Description
Technical field
The utility model relates to technical field of motorcycles, especially a kind of motorcycle rear fork structure.
Background technique
Motorcycle is a kind of common vehicles, is adapted to city and rural road, therefore by vast
Bicyclist's likes.Motorcycle rear fork is the important component of motorcycle, is used for rear wheel of motorcycle and frame of motorcycle
Connection.Existing motorcycle rear fork generallys use unilateral single tube structure, and structural strength is lower, and motorcycle is bent in high speed
When, rear chain stay rear end is easy to produce biggish deformation by biggish torsion and causes danger.
Utility model content
In order to overcome the shortcomings of existing motorcycle rear fork structure, the utility model provides that a kind of intensity is high, bends more
The motorcycle rear fork structure of safety.
To achieve the goals above, the utility model one embodiment the technical solution adopted is that:
A kind of motorcycle rear fork structure, including two groups of pipe groups being symmetrical set, every group of Guan Zujun includes up and down
The upper branch pipe and lower-left breeches pipe of distribution, are connected with the first support tube between the upper branch pipe and lower-left breeches pipe, two upper branch pipe front ends it
Between be provided with transverse connecting pipe, transverse connecting pipe both ends are connect with the front end of two lower-left breeches pipes respectively, the setting of the front end of lower-left breeches pipe
There is the connection terminal connecting with vehicle frame, upper branch pipe rear end is connected with lower-left breeches pipe rear end by fixed plate.
Further, the second support tube is connected between two upper branch pipes.
Further, outward bending forms bending position in the middle part of two upper branch pipes, and second support tube is connected to two
Between the bending position of upper branch pipe.
Further, web is connected between two lower-left breeches pipes.
Further, the two sides of the web are provided with securing plate.
One or more embodiments of the utility model at least have the advantages that the motorcycle rear fork knot
Structure, including two groups of pipe groups being symmetrical set, every group of Guan Zujun includes the upper branch pipe being distributed up and down and lower-left breeches pipe, thus shape
The first support tube is connected at unilateral double pipe structure, while between upper branch pipe and lower-left breeches pipe to constitute woven structure, significantly
The intensity of the rear bottom fork structure is improved, and by being provided with transverse connecting pipe, transverse connecting pipe between two upper branch pipe front ends
Both ends are connect with the front end of two lower-left breeches pipes respectively, thus when motorcycle high speed is bent, torsion that rear chain stay rear end is subject to
It is preferably transferred to rear chain stay front end, and then torsion is transferred on vehicle frame connected to it by rear chain stay front end, so that after
Chain stay stress is more firm, and the rear bottom fork structure makes that stress point is more, forced area is bigger using woven structure, thus
When motorcycle high speed is bent, deformation is smaller, bends safer, smooth.
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 rear fork structure, including bilateral symmetry
Two groups of pipe groups being arranged, every group of Guan Zujun include the upper branch pipe 1 being distributed up and down and lower-left breeches pipe 2, the upper branch pipe 1 and lower-left breeches pipe
The first support tube 3 is connected between 2, the quantity of the first support tube 3 can according to need and be arranged, the caliber of the first support tube 3
Preferably smaller than upper branch pipe 1 and the caliber of lower-left breeches pipe 2 are provided with transverse connecting pipe 11, lateral connection between two 1 front ends of upper branch pipe
11 both ends of pipe are connect with the front end of two lower-left breeches pipes 2 respectively, and the front end of lower-left breeches pipe 2 is provided with the connection terminal connecting with vehicle frame
21,1 rear end of upper branch pipe and 2 rear end of lower-left breeches pipe are connected by fixed plate 5.
The motorcycle rear fork structure, including two groups of pipe groups being symmetrical set, every group of Guan Zujun includes to divide up and down
The upper branch pipe 1 and lower-left breeches pipe 2 of cloth, to form unilateral double pipe structure, while being connected with first between upper branch pipe 1 and lower-left breeches pipe 2
Support tube 3 greatly improves the intensity of the rear bottom fork structure, and between two 1 front ends of upper branch pipe to constitute woven structure
By being provided with transverse connecting pipe 11,11 both ends of transverse connecting pipe are connect with the front end of two lower-left breeches pipes 2 respectively, thus in motor
When overall height ram compression is curved, the torsion that rear chain stay rear end is subject to preferably is transferred to rear chain stay front end, and then rear chain stay front end will be turned round
Power is transferred on vehicle frame connected to it, so that rear chain stay stress is more firm, and the rear bottom fork structure uses Weaving type
Structure makes that stress point is more, forced area is bigger, so that deformation is smaller when motorcycle high speed is bent, bends safer, suitable
Freely.
Preferably, it is connected with the second support tube 4 between two upper branch pipes 1, by being provided with the second support tube 4, made
Bonding strength is higher between two upper branch pipes 1, be conducive to improve it is entire after chain stay structural strength.
Preferably, two upper branch pipes, the 1 middle part outward bending forms bending position 12, by outward bending to formed compared with
The rear wheels structure of big space motorcycle, since bending position 12 is the weak spot of structural strength, the second support tube
4 are connected between the bending position 12 of two upper branch pipes 1, and certainly, the second support tube 4 can have more, in addition to being connected on two
The other positions of two upper branch pipes 1 are also connected between the bending position 12 of breeches pipe 1.
Preferably, it is connected with web 6 between two lower-left breeches pipes 2, is improved under two by being provided with web 6
Bonding strength between breeches pipe 5 is conducive to the structural strength for improving entire rear chain stay, while can be set and being convenient on web 6
The mounting hole of other assemblies is installed.
In above-mentioned technical proposal, the two sides of the web 6 are also provided with securing plate 7, by be provided with securing plate 7 from
And it can reinforce to lower-left breeches pipe 2 and then further fixing.
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.
