Embodiment
Embodiment 1
As shown in figure 1, it is provided with an input shaft in a kind of mechanical stepless transmission, including gearbox case H, gearbox case H Lin, a first axle L1, a second axle L2, a 3rd axle L3With an output shaft Lout；Input shaft LinIt is provided with input tooth Take turns Zin, first axle L1One end be provided with differential mechanism A, differential mechanism A one end and first axle L1It is connected, the other end and the second axle L2Phase Even, differential mechanism A is provided with gear ZA, gear ZAWith input gear ZinEngagement, the 3rd axle L3One end be connected with a planetary mechanism B, planetary mechanism B one end and the 3rd axle L3Connection, the other end and output shaft LoutConnection, first axle L1It is provided with first gear Z1, the second axle is provided with second gear Z2, the 3rd axle L3It is provided with the 3rd gear Z3, planetary mechanism B shell is provided with gear ring B1, First gear Z1With second gear Z2It is located at differential mechanism A both sides, first gear Z respectively1With the 3rd gear Z3Engagement, the second tooth Wheel and gear ring B1Engagement, the second axle L2One-way clutch C is provided with, one-way clutch C is located at second gear Z2Away from differential mechanism A One end.
The planetary mechanism B includes gear ring B1, central gear B2With planet carrier B4, planet carrier B4It is provided with two planet teeth Take turns B3, planetary gear B3With gear ring B1Connection, central gear B2With planetary gear B3Intermeshing, central gear B2Installed in the 3rd Axle L3On, planet carrier B4Installed in output shaft LoutOn.
The first gear Z1, second gear Z2, the 3rd gear Z3, input gear Zin, gear ring B1, gear ZAGearratio It is equal.
The power being subject to is divided into two power to connected first axle L by the differential mechanism A1And the second axle L2。
The power transmission path of the present embodiment is as follows：
1st, through input gear ZinIt is input in differential mechanism shell A；
2nd, differential mechanism A the first output bevel gear wheel A is passed through3, the second output bevel gear wheel A4Divide two-way output；
3rd, the first output bevel gear wheel A3The power of output passes through first gear Z1With the 3rd gear Z3Pass to the planetary mechanism B sun Gear B3, while the second output bevel gear wheel A4The power of output passes through second gear Z2Pass to planetary mechanism B gear ring B1；
4th, planetary mechanism B planetary gear is simultaneously by central gear B3With gear ring B1Do and drive planet carrier B with producing to rotate4Turn It is dynamic, output power；
5th, in the case where input is constant, with planet carrier B4The external resistance increase being subject to, B4Rotating speed will reduce, gear ring B1Turn Speed will also decrease until stopping producing reversion again.One-way clutch C, which can now be added, ensures gear ring B1Reversion is not produced, so as to Form a gear ring B1It is fixed, central gear B3Input, planet carrier B4The reducing gear of output.
The use principle of the present embodiment is：
1st, as output shaft LoutOn the resistance torque that is subject to when being 0, input shaft LinTorque is obtained from the power sources such as engine and Certain rotating speed is produced, due to input shaft LinOn input gear ZinWith the gear Z on differential mechanism AAEngagement, input shaft LinBand Dynamic differential mechanism A rotations, differential mechanism A drive first axle L1With the second axle L2Rotation, due to first axle L1On first gear Z1With Three axle L3On the 3rd gear Z3Engagement, the second axle L2On second gear Z2With the gear ring B on planetary mechanism B1Engagement, then first Axle L1With the second axle L2Drive the 3rd axle L3With output shaft LoutRotation, so as to output shaft LoutProduce an output torque；
2nd, as output shaft LoutOn by less resistance and not less than critical value when, the buncher is from input shaft LinArrive LoutThe kind of drive it is constant, but now output shaft LoutOne and the 3rd axle L can be produced3Opposite torque, via planet machine Planet carrier B on structure B4Give gear ring B1One reverse active force, due to output shaft LoutOn the resistance that is subject to be not above facing Dividing value, then its give gear ring B1Opposition can not make gear ring B1Reversion, can only reduce gear ring B1Speed, and then So that second gear Z2Speed reduce, due to first gear Z1With second gear Z2Between differential mechanism A be present, differential mechanism A can Power is evenly distributed, in second gear Z2When speed reduces, then differential mechanism A can make first gear Z1Speed becomes big, and then makes the 3rd axle L3Speed become big, moment of torsion becomes big, so as to further increase central gear B2Moment of torsion, due to central gear B2With planet Frame B4On planetary gear B3Engagement, and then make output shaft LoutThe moment of torsion increase being subject to, overcomes output shaft LoutSuffered resistance Power；
3rd, as output shaft LoutOn by resistance more than critical value when, output shaft LoutGive gear ring B1Opposition can Make gear ring B1Reversion, but now, due in the second axle L2On one-way clutch C is installed so that the second axle L2It will not produce anti- Turn, therefore second gear Z2With gear ring B1It is static, and differential mechanism A can then give first gear Z1One twice ZASpeed, then Drive the 3rd axle L3Quick rotation, the torque transmitting after most increasing at last is to output shaft LoutUp.It is therefore, as long as reasonable in design, It after one-way clutch C is added, can avoid that the second gear Z as in the A of document CN 105370850 occurred occurs2Instead Situation about turning, can run with electrical automobile or other transmission devices in the case of larger resistance.
