Definitions
- the present invention relates to a toothed link chain comprising lug sets of toothed plates as well as at least one guide lug, which is arranged within the lug packet or as a lateral end flap on two chain pins.
- guide straps are required. These can be designed as inner (simple) or outer (double) guide. Most outer guide tabs are used because this additional processing of the gear, namely the introduction of an annular groove at the point where the guide tab is to engage in the gear omitted.
- the chain guide in the outer guide is achieved by an overlap of the guide plates with the sprocket end face (wheel tooth).
- the guide lug is another lug in the existing toothed lug package.
- a toothed link chain with a guide tab according to the independent claims.
- the problem is solved in particular by a toothed link chain comprising lug sets comprising toothed plates and at least one guide lug which is arranged within the lug packet or as a lateral end lug on two chain pins, wherein the guide lug has a wing which a lashing tooth of a toothed lug in the same lug packet in the direction or opposite the running direction of the toothed plate chain projects beyond.
- the wing reaches the guide tab of a toothed wheel before the front tooth of the toothed link seen in the chain running direction. It is thus causes a leading leadership of each individual tooth.
- the guide lug has two wings each projecting beyond a lug tooth of a toothed lug in the same lug set in the running direction and / or against the running direction of the toothed lug chain.
- toothed link chains which are operated with alternating direction, so the advantages of leading-ahead leadership of the wing according to the invention can be used for both directions. Between the wings remains a constriction in the form of a material-free space, so that over a continuous wing, the advantage of a material savings remains.
- the wings have a bevel on their side facing a wing of an adjacent guide lug, which leaves a gap to a corresponding slope of the adjacent guide lug upon buckling of the adjacent guide lug.
- the wings have a bevel on their side facing a wing of an adjacent guide lug, which at least partially closes a gap to a corresponding slope of the adjacent guide lug on buckling of the adjacent guide lug. If the gap is almost completely closed, an optimal leading guidance is achieved because a maximum allowable overlap of the wing with the associated tooth of the gear is achieved without touching two adjacent wings of two adjacent guide plates.
- the wings have a rounding on their side facing a wing of an adjacent guide lug, which leaves a gap to a corresponding rounding of the adjacent guide lug upon buckling of the adjacent guide lug.
- the rounding can be positioned at an optimal location with respect to the overlap with the tooth of a gear on buckling of the chain.
- the guide plate has a waist between the attachments to the chain pin.
- the waist has a height which is smaller than the height of the toothed plates. This allows a particularly pronounced shape of the sidecut.
- toothed plate chain can also be provided that this further comprises lug sets of toothless mating tabs, wherein the tab sets of toothed plates and the tab sets of counter tabs are arranged alternately in the chain running direction.
- a guide lug for a toothed lug chain according to the invention with the features directed onto the guide lug, as well as a transmission and a vehicle, in particular a motor vehicle, with a toothed lug chain according to the invention.

- FIG. 11 shows a detail of an elongated plate chain with guide straps according to FIG. 10;
- FIG. 12 shows a section of a curved link chain with guide straps according to FIG. 10.
- Fig. 1 shows an example of a side view
- Fig. 2 is a plan view of a plate chain according to the prior art with Zweilaschenv.
- the link chain 1 comprises a plurality of tabs 2 and counter tabs 3.
- the tabs 2 and counter tabs 3 are each arranged alternately and connected to hinge pin 4 as a hinge.
- Both ends of a tab are thus connected by means of a joint with one or two counter-tabs, correspondingly both ends of a counter-tab are connected by means of a hinge with one or two tabs.
- the hinge pin 4 may be in one piece, but are preferably in two parts, wherein a rocker 5 is associated with each of the tabs and unrolls on one of the mating tab 2 associated rocking piece 6.
- the rocker pieces 5, 6 each have a rolling profile 7 or T with which they can roll or slide on one another.
- the rolling profiles 7, T may be identical or different.
- tabs 2 and counter-tabs 3 are identical components in the present embodiment, a distinction between tabs 2 and 3 counter-tabs recognizable only by the arrangement. Therefore, only tabs 2 are discussed below, since they are identical to the counter-tabs except for the packet-wise arrangement.
- Fig. 2 a stack of three tabs 2 and two opposing tabs 3 is shown, but here also stack with any other number of tabs 2 and 3 counter-tabs can be provided.
- the tabs 2 are - as can be seen in Fig. 1 - each provided with tab teeth 9.
- the link chain 1 with a toothing, z. B. a gear, comb.
- the division between tabs 2 and counter-tabs 3 is designed so that a uniform division between the tab teeth 9 results in a stretched chain.
- the counter-plates 3 may additionally be provided with tab teeth 9, so that all tabs and counter-tabs are each provided with tab teeth 9.
- Fig. 3 shows a first embodiment of a guide plate 10 according to the invention.
- the guide plate 10 comprises two holes 11 and 12, with which it can be attached to the chain pin 4.
- the holes 11 and 12 are designed so that they each correspond to the rocker 5.6, to which the belonging to the respective chain link 8, 8 'lug set is attached.
- the guide plate 10 has a wing 13.
- the wing 13 is arranged on the guide plate 10 that this is in the installed position of the guide plate 10 within the link chain 1 on the same side of the link chain 1 as the tab teeth 9.
- the wing 13 protrudes beyond a base body 14 which is substantially symmetrical to a Symmetryeachse 15 is arranged out.
- the guide plate 10 has a thickness e.
- the guide plate 10 has a thickness of d, wherein the thickness d is smaller than the thickness e.
- the guide plate 10 is thus fitted between the holes 11, 12 and there has a Tille 17. If one places in the region of the holes 11, 12 on the upper side, ie the side facing away from the wing 13, the guide plate 10 is an enveloping straight line 16 and parallel to this on the underside, ie the side on which the wing 13 is arranged, a straight line 16a, which contacts the guide plate in the region of the thickness e, the wing 13 protrudes beyond this pair of straight lines 16, 16a enveloping the base body 14.
- the main body 14 is both in the region of the sidecut 17 and in the region of the two holes 11 and 12 a circular outer contour with radii R1, wherein the radii R1 are identical.
- Fig. 5 shows a section of a link chain 1 with guide plates 10 according to the invention.
- the tooth plates 2 have a minimum thickness D in the region between the plate teeth 9 or between the pins 4.
- the minimum d of the guide plates 10 in this area is less than the minimum Thickness D of the toothed plates 2.
- FIGS. 8 and 9 show an alternative embodiment of a guide plate 10.
- a guide plate 10 In contrast to the embodiments in Figs. 3 to 6 here instead of a wing 13, a front wing 13a and a rear wing 13b are present. Otherwise, the embodiment of Fig. 7 substantially corresponds to the embodiment of Fig. 3.
- the wings 13 a and 13 b in contrast to the embodiment of FIG. 3 on the outer sides of the wings each have slopes 19 a and 19 b. The slopes are designed as straight lines.
- the function of the bevels 19a, 19b is apparent from the illustration of FIGS. 8 and 9.
- the stretched chain 1, in Fig. 9 is shown, the bent or curved chain 1 when looping a gear 18.
- FIGS. 10 to 12 show a further embodiment of a guide tab 10 according to the invention.
- the exemplary embodiment is substantially similar to that of FIGS. 7 to 9, in which
- the bevels 19 a and 19 b are formed here as curves 20 a and 20 b.
- the embodiment of FIGS. 10 to 12 is shown without waist 17, but this can also be present in this embodiment.
