The utility model provides a kind of on-board air conditioner drive system, comprises driving engine, the first belt, compressor, and wherein the output of engine crankshaft front end is connected with the first belt, also comprises electrical generator, power source transition device, medium frequency electric motivation and overriding clutch.The flywheel of driving engine is connected with electrical generator, directly drags the alternating current of driving engine output frequency conversion voltage.The mouth of electrical generator is connected in the input end of power source transition device, the variable-frequency variable-voltage alternating current is converted to the intermediate frequency power supply of constant frequency and constant voltage through the power source transition device, the mouth of power source transition device is connected in the medium frequency electric motivation, to medium frequency electric motivation output intermediate frequency power supply, driving motor running.The medium frequency electric motivation is connected with the first belt by overriding clutch, guarantees that electrical motor can reversely not drag driving engine.Compressor is connected with the medium frequency electric motivation by the second belt, by its work of motor drives.
The input end of described power source transition device is by the external civil power of the first contactless switch, and external civil power provides intermediate frequency power supply for the medium frequency electric motivation by the first contactless switch after power supply changeover device is processed.
The port of described power source transition device is connected with the high-tension battery group, and the high-tension battery group provides intermediate frequency power supply for the medium frequency electric motivation after power supply changeover device is processed.
Described medium frequency electric motivation is by the external intermediate frequency power supply of the second contactless switch, and external intermediate frequency power supply directly provides intermediate frequency power supply for the medium frequency electric motivation by the second contactless switch.
The mouth of described power source transition device is connected to other consumers, for other consumers provide power supply.
The utility model is got on power-actuated basis at original machinery, and the electricity that has increased a/c system drives function.When the Mechanical Driven fault, the utility model is by Vehicular power system or the direct electric drive motor of various external source, then by the motor run compressor operating, make the mounted air conditioner system still can normal operation when there is mechanical breakdown in the associated components such as driving engine, realized the multi power source of on-board air conditioner drive system.Because electrical motor is connected with driving engine by overriding clutch, makes electrical motor can reversely not drag driving engine, guarantee system works safety.The bearing seat of driving engine links to each other by overriding clutch with the medium frequency electric motivation simultaneously, drives the idle running of medium frequency electric motivation, by the belt drive compressor, realizes the driving of a/c system during normal working of engine, makes the effective combination of Mechanical Driven and driven by power.

The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment:
The utility model provides a kind of on-board air conditioner drive system, comprises driving engine, the first belt, compressor, and wherein the output of engine crankshaft front end is connected with the first belt; The utility model also comprises belt pulley, electrical generator, power source transition device, medium frequency electric motivation and overriding clutch, driving engine is connected with electrical generator, the mouth of electrical generator is connected in the input end of power source transition device, the mouth of power source transition device is connected in the medium frequency electric motivation, the medium frequency electric motivation is connected with the first belt by overriding clutch, and compressor is connected with the medium frequency electric motivation by the second belt.The input end of power source transition device is by the external civil power of the first contactless switch.Power source transition device port is connected with the high-tension battery group.The medium frequency electric motivation is by the external intermediate frequency power supply of the second contactless switch.The mouth of power source transition device is connected to other consumers.
As shown in Figure 1, when the Mechanical Driven connection was broken down, the utility model switched to electric driving condition.Electrical generator is connected with the flywheel of driving engine, the alternating current of the direct drawing generator output of driving engine variable-frequency variable-voltage.The variable-frequency variable-voltage alternating current is converted to the constant frequency and constant voltage intermediate frequency power supply through the power source transition device, for driving the medium frequency electric engine operation, makes intermediate frequency motor drives compressor operating.Because the existence of overriding clutch, electrical motor can reversely not drag driving engine.The power source transition device is connected with the high-tension battery group simultaneously, be stored in the high-tension battery group behind the electric energy process power source transition device that driving engine produces, when the Mechanical Driven fault, within a certain period of time, the exportable variable-frequency variable-voltage alternating current of high-tension battery group, be converted to the constant frequency and constant voltage intermediate frequency power supply through the power source transition device, for driving the medium frequency electric engine operation, make intermediate frequency motor drives compressor operating.Simultaneously, the constant frequency and constant voltage intermediate frequency power supply of power source transition device output also can be used as the power supply of other vehicle-mounted consumers.When the vehicle Parking, external civil power is converted to intermediate frequency power supply by the first contactless switch through the processing of power supply changeover device, drive the medium frequency electric engine operation, the medium frequency electric motivation is by the second belt drive compressor operating, and external civil power is that direct supply is to high-tension battery group charge maintenance by the power supply changeover device rectification also; Simultaneously, external intermediate frequency power supply also can directly drive the medium frequency electric motivation by the second contactless switch, and the medium frequency electric motivation is by the work of the second drive compression machine;
