Description

System for axis adjustment, eccentric element for such a system and method for axis adjustment

The present invention relates to a system for adjusting the axis, an eccentric element for such a system and a method for adjusting the axis.

Axle adjustments of commercial vehicles are known from the prior art.

In particular, the track of an axle or the track of the wheels fixed on the axle is set or corrected by means of an axle adjustment. In the case of axle adjustments known from the prior art, a spindle or a threaded rod is used in particular, which is rotated relative to an engaging element and thus triggers a shortening or lengthening of the adjusting element, which in turn shifts along the longitudinal axis of the vehicle at one end of the axis Commercial vehicle caused. The problem here is that the spindle is susceptible to contamination, corrosion or damage from parts whirled up while driving and that the setting of the spindle is time-consuming, in particular due to a large number of necessary assembly steps, and thus the operational safety of the commercial vehicle can only be guaranteed with great effort can be.

US-A-2011/0068524 and EP 2736732 B1 disclose an axis adjustment for an axle of commercial vehicles with a frame element, an Exzenterele element and a link element, the eccentric element having a first contour or a first opening via which a link element with the eccentric element can be brought into engagement and wherein the eccentric element has a second contour or has an outer contour via which the frame element can be brought into engagement with the Exzen terelement. The first contour is arranged eccentrically to the second con ture and the eccentric element can be non-positively fixed to the frame element and the link element via a first fastening means, and the frame element and the link element are secured in a vobestimmable position along an adjustment direction by setting a certain angle of rotation of the eccentric element and are pivotable against each other.

It is the object of the present invention to provide a system that improves or simplifies the measures for enabling comfortable track setting or axle adjustment, in particular with regard to the structural measures required for this on the vehicle frame.

This object is achieved by a system according to claim 1, an eccentric element according to claim 14 and a method according to claim 15.

