Definitions
- the invention relates to a road construction machine for processing road surfaces, e.g. of road surfaces made of concrete, asphalt or the like. according to the preamble of claim 1.
- Road construction machines of this type are used, for example, as cold milling machines for removing road pavements.
- a device for milling off road surfaces is known in which pivotable support wheels are attached to a height-adjustable milling drum.
- the jockey wheel is pivoted about a vertical axis.
- the jockey wheel is also height adjustable.
- the swivel position of the support wheel can be locked with the help of bolts.
- These support wheels serve to keep the milling depth of the milling drum constant. They are not driven and do not bear the machine weight supported by the chassis.
- All-wheel drive is provided for newer milling machines, so that the axis extending support wheels are also driven.
- the support wheels can be telescoped with the aid of hydraulic cylinders and bear the machine weight.
- the milling drum is arranged at the rear end of the machine frame and extends with its one end face close to the so-called zero side, at which the end face of the milling drum is almost flush with the side edge of the machine frame.
- the milling drum is thus arranged approximately flush and parallel to the rear of the machine frame. Because the milling depth can be adjusted directly, the support wheels are located at the level of the roller axis of the milling drum.
- the support wheel arranged on the zero side which in the normal first end position protrudes laterally beyond the zero side, can be pivoted inwards relative to the machine frame, so that work can be carried out close to the edge.
- the jockey wheel is pivoted about a vertical swivel axis, the jockey wheel being mounted at two points on the machine frame with a large vertical distance in order to achieve sufficient stability to support the machine weight.
- the uniaxial bearing of the swivel device protrudes from the zero side, so that working close to the edge is possible, but not a flush approach to a house wall.
- the operator's platform is located on the machine frame above the milling drum.
- When milling close to the edge on the zero side and the support wheel and the uniaxial vertical mounting of the support wheel obstruct the unobstructed view of the working area in front of the milling drum, both in the swung-out and in the swung-in state.
- the swivel device requires a lot of space, it is not possible to place a cabin on the operator's platform.
- the ascent and descent of the Operate from behind which is disadvantageous in terms of safety.
- Another disadvantage is that the direction of rotation of the support wheel is changed by pivoting. As a result, it is necessary to change the direction of rotation of the hydraulic drive for the support wheel or the support wheel must be rotatably mounted in the lifting column, an additional locking device then being necessary.
- the invention has for its object to develop a road construction machine of the type mentioned in such a way that with a support wheel pivotable on the zero side of the machine, the unobstructed view of the working area in front of the working device is improved when working close to edges.
- the invention advantageously provides that the pivotable support wheel can be pivoted from the first outer end position into the inner end position via a gear lying in a horizontal plane. Due to the horizontal position of the gearbox, the vertical space required for the swivel device of the support wheel is considerably reduced, so that the support wheel with the swivel device allows a better view of the working area in front of the work device both in the swiveled-out and in the swiveled-in state.
- the transmission can advantageously be arranged in a plane below the operator's platform, so that the driver can observe the working surface in front of the working device without hindrance.
- the arrangement of the transmission also enables a cabin to be placed on the driver's station, with direct access to the driver's station from the side being possible.
- the pivotable support wheel can be pivoted while maintaining the running direction, the support wheel being arranged in parallel in the inner end position. Maintaining the running direction has the advantage that the drive for the support wheel does not have to be switchable in its direction of rotation.
- rectangular or square lifting columns can be used in cross-section, which are more favorable in terms of directional stability. In the case of lifting columns with a round cross section, the support wheel is not rotated by 180 °.
- the transmission preferably consists of a link transmission.
- Such a gearbox can absorb high vertical forces despite the small vertical expansion, since it can be supported on two horizontally spaced vertical bearings.
- the steering gear can be coupled to a drive device, so that the pivoting of the support wheel can be initiated by the vehicle driver on the control station at a control panel.
- the handlebar gearbox can consist of a four-bar linkage with four vertical articulated axes and two links which can be pivoted in a horizontal plane.
- the vertical load on the machine frame and on the supporting wheel is distributed over two vertical articulated axes, so that the machine weight with high stability even with a shortened vertical extension of the Swivel device can be supported.
- the machine-side joints are located in the machine frame and do not protrude from the zero side. In this way, it is possible not only to work close to the edges, but also to drive flush to a house wall. Compared to a uniaxial design of the swivel device, there is a smaller lateral stroke between the two end positions of the support wheel, so that less space is required for the outer end position of the support wheel, as a result of which the machine is not unnecessarily widened.
- the working device can consist of a milling drum, one end side of which is approximately flush with the zero side.
- the milling drum axis extends orthogonally to the direction of travel of the road construction machine.
- the working device is preferably arranged at the rear end of the machine frame and is approximately flush with it. In this way it is possible not only to have the working device work close to the edge, but also into corners.
