Power transmission system and vehicle with same

Abstract

The invention discloses a power transmission system and a vehicle. The power transmission system includes a system power output part, a power source, a first motor generator unit and a mode conversiondevice; the first motor generator unit comprises a first motor generator and a unit coupling part, the unit coupling part is connected with an input end of the system power output part of the vehicle, and the first motor generator is selectively connected with the unit coupling part; the mode conversion device comprises an input part, a first conversion part, a second conversion part and an output part, the input part is selectively connected with the power source, the first conversion is connected with the input part and is selectively connected with the output part, the second conversion part is selectively connected with the input part and the output part, the output part is selectively connected with the unit coupling part and connected with the first motor generator, and therefore power output by the power source is suitable for being subjected to speed reduction through the input part and the second conversion part of the conversion device in sequence and output. In this way, the vehicle can adapt to different road conditions.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a power transmission system of a vehicle and a vehicle with the power transmission system. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. As one of the new energy vehicles, a hybrid vehicle is driven by an engine and / or an electric motor, and has multiple modes, which can improve transmission efficiency and fuel economy. [0003] However, in the related technologies known to the inventor, some hybrid electric vehicles have few drive modes and low drive transmission efficiency, which cannot meet the requirements of the vehicle to adapt to various road conditions, especially after the hybrid electric vehicle is powered (when the battery power is insufficient). The power and passing capacity of the whole vehicle are insufficient. Moreover, in order to realize the...

[0003] However, in the relevant technologies known to the inventor, some hybrid electric vehicles have few driving modes and low drive transmission efficiency, which cannot meet the requirements of the vehicle to adapt to various road conditions, especially after the hybrid electric vehicle is fed (when the battery power is insufficient). Insufficient vehicle power and passing capacity

Moreover, in order to realize the parking power generation condition, it is necessary to additionally increase the transmission mechanism, which has low integration and low power generation efficiency
