Definitions

  • the invention relates to a rail vehicle with a vehicle frame supported on rail bogies and a hydraulic drive system driven by a motor, which comprises a hydrodynamic drive assigned to a first rail bogie and a hydrostatic drive assigned to a second rail bogie, to which a traction pump connected to a drive motor is assigned .
  • the invention also relates to a method for operating this rail vehicle.
  • Rail vehicles and track construction machines with hydrodynamic and / or hydrostatic drive are already well known.
  • the power required to operate such vehicles is the product of traction and speed.
  • the tractive force depends on the mass of the rail vehicle, the number of axles (total or driven) and the coefficient of friction between the rail and the wheel.
  • the invention has for its object to provide a rail vehicle and a method for its operation, with which an optimal power distribution of the drives can be achieved with changing coefficients of friction between wheel / rail.
  • this object is achieved in that the motor is designed for a higher power output than is required for the operation of the hydrodynamic drive, and in that a pump distribution gear is interposed between the motor and the hydrodynamic drive, via which the drive pump of the hydrostatic drive can be activated .
  • This training ensures a very good transmission of the drive power to the rail.
  • a constant power transmission is achieved especially under often changing external, weather and season-dependent conditions and the resulting changes in the coefficient of friction.
  • Rain, snow and ice, but also dirt from mud or autumn leaves change the coefficient of friction extremely unfavorably.
  • At least one further hydraulic pump for operating at least one further hydraulic drive for a working unit is assigned to the pump distribution gear.
  • various work units such as a crane, lifting platform, plow or even a snow blower
  • a hydraulic drive that is optimally designed for operation for the respective unit.
  • the drive consisting of pump and motor can be dimensioned according to the special requirements, so that an economical and performance-adjusted operation is guaranteed.
  • the object of the invention is also achieved by the use of a method in a rail vehicle according to the invention, in that Dependency of a friction value ⁇ between rail and wheel - the hydrostatic drive is switched on or off.
  • a particularly advantageous embodiment of the method is achieved by the following steps: a) determining a decreasing coefficient of friction ⁇ when operating with a hydrodynamic drive, b) switching on the hydrostatic drive by engaging the drive pump and the second drive motor, c) increasing the power of the motor, d) Operation of the rail vehicle with hydrodynamic and hydrostatic drive, e) reduction of engine power when a critical speed is exceeded, f) switching off the hydrostatic drive by disengaging the drive pump and the drive motor and g) operation of the rail vehicle with hydrodynamic drive.
  • Such method steps enable reliable and safe operation of the rail vehicle, which can be carried out almost independently of the difficult conditions already mentioned. Simultaneously increasing the engine power and dividing this power between the hydrodynamic and hydrostatic drive enables the rail vehicle to be operated largely unaffected by the unfavorable coefficient of friction, while the required adhesion between the rail and the wheel is always maintained. In the higher speed range, an increased engine power or a drive on several axles is no longer necessary, which is why the rail vehicle can be driven again by the hydrodynamic drive to save energy.
  • FIG. 1 A rail vehicle 1 designed as a track construction machine is shown. This essentially consists of a vehicle frame 4 supported on a first and a second rail undercarriage 2, 3.
  • the rail vehicle 1 has a hydraulic drive system 6 which is driven by a motor 5 which is preferably designed as an internal combustion engine.
  • This comprises a hydrodynamic drive 7 assigned to the first rail running gear 2 and a hydrostatic drive 8 assigned to the second rail running gear 3.
  • the latter is - as in FIG Fig. 2 can be seen - assigned a drive pump 10 connected to a drive motor 9.
  • the motor 5 is designed for a higher power output than is required for the operation of the hydrodynamic drive 7.
  • a pump distribution gear 11 is interposed between the motor 5 and the hydrodynamic drive 7.
  • the drive pump 10 of the hydrostatic drive 8 can be activated via this.
  • At least one further hydraulic pump 12 for operating at least one further hydraulic drive 13 for a working unit 14 is assigned to the pump distribution gear 11.
  • work units 14 would be crane 15, lifting platform 16 or snow blower 17.
  • the number of further hydraulic pumps 12 can vary in that either each work unit 14 is assigned its own hydraulic pump 12, or that a hydraulic pump 12 alternately drives one of the work units 14 .
  • the operation of the rail vehicle 1 is briefly described below. The operation takes place as a function of a coefficient of friction ⁇ between a rail 18 and a wheel 19, the hydrostatic drive 8 being switched on or off.
  • the rail vehicle 1 is mainly moved with the hydrodynamic drive 7.
  • the falling coefficient of friction ⁇ is determined with the aid of a measuring device 20.
  • the hydrostatic drive 8 is then switched on manually or automatically by engaging the drive pump 10 and the drive motor 9 Power of the motor 5, the rail vehicle 1 is now operated with hydrodynamic and hydrostatic drive 7, 8. If a critical speed v K is exceeded, the power of the motor 5 is reduced again and the hydrostatic drive 8 is switched off. This is done by disengaging the drive pump 10 and the drive motor 9.
  • the rail vehicle 1 is then driven again only by the hydrodynamic drive 7.
