Title:
HYBRID POWER SYSTEM AND OPERATION MACHINERY
Document Type and Number:
WIPO Patent Application WO/2024/027139
Kind Code:
A1
Abstract:
The present application relates to the technical field of power apparatuses. Provided are a hybrid power system and operation machinery. The hybrid power system comprises: an engine, a clutch, a first electric motor, a second electric motor, an electric motor shell and a gearbox, wherein the gearbox is provided with a first input shaft and a second input shaft; the engine, the first electric motor and the second electric motor are coaxially arranged, the engine is connected to the first input shaft by means of the clutch, the first electric motor is connected to the first input shaft, and the second electric motor is connected to the second input shaft; and the first electric motor and the second electric motor are both arranged in the electric motor shell. The hybrid power system and the operation machinery provided in the present application can provide relatively large torque to overcome deficiencies in the power and torque of an engine, thereby meeting high-torque requirements, and avoiding or ameliorating an operation mode in which the engine works at a low level of efficiency; energy recovery can be implemented to achieve a relatively good braking effect and thus increase the rate of fuel saving; and the amount of space occupied is reduced, which facilitates installation and makes application to existing operation machinery easy, thereby reducing modification difficulties and costs.
