AI Technical Summary

Technical Problem

Conventional hybrid power trains for vehicles have complex structures, making them inconvenient to arrange and install, and occupy a large volume.

Method used

A hybrid powertrain with a simplified and compact structure, utilizing a converter, first motor, and engine that work together, allowing switching between different driving modes by selectively outputting power through a shared converter, and incorporating clutch assemblies and transmission members to connect to the front and rear axles.

Benefits of technology

The hybrid powertrain achieves improved driving performance by simplifying the structure, reducing volume, and enabling seamless switching between driving modes without the need for additional direction-changing gears.

Abstract

The hybrid powertrain (1000) includes a conversion device (10), a first motor (200), and an engine (300), and at least one of the first motor (200) and the engine (300) selectively outputs electric power to a driving end via the conversion device (10), and the engine (300) selectively outputs power to the first motor (200) via the conversion device (10) to drive the first motor (200) to generate electricity. The hybrid powertrain (1000) can realize various operating modes and has a compact structure. A vehicle (100) including the hybrid powertrain (1000) is also provided.
