Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this.
As shown in Figure 1, hybrid electric vehicle power transmission system described in the utility model, comprises motor, motor, the first axle 9 be arrangeding in parallel, the second axle 11, described the first axle 9 is connected with motor by clutch 10, and described the second axle 11 is connected with motor by electric clutch 18, the first axle constant mesh gear 1 setting gradually on away from motor direction on the first axle 9, the first six grades, axle driven gear 2, five or six grades of synchronizers 3, the first five grades, axle driven gear 4, the first axle fourth gear driven gear 5, the first axle three fourth gear synchronizers 6, the first axle third gear driven gear 7, motor driven gear 8, the motor driving gear 17 setting gradually on away from motor direction on the second axle 11, the second axle third speed drive gear 16, the second axle fourth gear driving gear 15, the second five grades, axle driving gear 14, the second six grades, axle driving gear 13, the second axle constant mesh gear 12, described the first axle constant mesh gear 1, the first six grades, axle driven gear 2, five or six grades of synchronizers 3, the first five grades, axle driven gear 4, the first axle fourth gear driven gear 5, the first axle three fourth gear synchronizers 6, the first axle third gear driven gear 7, motor driven gear 8 respectively with motor driving gear 17, the second axle third speed drive gear 16, the second axle fourth gear driving gear 15, the second five grades, axle driving gear 14, the second six grades, axle driving gear 13, the second axle constant mesh gear 12 engagements.
The utility model, has completely abolished original one grade of gear, and intermediate gear, the power plant by motor during as vehicle start.In concrete structure, the output terminal of motor is equipped with the electric clutch 18 of being controlled by ECU, automatically controls the break-make of motor power.The power of motor output is by motor driving gear 17, and motor driven gear 8, finally by the first axle 9 output torques.
The in the situation that of starting and low speed, employing electric-only mode travels, ECU controls electric clutch 18 in bonding state, by motor, provide driving force, power is spread out of by motor rotor, through motor driving gear 17, motor driven gear 8 is delivered to output shaft, and final driven wheel rotates.
When reversing, only motor need to be reversed, transfer route when its power transmission line is started to walk with low speed is identical, so the use of having saved reverse gear, has reduced the size of cost and whole speed changer.
When running at high speed, adopt pure engine mode, now ECU solenoidoperated cluthes, in off state, only provide power by motor, take five grades as example, the power of motor, through clutch 10, the first axle constant mesh gears 1, the second axle constant mesh gear 12, through five grades of driving gears 14 of the second axle, be delivered to five grades of driven gears 4 of the first axle, being delivered on the first axle 9 through five or six grades of synchronizers 3, by the first axle 9, torque exported.
In anxious acceleration, or the peak torque of motor is can not meet current working and require time, by motor and motor, provides power simultaneously.Take third gear as example, specifically describe as follows: engine start, clutch 10 combinations, power is by motor process clutch 10, the first axle constant mesh gear 1, the second axle constant mesh gear 12, the second axle third speed drive gears 16, the first axle third gear driven gear 7, then through three fourth gear synchronizers 6, transmission of power is exported to the first axle 9.ECU controls electric clutch 18 in bonding state simultaneously, and motor continues to provide power according to electric-only mode, and two kinds of power are coupled on the first axle 9, output.
Under brake condition, clutch 10 is in off state, motor is not worked, ECU controls electric clutch 18 in bonding state, now motor is in generating state, kinetic energy is delivered to motor driven gear 8 by the first axle 9, and motor driving gear 17 is generated electricity by motor driving gear 17 drive motors.
Described embodiment is preferred embodiment of the present invention; but the present invention is not limited to above-mentioned mode of execution; in the situation that not deviating from flesh and blood of the present invention, any apparent improvement, replacement or modification that those skilled in the art can make all belong to protection scope of the present invention.
