Description

Technical Field

[0001] The invention relates to a compacting roller for a soil compacting machine, comprising a roller shell which is rotatable about a roller rotation axis and surrounds an inner space of the roller, and an oscillation / vibration device (oscillation / vibration-anordnung) arranged in the inner space of the roller. Background Art

[0002] A compacting roller for a ground compacting machine is known from JP2004-223313 A. Two oscillation / vibration units of the oscillation / vibration device of the known compacting roller respectively include a first unbalanced mass component of a corresponding unbalanced mass fixedly supported on an oscillation / vibration shaft rotatable around a corresponding oscillation / vibration rotation axis, and include a second unbalanced mass component supported on an outer circumferential surface of the oscillation / vibration shaft so as to be pivotable relative to the corresponding first unbalanced mass component around a corresponding oscillation / vibration rotation axis.

[0003] Depending on the rotation direction of the two unbalanced mass components about the respectively associated oscillating / vibrating rotation axes, in each of the two oscillating / vibrating units, the centers of mass of the two unbalanced mass components are arranged with a phase offset of 180° relative to the corresponding oscillating / vibrating rotation axes, so that for each oscillating / vibrating unit, an unbalanced resultant torque can be obtained according to the difference in the unbalanced moments of the two unbalanced mass components, or they are arranged at the same side relative to the corresponding oscillating / vibrating rotation axes (i.e., arranged in a manner without phase offset with respect to each other), so that an unbalanced resultant torque can be obtained according to the sum of the unbalanced moments of the corresponding unbalanced mass components. In addition, depending on the direction of rotation, the centers of mass of the unbalanced masses of the two swing / vibration units, each including two unbalanced mass components, have an angular offset of 180° with respect to each other or have no phase offset with respect to each other, so that it is possible to switch between vibration operation and swing operation according to the direction. In the case of the vibration operation, the centrifugal forces acting at the centers of mass of the two swing / vibration units are equal in magnitude and oriented in the same way, thereby forming a total centrifugal force that is essentially orthogonal to the axis of rotation of the roller. In the case of the swing operation, the two centrifugal forces formed at the swing / vibration units are equal in magnitude but oriented in opposite directions, so that a combined torque acting tangentially or in a circumferential direction is formed, and the compaction roller is accelerated back and forth periodically around the axis of rotation of the roller.

[0004] The switch between the two operating states is achieved by pivoting the respective second unbalanced mass component in the two swing / oscillation units by an angle of 180° about the associated swing / oscillation rotation axis relative to the respective first unbalanced mass component, so that in each of the two end positions of the second unbalanced mass component the center of mass of the second unbalanced mass component is located on a common radial line with the center of mass of the respectively associated first unbalanced mass component. Summary of the invention

[0005] The object of the present invention is to provide a compacting roller for a soil compacting machine with an oscillation / vibration device, wherein a change in the unbalanced torque occurring when switching between oscillation and vibration operation can be achieved by means of a compact design of the oscillation / vibration unit.

[0006] According to the present invention, the object is achieved by a compacting roller for a ground compacting machine, which comprises a roller shell rotatable about a roller rotation axis and surrounding an inner space of the roller, and a swing / vibration device arranged in the inner space of the roller, wherein the swing / vibration device comprises:

[0007] a first oscillation / vibration unit having at least one first unbalanced mass which can be driven to rotate about a first oscillation / vibration rotation axis, wherein the at least one first unbalanced mass comprises a first unbalanced mass component A1 and a second unbalanced mass component B1 which can be moved about the first oscillation / vibration rotation axis between two end positions relative to the first unbalanced mass component A1, wherein when the at least one first unbalanced mass rotates about the first oscillation / vibration rotation axis in a first rotational direction, the at least one first unbalanced mass second unbalanced mass component B1 is in its first end position, and when the at least one first unbalanced mass rotates about the first oscillation / vibration rotation axis in a second rotational direction opposite to the first rotational direction, the at least one first unbalanced mass second unbalanced mass component B1 is in its second end position, wherein when the at least one first unbalanced mass second unbalanced mass component B1 moves between its first end position and its second end position, the center of mass MB1 of the at least one first unbalanced mass second unbalanced mass component B1 moves about the first oscillation / vibration rotation axis by a predetermined first angle,

[0008] - a second oscillation / vibration unit having at least one second unbalanced mass which can be driven to rotate about a second oscillation / vibration rotation axis, wherein the at least one second unbalanced mass comprises a first unbalanced mass component A2 and a second unbalanced mass component B2 which can be moved about the second oscillation / vibration rotation axis between two end positions relative to the first unbalanced mass component A2, wherein when the at least one second unbalanced mass rotates about the second oscillation / vibration rotation axis in a first rotational direction, the second unbalanced mass component B2 of the at least one second unbalanced mass is in its first end position, and when the at least one second unbalanced mass rotates about the second oscillation / vibration rotation axis in a second rotational direction, the second unbalanced mass component B2 of the at least one second unbalanced mass is in its second end position, wherein when the second unbalanced mass component B2 of the at least one second unbalanced mass moves between its first end position and its second end position, the center of mass MB2 of the second unbalanced mass component B2 of the at least one second unbalanced mass moves about the second oscillation / vibration rotation axis by a preset second angle,

