Abstract

The invention discloses a power transmission system and a vehicle provided with the same. The power transmission system for a vehicle comprises an engine, an input shaft, an output shaft, a planetary gear mechanism and a first motor generator, wherein the input shaft comprises a first input shaft and a second input shaft, the engine is selectively connected with at least one of the first input shaft and the second input shaft, and the second input shaft is arranged on the first input shaft in a sleeving mode. An intermediate drive part is arranged between the output shaft and the input shaft. The planetary gear mechanism comprises a gear ring, a sun wheel and a planetary carrier, wherein the sun wheel is arranged on the first input shaft, and the second input shaft is connected with one of the gear ring and the planetary carrier. The first motor generator is connected with the other of the gear ring and the planetary carrier. The power transmission system is simple in control and structure.

Description

technical field [0001] The present invention relates to the field of vehicles, in particular to a power transmission system for a vehicle and a vehicle with the power transmission system. Background technique [0002] In the related art known to the inventor, the hybrid power transmission system is at least composed of an engine, a motor, a motor controller, and a planetary gear mechanism. The ring gear shaft and the sun gear shaft of the planetary gear mechanism are used as input shafts, and the two input shafts are respectively connected with the engine shaft and the motor shaft, wherein the planet carrier shaft is connected with the input shaft of the gearbox as a moment input shaft, Moreover, in order to realize pure electric drive and start the engine while driving, a one-way clutch is set on the engine shaft. The power transmission system can realize pure electric or parallel hybrid power output mode, but the power transmission system is only suitable for simple gearb...