According to a first aspect of the present invention, a system for adjusting the axis of an axle, in particular a commercial vehicle, is provided, comprising a frame element with a first guide area, in particular in the form of a first guide opening, for moving a link element on which the axle is mounted State is connected, in the adjustment direction, an alignable eccentric element with an opening, the arrangement of which determines the displacement of the link element based on the first Füh approximately area, and a second Füh approximately area, in particular in the form of a second guide opening, via which the eccentric element and the frame element with each other Are engaged and a pin-like element engages in the assembled state, the pin-like element being displaceable or movable when aligning the eccentric element relative to or along the second guide area, in particular in the second guide opening. It is provided according to the invention that a pin-like element engages in a second guide area, in particular to secure the eccentric element against displacements in the adjustment direction. Correspondingly replaces the combination of the second guide area and the pin-like one Element the fastening tabs or tab elements, which are known from the prior art, in order to secure the eccentric element against displacements or displacements in the adjustment direction. In this way, weight can advantageously be saved on the entire system for adjusting the axis of an axis. In addition, the system for axis adjustment is designed to be as economical as possible in terms of installation space, in particular in comparison to the systems for axis adjustment from the prior art. Finally, the use of a system according to the invention enables more creative freedom in the design of a system for mounting axles, since the lateral delimitation by the strap elements can be dispensed with. In particular, it is provided that the system is used for axis adjustment for alignment, ie for aligning a link element with respect to the direction of travel of a vehicle on which the link element is mounted. For example, a steering element is one that carries the axle at one end, for example in a corresponding bearing, and is articulated at the other end on the frame element, for example on a bracket. The pivotable mounting of the link element on the bracket is used in particular together with an air spring system for the resilient mounting of the axle. A bracket has before geous enough on two side walls, which are ver connected to each other via an end wall. The two side walls have in particular the first guide area or areas. A bearing block within the meaning of the invention is in particular a bearing block for a utility vehicle and is therefore advantageously able to support an axle load of 7 t, preferably 10 t, and particularly preferably 12 t. The bearing block advantageously has an assembly plane which is used to be connected to a frame of a vehicle, in particular by means of an integral joining. Advantageously, the Monta geebene by surfaces of the two side walls and / or the end wall ausgebil det. By means of the system for axis adjustment, the possibility is ensured of setting the link element correspondingly at an angle, in particular in relation to a direction predetermined by the direction of travel. It is conceivable that the pin-like element is formed on the frame element and / or on the eccentric element ment or the second guide area is formed on the eccentric element and / or on the frame element. Accordingly, it is provided that the pin-like element and the second guide area engage in one another in the assembled state and in particular contribute to the binding of the eccentric element to the frame element. The pin-like element can be, for example, a cylinder pin, a taper pin, a dowel pin and / or a bolt with or without a head and with or without a thread. The pin-like element is advantageously designed in such a way that it extends in a longitudinal direction and has a diameter which is smaller than the maximum extent in the longitudinal direction. The first guide opening is preferably a, preferably straight, elongated hole which is formed essentially parallel to the adjustment direction. It is also conceivable that the elongated hole runs at least in sections at an angle to the adjustment direction. Furthermore, it is preferably provided that the first guide area formed as an elongated hole is formed on two opposite side walls of the frame element in order to enable a clear shift or inclination of the axis with the shift along the first guide area. In particular, it is provided that the eccentric element is aligned when it is aligned, ie in particular when it is rotated to displace the axis, so that the opening of the eccentric element is arranged congruently above a certain section or sub-area of the elongated hole of the first guide area. By means of a fastening means extending through the opening and through the first guide area, it is then possible to fix the eccentric element and thus fix the position of the axle, in particular when the link element itself is articulated. Particularly preferred, the position of the bearing element is coupled to the alignment of the Exzen terelements, for example by the link element has an opening that is permanently congruent with the opening in the eccentric element in the assembled state. The system is preferably provided for a utility vehicle or a utility vehicle trailer. A utility vehicle trailer or utility vehicle is in particular a vehicle or a trailer which has a permissible total mass of at least 7.51 t, preferably of at least 10.1 t and particularly preferably of at least 15.1 t. Furthermore, the pin-like element is preferably part of the frame element, the pin-like element particularly preferably being arranged at the same level as the first guide area. In addition to the design of the first guide area and / or the second guide area in the form of an elongated hole, it is alternatively also conceivable that the first and / or the second guide area is designed in the form of a rail system, in which a pin-like element in a corresponding rail-like recess or a corresponding device intervenes. The design as a continuous guide opening has proven to be particularly advantageous in production and handling, in particular because tilting or the like is not to be expected here.

According to a preferred embodiment, the second guide area runs gen-shaped or curved, preferably as an arcuate elongated hole. Particularly preferably, the second guide area, in particular designed as a second guide opening, runs with a constant radius of curvature and / or concentrically to the center of the eccentric element. The arcuate course extends preferably over more than 45 °, for example the arcuate second guide area extends over an angular range between 45 ° and 180 °. Furthermore, it is preferably provided that a ratio of a radially dimensioned distance between tween the arcuate second guide area and the outer contour on the one hand to the eccentricity, ie the distance between the first center point of the opening of the eccentric element and the second center of the eccentric element, on the other hand Assumes a value between 0.5 and 0.9. Correspondingly, the second guide area is at the outermost edge of the eccentric element. It is preferred that the elongated hole is formed without a contour or without a profile. Alternatively, it is conceivable that the elongated hole, in particular on its inside, which is in contact with the pin-like element, is profiled or has a contour in order to continuously define certain positions for the pin-like element. For example, it is conceivable that the inside of the contour, which defines the second guide area or the second guide opening, is shaped like a wave, so as to be in to define the valleys preferred orientation of the pin-like element in the second guide opening. In this way, discrete values can be defined for the axis adjustment.

The second guide area advantageously runs in the shape of a circular arc or a circular arc segment, the circular arc having a guide center point and a guide radius. “Running in the shape of a circular arc” is to be understood as meaning that the extent of the second guide region corresponds to or follows an arc segment of a circular arc. The guide radius corresponds in particular to the radius or the diameter of the circular arc or the circular arc segment of the second guide area. The guide center point is the center point of the circle to which the second guide area corresponds at least in segments in its extension. As a result, a particularly simple production can be achieved. The second guide area is therefore advantageously designed as a circular arc-shaped elongated hole or as a circular arc segment-shaped elongated hole, the circular arc having a guide center which can advantageously be congruent with the center point of the outer contour and / or the second center. A particularly simple production can be achieved in this way.

