DE2357880A1 - Coupling piece vehicle tyre chain - has a W-shape whose outer arms have curved recesses on their inner lower sides - Google Patents

Abstract

The recesses in the arms together with the central limb of the coupling form a reception basin which encircles the horizontal element of the chain by more than 180 deg. and preferably 270 deg. The arms have a thickness at the base of the recess approx. equal to the thickness of the base of the coupling between the side and central arms. Following insertion of the chain elements, the side arms are bent towards the central arm which process is facilitated by the weakened areas near the recesses. The tops of the arms have inward facing stop surfaces which rest against the central arm when the coupling has been completed. The use of the recessed design ensures a secure connection between chain links.

is in the form of a stud with a central protrusion and lateral protrusions, the latter for formation of eyelets for the legs of horizontal links of a chain network after the horizontal links have been attached into those formed by two projections each Forks are bent in the direction of the central protrusion,

In the case of the insert or connection part after the parent application v / ground the protrusions formed by teeth that have essentially the same cross-section over their entire length. As a result, there are difficulties prepares the eyelets for the legs of the horizontal links of a chain network to be suspended to give, which offers the guarantee for a perfect guidance of the horizontal links in the eyelets with little wear. The invention is based on the object of creating an insert or connecting part of the type in question, of which Eyes ensure good guidance of the horizontal members while being easy to manufacture. This object is achieved according to the invention solved in that the lateral projections in the area of the eyelets to be formed have recesses which together with the parts of the stud connecting the central projection with the lateral projections, one of the legs of the horizontal members form a trough surrounding more than 180 °.

The insert or connecting part according to the invention offers the advantage that it can be easily installed on the one hand and that, on the other hand, due to the selected trough-shaped design of the base of the fork formed by the cracks, a low-wear and safe guidance of the horizontal members in the eyelets is guaranteed.

In a preferred embodiment, the recesses are arcuate and form substantially plate-shaped troughs. ".-, -.: .. '. · _;

The wrap angle with which the trough-the legs ■ the enclosing horizontal members to be suspended should if possible be large and preferably be about 2.70 °.

To make it easier to bend the outer protrusions it is useful * to weaken the studs in the area of the recesses.

The invention is described below with reference to one in the appended Drawing illustrated embodiment explained in more detail. Show it;

Fig. 1 is a side view of a connecting part according to the invention, in which two horizontal members are suspended;

Fig. 2 is a side view of the insert or connecting part . in Fig. 1, viewed in the direction of arrow II and

Fig. 3; the side view of an insert part that is in a Horizontal link is used.

In Figs. 1 and 2, 11 is generally a connector denotes that of a continuous tunnel 12 with a central projection 13 and two lateral projections 14 formed will. With the connecting part 11: are two horizontal members 15 and 16 connected.

When the connecting part 11 is assembled with the horizontal members 15 and 16, the projections 14 take the form shown in FIG the shape shown on the left, which makes it possible to hang the horizontal link. After the horizontal member is shown Has taken position, the one assigned to him will be assigned

lateral projection 14 bent in the direction of the central projection 13 until the one in FIG. 1 on the right Page position shown is reached, in which the projections 13 and 14 extend substantially parallel to each other.

As Fig. 1 shows, the lateral front $> Runge 14 in the area of the eyelets to be formed for the horizontal members provided with arcuate recesses 17, which together with the central projection 13 with the lateral projections 14 connecting parts of the cleat 12 a substantially part-circular, the legs of the horizontal members 15, 16 form a trough surrounding almost 270 °. The legs of the horizontal links can be in the troughs move with a certain amount of play. line risk of getting stuck will not exist. By matching the diameter of the trough to the diameter of the for making the Horizontal members 15, 16 adjusts the wire used, can be good leadership relationships between the horizontal members and the connecting part.

In order to facilitate the bending over of the lateral projections, the height h .. of the cleat 12 is in the region of the base of the trough substantially equal to the height hp of the lateral front jumps 14 at the weakened point of the lateral protrusions 14.

The selected design of the trough bottom and the lateral projections 14 ensures that the legs the horizontal members are well encompassed and properly guided in the connecting part.

If one wants to define the bending angle of the lateral projections 14, it proves to be advantageous if the lateral projections are provided with stops 18,

which are shown in Fig. 1 in dashed lines. It understands that these attacks must be shaped so that they the insertion of the horizontal members 15 and 16 in the of the lateral projections 14 and the central projection 13 limited fork does not interfere.

Fig. 3 shows an insert part 19, which consists of a cleat 20 with a central projection 21 and two lateral ones Projections 22 is made. The insert 19 is carried by a horizontal member 23.

The insert 19 is in the area of the lateral projections provided with recesses 24, which together with the central projection 21 and these with the lateral projections 22 connecting parts of the cleat 20 form a trough * which ensures limited mobility between the insert 19 and the horizontal member 23. These Mobility is for the chain of self-cleaning great importance. The stops 25 hold the lateral projections 22 in the desired position *
