Hybrid vehicle driving device

Abstract

The invention provides a hybrid vehicle driving device, which mainly comprises an engine, a sun wheel, a planet wheel, a planet carrier, a gear ring, a sun wheel shaft, a public gear, a generator gear, a motor gear, a generator, a motor, a differential, a half shaft and wheels. A planet wheel system comprises the sun wheel, the planet wheel, the planet carrier, the gear ring and the like, and thesun wheel is in mechanical connection with the sun wheel shaft and the public gear and used for transmitting power between the generator or the motor and the planet wheel system. One-stage gear transmission is adopted between the generator and the sun wheel, so that the requirement of the system on the performance such as rotating speed, strength and the like of the generator is reduced while theoutput power of the generator is increased; therefore, technical difficulty and development cost are reduced; and gear meshing is adopted for power output, so that reliability and efficiency are high, transmission is stable, the defect of chain transmission is overcome, and the maintenance cost of the system is reduced.

Description

technical field [0001] The invention belongs to the technical field of hybrid power, and relates to a driving device of a hybrid electric vehicle, in particular to a driving device of a hybrid electric vehicle using a planetary gear train. Background technique [0002] Nowadays, people not only require the car to have sufficient performance and safety, but also put forward higher requirements for the fuel consumption and environmental protection of the car, that is, to require the car to have good power, maneuverability, comfort and safety at the same time , also require automobiles to reduce fuel consumption and emissions as much as possible, which makes hybrid vehicles the object of people's favor. [0003] In the existing hybrid technology, most of the drive devices of hybrid electric vehicles using planetary gear trains are very complicated in structure, and processing and assembly are also relatively difficult. The investment is not directly proportional, so it is diff...

Problems solved by technology

[0003] In the existing hybrid technology, most of the drive devices of hybrid electric vehicles using planetary gear trains are very complicated in structure, and processing and assembly are also relatively difficult. The investment is not directly proportional, so it is difficult to actually use it on the car in terms of structure and production
