Problems solved by technology

From US 5433282A is known an electromechanical hybrid system with a planetary gear set, an engine, an electric machine and a one-way clutch, however this system can only provide two modes of operation
[0005] Parallel hybrid systems have become more popular in recent years due to their high system efficiency. However, the arrangement of dual motors leads to increased system costs, increased integration difficulties, and increased control system complexity.
Dedicated hybrid systems (DHT) using a single electric motor are advantageous in terms of cost reduction, however at the expense of system performance and only have limited modes of operation
The solutions in the prior art all have rather complex dynamic coupling mechanisms, which increases the difficulty of manufacturing and integration and is not conducive to commercialization

Embodiment Construction

[0030] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, rather than to limit the protection scope of the present invention.

[0031] figure 1 A schematic diagram of a hybrid drive system according to a specific embodiment of the present invention is shown.

[0032] Such as figure 1 As shown, the hybrid drive system includes an engine 1, a motor 2, a first planetary gear set 3, a second planetary gear set 4, a shifter (GS) 5, a brake clutch (CB) 6 and a rotating clutch (CR) 7. Among them, the first planetary gear set 3 is mainly composed of the first ring gear 3R, the first planet carrier 3C and the first sun gear 3S, and the second plan...

Abstract

The invention relates to an electromechanical hybrid power coupling device, comprising: a brake clutch (6); a rotary clutch (7); fixed parts; a first planetary gear set (3) having a first ring gear (3R), a first planet carrier (3C) and a first sun gear (3S), wherein a mechanical power source is always connected to the first ring gear, a rotor of the electric machine is connected to the first sun gear, a rotary clutch is used to control connection or disconnection between the first ring gear and the first planet carrier, and a brake clutch is used to control connection and disconnection betweenthe first ring gear and the fixed member.

Description

technical field [0001] The invention relates to a hybrid power coupling device, a hybrid power drive system comprising the hybrid power coupling device, and a hybrid vehicle comprising the hybrid power drive system. Background technique [0002] As environmental protection measures around the world become more and more stringent, there are more and more alternatives to fuel engine vehicles, such as hydrogen energy vehicles, fuel cell vehicles, and hybrid vehicles. Hybrid cars currently have the most practical value. The hybrid drive system is classified according to the power transmission route, and can be divided into series type, parallel type, hybrid type (series-parallel), dedicated hybrid transmission (DHT) and so on. In a hybrid vehicle, a hybrid coupling may be used to transmit or couple the power of the engine and electric machine. [0003] Currently, a series hybrid system usually has two electric motors, one for engine speed modulation and the other for torque mo...