[0009] wherein, when the second unbalanced mass component B1 of the at least one first unbalanced mass is in its first end position and when the second unbalanced mass component B2 of the at least one second unbalanced mass is in its first end position, the center of mass M1 of the at least one first unbalanced mass and the center of mass M2 of the at least one second unbalanced mass have essentially no phase shift with respect to one another, and a first centrifugal force acting in the center of mass M1 of the at least one first unbalanced mass and a second centrifugal force acting in the center of mass M2 of the at least one second unbalanced mass are directed essentially identically to one another and have essentially the same absolute value of the first centrifugal force, wherein, when the second unbalanced mass component B1 of the at least one first unbalanced mass is in its second end position and when the second unbalanced mass component B2 of the at least one second unbalanced mass is in its second end position, the center of mass M1 of the at least one first unbalanced mass and the center of mass M2 of the at least one second unbalanced mass have a phase shift of 180° with respect to one another, and a first centrifugal force acting in the center of mass M1 of the at least one first unbalanced mass and a second centrifugal force acting in the center of mass M2 of the at least one second unbalanced mass are directed essentially oppositely to one another and have essentially the same absolute value of the second centrifugal force.

[0010] According to the present invention, the preset first angle is less than 180° or greater than 180°, and / or the preset second angle is less than 180° or greater than 180°.

[0011] In the compacting roller arrangement according to the invention, a compact design of the respective unbalanced masses is achieved by a transfer angle different from 180°, in particular a transfer angle less than 180°.

[0012] In order to ensure a defined positioning of the centers of mass of two unbalanced masses with a 180° phase offset or no phase offset with respect to each other in different rotational directions by means of such a relatively short displacement path of the respective second unbalanced mass component, it is proposed that, when the second unbalanced mass component B1 of at least one first unbalanced mass is positioned in its second end position, the center of mass MB1 of the second unbalanced mass component B1 of at least one first unbalanced mass and the center of mass MA1 of the first unbalanced mass component A1 of at least one first unbalanced mass do not lie on a common radial line intersecting the first oscillation / vibration rotational axis, and / or, when the second unbalanced mass component B2 of at least one second unbalanced mass is positioned in its second end position, the center of mass MB2 of the second unbalanced mass component B2 of at least one second unbalanced mass and the center of mass MA2 of the first unbalanced mass component A2 of at least one second unbalanced mass do not lie on a common radial line intersecting the second oscillation / vibration rotational axis.

[0013] Here, it can be particularly mentioned that, when the second unbalanced mass component B1 of at least one first unbalanced mass is positioned in its first end position and when the second unbalanced mass component B1 of at least one first unbalanced mass is positioned in its second end position, the center of mass MB1 of the second unbalanced mass component B1 of at least one first unbalanced mass and the center of mass MA1 of the first unbalanced mass component A1 of at least one first unbalanced mass are located on both sides of a radial line intersecting the first oscillation / oscillation rotation axis in the circumferential direction, and / or, when the second unbalanced mass component B2 of at least one second unbalanced mass is positioned in its first end position and when the second unbalanced mass component B2 of at least one second unbalanced mass is positioned in its second end position, the center of mass MB2 of the second unbalanced mass component B2 of at least one second unbalanced mass and the center of mass MA2 of the first unbalanced mass component A2 of at least one second unbalanced mass are located on both sides of a radial line intersecting the second oscillation / oscillation rotation axis in the circumferential direction.

[0014] In order to ensure an appropriate change in the unbalanced torque when transferring the second unbalanced mass component, it is also proposed that when the preset first angle and the preset second angle are less than 180°, the preset first angle is greater than the preset second angle, and, when the preset first angle and the preset second angle are greater than 180°, the preset first angle is less than the preset second angle.

[0015] According to the principle of the present invention, the above-mentioned compact configuration is achieved in the following manner in a design scheme which is also an independent inventive aspect: a first guide track having a surface normal of a guide track oriented radially inward is provided on a first unbalanced mass component A1 of at least one first unbalanced mass, and the first guide track is used to move a second unbalanced mass component B1 of at least one first unbalanced mass, which is supported radially outward on the first guide track, between its first end position and its second end position; and a second guide track having a surface normal of a guide track oriented radially inward is provided on a first unbalanced mass component A2 of at least one second unbalanced mass, and the second guide track is used to move a second unbalanced mass component B2 of at least one second unbalanced mass, which is supported radially outward on the second guide track, between its first end position and its second end position. By supporting the corresponding second unbalanced mass components radially outward on corresponding radially inwardly oriented guide tracks, it becomes possible to shift the second unbalanced mass components or their center of mass relatively far radially outward, so that the second unbalanced mass components with relatively small mass obtain a relatively large unbalanced torque due to the larger radial spacing from the corresponding swing / vibration rotation axis, and thus can produce the required compensation or addition of the individual unbalanced torques of the unbalanced mass components for the switching performance to the desired extent.

[0016] Since the second unbalanced mass component only needs to be moved within a limited angular range of approximately 180° around the respectively associated swing / oscillation rotation axis in order to switch between swing operation and vibration operation, it is also proposed for a compact configuration that the first guide track extends only over a partial circumferential area around the first swing / oscillation rotation axis and the second guide track extends only over a partial circumferential area around the second swing / oscillation rotation axis.

[0017] In order to be able to achieve a switch between different total unbalanced torques to the same extent in both swing / oscillation units in a simple manner, it is also proposed that the radial spacing of the first guide rail from the first swing / oscillation rotation axis substantially corresponds to the radial spacing of the second guide rail from the second swing / oscillation rotation axis.

