detailed description of the invention
Be illustrated in figure 1 according to an embodiment of a kind of double-clutch automatic gearbox protection of the utility model and energy recycle device.This device is by controller 1, brake pedal displacement pickup 2, car speed sensor 3, dynamometer actuator 4, energy consumption device 5, power splitting mechanism 6, drg 7, speed increaser 8, the double-clutch automatic gearbox fender guard that electric dynamometer 9 forms, speed increaser 8 one end and electric dynamometer 9 mechanical connections, speed increaser 8 other ends and double-clutch automatic gearbox mechanical connection, when being increased, power speed in the time that power splitting mechanism 6 passes to speed increaser 8 of driving engine exports to electric dynamometer 9, at this moment therefore generating efficiency is higher due to rotating speed height for electric dynamometer 9, being conducive to energy reclaims, increase braking force need to power splitting mechanism 6 because speed is high time simultaneously, because the speedup of speed increaser subtracts torsion effect, therefore more easily realize, in the time that the speed of a motor vehicle is higher, chaufeur is stepped on brake pedal, but controller 1 does not send control command, drg 7 is in braking mode, now, gear ring is connected with the output shaft of automotive engine, pinion carrier and double-clutch automatic gearbox mechanical connection, the power of automotive engine passes to gear ring by the output shaft of driving engine, transmission of power is to satellite gear, brake because sun wheel is braked device 7, therefore transmission of power, to pinion carrier, passes to double-clutch automatic gearbox, finally pass to wheel, now driving engine and wheel speed decline simultaneously.When the speed of a motor vehicle low when the certain numerical value, controller 1 is controlled drg 7, drg 7 unclamps, and the power of automotive engine passes to gear ring by the output shaft of driving engine, passes to satellite gear, because not being braked device 7, sun wheel brakes, therefore a power part passes to sun wheel, transmits speed increaser 8, passes to electric dynamometer 9, electric dynamometer 9 generatings are stored in battery, or are consumed by energy consumption device 5; Another part transmission of power, to pinion carrier, passes to double-clutch automatic gearbox through pinion carrier, finally passes to wheel, realize Reduced Speed Now, and engine speed does not decline, and therefore driving engine can not stop working.The allocation proportion of transmission of power is determined by the heap(ed) capacity of electric dynamometer 9.And the heap(ed) capacity of electric dynamometer 9 to be control commands of being sent by controller 1 determine.Controller 1 can, by detecting the information of brake pedal displacement pickup 2, determine heap(ed) capacity.
Energy consumption device 5 is made up of switch 5.1, resistance 1, resistance 2 5.3, zener diode 5.4, resistance 3 5.5, transistor 1, resistance 4 5.7, transistor 2 5.8, heating wire 5.9, blower fan 5.10, when energy consumption device 5 is worked, controller 1 is added on resistance 1 and resistance 2 5.3 the closed power line voltage of switch 5.1.In the time that system voltage is not high, zener diode 5.4 does not have breakdown in reverse blocking state, transistor one 5.6 not conductings, and the base tension of transistor 2 5.8 is zero, transistor 2 5.8 not conductings, heating wire 5.9 heatings and blower fan 5.10 are not worked.In the time that system capacity is too much, power line voltage is higher, the voltage of resistance 1 and resistance 2 5.3 point of connection also can increase, exceed after the punching voltage of zener diode 5.4, the breakdown base stage conducting through transistor 1 of zener diode 5.4, therefore conducting of transistor 1, electric current forms pressure drop through resistance 4 5.7, produce voltage in resistance 4 5.7 upper ends, resistance 4 5.7 upper ends are connected with the base stage of transistor 2 5.8, therefore transistor 2 5.8 conductings, now large electric current has positive source through heating wire 5.9, blower fan 5.10, be communicated with ground through transistor 2 5.8, heating wire 5.9 heatings and blower fan 5.10 dispel the heat excess energy are consumed.Resistance 3 5.5 wherein plays dividing potential drop effect.
