Embodiment Construction

[0029] figure 1A hybrid transmission according to a first preferred embodiment of the invention is shown. The hybrid transmission is used in a hybrid drive system with an internal combustion engine 1 and two separate electric machines. The two independent motors are the integrated starter generator 4 mainly used for speed regulation or as a generator and the traction motor 11 mainly used for towing the vehicle. In this preferred embodiment, the hybrid transmission has a first input shaft 3 connected to the internal combustion engine 1 (i.e. the internal combustion engine shaft 3), a second input shaft connected to the integrated starter generator 4 (i.e. the integrated starter generator shaft 5 ), an output shaft 14, a shifting device 6 and a set of planetary gear mechanism, wherein the planetary gear mechanism includes a planet carrier 9, a sun gear 7 and a ring gear 8. The internal combustion engine shaft 3 of the hybrid transmission, the planetary gear mechanism, and the ...

Abstract

The invention relates to a hybrid transmission and a vehicle. The hybrid transmission comprises a first input shaft connected with an internal combustion engine of the vehicle, a second input shaft connected with a motor of the vehicle, a gear shifting device, a planetary gear mechanism and an output shaft, wherein the internal combustion engine can transmit power to the planetary gear mechanism through the first input shaft and the gear shifting device, the motor can transmit power to the planetary gear mechanism through the second input shaft, and the planetary gear mechanism can transmit the power to the output shaft. According to the hybrid transmission and the vehicle, the gear shifting device is provided with a first end, a second end and a third end which are in anti-twisting connection with one another, wherein the first end is in anti-twisting connection with the first input shaft, the second end at least has a brake gear and a neutral gear, the third end is in anti-twisting connection with the planetary gear mechanism, and when the second end is in the brake gear, the second end is in anti-twisting connection with a shell of the hybrid transmission. The vehicle provided by the invention is provided with the hybrid transmission.

Description

technical field [0001] The present invention relates to a hybrid transmission comprising a first input shaft connected to an internal combustion engine of a vehicle, a second input shaft connected to an electric machine of the vehicle, a shifting device, a planetary gear mechanism and an output shaft. The invention also relates to a vehicle comprising a hybrid transmission as described above. Background technique [0002] In a current plug-in hybrid vehicle, two electric motors are connected to the hybrid transmission, and the internal combustion engine is connected to the hybrid transmission through a clutch, so that the hybrid vehicle can realize multiple working modes. On the one hand, however, both the traction motor and the combustion engine can only provide a single gear, which is not sufficient to optimize the operating point of the electric motor or the combustion engine. On the other hand, the clutch is engaged or disengaged according to the situation of the intern...