[0018] In order to cut off the influence of friction caused by centrifugal force as much as possible when moving between different end positions, it is also proposed that the second unbalanced mass component B1 of at least one first unbalanced mass includes at least one first rolling body rolling along the first guide track when moving between the first end position and the second end position, and the second unbalanced mass component B2 of at least one second unbalanced mass includes at least one second rolling body rolling along the second guide track when moving between the first end position and the second end position.

[0019] In order to provide different unbalanced moments, the number of first rolling elements in the two second unbalanced mass components may be different from the number of second rolling elements.

[0020] In order to keep the number of differently designed components as small as possible, all first rolling bodies and all second rolling bodies are designed identically to one another.

[0021] In an advantageous embodiment which allows greater freedom in the switching behavior, the at least one first rolling body can be different from the at least one second rolling body.

[0022] In order to achieve a symmetrical effect of the two swing / vibration units, it is proposed that the first swing / vibration rotation axis and the second swing / vibration rotation axis are arranged essentially parallel to each other and essentially parallel to the roller rotation axis, and / or that the first swing / vibration rotation axis and the second swing / vibration rotation axis have an angular spacing of approximately 180° relative to the roller rotation axis.

[0023] The first unbalanced mass component A1 of at least one first unbalanced mass can be carried on a first swing / vibration shaft that can be driven to rotate around a first swing / vibration rotation axis, and / or the first swing / vibration shaft can provide at least a portion of the first unbalanced mass component A1 of at least one first unbalanced mass, and the first unbalanced mass component A2 of at least one second unbalanced mass can be carried on a second swing / vibration shaft that can be driven to rotate around a second swing / vibration rotation axis, and / or the second swing / vibration shaft can provide at least a portion of the first unbalanced mass component A2 of at least one second unbalanced mass.

[0024] In order to be able to put various swing / vibration units into operation, it is proposed that the swing / vibration device comprises a swing / vibration drive, and at least one first unbalanced mass of a first swing / vibration unit and at least one second unbalanced mass of a second swing / vibration unit can be driven by the swing / vibration drive to rotate in the same direction of rotation and at the same speed.

[0025] In order to be able to provide a sufficiently large mass in the swing / oscillation unit, it is proposed that the first swing / oscillation unit includes two first unbalanced masses which are arranged at a certain distance from each other in the direction of the first swing / oscillation rotation axis and are preferably designed identically to each other, and / or that the second swing / oscillation unit includes two second unbalanced masses which are arranged at a certain distance from each other in the direction of the second swing / oscillation rotation axis and are preferably designed identically to each other.

[0026] In order to achieve a change in the magnitude of the forces acting on the compacting roller when switching between oscillating and vibrating operation, ie when the rotational direction of the unbalanced mass is switched, it is provided that the absolute value of the second centrifugal force is greater than the absolute value of the first centrifugal force.

[0027] This can be achieved, for example, in that the unbalanced moment of the first unbalanced mass component A1 of the at least one first unbalanced mass substantially corresponds to the unbalanced moment of the second unbalanced mass component B2 of the at least one second unbalanced mass, and the unbalanced moment of the first unbalanced mass component A2 of the at least one second unbalanced mass substantially corresponds to the unbalanced moment of the second unbalanced mass component B1 of the at least one first unbalanced mass, wherein the respective unbalanced moments are defined as:

[0028] U=m×r,

[0029] in:

[0030] U is the unbalanced moment of the corresponding unbalanced mass components A1, B1, A2, B2,

[0031] m is the inertial mass of the unbalanced mass component A1, B1, A2, B2 acting in the mass center MA1, MB1, MA2, MB2 of the respective unbalanced mass component A1, B1, A2, B2, and

[0032] r is the radial distance of the center of mass MA1 , MB1 , MA2 , MB2 of the respective unbalanced mass component A1 , B1 , A2 , B2 from the associated oscillating / vibrating axis of rotation.

[0033] Furthermore, in order to achieve a total unbalanced torque to be set accordingly at the two unbalanced masses, in particular taking into account the relatively short displacement paths of the respective second unbalanced mass components between their end positions, it can be proposed that the first unbalanced mass component A1 of at least one first unbalanced mass has a greater unbalanced torque than the first unbalanced mass component A2 of at least one second unbalanced mass, and that the second unbalanced mass component B1 of at least one first unbalanced mass has a smaller unbalanced torque than the second unbalanced mass component B2 of at least one second unbalanced mass.

[0034] The present invention also relates to a ground compacting machine, which comprises at least one compacting roller having the above structure according to the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] exist Figure 1 In the figure, a ground compactor is generally indicated by 10. For example, the ground compactor 10, which can be used to compact asphalt material, soil, gravel or other bound or unbound soil materials, includes a rear vehicle 12 and an operator's cabin 14 carried thereon. A drive unit is arranged on the rear vehicle 12, and a drive wheel 15 arranged on the rear vehicle 12 can be driven by the drive unit to move the ground compactor 10 in a forward direction or a backward direction.

