Abstract
An improved electric bicycle front fork structure comprises a front fork and a motor. A motor shaft is matched with a front fork hook. The radius of the circular arc of the front fork hook is 6mm. The improved electric bicycle front fork structure solves the problem that the motor gets loose because of non-uniform stress of the front fork hook caused by poor matching and accordingly a whole unit cannot work normally.
Description
Technical field:
The utility model relates to the bicycle field, particularly relates to a kind of improved Electrical Bicycle front fork structure.
Background technology:
Electrical Bicycle be with storage battery as auxiliary energy, have two wheels, can realize that manpower is ridden, the extraordinary bicycle of electronic or electric power-assist function.It is on the basis of ordinary bicycle, and the Personal Transporter of the electromechanical integration of control member such as motor, controller, storage battery, handle brake lever and display instrument system has been installed.Motor is installed on the front fork; It is that the cooperation external diameter is 10 millimeters a threaded shaft that the front fork of prior art colludes pawl; And the external diameter of motor shaft is 12 millimeters, and motor is with when front fork cooperates, can occur motor shaft can not be fully and the front fork inboard of colluding pawl fit tightly together.Cause front fork to collude the pawl discontinuity, of long duration motor can to occur loosening, influences the normal operation of car load.Therefore, be necessary to improve.
The utility model content:
The goal of the invention of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of Electrical Bicycle front fork structure that can closely cooperate and guarantee the normal operation of car load with motor shaft is provided.
For realizing the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of improved Electrical Bicycle front fork structure comprises front fork and motor, and wherein, motor shaft and front fork collude pawl and be combined together, and the arc radius that said front fork colludes pawl is 6 millimeters.
The utility model has following advantage with respect to prior art:
The utility model is because the arc radius that colludes pawl to front fork has made 6 millimeters into by original 5 millimeters; Make motor shaft can fit tightly the inboard of colluding pawl at front fork fully when front fork colludes pawl and cooperates; Solved because of cooperating not tight effectively; It is loosening to make front fork collude the motor that the pawl discontinuity causes, thereby influences the problem of the normal operation of complete machine.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to Fig. 1, according to a kind of improved Electrical Bicycle front fork structure that the utility model provides, comprise front fork 1 and motor shaft 2, wherein, motor shaft 2 colludes pawl 3 with front fork and is combined together, and the arc radius that front fork colludes pawl 4 is 6 millimeters.
Claims (1)
1. an improved Electrical Bicycle front fork structure comprises front fork and motor shaft, and wherein, motor shaft and front fork collude pawl and be combined together, and it is characterized in that: the arc radius that said front fork colludes pawl is 6 millimeters.