- the rear support wheels are height-adjustable to adjust the working depth of the work equipment.
- the rear support wheels and / or the at least one support wheel of the front chassis axle can be driven.
- the swiveling support wheel can be fixed in its respective end positions with the aid of a locking device.
- a simple mechanical locking device consists, for example, of bolts that are inserted through parts of the gearbox and the machine frame.
- the joints or the joint axes of the link mechanism are fastened to at least one support plate which is connected to the lifting column in a manner fixed against relative rotation.
- the joints are attached to the support plate on the side facing the machine frame.
- the support plate ensures stable guidance of the support wheel.
- the link mechanism can have a drive device consisting of a push rod with a linear drive and two link arms. The pivoting movement of the support wheel can then be carried out by actuating the linear drive.
- the rear support wheels are steerable.
- Fig. 1 is a schematic side view of the road construction machine
- Fig. 2 is a plan view of the road construction machine according to
- Fig. 1 shows a support wheel in an outer end position
- Fig. 3b the support wheel in an intermediate position
- Fig. 3c the support wheel in the inner end position.
- Fig. 1 shows a road construction machine for milling off Roadways with a self-propelled undercarriage consisting of a steerable front undercarriage axle 6 with two support wheels 12 driven by a hydraulic motor and two mutually independent rear support wheels 14, 16.
- the undercarriage carries a machine frame 8 on which a driver's station 4 is located on the so-called zero side 24 of the road construction machine at the level of the axes of the support wheels 14, 16 according to FIG. 2.
- the rear support wheels 14, 16 can be adjusted in height with the aid of a lifting column 48, so that the working depth of a working device 20 consisting of a milling drum can be set.
- the milling drum 20 is almost flush with its one end face with the zero face 24 of the machine frame, so that work close to the edge is possible on the zero face of the road construction machine.
- the support wheel 16 is pivoted inward from an outer end position 26 beyond the zero side plane into a recess 18 in the machine frame, so that the outer edge of the support wheel 16 is flush with the zero side 24.
- the support wheels 14, 16 are driven by a hydraulic motor. As best seen in FIG. 1, the milling drum axis runs in the same vertical plane as the axes of the support wheel 14 and the support wheel 16 in the outer end position.
- the engagement circle of the milling drum ends in the vicinity of the rear end of the machine frame 8, so that milling can be carried out in corners up to the edges.
- the pivoting device for the support wheel 16 consists of a link mechanism 30 with four vertical joint axes having joints 40, 41, 42, 43 and with two in one horizontal plane pivotable handlebars 44.46.
- Two joints 40, 41 are fixed in place on the machine frame 8 and two joints 42, 43 are provided on the pivotable support wheel 16 in each case in two vertically spaced support plates 38, 39.
- Articulation pins 56, 58, 60, 62 are mounted coaxially to the vertical articulation axes.
- the link 46 can be pivoted at one end about the pivot pin 56 mounted in the machine frame 8 and at its other end with the pivot pin 62 mounted between two vertically spaced support plates 38, 39.
- the link 44 can be pivoted on the machine side about the hinge pin 58 which is mounted in the machine frame 8 and is articulated on the side of the support wheel 16 with the hinge pin 60 which is mounted between the support plates 38, 39.
- the links 44, 46 thus move between the vertically spaced support plates 38, 39.
- 3a to 3c show the pivoting process in which the support wheel 16 is moved from its outer end position 26 into the inner end position 28 with the aid of a drive device 34.
- the drive device 34 consists of a hydraulic piston-cylinder unit 33 with a push rod 35 and two link arms 36, 37.
- the link arm 37 is designed as a two-armed lever, one end being mounted on the machine frame 8 and the other end with the second Handlebar arm 36 is articulated. The other end of the second link arm 36 is connected to the link 44 of the swivel device.
- the push rod 35 can be actuated by the driver on the operator's platform 4.
- the support wheel 16 In the retracted position of the push rod 35, the support wheel 16 is in its outer end position 26, which projects beyond the zero side 24.
- the link mechanism 30 is pivoted so that the support wheel 16 can be moved into the inner end position 28.
- the support wheel 16 is raised with the aid of the lifting column 48, so that the support wheel 16 can be pivoted without contacting the ground.
- the link mechanism 30 can be fixed with the aid of a bolt, not shown in the drawings, which is inserted through corresponding locking holes.
- a locking hole 50 is provided in the machine frame 8, which is aligned with a push-through opening 52 in the handlebar 44 in the end position 26. The bolt can then be inserted through both openings 50, 52 and thus lock the steering gear 30.
- the steering gear 30 is locked with the aid of locking holes 54 in the support plates 38, 39.
- the bolt is inserted through the upper support plate 38, through the through opening 52 in the handlebar 44 and through the lower support plate 39.
- neither the support wheel 16 nor any transmission element of the link mechanism projects beyond the zero side 24.