[0043] The front vehicle 18 constructed by means of a frame 16 is pivotably supported on the rear vehicle 12. The soil compacting machine 10 can be steered by pivoting the front vehicle 18 relative to the rear vehicle 12 about an approximately vertical axis. Figure 2 The compaction roller 20 is shown to be carried in a manner rotatable about the roller rotation axis W. The compaction roller 20 itself can be driven to rotate about the roller rotation axis W, or alternatively the compaction roller can be carried on the frame 16 of the front vehicle 18 in a manner substantially freely rotatable about the roller rotation axis B. When performing the compaction process, the compaction roller 20 rolls on the topsoil 26 to be compacted with the outer surface 22 of the roller shell 24 which encloses the roller interior space 23.

[0044] exist Figure 2An oscillating / vibrating device, which is generally designated by 28, is provided in the roller interior 23 of the compacting roller 20 shown in the longitudinal section in FIG. As described in detail below, forces can be applied to the compacting roller 20 or its roller shell 24 by means of the oscillating / vibrating device 28 in order to thereby influence the compaction behavior. In the oscillating operation described below, the forces are oriented substantially orthogonally to the roller rotation axis W and the direction of the forces rotates around the roller rotation axis W, so that the compacting roller 20 is operated in an oscillating operation, in which the forces acting on the compacting roller 20 accelerate the compacting roller 20 periodically upwards and downwards due to the direction of rotation around the roller rotation axis W, and thus correspondingly periodically impact the topsoil 22 to be compacted or squeeze it. In the oscillating operation of the oscillating / vibrating device, the forces applied to the compacting roller 20 act tangentially or in the circumferential direction, so that the roller shell 24 is periodically accelerated back and forth around the roller rotation axis W in the circumferential direction, thereby forming a push-and-pull effect (walk effect) during the compaction operation.

[0045] The swing / vibration device 28 includes two swing / vibration units 30, 32. Each swing / vibration unit 30, 32 can be driven by a swing / drive 34 to rotate around a corresponding swing / vibration rotation axis D1 or D2. The swing / vibration drive 34 can, for example, have a hydraulic motor 36, which drives the two swing / vibration units 30, 32 via a belt drive 38 to rotate around the respectively associated swing / vibration rotation axis D1 or D2 in the same rotation direction and at the same number of revolutions.

[0046] The first swing / vibration device 30 includes a first swing / vibration shaft 40, which is rotatably supported at the two axial end regions thereof, for example, on the supporting plates 42, 44 coupled to the inner circumferential surface of the roller shell 24. Correspondingly, the second swing / vibration unit 32 includes a second swing / vibration shaft 46 rotatably supported on the two supporting plates 42, 44.

[0047] At the first swing / vibration axis 40 of the first swing / vibration unit 30, two first unbalanced masses 50, 50', which are preferably constructed substantially identically to each other, are carried at a certain axial distance from each other. Similarly, at the second swing / vibration axis 46 of the second swing / vibration unit 32, two second unbalanced masses 52, 52', which are preferably constructed substantially identically to each other, are carried at a certain axial distance from each other. Here, for example, the arrangement is such that each of the two swing / vibration units 30, 32 has an unbalanced mass 50, 50' or 52, 52', respectively, in the same axial region, and the same is true for the other of the two swing / vibration units 30, 32. In addition, Figure 2It is clearly shown that the two oscillating / vibrating units 30, 32 are arranged such that their respective oscillating / vibrating rotation axes D1, D2 extend substantially parallel to the roller rotation axis W and also have the same distance from the roller rotation axis. In addition, the two oscillating / vibrating units 30, 32 or their oscillating / vibrating rotation axes D1, D2 have an angular distance of approximately 180° relative to the roller rotation axis W, so that the two oscillating / vibrating rotation axes D1, D2 are diametrically opposed to each other relative to the roller rotation axis W.

[0048] refer to Figure 3 and Figure 4 , the first unbalanced masses 50, 50' or the second unbalanced masses 52, 52' of the two swing / oscillation units 30, 32 are described in detail below, wherein since the design schemes of the corresponding unbalanced masses 50, 50' or 52, 52' are identical to each other as mentioned above, only the first unbalanced mass 50 of the first swing / oscillation unit 30 or the second unbalanced mass 52 of the second swing / oscillation unit 32 are respectively referenced.

[0049] exist Figure 3 The first unbalanced mass 50, shown in an axial view of FIG. 1 , carried on the first oscillating / vibrating shaft 40, comprises a first unbalanced mass component A1 54, which is connected to the first oscillating / vibrating shaft 40 in a rotationally fixed manner, for example by screwing and / or by material bonding. The first unbalanced mass component A1 54 has an unbalanced mass element 56 fixed to the first oscillating / vibrating shaft 40 and a guide rail element 58 fixedly connected to the unbalanced mass element 56. The unbalanced mass element 56 and the guide rail element 58 delimit a receiving space 60 for a second unbalanced mass component B1 62 of the first unbalanced mass 50, which is movable relative to the first unbalanced mass component A1 54 of the first unbalanced mass 50.

[0050] In the illustrated design example, the second unbalanced mass component B1 62 comprises a first rolling body 64 which is substantially cylindrical, i.e. roller-shaped, and which is loaded radially outward by centrifugal force in the rotational state of the first unbalanced mass 50 and is pressed against a first guide track 66 which is arranged on the guide track element 58 and is oriented radially inward. The first guide track 66 oriented radially inward has a substantially constant spacing from the first swing / oscillation rotation axis D1 in the circumferential direction, so that the radially inwardly oriented guide track surface normal N1 of the first guide track 66 is oriented substantially radially inward relative to the first swing / oscillation rotation axis D1. In the axial direction, the receiving space 60 can be closed, for example, by a disk-shaped covering element to prevent the rolling body from axially falling out of the receiving space 60. The covering element thus provides a part of the corresponding first unbalanced mass component A1 54 and contributes to its mass or unbalanced moment.

