The specific embodiment
The present invention is usingd blade-type pump as embodiment, although the vacuum pump work structuring that other this specification sheets is described to difference slightly does not affect principle explanation of the present invention.
Referring to Fig. 1, the driving device that transmission gearbox 6 in diagram is battery-driven car, its transmission gearbox input shaft 62 one end are connected with drive motor 7, in transmission gearbox inner chamber body 63, gear drive being set is connected with transmission case output shaft 61 and realizes power and export wheel to, the wheel braking cylinder 1 that wheel connects by brake system master cylinder 2 is realized braking, the other end of transmission gearbox input shaft 62 is connected and realizes being integrated and connected of vacuum pump with vacuum pump 4, realizes the power driven of vacuum pump.
The pipeline of concrete vacuum pump 4 connects as follows: air-inlet of vacuum pump 41 is connected with motor vehicle braking system master cylinder 2, and between be parallel with vacuum air storage tank 3, vacuum pump is driven by transmission gearbox by the drive motor of vehicle, for the vacuum servo of motor vehicle braking system is provided, vacuum pump cavity 44 is introduced lubricating oil from transmission gearbox inner chamber body 63,42 of vacuum pump air extractor ducts are connected with transmission gearbox oil leab 5, and the exhaust by vacuum pump realizes the circulation of transmission gearbox lubricating oil and sprays lubricated.Concrete, the suction muffler of vacuum pump cavity 44 is connected by the inner oil storage disc 64 arranging of oil leab 45 and transmission gearbox, when driving transmission gearbox running, lubricating oil can have been got rid of by motor, in transmission case body, being provided with a custom-designed oil storage disc 43 receives the oil droplet having got rid of, and be directed in vacuum pump, one carrys out the lubricated and sealing for vacuum pump, also can lubricating oil be arranged on by vacuum pump to some nozzles 51 of transmission gearbox inside by transmission gearbox oil leab 5 simultaneously, be circulated to spray in the lubricated position of the needs such as gear drive and bearing and lubricate.
In the present embodiment, vacuum pump 4 is selected vane-type vacuum pump, and it is installed on transmission gearbox body skin, and the vacuum pump rotor 43 of vacuum pump cavity 44 inner eccentric settings is realized power with transmission gearbox input shaft 62 and is connected.Air-inlet of vacuum pump 41 is communicated with discharge chamber and the suction muffler parallel connection of vacuum pump inside by two unidirectional check valves 461 that enter that enter, vacuum pump air extractor duct 42 is communicated with discharge chamber and the suction muffler parallel connection of vacuum pump inside equally by the discharge check valve 462 of two unidirectional discharges, as shown in Figure 2, vacuum pump is when drive motor drives transmission gearbox rotating, the position of its discharge chamber and suction muffler exchanges, the setting of this check valve can realize when drive motor rotating, and normal vehicle operation or when reversing, vacuum pump all can provide vacuum servo for vehicle.
Vacuum pump is when specific works, shown in Figure 2, two blades that are connected with spring 47 become A the selenodont spatial separation of vacuum pump cavity, B, tri-parts of C, when rotor is pressed direction as shown left-hand revolution, the volume of the space A communicating with vacuum pump air suctiton inlet constantly increases, the pressure in A space constantly reduces, pressure in A space is lower than the pressure of being taken out in container, according to the principle of gas pressure intensity balance, the gas of being taken out is constantly drawn into suction muffler A, now be in breathing process, the check valve 461 that enters being communicated with suction muffler A provides vacuum in brake system master cylinder 2, the discharge check valve 462 being communicated with suction muffler A guarantees the air in transmission gearbox and lubricating oil not to be sucked simultaneously.The volume in the space in B chamber reduces just gradually, and pressure constantly increases, and is now in compression process.And the volume of the space C communicating with vacuum pump air extractor duct 42 reduces further, the pressure in C space further raises, C space is discharge chamber, the gas of compression is together expelled to transmission gearbox oil leab from vacuum pump exhaust port together with the suction muffler of vacuum pump cavity 44 from the lubricating oil sucking in transmission gearbox, and the gear mechanism by 51 pairs of transmission gearbox inside of nozzle and bearing spray and lubricate.Contrary, if drive motor drives vacuum pump rotor 43 and blade 47 to clockwise rotate, A chamber becomes discharge chamber, and C chamber becomes suction muffler, and according to above-mentioned entering check valve and discharging check valve of being arranged in parallel, vacuum pump can be realized above-mentioned workflow equally.
In Vehicle Driving Cycle process, the vacuum pump rotor 43 of vacuum pump 4 is connected with the transmission gearbox input shaft 62 of transmission gearbox 6, when motor 7 drives transmission gearbox 6 to be rotated in the forward work or works because of other reason retrograde rotation, the transmission gearbox input shaft 62 of transmission gearbox 6 drives vacuum pump 4 work, thereby for brake system master cylinder 2 provides vacuum source, chaufeur can be braked by 1 pair of vehicle of light hydraulic driving system master cylinder 2 manipulation wheel braking cylinders by brake pedal 8, vacuum pump 4 is discharged the gas mixture in chamber from vacuum pump air extractor duct 42, via transmission gearbox oil leab 5, flow in the transmission gearbox inner chamber body 63 of transmission gearbox 6, and by nozzle 51, lubricating oil is sprayed onto to gear and other and is difficult for lubricated keypoint part.Meanwhile, the lubricating oil splashing down during gear lubrication by atomization flows in the vacuum pump cavity 44 of vacuum pump 4 through oil leab 45 by oil storage disc 64 again.Like this, when transmission gearbox 6 work, can drive vacuum pump 4 work, motor that need not be extra drives, and makes simple in structure, dependable performance and has saved cost; Meanwhile, vacuum pump is rotated in the forward or retrograde rotation can normally be worked; In addition, the oil being pumped by vacuum pump 4 is sprayed onto in transmission gearbox 6 by nozzle 51, makes gear and be wherein difficult for lubricated keypoint part to be lubricated, and has improved lubricant effect.
Although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention.Any those of ordinary skill in the art, in the situation that not departing from technical solution of the present invention scope, can utilize the technology contents of above-mentioned announcement to make many possible changes and modification to technical solution of the present invention, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solution of the present invention,, all should drop in the scope of technical solution of the present invention protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the technology of the present invention essence.
