Definitions

  • the invention relates to a vehicle, in particular an earth-moving machine according to the preamble of claim 1, inter alia, with an undercarriage and an upper carriage mounted thereon rotatable about an axis of rotation, a drive means for rotating the upper carriage relative to the undercarriage and a locking device for determining a relative position of the upper carriage undercarriage.
  • Such a vehicle which in the DE 198 13 521 A1 is therefore described, in addition to the drive means comprises a locking device for determining the position of the upper carriage relative to the position of the undercarriage.
  • the in the DE 198 13 521 A1 Locking device described is based on a turntable with a toothing, in which engages a brake pad and so produces a positive connection between the superstructure and the undercarriage.
  • the known locking device allows a very effective fixation of the relative position of the upper carriage to Undercarriage.
  • a speed monitoring device is additionally necessary, which can only retract the brake pad in the turntable, when the rotational movement of the upper carriage has come to a safe stop.
  • the JP-A-07048859 discloses a crane vehicle with an undercarriage and a relatively rotatable superstructure. To brake a movement between the uppercarriage and the lowercarriage, a disk-shaped or cylindrical surface can be provided according to this document, on which two retaining elements can be brought into abutment.
  • JP-A-09142787 of the JP-A-58024627 as well as the DE-A-1 904 954 known.
  • An object of the invention is to provide a vehicle with a simple and at the same time effective and reliable locking device for determining the relative position of the superstructure to the undercarriage.
  • a vehicle with the features of claim 1. Preferred embodiments are given in the dependent claims.
  • a holding surface is formed concentric to the axis of rotation, at least one clamping element on the undercarriage or on the uppercarriage is adjustably arranged and for force-locking connection of the upper carriage with the lower carriage an actuator is provided by which the clamping element is movable relative to the holding surface.
  • a basic idea of the invention is that the clamping element is spaced apart from the holding surface during the intended turning of the upper carriage relative to the lower carriage by means of the drive device.
  • the clamping element with the holding surface in connection brought and thereby made a non-rotatable connection between the superstructure and the undercarriage due to the static friction forces between the clamping element and the support surface, so that an undesired rotation of the upper carriage against the undercarriage is effectively prevented. Since no ring gear for the locking device is required, a stepless locking can be done with a simplified design.
  • the clamping element In principle, it is possible to arrange the clamping element on the undercarriage and the holding surface on the superstructure.
  • the energy supply of a generic vehicle is generally located in the superstructure, there is a particularly easy to manufacture and therefore preferred embodiment is that the clamping element on the upper carriage and the support surface is arranged on the undercarriage.
  • this embodiment allows short cable paths between adjusting elements and energy supply.
  • the support surface formed concentrically to the axis of rotation could basically be formed as a surface of a plurality of geometric bodies.
  • the holding surface could be formed on a conical, disc-shaped or annular wall, which may also have spokes or recesses.
  • the holding surface is formed on a cylindrical wall. This allows a particularly simple structural design with a high strength of the wall when pressing the clamping element. If the cylindrical wall is arranged on the undercarriage, then it can in particular also engage through a recess in the uppercarriage. On the other hand, if the wall is arranged on the uppercarriage, then it can intervene in particular in the lowercarriage.
  • the movement of the clamping element according to the invention relative to the holding surface can be carried out by a movement of the clamping element, the holding surface or both.
  • a particularly economical embodiment is achieved in that only the clamping element is movable.
  • two clamping elements are arranged opposite each other and on both sides of a wall with two retaining surfaces and that preferably the opposite clamping elements by the actuator at the same time against the retaining surfaces are pressed.
  • a plurality of walls may be provided with retaining surfaces arranged thereon.
  • a coaxially arranged stack of disk-shaped walls is conceivable, wherein each wall is assigned one or more clamping elements.
  • a force symmetrical particularly favorable arrangement is achieved in that three or more pairs of clamping elements are distributed on the wall with the concentric support surfaces. As a result, deformations and unwanted distortions of the wall during operation of Erdbaumwerkmaschines are largely prevented.
  • the clamping element pairs are arranged equidistantly along the wall. If there are three pairs of clamping elements, the angle enclosed by two adjacent pairs of clamping elements on the axis of rotation is 120 °.
  • the frictional connection of the upper carriage with the undercarriage can be improved in that the clamping element has a friction lining on its surface which is in contact with the holding surface.
