Description
Technical field
The utility model relates to technical field of motorcycles, especially a kind of motorcycle frame structure.
Background technique
Motorcycle is a kind of common vehicles, is adapted to city and rural road, therefore by vast
Bicyclist's likes.Frame of motorcycle is the main component of motorcycle, carry in entire motorcycle the support of each component and
Positioning especially positions the support of engine.Existing frame of motorcycle girder generallys use mono-tube design, although can
Entire vehicle frame is supported, but its intensity is lower, poor to the support positioning of engine, engine output is unstable, vibrates larger.
Utility model content
In order to overcome the shortcomings of existing motorcycle frame structure, it is high, with small vibration that the utility model provides a kind of intensity
Motorcycle frame structure.
To achieve the goals above, the utility model one embodiment the technical solution adopted is that:
A kind of motorcycle frame structure, including vehicle frame main beam, the vehicle frame back rest and seat tube, the vehicle frame main beam both ends point
Other connecting vehicle frame standpipe and the vehicle frame back rest, vehicle frame main beam include two groups of supervisor's groups being symmetrical set, and every group of supervisor's group is equal
Including the top tube and down tube being distributed up and down, support tube is connected between the top tube and down tube, the upper tube of two groups of supervisors group is by vehicle
It erects and is inclined outwardly to form upper tube angle at pipe, the down tube of two groups of supervisors group is inclined outwardly by seat tube forms lower tube clip
Angle, the down tube angle are greater than upper tube angle.
Further, the support tube is provided with a plurality of, and angle is acute angle between adjacent supports pipe.
Further, the upper tube has been bent to form upper tube bending position and and vehicle frame from after being inclined outwardly at seat tube under
Back rest connection.
Further, the down tube bends inwards after being inclined outwardly by seat tube is formed with down tube bending position and and upper tube
Connection.
Further, support tube is connected between the upper tube bending position and down tube bending position.
One or more embodiments of the utility model at least have the advantages that the motorcycle frame structure
Vehicle frame main beam includes two groups of supervisor's groups being symmetrical set, and every group of supervisor's group includes the top tube and down tube being distributed up and down,
Support tube is connected between top tube and down tube so that vehicle frame main beam forms unilateral double pipe structure, while it is two-tube between use
Support tube connection greatly improves the intensity of vehicle frame to constitute Weaving type vehicle frame, in addition, the upper tube of two groups of supervisors group is stood by vehicle frame
It being inclined outwardly to form upper tube angle at pipe, the down tube of two groups of supervisors group is inclined outwardly by seat tube forms down tube angle, under
Pipe clamp angle is greater than upper tube angle, and upper tube angle is smaller so that vehicle mechanics concentration, can be improved vehicle frame strength, down tube angle
It is larger to alloing vehicle frame main beam is stronger to encase engine, keep engine output more stable, vibrate smaller.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of one embodiment of the utility model；
Fig. 2 is another angle schematic diagram of Fig. 1.
Specific embodiment
Referring to attached drawing 1-2, one embodiment of the utility model, a kind of motorcycle frame structure, including vehicle frame main beam, vehicle
The frame back rest 2 and seat tube 1, the vehicle frame main beam both ends are separately connected seat tube 1 and the vehicle frame back rest 2, and vehicle frame main beam includes
There are two groups of supervisor's groups being symmetrical set, every group of supervisor's group includes the upper tube 3 and down tube 4 being distributed up and down, 3 He of upper tube
Support tube 5 is connected between down tube 4, the caliber of support tube 5 is preferably smaller than the caliber of upper tube 3 and down tube 4, what two groups of supervisors organized
Upper tube 3 is inclined outwardly by seat tube 1 forms upper tube angle, and the down tube 4 of two groups of supervisors group is inclined outwardly by seat tube 1
Down tube angle is formed, the down tube angle is greater than upper tube angle.
The vehicle frame main beam of the motorcycle frame structure includes two groups of supervisor's groups being symmetrical set, and every group of supervisor's group is equal
Including the upper tube 3 and down tube 4 being distributed up and down, support tube 5 is connected between upper tube 3 and down tube 4, so that vehicle frame main beam shape
At unilateral double pipe structure, at the same it is two-tube between connect to constitute Weaving type vehicle frame using support tube 5, greatly improve the strong of vehicle frame
Degree, in addition, the upper tube 3 of two groups of supervisors group is inclined outwardly by seat tube 1 and forms upper tube angle, the down tube 4 of two groups of supervisors group
It is inclined outwardly by seat tube 1 and forms down tube angle, down tube angle is greater than upper tube angle, and upper tube angle is smaller so that vehicle power
It learns and concentrates, vehicle frame strength can be improved, down tube angle is larger to allow vehicle frame main beam is stronger to encase engine,
Keep engine output more stable, vibrates smaller.
Preferably, the support tube 5 is provided with a plurality of, and angle is acute angle between adjacent supports pipe 5, so that upper tube 3
Tie point between down tube 4 is more more, and angle is acute angle to constitute triangular structure between adjacent supports pipe 5, can
To play the role of better bracing reinforcement, the intensity of vehicle frame is further increased.
Preferably, the upper tube 3 be bent to form from after being inclined outwardly at seat tube 1 under upper tube bending position 31 and with
The vehicle frame back rest 2 connects, and upper tube 3 is preferably connected and fixed with the vehicle frame back rest 2.
Preferably, the down tube 4 bend inwards after being inclined outwardly by seat tube 1 be formed with down tube bending position 41 and with
Upper tube 3 connects, so as to preferably adapt to the shape of engine and then encase positioning to engine progress is stronger.
Preferably, support tube 5 includes at least the support tube 5 being located between upper tube bending position 31 and down tube bending position 41, from
And position 31 and the realization reinforcement fixation of down tube bending position 41 are bent to upper tube, be conducive to improve frame strength.
The preferred embodiment of above only the utility model, the utility model are not limited to above embodiment,
As long as its technical effect for reaching the utility model with identical means, all should belong to the protection scope of the utility model.
