Definitions
- the invention relates to a motor road roller according to the preamble of claim 1.
- the invention is in road construction and in particular for technical means for the compaction of road building masses, d. H. for road rollers, can be used.
- motorized road rollers are used with both an articulated and a rigid support frame.
- the development of the invention relates to road rollers with a rigid support frame and thereby on the roll drum system.
- a construction of a motor road roller with a rigid support frame is known.
- the supporting frame is supported at the bottom by a pair of working members designed as rollers.
- One roller unit in each case comprises a roller.
- at least one of the roller units is designed to be pivotable about a steering axle which projects vertically on the support frame.
- Each of the roller units has a ⁇ -shaped (U-shaped) frame, between whose legs the roller is rotatably mounted about its central axis.
- the frame engages around the roller and is supported on the central axis.
- the steering mechanism comprises a vertical pivot axis, which coincides with the steering axis.
- the vertical pivot axis is mounted on the ⁇ -shaped frame and more precisely on its adjacent to the support frame traverse.
- the pivot axis is part of the hinge bearing of the support frame.
- the pivot axis is kinematically connected to a drive.
- the drive is usually a hydraulic cylinder used.
- the steering mechanism is designed so that geometric center and steering axes perpendicular to each other and intersect. Understandably, the physical center and pivot axes are only perpendicular to each other and do not intersect.
- the main deficiency of this known construction is that the steering mechanism used has a limited swing angle. This gives no possibility to increase the Einwalzbreite and consequently to increase the work of the compaction work.
- the mentioned defect relates to a road roller with two steerable roller units.
- such a steering mechanism substantially reduces the freedom of movement of the road rollers, which are equipped with only one steerable roller unit.
- the pivoting device of the ⁇ -shaped frame which includes a bearing unit, a drive and its kinematic connection with the pivot axis, arranged on the support frame and thus mechanically interconnected. This complicates the entire construction of the steering mechanism and deteriorates its repairability.
- DE 198 13 475 C1 discloses a motor road roller with a rigid support frame and with at least one working member designed as a roller. At least one roller unit is arranged on the support frame.
- the roller unit consists of a ⁇ -shaped (U-shaped) frame and a horizontal, cylindrical roller.
- the roller is rotatably supported between the free ends of the legs of the ⁇ -shaped (U-shaped) frame about its central axis. On their sides facing away from the free ends of the legs are connected to one another with a parallel to the central axis extending traverse of the ⁇ -shaped (U-shaped) frame.
- the roller unit is pivotally mounted on the support frame about a steering axis.
- the frame is arranged standing under the support frame, wherein the free ends of the approximately parallel to the steering axis extending legs of the frame facing down and the steering axis perpendicular to both the crossbar, as well as on the central axis. If the motor road roller has two roller units, these are both steerable, with one of the two roller units being able to oscillate in order to compensate for differences in inclination of the ground.
- the steering of a steerable roller unit provides a steering mechanism with an obliquely arranged in the direction of travel between the support frame and the frame hydraulic cylinder.
- DE 37 12 099 A1 discloses a motor road roller with a rigid support frame and with two work elements each designed as a roller. Both rollers are rotatably mounted in ⁇ -shaped (U-shaped) frame about their central axis. Each of the two frames abuts the support frame with its cross-piece connecting the two legs. Both frames are each about its own, perpendicular to both the traverse of the respective frame, as well as on the central axis of the respective, pivotally mounted between the legs of the corresponding frame rotatably mounted roller steering axle.
- DE 2002 00 88 U1 discloses a motor road roller with a rigid support frame and with two working members each designed as a roller.
- Each of the rollers is rotatably mounted in a frame about its central axis.
- the frames are each hingedly connected via an articulated joint with a vertical steering axis with the centrally arranged support frame at its opposite end sides.
- One of the two rollers can be guided relative to the support frame and the remaining roller, or both rollers can be steered in the same direction or in opposite directions with the same or different steering angles.
- the motor road roller can thus also drive obliquely to the orientation of its support frame in the so-called bandage offset, whereby an increase in the width of the roll-formed strip can be obtained.
