Detailed description of the invention
The utility model, using blade-type pump as embodiment, although the oil-sealed rotary pump work structuring slightly difference that other this specification sheets is described to, does not affect principle explanation of the present utility model.
See Fig. 1, transmission gearbox 6 in diagram is the driving device of battery-driven car, its transmission gearbox input shaft 62 one end is connected with drive motor 7, arrange gear drive in transmission gearbox inner chamber body 63 to be connected with transmission case output shaft 61 and to realize Power output to wheel, the wheel brake cylinder 1 that wheel is connected by brake system master cylinder 2 realizes braking, the other end of transmission gearbox input shaft 62 is connected with vacuum pump 4 and realizes being integrated and connected of vacuum pump, 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 providing the vacuum servo of motor vehicle braking system, vacuum pump cavity 44 introduces lubricating oil from transmission gearbox inner chamber body 63, vacuum pump air extractor duct 42 is connected with transmission gearbox oil leab 5, and lubrication is sprayed in the circulation being realized transmission gearbox lubricating oil by the exhaust of vacuum pump.Concrete, the oil storage disc 64 that the suction muffler of vacuum pump cavity 44 is arranged by oil leab 45 and transmission gearbox inside is connected, lubricating oil can be got rid of when motor drives during transmission gearbox running, be provided with a custom-designed oil storage disc 43 in transmission case body the oil droplet got rid of is received, and be directed in vacuum pump, one comes lubrication for vacuum pump and sealing, also by vacuum pump, lubricating oil is arranged on some nozzles 51 of transmission gearbox inside simultaneously by transmission gearbox oil leab 5, needs the position of lubrication to carry out circulation to gear drive and bearing etc. and spray lubrication.
In the present embodiment, vacuum pump 4 selects vane-type vacuum pump, and it is installed on transmission gearbox body skin, and the vacuum pump rotor 43 that vacuum pump cavity 44 internal eccentric is arranged realizes power with transmission gearbox input shaft 62 and is connected.Air-inlet of vacuum pump 41 is by two unidirectional discharge chambers entering check valve 461 and vacuum pump inside of entering and suction muffler parallel communication, the discharge chamber of vacuum pump air extractor duct 42 and vacuum pump inside same by the discharge check valve 462 of two unidirectional discharges and suction muffler parallel communication, 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 reversing time, vacuum pump all can provide vacuum servo for vehicle.
Vacuum pump is when specific works, shown in Figure 2, two blades be connected with spring 47 are separated into A the selenodont space of vacuum pump cavity, B, C tri-parts, when rotor is by direction as shown left-hand revolution, the volume of the space A communicated with vacuum pump air suctiton inlet constantly increases, the pressure in A space constantly reduces, when the pressure in A space is lower than by the pressure taken out in container, according to the principle of gas pressure intensity balance, suction muffler A is constantly drawn into by the gas taken out, now be in breathing process, the check valve 461 that enters be communicated with suction muffler A provides vacuum in brake system master cylinder 2, the discharge check valve 462 be simultaneously communicated with suction muffler A ensures the air in transmission gearbox and lubricating oil to be sucked.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 communicated with vacuum pump air extractor duct 42 reduces further, the pressure in C space further raises, C space is discharge chamber, the lubricating oil that the gas of compression sucks in transmission gearbox together with the suction muffler of vacuum pump cavity 44 is together expelled to transmission gearbox oil leab from vacuum pump exhaust port, carries out sprinklings lubricate by the gear mechanism of nozzle 51 pairs of transmission gearbox inside and bearing.Contrary, if drive motor drives vacuum pump rotor 43 and blade 47 to rotate clockwise, A chamber then becomes discharge chamber, and C chamber becomes suction muffler, according to above-mentioned be arranged in parallel enter check valve and discharge check valve, vacuum pump can realize above-mentioned workflow equally.
In vehicle travel 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 rotate forward work or work because of other reason retrograde rotation, the transmission gearbox input shaft 62 of transmission gearbox 6 drives vacuum pump 4 to work, thus provide vacuum source for brake system master cylinder 2, chaufeur can be handled wheel brake cylinder 1 pair of vehicle and brakes by light hydraulic driving system master cylinder 2 by brake pedal 8, gas mixture in chamber is discharged from vacuum pump air extractor duct 42 by vacuum pump 4, flow in the transmission gearbox inner chamber body 63 of transmission gearbox 6 via transmission gearbox oil leab 5, and by nozzle 51, lubricating oil is sprayed onto gear and other keypoint parts not easily lubricated.Meanwhile, the lubricating oil splashed down during gear lubrication by atomization is flow 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 works, vacuum pump 4 can be driven to work, motor that need not be extra drives, such that structure is simple, dependable performance and saved cost; Meanwhile, vacuum pump rotates forward or retrograde rotation can normally work; In addition, the oil pumped by vacuum pump 4 is sprayed onto in transmission gearbox 6 by nozzle 51, gear and the keypoint part that wherein not easily lubricates is lubricated, improves lubricant effect.
