Abstract
The invention provides an automatic transmission of an electric vehicle and relates to an automatic transmission of a pure electric vehicle. Under a normal situation, when a driving motor drives, a shifting gear box is in a high-speed operating state, namely that a motor input gear is meshed with a high-gear output gear, and a differential is in a high-speed working state and drives the electric vehicle to run; when in a situation that climbing or heavy load requires large torque, a gear selection motor is started by virtue of a controller and transmits a signal to a control system by virtue of a vehicle speed sensor I, a vehicle speed signal sensor II and a gear position signal sensor; and a shifting fork drives a shifting cam to separate the high-gear input gear, so that the motor input gear is switched to be meshed with a low-gear output gear, and thus the differential is enabled to be in a low-speed working state so as to drive the electric vehicle to run at a low speed. The automatic transmission has the beneficial effect of solving the problems that gear shifting can not be realized since faults occur to a gear shifting process due to long gear shifting time caused by manual operation of a shift lever.
Description
Technical field
The present invention relates to the automatic transmission of pure electric automobile.
Background technology
At present, the automatic transmission of pure electric automobile belongs to vacuum state at home substantially. E-AMT compares other wheel boxes, has the absolute market advantage. And the development of electromobile industry and policy guidance, also illustrate that the development prospect of E-AMT automatic transmission in future.
Having relevant research in electromobile many gearizations both at home and abroad, " OerlikonGraziano " company of Italy have developed two shift transmissions of coupling small-sized electric vehicle, and emulation shows can obviously reduce battery power consumption; At home, Beijing Institute of Technology develops 3 gear automatic mechanical transmissions (no-clutch) for the electronic passenger vehicle of Beijing Olympic, makes the economy of whole car improve 9%, and the pick-up period of 0��50km/h decreases 18%; Multi-shifting speed variator is by making traction electric machine be operated in desirable region the control of transmission system, thus improves the indexs such as the dynamic property of whole car, economy.
On the basis of the power truck of a employing fixed speed ratio speed reduction unit of certain motor corporation domestic, adopt two gear speed change transmission schemes, drive-motor has been carried out parameter matching design, devise the two-shift automatic speed variator of not band clutch coupling, formulate the shift control strategy taking motor Effec-tive Function as principle, carry out requiring as constraint taking whole car dynamic property to the speed ratio of transmission system, taking ECE(Eurocities economy) motor power consumes the minimum optimization design as target under state of cyclic operation, and the electromobile with employing fixed speed ratio speed reduction unit has carried out the contrast that ECE runs the energy consumption under circulating and continual mileage, result shows, whole car energy consumption reduces 6.6%, continual mileage extends 7.1%,
But with abundant fundamental research the difference is that, the industrialization of current electric car automatic speed transmission, does not also far reach the requirement meeting electromobile fast development. Pure electric automobile automatic transmission, in the application of whole car, also lags far behind the step of industry. Existing market there is no a maturation, can the pure electric automobile automatic transmission of scale operation.
Summary of the invention
It is an object of the invention to design a kind of novel low cost, lightweight, and the automatic speed derailleur for electric vehicle of more long life.
The technical scheme of the present invention is: a kind of automatic speed derailleur for electric vehicle is made up of right shell body, left shell, differential mechanism, output gear, high-grade output gear, low-grade output gear, high-grade input gear, low-grade input gear, gearshift tooth, gearshift pull bar, selector fork, gearshift spring, top tooth spring, gearshift cam, gear selecting motor shaft, gear selecting motor, gear selecting electric machine support and speed of a motor vehicle signal pick-off one, speed of a motor vehicle signal pick-off two, gear positions signal pick-off, it is characterised in that:
Under normal circumstances, when drive-motor drives, becoming shelves wheel casing and be in high speed running status, namely motor input gear engages with high-grade output gear, and variator is in high speed working order, drives power truck to run;
When running into climbing or heavy duty needs big torque, gear selecting motor is started by controller, gear selecting motor is by vehicle speed sensor one and speed of a motor vehicle signal pick-off two and gear positions signal pick-off, by signal transmission to Controlling System, drive gearshift cam by selector fork, top grade input gear is separated, motor input gear is switched to and engages with low-grade output gear, make variator be in slow running state, drive power truck to run at this slow speed.
The useful effect of the present invention:
The invention solves owing to by Shift lever manual operation, causing time, shift slow, change shelves handoff procedure breaks down and causes the problem that cannot become shelves.
After emulation result display adopts this automatic transmission, the drive-motor peak power of new coupling reduces 8.57%, and torque capacity reduces 8.5%; The dynamic property of two gear speed change automobiles of new coupling meets former vehicle design requirements, and 0��50km/h starting pick-up period decreases 0.26s, and max. speed improves 22.84km/h. And in economy, adopting two-shift automatic speed variator to make the energy consumption of whole car reduce 6.6%, continual mileage extends 7.1%. Employing two-shift automatic speed variator can be found out by emulation results contrast, motor can be made to be operated in efficient district more, when its reason adopts two shift transmissions, the operation torque of motor is more much smaller than adopting fixed stop speed reduction unit, this reduces the working current of motor, reduce the winding loss of motor, it is to increase the working efficiency of motor.