- the well-known motor road rollers have in common that they allow only a limited width of the hard-rolled strip during operation. In addition, they have a very limited maneuverability, since the steering mechanisms used and / or the articulated connections of the steerable rollers with the support frame allow only a limited inclination of the rollers relative to the support frame.
- An additional disadvantage of the known motor road rollers is their poor drivability along with a limited freedom of movement on paths between sites. It is an object of the invention to increase the work performance in compaction work by increasing the width of the roll-rolled strip by an extension of the roll swivel angle. Another task is to freedom of the road roller and to improve the repair conditions of the roll-rolling system.
- the task is achieved as follows.
- the motor road roller has a rigid support frame, which is supported at the bottom on a pair of preferably at least one roller comprehensive work organs. At least one of these working members thereof is designed as a pivotable about a vertically upstanding on the support frame steering axis pivoting member.
- the pivoting member comprises a U- or ⁇ -shaped frame between the legs at least one roller of a working member is rotatably mounted about a horizontal axis of rotation.
- the traverse of the U- or ⁇ -shaped frame running parallel to the horizontal axis is coupled to the supporting frame by means of a joint with a vertical pivot axis.
- the pivot axis coincides with the steering axis of the respective pivot member.
- the ⁇ -shaped frame is arranged horizontally, so that the traverse is on the outside.
- the crossbar is coupled to a front part of the support frame.
- This front part can be installed so that it is displaceable with respect to the central part of the support frame in the direction of travel of the road roller back and forth.
- the effect of the proposed development can be appreciably enhanced if at least one working member includes a pair of dissimilar rolls.
- a first roller of a pair of dissimilar rollers as a rotatably mounted about its central axis roller in the form of a lying, for example hollow and optionally, for example, with a liquid or a free-flowing substance, such as sand, fillable circular cylinder, which may be made for example of metal, be formed.
- a second roller of a pair of dissimilar rollers may be formed as a plurality of wheels rotatably mounted on a common wheel axle, for example those made of solid rubber.
- Such dissimilar rolls may be united by means of a pair of side beams into a carriage similar to a bogie.
- a middle part of such side bars may be coupled by means of a joint provided with a horizontal axis with the side bars, for example, embracing ⁇ -shaped frame. If the frame surrounds the side beams, the side beams are arranged between the legs of the frame.
- the ⁇ -shaped frame is in turn coupled to the front part of the support frame.
- the carriage is pivotally mounted about the horizontal axis of the joint. This can serve to compensate for unevenness in the ground, with both rollers of a pair of unequal rollers mounted on the carriage keeping in contact with the ground.
- the carriage may be pivotally mounted driven about the horizontal axis of the joint.
- one of the two unequal rollers or both can come into contact with the ground either by actively pivoting about the horizontal axis per carriage.
- This can be advantageous, for example, if the motor road roller moves from one location to another site itself.
- one of the unequal rollers of two carriages provided on a motor road roller is designed as a plurality of solid rubber wheels or the like mounted on a common wheel axle, the driving behavior and concomitantly the freedom of movement of the motor roller on paths between the places of use in comparison with the prior art be significantly improved.
- Both working bodies can also be pivoted about their own, mutually parallel exhaust steering axes.
- a steering mechanism of a pivoting member preferably comprises two hydraulic cylinders.
- the two hydraulic cylinders are arranged in opposite directions obliquely to a longitudinal axis of the support frame of the motor vehicle roller.
- each hydraulic cylinder depending on a first end about a parallel to the steering axis extending hinge axis is pivotally connected to the support frame.
- a respective second end of the two hydraulic cylinders is connected to the frame, for example to its crossbeam, about a joint axis running parallel to the steering axis.
- the two hydraulic cylinders are connected with their second ends on the steering axis opposite sides of the frame with this articulated.
- a steering angle of 90 ° or more ensures that at least one of the two hydraulic cylinders causes a return movement of the pivoting member in its initial position, in which the traverse is orthogonal to the longitudinal axis of the support frame of the motor road roller.
- the steering mechanism thus allows a steering angle of a steerable pivoting member by up to 90 ° in both directions relative to the longitudinal axis of the support frame and thus in a motor road roller with two steerable pivoting members a drive transversely to the longitudinal axis of the support frame eiher obtainedd with a considerable increase in the width of the roll bar.
