The 3rd embodiment
A kind of hybrid vehicle comprises a motor 4, first motor 51 and one second motor 52, also comprises an above-mentioned automobile chassis, and it links to each other with described motor 4, described first motor 51 and described second motor 52, as shown in Figure 1.
Wherein, the output shaft 41 of described motor 4 links to each other with these second gear ring, 21 centers of rotation, the output shaft 511 of this first motor 51 passes this second motor 52 and these 12 coaxial connections of first sun gear, the stator 522 of this second motor 52 maintains static, rotor 521 links to each other with this first gear ring 11, and with these first gear ring, 11 coaxial rotation.
The output shaft of this second motor 52 is sleeves, and the left end of sleeve is connected with this first gear ring 11 in the mode of spline, and the output shaft of this first motor 51 passes through from the centre of this sleeve, and by bearings on sleeve lining.
In addition, this hybrid vehicle also comprises first a gear ring fixing device 61 that links to each other with this first gear ring 11, second a gear ring fixing device 62 that links to each other with this second gear ring 12.
During vehicle starting, first motor 51 produces torque T with electric motor mode work
1, second motor 52 is not worked, the first gear ring fixing device, 61 work simultaneously, and first gear ring 11 is fixing, and the second gear ring fixing device 62 is also worked, and second gear ring 21 is fixing, and motor 4 is not worked.The torque that produce this moment on first planet carrier 14 is (k
1+ 1) T
1Because motor 4 is not worked, so the output torque of second planet carrier 24 is (k
1+ 1) (k
2+ 1) T
1Therefore the final driving torque that produces on wheel 9 is T=k
3(k
1+ 1) (k
2+ 1) T
1Because k
1, k
2And k
3All greater than 1, just can be with less motor start-up torque T
1Produce bigger driving torque T.
When automobile moved at the low speed light duty, motor 4 was not still worked, and 62 work of the second gear ring fixing device are fixing with second gear ring 21.First motor 51 and second motor 52 are established its rotating speed and are respectively n all with electric motor mode work
1And n
2, the first gear ring fixing device 61 quits work simultaneously, and the rotor 521 that makes first gear ring 11 and second motor 52 is with identical rotational speed.The rotating speed that this moment, first planet carrier 14 was exported is so
The rotating speed that further can obtain second planet carrier 24 is
Therefore the rotating speed of wheel 9 is
Automobile is when running at high speed the operating mode operation, and the second gear ring fixing device 62 quits work, and motor 4 begins ignition operation under the drive of second gear ring 21, produce rotation speed n
3First motor 51 and second motor 52 are all with electric motor mode work, and the rotating speed of establishing them is respectively n
1And n
2, the first gear ring fixing device 61 quits work simultaneously, and the rotor 521 that makes first gear ring 11 and second motor 52 is with identical rotational speed.The rotating speed of wheel 9 is so at this moment
This shows, if n
2And n
1Constant, n no matter
3Get what value, n
bAll greater than n
aThereby, realize running at high speed.
When automobile moves in the cruising operating mode, the second gear ring fixing device 62 quits work, motor 4 begins ignition operation under the drive of second gear ring 21, and be operated in the optimum state rapidly, first motor 51 is with electric motor mode work, 52 states that are operated in generator of second motor, the additional energy that the motor 4 and first motor 51 produce will be converted to electrical power storage in storage battery by second motor 52.
When automobile brake, in two kinds of situation, if storage battery is full of, motor 4 is in the state of quitting work so, and the second gear ring fixing device 62 is in running order simultaneously, and first motor 51 and second motor 52 also quit work.If storage battery is not full of, motor 4 is in running order so, the second gear ring fixing device 62 is not worked simultaneously, first motor 51 and second motor 52 are with generator mode work, the energy that produce when reclaiming braking on the one hand this moment, transformation of energy with motor becomes electrical power storage in storage battery on the other hand, if automobile stops, motor 4 works on so, first motor 51 and second motor 52 are still with generator mode work, the energy that motor 4 is produced changes into electrical power storage in storage battery, after storage battery is full of, and motor 4, first motor 51 and second motor 52 just quit work.
