Embodiment Construction

[0012] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. Such as figure 1 As shown, a motor / generator 13 booster drive system in a hybrid power system includes a power turbine reducer 15, a motor / generator 13, an engine 7, a two-stage turbocharger 5, an air collecting cover 1, three Combination 3, transmission 10, clutch 14, air filter 4, muffler 6, controller 12, battery 11 and other components. The power drive system is designed as a single-shaft parallel hybrid system. The torque of the motor / generator 13 is combined with the torque of the engine 7 through the transmission 10 before the transmission 8, and the power transmitted to the rear drive axle 9 is the two The sum is also the torque composite method. Its system design features and thermal flow are:

[0013] The shaft end at one end of the motor / generator 13 is connected with the power worm gear reducer 15 through the clutch 14 , and the shaft end a...

Abstract

The invention discloses a motor/power generator assisting drive system of a hybrid power system and belongs to the field of hybrid electric vehicles. The system connected to a power turbine speed reducer at the end of a motor/power generator shaft receives compressed gas generated from an engine turbocharger and ram air converged by a gas-collecting hood during high-speed running of a vehicle, drives a motor/power generator to rotate through expansion work of a power turbine, and serves as the motor/power generator assisting drive system of the hybrid power system. Compared with traditional hybrid power system, the hybrid power system with the motor/power generator assisting drive system has evident advantages of energy conservation and environmental protection. The motor/power generator assisting drive system is suitable for being mounted on a hybrid electric vehicle, and energy consumption and emission of the same can be lowered to a large extent.

Description

technical field [0001] The invention discloses a motor / generator booster drive system in a hybrid power system, which belongs to the field of hybrid electric vehicles. The system is mainly composed of a power turbine reducer connected to the end of the motor / generator shaft in the hybrid system, which receives the compressed gas generated by the engine turbocharger and the ram air formed by the confluence of the gas collection cover when the vehicle runs at high speed, and passes through the power The turbine expands to do work to drive the motor / generator to rotate, which becomes the motor / generator booster drive system in the hybrid power system. [0002] This kind of hybrid power system uses the internal combustion engine as the main power, and the motor / generator as the auxiliary power. Pressure booster drive. [0003] This technology has obvious energy-saving and environmental protection advantages compared with traditional hybrid power systems, and is suitable for bein...