  • This friction lining should preferably have a high coefficient of static friction and may also be provided with a roughened, wear-resistant surface, so that it can also participate in a certain braking of the rotational movement.
  • the holding surface formed concentric with the axis of rotation may have a friction lining.
  • the actuator for pressing the clamping element to the support surface may comprise electromagnetic, mechanical, pneumatic or other drive means. Particularly high pressure forces and thus a particularly efficient frictional connection of the superstructure with the undercarriage, however, can be achieved in a preferred embodiment in that the actuator has a hydraulic actuating cylinder.
  • the actuator can be controlled by a control device so that the clamping element is pressed against the retaining surfaces only after completion of the rotational movement of the upper carriage.
  • the control can also be such that the clamping element supports the stopping of the rotational movement of the upper carriage. The clamping element remains in the locking position until a further pivoting of the upper carriage takes place.
  • the clamping element is slidably mounted and prestressed by a spring tensioning device, wherein the spring tensioning means presses the clamping element for locking the upper carriage against the support surface, and that moves to release the upper carriage of the actuator, the clamping element against the bias of the spring tensioning device.
  • the actuator When the actuator is switched off when at rest or in the event of an energy interruption, the superstructure is always fixed.
  • the actuator can be coupled to the rotary drive of the upper carriage such that activated at a desired pivotal movement of the upper carriage of the actuator and so the superstructure is released.
  • the actuator is deactivated, so that the pivot position achieved by the spring-loaded locking device is fixed.
  • the locking device can be arranged according to the invention so that the relative movement of the clamping element to the support surface during pressing and when removing the clamping element in a direction which is approximately perpendicular to the support surface, takes place.
  • a particularly robust construction of the invention is characterized achieves that a Keilschiebermechanismus is provided for pressing the clamping member to the support surface.
  • a first wedge may be provided with a first wedge surface on a piston rod of an actuating cylinder, which has an angle to a longitudinal axis of the printing cylinder. The first wedge surface slidably abuts a second wedge surface of a second wedge which is formed on the clamping element.
  • a particularly robust construction can also be achieved in a preferred embodiment by providing a toggle mechanism for pressing the clamping element against the holding surface.
  • a vehicle 10 according to the invention shown as a carriage of an earth-moving machine, is shown schematically in FIG.
  • the vehicle 10 comprises a superstructure 1 and an undercarriage 2, which are rotatably supported relative to one another about an axis 47 about a rotation axis 5.
  • the uppercarriage 1 comprises a driver's cab 41 and a housing 42 for control, cooling and power supply modules and for counterweights.
  • On the undercarriage 2 is designated in its entirety by 43 Chassis provided which has caterpillars 44.
  • a cylindrical wall 31 is arranged on the undercarriage 2 is rotationally fixed and concentric with the axis of rotation 5.
  • the crown of the drum-shaped wall 31 protrudes up to the superstructure 1.
  • the foot of the wall 31 is welded to a support frame of the undercarriage 2.
  • a locking device 20 is formed on the uppercarriage 1, which is shown in Fig. 2 in the locked position.
  • the locking device 20 comprises an outer clamping element 21 for abutment with an outer retaining surface 23 and an inner clamping element 22 for abutment with an inner retaining surface 24.
  • the retaining surfaces 23 and 24 are formed by the peripheral surfaces of the cylindrical wall 31.
  • Both clamping elements 21, 23 are mounted radially displaceable to the axis of rotation via adjusting jaws 25 and 26 on the superstructure 1.
  • the application of the clamping elements 21, 22 to the support surfaces 23, 24 by means of an actuator 28, which moves the adjusting jaws 25, 26 against each other and presses against the wall 31.
  • the clamping elements 21, 22 are releasably attached, which each have a friction lining 29, 30 on its contact side.
  • a pair of clamping elements 21, 22 is provided on both sides of a wall 31, of which only the inner clamping element 22 will be described in more detail below.
  • a friction pad 30 is mounted on the side facing the wall 31, which is wear-resistant and ensures a good positive connection.
  • the plate 33 is fixedly connected to its rear side with a sliding sleeve 34 which is mounted on a cylindrical pin 35 slidably.
  • the sliding sleeve 34 On its inner side, the sliding sleeve 34 has an annular recess in which a ring-shaped disk spring package is arranged as a spring tensioning device 36. This relies on the one hand against a shoulder of the sliding sleeve 34 and on the other hand from a flange on the bolt 35, and thus presses the friction pad 30 radially against the wall 31st
