A hybrid power system and a vehicle using the hybrid power system

Abstract

Disclosed are a hybrid power system and a vehicle using same. The vehicle comprises a vehicle body provided with a hybrid power system and an axle (6). The hybrid power system comprises an engine (1), an electric motor (11), and a gearbox (3). A power output of the electric motor (11) is connected in a transmissive manner to a first driving shaft (13), a power output of the engine (1) is connected in a transmissive manner to a second driving shaft (12), the first driving shaft (13) is connected in a transmissive manner to the second driving shaft (12) via the gearbox (3), and the first driving shaft (13) and / or the second driving shaft (12) is connected in a transmissive manner to the axle (6) via a transmission mechanism. Also disclosed are a hybrid power system in which the transmission ratio between an engine and an electric motor is adjustable, and a vehicle using the hybrid power system.

Description

technical field [0001] The invention relates to a hybrid power system and a vehicle using the power system. Background technique [0002] Existing hybrid system such as Chinese patent CN102009587A discloses "hybrid device based on electromechanical transmission", the hybrid device includes an engine, a motor, a transmission and a first gear and a second gear for intermeshing transmission, wherein the engine passes The second transmission shaft is in transmission connection with the first gear, the motor is in transmission connection with the second gear through the first transmission shaft, the first gear is in transmission connection with the power input end of the gearbox, and the gearbox is used to output power to the corresponding axle. When working, the engine and the motor can be driven together or used separately according to the driving situation, and the engine will be automatically stopped when the vehicle stops to reduce energy consumption. The existing problems ...

AI Technical Summary

Problems solved by technology

The existing problems of this kind of hybrid power device are: 1. When the motor is used alone, the power of the motor is transmitted to the first gear through the second gear, and then transmitted to the corresponding axle through the transmission. The transmission stroke of this road is relatively long. And it must be driven by a gearbox, and the energy loss is relatively serious; 2. When the motor is required to charge the corresponding battery, the transmission ratio between the engine and the motor is fixed, which is not conducive to the optimal power generation of the motor, and is also not conducive to the optimization of the engine start up
