the space occupied by the engine on the frame is large.

Disclosure of Invention

To the weak point among the above-mentioned prior art, the utility model provides a motorcycle engine and frame connection structure, its frame simple structure, rationally distributed has reduced the frame processing cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a motorcycle engine and frame connection structure, its characterized in that: the engine is located right below the frame, a first engine suspension point and a second engine suspension point are arranged on the frame, an engine suspension connected with the first engine suspension point is arranged at the cylinder head of the engine, an engine suspension connected with the second engine suspension point is arranged at the rear part of a gearbox of the engine, the frame group and the engine form a triangular structure after connection, a rear suspension mounting point is further arranged at the rear part of the gearbox of the engine, and the rear suspension system is connected with the rear suspension mounting point.

Further, the first and second engine suspension points are located on a lower main beam tube of the frame, and the first engine suspension point is located forward of the second engine suspension point.

Further, the rear suspension system comprises a rear bottom fork and a rear shock absorber, wherein the front end of the rear bottom fork is connected with the rear suspension mounting point, the lower end of the rear shock absorber is connected to the rear portion of the rear bottom fork, and the upper end of the rear shock absorber is connected to the rear portion of the frame.

The beneficial effects of the utility model include: the stress of the engine box body is fully utilized, the engine is used as one part of the frame, the frame structure is simpler, the cost is lower, and other parts are favorably arranged.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

A motorcycle engine and frame connection structure as shown in figure 1 comprises a frame 1, an engine 2 and a rear suspension system 3, wherein the engine 2 is positioned right below the frame 1. The frame 1 has a first engine suspension point 4 and a second engine suspension point 5 thereon. The cylinder head of the engine 2 is provided with an engine suspension A connected with a first engine suspension point 4, the rear part of the gearbox of the engine 2 is provided with an engine suspension B connected with a second engine suspension point 5, and the connected rear frame 1 group and the engine 2 form a triangular structure, namely the frame 1 and the engine 2 form a stable stressed structure. The rear part of the gearbox of the engine 2 is also provided with a rear suspension mounting point C, and the rear suspension system 3 is connected with the rear suspension mounting point C. Namely, the rear suspension system 3 depends on the strength bearing capacity of the gearbox body of the engine.

Further, the first and second

engine suspension points

4, 5 are located on the lower main beam tube of the frame 1, and the first engine suspension point 4 is located forward of the second engine suspension point 5. Therefore, the frame has simple structure, and the engine 2 and the frame 1 are reasonably arranged in space and have stable structure. Considering the impact of the vibration of the engine 2 on the frame 1, the strength problem is fully considered on the material selection of the lower main beam pipe of the frame 1, and the thickened pipe is generally adopted here, and two suspension points are reinforced.

As shown in fig. 1, the rear suspension system 3 includes a rear bottom fork 6 and a rear shock absorber 7, wherein the front end of the rear bottom fork 6 is connected to the rear suspension mounting point C, the lower end of the rear shock absorber 7 is connected to the rear portion of the rear bottom fork 6, and the upper end of the rear shock absorber 7 is connected to the rear portion of the frame 1. The engine 2 is fully utilized as a support, so that the structure of the frame 1 is reduced, and the frame processing cost is reduced.

The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
