Embodiment Construction

[0024] figure 1 A schematic structural diagram of a hybrid transmission according to the first embodiment of the present invention is shown. As shown in the figure, the hybrid transmission has an electric motor EM, a motor shaft 1, a transmission input shaft 2, a transmission output shaft 3, a first synchronizer A, a second synchronizer B, and a third synchronizer C, respectively forming four The four sets of gear pairs Z11-Z21, Z12-Z22, Z13-Z23, Z14-Z24 of the transmission stage, which can be set in this way but are not limited to this setting: for example, in the internal combustion engine drive mode, Z11-Z21 is the first gear Gear pairs, Z12-Z22 are the second gear pair, Z13-Z23 are the third gear pair and Z14-Z24 are the fourth gear pair.

[0025] In this embodiment, the transmission input shaft 2 is connected to the internal combustion engine 4 via a clutch K0, which is preferably integrated in the housing of the electric machine EM. The motor shaft 1 connected to the e...

Abstract

The invention discloses a hybrid power transmission for a vehicle and the vehicle. The hybrid power transmission comprises a motor, a motor shaft, a transmission input shaft and a transmission outputshaft; and the hybrid power transmission is provided with a first transmission stage and a second transmission stage, wherein the first transmission stage comprises a first gear and a second gear which are meshed with each other, and the second transmission stage comprises a third gear and a fourth gear which are meshed with each other. The first gear and the third gear are arranged on the transmission input shaft in a loose mode, and a first synchronizer is arranged between the first gear and the third gear; and a second gear is arranged on the transmission output shaft in a loose mode, a fourth gear is arranged in an anti-torsion mode, a second synchronizer is arranged between the second gear and the fourth gear, and the second synchronizer can selectively connect the second gear with the transmission output shaft in an anti-torsion mode or in a neutral gear state, wherein the motor transmits torque to the first transmission stage through the motor shaft.

Description

technical field [0001] The invention relates to a hybrid transmission for vehicles, which comprises a first motor, a second motor, a transmission input shaft and a transmission output shaft, wherein an internal combustion engine is connected to the transmission input shaft through a clutch, and the first motor transfers the torque to the transmission input shaft, and the second electric machine transmits torque to the transmission output shaft. The invention also relates to a vehicle having a hybrid transmission as described above. Background technique [0002] In the current hybrid drive system, usually two electric motors need to be connected to the hybrid transmission, and the internal combustion engine is connected to the hybrid transmission through a hydraulic clutch, so that the hybrid transmission can realize multiple working modes, such as P2 mode (motor torque is directly sent to the transmission input), P3 mode (motor torque is directly sent to the transmission ou...
