Cl. thogona] axes hydraulic power means for effect- Int. Clthe winging about at least two of these axes
  • the ld 01 Search 404/123, 128, 280/419, swinging between the other two units is also powered, 280/442, 49 403 the drive to the connections between the units being alternative so that when one pair of units is being 1 References Clted swung relative to each other the other pair will idle,
  • a multiunit machine is caterpillar configurated, capable of forward and rearward operation, insuring track covering, and can be driven by a single operator, whose driving position can be selected, as desired, on any of the several units comprising the machine.
  • a use of particular interest for this machine is in selfpropelled tamping means.
  • An embodiment of the invention includes a centrally articulated combined roller comprising a set of vibrating metal drums and a set of multiple tired wheels, and a unit very similar to that provided with vibrating metal drum and connected to the tired-wheel unit by a universal joint type of steering, enabling the latter unit to rotate also about a transverse horizontal axis relative to the forward movement direction of the machine.
  • an actuator hydraulic piston which, by extending or retracting, causes the two units comprising the machine to rotate about the vertical axis of the steering articulation or joint.
  • Such an actuator is provided in multi-unit machines for each of the connecting steering articulated joints; however, for accurate both forward and rearward drive, these actuators are operated one at a time by the control zone, while the other are not, thus remaining idle,
  • the only actuator being driven is that at the first steering articulated joint in the movement direction.
  • the other actuators are idle and therefore the third unit as well as the succeeding units behave as actual mere trailers (this even if the (soil loading) rolling elements thereof which are in contact with the soil transmit a tangential thurst force thereto).
  • a distributing valve is inserted in the oleostatic control system and is controlled through the main lever used by the operator for motion reversal.
  • FIG. 1 is an elevational view showing a triple-drive self-propelled tamping roller comprising three interarticulated units, as hereinafter described;
  • FIG. 2 is a plan view of the same machine
  • FIG. 3 is a diagrammatic elevational view showing the steering articulated joint also enabling a rotation about a longitudinal horizontal axis, as well as about a transverse horizontal axis;
  • FIG. 4 is a plan view of the articulated joint shown in FIG. 3;
  • FIG. 5 shows the oleostatic system diagram for alternately operating the two actuators.
  • a tamping machine shown in FIGS. 1 and 2 comprises a main unit 10 provided with an engine 11 and driving position 12 and bearing on the soil by a plurality of tired wheels 13. Instead of these multiple tired wheels, also a metal drum or other rolling system could be used.
  • This unit 10 is connected by a conventional steering articulated joint 14 to a unit 15 provided with a vibrating metal drum 16 or other tamping means, the rotary movement of which is provided by a power transmission system comprising a cardan shaft 17.
  • a power transmission system comprising a cardan shaft 17.
  • the main unit also includes a second steering articulated joint 18 located at the free opposite side, by which a third tamping unit 19 can be held connected, which third unit 19 is in turn provided with a rolling tamping means 20, preferably also vibrating, and also rotatably driven by a motion transmission system comprising a cardan shaft 21.
  • Both of the two steering articulated joints l4 and 18 are provided inter alia with horizontal actuators 22, 23, serving the purpose of controlling and adjusting the mutual angle in the horizontal plane for the three tamping units l0, l5 and 19.
  • the articulated joint 18 is made to enable the two units 10 and 19, as connected thereby, to rotate not only about a vertical axis 24 (FIG. 3), but also about a longitudinal axis 25 and about a transverse horizontal axis 26. Moreover, all of these three freedoms of rotation must continuously controlled by the operator, so as to adjust these capabilities of rotation and to stop the same. To this end, this joint could be made as shown in FIGS. 3 and 4, that is applying a plate 27 to the free surface of unit 10, two identical opposite rigid bearings 28 and 251 being carried thereon and supporting an element 30 rotatably carried about the vertical axis 24.
  • Two horizontal arms 32, 32 are mounted on said body or element 30, extending about the transverse horizontal axis 26 and at the ends thereof engaging the element 33 comprising a cylindrical portion 34.
