Definitions

  • the present invention relates to road pavers with a liftable at least in a rear region of the paver chassis relative to the chassis.
  • Known road pavers include with respect to a Einbaufahrtraum the front of the paver a Gutbunker for receiving built-in. From the Gutbunker the paving material is conveyed during installation via a suitable longitudinal conveyor in a rear area of the paver. There, the built-in material is distributed by means of a distribution auger transversely to the installation direction and so evenly submitted to a trailed by the paver screed for compacting the paving.
  • the auger height adjustable By adjusting the height of the auger with respect to the chassis, the paver can be adapted for the installation of different layer thicknesses. For example, the auger can be raised relative to the chassis to accommodate greater layer thicknesses.
  • 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 changed significantly upwards. This may lead to the situation that the distributor screw at least partially blocks a material outlet of the longitudinal conveyor. As a result, the throughput of built-in material for screed is reduced, which is particularly disadvantageous for large layer thicknesses, since an increased amount of paving material is required for this.
  • the disc can be rotated in its storage on the chassis by means of a hydraulic cylinder.
  • a hydraulic cylinder As the disk rotates, due to the eccentricity of the connection between the disk and the chassis, the mutual height relationship between the chassis and the chassis changes in a rear area of the paver.
  • the weight of the chassis does not have to be borne entirely by the hydraulic cylinder, it still has to apply high forces to rotate the disk when lifting the chassis. Even when holding the chassis in a certain height position, high loads act on the hydraulic cylinder.
  • Raising the chassis increases the distance between the chassis and the ground, creating a space where the product can penetrate. This can increase the time it takes to cool down the build-in material under the chassis before it is compacted by the screed. In addition, segregations may occur. Both can lead to a deterioration in the quality of the laid asphalt surface.
  • the paver according to the invention comprises a chassis with two tracks of traction and a chassis. It further comprises a respect to a direction of incorporation on the front of the paver mounted on the chassis Gutbunker for receiving items and with respect to the direction Aufaufahrtraum behind the paver provided screed for compacting built-in, which is attached by Switzerlandholme to the chassis. In addition, it comprises a lifting device, which is designed to lift the chassis relative to the chassis at least in a rear region of the paver.
  • the paver according to the invention is characterized in that between the two traction tracks a movable, in particular pivotable Materialabweiser is arranged relative to the chassis.
  • a displaceable material deflector is also conceivable.
  • Such can be designed as a sliding plate.
  • a movable plate can, for. B. be slidably received in a recess on or in the chassis and pushed out of this to extend the Materialabweiser.
  • traction tracks can be considered areas that extend substantially in the direction of travel and in which traction elements of the chassis of the paver are in engagement with the ground to ensure the propulsion and directional fidelity of the paver.
  • the chassis can be designed as a chain or wheel chassis and carry the chassis. Due to the arrangement of the material deflector between the traction tracks, penetration of built-in material into the space between the traction tracks or between the chassis and the ground can be prevented. Due to the movable design of the material deflector, on the one hand, it can be ensured that its arrangement can be adapted to different lifting heights of the chassis. On the other hand, the Materialabweiser when not in use, for example, when completely lowered chassis, in a folded position continue to be carried on the paver. As a result, disassembly after lowering as well as mounting during or before lifting can become superfluous.
  • an actuator unit is provided which is configured to move the material deflector relative to the chassis, in particular to pivot.
  • a sensor unit which is configured to detect a distance of the chassis from a ground and / or an appendage between the chassis and the chassis and / or the distance of a lower edge of the Materialabweisers to the ground. This allows monitoring, control or regulation of the lifting process and / or the pivoting process of the material deflector.
  • the actuator unit is configured to move the material deflector based on signals generated by the sensor unit, in particular to pivot it.
  • the (swivel) position of the material deflector can be adapted to one or more of the above-mentioned, detectable by the sensor unit parameters. It is conceivable, for example, that the distance between the lower edge of the material deflector and the substrate is detected continuously and can be kept constant by regulating the (pivoting) position of the material deflector even when the chassis is raised.
  • the actuator unit may comprise an electric, hydraulic, electro-hydraulic or pneumatic actuator.
  • the sensor unit may have a laser sensor, a radar sensor or an ultrasonic sensor.
  • the lifting device comprises a rocker which is mounted rotatably about a chassis rotation axis on a chassis-side bearing surface and is rotatably mounted about a chassis rotation axis on a chassis side bearing surface.
  • the chassis-side bearing surface may be a bearing surface that is part of the chassis or at least firmly connected to the chassis.
  • the chassis-side bearing surface can be a bearing surface that is part of the chassis or at least firmly connected to the chassis.
