AI Technical Summary

Technical Problem

Existing hybrid systems have low transmission efficiency, especially since the engine and motor fail to operate in their efficient range under different operating modes, leading to increased fuel consumption.

Method used

It adopts a hybrid power system design that includes an engine, a first motor, a second motor, a clutch assembly, an input shaft, an output shaft, a differential, a gear transmission assembly, and a transmission gear pair. Through the control of the clutch and synchronizer, the power output control of the engine, the first motor, and the second motor is realized, supporting multiple working modes and gear switching, and ensuring that each component is always operating in the high-efficiency range.

Benefits of technology

It improves the transmission efficiency of the hybrid power system, enhances the vehicle's power and economy, and ensures driving comfort, while allowing for a smooth transition between different operating modes through seamless power switching.

Abstract

This invention discloses a hybrid power system comprising an engine, first and second motors, a first connecting shaft, first, second, and third clutches, first and second input shafts, an output shaft, a first motor connecting shaft, a differential, a gear transmission assembly, and a first transmission gear pair. The engine, first connecting shaft, and third clutch are connected sequentially, with the third clutch connected to both the first and second clutches. The first and second clutches are respectively connected to the first and second input shafts. The output shaft is loosely fitted around the first motor connecting shaft. The gear transmission assembly is connected between the first input shaft, the second input shaft, and the output shaft. The first motor is connected to the first motor connecting shaft, which is connected to the first connecting shaft via the first transmission gear pair. The output shaft is connected to one side of the differential, and the second motor is connected to the other side of the differential. This system ensures that the engine, first motor, and second motor always operate within their high-efficiency operating range, improving transmission efficiency and enhancing both power and fuel economy.
