- the cooling circuit comprises a cooler, which is followed by a fan and upstream of a sieve.
- a backwash tube is arranged, which has a plurality of backwash openings, which are aligned towards the screen.

- the backwash tube is arranged on a rotatably mounted shaft, so that a permanent segment-wise backwashing of the screen is possible by turning the backwash tube.
- two blades are rotatably connected to the shaft, which are arranged in the suction air flow of the fan downstream of the screen and thereby drive the shaft rotating.
- two cover blades are non-rotatably connected to the shaft, which are arranged upstream of the screen and run after the backwash pipe, to avoid an immediate re-sucking the backwashed impurities.
- the cooler is associated with a cleaning device.
- the cleaning device operates with compressed air, which arranged on the upstream of the radiator, stationary or adjustable distribution strips with outlet openings to the radiator to blow away attached thereto impurities from the radiator or Blow through the radiator.
- the outlet openings may be designed so that the compressed air emerges vertically or inclined to the plane of the cooler.

- a device according to the approach presented here can be operated with energy sources present on the vehicle and be simple and robust so that it does not itself need to be the subject of intensive maintenance work.
- the inventive approach When used in rail vehicles, the inventive approach has the advantage that compressed air is already available, since it is used in almost all rail vehicles in the brake system. A control can be done via low-maintenance solenoid valves.
- the streamlined shape and preferably small diameter of the tubes allow a small depth, since the cooling air flow is only slightly hindered. Furthermore, excessive soiling can not lead to clogging, damage or other failure of the devices of the invention. These can be inexpensively manufactured even with small quantities and retrofitted to existing vehicles.
- the approach of the invention takes into account the problem that modern electric and diesel-powered multiple unit trains are characterized by increasing performance and high air demand for the cooling of the drive components, while at the same time there is a desire of the operator of the traction units for the longest possible maintenance intervals.
- the approach presented here can contribute to the fact that these two situations no longer regularly lead to a conflict of goals, e.g. when in summer the cooling air in some areas has a high proportion of light plant fibers such as poplar, dandelion, etc.
- underfloor cooling systems which are arranged under the car floor, the fibers deposit at the radiator inlet and can significantly hinder the air flow through the radiator.
- the required cooling capacity can be restored without the need to manually extract the fiber residues on the air inlet side of the cooler depending on the weather and field of use up to once a day.

- the invention is based on the general idea of coupling the air filter with a vibrator which vibrates the air cleaner for cleaning.
- a vibrator which vibrates the air cleaner for cleaning.
- the impurities deposited on the air filter can be loosened, so that they can fall down due to gravity.
- this may be the air filter with vibratory attachment points held on a corresponding frame.
- elastomer mounts are suitable for fastening the air filter to the frame.
- a further embodiment is advantageous in which the air filter is located in an air filter plane, whose normal direction is inclined relative to the main direction of the cooling air flow, for example in an angular range of 15 ° to 60 °, preferably 15 ° to 30 °.
- the present invention thus provides in particular a device for cleaning an air filter of a vehicle, comprising: a backwashing device comprising a pipe device with a connection for supplying compressed air and a plurality of nozzles for discharging the compressed air in the direction of the air filter to clean the air filter , And a vibration device for vibrating the air filter to clean the air filter.
- the respective device for cleaning can be arranged for example on a trainset of a rail vehicle or on a wagon of a rail vehicle.
- the device can be used for cooling a drive of the rail vehicle and, alternatively or in addition to the interior cooling of the rail vehicle.
- the compressed air can be applied through the nozzles on a side facing the nozzles of the air filter, so that, for example, plant fibers can be lifted on the side facing away from the nozzle air filter and fall to the ground.
- the air filter can be acted upon, for example, by wind with outside air.
- the air filter can be a fine-meshed nonwoven or a grid that is suitable for filtering out eg fibrous materials of different sizes from the outside air.
- the device may be arranged downstream of the air filter in the flow direction of the air flow to be cleaned by the air filter.
- the tube device may, for example, have one or more interconnected round tubes, which can be traversed by the compressed air.
- the nozzles may be formed through openings in the tube means, so that the compressed air passing through the tube means may be discharged through the nozzles to pressurize the air filter.
- the connection for supplying the compressed air to the tube device may be arranged in the one round tube or one of the plurality of round tubes.
- the connection may be, for example, a valve, in particular an impulse valve, via which the time and duration of the discharge process can be controlled.
- the connection can be connected directly or indirectly via another connection to a compressed air line of the vehicle.
- the device may comprise a frame element with a compressed air connection for connecting the frame element to a compressed air line.
- the frame member may be configured to receive the tube means so that the compressed air port can be connected to the port of the tube means.
- the frame element may be e.g. to act a stable rectangular construction, which is adapted to accommodate the one frame member and the other the air filter.
- the frame member may advantageously be formed as a sealing frame, which can receive the air filter so that no plant fibers can penetrate past the edges of the air filter in the device and the interior of the vehicle and can affect the function of the radiator, for example.
- the tube means may comprise a plurality of adjacently disposed tubes and two manifold tubes for receiving opposite ends of the plurality of tubes.
- the plurality of tubes may have the plurality of nozzles.
- the tubes may be arranged parallel to each other.
- the nozzles can be evenly distributed over an entire length of the tubes.
- the distribution pipes may have a larger diameter than the pipes, so that the compressed air can be easily and quickly distributed to the pipes.
- Such a configuration of the pipe device has the advantage that the compressed air can be applied uniformly and over the entire surface of the air filter and this can be cleaned so evenly.
- the plurality of nozzles may each be disposed on a side of the plurality of pipes facing the air cleaner.
- the nozzles are aligned against the airflow coming from the outside, so that an efficiency of the cleaning by means of compressed air is optimal.
- a nozzle jet direction of the nozzles with which the nozzles radiate the compressed air in the direction of the air filter, with respect to a normal direction of a plane in which the air filter extends, is inclined, for. in an angular range of 15 ° to 75 °. If the nozzle direction is not arranged at right angles to the filter grid, compressed air can be applied to a large area with a few nozzles. Due to the angle of the nozzles, a larger distance to the filter grid can be realized, wherein the generated conical air jet then detects a much larger area than in a rectangular array.
- At least one of the nozzles can be designed such that it generates a nozzle jet rotating about a main emission direction.
- a rotating element is arranged, which generates the rotating nozzle jet.
- the rotation can be generated by the connected compressed air or a separate auxiliary drive.
- Such a rotation of the nozzles or the jetting can further improve the cleaning process, since fewer nozzles can impinge on a larger area with a high impulse and thus more easily loosen the dirt from the filter grid.
- the compressed air supply of the pipe device can be controlled by means of a pulse valve, such that the backwashing is carried out with the aid of pulse-like backwash surges.
- a pulse valve such that the backwashing is carried out with the aid of pulse-like backwash surges.

