Problems solved by technology

Traditional medium- and heavy-duty vehicles usually have a complex structure and take up a lot of space due to the large range of transmission ratios and multiple gears
Combining the dual-clutch automatic transmission system with the development of hybrid electric vehicles, General Motors of the United States has done research in this area, but the hybrid electric vehicle transmission system designed has many working modes, but it does not use a planetary gear mechanism, which makes the structure complicated. not compact
Beijing Institute of Technology, in its patent application No. 200310115399.X, proposed a hybrid vehicle drive system that combines a planetary gear mechanism with other transmissions, but its structure is not only complicated, but also the planetary gear mechanism is simply connected

Embodiment Construction

[0020] combined with figure 1 Shown hybrid electric vehicle transmission system is described as follows to each mode of work of the present invention:

[0021] 1). The motor starts the internal combustion engine mode

[0022] At this time, no matter the car is in the parking state or the pure electric driving state, as long as the first clutch 2 or the second clutch 3 is engaged, the internal combustion engine can be started with the electric motor as the power source.

[0023] 2).Internal combustion engine driving mode

[0024] I. First and fifth gear drive of internal combustion engine

[0025] In the transmission system for a hybrid vehicle according to the present invention, the first clutch 2 is controlled to be engaged, the second clutch 3 is disengaged, and the second synchronizer 23 is engaged with the first-speed driven gear 22 (or the third-speed driven gear 24 ). At this time, the planetary row plays a decelerating role, and the speed ratio is q. The power trans...

Abstract

The present invention relates to a double-clutch hybrid power automotive transmission system. It includes the following several portions: internal combustion engine, two clutches, motor rotor, motor stator, four-gear double-clutch automatic speed changer, epicyclic gear train mechanism and output end. Said invention also provides the connection mode of all the above-mentioned portions and working principle of said hybrid power transmission system.

Description

technical field [0001] The invention relates to a transmission system of an automobile, in particular to a transmission system of a hybrid electric vehicle. Background technique [0002] With the world's energy shortage and the enhancement of people's awareness of environmental protection, safety, energy saving and environmental protection have become the themes of automobile development. At the same time, due to the bottleneck of key technologies of pure electric vehicles and fuel cell vehicles, hybrid vehicles have become a timely choice. This option can achieve more satisfactory results. [0003] At present, the development of domestic hybrid vehicles mainly focuses on the development of urban buses and cars, and the penetration of hybrid development into other medium and heavy vehicles has not yet been involved. Traditional medium- and heavy-duty vehicles usually have a complex structure and take up a lot of space due to the large range of transmission ratios and multip...
