Problems solved by technology

[0005] However, although the transmission involved in the above application can also realize plug-in hybrid, the pure electric mode cannot realize the full working condition of the whole vehicle, and the engine still needs to be started for driving in high-speed working conditions, which is more suitable for deep hybrid models

Embodiment 1

[0060] Embodiment 1 A hybrid transmission

[0061] refer to figure 1 , this embodiment includes an internal combustion engine 1, a torque damper 2, a Ravina planetary system 21, a differential assembly 18, and also includes an outer ring gear 20 with the Ravina planetary system 21, an outer differential assembly Gear 22 meshes with the countershaft gear train. The input shaft is connected with the internal combustion engine through a torque damper.

[0062] The countershaft gear train is arranged between the Ravenna planetary system 21 and the differential assembly 18 .

[0063] The planet carrier 5 of the Ravenna planetary system 21 is connected with the input shaft through the first clutch 4 .

[0064] The Ravina planetary system 21 includes a front sun gear 13 , a rear sun gear 10 , a long planet gear 11 , a short planet gear 12 , and a planet carrier 5 . The inner hub of the first clutch 4 is connected with the outer hub of the second clutch 3 , and the outer hub of th...

Embodiment 2

[0103] Embodiment 2 A hybrid transmission

[0104] The structure diagram of this embodiment is shown in Figure 8 , the only difference in structure from Embodiment 1 is that this embodiment does not include the second clutch 3 .

[0105] The structure of other parts of this embodiment is the same as that of Embodiment 1.

[0106] Compared with Embodiment 1, this embodiment can also realize all the functions of the pure electric working condition in Example 1 after removing the second clutch 3. Although it does not have the functions of climbing steep slopes and rapid acceleration in hybrid working conditions, it can pass Although optimizing the motor power cannot meet the driving requirements of a full-featured SUV, it can meet the driving requirements of an ordinary car.

Abstract

The invention discloses a hybrid transmission, which comprises an internal combustion engine, a Ravina planetary system, and a differential gear assembly. The input shaft is connected with the internal combustion engine through a torque damper. Motor, the Ravenna planetary system has a second motor on the front sun gear. The present invention is improved on the basis of the existing 4AT of the Ravina-type planetary structure, so that it has a double EVT structure with a CVT-like continuously variable speed function, which can improve the shifting comfort of the electric working condition, and at the same time It can realize pure electric work under all working conditions of the whole vehicle, so it is especially suitable for plug-in hybrid vehicles. That is to say, all the functions of the electric vehicle can be realized completely by the power of the battery when the battery is not short of power. The present invention can effectively improve fuel economy, reduce fuel consumption, and improve shifting comfort at the same time. The invention is suitable for vehicles with front and front drive and transverse power assembly, and realizes hybrid drive.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to a vehicle transmission, in particular to a hybrid transmission. Background technique [0002] In recent years, due to considerations of energy saving and environmental protection, hybrid electric vehicles have become increasingly popular. The power source of a hybrid vehicle is an internal combustion engine and an electric motor. The low-speed and high-torque characteristics of the electric motor make up for the shortcomings of the internal combustion engine, especially the turbocharged internal combustion engine, which has insufficient low-speed torque, so that the power performance of the vehicle is fully guaranteed. The hybrid technology used in models of the same level can be matched with small-displacement engines without reducing power performance, and the fuel consumption rate and emission performance have also been greatly improved. [0003] Most car companies are trying to use ...
