The specific embodiment
Now be described further in conjunction with the accompanying drawings.
The present invention is by electrical motor 1, connector 4, and sleeve 5 and automatic machincal transmission are formed.Automatic machincal transmission is made up of change-speed box 8, actuating unit 10 and electronic control unit 11.Motor output shaft 2 and input shaft 7 all are processed with spline, and diaxon connects by inner spline sleeve 5, and the outputting power of electrical motor imports change-speed box 8 into by motor output shaft 2, sleeve 5, input shaft 7.Connector 4 is used to connect the housing of electrical motor 1 and the housing of change-speed box 8, and its two ends are fixed on the end face of electrical motor 1 and change-speed box 8 housings respectively by bolt 3 and 6.Change-speed box 8 has four gears, and the transmitting ratio of its I retaining, II retaining, III retaining, IV retaining is followed successively by 4.41,2.45,1.48,1, alternating-current motor/AC motor or DC motor all can with its coupling.When adopting alternating-current motor/AC motor, select I retaining, II retaining, III retaining for use, to adapt to the characteristic of the high rotating speed of alternating-current motor/AC motor, low torque, when adopting DC motor, select II retaining, III retaining, IV retaining for use, to adapt to the characteristic of DC motor slow speed of revolution, high torque (HT).The structural principle of total system as shown in Figure 1.The size of motor output shaft 2 and input shaft 7 as shown in Figure 2, spline specification: EXT30Z * 1.5M * 30R * 6h.
Electronic control unit 11 is cores of automatic guidance part, is made up of power circuit, input block, micro controller system, electric motor oil door control unit, speed change actuating unit driver element, has the function of storage, computing, receiving and transmitting signal.Adopt the MC68HC9S12DP256 micro controller system of Motorola, input block is divided into pwm signal input block, analog signal input block, on-off signal input block, digital signal input block.Pwm signal is an impulse singla, comprises the tach signal of vehicle speed signal, motor speed signal and transmission output shaft 9; Analog signal comprises acceleration pedal aperture signal, brake pedal aperture signal, battery tension current signal; On-off signal comprises gear on-off signal, BK Brake Switch signal; Digital signal comprises the state-of-charge value of storage battery.The speed change actuating unit is used for the corresponding mechanical action of electric signal instruction becoming with electronic control unit, thereby realizes self shifter, and electrical motor throttle actuating unit power demand is less, adopts step motor drive, and speed-changer executing mechanism adopts hydraulic efficiency pressure system to realize.The structural principle of electronic control unit as shown in Figure 3.
The automatic control of transmission principle: chaufeur is controlled the aperture of acceleration pedal or brake pedal according to current driving state, running environment and the dbjective state of elec. vehicle, the signal input electronic control unit 11 that pedal aperture signal and other collect, electronic control unit 11 is reference with current this tittle, according to logic that configures and algorithm, draw next step control policy, handle corresponding actuating unit by electric control signal again, electrical motor and change-speed box are controlled, thereby the automation that realizes starting, gearshift, regenerative brake is controlled.Electrical motor 11 is operated under the generating state during regenerative brake, and this mechanical energy of braking energy is converted into electric energy, charges a battery, thereby braking energy is stored in the storage battery.The variable speed control principle as shown in Figure 4.
From above structure and control principle as can be seen, motor-driven and transmission structures compactness, easy to assembly, on the basis of existing machinery change-speed box, automation has been controlled in the manipulation of choosing, gearshift, can also mate two kinds of dissimilar electrical motors of AC and DC, have that the production inheritance is good, improvement expenses is low, assembling is simple, the advantage of flexible configuration.
