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 first motor generator unit; a system power output part; a mode conversion device, and the mode conversion device includes: an input part and a planetary gear mechanism , an adapter and an output part, the output part is connected to the input end of the power output part of the system, the input part outputs the power from the power source and the first motor generator unit, the planetary gear mechanism includes first to third elements, the first The element is fixed to the input part, the second element is fixedly arranged, and the adapter is used to selectively engage one of the first element and the third element with the output part, and the output part is engaged with the third element, so as to be suitable for making the input part output a high speed The speed at the input end of the power output part of the system. In this way, the driving modes of the vehicle can be enriched, and 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