  • this body or element 33 is capable of rocking about the transverse horizontal axis 26, but this rocking movement thereof is controlled by the actuator 35, the cylinder of which is rotatably mounted on said body 33, while the associated piston is rotatably mounted on said element 30.
  • the cylindrical body or portion 34 has a coaxial cylindrical internal cavity, the axis 25 of which is longitudinally horizontal.
  • a cylindrical body 36 engages in said cavity and in turn is fast with the plate 37 which is carried on the surface of the free wall of the tamping unit 19.
  • a latching device 38 capable of stopping the relative movement.
  • the actuator 23 is used for controlling the rotation of the two units 10 and 19 about the vertical axis 24.
  • these actuators may comprise oleostatic pistons operable by admitting high pressure oil from a conventional servo-steering system.
  • these pistons will be alternately operated in order to avoid undue slidings on the soil as would be caused by a concurrent drive of the two pistons.
  • the actuator 22 will be operated when the compactor is moving having the unit 15 as its front part, and at the'same time the actuator 23 will be disconnected. Conversely, still in the same. embodiment, when the machine is operating in the opposite direction (and hence its front part is the tamper 19), it is the actuator 23 that should be operated, while at the same time the actuator 22 will be disconnected.
  • FIG. 5 diagrammatically shows an oleostatic system according to the invention, wherein reference numeral 40 designates the main oil tank, from which the oil is drawn by a pump 41 through a filter 42 and delivered under pressure to a rotating distributor 43 operated by the machine steering wheel. Pressure oil reaches the distributor 43 through a piping 44 having a limiting valve 45 inserted therein. Normally, two pipings 46 branch off from the distributor 43 (of which one is a delivery piping and the other a return piping), directly leading to the steering actuator.
  • said pipings 4-6 enter a two-position electro-distributor 47. At one of these positions, oil in pipings is directly supplied to the pipings 48 of actuator 24 and the pipings 49 of actuator 23 are shut off, whereby the piston stem 50 can freely move without providing any resistance.
  • the distributor 47 takes its other position, then the pipings 46 are directly connected with the pipings 49,
  • the electro-distributor 47 takes either of the said two positions depending on whether the electromagnet 52 is energized or not by electric power. To this endQthe electrical current from a power supply 53 is supplied through electrical conductors 54 until. reaching a switch 55 controlled by a cam 56, the latter being connected to a lever on the pilot bridge.
  • This lever 57 is for imparting forward and rearward movement to the machine and hence determines the running reversal.
  • a multiple machine for compacting soil and the like comprising three compacting units interconnected by steering articulated joints, at. least one of said joints interconnecting the two adjacent units for rotation relative to each other about three orthogonal axes, and
  • a machine as claimed in clah4 and power means for swinging the other two units relative to each other about at least a vertical axis, and. means for selectively actuating the power means associated with only one pair of said units at a time.
  • said power means comprising means for selectively swingingsaid two units relative to each other about a vertical axis and about a horizontal axis transverse to the path .of moveent of said machine.
  • connection of said two units for rotation about said three orthogonal axes comprising an upright body mounted for rotation about a vertical axis on one of said units, a cylindrical body mounted on said upright body for vertical swinging movement about a first horizontal axis passing through said vertical axis, and means secured to the other said unit of said two units and rotatable on and relative to said cylindrical body about a second horizontal axis coaxial with said cylindrical body and perpendicular to said first horizontal axis and perpendicular to and passing through said vertical axis.
  • said cylindrical body encompassing said means on said other unit, a hydraulic jack interconnecting said cylindrical body and i said one unit to swing said two units relative to each other about said vertical axis, and a hydraulic jack interconnecting said cylindrical body and said upright selectively engageable between said cylindrical body body to swing said units relative to each other about and said other unit to prevent rotation of said units relsaid first horizontal axis. ative to each other about said second horizontal axis.
