Abstract
The invention discloses a gearbox improvement structure for an electric vehicle, which comprises a gearbox, and a transmission shaft and an output shaft arranged on the gearbox. A driving gear is arranged on the transmission shaft; a driven gear which is engaged with the driving gear is arranged on the output shaft; the driven gear is connected on the output shaft in a sliding mode; and a clutch device which controls the driven gear and the driving gear to be disengaged and engaged is arranged on the gearbox. Because the clutch device which makes the driven gear to slide along a wheel axle so as to be disengaged from the driving gear is arranged on the gearbox, the electric vehicle gearbox improvement structure reduces the transmission resistance between gears during riding when the battery power is exhausted, and brings convenience to manual riding or pushing.
Description
Technical field
The present invention relates to a kind of gearbox improvement structure for electric vehicle.
Background technology
Electrical Bicycle be with electric energy such as storage battery, lithium celies as auxiliary energy, have two wheels, can realize that manpower is ridden, electronic or electric power-assist function.The prior electric car is transmission device usually with the gear.Like the patent No. is that 200820037837.3 Chinese utility model patent discloses a kind of gear transmission battery-driven car, and storage battery connects motor, and motor is installed on the vehicle frame, axletree connection gear, the transmission gear on the motor shaft and the coupling of the bonded assembly gear on the axletree.But this gear drive drains away manpower at battery power and rides or during go-cart, need to use bigger power overcome the resistance between gear.
Summary of the invention
Technical matters to be solved by this invention just provides a kind of manpower that when battery power exhausts, makes things convenient for and rides or the gearbox improvement structure for electric vehicle of go-cart.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: a kind of gearbox improvement structure for electric vehicle; Comprise gear case and be installed in transmission shaft and the output shaft on the said gear case, said transmission shaft is provided with driving gear, and said output shaft is provided with driven gear and driving gear engagement; It is characterized in that: said driven gear is slidingly connected on the said output shaft, and said gear case is provided with the control driven gear and driving gear breaks away from and the ingear arrangement of clutch.
As preferably, realize sliding block joint through spline fitted between said axletree and said driven gear.
As preferably, said arrangement of clutch comprises the rotary head of being located on the said gear housing sidewall, and rotary head rotates and promotes said driven gear and on axletree, slides and break away from driving gear, and said rotary head is by the handle control rotation in the gear case outside.
As preferably, said arrangement of clutch also comprises makes driven gear return the Bringing-back mechanism with said driving gear engage position.
As preferably, said Bringing-back mechanism is the retracing spring that is sheathed on the said axletree external diameter, and the axle on the said retracing spring one end apical grafting output shaft is used jump ring, said retracing spring other end apical grafting driven gear end face.
As preferably, the profile of said rotary head is the involute curve structure.The top of said handle is provided with crank, and said rotary head and handle are integral structure, adopts socket head cap screw fastening between said crank and the handle.
The present invention makes driven gear break away from the arrangement of clutch of driving gear along the axletree slip owing to adopted technique scheme, gear case to be provided with, thereby when battery power exhausts, rides and reduced the transmission resistance between gear, makes things convenient for manpower to ride or go-cart.
