The utility model proposes a motorcycle frame, including the upper left main beam tube and the upper right main beam tube, the left upper main beam tube, the right upper main beam tube and the standpipe are welded and connected, the rear section of the left upper main beam tube and the right upper main beam tube rear section A U-shaped shock absorbing support pipe is provided to connect with the upper left tailpipe and the upper right tailpipe respectively, and the bending connection of the front part of the upper left tailpipe and the upper right tailpipe is flat, and the upper suspension bracket of the engine adopts a movable connection with the engine. The beneficial technical effect of the motorcycle frame of the utility model is that the suspension installation method of the movable engine is used, the installation of the engine is simple and convenient, and the applicability is strong. Engines with different installation structures can be installed to improve the comfort of the whole vehicle. The tailpipe adopts bending The flattening is connected with the U-shaped shock-absorbing support pipe to improve the rigidity and strength of the vehicle frame.

Description

A motorcycle frame

technical field

The utility model relates to the field of motorcycles, in particular to a motorcycle frame.

Background technique

The frame of the motorcycle in the prior art is mainly connected with the main beam tube through the standpipe, and then connected with the tail pipe through the middle and rear section of the main beam tube. An upper suspension bracket is arranged on the upper suspension plate, and the upper suspension bracket is fixedly connected with the engine. Although the structure of this cloth cover is simple, once the engine vibrates with this arrangement, the force transmitted to the frame through the hard connection will be greater. Large, which affects the comfort, and it is easy to cause excessive fatigue of the frame, resulting in frame breakage. Apparently, the motorcycle frame of the prior art has a hard connection, and the force transmitted to the frame will be greater, thereby affecting the comfort, and easily causing excessive fatigue of the frame, leading to problems such as frame breakage.

Contents of the invention

In order to solve the problem that the hard connection existing in the motorcycle frame of the prior art will transmit more force to the frame, thereby affecting the comfort, it is also easy to cause excessive fatigue of the frame, leading to problems such as frame breakage. The utility model provides a motorcycle frame.

The motorcycle frame of the utility model comprises a left upper main beam tube and a right upper main beam tube. The rear section of the main beam tube is provided with a U-shaped shock-absorbing support pipe which is respectively connected with the left upper tail pipe and the right upper tail pipe.

A further technical solution is that the bending connection of the front section of the left upper tail pipe and the right upper tail pipe is flat.

A further technical solution is that the upper suspension bracket of the engine is movably connected with the engine.

The beneficial technical effect of the motorcycle frame of the utility model is that the hanging installation method of the movable engine is used, the installation of the engine is simple and convenient, the applicability is strong, the engine of different installation structures can be installed, and the comfort of the whole vehicle is improved, and the tailpipe adopts bending The flattening is connected with the U-shaped shock-absorbing support pipe to improve the rigidity and strength of the vehicle frame.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model motorcycle frame.

Below in conjunction with accompanying drawing and specific embodiment, the motorcycle frame of the utility model is further described.

detailed description

Accompanying drawing 1 is the structure schematic diagram of motorcycle frame of the present invention, among the figure, 1 is standpipe, 2 is upper left main beam tube, 3 is upper right main beam tube, 4 is suspension plate on engine, 5 is U-shaped damping support Pipe, 6 is the upper left tail pipe, 7 is the upper right tail pipe, 8 is the upper suspension bracket, and 9 is the flat place of the upper left tail pipe. As can be seen from the figure, the motorcycle frame of the present invention includes the upper left main beam tube 2 and the upper right main beam tube 3, the upper left main beam tube 2, the upper right main beam tube 3 are welded to the standpipe 1, the upper left main beam tube The rear section of the tube and the rear section of the upper right main beam tube are provided with U-shaped damping support tubes 5 which are respectively connected with the upper left tail pipe 6 and the upper right tail pipe 7 . The left upper tail pipe 6 and the upper right tail pipe 7 are flat in shape at the front section bending connection. The suspension bracket 8 on the engine is movably connected with the engine. In the utility model, the flat structure at the bending joint of the upper left tail pipe 6 and the upper right tail pipe 7 has a large contact surface with the U-shaped damping support pipe 5, so that after welding, the strength and rigidity of the vehicle frame are further improved. The engine upper suspension bracket 8 is movable connected with the engine, and the engine upper suspension bracket 8 can be adjusted. During assembly, it is convenient and quick to change, and the requirements for the engine installation holes are reduced, the technical requirements are reduced, and the production efficiency is improved.

The beneficial technical effect of the motorcycle frame of the utility model is that the hanging installation method of the movable engine is used, the installation of the engine is simple and convenient, the applicability is strong, the engine of different installation structures can be installed, and the comfort of the whole vehicle is improved, and the tailpipe adopts bending The flattening is connected with the U-shaped shock-absorbing support pipe to improve the rigidity and strength of the vehicle frame.

Although the utility model has been described herein with reference to an illustrative embodiment of the utility model, it should be understood that those skilled in the art can devise many other modifications and implementations which will fall within the scope of the disclosure of this application. within the scope and spirit of the principles. More specifically, within the scope of the disclosure, drawings and claims of the present application, various modifications and improvements can be made to the components and/or layout of the subject combination layout. In addition to modifications and improvements in component parts and/or layout, other uses will be apparent to those skilled in the art.
