Below needing to be divided in conjunction with the accompanying drawings eight steps elaborates to the power transmission line of 6 forward gearss of engine-driving pattern.
The power transmission line of 1 grade of the 2 pairs of engine-driving pattern elaborates in conjunction with the accompanying drawings:
The first step is the launch process of automobile: when the driver rotates key when piloting engine, the flywheel of motor clockwise rotates with regard to idling and transmission of power is arrived buffering coupling 1, buffering coupling 1 arrives overrunning clutch 2 with transmission of power, overrunning clutch 2 arrives input shaft 3 with transmission of power, input shaft 3 has two power transmission lines: article one power transmission line is that input shaft 3 arrives motor field frame 28 with transmission of power, motor field frame 28 arrives oil pump input shaft 26 with transmission of power, oil pump input shaft 26 with transmission of power to oil pump 25, the second power transmission line be input shaft 3 with transmission of power to first sun gear 7, K1 clutch 22, K2 clutch 21 and all clockwise rotating.
Second step was the neutral process of automobile: when the driver toggles it to advancing during gear of engine-driving pattern with gear, the hydraulic system of automatic transmission computer control meanwhile, just push away K1 clutch 22 and connected intermediate propeller shaft 9 by oil pressure, intermediate propeller shaft 9 just clockwise rotate and with transmission of power to second sun gear 11 and the 3rd sun gear 14, the 3rd sun gear 14 just clockwise rotates and transmission of power is arrived the third line star-wheel 13, the third line star-wheel 13 just rotates counterclockwise and with transmission of power to the three ring gears 17, the 3rd ring gear 17 rotate counterclockwise and with transmission of power to second planet carrier 12, second planet carrier 12 drive second planet wheel around second sun gear 11 rotate counterclockwise and with transmission of power to second ring gear 19, second ring gear 19 rotate counterclockwise and with transmission of power to first planet carrier 8, first planet carrier 8 just rotate counterclockwise and with transmission of power to first planet wheel 6, first planet wheel 6 just around first sun gear 7 rotate counterclockwise and with transmission of power to first ring gear 23, first ring gear 23 just rotates counterclockwise and transmission of power is arrived rotor of output shaft axle 5, rotor of output shaft axle 5 just rotates counterclockwise, therefore automobile is in neutral gear.
The 3rd step was the starting-up process of automobile: when the driver loosens the hand brake and accelerator pedal, and the hydraulic system of automatic transmission computer control, promote the reverse that B3 break 18 has slowly been braked the 3rd ring gear 17 and second planet carrier 12 by hydraulic oil, because the 3rd sun gear 14 has clockwise rotated and transmission of power is arrived the third line star-wheel 13, the third line star-wheel 13 will rotate counterclockwise in the 3rd ring gear 17 and transmission of power is arrived the third line star frame 15, the third line star frame 15 just clockwise rotates and transmission of power is arrived output shaft 16, output shaft 16 just clockwise rotates and outputting power.So 1 grade power transmission line is set up.
Below be the process that automobile generates electricity under steam simultaneously: when 1 grade power transmission line is set up, second sun gear 11 clockwise rotated and with transmission of power to second planet wheel 10, second planet wheel 10 just rotate counterclockwise and with transmission of power to second ring gear 19, second ring gear 19 just rotate counterclockwise and with transmission of power to first planet carrier 8, first planet carrier 8 just rotate counterclockwise and with transmission of power to first planet wheel 6, meanwhile first sun gear 7 clockwise rotated and with transmission of power to first planet wheel 6, first planet wheel 6 just rotate counterclockwise and with transmission of power to first ring gear 23, first ring gear 23 just rotates counterclockwise and transmission of power is arrived rotor of output shaft axle 5, because rotor of output shaft axle 5 rotates counterclockwise, because motor stator 27 is along with input shaft 3 clockwise rotates, therefore as long as just can make motor stator 27 generatings to rotor of output shaft axle 5 input electromagnetic fields, when motor stator 27 clockwise rotates generating, and produced the active force that clockwise rotates for rotor of output shaft axle 5 by electromagnetic field, reaction force when this active force is rotor of output shaft axle 5 generatings.
The speed of a motor vehicle behind vehicle starting rises gradually, automatic transmission computer expert crosses the speed of a motor vehicle that sensor can be judged automobile running, can judge the resistance of automobile running, reaction force in the time of can judging rotor of output shaft axle 5 generatings, the reaction force of judging rotor of output shaft axle 5 generatings when the automatic transmission computer is during greater than the resistance of automobile running, the hydraulic system of automatic transmission computer control, just discharge the oil pressure of B3 break 18, B3 break 18 is with regard to loosen the brake the 3rd ring gear 17 and second planet carrier 12, the resistance that replaces 18 brakings of B3 break by the reaction force of rotor of output shaft axle 5, learn that according to above-mentioned transmission process analysis two kinds of resistances exist: first kind of resistance is the reaction force that produces during from rotor of output shaft axle 5 generatings, second kind of resistance is to be resistances of automobile running from output shaft 16, since second sun gear 11 clockwise rotated and with transmission of power to second planet wheel 10, second planet wheel 10 just rotates counterclockwise and can the described two kinds of resistance of balance to second ring gear 21 and second planet carrier, 12, the second planet wheels 10 with transmission of power, thereby vehicle is generated electricity under steam simultaneously can not waste the power of motor.
Power transmission line below in conjunction with 2 grades of 3 pairs of engine-driving patterns of accompanying drawing elaborates: the 4th step, when the driver quickens accelerator pedal, the speed of a motor vehicle rises gradually simultaneously, when the automatic transmission computer judges that the speed of a motor vehicle reaches 2 grades speed, the resistance of judging rotor of output shaft axle 5 generatings when the automatic transmission computer is during less than the resistance of automobile running, the hydraulic system of automatic transmission computer control, just control oil pressure promotion B2 break 20 and slowly braked second ring gear 19 and first planet carrier 8, thereby the brake drag that makes B2 break 20 replaces the resistance of rotor of output shaft axle 5 generatings, since second sun gear 11 clockwise rotated and with transmission of power to second planet wheel 10, second planet wheel 10 just rotates counterclockwise in second ring gear 19, and with transmission of power to second planet carrier 12, second planet carrier 12 just clockwise rotates and with transmission of power to the three ring gears 17, the 3rd ring gear 17 just clockwise rotates and transmission of power is arrived the third line star-wheel 13, learn according to above-mentioned transmission process analysis, the 3rd sun gear 14 has clockwise rotated in the time of 1 grade, the 3rd ring gear 17 begins to clockwise rotate when rising up into 2 grades, and 2 grades the rotating speed of therefore advancing is the rotating speed that the rotating speed of the 3rd sun gear 14 adds the 3rd ring gear 17, the common the third line star-wheel 13 that drives, the third line star-wheel 13 just can two kinds of driving forces of balance and with transmission of power to the third line star frame 15, the third line star frame 15 just clockwise rotates and transmission of power is arrived output shaft 16, output shaft 16 just clockwise rotates and outputting power.So 2 grades power transmission line is set up.