- the air filter may be formed as a grid.
- the grid may be formed as a fine-meshed stainless steel mesh.
- the advantage of using a grid is that it can be well cleaned of fibers by high pressure air due to its smooth surface properties.
- a metal grid has the advantage of a long service life and is also dimensionally stable even at high air pressure.
- the filter grid may be inclined, with the result that the dirt particles may already fall off the grid by gravity. At least we support cleaning by doing so.
- the air filter may be formed as a radiator. In this embodiment, another air filter can be used to increase the filter effect. Alternatively, it is possible to dispense with a further air filter, so that fewer components are required for the device presented here, whereby a maintenance effort can advantageously be reduced.
- the present invention further provides a radiator device for a vehicle, comprising: a device for cleaning according to one of the preceding claims; the air filter for filtering the cooling air; and a cooler for cooling the cooling air, wherein the device, the air cleaner and the radiator are disposed adjacent to each other in a flow direction of the cooling air so that the air filter and / or the radiator can be cleaned by the apparatus.
- the cooler device can be used for example for cooling a drive of a railcar of a rail vehicle.
- the cooling air may be outside air that may flow into the radiator device through the air filter when the rail vehicle is being moved.
- the radiator can be designed so that it can be flowed through by the cooling air.
- the device may be arranged in the direction of flow of the cooling air at the second position behind the air filter or alternatively at the second position behind the radiator or alternatively at the third position behind the air filter and the radiator.
- the cooler device may include a fan for conveying the cooling air in the flow direction.
- the fan may be a fan which may be arranged in the flow direction of the cooling air at the last position in the cooler device.
- the use of the fan in the cooler device has the advantage that the cooling air can reach the cooler faster and in larger quantities.
- the device may be arranged upstream of the radiator in the flow direction of the cooling air. Such an arrangement of the device offers the advantage that the cooling air impinging on the radiator is already filtered.
- An alternative arrangement of the device in the flow direction of the cooling air to the radiator can make a use of the air filter superfluous, if the radiator is used simultaneously as an air filter. In this case, the cooler can be cleaned by the device.
- the air filter can be cleaned by the compressed air of the device flowing through the radiator.
- the more suitable of the two proposed constructions of the cooler device can be used.
- the cooler device presented here may be part of an underfloor cooling system of a rail vehicle.
- Such underfloor cooling systems are often used for cooling of Treibzugsantrieben. Due to the ground proximity of such systems and the associated high degree of contamination of the filter component, the approach presented here of efficient and economical filter cleaning is of particular importance.
- the present invention further provides a method for cleaning an air filter of a vehicle by means of a device for cleaning the air filter, comprising a backwashing device and / or a vibration device, the method comprising the following steps: detecting a movement state of the vehicle and / or an operating state of a Fan for generating and / or supporting a cooling air flow; Actuating the backwashing device and / or the vibration device depending on the state of movement and / or operating state in order to clean the air filter by means of compressed air and / or by means of vibration.
- the state of motion may relate to an acceleration or a speed of the vehicle.
- the device can be acted upon in each case at the end of an acceleration process with the compressed air and / or vibration.
- the end of the acceleration process can be provided for example by means of a corresponding signal to a control device of the device for cleaning.
- the control unit can control, for example, a vibration generator and / or a valve of the connection in order to supply compressed air from a compressed air line of the vehicle to the pipe device.
- the cleaning can be triggered when the vehicle is outside a locality.
- the operating state of the respective fan can be taken into account.
- the respective fan generates or amplifies the cooling air flow, which generates the accumulation of impurities on the air filter. If there is little or no cooling demand, the fan can be switched off or generate only a comparatively weak flow of cooling air. Consequently, the cleaning effect can be improved if the cleaning takes place in operating phases in which the fan is not or only with reduced power in operation.
- a corresponding controller can monitor the power consumption of the fan or a signal corellated in order to carry out the cleaning of the air filter preferably when the power of the fan is below a predetermined limit value.
