Embodiment 1

[0016] see figure 1 , an integrated hybrid electric vehicle drive assembly, including an engine, a generator and an electric motor coaxially arranged in sequence; the crankshaft 2 of the engine is provided with a cantilever section extending toward the generator; the rotor 4 of the generator is fixed on the On the cantilever section; the shaft 8 of the motor is provided with an extension section extending towards the direction of the generator; a clutch 12 is provided between the extension section and the cantilever section; the housing 5 of the motor is provided with an extension section extending towards the direction of the engine ; The stator 3 of the generator is fixed on the extension; the casing 5 of the motor is fixedly connected with the casing 1 of the engine. The generator and the rotor shaft of the motor are connected or disconnected through a clutch.

[0017] In this embodiment, a two-cylinder water-cooled engine is used as the power source of the range-extending...

Embodiment 2

[0022] see figure 2 , an integrated hybrid electric vehicle drive assembly, the difference from Embodiment 1 is that a flywheel 12 is fixedly connected to the cantilever section of the crankshaft of the engine, the rotor 4 of the generator is fixed on the flywheel 12, and the generator The rotor 4 and the flywheel 12 are fixed together on the cantilever section of the crankshaft of the engine. Other structures are the same as in Example 1.

Abstract

The invention discloses an integrated hybrid power electric car drive unit, which comprises an engine, a power generator and a motor that are coaxially arranged in sequence; the rotor of the power generator is fixed to a suspension arm section; the shaft of the motor is provided with an extension section extended to the direction close to the power generator; a clutch is arranged between the extension section and the suspension arm section; the shell of the motor is provided with an extension section extended to the direction close to the engine; the stator of the power generator is fixed to the extension section; and the shell of the motor is fixedly connected with the engine. The integrated hybrid power electric car drive unit is compact in structure, convenient to mount, light in weight and low in cost, saves mounting space and can be directly mounted on the front cabin engine. For a drive mode, the integrated hybrid power electric car drive unit can realize independent drive of the motor, combined drive of the motor and the engine and combined drive of two motors and the power generator as the engine under the motor working condition, and provide higher drive power for a vehicle.

Description

technical field [0001] The invention relates to an automobile drive assembly, in particular to an integrated hybrid electric automobile drive assembly. Background technique [0002] At present, due to the increasingly stringent requirements for energy saving and emission reduction, the standards for energy saving and emission reduction of vehicles are also becoming stricter. In order to reduce the energy consumption of vehicles, many new vehicle systems including electric vehicles have been developed. Pure electric vehicles have the advantages of energy saving and environmental protection, and have gradually attracted the attention of major automobile manufacturers. An electric vehicle is a motor vehicle formed by replacing the engine with an electric motor on the basis of a traditional vehicle, and installing an energy storage system such as a power battery, a control system, and other auxiliary systems. However, the specific energy and charging speed of on-board energy s...
