Definitions

  • the invention relates to a vehicle and a method for Operating the vehicle according to the preamble of independent claims.
  • the invention is based on the object at a Vehicle according to the preamble of the first claim Measures to be taken by which an energy-optimized, functional operation of the air compressor allows becomes.
  • the Air compressor always with the main engine running through the drive power supplied by the main drive motor be driven so that no additional electrical or mechanical conversion losses occur as in the case of Drive through a separate electric motor inevitable are.
  • a can power split transmission are used over the the air compressor with the main drive motor in Drive connection is.
  • This gearbox has one in addition Output drive for the air compressor and a first Input drive for the required coupling with the Main engine still has a second input drive, the if necessary, in drive connection with the electric motor for the air compressor stands.
  • the entire electrical system of the vehicle can supply with electrical energy, then it is particularly advantageous, by means of the air compressor and the for the operation of the individual cells of the fuel cell and / or necessary for any reformer to provide oxygenated process air.
  • the Fuel cell can also in one Fuel cell system can be arranged, which also with a conventional gas generating system may be equipped, in which a reformer is provided, in which a hydrogen-rich reformate obtained from a fuel becomes.
  • the fuel cell delivers the same electric current for driving the electric motor, the instead of the main drive motor drives the air compressor, so that unlike a battery as a power source Continuous operation of the electrical system and the air compressor is possible.
  • the vehicle 1 shows a vehicle not shown in detail, in particular a passenger or commercial vehicle forfractionoder Rail operation, which is a main drive motor 1 having, as an internal combustion engine or as an electric Traction motor is formed.
  • the main drive motor 1 can via a drive train with activated transmission 2 and optionally coupling with a pair of vehicle wheels 3 in Drive connection are brought.
  • the transmission 2 is as a power-split transmission 2 is formed over a first input drive 4 with the main drive motor. 1 and via a second input drive 5 with a additional drive motor, in particular with a Electric motor 6 in drive connection seht.
  • the power-split transmission 2 can also with a first Output 7 be provided with the vehicle wheels. 3 is coupled.
  • the power-split Transmission 2 to a second output drive 8, via the one Air compressor 9 is driven.
  • the air compressor 9 sucks via an intake 10 atmospheric air with Oxygen content from the environment and gives it compressed via a compressed air line 11 as process air for Supply of oxygen for the power generation process on a serving as a power source fuel cell 12 from. moreover can the compressed air through branch lines 11.1 and 11.2 for the compressed air supply of pneumatic Braking devices 13 and air spring devices or
  • Level control devices 14 serve, by means of which the Vehicle wheels 3 braked or vehicle suspension system can be operated.
  • the fuel cell 12 generates demand-controlled electric power supplied to an electrical control system 15 is supplied.
  • the control system 15 is used to control the Electric motor 6, the main drive motor 1 and the power split transmission 2 and can also more electrical control devices or consumers, such as Lights 16, seat heaters 17, defroster systems 18, air conditioning and Ventilation 19 and other electrical Consumers and also the fuel cell 12 and a in particular the startup of the fuel cell 12 serving Power, control and charge the battery 20.
  • the control of the air compressor 9 takes place in this structure in such a way that is driven in the usual driving operation of the vehicle with the main drive motor 1 of the air compressor 9 via the power-split transmission 2 and the necessary air consumers (fuel cell 12, braking device 13, level control device 14) with the required Air volume feeds.
  • the main drive motor 1 is switched off or runs the same with a lying below a predetermined value speed, which no longer ensures a provision of the required amount of air, the electric motor 6 is put into operation.
  • the electric motor 6 then drives the air compressor 9 directly via the power-split transmission 2, the other drive train being decoupled from the electric motor 6.
  • the electric motor 6 can also be used for the additional or possibly decoupled main drive motor 1 for the sole drive of the vehicle wheels 3.
  • the provision of electrical energy for the additional drive motor 6 takes place from the fuel cell 12, which preferably feeds the entire electrical system of the vehicle.
  • the air compressor 9 can then be driven by the electric motor 6 if necessary. In this case, the drive can be done by the drive motor 1 or the electric motor 6 either in traction mode.
  • the air compressor preferably supplies the compressed air for the Brake system, the air suspension and / or the Level control of the vehicle.
  • the drive of the air compressor 9 through the Drive motor 1 and at low speed of the Drive motor 1 or at standstill by the electric motor 6th
  • an additional, preferably electric motor driven air compressor 9.1 provided his. This is shown in Fig. 2 by the dashed lines Air compressor 9.1 shown schematically. Same Components as in Fig. 1 are denoted by the same reference numerals characterized.
  • the additional air compressor 9.1 can ensured a dual-circuit of compressed air generation become.
  • the other air compressor 9.1 or 9 with the compressed air system Supply compressed air.
  • the air compressor 9 and the additional electric motor driven air compressor 9.1 can occasionally with respect to the compressed air line 11 in series be switched. Preferably then in the Connecting line between the two air compressors Provided check valve.
  • the drive can but also by a suitable drive connection, such as a preferably uncoupled belt drive or the like, take place via the electric motor 6.
  • This additional electric motor-driven air compressor 9.1 can preferably switched on independently of air compressor 9 become. This is a two-circuit compressed air generation allows. It is advantageous that this additional Air compressor 9.1 can be switched on demand-oriented, for example, with an additional need for compressed air for braking or when operating compressed air supplied Lifting mechanisms of the vehicle.
  • this additional Air compressor 9.1 e.g. depending on the on-board voltage and / or the driver request and / or the pressure level of Compressed air system to be switched on.
  • the design of the driven by the drive motor, preferably demand and performance optimized air compressor 9 is suitably carried out according to the Normal service operations expected compressed air consumption and can therefore be e.g. about the main parts of a vehicle energy-optimized.
  • the additional electric motor driven air compressor 9.1 activated and so a sufficient compressed air supply ensure, for example, during a descent with high Compressed air consumption during braking.
  • the additional electric motor driven air compressor 9.1 can be readily available at startup by: this about the ignition key position "ignition on” is already switched on at high constant speed.
  • the additional electric motor driven air compressor 9.1 already Driving on a timer for filling the Driving pressure levels are turned on. This can be for Noise minimization at low speed of the air compressor respectively.
  • the fast start readiness can in this Way also be achieved via the air compressor 9, though this is driven by an electric motor.
  • the Compressed air system of the vehicle is then already at startup of the main drive motor 1 filled and ready for operation.