  • the chassis rotation axis and the chassis rotation axis are parallel to each other and in particular each extend in a horizontal plane and perpendicular to the installation direction, ie in a transverse direction of the paver.
  • the chassis rotation axis and the chassis rotation axis is not identical.
  • the chassis rotation axis and the chassis rotation axis are offset parallel to each other.
  • the lifting device also comprises a variable-length adjusting element which connects a chassis-side linkage point to a rocker-side linkage point and is configured to change a distance between the chassis-side linkage point and the rocker-side linkage point by changing its length and thus face the chassis either raise or lower the suspension.
  • the chassis-side pivot point can be a pivot point that is part of the chassis or at least firmly connected to the chassis.
  • the rocker-side articulation point can be an articulation point, which is part of the rocker or at least firmly connected to the rocker.
  • variable-length adjusting element can each be pivotally connected to the chassis-side pivot point and the rocker-side pivot point.
  • a first end of the variable-length adjustment member is pivotally connected to the chassis-side pivot point and a second end of the variable-length adjustment member hingedly connected to the rocker-side pivot point.
  • the variable-length adjusting element extends on one side or on both sides beyond the respective articulation point.
  • the paver may include a coupling mechanism configured to pivot the material deflector relative to the chassis when the lift raises the chassis relative to the chassis.
  • a coupling mechanism configured to pivot the material deflector relative to the chassis when the lift raises the chassis relative to the chassis.
  • the coupling mechanism may comprise a lever which is rotatably mounted on the chassis.
  • the coupling mechanism comprises a control or control unit which is connected to the sensor unit and the actuator unit, wherein the control or control unit actuates the actuator unit in response to signals received from the sensor unit.
  • a chassis protection is provided, which is arranged in the installation direction behind one of the traction tracks. As a result, it can be prevented that built-in material reaches traction elements of the paver and there, for example, their Traction properties can adversely affect. In addition, disadvantages, such as those described above with respect to under the chassis reaching property can be avoided.
  • the undercarriage protection is concealed in a position of the chassis which is lowered at the maximum relative to the chassis by the latter to a rear side of the road paver and can be exposed by lifting the chassis.
  • Such a configuration may have the advantage that no additional mechanism is needed to bring the undercarriage protection into a desired position. Rather, the undercarriage protection can be provided at a suitable position and used only when the chassis is raised.
  • the actuator unit and / or the coupling mechanism may comprise an elastic element.
  • an elastic element can avoid damage to the actuator unit or the coupling mechanism, for example when the material deflector encounters or is blocked by objects when moving and / or pivoting or when driving the paver.
  • the elastic element may be biased.
  • the elastic element is configured to be deflected when the movement and / or pivoting of the material deflector is blocked.
  • deflection may be understood to mean a change in length or, in general, a change in the 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 may be greater than a distance between the chassis rotation axis and the chassis-side bearing surface. This may mean that the chassis rotation axis lies outside the bearing of the rocker on the chassis. As a result, an improved power transmission when lifting or holding the chassis can be achieved. In addition, the lifting device can be made so compact.
  • variable-length adjustment member is configured to change the position of the rocker with respect to the chassis or the chassis by changing its length.
  • the position of the rocker clearly defined operating conditions can be provided, which can be adjustable, for example, as discrete settings, in particular even if the lifting device allows a stepless adjustment of the height of the chassis with respect to the chassis.
  • the ratio of the amount of the portion of the connection vector between the rocker-side linkage point and the trolley rotation axis that is perpendicular to the longitudinal direction of the variable-length adjustment element is equal to the amount of the horizontal direction-extending portion of the linkage between the trolley axis of rotation and the chassis Rotation axis greater than 0.5, than 0.7, as 1, as 1.3, as 1.5 or as 2.
  • the ratio described above may be above one of the specified limits over the entire adjustment range of the chassis height. But it may also be sufficient if this is the case in a maximum lowered or a maximum angeho-benen state of the chassis or in at least one intermediate raising state of the chassis.
  • variable-length adjustment member preferably extends at least substantially along a horizontal direction.
  • the weight of the chassis acting at least substantially along a vertical direction is at least partially absorbed by the rocker or the chassis-side and the chassis-side bearing surface and does not have to be completely supported by the variable-length adjustment element. This contributes to the stability of the entire arrangement.
  • the fact that the variable-length adjustment element extends at least substantially along a horizontal direction may mean that a horizontal component of the extension direction of the variable-length adjustment member is greater than a vertical component of the extension direction of the variable-length adjustment member, and / or an inclination angle between the variable-length adjustment member and a horizontal plane does not exceed 10 °, 15 °, 25 ° or 45 °.
