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.Existing battery-driven car is transmission device usually with the gear.As 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, needs to use bigger power to overcome resistance between gear.
Summary of the invention
Technical matters to be solved by this invention just provides a kind of manpower that makes things convenient for and rides or the gearbox improvement structure for electric vehicle of go-cart when battery power exhausts.
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 output shaft on the described gear case, described transmission shaft is provided with driving gear, described output shaft is provided with driven gear and driving gear engagement, it is characterized in that: described driven gear is slidingly connected on the described output shaft, and described 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 by spline fitted between described axletree and described driven gear.
As preferably, described arrangement of clutch comprises the rotary head of being located on the described gear housing sidewall, and rotary head rotates and promotes described driven gear and slides on axletree and break away from driving gear, and described rotary head is by the handle control rotation in the gear case outside.
As preferably, described arrangement of clutch also comprises makes driven gear return Bringing-back mechanism with described driving gear engage position.
As preferably, described Bringing-back mechanism is the retracing spring that is sheathed on the described axletree external diameter, axle jump ring, described retracing spring other end apical grafting driven gear end face on the described retracing spring one end apical grafting output shaft.
As preferably, the profile of described rotary head is the involute curve structure.The top of described handle is provided with crank, and described rotary head and handle are integral structure, adopts socket head cap screw fastening between described crank and the handle.
The present invention breaks away from the arrangement of clutch of driving gear owing to adopted technique scheme, gear case to be provided with to make driven gear to slide along axletree, thereby when battery power exhausts, and rides and has reduced transmission resistance between gear, makes things convenient for manpower to ride or go-cart.
