In the utility model, input planet gear unit 2 and output planetary gear unit 5 are made of input sun tooth 2-1, input planet carrier 2-2, input gear ring 2-3 and output sun tooth 5-1, output planetary frame 5-2, output gear 5-3 respectively, jack shaft planetary gear unit 3 can be made of jack shaft sun tooth, jack shaft planet carrier, jack shaft gear ring, arbitraryly between them can be in transmission connection together by torque converter 4 to element, it is arbitrary selection of components is come according to the design needs of velocity ratio fixed.Jack shaft planetary gear unit 3 also can adopt common gear ring dual planetary gear to constitute, jack shaft planetary gear unit 3 shown in Fig. 1 is this structure, it is by jack shaft sun tooth 3-1 I, 3-1 II, and jack shaft planet carrier 3-2 I, 3-2 II and jack shaft gear ring 3-3 constitute.The concrete linkage structure of the utility model is, be packed in the output sun tooth 5-1 engagement in input gear 1 and the output planetary gear unit 5 on the input shaft 7, the input sun tooth 2-1 of input planet gear unit 2 and the output gear 5-3 of output planetary gear unit 5 engagement, the output planetary frame 5-2 of the input planet carrier 2-2 of input planet gear unit 2 and output planetary gear unit 5 is packed in respectively on input shaft 7 and the output shaft 9, the jack shaft planet carrier 3-2 I engagement of the input gear ring 2-2 of input planet gear unit 2 and jack shaft planetary gear unit 3, in the jack shaft planetary gear unit 3, its jack shaft sun tooth 3-1 I links to each other with the pump impeller 4-1 of torque converter 4 by jack shaft 8, the turbine 4-2 of torque converter 4 links to each other with jack shaft sun tooth 3-1 II, the guide wheel 4-3 of torque converter 4 links to each other with jack shaft planet carrier 3-2 II and complete machine housing, jack shaft gear ring 3-3 and output gear 6 engagements that are packed on the output shaft 9.
The utility model working procedure is as follows, on input shaft 7 is fallen in the motive force effect of mechanism system, when input shaft 7 is rotated by the diagram direction of arrow, it drives input gear 1 and input planet carrier 2-2 rotates together, the rotation of input gear 1 drives output sun tooth 5-1 and rotates synchronously, the rotation of input planet carrier 2-2 is by input gear ring 2-3 and input sun tooth 2-1 drives jack shaft planet carrier 3-2 I and output gear 5-3 rotates, and so just the motive force that the motive force machine is passed over resolves into three kinetic currents.The kinetic current that transmits on the planet carrier of falling the jack shaft 3-2 I drives the rotation of jack shaft sun tooth 3-1 I, the pump impeller 4-1 that the rotation of jack shaft sun tooth 3-1 I just drives torque converter 4 rotates, when the rotating speed of this pump impeller 4-1 reaches certain value, the turbine 4-2 that just drives torque converter 4 rotates, jack shaft sun tooth 3-1 II is rotated simultaneously, because jack shaft planet carrier 3-2 II is fixed, then the rotation of jack shaft sun tooth 3-1 II just drives jack shaft gear ring 3-3 rotation by the jack shaft planet wheel, the rotation of jack shaft gear ring 3-3 just drives output gear 6 and rotates, because output gear 6 is connected with output shaft 9, so the kinetic current that is delivered on the jack shaft planet carrier 3-2 I has passed to output shaft 9 by above-mentioned transmission.The aforementioned kinetic current that is delivered to the kinetic current on the output gear 5-3 and is delivered on the output sun tooth 5-1 is pooled on the output planetary frame 5-2, and is directly passed to output shaft 9.Like this, three kinetic currents of shunting are pooled to output in the lump on the output shaft 9 again on the input shaft 7.
In the device start stage, the rotating speed of input shaft 7 is lower, makes the pump impeller 4-1 turn up of torque converter 4 less than the tachometer value that drives torque converter 4 turbine 4-2, makes that output shaft 9 rotating speeds are zero, and the velocity ratio of this moment is zero.When the increase of equipment along with the rotating speed of prime mover, input shaft 7 rotating speeds are increased, then torque converter 4 pump impeller 4-1 rotating speeds increase thereupon gradually, and can drive torque converter 4 turbine 4-2 rotation, rotate thereby drive output shaft 9, and this moment, velocity ratio was a low value.Along with the rotating speed of prime mover further increases, the turbine 4-1 rotating speed of torque converter 4 further improves output shaft 9 rotating speeds also along with further raising, and velocity ratio increases gradually.When the rotating speed of prime mover reaches the turbine 4-2 rotating speed that makes torque converter 4 when the same with pump impeller 4-1 rotating speed, the velocity ratio maximum of this moment.To sum up, velocity ratio of the present utility model is along with the rotating speed of input shaft 7 progressively increases, and velocity ratio increases gradually by zero, up to maximum value, realizes the stepless variation of velocity ratio.
In actual applications, the rotating speed of output shaft 9 can make rotating speed reduce owing to be subjected to the influence of factors such as resistance, because the utility model is provided with torque converter 4, it just reduces velocity ratio automatically, thereby increases the moment of torsion of output shaft 9, realizes stepless deceleration.
