Detailed description of the invention
Show speed changer 1 according to the first embodiment of Fig. 1 to 3, this speed changer has for drivingThree gears of the axletree 2 of motor vehicle, these motor vehicles especially refer to car. Motor vehiclesThe active wheel that is subordinated to this axletree 2 represent with Reference numeral 3, the differential mechanism of axletree 2 is with attachedFigure mark 4 represents.
Speed changer 1 has two transmission shafts that are arranged in parallel 5 and 6. Transmission shaft 5 isThe power shaft being connected with motor 7 of speed changer 1. Axletree 2 arrange with these two speed changersAxle 5 is parallel with 6.
Near motor 7, the pinion 8 that is configured to spur gear anti-rotationly with transmission shaft 5Be connected, this pinion engages with gear wheel 9. This gear 9 is by having mechanical stop part 10Freewheel clone is at transmission shaft 6 places. In addition, be configured to the pinion 11 of spur gear anti-rotationGround is connected with transmission shaft 6. This pinion is as final drive (Final-Drive) and largeGear 12 engages, this gear wheel and differential mechanism 4 actings in conjunction.
In the region of the end of the motor dorsad 7 of transmission shaft 5, this transmission shaft is equipped withClutch 13. The pinion 14 that is configured to spur gear is set to transmission shaft 5 coaxial. FromClose in the situation of device 13 closures, these gear 14 carry-over moment ground are connected with transmission shaft 5.
This gear 14 and 15 actings in conjunction of speed changer part, this speed changer part hasThe gear wheel 16 larger than gear 11, wherein this gear 16 is by having mechanical stop part 17Freewheel and the coaxial setting of transmission shaft 6 and anti-rotation be connected with gear 11.
Planetary transmission 18 is also set to transmission shaft 6 coaxial, wherein carries planet toothThe piece 20 that connects of the planetary gear 19 of wheel speed 18 is set to and and tooth coaxial with transmission shaft 6Wheel 16 is connected. The rim gear wheel 21 of planetary transmission 18 anti-rotationly with transmission shaft 6 phasesConnect. The sun gear 22 of planetary transmission 18 by brake 23 with regard to its rotation and Yan ShikeFix.
The speed changer 1 that the embodiment of Fig. 1 to 3 describes has the following work by Fig. 1 to 3 descriptionBy mode:
The first gear shown in Fig. 1 has than the less gearratio of the second gear shown in Fig. 2, theTwo gears have the gearratio less than the third gear shown in Fig. 3.
In the first gear, open clutch 13 and brake 23. Moment stream or torque are from electronicMachine 7 advances towards transmission shaft 5, and from this by gear 8, gear 9, there is machinery resistanceThe freewheel (wherein it is arranged in its blocking position) of block piece 10 advances towards transmission shaft 6, andAnd advance towards gear 12 by gear 11 from this transmission shaft, further by differential mechanism 4Advance towards active wheel 3 with axletree 2.
Moment stream is shown in broken lines in Fig. 1.
In all figure that other is not also discussed, moment stream is shown in broken lines equally, and this foreign ministerSame Reference numeral carrys out the corresponding parts of mark.
In the second gear (as shown in Figure 2), clutch 13 is closed. Moment stream is as followsGround advances: motor 7, transmission shaft 5, clutch 13, gear 14, gear 16, haveThe freewheel (being arranged in the position that it stops) of mechanical stop part 17, gear 11, gear 12,Differential mechanism 4, axletree 2, active wheel 3. Therefore there is the freewheel access of mechanical stop part 17In the second gear time, there is the freewheel faster (ü berholt) of mechanical stop part 10, becauseThe second gear rotates sooner than the first gear.
In third gear (as shown in Figure 3), clutch 13 and brake 23 are closed.Moment stream advances as follows: motor 7, transmission shaft 5, clutch 13, gear 14, toothTake turns 16, connect piece 20, planetary gear 19, rim gear wheel 21, transmission shaft 6, gear 11, gear12, differential mechanism 4, axletree 2, active wheel 3. Therefore the in the situation that of brake 23 closure,In planetary transmission 18, produce transmission. Torque is delivered to last by rim gear wheel 21On driver (final drive). If sun gear 22 is fixing, at planetary transmissionIn 18, produce transmission, driven movable contact block 20, and rim gear wheel 21 has been used as to driven shaft.
In third gear (as shown in Figure 3), have mechanical stop part 10 freewheel andThe freewheel with mechanical stop part 17 is all faster, because third gear is than the first gear and secondGear rotates sooner.
Therefore, speed changer preferably has four gearratios. The first gearratio is at gear 8 and gear 9Between realize, the second gearratio is realized between gear 14 and gear 16, the 3rd gearratio existsIn planetary transmission 18, realize, and the 4th (last) gearratio is in final transmissionIn the region of device, realize, in the region of gear 11 and 12, realize.
Gear shift between each gear can realize the in the situation that of interruptible load not. This is also applicable to downThe scheme that face also can elaborate.
Fig. 4 has shown another transmission variant, and wherein rim gear wheel 21 is provided with brake 24. With rootEmbodiment according to Fig. 1 to 3 is different, revolving according to sun gear in the embodiment of Fig. 4 22 is anti-Turn and be connected with transmission shaft 6. Therefore, moment flows in third gear in clutch 13 closuresWith in the situation of brake 24 closures, advance as follows: motor 7, transmission shaft 5, clutchDevice 13, gear 14, gear 16, connect piece 20, planetary gear 19, sun gear 22, transmission shaft6, gear 11, gear 12, differential mechanism 4, axletree 2, active wheel 3.
In third gear, there is the freewheel of mechanical stop part 10 and there is mechanical stop part17 freewheel is all faster, because third gear is rotated sooner. About of the first embodimentOne and the explanation of the second gear be also applicable to this first and second gear.
Fig. 5 shows another connection possibility, and the region of itself and the first embodiment is, has cancelledThere is the freewheel of mechanical stop part 17, and for this reason in the scope of planetary transmission 18Inside be provided with extra clutch 25. This clutch is arranged on and connects between piece 20 and rim gear wheel 21.In this variant, in third gear, produce the moment stream advancing as follows: motor 7, speed changeDevice axle 5, clutch 13, gear 14, gear 16, connect piece 20, clutch 25, planetary gear19, rim gear wheel 21, transmission shaft 6, gear 11, gear 12, differential mechanism 4, axletree 2,Active wheel 3. Therefore, clutch 13 and 25 is closed in third gear, and brake 23 is alsoClosed. The freewheel with mechanical stop part 10 is faster, because third gear is rotated sooner.
According to the embodiment of Fig. 6 be according to the difference of the embodiment of Fig. 1 to 3, arrangeThere is explosive motor 26 to replace motor 7, can drive speed transmission axle by this explosive motor5, and be provided with motor 27 and replace brake 23, this motor anti-rotationlyly and the sunWheel 22 is connected. Therefore in the time of the stationary rotor of motor 27, produced the reality with Fig. 1 to 3Execute the situation that example is identical. In the time that motor 27 turns round, in the third gear of speed changer 1, realizeFurther transmission, or can in best load point, operate explosive motor 26. ?In three gears, there is the freewheel of mechanical stop part 10 and have mechanical stop part 17 fromAll faster by taking turns, because third gear is rotated sooner.
