Definitions

  • the invention relates to a paver according to the preamble of claim 1.
  • the operator is in manual roof profile adjustments immediately above the adjustment elements for the roof profile adjustment, so that the counter can be made from there. - But when the roof profile adjustment electromechanically or electrohydraulically from a distant one, not near the adjusting elements, but for example, operators on the side of the road are made, countering or clearing the adjustment elements presents a problem represents.
  • the object of the invention is a paver according to the Preamble of claim 1 to create, in which only after the completion of a the adjustment elements for the roof profile adjustment be countered and thus eliminates play in the adjusting elements becomes.
  • a brake designed as a spring brake is used, via which the two plank halves are coupled together and which is released due to the actuation of the adjusting device and regains its full braking effect by ending the adjustment process, for any game in spindles or game due to Eliminate leakage in hydraulic cylinders.
  • the latter happens independently on the size of the adjustment process and automatically, with the Adjust the full force applied is available.
  • the screed of a paver shown in Fig. 1a, 1b is used for the floating installation of corresponding layers Road and is over (not shown) draw arms on a chassis articulated, the front of a bucket to hold the installation material from where the paving material by means of a conveyor into the Area of a screw conveyor is conveyed, which is in the direction of installation in front of the screed.
  • the screed comprises two screed halves 1a, 1b, which if necessary are extendable and / or attachable.
  • the two plank halves 1a, 1b are about a pin 2, the longitudinal axis of which extends in the direction of installation extends, pivotable against each other, for example around a roof profile, as indicated by dash-dotted lines in Fig. 1a to form.
  • On the upper side is on each plank half 1a, 1b extending in the direction of installation Bridge 3 attached.
  • the two plank halves 1a, 1b are made from one rectilinearly aligned position (shown in solid lines in FIG. 1a) in a roof profile position (dash-dotted in Fig. 1a) or from this in the straight-line position corresponding to the intended one Road profile pivoted during the installation of a corresponding layer.
  • the spring brake 9 comprises a cylinder 10 in which a piston 11 is arranged, which can be pressurized via a pressure fluid inlet 12 is.
  • the piston 11 is in its starting position by a plate spring 13 pre-tensioned spring assembly and has a shaft 14, which extends out of the cylinder 10 and ends with a thread is provided.
  • the spring brake 9 has friction surfaces 15 which of sheets 16 arranged in pairs and interlocking with elongated holes 17 are formed, each on opposite bolts 18, added are rotatably supported by the bearing eyelets 8. Through the elongated holes 17 extends the shaft 14 of the piston 11, which on the cylinder 10 opposite side a washer 19 and two countered Nuts 20 carries.
  • a pump 21 generates a supply 22 is connected from hydraulic fluid, correspondingly pressed hydraulic fluid, that via a throttle 23 on an electromagnetic control valve 24 pending. Appropriate control of the control valve 24 the double-acting hydraulic cylinders 7 for mutual adjustment of the screed halves 1a, 1b.
  • the cylinder 10 is connected via a line 25 to the after Pump 21 applied pressure of the hydraulic fluid. If that Control valve 24 is actuated to adjust the hydraulic cylinders 7 results in a line from the pump 21 to the control valve 24 Pressure increase via line 25 to the piston 11 of the cylinder 10 acts so that the piston 11 against the force of the plate springs 13th is moved and accordingly the friction surfaces 15 are vented from each other.
  • Pressure increase via line 25 to the piston 11 of the cylinder 10 acts so that the piston 11 against the force of the plate springs 13th is moved and accordingly the friction surfaces 15 are vented from each other.
  • the loading of the hydraulic cylinder 7 builds up the pressure increase again and the piston 11 is driven by the force of the Disc springs 13 pushed back into its starting position in which the Friction surfaces 15 are engaged again and the spring brake 9 mechanically their full braking effect and any Game eliminated through leakage.
  • sprockets can be driven electrohydraulically or electromechanically.
  • the spring brake 9 in the illustrated embodiment via an electrically operated valve in a corresponding hydraulic circuit hydraulically actuated when the spindles are driven for ventilation.
  • the spring-spoke brake 9 can also be released electromagnetically his.
