Embodiment 1

[0036] Hybrid transmission HT, such as image 3As shown in Table 1, it includes the first motor EM1, the second motor EM2, the shifting device SG, the power distribution integration mechanism DG, the transmission output mechanism TG, the casing 9, the input shaft 1, the second central shaft 2 and the fifth central shaft shaft 5; the first motor EM1 is equipped with a first rotor shaft RS1, and the second motor EM2 is equipped with a second rotor shaft RS2; the shifting device SG is a one-way clutch FC, and the one-way clutch FC has a one-way The function of power transmission; the power distribution integration mechanism DG includes the first planetary row PG1, and the first planetary row PG1 includes the first sun gear S1, the first ring gear R1, the first planetary carrier PC1 and the first planetary gear P1, the first planetary gear P1 is held on the first planetary carrier PC1, the first planetary gear P1 and the first sun gear S1 mesh with each other, the first planetary ...

Embodiment 2

[0060] Hybrid transmission HT, such as Figure 4 As shown in Table 1, its structure is similar to Embodiment 1, except that in Embodiment 2, the one-way clutch FC is arranged on the side away from the engine ICE in the axial direction.

Embodiment 3

[0062] Hybrid transmission HT, such as Figure 5 As shown in Table 1, its structure is similar to that of Embodiment 1, except that in Embodiment 3, the shifting device SG is the first brake B1; since the first brake B1 is used as the shifting device, the vehicle In the starting process, in addition to the second motor EM2 can be used alone, the first motor EM1 can also be used to drive alone, or the first motor EM1 and the second motor EM2 can be used to drive together; the vehicle has a higher starting speed in pure electric mode. Power, the vehicle can reach a certain speed under the joint drive of the first motor EM1 and the second motor EM2.

Abstract

The invention provides multiple hybrid power transmission devices (HT), and particularly provides a transmission device (HT) for various hybrid power vehicles. The transmission device (HT) comprises apower distribution integration mechanism (DG), and / or a gear shifting device (SG), and / or a motor (EM) and / or a speed changing output mechanism (TG). An engine (ICE) is connected with the power distribution integration mechanism (DG), and / or the gear shifting device (SG), and / or (EM) and / or the speed changing output mechanism (TG) through a torsion damping device (FW), and accordingly multiple purely-electric or hybrid power drive modes are achieved. Compared with the prior art, the transmission device (HT) is simple in structure, high in reliability, low in control difficulty and manufacturing cost and high in fuel economy.

Description

technical field [0001] The present invention relates to a variety of hybrid power transmissions, and in particular to a variety of transmissions mainly used in various hybrid power vehicles. Background technique [0002] Due to the aggravation of the world's environmental and energy problems caused by traditional fuel engine vehicles, and the increasingly stringent emission standards for vehicles in various countries around the world, major automobile companies are actively developing energy-saving and environmentally friendly vehicles. At present, the mainstream energy-saving and environment-friendly vehicles include pure electric vehicles and hybrid vehicles. However, due to the immaturity of the current battery technology, the initial cost of pure electric vehicles and the high cost of subsequent battery replacement, and the fast charging technology of pure electric vehicle batteries is very immature, so the hybrid system is currently the solution to vehicle energy consum...
