Powertrain and vehicle having same

Abstract

The invention discloses a power transmission system and a vehicle thereof. The power transmission system includes: a power source; a transmission unit; a first motor generator unit including a first motor generator and a unit coupling; a switching module, a first motor The generator is connected to the speed change unit or the unit coupling part through selective power coupling through the switching module; the system power output part; the mode conversion device, the mode conversion device includes an input part and an output part, and the input part of the conversion device is respectively power-coupled with the speed change unit and the unit coupling part Connection, the output part is connected to the power output part of the system, and the input part and the output part are selectively connected by power coupling; when the input part of the conversion device and the output part of the conversion device are connected by power coupling, the speed of the input part of the conversion device is higher than or equal to that of the output part of the conversion device speed. In this way, the driving modes of the vehicle can be enriched, and the vehicle can adapt to different road conditions, which can improve the driving experience of the driver.

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
