Power transmission system and vehicle with same

Abstract

The invention discloses a power transmission system and a vehicle with the same. The power transmission system comprises a power source, a first motor generator unit, a system power output part, a first pattern conversion device, and a second pattern conversion device. The power source and the first motor generator unit are connected or disconnected with the system power output part through the first pattern conversion device; the power source can be connected or disconnected with the first pattern conversion device through the second pattern conversion device, the second pattern conversion device comprises a conversion device input shaft, a first conversion device middle shaft and a conversion device output shaft, and the conversion device output shaft is connected with the first motor generator unit; the power from the power source is suitable to be transmitted to the first pattern conversion device after the speed of the power is reduced through the conversion device input shaft, the first conversion device middle shaft and the conversion device output shaft in sequence. In this way, driving patterns can be enriched, vehicles can adapt to varied road conditions, and the drivingexperience of drivers can be improved.

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
