Problems solved by technology

[0003] In related technologies, when the planetary gear train structure is adopted, the front planetary row is often used for power splitting, and the rear planetary row mechanism uses a Lavina or Simpson mechanism for speed regulation. There are many actuators, difficult planetary mechanism layout, low transmission efficiency and poor manufacturing process. High standard
[0004] When the parallel shaft structure is adopted, one of the electric motors is coaxially connected with the engine, and the other electric motor is used to drive the vehicle independently. In the pure electric mode, there is energy waste, and when the engine drives the vehicle alone, there are few gears to choose, and the fuel economy is low. and less fun to drive

Abstract

The invention discloses a power transmission system applied to a vehicle and the vehicle provided with the power transmission system. The power transmission system applied to the vehicle comprises a single-row single-stage planetary gear mechanism, an engine, a first motor, a second motor, a double-clutch transmission and an output shaft. The single-row single-stage planetary gear mechanism comprises a sun gear, a planet gear, a planet carrier and an annular gear. The output end of the engine is connected with the planet carrier. The first motor is connected with the sun gear. The output end of the second motor is connected with the input end of the double-clutch transmission. The output shaft is matched with the output end of the annular gear and the output end of the double-clutch transmission for transmission, so that power output by at least one of the engine, the first motor and the second motor is output to wheels of the vehicle. The power transmission system applied to the vehicle is simple and compact in structure, capable of realizing multi-gear output and high in fuel economy.

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 for a vehicle. Background technique [0002] A hybrid vehicle is powered by a small-displacement engine and two electric motors. The power drives the vehicle through the coupling of the gear assembly. The gear assembly for power coupling can be divided into two types: planetary gear train and parallel shaft type. Functions such as speed regulation and power splitting are realized by controlling the combination and separation of several clutches or brakes. [0003] In related technologies, when the planetary gear train structure is adopted, the front planetary row is often used for power splitting, and the rear planetary row mechanism uses a Lavina or Simpson mechanism for speed regulation. There are many actuators, difficult planetary mechanism layout, low transmission efficiency and poor m...
