Definitions

  • the present invention relates to road pavers with a chassis that can be raised relative to the chassis at least in a rear region of the road finisher.
  • Known asphalt pavers include a bunker for receiving paving material in front of the paver with respect to an installation direction.
  • the paving material is conveyed from the material bunker into a rear area of the paver during installation by means of a suitable longitudinal conveyor.
  • the paving material is distributed transversely to the direction of paving by means of a distributor screw, and is thus evenly presented to a paving screed pulled by the paver to compact the paving material.
  • the paver can be adapted for the installation of different layer thicknesses.
  • the auger can be raised in relation to the chassis in order to install thicker layers.
  • a disadvantage of such a system is that the position of the auger relative to the chassis is changed significantly upwards in order to install very thick layers. This can lead to the situation that the distributor screw at least partially blocks a material outlet of the longitudinal conveyor. This reduces the throughput of paving material to the screed, which is particularly disadvantageous for large layer thicknesses, since an increased amount of paving material is required for this.
  • a road paver is known, the rear area of which can be raised for the installation of large layer thicknesses. This is achieved by means of a vertical guide which can be adjusted in height by means of a hydraulic actuating cylinder between a crawler chassis and a chassis of the paver in the rear area of the paver. In a front area, the chassis is rotatably mounted on the crawler track.
  • the disadvantage of this system are the high ones Loads on the hydraulic actuating cylinders, which essentially carry the weight of the chassis completely. Correspondingly high forces are required for height adjustment.
  • the paver's stability also suffers.
  • the disk can be rotated in its storage on the chassis by means of a hydraulic cylinder.
  • a hydraulic cylinder When the disk rotates, the mutual height relationship between the chassis and the chassis in a rear area of the paver changes due to the eccentricity of the connection between the disk and the chassis.
  • the weight of the chassis no longer has to be borne entirely by the hydraulic cylinder, it still has to exert high forces to rotate the disk when the chassis is lifted. Even when the chassis is held at a certain height, high loads are exerted on the hydraulic cylinder.
  • the road paver according to the invention comprises a chassis with two traction tracks and a chassis. It also includes a bunker attached to the chassis at the front of the paver to accommodate paving with respect to an installation direction and a screed to compact paving from the paver at the rear with respect to the installation direction, which is attached to the chassis by tie bars. In addition, it comprises a lifting device which is designed to lift the chassis relative to the chassis at least in a rear area of the paver.
  • the road paver according to the invention is characterized in that a material deflector which is movable, in particular pivotable, relative to the chassis is arranged between the two traction lanes.
  • a displaceable material deflector is also conceivable.
  • Such a can be designed as a slidable plate.
  • a slidable plate can e.g. B. can be slidably received in a recess on or in the chassis and pushed out of this to extend the material deflector.
  • pivotable material deflectors on the one hand and extendable material deflectors on the other hand can have different advantages and technical effects.
  • the terms "extended / collapsed” and "extended / retracted” as well as “extended / retracted” and “expand / collapse” are used synonymously, although the variants are not obvious equivalents.
  • the undercarriage can be designed as a chain undercarriage or a wheel undercarriage and support the chassis.
  • the arrangement of the material deflector between the traction tracks can prevent the installation goods from penetrating into the space between the traction tracks or between the chassis and the ground.
  • the movable design of the material deflector can on the one hand ensure that its arrangement can be adapted to different lifting heights of the chassis.
  • the material deflector can be carried along on the paver in a folded position. This can make disassembly after lowering as well as assembly during or before lifting unnecessary.
  • 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 of the chassis from a base and / or a lifting movement between the chassis and the chassis and / or the distance from a lower edge of the material deflector to the base. This enables monitoring, control or regulation of the lifting process and / or the swiveling process of the material deflector.
  • the actuator unit is configured to move, in particular to pivot, the material deflector based on signals generated by the sensor unit.
  • the (swivel) 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 surface is continuously recorded and that it can be kept constant by regulating the (swivel) position of the material deflector even when the chassis is raised.
  • 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 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 lifting device comprises a rocker, which is mounted on a chassis-side bearing surface and can be rotated about a chassis axis of rotation and is rotatably mounted on a chassis-side bearing surface about a chassis axis of rotation.
  • the storage area on the chassis side can be a storage area that is part of the chassis or is at least firmly connected to the chassis.
  • the storage area on the chassis side can be a storage area that is part of the chassis or is at least firmly connected to the chassis.
  • the chassis axis of rotation and the chassis axis of rotation are preferably parallel to one another and in particular each run in a horizontal plane and perpendicular to the direction of installation, that is to say in a transverse direction of the paver.
  • the chassis axis of rotation and the chassis axis of rotation is not identical.
  • the chassis axis of rotation and the chassis axis of rotation are preferably offset parallel to one another.
  • the lifting device also comprises a length-adjustable adjusting element which connects a chassis-side articulation point with a rocker-side articulation point and is configured to change a distance between the chassis-side articulation point and the seesaw-side articulation point and thus to change the chassis the chassis can either be raised or lowered.
  • the articulation point on the chassis side can be an articulation point that is part of the chassis or at least firmly connected to the chassis.
  • the rocker-side articulation point can be a articulation point that is part of the seesaw or is at least firmly connected to the seesaw.
  • the length-adjustable adjusting element can be articulated to the chassis-side articulation point and the rocker-side articulation point.
  • a first end of the length-adjustable adjustment element is articulated to the chassis-side articulation point and a second end of the length-variable adjustment element is articulated to the rocker-side articulation point.
  • the length-adjustable adjusting element extends on one or both sides beyond the respective articulation point.
  • the paver can comprise a coupling mechanism which is configured to pivot the material deflector relative to the chassis when the lifting device lifts the chassis relative to the chassis.
  • a coupling mechanism configured to pivot the material deflector relative to the chassis when the lifting device lifts the chassis relative to the chassis.
  • the coupling mechanism can have a deflection lever which is rotatably attached to the chassis.
  • the coupling mechanism comprises a regulating or control unit which is connected to the sensor unit and the actuator unit, the regulating or control unit actuating the actuator unit as a function of signals received from the sensor unit.
  • chassis protection is provided which is arranged behind one of the traction tracks in the direction of installation. This can prevent the installation goods arrives at the paver's traction elements and can, for example, negatively influence their traction properties there.
  • disadvantages as already described above with reference to the installation material coming under the chassis, can be avoided.
  • chassis protection is covered by the latter towards a rear of the road paver in a position of the chassis which is at a maximum lowered relative 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 chassis protection into a desired position. Rather, the undercarriage protection can be provided in a suitable position and can only be used when the chassis is raised.
  • the actuator unit and or the coupling mechanism can have an elastic element.
  • an elastic element can prevent damage to the actuator unit or the coupling mechanism, for example if the material deflector encounters or is blocked by objects when moving and / or swiveling or when driving the paver finisher.
  • the elastic element can be prestressed.
  • the elastic element is configured to be deflected when the movement and / or pivoting of the material deflector is blocked.

