Problems solved by technology

At present, there are many different schemes for the transmission system of hybrid electric vehicles, and each scheme has its own advantages and disadvantages. Generally speaking, the integration degree of the existing schemes is low, the weight and layout of the transmission system require a large space, and there are few operating modes. It is difficult to adapt to complex working conditions, and the efficiency of fuel and electric energy is low, which is not conducive to improving the power and fuel economy of the vehicle

Abstract

The invention discloses a multi-mode multi-gear four-wheel drive hybrid power transmission system which comprises a front drive system and a rear drive system. The front drive system comprises an engine, a front drive motor, a planetary line and a speed changer, the rear drive system comprises a rear drive motor, and the front drive motor and the rear drive motor are electrically connected with apower battery pack. The multi-mode multi-gear four-wheel drive hybrid power transmission system is compact in structure and high in system integration degree, various working modes can be realized bydifferent control strategies, and dynamic property and fuel economy of a vehicle under complicated working conditions can be effectively improved.

Description

technical field [0001] The invention relates to a multi-mode hybrid power transmission device, which belongs to the technical field of automobile power transmission devices, in particular to a multi-mode multi-gear four-wheel drive hybrid power transmission system. Background technique [0002] Under the pressure of energy and environment, new energy vehicles and other conventional vehicles have achieved development and progress. Among many new energy vehicle research and development, hybrid vehicles have the most practical value. At present, there are many different schemes for the transmission system of hybrid electric vehicles, and each scheme has its own advantages and disadvantages. Generally speaking, the integration degree of the existing schemes is low, the weight and layout of the transmission system require a large space, and there are few operating modes. It is difficult to adapt to complex working conditions, and the efficiency of fuel and electric energy is low,...
