Definitions

  • the present invention relates to road pavers with a chassis that can be raised at least in a rear region of the road paver with respect to the chassis.
  • Known road pavers include, with respect to a paving direction of travel, a material bunker for receiving paving material at the front of the paving machine.
  • the paving material is conveyed from the material bunker to a rear area of the road paver via a suitable longitudinal conveyor device.
  • the paving material is distributed transversely to the paving direction by means of a distribution auger and is thus evenly presented to a screed that is pulled behind by the paver for compacting the paving material.
  • the road paver can be adapted to paving different layer thicknesses.
  • the distribution auger can be raised in relation to the chassis in order to build in thicker layers.
  • a disadvantage of such a system is that for the installation of very thick layers, the position of the distribution screw relative to the chassis is significantly changed upwards. This can lead to the situation that the distribution screw at least partially blocks a material outlet of the longitudinal conveyor device. As a result, the throughput of paving material to the screed is reduced, which is particularly disadvantageous in the case of large layer thicknesses, since an increased amount of paving material is required for this.
  • a road paver whose rear area can be raised for paving thick layers. This is achieved by means of a height-adjustable vertical guide between a crawler track and a chassis of the road paver in the rear area of the road paver. In a front area, the chassis is rotatably mounted on the crawler track.
  • the disadvantage of this system is the high Loads on the hydraulic actuating cylinders, which essentially completely bear the weight of the chassis. Correspondingly high forces are required to adjust the height. In addition, the stability of the road paver suffers.
  • a connection to the chassis of the road finisher is provided on an outer surface of the disk, which connection is rotatable about a secondary axis lying transversely to the paving direction of travel.
  • the disk can be rotated in its mounting on the chassis by means of a hydraulic cylinder.
  • the hydraulic cylinder When the disk rotates, due to the eccentricity of the connection between the disk and the running gear, the mutual height relationship between the chassis and the running gear changes in a rear region of the road finisher.
  • the hydraulic cylinder still has to apply high forces to rotate the disk when the chassis is raised. Even when the chassis is held in a certain height position, high loads act on the hydraulic cylinder.
  • the paver comprises a running gear with two traction tracks and a chassis. It also comprises a material bunker attached to the chassis at the front of the road paver with respect to the paving direction of travel and a screed provided at the rear of the road paver with respect to the paving direction of travel, which is attached to the chassis by drawbars. In addition, it comprises a lifting device which is designed to raise the chassis relative to the running gear at least in a rear area of the road finisher.
  • the road paver according to the invention is characterized in that a material deflector which can be pivoted relative to the chassis is arranged between the two traction tracks, the road paver further comprising a coupling mechanism which is configured to pivot the material deflector relative to the chassis when the lifting device does Raises the chassis in relation to the running gear.
  • the running gear can be designed as a chain running gear or a wheeled running gear and can support the chassis.
  • the material deflector when not in use, for example when the chassis is completely lowered, the material deflector can be carried along in a folded position on the paver finisher. As a result, both dismantling after lowering and assembly during or before lifting can be superfluous.
  • an actuator unit is provided which is configured to move the material deflector relative to the chassis, in particular to pivot it.
  • a sensor unit is also conceivable which is configured to detect a distance between the chassis and a base and / or a lifting movement between the chassis and the chassis and / or the distance between a lower edge of the material deflector and the base. This enables the swiveling process of the material deflector to be monitored, controlled or regulated.
  • the actuator unit is configured to pivot the material deflector based on signals generated by the sensor unit.
  • the (pivoting) position of the material deflector can be adapted to one or more of the above-mentioned parameters that can be detected by the sensor unit. It is conceivable, for example, that the distance between the lower edge of the material deflector and the ground is continuously recorded and, by regulating the (pivoting) position of the material deflector, can be kept constant even when the chassis is raised. It is particularly favorable if a distance between the ground and a lower edge of the material deflector is always the same size or greater than the minimum ground clearance of the road paver.
  • the actuator unit can comprise an electrical, hydraulic, electrohydraulic or pneumatic actuator.
  • the sensor unit can have a laser sensor, a radar sensor or an ultrasonic sensor.

  • the bearing surface on the chassis side can be a bearing surface that is part of the chassis or is at least firmly connected to the chassis.
  • the bearing surface on the chassis side can be a bearing surface that is part of the chassis or is at least firmly connected to the chassis.

  • the pivot point on the chassis side can be a pivot point that is part of the chassis or is at least firmly connected to the chassis.
  • the point of articulation on the rocker side can be a point of articulation that is part of the rocker or is at least firmly connected to the rocker.
  • the adjustable-length adjusting element can each be connected in an articulated manner to the articulation point on the chassis and the articulation point on the rocker side.
  • a first end of the adjustable-length adjusting element is articulated to the articulation point on the chassis side and a second end of the adjustable-length adjusting element is articulated to the rocker-side articulation point.

