Definitions
- the invention relates to a link chain, in particular for a continuously variable transmission of a motor vehicle, with longer and shorter chain links, which comprise coupled by Wiegedruck GmbHcrufare longer and shorter tabs.
- the invention further relates to a CVT transmission with such a link chain.
- the letters CVT stand for the English words Continuously Variable Transmission and mean that the ratio of the CVT transmission is steplessly adjustable.
- a plate chain for a continuously variable transmission of a motor vehicle which consists of individual chain links which are interconnected by hinge means, each of these chain links has a plurality of substantially mutually parallel tabs, wherein at least a part of the chain links has different tabs with at least a first tab type and at least one second tab type.
- a link chain with a plurality of pressure pieces articulated link plates is known, wherein the pressure pieces are transverse to the longitudinal direction of the chain, wherein a deflection of the
- Lashing chain is resistive in at least one direction transversely to its direction of travel for damping pressure oscillations.
- German Laid-Open Specification DE 101 18 102 A1 discloses a link chain with at least one swiveling safety device, which ensures that the swiveling angle between chain links with different pitches is less than 27 degrees. From the German patent application DE 197 43 676 A1 further the use of tabs is known, which have two openings which are separated from each other by means of a central web.
- the object of the invention is to further improve a link chain according to the preamble of claim 1, in particular with regard to their life and / or an undesirable noise during operation.
- the problem is solved with a link chain, in particular for a continuously variable transmission of a motor vehicle, with longer and shorter chain links, coupled by Wiegedruck Swisspare longer and shorter tabs, achieved in that the longer tabs each have two openings which are separated by a central web ,
- the link chain preferably comprises a plurality of tabs which are transverse to a chain running direction are arranged side by side in series.
- the construction and the function of such a link chain are disclosed, for example, in the German Offenlegungsschriften mentioned above.
- tests on conventional link chains have found that the mass distribution over the chain longitudinal direction is not optimal. In particular, it has been found during the investigations that the specific mass at the longer chain links is lower than at the shorter chain links.
- a preferred embodiment of the link chain is characterized in that the shorter tabs each have an opening.
- the shorter straps which are also referred to as short straps
- the attachment of central webs has not been found to be advantageous, since due to the small space due to production only relatively thin central webs could be realized. Therefore, the shorter tabs of the invention
- Lashing chain only one common opening for two pairs of rocker push pieces.
- a further preferred embodiment of the link chain is characterized in that a central region of the opening in the shorter lugs is curved inwards in a circular arc.
- the common opening in the shorter tabs in the middle has a smaller extent transverse to the longitudinal direction of the chain than in the receiving areas for the rocker pressure pair. This has proved to be advantageous in the operation of the link chain according to the invention, both in terms of the strength of the shorter tabs and in terms of acoustics.
- a further preferred embodiment of the link chain is characterized in that the central region of the opening in the shorter lugs on opposite sides is curved in a circular arc inwardly.
- the opening in the shorter tabs gets essentially the shape of a waisted slot.
- Another preferred embodiment of the link chain is characterized in that the link chain only shorter tabs, each having an opening, and longer tabs, each having two openings, which are separated by a central web.
- a further preferred embodiment of the link chain is characterized in that all shorter tabs of the link chain are made equal. As a result, the production costs for the plate-link chain according to the invention can be considerably reduced.
- Another preferred embodiment of the link chain is characterized in that all the longer tabs of the link chain are made equal. As a result, the production costs for the plate-link chain according to the invention can be further reduced.
- a further preferred embodiment of the link chain is characterized in that the central web in the middle of the link in the chain longitudinal direction has approximately the same extent as the two openings in the longer link. This has proved to be advantageous in terms of strength and mass distribution.
- the invention further relates to a shorter tab and / or a longer tab for a previously described tab chain.
- the tabs are separately tradable.
- the invention further relates to a CVT transmission with a previously described
- Link chain In the CVT transmission, the link chain serves to drively connect two sets of conical disks together.
- Figure 1 is a longer tab of a tab chain according to the invention in plan view and Figure 2 is a shorter tab of the plate chain according to the invention also in plan view.
- a longer tab 1 and a shorter tab 21 are each shown in plan view.
- the longer tab 1 is also called a long flap.
- the shorter tab 21 is also referred to as a short flap.
- the link chain according to the invention comprises only two types of tabs, specifically the elongated tabs 1 shown in FIG. 1 and the short tabs 21 shown in FIG. 2. All the elongate tabs 1 have the same design. All short flaps 21 are made equal.
- the plate-link chain according to the invention is carried out in a similar or similar way to the tab-type chain described in German Offenlegungsschrift DE 100 47 979 A1.
- the plate-link chain according to the invention is used in a continuously variable conical-pulley transmission, as likewise disclosed in the cited patent application.
- the longer tab 1 shown in FIG. 1 comprises a left tab side bar 2 and a right tab side bar 3.
- the tab side bars 2 and 3 are integrally connected to one another at the top by an upper strap bracket 4. Below are the two
- Tab side brackets 2 and 3 integrally connected by a lower strap bracket 5.
- the longer tab or elongated tab 1 comprises an opening 8 and an opening 9.
- the two openings 8 and 9 are separated from one another by a central web 10.
- a double arrow 6 is indicated in Figure 1 that the central web 10 in the chain longitudinal direction, which corresponds to the horizontal direction in Figures 1 and 2, the same extent as the opening 8 and the opening 9 has.
- the two openings 8 and 9 have the same extension in the chain longitudinal direction.
- the weighing pressure piece pair 1 1 arranged in the opening 8 comprises two weighing pressed pieces 13 and 14.
- the weighing piece piece 12 arranged in the opening 9 comprises two weighing pieces 15 and 16.
- the long flap 1 is filled in the middle with material.
- the central area has been optimized with the central web 10.
- the shorter flap or short flap 21 shown in FIG. 2 comprises a left-hand flap
- Tab side brackets 22 and 23 are integrally connected at the top by an upper strap bracket 24. Below the two tab side bars 22 and 23 are integrally connected by a lower strap bracket 25.
- the short flap 21 shown in FIG. 2 comprises only one common opening 30 for two pairs of weighing pieces 31 and 32.
- the weighing piece 31 comprises two weighing pieces 33 and 34.
- the weighing piece 32 comprises two weighing pieces 35 and 36.
- the opening 30 is provided in a central region 37 with bends 38 and 39.
- the curvature 38 has substantially the shape of a circular arc, which is convexly formed on the upper bracket strap 24.
- the curvature 39 also has the shape of a circular arc, which is convex on the lower bracket 25.
- the opening 30 in the middle between the two rocker pressure piece pairs 31 and 32 has a smaller extension transversely to the chain longitudinal direction, ie in the vertical direction in FIG. 2, than in the receiving areas for the rocker pressure piece pairs 31 and 32 ,
