Abstract

The invention discloses a multi-gear driving device of a hybrid power vehicle. The multi-gear driving device of the hybrid power vehicle comprises an engine, a motor I, a motor II, a mechanical transmission, a main reducer, a torsional shock absorber and a differential mechanism. The engine, the motor I and the motor II are connected with the mechanical transmission through three transmission input shafts respectively, a driving gear of the main reducer is fixedly connected to a driven shaft of the mechanical transmission, a driven gear of the main reducer is connected with the differential mechanism, the mechanical transmission comprises the three transmission input shafts, the driven shaft, a meshing gear pair composed of six gears and four combination sleeves. Through the power source output mode and control over combination and separation of the combination sleeves, the motor I and the motor II can realize two-gear power output, the engine can realize four-gear power output, the driving capacity of the motor I, the motor II and the engine is developed to the maximum, and the motor I, the motor II and the engine are made to work in the regions with the highest efficiency respectively; no clutch is provided, so that the driving efficiency is high, no power failure exists in the gear shifting process and the dynamic property and the riding comfort are good.

Description

Technical field

[0001] The invention relates to the technical field of hybrid power vehicle transmission, in particular to a hybrid power vehicle multi-gear drive device. technical background

[0002] Today's automobile industry is facing tremendous pressure. With energy shortages and air pollution becoming more and more serious, various auto companies have launched energy-saving and environmentally friendly cars. Including pure electric vehicles and hybrid vehicles. Restricted by battery technology and charging technology, the driving range of pure electric vehicles cannot meet the needs of long-distance driving, and the requirements for supporting infrastructure such as charging stations are relatively high.

[0003] Compared with pure electric vehicles, hybrid vehicles do not need to change the infrastructure, can meet the requirements of long-distance driving, have less pollution, and the technology is relatively mature. It has become the best choice for auto companies to sol...

Embodiment 2

[0093] As an improved scheme of a hybrid vehicle multi-gear drive device provided by the present invention, if one more gear Ⅶ24 is connected to the transmission input shaft I15 of the aforementioned scheme, the idler gear Ⅷ25 on the driven shaft 5, such as Figure 7 As shown, gear Ⅶ24 and gear Ⅷ25 form a pair of meshing teeth. Gear Ⅶ24 is fixedly connected to the transmission input shaft I15 and is located between gear III2 and the coupling sleeve B16. Gear Ⅷ25 is empty sleeved on the driven shaft 5 and located in the coupling sleeve C4 and Combine between sets of D13. Similarly, the coupling sleeve C4 controls the engagement and disengagement of the gear Ⅷ25 and the driven shaft 5. In this way, on the basis of the original invention, the gears of the motor Ⅰ 20 and the motor Ⅱ 21 are increased by one, and the gear of the engine 22 is increased by two. , It is more beneficial for the engine 22 and the electric motor I 20 and the electric motor II 21 to work in the high-efficien...
