- the motor is cooled by means of ambient air, which is fed from outside the rail vehicle by means of a motor cooling air line through a motor cooling air opening into the housing and directly to the motor, and / or the ambient air to be compressed by the compressor which is conducted from outside the rail vehicle to the compressor by means of a compressor intake line.
- a major advantage of the rail vehicle according to the invention is the fact that the cooling with ambient air or outside air provided according to the invention achieves better heat dissipation and better operating behavior can be, as in previously known rail vehicles, in which cooling with air from the engine room or Fahrzeu ginnenraums, that is, with indoor air;
- the invention is based on the inventor's finding that in the predominant operating situations the ambient air is cooler than the air in the engine room and can thus be cooled more effectively with the cooler ambient or outside air than with the indoor air.
- the air compressed by the compressor is preferably passed for cooling through the interior of a cooler which, in turn, is cooled from the outside with ambient air.

- Figure 1 components of a rail vehicle according to the invention, in which a double-shell housing forms a radiator cooling air line, an engine cooling air line and a line section of a compressor intake line,
- Figure 2 components of a rail vehicle according to the invention, which is equipped with two compressors and in which a two-shell or double-shell housing forms a radiator cooling air line, an engine cooling air line and a line section for compressor intake lines,
- Figure 3 components of a rail vehicle according to the invention, in which a double-shell housing a radiator cooling air line and an engine cooling forms air line and compressor suction lines are formed separately, and
- Figure 4 components of a rail vehicle according to the invention, in which a single-shell housing with a separately formeddeerkühlmaschinelei device, a separately formed engine cooling air line and separately formed compressor intake lines is connected.
- FIG. 1 shows an exemplary embodiment for a rail vehicle 10 which has a compressor 20, a motor 30 driving the compressor and a cooler 40 for feeding a compressed air system 11 on the rail vehicle side with compressed air D.
- the cooler 40 cools air K compressed by the compressor 20 before it is fed into the compressed air system 11.
- the compressor 20, the motor 30 and the cooler 40 are located in a housing 50 which contains the components 20,
- ambient air-based cooling measures are provided, namely ambient air-based cooling of the radiator 40, ambient air-based cooling of the motor 30 and an ambient air-based supply of the compressor 20.
- Ambient air U serves to cool the cooler 40 and is passed from outside of the rail vehicle 10 via a cooler cooling air line LI through a first opening 01 and through the cooler 40 into the interior of the housing 50.
- the cooler 40 can thus cool compressed air K produced by the compressor 20 is passed via the cooler 40 into the compressed air system 11 and is used there as compressed air D further.
- the motor 30 is cooled by means of ambient air U, which is fed into the interior of the housing 50 via a motor cooling air line L2 and a second opening 02, which thus forms a motor cooling air opening, and from there to the motor 30.
- the compressor 20 is supplied with ambient air U via a compressor intake line which, in the embodiment according to FIG.
- the air filter 60 is preferably arranged outside the housing 50 in order to enable simple maintenance or simple filter replacement.
- the filtered ambient air U passes from the air filter 60 via an output A of the air filter 60 to an input E of the compressor 20, specifically via a hose or a pipe, which is not shown in more detail in FIG. 1 for reasons of clarity.
- the hose or the pipeline forms a second line section L3b of the compressor suction line for the compressor 20.
- the housing 50 is double-walled and, in addition to an inner housing wall 51, has an outer housing wall 52; a cavity 53 is formed between the two housing walls 51 and 52.
- the cavity 53 of the double-walled housing 50 forms the radiator cooling air line LI in a first double-walled wall section W1, the engine cooling air line L2 in a second double-walled wall section W2 and the first line section L3a of the compressor intake line in a third double-walled wall section W3.
- the housing 50 has an air opening 50a, which is preferably connected to the roof via a fan 70 LOD of the rail vehicle 10 or a side wall 10s of the rail vehicle 10 is connected in terms of airflow.
- the housing 50 In order to allow the air to flow out of the interior of the housing 50 to the outside, the housing 50 preferably has an exhaust air opening 50b, which releases air from the interior of the housing 50, for example directly via the underframe 10u of the rail vehicle 10 to the outside.
- the double-walled design of the housing 50 leads to an advantageous synergy effect:
- the cavity 53 itself forms the three air lines LI, L2 and L3a, so that separate hoses or pipes for the relevant air guidance can be dispensed with.
- the double-walled structure leads to thermal insulation of the interior of the housing 50 from the interior 12 of the rail vehicle 10. In general, the ambient temperature outside the rail vehicle 10 is lower than the internal temperature in the interior 12 of the rail vehicle 10.
- thermal shielding of the interior of the housing from the interior 12 and the cooling with ambient air or with the air at ambient temperature can be achieved with a lower temperature inside the housing who than in the case of a single-shell construction of the housing 50 and a supply or cooling of the components 20, 30 and 40 with Air from the interior 12. It is also advantageously possible to feed the compressed air system 11 or to feed a further compressed air system, one or more further compressors 20 ', one or more further motors 30', one or more further filters 60 ', one or more more second line sections L3b 'for the compressor air intake and one or more additional coolers 40' to be provided.
- Such an exemplary embodiment is shown by way of example in FIG.
- the arrangement of the further compressors 20 ', the further motors 30' and the further coolers 40 ' is preferably chosen such that they lie on a common axis so that the openings 01' for the cooler 40 'and the openings 02' for the motor 30 'can each be diametrically opposite.
- the exemplary embodiment described in connection with FIGS. 1 and 2 is regarded as particularly advantageous, since the cavity 53 in the double-walled or double-shell housing 50 forms three lines, namely the cooler cooling air line LI, the engine cooling air line L2 and the first line section L3a of the Compressor suction line (s).
- the cavity 53 in the double-walled or double-shell housing 50 forms three lines, namely the cooler cooling air line LI, the engine cooling air line L2 and the first line section L3a of the Compressor suction line (s).
- Such configurations are shown by way of example in FIGS. 3 and 4.
- the first line section L3a of the compressor intake line is formed by a separate connection in the form of a hose or a pipe which connects the fan 70 directly to the air filters 60 and 60 '.
- radiator cooling air line LI the engine cooling air line L2 and the first line section L3a of the compressor intake lines are each designed as separate hoses or pipes.
- the housing 50 can have a double shell, as shown in FIGS. 1 to 3, or a single shell, as shown in FIG.
