Power transmission system for vehicle and vehicle

Abstract

The invention discloses a power transmission system and a vehicle with the same. The power transmission system comprises an engine, a first motor generator and a second motor generator; a first input shaft which is in power connection with the engine and the first motor generator respectively; a second input shaft which is in power connection with the second motor generator; an intermediate shaft which is selectively linked with the first input shaft and is linked with the second input shaft; a transfer mechanism which is linked with the first input shaft; and an output shaft which is selectively linked with the intermediate shaft and / or the transfer mechanism. According to the power transmission system, the intermediate shaft and the transfer mechanism are arranged, the intermediate shaft, the transfer mechanism and the output shaft are selectively connected to form a plurality of transmission paths which do not interfere with one another, and therefore different power sources can be used for compensating power interruption in the gear shifting process during gear shifting.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a power transmission system for the vehicle and the vehicle. Background technique [0002] In related technologies, with the development of hybrid technology, the fields that hybrid technology can be applied to are gradually increasing. Although the hybrid technology applied to cars is relatively mature, the load of cars is light, so it can be applied to cars. The gear position of the transmission system cannot be adapted to heavy-duty vehicles. In particular, hybrid power transmission systems applied to commercial vehicles have power interruptions when shifting gears. Power interruptions in heavy-duty vehicles will seriously affect the performance of the vehicle. Driving performance and safety. Therefore, under the background of gasoline-electric hybrid technology, how to develop a vehicle suitable for heavy-duty vehicles and how to solve the problem of power interruption during gear shi...

[0002] In related technologies, with the development of hybrid technology, the fields that hybrid technology can be applied to are gradually increasing. Although the hybrid technology applied to cars is relatively mature, the load of cars is light, so it can be applied to cars. The gear position of the transmission system cannot be adapted to heavy-duty vehicles. In particular, hybrid power transmission systems applied to commercial vehicles have power interruptions during gear shifting. Power interruptions in heavy-duty vehicles will seriously affect the performance of the vehicle. Driving performance and safety. Therefore, under the background of gasoline-electric hybrid technology, it is a technical problem in this field to develop a vehicle suitable for heavy-duty vehicles and how to solve the problem of power interruption during the shifting process.
