Definitions

• the present invention relates to a link chain for a KegelIMOnumschlingungsge- transmission, with a plurality of hingedly interconnected via pressure pieces link plates which are arranged transversely to the longitudinal direction of the link chain behind the other and in the longitudinal direction of the link chain offset from one another and overlapping sections and the link chain a plurality of two has in the longitudinal direction of the link chain differently long link plates with openings for receiving the plungers.
• a link chain of the type mentioned here is composed of a plurality of link plates and pressure pieces, wherein the plungers are also referred to as pins or pins and are known under the name of cradles.
• the link plates for forming such a link chain are thereby selected from two types of link plates, namely a so-called short link plate and a so-called long link plate.
• the plate chain thus formed is used to transfer tensile force between two conical disk pairs of a conical pulley belt transmission.
• the power transmission between the conical disk pairs and the link chain takes place friction-based.
• the reference numeral 10 designates in the longitudinal direction of the link chain considered short link plates, while designated by the reference numeral 22 in the longitudinal direction of the link chain considered long link plates.
• the reference numeral 12 designates in the schematic view selected in Fig. 1 of the drawing a bolt, but in fact it is the center of a pressure piece pair of two pressure pieces 14, 16, as shown in Fig. 2 of the drawing.
• T TK denotes a short division
• T L denotes a long division
• the pitch T is the distance between the centers of two adjacent bolts 12 and two pressure piece pairs 14, 16.
• the wear behavior of the pressure pads has an influence on the service life of the conical disk belt drive, so that a reduction of the flank wear of the pressure pads contributes to an extension of the service life.
• the present invention is based on the object to provide a link chain, which shows an improved wear behavior.
• the invention now provides for the solution of this problem, a plate chain for a conical-Scheibenumsschlingungsgetriebe, with a plurality of hingedly interconnected via pressure pieces link plates which are arranged transversely to the longitudinal direction of the link chain behind the other and in the longitudinal direction of the link chain offset from each other and each other in sections Ü overlapping and the link chain a plurality of two in the longitudinal direction of the link chain differently long link plates with openings for receiving the Plungers has, the arrangement of the link plates in the longitudinal direction of the link chain is provided such that a short link plate follows a long link plate.
• the provided according to the invention plate chain is therefore composed of a variety of pressure pieces and link plates together.
• two different types of link plates are provided, namely a short link plate considered in the longitudinal direction of the link plate chain to be formed and a chain link which is long in this longitudinal direction and which therefore differ with regard to their longitudinal extent.
• extensions may be provided on individual link plates, which are provided so that these extensions overlap staggered link plates and thus avoid a lateral displacement of the link plates, ie in the transverse direction of the link chain.
• the effective pitch length is the distance between two adjacent pressure piece pairs, ie distance T according to the in Fig. 1 of the drawing.
• Fig. 1 of the drawing shows the known link chain, in which follows a large effective pitch TL a large effective pitch TL. Such an arrangement is excluded in the tab chain according to the present invention.
• a short link plate Due to the order of education that follows a long link plate a short link plate, can follow a short link plate another short link plate or a long link plate, the effective pitch length between two adjacent pairs of pressure pieces to a short effective pitch length and a so-called mean effective pitch length reduced.
• the case of the short effective pitch length is when a short link plate is followed by a short link plate and the case of the mean effective pitch length is when a long link plate is followed by a short link plate or a long link plate is followed by a long link plate.
• Fig. 1 is a plan view of a schematic representation of a known link chain in three-lashing association
• FIG. 2 shows a side view of a link plate for explaining individual terms
• FIG. 4 shows a side view of a section of a link chain according to an embodiment according to the present invention.
• Fig. 5 is a diagram for comparing the flank wear on a known link chain and a link chain according to the present invention.
• Fig. 3 of the drawing shows a side view of a section of a known link chain.
• K and L in the area below the link chain 1, the length of individual members of the link chain 1 is designated.
• K therefore denotes a short link of the link chain 1, ie a link with short link plates, while L denotes a long link link.
• L denotes a long link link.
• a long member L on a follow long link L so that there is a large or long effective division between two adjacent pressure piece pairs.
• the effective pitch is given in Fig. 3 of the drawing above the link chain 1 with K, M and L.
• K corresponds to the effective division between two adjacent short chain links, followed by a short chain link, a long chain link, it turns between the two adjacent pairs of pressure elements a division medium length M, and follows a long chain link turn a long chain link, it turns between the two adjacent pair of pressure piece a long pitch L a. It has now been found that the flank wear of the pressure pieces in the region of the long pitch L is higher than in the region of the division of medium length M and in the region of the division short length K.
• FIG. 4 Drawing now shows in direct comparison the order of formation of a link chain 2 according to an embodiment of the present invention.
• a chain link of long length L is always followed by a chain link of short length K, while a chain link of short length K can be followed by another chain link of short length K or a chain link of long length L.
• This order of formation now leads to the effective division (inscription K, M above the link chain 2) between two adjacent pressure piece pairs always corresponds to a short effective pitch K or a mean effective pitch M, but never to a long effective pitch L.
• Fig. 5 of the drawing shows a diagram of the flank wear of the known link chain 1 compared to the link chain 2 according to the present invention.
• the link chain 2 according to the invention is particularly suitable for use in a conical-pulley transmission, which is intended for use in the field of commercial vehicles.