[0051] The rolling element 64 of the second mass component B1 62 can be moved along the first guide track 66 between two end positions in the receiving space 60 . Figure 3 In the embodiment, the first rolling body 64 is positioned in its second end position, in which it is supported on the unbalanced mass element 56 in the circumferential direction and is positioned close to the unbalanced mass section 68 of the unbalanced mass element 56. Most of the mass of the unbalanced mass element 56 is arranged in the unbalanced mass section 68, so that the second unbalanced mass component B1 62, such as Figure 3 When positioned in its second end position as shown, the center of mass M1 of the first unbalanced mass 50 is positioned substantially above the first pivot / oscillation axis of rotation D1 , so that in this state the centrifugal forces acting during the rotation of the first unbalanced mass 50 are directed substantially upward.

[0052] After moving the second unbalanced mass component B1 62 along the first guide rail 66, the second unbalanced mass component B1 62 enters its Figure 3 In the first end position shown by the dashed line in FIG. 5 , the first rolling body 64 of the second unbalanced mass component B1 62 is supported in the circumferential direction on the support section 70 of the unbalanced mass element 56. Figure 3In the case of the rotational orientation shown in , the mass center M1 of the first unbalanced mass is substantially arranged on the first oscillating / vibrating rotational axis D1. However, due to the fact that the majority of the total mass of the first unbalanced mass 50 is now located in the lower region of the first unbalanced mass 50, the mass center M1 of the first unbalanced mass 50 has a smaller radial distance from the first oscillating / vibrating rotational axis D1, so that the unbalanced moment existing in the state or in the rotational orientation of the first unbalanced mass 50 is smaller than when the second unbalanced mass component B1 62 is in its Figure 1 6 shows the unbalanced moment of the first unbalanced mass 50 in the second end position shown in the upper part. Due to this, the centrifugal force that occurs when the second unbalanced mass component B1 62 is positioned in its second end position is smaller than the centrifugal force in the state in which the second unbalanced mass component B1 62 is in its first end position supported in the circumferential direction by the unbalanced mass segment 68.

[0053] exist Figure 3 It can be seen that, when the second unbalanced mass component B1 62 is positioned in its second end position, the mass center MB1 of the second unbalanced mass component B1 62 of the first unbalanced mass 50 or 50 ′ is 12 and the mass center MA1 M of the first unbalanced mass component A1 54 11 The two axially spaced apart radial lines are offset from each other in the circumferential direction and are therefore not located on a common radial line that intersects the first oscillating / vibrating rotational axis D1. The radial line that intersects the first oscillating / vibrating rotational axis D1 is based on Figure 3 The radial line R visible in the figure and corresponding approximately to the vertical line in the rotational state is shown. 11 and the center of mass MB1 M 12 Located on both sides of the radial line R in the circumferential direction.

[0054] After the second unbalanced mass has been moved into its first end position, the center of mass MA1 M 11 and the centroid MB1M 12 Also located on both sides of the radial line R in the circumferential direction, because the second unbalanced mass component B1 62 or its mass center MB1M when moving between the second end position and the first end position 12 The guide rail 66 is associated with a first oscillating / vibrating rotation axis D1 and moves at an angle W1 of less than 180°. Figure 3In the rotational state shown, in each of the two end positions of the second unbalanced mass component B1 62 of the corresponding first unbalanced mass 50, 50', the center of mass M1 of the unbalanced mass 50 or 50' is located on the radial line R and above the first oscillation / vibration rotation axis D1, but has a different radial spacing from the first oscillation / vibration rotation axis, so that when the second unbalanced mass component B1 62 is positioned in its second end position, the unbalanced moment of the corresponding first unbalanced mass 50 or 50' is greater than when the second unbalanced mass component B1 62 is positioned in its second end position.

[0055] Figure 4 The structure of the second unbalanced mass 52 is shown, which corresponds in principle to the structure of the first unbalanced mass 50. The second unbalanced mass 52 has a first unbalanced mass part A2 72 which is held in a rotationally fixed manner on the second pivot / oscillation axis 46 and which in turn is formed with an unbalanced mass element 74 and a guide rail element 78 which, together with the unbalanced mass element, delimits a receiving space 76. A second guide rail 80 oriented radially inwards is formed on the guide rail element 78, the guide rail surface normal N2 of which is oriented substantially radially inwards on the second pivot / oscillation axis of rotation D2.

[0056] In the accommodation space 76, the second unbalanced mass component B2 82 of the second unbalanced mass 52 is accommodated so as to be movable in the circumferential direction about the second swing / oscillation rotation axis D2 relative to the first unbalanced mass component A2 72. The second unbalanced mass component B2 82 of the second unbalanced mass 52 includes two second rolling bodies 84, 86, which are, for example, identical to each other and also identical to the first rolling body 64 of the second unbalanced mass component B1 62 of the first unbalanced mass 50. The second rolling bodies 84, 86 can be moved in a rolling manner in the accommodation space 76 along the second guide rail 80 in the accommodation space 76. Figure 4 The end position of the second unbalanced mass or second unbalanced mass component B2 82 shown in the lower center and Figure 4 72 of the second unbalanced mass 52, and the second rolling bodies 84, 86 are supported on the unbalanced mass section 88 of the unbalanced mass element 74, and the second rolling bodies 84, 86 are supported in the circumferential direction on the support section 90 of the unbalanced mass element 74 of the first unbalanced mass component A2 72 of the second unbalanced mass 52. In the axial direction, the receiving space 76 can be closed, for example, by a disk-shaped covering element to prevent the rolling bodies from axially falling out of the receiving space 76. The covering element thus provides a part of the respective first unbalanced mass component A2 72 and contributes to its mass or its unbalanced moment.

