Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0014] see figure 1 A device for testing the dynamic performance of a hybrid electric power system, in the following three different embodiments, the implementation methods are as follows:

[0015] In the first embodiment, the acceleration performance test method of the hybrid electric system is as follows: start the heat engine 1 , the electric motor 9 and the loader 8 . The end of the heat engine 1 uses the electromagnetic clutch 2 to drive the upper end speed torque sensor 3, and the controller 12 fixes the output power of the loader 8 to a certain set value. When the speeds of the heat engine 1 and the electric motor 9 are stable, the controller 12 controls the heat engine 1 and the electric motor 9 to accelerate to a certain speed value a...

Abstract

The invention discloses a dynamical performance testing device for a petroleum-electricity hybrid power system. The output power of a heat engine and the output power of an electromotor are coupled through a gear box; the output ends of the heat engine and the electromotor are sequentially connected with the input end of an electromagnetic clutch and a speed-torque sensor; the output end of the gear box is connected with an output power adjustable loader; a controller controls whether the output power of the heat engine and the output power of the electromotor enter the gear box through the electromagnetic clutch; and acceleration sensors are arranged in the horizontal direction and the vertical direction of a first input shaft bearing seat of the gear box. The device can measure the acceleration performance and the deceleration performance of the petroleum-electricity hybrid power system and the vibration property of the system when the electromotor is connected and disconnected withthe hybrid power system.

Description

technical field [0001] The invention relates to a dynamic performance testing device of a hybrid power system, in particular to a dynamic performance testing device of an oil-electric hybrid power system. Background technique [0002] The gasoline-electric hybrid system is an important part of a hybrid vehicle, and it usually consists of a heat engine (diesel engine or gasoline engine), an electric motor, a power coupling device and a controller. The controller coordinates and controls the working state of the heat engine and the electric motor according to the actual working conditions: when the heat engine works in the fuel economy zone and the output power is greater than the load, the motor is disconnected; when the heat engine works in the fuel economy zone and the output power is less than the load , the motor is on. Due to the complex and changeable actual working conditions, the working state of the motor changes very frequently. As far as practical use is concerne...
