Accompanying drawing explanation
Fig. 1 is the principle of work and power schematic diagram of the present invention.
Detailed description of the invention
Shown in Fig. 1, relating to the drive system of a kind of three gear electric automobiles, including electrokinetic cell 2, its input is connected with charging inlet 1；First outfan of described electrokinetic cell 2 is connected with control unit 6, provides high-pressure work power supply for control unit 6, electricity, temperature and current information is fed back to control unit 6 simultaneously；Second outfan of described electrokinetic cell 2 is connected with booster battery 4 by DC/DC transducer 3；The outfan of described booster battery 4 is connected with control unit 6 by ignition switch 5, provides low-voltage supply for described control unit 6；The input of described control unit 6 is connected with accelerator pedal position sensor, shift sensor, braking sensor and vehicle speed sensor respectively, the control output end of described control unit 6 is connected with motor 7, and the outfan of described motor 7 passes sequentially through simple planetary arrangement 12, main reducing gear 16 and differential mechanism 17 and is connected with wheel 18.
In concrete scheme, the first output shaft of described motor 7 is connected with the sun gear 14 in described simple planetary arrangement 12, and the second output shaft is connected with the gear ring 13 in described simple planetary arrangement 12；The first output shaft that first signal output part of described control unit 6 controls described motor by first clutch 9 engages with the sun gear 14 in described simple planetary arrangement 12, the second output shaft that its secondary signal outfan controls described motor by second clutch 8 engages with the gear ring 13 in described simple planetary arrangement 12, sun gear 14 in described simple planetary arrangement 12 is braked by its 3rd signal output part by the first brake 11, gear ring 13 in described simple planetary arrangement 12 is braked by its 4th signal output part by second brake 10.
Wherein, when described motor 7 is brushless, permanently excited direct current motor, its running voltage is electrokinetic cell voltage, and it is controlled by control unit 6.When motor 7 is drive pattern, control unit 6 controls rotation direction and the rotating speed size of motor 7 by controlling phase sequence and frequency；Control unit 6 also can control motor 7 and be in power generation operation pattern, and the part kinetic energy that vehicle travels is converted into electric energy, is namely carried out " energy regenerating ".Meanwhile, the technical parameter such as rotor-position, motor temperature is fed back to control unit 6 by motor 7, in order to motor 7 is controlled by control unit 6, when necessary also can starting protection pattern.
In the present invention, control unit 6 is mainly used in receiving and processing various external input signal, controls the rotating speed of motor 7 and rotation direction according to preset program, also can control when energy recuperation mode motor the kinetic energy of vehicle is carried out energy regenerating, to power battery charging；Control the action of each Clutch and brake according to preset program, make each Clutch and brake be in different duties；Meanwhile, the technical parameter information such as voltage, electric current, temperature, electricity are fed back to control unit by electrokinetic cell, and control unit is adjusted controlling parameter or revises, when necessary also can starting protection pattern.
Operation principle and work process: ignition switch 5 closes, electric automobile enters duty.The control unit 6 signal according to sensors such as accelerator pedal position, gear, braking, speeds, by analyzing, calculate the duty of the pattern determined motor and whether work and work, each Clutch and brake.Wherein, the duty of each executive component, mode of operation and switching all automatically control, and it also determines the duty of electric automobile.
Empty (N) gear: when gear on-off is in neutral, motor does not work, and all clutches are all not braking all in released state, all brakes.
Advance (D) gear: when being in forward gear stepping on accelerator pedal when gear on-off, and control unit controls each executive component and walks with 1 dammed up, then further according to the signal of the sensor such as accelerator pedal position, speed, and automatic control operation mode and add downshift.During each forward gear, the duty of executive component is as follows.
(1) 1 gear: motor rotates forward, and first clutch 9 engages, second clutch 8 does not engage, the first brake 11 is not braking, second brake 10 is braked.
