Abstract
The utility model relates to a vacuum pump of an automotive brake system, in particular to an electrically-driven vacuum pump for a new-energy automobile, which comprises a base. A direct-current motor is mounted on the lower portion of the base, the vacuum pump driven by the direct-current motor is mounted on the upper portion of the base, an oilcan for storing lubricating oil is further mounted on the base, a pump body of the vacuum pump is provided with an air suction opening, an oil suction opening and an air and oil discharging opening, the oilcan is provided with an oil supplying opening and an oil returning opening which are connected with the oil suction opening and the air and oil discharging opening respectively, and the top of the oilcan is further provided with a vent. The electrically-driven vacuum pump for the new-energy automobile is compact in structure and light in weight, and capable of being controlled independently so as to not only save energy consumption, but also be better adapted to service conditions of the new-energy automobile. Moreover, the independent oilcan is used for supplying circulating lubricating oil, therefore, a lubricating oil system of the automobile is unaffected, and running reliability of a vehicular system is improved.
Description
Technical field
The utility model relates to a kind of vacuum pump of brake system of car, specifically is that a kind of new-energy automobile electricity drives vacuum pump.
Background technology
The employed vacuum pump of brake system of existing fuel oil power vehicle; Be generally an annex that is installed on the automobile current generator; It is by the generator shaft direct drive; Vacuum cylinder to Vehicular system vacuumizes, and also need utilize the negative pressure of epitrochoidal chamber circulation of the lubricating oil to be injected and the discharge epitrochoidal chamber in the working process.Existing this type of vacuum pump is as the annex of electrical generator, and volume is bigger, and can't directly apply to kind directly is the new-energy automobile of power with the electric energy; Simultaneously, it starts synchronously and stops with automotive engine, when degree of vacuum in the vacuum cylinder has reached requirement, still moves, and causes energy loss; In addition, its epitrochoidal chamber directly is connected the circulation that is lubricated oil with the lubricating oil system of automobile, and the quality to lubricating oil exerts an influence easily, and then can have a negative impact to the lubricated of other action components of vehicle.
Summary of the invention
The utility model technical matters to be solved is that the new-energy automobile electricity that a kind of compact conformation is provided, can independently control, energy consumption is low, internal lubrication does not influence the auto lubrication oil system drives vacuum pump.
The new-energy automobile electricity of the utility model drives vacuum pump and includes a pedestal, and the pedestal bottom is equipped with a DC machine, and pedestal top is equipped with a vacuum pump that is driven by DC machine, and the oil can that a storage has lubricating oil also is installed on the pedestal; The pump housing of vacuum pump is provided with air suctiton inlet, oil suction and the oil outlet of giving vent to anger, oil can be provided with respectively with above-mentioned oil suction with give vent to anger oil outlet bonded assembly oil-feed port and return opening, the oil can top also has air gate.
Said oil can is inner, is communicated with through a filtering installation between oil-feed port and the return opening.
The utility model compact conformation, in light weight; It adopts DC machine direct drive vacuum pump, and the starting state that can not receive automotive engine influences and carries out independent control according to the state of degree of vacuum in the vacuum cylinder, has not only practiced thrift energy consumption, and can adapt to the usage condition of new-energy automobile better; Oil can is its cycle lubricating oil because it adopts independently, therefore can the lubricating oil system of automobile not exerted an influence, and has improved the serviceability of Vehicular system.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan structure scheme drawing of Fig. 1.
The specific embodiment
As shown in the figure, this new-energy automobile electricity drives vacuum pump and includes a pedestal 1, and the pedestal bottom is equipped with a DC machine 2, and pedestal top is equipped with a vacuum pump 3 that is driven by DC machine, and the oil can 4 that a storage has lubricating oil also is installed on the pedestal; The pump housing of vacuum pump is provided with air suctiton inlet 31, oil suction 32 and the oil outlet 33 of giving vent to anger; The oil can bottom is arranged side by side oil-feed port 41 and return opening 42; Oil-feed port 41 is connected with the oil outlet 33 of giving vent to anger with above-mentioned oil suction 32 respectively with return opening 42, and the oil can top also has air gate 43.Inner at oil can, be communicated with through a filtering installation 44 between oil-feed port 41 and the return opening 42.
In the operational process; When vacuum pump vacuumizes; The lubricating oil of confessing from oil can 4 is drawn into epitrochoidal chamber from oil suction 32, and the action component of vacuum pump is lubricated, and gets back to oil can from the oil outlet 33 of giving vent to anger again; In oil can, filter through filtering installation 44, the gas of extraction is discharged by air gate 43.
Claims (2)