The system particularly preferably has a reference system for detecting a relative position of the pin-like element within the guide opening. This advantageously makes it possible for the user to be informed of the position of the second opening relative to the first guide area or in relation to the first guide area. This is particularly advantageous because the first guide area is not visible to the user when the eccentric elements are selected accordingly. By means of the reference system, for example in the form of a scaling, it is correspondingly possible to detect a relative position. In addition, it is possible to record any changes in the long term or to document them. It is also possible to coordinate the respective positions with those of other axle bearings in order to ensure optimal adjustment or axle adjustment as quickly as possible, especially on the same vehicle. The eccentric element preferably has the second guide area. The arrangement of the second guide area on the eccentric element makes the second guide area visible to the user. In contrast, in an embodiment in which the pin-like element is embossed on the eccentric element and engages in a corresponding opening in the frame element, this would not be visible. In the case of a corresponding development of an invisible second guide area, however, this would also be protected against pollution and other environmental influences.

The eccentric element can advantageously be displaced manually and / or by a motor. For example, the eccentric element has a flanging aid in the form of a recess, with a crank element being insertable in this recess, if necessary, in order to effect the corresponding displacement, ie. H. to cause the rotation of the eccentric element. However, it is also conceivable that the eccentric element can be shifted via a motorized mechanism. Here, for example, by means of a position of the motor that rotates the eccentric element, conclusions can be drawn about the current position of the eccentric element, in particular with regard to the position of the opening in relation to the first guide area. For example, a toothing is provided on the outermost circumference of the eccentric element in order to absorb a drive movement or rotary movement. However, since the axis is relatively seldom shifted, especially when it comes to the unity of an axis system, it is generally advantageous to dispense with a corresponding motorization, with the associated weight, and instead to shift the eccentric element by means of manual actuation.

Preferably, the first guide area and / or the opening in the Exzen terelement has a first radius and an outer contour of the eccentric element has a second radius, wherein a first center of the first guide area and / or the opening is spaced an eccentricity from the center of the outer contour, wherein a Ratio of (R2 - R1 - E) to R2 in the range between 0.2 and 0.8, is preferably between 0.4 and 0.6, and particularly preferably between 0.45 and 0.55.

Alternatively or additionally preferably, the first guide area in the eccentric element has a first radius (R1), the second circular arc-shaped and / or the circular arc segment-shaped guide area having a guide radius (R3), a first center of the first guide area being around a guide eccentricity (FE ) is at a distance from the guide center, with a ratio of (R3 - R1 - FE) to R3 in the range between 0.2 and 0.8, preferably between 0.4 and 0.6, and particularly preferably between 0.45 and 0, 55 lies. With a ratio of 0.2 to 0.8, a particularly simple production of the eccentric element can be achieved. With a ratio of 0.4 to 0.6, the applicant has surprisingly found that this makes it possible to achieve particularly good adjustability and intuitive operation. With a ratio of 0.45 to 0.55, a particularly good compromise between adjustability and space requirements can be achieved.

The eccentricity and the guide eccentricity are advantageously the same, and / or the guide center point and the second center of the outer contour are congruent. Particularly simple production can be achieved through this.

The opening is expediently a circular opening. In this way, a particularly simple production can also be achieved and a particularly secure and defined reception of a fastening or tensioning means, in particular for a wishbone, can be achieved.

The link element preferably has an engagement area which can be brought into engagement with the first guide area of the Exzenterele element or a fastening means, at least in some areas, in a form-fitting manner. The fastening means is preferably a screw or a bolt that is used to determine the alignment of the eccentric element or the link element through the frame element, the link element and the eccentric element engages and the frame element, the link element and the eccentric element clamped together ver by a corresponding fixation by means of, for example, a nut. The link element can be connected directly and / or indirectly to the eccentric element.

