Abstract

The invention discloses a four-wheel drive hybrid power transmission device which has good vehicle power and passability and high fuel economy. The four-wheel drive hybrid power transmission device includes an internal combustion engine (1), a generator / motor I (2), a planetary gear row I (3), a clutch I (4), a clutch II (5), a planetary gear row II (6), a gear I (7), a gear II (8), a front driving wheel (9), a gear III (10), a gear IV (11), a clutch III (12), a generator / motor II (13), a clutch IV (14) and a rear driving wheel ( 15); the gear IV (11) is associated with the generator / motor II(13) by the combination and disengagement of the clutch III (12), and the generator / motor II (13) is associated with the rear driving wheel (15) through the combination and disengagement of the clutchIV (14).

Description

technical field [0001] The invention belongs to the technical field of power transmission devices of hybrid electric vehicles, in particular to a four-wheel drive hybrid power transmission device with good power performance and passability and high fuel economy. Background technique [0002] With the increasing depletion of oil resources and the increasing environmental pollution, countries have taken relevant measures to reduce emissions. It is estimated that by 2021, the EU's economical requirements will reach the level of 4.1L / 100km, and China will implement the National VI emission standard by then. Vehicle Fuel Consumption Evaluation Methods and Indexes" These two national mandatory standards require that the average fuel economy of new passenger cars be lower than 5L / 100km[1]. This makes the development of new energy vehicles an inevitable trend. [0003] As we all know, Sport Utility Vehicle (SUV) is very popular in China because of its good power and passability, a...