  • 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 axis of rotation and the chassis axis of rotation can be greater than a distance between the chassis axis of rotation and the chassis-side bearing surface. This can mean that the chassis axis of rotation lies outside the bearing of the rocker on the chassis. This enables improved power transmission to be achieved when lifting or holding the chassis.
  • the lifting device can be made compact.
  • the length-adjustable adjusting element is preferably configured to change the position of the rocker in relation to the chassis or the chassis by changing its length.
  • the position of the rocker can thus provide clearly defined operating states, which can be set, for example, as discrete settings, especially when the lifting device allows a continuous adjustment of the height of the chassis in relation to the chassis.

Because of a leverage effect, particularly good power transmission when lifting or holding the chassis is achieved by the length-adjustable adjusting element.
  • the ratio described can be above one of the limit values mentioned, in particular over the entire setting range of the chassis height. However, it may also be sufficient if this is the case when the chassis is in a maximally lowered or a maximally raised state or in at least an intermediate lifting state of the chassis.
  • the length-adjustable adjusting element preferably extends at least substantially along a horizontal direction.
  • the weight of the chassis which acts at least essentially 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 carried completely by the length-adjustable adjusting element.
  • That the variable-length adjustment element extends at least substantially along a horizontal direction can mean that a horizontal component of the direction of extension of the variable-length adjustment element is greater than a vertical component of the extension direction of the variable-length adjustment element, and / or that an inclination angle between the variable-length adjustment element and a horizontal plane does not exceed 10 °, 15 °, 25 ° or 45 °.

  • a locking element is preferably provided, which is configured to mechanically lock the rocker in a defined relative position with respect to the chassis.
  • the chassis can be mechanically held at a defined height, thus relieving the adjustable element.

  • Figure 7B is the chassis 3 relative to the chassis 5 by a lifting movement i compared to the in Figure 7A shown position lowered.
  • the distance g between the lower edge 73 and the base 85 is opposite Figure 7A stayed the same.
  • Figure 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 can also be provided.
  • the coupling mechanism 75 according to this exemplary embodiment can have a sensor unit 89. This can be configured to measure or determine the distance g between the lower edge 73 and the ground 85 and / or the lifting movement i and / or the distance h between the chassis 3 and the ground 85.
  • the sensor unit 89 can be connected to the control unit 87 in order to transmit measured or detected 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 it in order to receive control signals.
  • the actuator unit 91 can have an actuator 93. This can be configured to move the material deflector 71, in particular to pivot it.
  • the actuator 93 can be any suitable actuator known to the person skilled in the art.
  • electrical, hydraulic, electrohydraulic or pneumatic actuators are conceivable, for example an electric or servo motor, or a hydraulic cylinder.
  • it can be in the control unit 87 z.
  • 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 such that it transmits control signals to the actuator unit 91 based on the received distance 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 background 85 remains constant.
  • the sensor unit 89 can detect the lifting movement i and transmit it 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 using mathematical formulas or tables. It is conceivable that the control unit 87 transmits the target position to the actuator unit 91 and this 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 paver 1 according to another embodiment.
  • a chassis protection 95 is provided.
  • this can be attached to the crawler carrier 37.
  • the chassis 3 is completely lowered relative to the chassis 5.
  • the chassis protection 95 is covered by the chassis 3 in the direction of travel to the rear.
  • the chassis 3 prevents installation goods from getting into the area of the chassis 5.
  • the chassis 3 is raised relative to the chassis 5.
  • the chassis protection 95 can be exposed.
  • the undercarriage protection 95 can prevent installation goods from reaching the area of the undercarriage 5. It can also be seen that without the undercarriage protection 95 there would be significantly more space between the lower edge of the chassis 3 and the ground, which would allow the installation goods to get into the area of the undercarriage.
