Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model includes vehicle frame 1, the two-wheel Shock-absorbing fork 2 set on vehicle frame front end and/or rear end, even
It is connected to the wheel 3 and drive mechanism for wheel of two-wheel Shock-absorbing fork, wherein
The two-wheel Shock-absorbing fork includes that the fork of top vehicle 4 connecting with vehicle frame and two are respectively arranged on top fork two sides bottom
The lower part fork 5 at end, the lower part fork are equipped with wheel, and lower part fork top is connected with shock bracket 6, and shock bracket is located at
It top fork bottom end side and is connect between the fork bottom end of top by damping spring 7；
The drive mechanism for wheel includes the driving motor 8 for being fixed on top fork, and the driving motor passes through transmission dress
It sets and the wheel for being installed on two side lower part forks is driven to rotate synchronously.
Two-wheel Shock-absorbing fork can be set to front fork position, rear fork position according to the needs of use or be arranged jointly in front and rear fork；
If selecting two-wheel Shock-absorbing fork in front fork position, rear fork position can install known existing wheel；If being selected in rear fork position
With two-wheel Shock-absorbing fork, then front fork position can install known existing wheel；
Top fork has bigger separation distance compared to traditional fork between the breeches pipe of two sides；Lower part fork is then
It is identical as existing fork structure, it directly installs and connects with wheel, the shock bracket on lower part fork top is used for support damping
Spring is connected by damping spring between the lower part fork and top fork of two sides, the spring cooperation two-wheel support of bilateral, tool
There is better stability；
It can also be cooperated with the use of traditional driving structure double using the electronic vehicle of calling oneself of two-wheel Shock-absorbing fork
It takes turns and drive mechanism for wheel is set at Shock-absorbing fork；
Driving motor selects differential speed motor, and differential speed motor is fixed on top fork, the transmission device packet by hanger 9
The drive sprocket 10 for being connected to the output shaft both ends of differential speed motor is included, is connected respectively with the wheel shaft of the wheel of two side lower part forks inside
The driven sprocket 11 that connects and the driving chain 12 for successively bypassing drive sprocket and driven sprocket.
Driving motor is fixed on top fork by hanger, and drives two wheel synchronous rotaries by transmission device,
With stronger driving stability.
Preferably, the output shaft both ends of the differential speed motor are aligned the company of two damping springs and shock bracket top respectively
Contact.Differential speed motor can also be fixed to achieve a fixed connection with lower part fork, output shaft and the lower part fork of differential speed motor, so that
Differential speed motor is relatively fixed with wheel, but also the position of drive sprocket and driven sprocket is fixed to each other, passes convenient for transmission device
