Description
Technical field
This utility model relates to the automatic transmission of pure electric automobile.
Background technology
At present, the automatic transmission of pure electric automobile the most substantially belongs to vacuum state.E-AMT compares other change speed gear boxes, has the absolute market advantage.And the development of electric automobile industry and policy guidance, also illustrate that E-AMT automatic transmission is in following development prospect.
Having relevant research, " Oerlikon Graziano " company of Italy to have developed two shift transmissions of coupling small-sized electric vehicle at electric automobile many gearizations aspect both at home and abroad, emulation shows can substantially reduce battery power consumption；At home, Beijing Institute of Technology develops 3 gear automatic mechanical transmissions (no-clutch) for Beijing Olympic electric motor coach, makes the economy of car load improve 9%, and the acceleration time of 0～50km/h decreases 18%；Multi-shifting speed variator by making traction electric machine be operated in preferable region to the control of drive system, thus improves the indexs such as the dynamic property of car load, economy.
On the basis of the electric motor car of a employing fixed speed ratio decelerator of certain motor corporation domestic, use two gear gear schemes, parameter matched design has been carried out to driving motor, devise the two-shift automatic speed variator without clutch, formulate the shift control strategy with motor Effec-tive Function as principle, carry out requiring as constraint with car load dynamic property to the speed ratio of drive system, with ECE(Eurocities economy) motor power consumes the optimization design of minimum target under state of cyclic operation, and carried out the energy consumption under ECE operation circulation and the contrast of continual mileage with the electric automobile using fixed speed ratio decelerator, result shows, car load energy consumption reduces 6.6%, continual mileage extends 7.1%；
But unlike abundant fundamental research, the industrialization of current electric car automatic speed transmission, also it is far from reaching the requirement meeting electric automobile fast development.Pure electric automobile automatic transmission, on car load is applied, also lags far behind the step of industry.There is no a maturation, the pure electric automobile automatic transmission of energy large-scale production in the market.
Summary of the invention
The purpose of this utility model is design a kind of novel low cost, lightweight, and the automatic speed derailleur for electric vehicle of more long life.
The technical solution of the utility model is: a kind of automatic speed derailleur for electric vehicle is made up of right shell body, left shell, differential mechanism, output gear, high gear output gear, low gear output gear, high gear input gear, low gear input gear, gearshift tooth, gearshift pull bar, selector fork, gearshift spring, apical tooth spring, shifting cam, block selecting motor shaft, block selecting motor, block selecting electric machine support and GES sensor one, GES sensor two, gear positions signal transducer, it is characterised in that:
Under normal circumstances, when driving motor to drive, variable block gear-box is in high-speed cruising state, i.e. motor input gear and engages with high gear output gear, and variator is in high speed operation state, drives electric motor car to run；
When running into climbing or heavy duty needs big torque, block selecting motor is started by controller, block selecting motor is by vehicle speed sensor one and GES sensor two and gear positions signal transducer, signal is passed to control system, drive shifting cam by selector fork, high gear input gear is separated, makes motor input gear be switched to low gear output gear and engage, make variator be in tick-over state, drive electric motor car to run at this slow speed.
The beneficial effects of the utility model:
This utility model solves due to by gear shifting rod manual operation, causes the variable block time slow, and variable block handoff procedure breaks down, and cause cannot the problem of variable block.
After simulation result display uses this automatic transmission, the driving motor peak power of new coupling reduces 8.57%, and torque capacity reduces 8.5%；The dynamic property of two gear transmission cars of new coupling meets the design requirement of former vehicle, and 0～50km/h pickup time decreases 0.26s, and max. speed improves 22.84km/h.And in economy, using two-shift automatic speed variator to make the energy consumption of car load reduce 6.6%, continual mileage extends 7.1%.Compared by simulation result and can be seen that employing two-shift automatic speed variator, motor can be made to be operated in efficient district more, when its reason is to use two shift transmissions, the operation torque of motor is more much smaller than using fixing gear decelerator, this reduces the operating current of motor, reduce the winding loss of motor, improve the work efficiency of motor.
