For reaching above-mentioned utility model object the technical solution adopted in the utility model be: 1. a double-clutch automatic gearbox fender guard, by controller 1, add carrier aircraft actuator 2, car speed sensor 3, brake pedal displacement pickup 4, power splitting mechanism 5, drg 6, add the double-clutch automatic gearbox fender guard that carrier aircraft 7 forms, controller 1 with add carrier aircraft actuator 2, car speed sensor 3, brake pedal displacement pickup 4, drg 6 is electrically connected, power splitting mechanism 5 is through drg 6 and add carrier aircraft 7 mechanical connections, add carrier aircraft 7 and add carrier aircraft actuator 2 and be electrically connected, adding carrier aircraft 7 can be eddy current absorption dynamometer, can be electric dynamometer, can also be electromagnetic power brake, drg 6 is normally engaged brake.
2. the further technical scheme that the utility model adopts is: power splitting mechanism 5 is made up of gear ring input shaft 5.1, gear ring 5.2, satellite gear 5.3, pinion carrier 5.4, planet carrier output shaft 5.5, sun wheel 5.6, sun gear output shaft 5.7, described gear ring 5.2, satellite gear 5.3, pinion carrier 5.4, sun wheel 5.6 form simple planetary arrangement, gear ring input shaft 5.1 is wherein connected with the output shaft of automotive engine, planet carrier output shaft 5.5 and double-clutch automatic gearbox mechanical connection, and sun gear output shaft 5.7 is through drg 6 and add carrier aircraft 7 mechanical connections.
Adopt a kind of double-clutch automatic gearbox fender guard of the utility model to there is following beneficial effect:
1. the power splitting mechanism 5 of a kind of double-clutch automatic gearbox fender guard of the utility model is given the power distribution of driving engine to add carrier aircraft 7; and by adding carrier aircraft, energy is consumed; the frictional heating burden that alleviates power-transfer clutch, reduces wear, and extends the service life of power-transfer clutch.
A kind of double-clutch automatic gearbox fender guard of the utility model power splitting mechanism 5 adopt simple planetary arrangement, compact conformation, occupies little space and is conducive to transmissions improved and promoting the use of.
3. the carrier aircraft 7 that adds of a kind of double-clutch automatic gearbox fender guard of the utility model can be eddy current absorption dynamometer; can be electric dynamometer, or electromagnetic power brake, they are all electronically controlled; therefore easy controlled loading amount, when chaufeur is slowed down, running car is stable does not shake.
Below in conjunction with drawings and Examples, a kind of double-clutch automatic gearbox fender guard of the utility model is described further.
Accompanying drawing explanation
Fig. 1: the structure principle chart of a kind of double-clutch automatic gearbox fender guard of the utility model.
Fig. 2: the power splitting mechanism schematic diagram of a kind of double-clutch automatic gearbox fender guard of the utility model.
The specific embodiment
Be illustrated in figure 1 an embodiment according to a kind of double-clutch automatic gearbox fender guard of the utility model.Controller 1 is electrically connected with car speed sensor 3, brake pedal displacement pickup 4, gather speed of a motor vehicle brake pedal displacement information, controller 1 with add carrier aircraft actuator 2 and be connected, can give the controlling quantity that adds carrier aircraft 7 by controlled loading machine actuator, controller 1 is electrically connected with drg 6, in the time of needs low speed driving, drg 6 is unclamped, power splitting mechanism 5 through drgs 6 with add carrier aircraft 7 mechanical connections, add carrier aircraft 7 and add carrier aircraft actuator 2 and be electrically connected; Adding carrier aircraft 7 can be eddy current absorption dynamometer, can be electric dynamometer, can also be electromagnetic power brake; Drg 6 is normally engaged brake.
The gear ring 5.2 of power splitting mechanism 5, satellite gear 5.3, pinion carrier 5.4, sun wheel 5.6 forms simple planetary arrangement, gear ring input shaft 5.1 is wherein connected with the output shaft of automotive engine, planet carrier output shaft 5.5 and double-clutch automatic gearbox mechanical connection, sun gear output shaft 5.7 and drg 6 mechanical connections, in the time that the speed of a motor vehicle is not low, controller is not to controlling, drg 6 is in braking mode, the power of automotive engine passes to gear ring input shaft 5.1 by the output shaft of driving engine, pass to gear ring, pass to satellite gear, because being braked device 6, sun wheel brakes, therefore transmission of power is to pinion carrier, pass to double-clutch automatic gearbox through planet carrier output shaft 5.5, finally pass to wheel.In the time that the speed of a motor vehicle is low, controller is controlled drg 6, drg 6 is in releasing orientation, the power of automotive engine passes to gear ring input shaft 5.1 by the output shaft of driving engine, passes to gear ring, passes to satellite gear, because not being braked device 6, sun wheel brakes, therefore a power part passes to sun wheel, passes to and adds carrier aircraft 7 through sun gear output shaft 5.7, and energy is loaded machine and consumes.Another part transmission of power, to pinion carrier, passes to double-clutch automatic gearbox through planet carrier output shaft 5.5, finally passes to wheel.The allocation proportion of transmission of power is determined by the heap(ed) capacity that adds carrier aircraft 7.And being the control command of being sent by controller, the heap(ed) capacity that adds carrier aircraft 7 determines.Controller 1 can, by detecting the information of brake pedal displacement pickup 4, determine heap(ed) capacity.