- the steering angle can be limited to an angle ⁇ 90 ° in both directions.
- At least one pivoting element may be equipped with two identical or different rollers, which prevents a lateral tilting of the motor road roller.
- a significantly improved maneuverability of the motor road roller is also obtained.

The frame 1 is supported at the bottom by a pair of working members in the form of smooth rollers 4 and 5. One of the working members is designed as a pivotable about a steering axis on the support frame 1 arranged pivot member.
- the pivoting member comprises the pivotable roller 4, which is rotatably mounted about a horizontal axis of rotation 6 is coupled to a ⁇ -shaped frame 7 which is arranged horizontally.
- the frame 7 In the case of a horizontal arrangement of the frame 7, its legs and a crosspiece connecting the two legs extend in a plane parallel to the longitudinal axis 16 of the support frame 1.
- the frame 7 is connected to the end of the support frame 1 by means of a steering mechanism.
- the steering mechanism comprises a joint consisting of a bush 8 and a pivot axis 9 forming a steering axis.
- the support frame 1 is rigid with a vertical pivot axis 9. coupled.
- the pivot axis 9 is outside the horizontal projection of the working member or its roller.
- Fig. 2 One of the possible embodiments of the rotary actuator is shown in Fig. 2.
- the power-driven pivotal movement of the ⁇ -shaped frame 7 takes place in the joint by means of a hydraulic cylinder 10, both of which are pivotally connected to the frame 7 and the component of the support frame 1.
- the tilt angle of the roller can reach 90 degrees. This is evidenced by the fact that the point "A" of the rod holder of the hydraulic cylinder 10 is displaced on the ⁇ -shaped frame 7 to the point "B".
- the axis of rotation 6 of the roller 4 and its pivot axis 9 are mounted crossing on the road roller, and their geometric axes are perpendicular to each other.
- Fig. 4 shows the schematic representation of the road roller with two pivot rollers in plan view. In this position, the swung out rollers double the width of the rolled strip. Their swing angle is much less than 90 degrees.

- a roller 1 1 is pneumatic.
- a second roller 12 is smooth and shaking.
- These rollers 1 1 and 12 are united to a carriage by means of a pair of side beams 13. These side bars 13 are connected by means of a horizontal joint 14 with the ⁇ -shaped frame 7. The latter is coupled by means of a hinge with a front part of the support frame 1.
- the joint includes a bush 8 and the vertical pivot axis 9.
- Both end parts are designed to be movable relative to the middle part of the support frame 1.
- the back and herverschiebles the end portions of the support frame 1 is ensured by the fact that they are connected to sliding beams 15.

- a hydraulic drive is used.
- the steering mechanism of the working members of the multi-roll machine is identical to the construction of FIG.
- the peculiarity of this road roller is that thanks to the articulation of the side beam 13 with the ⁇ -shaped frame 7 and the ability to change their inclination angle under the action of a special drive (not shown in the drawing), that allows one or the other roller or their combination depending on the material to be compacted comes into contact with the surface to be compacted.
- a special drive not shown in the drawing
- FIG. 6 the plan view of a motor road roller with four rollers is shown schematically.
- the width of the rolled strip can be achieved in this machine not only in that the working members are pivotable by a large angle, but also in that their substructure is additionally enlarged by the end portions of the support frame 1 by means of the movable beams 15 pushed out bar are.
- the function of the motor road roller with the new pivot system of the work organs is shown using the example of the application of the road roller with four rollers. If compaction work is to be performed by means of rolling according to the nature of the material, the operator selects one or the other of the entirety of the rollers by rotating the carriages of each working member about the horizontal joint 14. The required rollers are brought into contact with the surface to be compacted, and the other rollers are posted. At the same time, an optimum roll-in width is selected by deflecting the rolls by the required angle. This is achieved with the aid of the pivot system according to the invention and in that the end parts of the support frame 1 (FIG. 6) are extended. Thereafter, the Einwalzvorgang can be performed according to the functional scheme of FIG. 7.
