The fixed end of the carrier 21 and the overrunning clutch 5 are coupled to the fixed element, and the output large ring gear 23 is coupled to the input gear 25, and the input gear 25 is passed. The planet gears 20 on the input carrier 24 cooperate with the input carrier 24 and the output ring gear 26, the output ring gear 26 is coupled to the input pinion 27, and the input pinion 27 passes through the planet gears 20 and the output planets on the output carrier 28. Frame 28, input large gear 29 work together The output carrier 28 is coupled to the output shaft 3, and the output gear 72 of the output gear pair 7 is coupled to the input 41 of the multi-element working wheel torque converter 4, the output 42 of the multi-component working wheel torque converter 4 The output end 52 of the overrunning clutch 5 and the input gear 61 of the input gear pair 6 are coupled, the output gear 62 of the input gear pair 6 is coupled to the input carrier 24, and the input carrier 24 is coupled to the input bull gear 29.

The gear 29 then converges the power delivered thereto through the planet gears 20 on the output carrier 28 to the output carrier 28.

Since the speed distribution relationship of each of the above components can be changed, the two power flows will vary according to the change of the rotational speed distribution between the two. When the rotational speed of the input carrier 24 and the input bull gear 29 is zero, the input gear 25 and the input are small. The gear 27 is reduced in speed, and when the rotational speeds of the input carrier 24 and the input large gear 29 are continuously increased, the rotational speeds of the output ring gear 26 and the output carrier 28 also increase, that is, when the input carrier 24.

Input planet carrier 24, input large gear 29, and the input end 51 of the overrunning clutch 5 is coupled with the fixed component to limit the steering. The steering of the input carrier 24 and the input bull gear 29 cannot be reversed from the input steering, and the rotational speed is zero. At this time, the input gear is transmitted to the input gear. The power of 25 is transmitted to the output ring gear 26 through the planetary gears 20 on the input carrier 24, the output ring gear 26 is transmitted to the input pinion 27, and the input pinion 27 is passed through the planetary gears on the output carrier 28. 20 power is transmitted to the output planet carrier 28 and then to the output shaft 3. When the torque transmitted to the output shaft 3 is transmitted through the transmission system to the driving wheel, the traction force generated is sufficient to overcome the starting resistance of the vehicle, and the vehicle starts and starts. Acceleration, the rotational speed of the output end 42 of the multi-component working wheel torque converter 4 is also gradually increased, and the rotational speeds of the input input carrier 24 and the input large gear 29 are also gradually increased, thereby causing the output ring gear 26 to be outputted.

When the rotational speed of the input input carrier 24 and the coupled input gear 28 is zero, the ring gear 25 is coupled. When the input large ring gear 27 is used to reduce the speed and increase the torque, when the rotational speed of the input input carrier 24 and the input input gear 28 is continuously increased, the rotational speed of the output ring gear 26 and the coupled output carrier 29 also increases.