  • disadvantages such as those already described above with reference to the installation material coming under the chassis can be avoided.
  • the chassis protection is covered by the chassis towards a rear side of the road finisher in a position of the chassis that is maximally lowered with respect to the chassis and can be exposed by lifting the chassis.
  • Such a configuration can have the advantage that no additional mechanism is required to bring the landing gear protection into a desired position. Rather, the landing gear protection can be provided in a suitable position and only used when the chassis is raised.
  • the actuator unit and / or the coupling mechanism can have an elastic element. Such an elastic element can prevent damage to the actuator unit or the coupling mechanism, for example if the material deflector hits or is blocked by objects when pivoting or driving the road finisher.
  • the elastic element can be prestressed.
  • a deflection can be understood to mean a change in length or, in general, a change in dimensions, a torsion or a reversible deformation.
  • the distance between two axes or between an axis and a bearing surface can be defined as the respective minimum distance.
  • a distance between the chassis rotation axis and the chassis rotation axis can be greater than a distance between the chassis rotation axis and the chassis-side bearing surface. This can mean that the chassis axis of rotation is outside of the mounting of the rocker on the chassis.

  • the adjustable-length adjusting element is preferably configured to change the position of the rocker in relation to the running gear or the chassis by changing its length.

  • the ratio described can in particular lie above one of the stated limit values over the entire setting range of the chassis height. However, it can also be sufficient if this is the case in a maximally lowered or maximally raised state of the chassis or in at least one raised state of the chassis in between.
  • the adjustable-length adjusting element preferably extends at least substantially along a horizontal direction.
  • the weight of the chassis acting at least essentially along a vertical direction is at least partially absorbed by the rocker or the chassis-side and the chassis-side mounting surface and does not have to be completely supported by the adjustable-length adjusting element. This contributes to the stability of the entire arrangement.
  • the fact that the adjustable-length adjusting element extends at least substantially along a horizontal direction can mean that a horizontal component of the direction of extension of the adjustable-length adjusting element is greater than a vertical component of the direction of extension of the adjustable-length adjusting element, and / or that an angle of inclination between the adjustable-length adjusting element and a horizontal plane does not exceed 10 °, 15 °, 25 ° or 45 °.
  • the articulation point on the chassis side is preferably located in front of or behind the chassis axis of rotation and / or the chassis axis of rotation at least in some operating positions with respect to the installation direction of travel. A good power transmission can thus be achieved due to a leverage effect.
  • a lower stop can be provided on the chassis, which is configured to secure the chassis against further lowering by engaging the rocker in a maximally lowered state of the chassis. In this way, the adjustable-length adjusting element is relieved when the chassis is lowered to the maximum. In addition, the maximum is lowered State of the chassis firmly defined by the stop.

  • the locking element can be extended horizontally, in particular perpendicular to the direction of installation.

  • the sensor unit 89 can be connected to the control unit 87 in order to transmit measured or recorded values to the control unit 87.
  • the coupling mechanism 75 can furthermore have an actuator unit 91.
  • This can be connected to the control unit 87 in order to receive control signals.
  • the actuator unit 91 can also be connected to this in order to receive control signals.
  • the actuator unit 91 can have an actuator 93. This can be configured to to pivot the material deflector 71.
  • the actuator 93 can be any suitable actuator known to a person skilled in the art.
  • electrical, hydraulic, electrohydraulic or pneumatic actuators are conceivable, for example an electric or servo motor, or a hydraulic cylinder. Accordingly, it can be in the control unit 87 z. B. to be an electrical, hydraulic, electrohydraulic or pneumatic control unit.
  • the sensor unit 89 detects the distance g between the lower edge 73 of the material deflector 71 and the substrate 85 and transmits this to the control unit 87.
  • the control unit 87 can then be configured in such a way that, based on the received distance, it transmits control signals to the actuator unit 91, which cause the actuator unit 91 to control the actuator 93 in such a way that the distance g between the lower edge 73 and the ground 85 remains constant .
  • the sensor unit 89 can detect the lifting movement i and transmit this to the control unit 87. Based on the lifting movement i, this can determine a target position of the material deflector 71 which is assigned to the detected lifting movement i.
  • An assignment of a lifting movement i to a position of the material deflector 71 can be established by means of mathematical formulas or tables. It is conceivable that the control unit 87 transmits the target position to the actuator unit 91 and that the latter independently controls or regulates the actuator 93 in such a way that the material deflector 71 assumes the received target position. However, it is also conceivable that the control unit 87 itself comprises a controller and only transmits control signals to the actuator unit 91.
  • FIG 9A is a side view of a chassis 5 of a road finisher 1 according to a further embodiment.
  • a landing gear protection 95 is provided. This can, for example, as shown in the exemplary embodiment, be attached to the caterpillar carrier 37.
  • the chassis 3 In the configuration shown, the chassis 3 is completely lowered with respect to the running gear 5. In this configuration, the landing gear protection 95 is covered by the chassis 3 towards the rear as seen in the direction of travel. In this configuration, the chassis 3 prevents installation material from reaching the area of the chassis 5.
  • the chassis 3 is raised relative to the chassis 5.
  • the landing gear protection 95 can be exposed.
  • the landing gear protection 95 can prevent installation material from getting into the area of the landing gear 5. It can also be seen that without the landing gear protection 95 between the lower The edge of the chassis 3 and the ground would be significantly more space that would allow the installation material to get into the area of the chassis.
