Definitions

  • the present invention relates to a Snow grooming vehicle with swivel mounted Milling machine according to the preamble of claim 1.
  • the object of the present invention is in it, both a defined number of meshes the milling shaft towards the path maintain the cutting depth of the milling teeth in such a way that it should be possible the energy input into the snow if possible to keep low.
  • Figure 1 is generally with the reference number 1 the outline of a piste grooming vehicle according to of the present invention.
  • the snow grooming vehicle includes a diesel engine 2, which in a known manner with a Drive 3 and a drive 4 connected is, each operate a drive wheel 5 and 6.
  • the diesel engine 2 also drives one Control pump 9, which is a hydrostatic Circulation 10 circulates.
  • the hydrostatic circuit 10 has one Pressure line 11 with a hydraulic motor 12 is connected, which in turn has a Return line 13 fed back to the control pump 9 is.
  • the hydraulic motor 12 drives a milling machine 14, 15.
  • the pressure of the pressure line 11 is monitored by a sensor of a known type, not shown, which is connected to a control unit 17 via a line 8.
  • Sensors of a known and therefore not shown type detect the speed n F of the milling cutter 14, 15 and deliver the corresponding quantities via the lines 21 of the control unit 17.
  • the control unit 17 is also connected via lines 19 and 20 sensors, also of a known type, which detect the speeds n a1 , n a2 of the drive wheels 5 and 6. In a similar way, a sensor that detects the speed of the diesel engine is connected to the control unit 17 via a line 18.
  • a working cylinder 16 provided in a known manner and Move the swivel-mounted milling cutter around you Angle ⁇ regulates its inclination ( Figure 2).
  • On the path and / or pressure of the working cylinder 16 sensing sensor is connected via a line 7 the control unit 17 connected.
  • the control unit 17 is via a line 22 with the working cylinder 16 and via a line 23 with the regulating pump 9 for regulating the same as detailed below fed back.
  • the necessary to the respective snow conditions customized setting of work pro The operator runs a route using a Ratio of milling speed to driving speed and a torque specification.
  • the automatic adjustment is implemented by using the control unit 17, which is supplied with the following measured values from the corresponding sensors specified above, Speed of the diesel engine n D Speeds of the drive wheels n a1 , n a2 Pressure in the hydrostatic milling drive p F
  • n F is dependent on the diesel speed and the transmission ratio (n D / n F ), which in turn is influenced solely by the pump current I F.
  • n F f (n a (1,2) , n D , I F )
  • Engaging teeth / distance f (n a (1,2) , n D . I F )
  • the setpoint is specified for both variables with actuators, which, for example, output an analog signal as a value (eg potentiometer).
  • actuators which, for example, output an analog signal as a value (eg potentiometer).
  • N Fmax results from the limits of the drive, since at a given diesel speed and max. Gear ratio the limit speed is reached on the milling shaft.
  • V / Vu is corresponding a freely selectable setting, which creates different engagement curves of the teeth result (see Figures 5 and 6).
