Device for attaching a crawler track member of a crawler track to a crawler belt of the crawler track

Abstract

A device for attaching a crawler track member of a crawler track to a crawler belt of the crawler track having a press-in element and a connection element, wherein the press-in element comprises a main body having a continuous opening, wherein when the press-in element is arranged on the crawler belt, the connection element for connecting the crawler track member to the crawler belt engages through the continuous opening. The device is characterized in that the press-in element comprises multiple holding elements projecting from the main body, wherein the holding elements are configured in such a manner that when they are arranged on the crawler belt they penetrate multiple material layers of the crawler belt, in that the holding elements displace material of the material layers, in particular transversely to the penetration direction.

(3) FIG. 2 shows a perspective view at an oblique angle from the side from above of a further variant of the device;

(4) FIG. 3 shows a perspective view at an oblique angle from the side from below of the press-in element of the device according to FIG. 2;

(5) FIG. 4 shows a sectional view through the crawler belt of a device according to FIG. 2 arranged on the crawler belt; and

(6) FIG. 5 shows a perspective view of devices according to FIG. 2 arranged on the crawler belt.

DETAILED DESCRIPTION OF THE INVENTION

(7) FIG. 1 shows a first variant of a device 1 according to the present invention comprising a press-in element 2 and a counter element 3.

(8) For the sake of transparency, the same reference numbers are used below for different embodiments of a device and, in particular, of a press-in element. The individual variants described below can be advantageously flexibly combined with a further variant which is different thereto.

(9) The counter element 3 is, for example, configured as a washer with a centrally disposed through-hole, for example. The press-in element 2 comprises a main body 4, holding elements 5, a sealing member 6. For example, the main body comprises in addition a positioning member 7.

(10) The main body 4 is advantageously configured in a disc-like or plate-like manner and has a first main side 8 and a second main side 9 which are opposite and spaced apart from one another. The first and the second main side 8, 9 advantageously form main planes of extent of the main body 4. The main body 4 moreover comprises a continuous opening 10. On the second main side 9, the positioning member 7 projects from the second main side 9, for example.

(11) The holding elements 5 project from the first main side 8 of the main body 4. The holding elements 5 have a conical or truncated conical design, for example. The holding elements 5 are spaced apart from one another along a circular arc, for example, on the first main side 8 of the main body 4. The circular arc has a circle center which, for example, coincides with an axis of symmetry, e.g. an axis of rotation of the main body 4.

(12) The sealing member 6 is advantageously bead-like in design. The sealing member 6 encloses an edge of the opening 10 of the main body on the first main side 8 in a completely circumferential manner. The sealing member 6 is raised from a main plane of extent of the first main surface 8. An inner region 11 of the sealing member 6 has a sleeve-like, e.g. hollow cylindrical, configuration, for example. For example, the inner region 11 of the sealing member 6 forms part of the opening 10 of the main body 4. A wall thickness of a hollow cylindrical sealing member 6 is, for example, between 1 mm and 5 mm, e.g. 2 mm. A transition 12 of the inner region 11 of the sealing member 6 to the main plane of extent of the first main surface 8 is rounded off, for example. In this way, when the device 1 is arranged on a crawler track, an abutment of the device 1 on the crawler belt and therefore a seal to prevent the penetration of water into the crawler belt is improved.

(13) A further device 13 with a further variant of a press-in element 2 is depicted in FIGS. 2, 3.

(14) FIG. 4 shows a crawler track 19. On the crawler track 19, the device 13 is present in an arranged state on a crawler belt 14, wherein by means of the device a crawler track member in the form of a crawler web 15 is attached to the crawler belt 14. The press-in element 2 in this case is connected to the crawler web 15 by means of a connection element in the form of a screw 16. In the sectional view of the crawler web 15 shown in FIG. 4, there are multiple fabric layers 17 of the crawler belt 14, which are embedded in an elastic material 18 of the crawler belt 14.

(15) The holding elements 5 are advantageously configured in such a manner that in the arranged state of the press-in element 2 on the crawler belt 14 the holding elements 5 penetrate a fabric structure of the fabric layers 17, so that the holding elements 5 penetrate the fabric structure and advantageously compress or displace the fabric structure of the fabric layers transversely to the penetration direction E in this case. In this way, a severing of the fabric layers is preferably avoided, as a result of which a weakening of the crawler belt 14 is advantageously reduced. A comparatively strong anchoring of the press-in element 2 with the crawler belt 14 is also thereby effected.

(16) As depicted in FIG. 5, multiple, in particular three, devices 13 are advantageously arranged on the crawler belt 14, in order to attach a crawler track member (not shown in FIG. 5) to the crawler belt 14.
