The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

Embodiment 1:

As shown in Fig. 1, a composite type relief valve external torque converter includes an input shaft 1, an output shaft 3, an overflow valve external torque converter 4, an overrunning clutch 5, and an input gear pair. 6. The output gear pair 7 is provided with a planetary gear 20, a fixed carrier 21, an input pinion 22, an output large ring gear 23, an output carrier 24, and an input ring gear 25 between the input shaft 1 and the output shaft 3. The input gear 26, the input carrier 27, the input small ring gear 28, the output ring gear 29, the input pinion 22 and the input gear 71 of the output gear pair 7 are coupled to the input shaft 1, and the input pinion 22 is fixed to the carrier 21 The planetary gear 20 cooperates with the fixed carrier 21 and the output large ring gear 23. The fixed end of the carrier 21 and the overrunning clutch 5 is coupled to the fixed component, and the output large ring gear 23 is coupled to the input ring gear 25, and the input ring gear is input. 25 cooperates with the output carrier 24 and the input gear 26 via the planetary gears 20 on the output carrier 24, the output carrier 24 is coupled to the input small ring gear 28, and the input small ring gear 28 is passed through the planetary gears 20 on the input carrier 27. Working in conjunction with the input carrier 27 and the output ring gear 29, The input carrier 27 is coupled to the input gear 26 and the output gear 62 of the input gear pair 6, the input gear 61 of the input gear pair 6 and the output 52 of the overrunning clutch 5 and the output of the external torque converter 4 of the relief valve 42 is coupled, the input end 41 of the relief valve external torque converter 4 is coupled to the output gear 72 of the output gear pair 7, and the output ring gear 29 is coupled to the output shaft 3.

The small ring gear 28 then converges the power transmitted thereto through the planetary gears 20 on the input carrier 27 to the output ring gear 29.

Since the speed distribution relationship of each of the above components can be changed, the two power flows will change according to the change of the rotational speed distribution between the two. When the rotational speed of the input gear 26 and the input carrier 27 is zero, the input ring gear 25 and the input are small. The ring gear 28 is reduced in speed. When the rotational speed of the input gear 26 and the input carrier 27 is continuously increased, the rotational speeds of the output carrier 24 and the output ring gear 29 also increase, that is, when the input gear 26 is input. When the rotational speed of the input carrier 27 changes, the rotational speeds of the output carrier 24, the output ring gear 29, and the output shaft 3 also change.

For the present invention, when the rotational speed of the input shaft 1 is constant, the torque on the output carrier 24, the output ring gear 29, and the output shaft 3 varies with the change of the rotational speed thereof, and the lower the rotational speed, the transmission to the output carrier 24 and the output teeth. The torque on the ring 29 and the output shaft 3 is larger, and conversely, the smaller, in the process, the external torque converter 4 of the relief valve also acts as a torque converter, thereby realizing the invention can travel with the vehicle.

The input gear 26, the input carrier 27, and the input end 51 of the overrunning clutch 5 are coupled to the fixed element to restrict the steering, so that the steering of the input gear 26 and the input carrier 27 cannot be reversed from the input steering, and the rotational speed is zero. At this time, the power transmitted to the input ring gear 25 is passed. The planet gears 20 on the output planet carrier 24 transfer power to the output planet carrier 24, the output planet carrier 24 is passed to the input pinion 28, and the input small ring gear 28 is then powered by the planet gears 20 on the input carrier 27. It is transmitted to the output ring gear 29 and then to the output shaft 3. When the torque transmitted to the output shaft 3 is transmitted to the drive wheel through the transmission system and the traction force generated is sufficient to overcome the starting resistance of the vehicle, the car starts and starts to accelerate. The rotational speed of the output end 42 of the external torque converter 4 of the flow valve is also gradually increased, and the rotational speed of the input gear 26 and the input carrier 27 is also gradually increased, thereby causing the output carrier 24 and the output teeth. The torque of the ring 29 and the output shaft 3 decreases as the number of revolutions increases.

The ring 27, the input large ring gear 28, converges the power delivered thereto to the coupled output planet carrier 29 by the planet gears 20 coupled to the output carrier 29.

Since the speed distribution relationship of each of the above components can be changed, the two power flows will change according to the change of the rotational speed distribution between the two. When the rotational speed of the coupling ring gear 25 and the input small ring gear 27 is zero, the input input carrier 24 is coupled. When the input large ring gear 28 is used to reduce the speed and increase the torque, when the rotational speed of the coupling ring gear 25 and the input small ring gear 27 is continuously increased, the rotational speed of the output ring gear 26 and the coupled output carrier 29 also increases, that is, It is said that when the rotational speed of the coupling ring gear 25 and the input small ring gear 27 changes, the rotational speeds of the output ring gear 26, the coupled output carrier 29, and the output shaft 3 also change.
