Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments of the invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to the accompanying drawing that provides other accompanying drawing.
Fig. 1 is the structured flowchart that mixed motor-car is used power system in an embodiment of the present invention;
The corresponding relation of Fig. 1 component names and Reference numeral is:
The specific embodiment
Core of the present invention is for providing a kind of mixed motor-car power system and a kind of mixed electric bus, should be installed on this mixed electric bus with power system by mixed motor-car, mixed motor-car passes through to adopt the structure design of electronic control clutch with power system, can reduce the oil consumption of mixed electric bus, thus so that mixed more environmental protection and energy saving of electric bus.
In order to make those skilled in the art understand better technical scheme of the present invention, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, Fig. 1 is the structured flowchart that mixed motor-car is used power system in an embodiment of the present invention.
The invention provides a kind of mixed motor-car power system, comprise driving engine 1, electrical motor 2, speed change assembly 3 and power-transfer clutch 4, driving engine 1 is connected with speed change assembly 3 by power-transfer clutch 4 with electrical motor 2.According to the requirement of automobile speed speed change, in power system, also include the speed change assembly 3 that carries out speed change.Those skilled in the art as can be known, power-transfer clutch is driving and driven part transferring power or when motion on coaxial line, has to engage or the device of separation function.Generally speaking, in the clutch bell of power-transfer clutch 4 between driving engine 1 and speed change assembly, with screw power-transfer clutch 4 assemblies are fixed on the back plane of flywheel, the output shaft of power-transfer clutch 4 is exactly the input shaft of change speed gear box.In vehicle traveling process, power-transfer clutch 4 can make driving engine 1 and change speed gear box temporarily separate and engage gradually, to cut off or to transmit driving engine 1 to the power of change-speed box input.
In said structure, this power system is owing to having comprised driving engine 1 and electrical motor 2, can be so that the present invention has advantages of hybrid vehicle, that is: the fuel-economy performance of hybrid vehicle is high, and rideability is superior, and the driving engine of hybrid vehicle will use fuel oil, and in starting, when accelerating, owing to the auxiliary of electro-motor being arranged, so can reduce oil consumption.In order further to reduce oil consumption of the present invention on the said structure basis, power-transfer clutch 4 adopts electronic control clutch in the present embodiment.
Electronic control clutch (EZmatic) is the cover Intelligent clutch control system for the manual gear automobile development.Electronic control clutch is controlled power-transfer clutch 4 by controller, cooperates throttle to finish oily from cooperation.Controller in conjunction with driver's operation intention, sends the order-driven executive device according to transducing signals such as the speed of a motor vehicle, engine speed, each pedal position, buttons, reaches the purpose of clutch driving disc separation or combination, and easily realization is oily from cooperation, accelerates shift speed.Adopt electronic control clutch, owing to can save oil consumption for electron steering, and in the situation that automobile is put into gear, also can not stop working, avoid oil consumption increase and the idle operation of engine starting.Therefore, the present invention can further reduce the fuel oil consumption of mixed motor-car by adopting electronic control clutch.