[0057] When the second rolling elements 84, 86 of the second unbalanced mass component B2 82 of the second unbalanced mass 52 are positioned Figure 4 In the case of the second end position shown below, the center of mass M2 of the second unbalanced mass 52 is Figure 4 In the rotational state shown in , it is substantially located below the second oscillating / vibrating rotational axis D2. Since most of the mass of the second unbalanced mass component 52 is arranged below the second oscillating / vibrating rotational axis D2 and approximately in the same circumferential area, in this state, the second unbalanced mass 52 has a relatively large unbalanced moment, because the center of mass M2 of the second unbalanced mass 52 has a relatively large radial distance from the second oscillating / vibrating rotational axis D2 due to this mass distribution.

[0058] If the second unbalanced mass component B2 82 of the second unbalanced mass 52 is in its Figure 4 In the first end position shown above, the larger part of the mass of the second unbalanced mass 52 is moved upward. This has the effect that, in this state, the center of mass M2 of the second unbalanced mass 52 or 52' ​​is at Figure 4 In the rotational orientation shown in FIG. 8 , the second unbalanced mass component B2 82 is located substantially above the second oscillation / vibration rotational axis D2, but at a smaller radial distance therefrom than when the second unbalanced mass component B2 82 is positioned in the second end position. This means that the centrifugal force acting in the center of mass when the second unbalanced mass component B2 82 is positioned in the first end position is smaller than the centrifugal force when the second unbalanced mass component B2 82 is positioned in the second end position.

[0059] In the case of the respective second unbalanced mass component 52 or 52', the switching behavior is also achieved in that the mass center MB2 of the second unbalanced mass component B2 82 is 1 / 200 m in both end positions. 22 and the mass center MA2M of the first unbalanced mass component A2 72 21 The second unbalanced mass 52 or 52' ​​is offset from one another in the circumferential direction and thus need not be located on a common radial line intersecting the second oscillating / vibrating rotational axis D2, but rather on both sides of a radial line R which corresponds essentially to the vertical direction in the rotational state. This is also achieved in that the second unbalanced mass component B2 82 or its mass center MB2M of the second unbalanced mass 52 or 52' ​​is moved between the two end positions. 22 The displacement around the second oscillating / vibrating rotation axis D2 is by an angle W2 of less than 180°. In particular, in order to obtain the desired transfer behavior, the angle W2 is smaller than the angle W1.

[0060] It also follows from the above-described construction of the two unbalanced masses 50, 52 that when the corresponding second unbalanced mass component B1 62 or second unbalanced mass component B2 82 is moved between its first end position and its second end position, in the first unbalanced mass 50, the center of mass M1 of the first unbalanced mass 50 is displaced radially, but does not move in the circumferential direction relative to the first unbalanced mass component A1 54, whereas in the second unbalanced mass 52, its center of mass is displaced radially on the one hand and in the circumferential direction by an angle of 180° about the second oscillation / vibration rotation axis D2 on the other hand. This results in that when the two unbalanced masses 50, 52 are relative to each other as Figure 3 and 4 When the respective second unbalanced mass component B1 62 or second unbalanced mass component B2 82 is in its respective second end position, ie supported in the circumferential direction on the unbalanced mass section 68 or 88, respectively, this is Figure 3 and 4 In the view of FIG. 5 , this is the case when the unbalanced masses 50 , 52 rotate in the clockwise direction. The centers of mass of the two unbalanced masses 50 , 52 have an angular offset of 180° with respect to each other, because in the first unbalanced mass 50 , the center of mass is essentially located above the first swing / oscillation rotation axis D1 , while in the second unbalanced mass 52 , the center of mass is essentially located below the second swing / oscillation rotation axis D2 .

[0061] In order to ensure that the respectively acting unbalanced moments of the two unbalanced masses 50, 52 are identical, i.e., the centrifugal forces acting at the respective centers of mass or represented thereby have the same absolute values, the unbalanced mass section 68 in the first unbalanced mass component A1 54 of the first unbalanced mass 50 is designed with a larger volume and thus a larger mass than the unbalanced mass section 88 of the first unbalanced mass component A2 72 of the second unbalanced mass 52. This compensates for the fact that the second unbalanced mass component B2 82 of the second unbalanced mass 52 has twice the mass of the second unbalanced mass component B1 62 of the first unbalanced mass 50.

