Definitions
- the invention relates to an electric air pump for motor vehicles with a mounting plate which the housing of an electric motor and a pump are attached, and with a Silencer, through the mounting plate and a silencer cap attached is formed.
- Such an electric air pump is known from DE 41 09 548 C2.
- This well-known Air pump has a muffler cap that surrounds the electric motor, the Muffler space encircles the electric motor.
- the pump is an impeller pump, where the mounting plate forms the base plate of the pump chamber.
- This known electric air pump has disadvantages due to the arrangement of the Muffler around the electric motor is the outer diameter of this electric Air pump big. Nevertheless, the damping volume of the silencer is due to the Electric motor ultimately takes up little space.
- the outer diameter is determined by the arrangement of the muffler cap according to US 4,631,006 the electric air pump significantly reduced.
- the exchange of the Electric motor against another specimen with different external dimensions possible without this requires changes to the silencer cap.
- the silencer cap according to US 4,631,006 comprises the pump is between the Pump and the silencer cap no cable routing or chambering Manufacture of the silencer required. This measure also ultimately saves installation space and leads to the damping volume of the silencer even at low Outside dimensions of the silencer cap is large. This leads to a very effective one Sound absorption of intake and exhaust noises.
- This object is achieved in that the mounting plate in addition to the Holder for the motor shaft bearing a holder for the brush holder of the electric motor having.
- the electric air pump can advantageously be a vacuum pump with which a vacuum is produced.
- the mounting plate can have an inlet connector and / or have an outlet channel for the conveyed air, so that the silencer cap for Manufacture of such channels have no openings or pipe-like connecting parts got to.
- the mounting plate in the area of the outlet channel Have recess that together with a flange of the silencer cap Labyrinth forms to prevent unwanted moisture penetration, for example in the form of Avoid splashing water into the muffler's damping volume.
- the outlet channel is arranged below the pump and in this respect on the lowest point of the silencer opens into the silencer.
- the mounting plate can be particularly advantageous Have mounting flange on the attachment of the entire electric air pump a document. With this measure, it is not necessary to take appropriate measures Fastening parts to be provided in the area of the silencer cap.
- the mounting plate can particularly advantageously be made of metal, in particular aluminum, be die-cast, with the functional parts described in the inlet connection piece being particularly advantageous, Outlet duct, recess, mounting plate, receptacles for motor shaft bearings and brush holders can be integrally formed with the mounting plate. This also contributes to Simplification of the electric air pump and thus a reduction in manufacturing costs.
- the silencer cap can be made of metal and in the light metal die casting process or be produced as a deep-drawn part using the deep-drawing process.
- the pump can be a vane pump, particularly advantageously, the individual pump parts, base plate, rotor, ring and cover, in a known Are formed from a carbon-plastic mixture that the have particular advantage of high abrasion resistance and low friction.
- the Functional parts of the pump are then designed independently of the mounting plate so that the service life of the pump increases significantly compared to the known can be.
- the electric air pump has a mounting plate 1 on which a pot housing 10 of an electric motor is fastened by means of fastening screws 19 is.
- a pot housing 10 of an electric motor is fastened by means of fastening screws 19 is.
- an inlet connector 12 for the electrical Air pump which is designed as a vacuum pump for generating a vacuum
- an outlet duct 15 can be seen in FIG. 1 through which the practice the intake port 12 expelled air after passing through the pump becomes.
- the same or equivalent pump parts are provided with the same reference numerals as in FIG. 1.
- the inlet port 12 has a channel which is angled to the right in the area of the pump in Figure 2 and opens through a base plate 2 in the pump chamber de pump.
- This pump chamber of the pump is enclosed by the base plate 2, a pump rotor 4, a pump ring 5 and a cover 6 of the pump chamber.
- the pump rotor 4 is connected via a driver 3 to the motor shaft of the electric motor, which is enclosed by the pot housing 10.
- the entire pump consisting of the aforementioned parts, is connected to the mounting plate 1 with the screws 7 in such a way that the individual pump parts are clamped between the cover 6 and the mounting plate 1.
- the exhaust air from the vacuum pump flows into a damping volume Silencer 14, which is fixed by the mounting plate 1 and one Muffler cap 8 is formed, which comprises the pump.
- Silencer 14 After flowing through the Damping volume of the silencer leaves the pumped air Muffler through the outlet duct 15 which is arranged below the pump and which has a recess 16 which, together with a flange edge Muffler cap 8 forms a labyrinth.
- This maze is used for entry of splashing water into the damping volume of the muffler 14 is difficult and, on the other hand, is arranged in such a way that possibly forming Condensation in the damping volume of the muffler 14 through the pumped air is pushed out of the damping volume.
- the mounting plate 1 has a mounting flange 21 for mounting the entire electric air pump on a pad. Beyond that as more Functional parts of the mounting plate 1 a receptacle 17 for the pump side Motor shaft bearing and a receptacle 18 for the brush holder of the pump motor provided so that on the pump-side housing part of the electric motor can be dispensed with and its function both electrically and mechanically is taken over in full from the mounting plate 1.
- FIG. 3 shows the same or equivalent pump parts as in FIG. 1 and 2 with the same reference numerals as in Figures 1 and 2. you recognizes very well in Figure 3 the constructive mounting option of the electrical Air pump, in addition to Figures 1 and 2, the location and arrangement of the Outlet opening 13 of the pump, in the cover 6 of the pump and the inlet opening 20 of the Pump in the base plate 2 can be seen in the pump. It becomes clear that the channel of the inlet connector 12 both in its position and in its shape the position and shape of the inlet opening 20 is adapted. The through the Air outlet 13 of the cover 6, however, air can flow in the whole Damping volume of the silencer 14 within the silencer cap 8 spread to the outside via the recess 16 through the outlet duct 15 to pour. The entire structure of the electric air pump is very simple and inexpensive and allows both the use of different pumps in the Inside the muffler cap 8 and different dimensions Electric motors for the electric air pump.
