Definitions
- the present invention relates to a link chain for a continuously variable transmission (CVT) with conical disk pairs whose links are made of links which are interconnected by means of joints forming rocker joints whose end faces transmit the frictional forces between the link chain and the conical disks, wherein at least one the tabs, preferably each of the tabs, has at least one overlap tab and the tab chain has a chain pattern in Dreilaschenv, in which three consecutive chain links have different tab arrangements of tab units with at least one tab transverse to the direction of the tab chain and repeat in the longitudinal direction of the tab chain , The arrangement of the tabs in the dressing across the chain width has a great influence on the strength and the life of the chain.
- the chains are built in the so-called Dreilaschen notion with triples, d. H.
- the arrangement of the tabs repeats all three members and without consideration of the tab types.
- different long strap types are used, which produce unevenly long links, in order to minimize or to denature the noise, which results from the impact of the rocker plates on the conical disks.
- WO 2008/071 145 A1 shows various link chains for continuously variable bevel gear transmissions whose links having chain links are connected to each other by rockers having rocker-type joints, wherein the end faces of these joints transmit the friction forces between the link chain and the conical disks.
- the link chain on a chain pattern in Dreilaschenv in which three consecutive chain links -a so-called triple-differ- Laschenan extracten of tab units each having at least one tab transversely to the direction of the link chain and repeat in the longitudinal direction of the link chain.
- the tabs of some of these link chains have overlap tabs, so are zip tabs.
- In other of the tab chains shown is On luff tabs having tabs, so zip pockets, have been completely eliminated.
- the object of the invention is to further reduce the maximum loads on the tabs and the pressing pieces during operation so as to provide a chain with a longer service life.
- the link chain for continuously variable conical disc gear whose links chain links are connected by Wiegedschreib joinede joints having their faces transmit the frictional forces between the link chain and the conical disks, at least one of the tabs, preferably more of the tabs, in particular each of the tabs, at least one Has luff and the link chain has a chain pattern in Dreilaschen said, in which three consecutive chain links different
- Laschenan extract of tab units each having at least one tab transverse to the direction of the link chain and repeat in the longitudinal direction of the link chain is provided according to the invention that the tab units comprises first tab units and second tab units, each of the first tab units is formed as a single tab of a defined thickness and each of the second tab units has a significantly greater strength than the first one
- Tab assembly are first tab units, and (iii) the third of the chain members has only second tab units. Investigations have shown that strap straps constructed in this way have a higher strength and a longer service life compared with known link chains with other chain patterns in the three-strap association.
- the overlap tabs are used in the treated in the context of the invention plate chains in Dreilaschenv particular to prevent jamming of individual tabs with each other. Further details on tabs with overlapping lobes (ie, tab lobes) and on the function of tab tabs in tab chains can be found, for example, in the document WO 2008/071 145 A1 mentioned in the introduction.
- the second of the chain links has either only first tab units or both first tab units and at least one second tab unit, wherein only the outer tab units of the tab arrangement are first tab units, ie the other tab unit or the other tab units, that is is not arranged outside, second
- Lashing units are. According to a preferred embodiment of the invention it is provided that the thickness of the second plate unit is twice the thickness of the first plate unit.
- the structure according to the invention regardless of the number of tabs or tab units in the respective tab arrangement transversely to the direction, that is independent of the chain width, ensures relatively low loads on the tabs and Wiegedschreib Swisse in operation. This has proven to be particularly important for relatively narrow link chains but also for relatively wide link chains, since there is a particular need for a reduction in the maximum loads of tabs and Wiegedschreib Swissen in operation. Accordingly, it is advantageously provided that the first of the chain links has either six or fewer (ie two, four or six) or ten or more (ie ten, twelve, fourteen,...) First lug units. According to a further preferred embodiment of the invention, the second tab unit is designed as a double tab formed from two tabs.
- Such a link chain has, in a number of advantageous embodiments, a chain pattern in the three-lobe association, in which three consecutive segments the (triple) have different tab assemblies with single and double tabs transverse to the direction of the chain and repeat in the longitudinal direction of the chain.
- the invention provides a specific arrangement of the individual lugs to double lugs, wherein member 1 (the first of the chain links) only of individual lugs.
- Link 2 (the second of the chain links) consists of single and / or double straps, the outer straps being single straps and the remaining straps being double straps.
- Link 3 (the third of the links) consists only of double links.
- the second tab unit is formed as a single thick tab (thick plate) with higher strength, in particular with double thickness, as the single tab of the defined thickness.
- the mentioned double straps can be implemented by individual double-thickness thick plates.
- the thick plates can also have a different thickness to twice the thickness.
- the double lug can be replaced in the middle of the chain by a single leash, so that the chains can be built more flexible in their width.
- This triple structure is independent of the tab types, ie whether long tabs, short tabs are used and regardless of the pitch of the tabs. Therefore, the length of the tabs in the individual chain links is different. In particular, two different lengths tabs, ie a shorter tab and a longer tab compared to this shorter tab are provided. Since the tabs or at least a part of these tabs has overlap tabs, there are possibilities for the triple structure of a triple, which would lead to a waiver of the use of tabs with overlap tabs to a functional restriction. So it is through the use of tabs with overlapping lobes in the
- Dreilaschen possible, two longer tabs to follow each other directly, which would not be possible in a waiver of the use of tabs with luffing tab.
- the chain links of different lengths are advantageously arranged unevenly in the chain running direction.
- the chain can be constructed of blocks with six tabs each with two tabs per link or triple.
- the block is in turn symmetrical and consists of three tabs. With the help of these blocks can be displayed in different widths tabs in the manner of a modular construction.
- a chain consists of at least one block.
- the number of tabs for each member may be the same, with preferably the number of tabs in the member being divisible by two.