The second guide area is preferably coated at least in certain areas. In particular, the inside of the second guide opening is coated in order to minimize friction between the pin-like element and the second guide area in order to ensure the simplest possible displacement. In addition, it could be useful to harden the corresponding contact surface between the pin-like element and the second guide area, or to provide it with a corresponding coating that reduces wear when using the Exzen terelements.

Particularly preferably, the pin-like element extends through the eccentric element in the assembled state and protrudes with respect to the eccentric element. This advantageously allows the eccentric element to be additionally fixed on the frame element via the stiftar term element. For example, it is conceivable that the pin-like element has a thread at its penetrating end, via which a corresponding counterpart can be screwed in order to fix the eccentric element on the frame element. This advantageously facilitates the fixing of the eccentric element. In particular, it is conceivable that the corresponding protruding portion of the pin-like element is used for a pre-adjustment of the eccentric element and the final fixation takes place only after the pre-adjustment by means of the fastening means that extends through the opening of the eccentric element.

Another aspect of the present invention is an eccentric element for a system for adjusting the axis of an axle, in particular of a utility vehicle, comprising a frame element with a first guide area, in particular in the form of a first guide opening, for moving a link element io to which the axle is connected in the assembled state, in the adjustment direction, an alignable eccentric element with an opening, the arrangement of which determines the displacement of the link element in relation to the first guide area, and a second guide area, in particular in the form of a second guide opening, via which the The eccentric element and the frame element are in engagement with each other and a pin-like element engages in the assembled state, the pin-like element being movable or displaceable when aligning the eccentric element relative to or along the second guide area, in particular in the second guide opening. All the features and advantages described for the system can be transferred analogously to the eccentric element and vice versa.

Another aspect of the present invention is a method for adjusting the axis by means of a system for adjusting the axis of an axle, in particular a commercial vehicle, comprising a frame element with a first guide area, in particular in the form of a first guide opening, for moving a steering element on which the axle is connected in the assembled state, in the adjustment direction, an alignable eccentric element with an opening, the arrangement of which defines the displacement of the link element in relation to the first guide area, and a second guide area, in particular in the form of a second guide opening, via which the eccentric element and the The frame element is engaged and in which a pin-like element engages in the assembled state, the pin-like element being displaceable or movable when aligning the eccentric element relative to or along the second guide area, in particular in the second guide opening.

Fig. 1 shows a side view of a system known from the prior art for axis adjustment. A frame element 2, an eccentric element 4 and a link element 6 are provided as essential components, the link element 6 being connected to the frame element 2 via a fastening means 8, for example a bolt or a screw, and the eccentric element 4. The eccentric element 4 has an outer contour 44 which is designed to be circular, for example, the circular outer contour 44 having a radius R2. Furthermore, the eccentric element 4 has an opening 42 which is also designed to be circular before given and whose center is spaced from the center of the outer contour 44, ie the opening 42 is not to the outer contour 44 arranged concentrically. Correspondingly, the opening 42 is arranged eccentrically to the outer contour 44 of the eccentric element 4. The eccentric element 4 is supported against displacement in the adjustment direction L against two opposing second tab elements 10, which by means of a form-fitting co-operation in the adjustment direction L a displacement of the eccentric element 4 verhin countries. If the eccentric element 4 is now rotated by an angle of rotation a, it moves the opening 42 a displacement in the adjustment direction L, since the eccentric element 4 is supported on the second bracket elements 10 and is thus secured against displacement in the adjustment direction L. Preferably, the link element 6 is indirectly or directly in engagement or connection with the opening 42, wherein when the opening 42 is displaced in the adjustment direction L, the link element 6 also experiences a displacement in the adjustment direction L. Furthermore, the link element 6 is preferably via a first fastening means 8, which in particular produces a frictional connection and / or a form fit between the opening 42 and an engagement area 62 of the link element 6, not shown in FIG. 1, and in this way the link element 6 at the opening 42 specifies. Furthermore, a first guide area 22 of the frame element 2 is shown - shown with a dashed line - which serves in particular to prevent the link element 6 from being displaced transversely to the adjustment direction L. By defining the position of the opening 42 above the first guide region 22, an extent of the displacement of the link element 6 in the adjustment direction L is defined. The first guide area 22 is particularly preferably designed as a first guide opening. Alternatively, it would be conceivable that the first guide area 22 is a first guide rail.