[0062] If, in the two unbalanced masses 50, 52, the second unbalanced mass component B1 62 or the second unbalanced mass component B2 82 is supported on the support section 70 or 90 of the first unbalanced mass component A1 54 or the first unbalanced mass component A2 72, respectively, this is not necessary when the unbalanced masses 50, 52 are in the Figure 4In the counterclockwise rotation in the view of FIG, the center of mass is located above the oscillating / vibrating rotation axis D1, D2 in each of the two unbalanced masses 50, 52. Due to the mass distribution in this state, the center of mass in each unbalanced mass 50, 52 has a small radial distance from the corresponding oscillating / vibrating rotation axis D1, D2, so that the centrifugal force acting on the corresponding center of mass or represented by it becomes smaller during rotational operation, but the two centrifugal forces acting on the unbalanced masses 50, 52 are oriented in the same direction.

[0063] In the following, reference Figure 5 and Figure 6 The effects resulting from the previously described switching behavior of the unbalanced masses 50 , 50 ′ and 52 , 52 ′ of the two oscillating / vibrating units 30 , 32 of the oscillating / vibrating device 28 during operation of the compacting roller 20 or the soil compacting machine 10 are described.

[0064] Figure 5 The compacting roller 20 is shown in the oscillating operation of the oscillating / vibrating device 28. The two oscillating / vibrating units 30, 32 surround Figure 5 The respectively associated swing / oscillation rotation axis D1 or D2 in the view rotates clockwise and at the same speed. The second unbalanced mass component B1 62 or the second unbalanced mass component B2 82 of the unbalanced mass 50, 50', 52, 52' is in its respective second end position, so that the rolling bodies 64 or 84, 86 are supported in the circumferential direction on the corresponding unbalanced mass segment 68 or 88, or are driven by the unbalanced segment to move in the circumferential direction. The rolling bodies 64 or 84, 86 are supported radially outward on the first guide track 66 or the second guide track 80. Figure 5In the rotational state shown, the center of mass M1 of the first unbalanced mass 50, 50' is located in the height direction above the first oscillation / oscillation rotation axis D1, so that the centrifugal force F1 occurring at the first unbalanced mass 50, 50' is oriented substantially vertically upward. In the second unbalanced mass 52, 52', the center of mass is located vertically or in the height direction below the second oscillation / oscillation rotation axis D2, so that the centrifugal force F2 formed at the second unbalanced mass 52, 52' is oriented substantially vertically downward. Due to the masses provided for the respective first unbalanced mass component A1 54 or first unbalanced mass component A2 72 on the one hand and the respective second unbalanced mass component B1 62 or second unbalanced mass component B2 82 on the other hand and thus also the unbalanced moments present in the respective first unbalanced mass component A1 54, first unbalanced mass component A2 72, second unbalanced mass component B1 62 and second unbalanced mass component B2 82, the oppositely oriented centrifugal forces F1, F2 have the same absolute value. As a result, a torque is generated that acts about the roller rotation axis W, which changes its direction periodically during the rotation of the two oscillating / vibrating units 30, 32, so that the compacting roller 20 or its roller shell 24 is accelerated back and forth periodically in the circumferential direction about the roller rotation axis W. The compacting roller 20 or the oscillating / vibrating device 28 is therefore operated in oscillating mode.

[0065] exist Figure 6 In the figure, two swing / vibration units 30, 32 are shown in a rotated state, in which the two swing / vibration units 30, 32 are rotated in a rotated state. Figure 5 The swing / vibration units 30, 32 rotate counterclockwise at the same rotation speed.

[0066] In from Figure 5 The rotation state to Figure 6 In the transition from the rotational state of the first guide track 66 or the second guide track 80, the second unbalanced mass component B1 62 or the second unbalanced mass component B2 82 is moved in the circumferential direction relative to the corresponding first unbalanced mass component A1 54 or the first unbalanced mass component A2 72 in the corresponding accommodation space 60 or 76 by rolling movement of the rolling bodies 64 or 84, 86 along the first guide track 66 or the second guide track 80, so that they reach the corresponding first end position. In the state, the second unbalanced mass component B1 62 or the second unbalanced mass component B2 82 is supported in the circumferential direction at the corresponding support section 70 or 90, and is driven by the support section to move in the circumferential direction.

[0067] In each of the two unbalanced masses 50, 50', 52, 52', Figure 6 In the rotational state shown, the center of mass is located above the corresponding oscillating / vibrating rotation axis D1, D2, but is Figure 5Compared with the oscillating operation shown in FIG. , the centrifugal forces F1 'and F2 'acting at the center of mass of the unbalanced masses 50, 50 ', 52, 52 'are now oriented in the same direction, i.e., without a phase shift with respect to each other, but with a smaller radial distance from the oscillating / vibrating rotation axis than in FIG. Figure 5 The smaller absolute value of the centrifugal force during the oscillating operation shown in .

[0068] In the swing / vibration units 30, 32 Figure 6 In the rotational state shown in FIG, the two centrifugal forces F1', F2' add up to a total centrifugal force which is oriented radially with respect to the roller rotation axis W. The compacting roller 20 or the oscillating / vibrating device 28 is therefore operated in a vibrating mode in which, during the rotation of the oscillating / vibrating unit 30, 32, the total centrifugal force thus formed rotates about the roller rotation axis W due to the centrifugal forces F1', F2' added in each rotational position, and the compacting roller 20 is periodically accelerated upwards and downwards and accordingly periodically exerts a force on the topsoil 26 to be compacted.

