Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, to be engine crankshaft 1 be connected with gear ring 2 among first planet row the utility model, first planet row, second planet row, the third line star row is joined by the gear ring 6 that is inserted in during the planet carrier 5 in the planet wheel 3 is arranged with second planet among first planet row respectively, sun gear 8 joins with planet carrier 13 in the planet wheel 11 that is inserted among the third line star row among second planet row, sun gear 4 among first planet row joins with driven shaft 14, be inserted in that the planet carriers 9 in the planet wheel 7 are fixed on the case of transmission 23 among second planet row, gear ring 10 among the third line star row is fixed on the case of transmission 23, second planet row, sun gear 8 among the third line star row, 12 are equipped with bearing fixing respectively on driven shaft 14, sun gear 12 among the third line star row by suspension axle sleeve 15 also with hydraulic couplers in pump impeller 16 link together, disk 18 with holes is fixed on the suspension axle sleeve 15, in the hole of disk 18, be plugged with extension bar 19, sliding bearing 20 links together by extension bar 19 and blade 17, turbine 21 is fixed on the driven shaft 14, pump impeller 16 equates that with the radius of turbine 21 end face is relative, pump impeller 16 and turbine 21 are contained in the hydraulic couplers housing 22, hydraulic couplers housing 22 is fixed on case of transmission 23, at hydraulic couplers housing 22 and disk 18, between the driven shaft 14 Sealing is housed.

A plurality of moving vanes 17 are arranged at position, pump impeller 16 rear end.

Arrange a plurality of blades 24 at turbine 21 front ends.

The working principle of three planet rows of the utility model and hydraulic couplers, engine crankshaft 1 is passed to gear ring 2 among first planet row with power, make the rotation of gear ring 2 clockwise directions, drive the rotation of planet wheel 3 clockwise directions, planet wheel 3 drives the rotation of planet carrier 5 clockwise directions, planet carrier 5 drives the gear ring 6 clockwise directions rotation among second planet row, gear ring 6 drives the rotation of planet wheel 7 clockwise directions, because planet carrier 9 is fixed on the case of transmission, planet wheel 7 forces sun human relations 8 rotation counterclockwise, sun human relations 8 drive planet carrier 13 rotation counterclockwise among the third line star row, because gear ring 10 is fixed on the case of transmission, planet carrier 13 forces planet wheel 11 clockwise directions to rotate, and planet wheel 11 drives sun gears 12 rotation counterclockwise, and this just makes pump impeller 16 counterclockwise rotate.

Planet carrier 5 during first planet is arranged connects pump impeller 16 by second, third planet row, and the effect that second, third planet queues is a rotational speed of accelerating pump impeller 16, also can how to arrange the rotational speed of accelerating pump impellers 16 with several planets.Mobile sliding bearing 20 drives blade 17 and moves, make blade 17 stretch out the distance of pump impeller when 2mm, the blade 17 of pump impeller drives the blade 24 that a spot of working solution is impacting turbine 21, turbine 21 and pump impeller 16 are rotated in the same way, this just makes driven shaft 14 rotation counterclockwise be fixed on the rotational speed that turbine 21 on the driven shaft 14 slows down planet carrier 5 among first planet row can for 16 1 fixing less reaction forces of pump impeller, planet wheel 3 among such first planet row just can drive sun gear 4 rotation at a slow speed counterclockwise, at this moment, the rotating speed of driven shaft 14 is slower, torque is bigger, has obtained low speed and has worked as velocity ratio.Mobile sliding bearing 20 drives blade 17 and moves, make blade 17 stretch out the distance of pump impeller when 5mm, the blade 17 of pump impeller drives the blade 24 that a large amount of working solutions is impacting turbine 21, making turbine 21 and pump impeller 16 rotate this in the same way just makes driven shaft 14 counterclockwise rotate, be fixed on the rotational speed that turbine 21 on the driven shaft 14 slows down planet carrier 5 among first planet row can for 16 1 fixing big reaction forces of pump impeller, planet wheel 3 among such first planet row just can drive sun gear 4 fast rotational counterclockwise, at this moment, the rotating speed of driven shaft 14 is very fast, torque is less, has obtained the top gear velocity ratio.The displacement distance of blade 17 described in the utility model is that the distance that 6mm, blade 17 stretch out pump impeller 16 all can obtain a fixed drive ratio on the arbitrary position between the 0-6mm, more than this transmission ratio, only need mobile sliding bearing 20 to drive blade 17 and can carry out gear ratio conversion once moving.Sliding bearing in this speed changer can directly be controlled by shift fork by shift handle, in order to alleviate motorist's work load, can set up the hyundai electronics sub controlling unit for this speed changer, realizes the safety automation of speed of a motor vehicle control.
