Stretch setting, projection of the projection positioned at the central axes of stub on the ground of the central axes of the wheel mounting portion on the ground
Rear.Therefore, when electric bicycle is when turning to, view field of the vehicle on ground can be automatically biased towards the inside of bend, to
The center of gravity of people can be made to be located in the region of front wheels and rear wheels formation, further promote the stability of traveling.Therefore it can be by weight
Power realizes with gravity turn, and when steering is laborsaving, and it is handling good to ride.
In the stub suspension frame structure of above-mentioned electric bicycle, the central axes of the stub from the bottom to top to it is electronic from
The direction of advance of driving is obliquely installed.Therefore axle pin rearward rake, axle pin rearward rake can be such that vehicle vehicle frame in turning rolls inside tiltedly,
So as to offset the centrifugal force that electric bicycle is formed in turning, make the safer quick turning of vehicle.
In the stub suspension frame structure of above-mentioned electric bicycle, folder is formed between the central axes and ground of the stub
Angle α, and the angular range of angle α is：45 ° of 90 ° of < angle αs <.
In the stub suspension frame structure of above-mentioned electric bicycle, the both sides of the vehicle frame are respectively equipped with a suspension,
Stub is installed on each suspension respectively, is circumferentially rotated respectively on each stub and is connected with steering swing arm.Wheel, which is mounted on, to be turned to
In swing arm, the steering of wheel is realized in the rotation by turning to swing arm.
In the stub suspension frame structure of above-mentioned electric bicycle, the suspension includes mounting base, is set in mounting base
Have a upper cantilever and lower cantalever, one end of the upper cantilever and lower cantalever is connected with mounting base respectively, the other end respectively with stub
It is connected, buffer gear is equipped between the upper cantilever and lower cantalever.Buffer gear can not only improve comfort when driving,
And resilient support can be provided when turning to, the wheel positioned inside turn radius can ensure position when turning to after rack buffer
It can be bonded ground always in the wheel of outer turning radius, turning is safer.
In the stub suspension frame structure of above-mentioned electric bicycle, the buffer gear includes the upper of axial pivot bush unit
Bar and lower beam, the upper boom upper end are connected with upper cantilever, and the lower beam lower end is connected with lower cantalever, and the upper boom is under
Spring is equipped between bar, the spring one end acts on upper boom, and the other end acts on lower beam.When steering, it is located inside turn half
It mutually compresses, while spring-compressed, is realized with this slow between the lower beam on the upper boom and lower cantalever on upper cantilever on diameter wheel
Punching.
In the stub suspension frame structure of above-mentioned electric bicycle, the steering swing arm is fixed on stub by fastener
It puts on, stub set is rotationally sheathed on stub, and bearing is equipped between stub set and steering swing arm.

As shown in Figs 1-4, the stub suspension frame structure of this electric bicycle, including it is fixedly arranged on the suspension 2 of 1 side of vehicle frame,
It is installed with stub 3 on suspension 2, is circumferentially rotatably connected on stub 3 and turns to swing arm 4.It turns to swing arm 4 and is equipped with wheel mounting portion 5,
The central axes of wheel mounting portion 5 are laterally extended setting, and the projection of the central axes of wheel mounting portion 5 on the ground is positioned at stub 3
The rear of the projection of central axes on the ground, therefore, when electric bicycle is when turning to, view field of the vehicle on ground can be certainly
The dynamic inside for being biased to bend further promotes traveling so as to make the center of gravity of people be located in the region of front wheels and rear wheels formation
Stability.Therefore, it is possible to be realized with gravity turn by gravity, when steering, is laborsaving, and it is handling good to ride.
In the present embodiment, the central axes of stub 3 are obliquely installed to the direction of advance of electric bicycle from the bottom to top, therefore main
Pin 3 leans forward, and stub 3, which leans forward, can be such that vehicle vehicle frame 1 in turning rolls inside tiltedly, turn so as to offset electric bicycle
The centrifugal force formed when curved makes the safer quick turning of vehicle.
Further, angle α is formed between the central axes and ground of stub 3, and the angular range of angle α is：45 ° of < folders
90 ° of angle α <；The both sides of vehicle frame 1 are respectively equipped with a suspension 2, are installed with stub 3 on each suspension 2 respectively, on each stub 3
It circumferentially rotates to be connected with respectively and turns to swing arm 4, wheel, which is mounted on, to be turned in swing arm 4, and wheel is realized in the rotation by turning to swing arm 4
Steering.Suspension 2 includes mounting base 6, is equipped with upper cantilever 7 and lower cantalever 8 in mounting base 6, and the one of upper cantilever 7 and lower cantalever 8
End is connected with mounting base 6 respectively, and the other end is connected with stub 3 respectively, and buffer gear 9 is equipped between upper cantilever 7 and lower cantalever 8,
Buffer gear 9 can not only improve comfort when driving, and can provide resilient support when turning to, and be located inside turn half
The wheel of diameter can ensure that the wheel positioned at outer turning radius can be bonded ground always when turning to after rack buffer, turning is more
Add safety.
Specifically, buffer gear 9 includes the upper boom 10 and lower beam 11 of axial pivot bush unit, 10 upper end of upper boom and upper cantilever 7
It is connected, 11 lower end of lower beam is connected with lower cantalever 8, spring 12 is equipped between upper boom 10 and lower beam 11,12 one end of spring acts on
Bar 10, the other end act on lower beam 11, when steering, are located at upper boom 10 on the upper cantilever 7 on inside turn radius wheel and lower outstanding
It is mutually compressed between lower beam 11 on arm 8, while spring 12 compresses, and buffering is realized with this.It is solid by fastener to turn to swing arm 4
It is scheduled on stub set 13, stub set 13 is rotationally sheathed on stub 3, and axis is equipped between stub set 13 and steering swing arm 4
It holds.
Further, the central axes of stub 3 are obliquely installed to 1 outside of vehicle frame from the bottom to top respectively, and two stubs 3 are in eight
Font arranges that the central axes of stub 3 are obliquely installed to 1 outside of vehicle frame from the bottom to top respectively, and two stubs 3 are in inverse Ba type cloth
It sets, therefore stub 3 slopes inwardly, when wheel is turned round around stub 3, the minimum point of tire will be less than ground level, and according to anti-
Active force, ground is harder than wheel, so vehicle frame 1 can moderately be jacked up because of stress, and when wheel returns timing, this power meeting
It is released, to which auxiliary wheel returns just, in addition, other than this effect, 3 introversion of stub can also prolong because of 3 axis of stub
The point that long line intersects with road surface contacts Distance Shortened of that point on ground with wheel, to make the steering arm of force increase, allows steering
It is lighter.In addition, turning to braking mechanism 14 is installed in swing arm 4.