[0069] When switching between oscillating operation and vibrating operation as described above, it is ensured due to the mass distribution in the two oscillating / vibrating units 30, 32 or the first unbalanced masses 50, 50' and the second unbalanced masses 52, 52' that the centrifugal forces F1, F2 or F1', F2' acting at the respective centers of mass have the same absolute centrifugal force values, whereas in oscillating operation the centrifugal forces are directed in opposite directions to one another, which is achieved in that the unbalanced masses 50, 50' or their respective centers of mass have a phase shift of approximately 180° relative to the second unbalanced masses 52, 52' or their respective centers of mass, whereas in Figure 6 In the vibration operation shown, the centrifugal forces F1', F2' acting on the oscillating / vibrating units 30, 32 have smaller absolute centrifugal force values, but are oriented in the same direction as one another, which is achieved in that, due to the mass distribution in the corresponding unbalanced masses 50, 50', 52, 52', the centers of mass of the two oscillating / vibrating units 30, 32 are not phase-shifted with respect to one another.

[0070] To achieve this, not only the two second unbalanced mass components B1 62, second unbalanced mass components B2 82 differ from each other in terms of their mass and thus provide different unbalanced moments, but also the first unbalanced mass components A1 54, first unbalanced mass components A2 72 differ from each other in terms of their mass and thus provide different unbalanced moments. In addition, the first unbalanced mass section A1 54 of each first unbalanced mass 50, 50' substantially corresponds to the unbalanced moment of the corresponding second unbalanced mass component 82' of the second unbalanced mass 52, 52' with respect to the unbalanced moment provided thereby. Similarly, the first unbalanced mass component A2 72' of the second unbalanced mass 52, 52' substantially corresponds to the unbalanced moment of the corresponding second unbalanced mass component B1 62 of the first unbalanced mass 50, 50' with respect to the unbalanced moment provided thereby.

[0071] By switching between oscillating mode and oscillating mode, each with a different absolute value of the centrifugal force, it is also achieved that in oscillating mode, a periodic movement of the compacting roller 20 with a smaller absolute value of the centrifugal force is formed than in oscillating mode. This provides the possibility that the bearings supporting the oscillating / oscillating shafts 40, 46 can be operated at a higher speed and thus at a higher frequency in oscillating mode than in oscillating mode without an excessively strong load increase. Since the degree of change in the absolute value of the centrifugal force can be preset in a wide range of values ​​when switching from oscillating mode to oscillating mode by correspondingly selecting the mass or mass distribution of the unbalanced mass components 54, 62 or 72, 82 and the radial position of the guide rails 66, 80, the change in the speed and thus the frequency achieved by the switching behavior, at which the compacting roller 20 is periodically acted upon by the speed and frequency, can also be preset freely in a wide range of values.

[0072] Finally, it should be pointed out that the above-described structure can of course be varied in various aspects without departing from the functional and structural principles. Thus, for example, only one unbalanced mass or more than two unbalanced masses can be provided in each swing / oscillation unit. However, it should be provided that the same unbalanced torque exists in each swing / oscillation unit. The corresponding second unbalanced mass components can also be designed differently. Therefore, the second rolling body provided in the second unbalanced mass can have a different size or a different shape than the first rolling body provided in the corresponding first unbalanced mass. For example, the different masses of the corresponding second unbalanced mass components can also be achieved in the following way, that is, the rolling bodies of basically the same design size have different masses. For example, in the first unbalanced mass, the first rolling body to provide a low mass can be constructed as a hollow body, and the second rolling body that can be provided in the corresponding second unbalanced mass can be constructed as a solid body, and thus the rolling body that provides a larger mass can be constructed.

[0073] Compared to the design shown in the figure and described above, as long as the center of mass M of the two unbalanced mass components 54, 62 in the first swing / vibration unit 30 or its unbalanced mass 50, 50' is 11 、M 12 and Figure 3 Compared to the arrangement shown in FIG. 5 , the position thereof is swapped relative to the radial line R so that the mass center MA1 M of the first unbalanced mass component A1 54 11 In the illustrated rotational state, the center of mass MB1 of the second unbalanced mass component B1 62 is located to the right of the substantially vertically extending radial line R and in both end positions. 12 The structure or mass distribution of the different unbalanced masses can be changed by being located to the left of the radial line R. In this case, the mass center MB1 of the second unbalanced mass component B1 62 is moved between the two end positions. 12 Move at an angle W1 greater than 180°.

[0074] Alternatively or additionally, it can be provided that in the second wobble / oscillation unit 32 or its unbalanced mass 52 , 52 ′, the mass center M of the two unbalanced mass components 72 , 82 is 21 、M 22 and Figure 4 The arrangement shown in FIG. 7 is interchanged in terms of its position relative to the radial line R so that the mass center MA2 M of the first unbalanced mass component A2 72 21 In the illustrated rotational state, the second unbalanced mass component B2 82 is located to the left of a substantially vertically extending radial line R and at the center of mass MB2 M 22In the two end positions of the second unbalanced mass component B2 82, the center of mass MB2 M is located to the right of the radial line R. In this case, when moving between the two end positions, the center of mass MB2 M of the second unbalanced mass component B2 82 22 Move at an angle W2 greater than 180°.

[0075] If both angles W1 , W2 are greater than 180°, the angle W2 is greater than the angle W1 in order to achieve a suitable switching behavior with regard to the unbalanced torque to be set.

[0076] In principle, designs are also conceivable in which one of the angles W1 , W2 is smaller than 180° and the other angle is larger than 180°, or in which one of the angles W1 , W2 is exactly 180°.