A handling aid 45 is preferably provided on the front of the eccentric element 4, which is designed, for example, as a projection or handle or as a recess for a hand crank, in particular a hand crank that can be inserted into a recess. Using the handling aid 45, it is particularly easy for the user to twist the eccentric element 4 relative to the frame element 2 and thus fix the position of the opening 42 relative to the first guide opening. FIG. 2 shows the sectional view already indicated in FIG. 1 of the preferred embodiment shown in FIG. 1. It can be seen particularly clearly that the fastening means 8 reaches through both the first guide area 22 of the frame element 2 and through the opening 42 of the eccentric element 4 and through the engagement area 62 of the link element 6 and these parts or units, for example, form-fitting and / or frictionally, firmly attached to each other. In this preferred embodiment, the engagement area 62 of the link element 6 and also the opening 42 of the eccentric element 4 are designed as a recess or bore, with a circular or cylindrical geometry in which a cylindrical body, such as a Bolt or screw can engage. The position of the center point of the opening 42 relative to the position of the center point of the outer contour 44 is also shown by means of the broken lines. This position or this offset in the adjustment direction L is denoted by the letter x. In addition, in this embodiment, the tab element 10 is designed in one piece with the frame element 2 as a projection, in particular preferably two tab elements 10 opposite one another in the adjustment direction L are provided, which secure the eccentric element 4 against displacement in both the positive and negative adjustment direction L. . The fastening means 8 is particularly preferably designed as a screw, with a nut being provided opposite the screw head, ie shown on the top side in the figure, which creates a force fit between the elements or units penetrated by the screw. It is particularly preferred that washers not shown in the figure are used to enable pivoting of the link element 6 relative to the frame element 2 even when there is a frictional connection, the washers slide against one another during this process.

In FIGS. 3 and 4, an eccentric element 4 is shown in a perspective view (FIG. 3) and in a top view (see FIG. 4) according to an exemplary embodiment of the present invention. In contrast to the eccentric element 4 from FIGS. 1 and 2, the eccentric element 4 of FIGS. 3 and 4 is next to a second guide region 32 is provided in the opening 42. In the example shown in FIGS. 3 and 4, the second guide area 32 is designed as an arcuate elongated hole, which preferably extends over an angular range between 45 ° and 180 °, particularly preferably between 60 ° and 150 °. In particular, it is provided that the eccentric element 4 is disk-shaped and / or that the second guide region 32 is designed as a second guide opening, the general course of which is preferably concentric to the outer contour 44.

The second guide area 32 serves in particular for mounting the Exzen terelements 4 on the frame element 2. For this purpose, a pin-like element 31 engages in the second guide area 32, in particular in the form of a second guide opening. This advantageously makes it possible to dispense with the tab elements 10 which, in the embodiments according to the prior art, are used to secure the eccentric element 4 against displacement in the positive and negative adjustment direction L. This task is now fulfilled by the second guide area 32 together with the pin-like element 31 which engages in the second guide area 32.

It is particularly preferably provided that the eccentric element 4 has a reference system 30, for example in the form of a scale, on the basis of which the user can determine the position in which the eccentric element 4 is in the installed state. This is particularly advantageous because, given the corresponding dimensioning of the eccentric element 4, the first guide area 22 is covered so that the user does not have a clear view of the first guide area 22. Correspondingly, the reference system 30 serves as an orientation aid in order to determine the extent of the adjustment or the position in the first guide area 22. It is also possible to use the reference system 30 to document changes.

Furthermore, it can be seen from FIGS. 3 and 4 that the handling aid 45 is a recess or a recess in the eccentric element 4, into which a corresponding crank element can be inserted if necessary can in order to simplify the alignment or displacement of the eccentric element 4 during operation.

