Problems solved by technology

[0003] However, in the related 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

no. 3 Embodiment

[0132] According to the third specific embodiment of the present invention, it is substantially the same as the first specific embodiment, and for specific differences, refer to the following content. Such as Figure 13-Figure 18 As shown, in the axial direction of the central axis of the planetary gear mechanism P, the switching device adapter S is located on one side of the planetary gear mechanism P. Specifically, such as Figure 13-Figure 15 As shown, the conversion device adapter S is located on the right side of the planetary gear mechanism P in the axial direction of the central axis of the planetary gear mechanism P. Such as Figure 16-Figure 18 As shown, the conversion device adapter S is located on the left side of the planetary gear mechanism P in the axial direction of the central axis of the planetary gear mechanism P. In this way, in the axial direction, the planetary gear mechanism P and the conversion device adapter S are spaced apart, so that the arrangemen...

Abstract

Disclosed is a power train, comprising: a power source (100); a first motor-generator unit (300); a system power output portion (401); and a mode switching device (402), comprising a switching device input portion (4020), a first switching portion (4021a), a second switching portion (4021b) and a switching device output portion (4022). The switch device is connected to an input end of the system power output portion. An input portion of the switch device is adapted to output the power from at least one of the power source and the first motor generator unit. The switching device input portion is fixedly connected to a first switching portion. The switching device output portion selectively engages with the first switching portion or the second switching portion. The switching device output portion engages with the second switching portion, so as to be adapted to reduce the rotary speed output from the switching device input portion before outputting same to the input end of the system power output portion. In this way, driving modes of a vehicle can be enriched, and the vehicle can be adapted to different road conditions. Further disclosed is a vehicle having the power train.

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 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). The power and passing capacity of the whole vehicle are insufficient. Moreover, in order to realize the p...
