Embodiment 1

[0041] Such as figure 1 As shown, a hybrid drive system as a whole includes three main components of a hybrid transmission engine 17 and a motor 18 . in:

[0042] The engine 17 is connected to the ring gear 24 of the hybrid transmission.

[0043] The electric machine 18 is connected to an intermediate shaft 21 of the hybrid transmission.

[0044]Further, on the basis of the above-mentioned embodiments, a torsion-limiting shock absorber 20 is also provided between the ring gear 24 and the engine 17, and the torsion-limiting shock absorber utilizes disc springs, friction plates, splined hubs, etc. to transmit the torque of the engine 17 When the torque is overloaded, it relies on slipping between the friction surfaces to prevent the transmission system from being overloaded and damaged. At the same time, an arc spring torsional shock absorber is installed inside, which can attenuate the large torsional vibration angular acceleration at the flywheel end of the engine 17 to the ...

Embodiment 2

[0094] Based on the same inventive concept, the present invention also provides a vehicle, including any one of the hybrid drive system in Embodiment 1. Specifically, in this hybrid vehicle, the structure of the hybrid transmission adopts the above embodiment Except for the medium hybrid gearbox, the structure, connection relationship, installation position, etc. of other devices can refer to the relevant disclosures of the prior art, and no further description will be made here.

Abstract

The invention discloses a hybrid power gearbox, a hybrid power driving system and a vehicle. The hybrid power gearbox comprises a box body, a single planet row, an intermediate shaft, a parallel gear set, an output transmission mechanism and seven executing mechanisms, and the first executing mechanism is selectively connected with a first parallel gear or a second parallel gear; the second actuating mechanism is selectively connected with the planet carrier or the box body; the third executing mechanism is selectively connected with the third parallel gear or the fourth parallel gear; the fourth executing mechanism is used for connecting or disconnecting the seventh parallel gear and the intermediate shaft; the fifth executing mechanism selectively connects or disconnects the fifth parallel gear and the output gear; a sixth executing mechanism selectively connects or disconnects a sixth parallel gear and the output gear; according to the invention, power output by the engine and the motor is distributed and guided through the plurality of executing mechanisms and the plurality of parallel gears, so that multi-gear output under the premise of dual power of the engine and constant-speed-ratio output of a planet row are realized.

Description

technical field [0001] The present application relates to the technical field of hybrid vehicles, in particular to a hybrid transmission, a hybrid drive system and a vehicle. Background technique [0002] A hybrid vehicle refers to a vehicle equipped with more than two power sources, such as batteries, fuel cells, solar cells, internal combustion engines, motors, etc. Currently, a hybrid vehicle generally refers to a hybrid driving form in which the power source is an internal combustion engine and an electric motor. [0003] At present, there are mainly three types of power structures for hybrid electric vehicles. One is a series structure, one is a parallel structure, and the other is a mixed structure. The parallel structure is mainly driven by the engine, and uses the characteristics of the motor to generate strong power when starting. When the fuel consumption of the engine is large such as starting and accelerating, the motor is used to assist the drive to reduce the ...