In the plan view of the eccentric element 4 shown in FIG. 4, the first radius R1 of the opening 42 and the second radius R2 of the outer contour 44 are shown. The first radius and the second radius each run from the first center of the opening 42 and the second center M2 of the eccentric element 4. In particular, it is provided that the first center M1 is offset by an eccentricity E with respect to the second center M2. It has proven to be particularly advantageous if a ratio of (R2 - R1 - E) to R2 is in a range between 0.2 and 0.8 and particularly preferably between 0.4 and 0.6. In the illustrated FIG. 4, care must be taken to ensure that the diameters are drawn in, which are each made up of two radii. In particular, it is provided that the first center M1 is offset from the guide center M3, which can also be referred to as the guide center, by a guide eccentricity FE. The second guide region 32 is designed in FIG. 4 as an elongated hole running in the shape of an arc of a circle, the arc of a circle having a guide center point M3. The circular arc has a guide radius R3.

FIG. 5 shows a frame element 2 for a system 1 for axis adjustment according to a preferred embodiment of the present invention. In particular, the frame element 2 shown is a support bracket which is provided for mounting a link element 6. The pivot element 6, which is pivotably mounted on the support bracket, is preferably mounted about an axis, the position of which is determined by means of the system 1 for axis adjustment. The frame element 2 shown here comprises two side surfaces which run essentially parallel to one another and each have openings 22 in order to mount the steering element 6 on the bracket or frame element. It is preferably provided that only one of the side walls has a first guide area 22 in the form of an elongated hole, while a round opening is provided in the other side surface, which does not allow any displacement in the adjustment direction L, so that a displacement on the first guide area 22 a definite one Determination of the alignment of the axis is determined. In particular, with the system 1 for axis adjustment, an inclined position of the steering element 6 can be implemented in this way, or a corresponding inclined position can be compensated. In particular, it is provided that a pin-like element 31 protrudes from the side surface, in particular the side surface with the first guide area 22 shaped as an elongated hole, which is provided in particular to reach through the second guide area 32 of the eccentric element 4 in the assembled state . In comparison to the embodiments of the system 1 for axis adjustment from the prior art (see FIGS. 1 and 2), the tab elements 10 can advantageously be dispensed with, and instead the comparatively small pin-like element 31 serves as a replacement for the tab elements 10. In this way, weight can also be saved in an advantageous manner.

In FIGS. 6 to 8, the system 1 for axis adjustment with an eccentric element 4 from FIGS. 3 and 4 and a frame element 2 from FIG. 5 is shown in the assembled state. 6 to 8 show the respective alignments of the eccentric element 4. In particular, FIG. 7 shows a central position in which the eccentric element 4 is aligned or is oriented such that the opening 42 of the eccentric element 4, viewed in the adjustment direction L, in a center of the first guide region 22 is arranged. In contrast, the eccentric element 4 is arranged in Figure 6 such that the opening 42 strikes a first end of the first guide area 22, while in Figure 8 the eccentric element 4 is aligned such that the first opening 42 over a second end of the first guide area 22 is arranged. Correspondingly, the second guide area 32, i. H. the arcuate elongated hole, coordinated with the orientation of the opening 42 above the first guide area 22, in particular such that in the position of Figure 6 and Figure 8, the pin-like element 31 comes into contact with the ends of the arcuate elongated hole of the second guide area 32.

Furthermore, it is preferably provided that the pin-like element 31 extends not only through the second guide region 32, but also opposite it the eccentric element 4 protrudes. This advantageously allows the eccentric element 4 to be additionally fixed on the frame element 2 via the pin-like element 31, for example by means of a corresponding nut. In particular, the eccentric element 4 is clamped menelement 2 via the pin-like element 31 on the frame.

In Figure 9, two frame elements 2 are shown according to a second and third embodiment of the present invention. They are characterized in that the pin-like element 31 is formed by reshaping a side wall of the frame element. For example, in the left exemplary embodiment a sleeve-shaped or cylindrical projection is punched out or embossed and in the right-hand side a tab is formed by a bending process in such a way that the tab runs obliquely to the outer wall or side wall of the frame element 2. As a result, the pin-like element 31 can be formed on the frame element 2 in a particularly simple manner.