  • the chassis-side pivot point is at least in some operating positions with respect to the installation direction before or behind the chassis axis of rotation and / or the chassis axis of rotation. So a good power transmission can be achieved due to leverage.
  • a lower stop may be provided on the chassis, which is configured to secure the chassis in a maximally lowered state of the chassis by engagement with the rocker against further lowering.
  • the variable-length adjustment is relieved in the maximum lowered state of the chassis.
  • the maximum lowered Condition of the chassis firmly defined by the stop.
  • the lower stop also serves as a backup in case of malfunction of the lifting device.
  • An upper stop may be provided on the chassis, which is configured to secure the chassis in a maximally raised state of the chassis by engagement with the rocker against further lifting. Such an upper stop serves as a safeguard against over-rotation of the lifting device.

  • a hydraulic cylinder can be well integrated into a usually already provided on a paver hydraulics and allows the transfer of large forces.
  • the variable-length adjusting element could also be a spindle drive. This could achieve a purely mechanical solution.
  • the paver may further comprise an actuator for varying the length of the variable length adjustment member.
  • an actuator can be for example a hydraulic pump for actuating a hydraulic cylinder or a motor for actuating a spindle drive.

  • the locking element may be a locking bolt provided on the chassis, which is extendable for locking engagement with a locking structure, for example an opening or a depression, of the rocker.
  • the locking element can be horizontally, in particular perpendicular to the installation direction, extendable.
  • the chassis may be pivotally mounted to the landing gear at the front of the paver, so that when the chassis is lifted asymmetrically along the direction of installation, there is no tension between the chassis and the chassis.

  • the lower edge 73 is arranged at a distance g from a substrate 85.
  • the distance h is defined between the chassis 3 and the ground 85.
  • FIG. 7B is the chassis 3 with respect to the chassis 5 to a lifting i compared to in FIG. 7A lowered position shown.
  • the distance g between the lower edge 73 and the ground 85 is opposite FIG. 7A stayed the same.
  • FIG. 8 is a schematic representation of the coupling mechanism 75 according to another embodiment.
  • the coupling mechanism 75 comprises a control unit 87.
  • a control unit may be provided.
  • the coupling mechanism 75 according to this embodiment may include a sensor unit 89. This may be configured to measure or determine the distance g between the lower edge 73 and the ground 85 and / or the lift i and / or the distance h between the chassis 3 and the ground 85.
  • the sensor unit 89 may be connected to the control unit 87 in order to transmit measured or detected values to the control unit 87.
  • the coupling mechanism 75 may further comprise an actuator unit 91.
  • This may be connected to the control unit 87 to receive control signals.
  • the actuator unit 91 may also be connected thereto to receive control signals.
  • the actuator unit 91 may include an actuator 93. This can be configured to to move the material deflector 71, in particular to pivot.
  • Actuator 93 may be any suitable actuator known to those skilled in the art. In particular, electrical, hydraulic, electro-hydraulic or pneumatic actuators are conceivable, for example an electric or servomotor, or a hydraulic cylinder. Accordingly, it may be at the control unit 87 z. B. to act an electrical, hydraulic, electro-hydraulic 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 may then be configured to transmit control signals to the actuator unit 91 based on the received distance, causing the actuator unit 91 to drive the actuator 93 such that the distance g between the lower edge 73 and the ground 85 remains constant ,
  • the sensor unit 89 can detect the approach i and transmit it to the control unit 87. Based on the lifting height i, the latter can determine a desired position of the material deflector 71, which is assigned to the detected lifting height i.
  • An assignment of a lifting height i to a position of the material deflector 71 can be made by mathematical formulas or tables.
  • the control unit 87 transmits the desired position to the actuator unit 91 and independently controls or regulates the actuator 93 such that the material deflector 71 assumes the received desired position.
  • the control unit 87 itself comprises a controller, and transmits only control signals to the actuator 91.
  • FIG 9A is a side view of a chassis 5 of a road paver 1 shown according to another embodiment.
  • a chassis protection 95 is provided. This can for example, as shown in the embodiment, be attached to the crawler support 37.
  • the chassis 3 is completely lowered relative to the chassis 5.
  • the undercarriage 95 is hidden behind the chassis 3 as seen in the direction of travel.
  • the chassis 3 prevents the built-in material from entering the area of the chassis 5.
  • FIG. 9B the chassis 3 is raised relative to the chassis 5.
  • the chassis protection 95 can be exposed.
  • the undercarriage 95 can prevent the vehicle from entering the area of the chassis 5. It can also be seen that without the undercarriage 95 between the lower Edge of the chassis 3 and the substrate would be significantly more space that would allow the built-in to get into the area of the chassis.
