Problems solved by technology

[0004] However, the drive system of the coaxial direct connection structure has high requirements on the output torque and rotational speed of the power source. The driving mode of the drive system of this coaxial direct connection structure is single, and the single drive mode will make the power source components It is difficult to allocate power reasonably, and it is also difficult to match a more efficient efficiency range, which leads to a decrease in power utilization and an increase in fuel consumption of power source components, and the emission reduction effect is not obvious

Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] figure 1 A schematic structural view of the power output device 10 of the present invention is schematically shown.

[0034] The power output device 10 of the present invention can be arranged between the engine 15 and the transmission shaft 16 (such as figure 2 As shown), it mainly includes a housing 13 and a first driving mechanism 11 and a second driving mechanism 12 arranged side by side inside the housing 13 . The first driving mechanism 11 is connected with the engine 15, so that the first driving mechanism 11 can generate electricity. The first driving mechanism 11 can also drive the transmission shaft 16 together with the engine 15 and the second driving mechanism 12. The second driving mechanism 12 is connected with the transmission shaft 16, and can drive the transmission shaft 16 alone, or can drive the transmission shaft together with the engine 15 16. ...

Abstract

The invention provides a power output device arranged between an engine and a transmission shaft; the power output device comprises a housing, a first driving mechanism and a second driving mechanism, and the first driving mechanism and the second driving mechanism are arranged in the housing side by side; the first driving mechanism is connected with the engine and is used for achieving a power generation function under the driving effect of the engine, or the first driving mechanism, the engine and the second driving mechanism drive the transmission shaft together; and the second driving mechanism is connected with the transmission shaft and is used for individually driving the transmission shaft, or the second driving mechanism and the engine drive the transmission shaft together, or the second driving mechanism, the engine and the first driving mechanism drive the transmission shaft together. The power output device is compact in overall structure, and the power transmission axial length is shortened. The invention also relates to a hybrid driving system comprising the power output device, with respect to the hybrid driving system, power sources can switch between different driving modes, a high-efficiency power combination can be achieved, and fuel economy is improved.

Description

technical field [0001] The invention relates to transmission technology, in particular to a power output device for providing power. The invention also relates to a hybrid drive system including the power output device. Background technique [0002] Nowadays, energy shortage and environmental deterioration are big problems facing the society. With the increasing awareness of environmental protection and rising oil prices, traditional fuel vehicles are also increasingly troubled by the shortage of oil resources. Therefore, energy conservation and environmental protection have gradually become the focus of the automotive industry. Theme of development. In recent years, a hybrid vehicle with two different power sources, low fuel consumption and low emission has been developed. It combines the advantages of pure electric vehicles and fuel vehicles. It has gradually become a hot spot for the development of major vehicle manufacturers. [0003] The applicant of the present inve...
