Definitions

  • the present invention relates to a link chain for a conical pulley, with a plurality of hingedly articulated 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 side by side and overlapping sections and the link plates have openings that are penetrated by the pressure pieces.
  • condition caused by the link chain acoustic load of the driver of a motor vehicle is to be considered, in which a cone pulley wound with the plate chain is used.
  • the entry of the rocker pressure pieces into the gap between the conical pulley pairs results in a shock pulse, which causes structure-borne sound excitation.
  • the structure-borne sound formed thereby can continue into the interior of the motor vehicle and be perceived as disturbing there.
  • the present invention is based on the object to improve the above-described generic link chain in acoustic and strength-related terms. Also, the running behavior of the lashing chain to be created is to be improved with respect to the friction occurring during running.
  • the invention now provides to solve this problem, a link chain with the features of claim 1.
  • the invention created by the lashing chain can also have the features of claims 2, 3, 4 or 5.
  • the link chain according to the invention is characterized by a very specific arrangement of their link plates.
  • the invention provides a plate chain for a conical-pulley, with a plurality of hingedly articulated 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 side by side and overlapping sections and the link plates have openings that from the Thrust pieces are interspersed, and the plate chain has twenty-seven juxtaposed longitudinal rows and the assignment to the longitudinal rows following pattern:
  • A is the arrangement of the link plates in a first transverse row of a longitudinally repeating arrangement of three transverse rows of the link chain
  • B is the arrangement of the link plates in a second transverse row of a longitudinally repeating array of three transverse rows of the link chain
  • C is the arrangement of link plates in a third transverse row of a repeating in three transverse rows of the link chain longitudinally repeating arrangement.
  • the invention provides a link chain with a triple bond, in which therefore viewed in the longitudinal direction of the link chain of the above reproduced structure regularly repeats.
  • the link chain according to the invention has single lugs or double lugs, wherein adjacent double lugs are separated from each other by at least one leash. If a given load of the tab chain thus formed is assumed, which is present, for example, in the converter approach point of a motor vehicle with a conical disk wrap transmission, then a tab chain with the setup model reproduced above has proved to be advantageous.
  • the link chain may also have the following structure:
  • A corresponds to the arrangement of the link plates in a first transverse row of a repeating three transverse rows of the link chain longitudinally repeating arrangement
  • B is the arrangement of the link plates in a second transverse row of a repeating three transverse rows of the link chain longitudinally repeating arrangement
  • C of the arrangement the link plates is in a third transverse row of a repeating after three transverse rows of the link chain in the longitudinal direction arrangement.
  • this link chain has lower converter loads in the Kettenlaschen by tensile force and lower bending stresses of the rocker than on the Wandleranfahrddling at the given load spectrum in the known link chain is the case. Also, both above-described with respect to the repetitive structure in the longitudinal direction of the link chain chain chains are acoustically advantageous, since they reduce the excitation of the thus formed Kegelusionnumschlingungsgetriebes to form structure-borne noise.
  • Fig. 1 is a plan view of the structural construction of a link chain according to the present invention.
  • Fig. 2 is a similar view showing the structural structure of the link chain according to an alternative embodiment

  • Fig. 5 is an illustration showing the structure of a link chain according to another alternative embodiment of the present invention.
  • FIG. 1 of the drawing shows in the upper illustration the structure of the link chain according to the invention in a first transverse row A and the construction of the link chain in a second transverse row B and a third transverse row C, each partially overlapping each other and with horizontally extending lines 101, 102, 103, 104 marked the location of not shown in detail rocker pressure pieces in each illustrated dressing.
  • the structural structure is repeated after every three transverse rows, ie a respective triple connected.
  • the tab chain of the invention has twenty-seven longitudinal rows of link plates which are juxtaposed and partially overlapping one another.
  • the Laschen said shown has single lugs and double lugs, ie directly adjacent to double lugs composite link plates, but not directly adjacent to each other double lugs and is constructed point-symmetrical.
  • the strap assembly shown in FIG. 1 has the best response to a given load collective at the transducer approach point, that is to say the best evaluation collective of tensile force in the link plates and bending stresses in the rocker pressure pieces.
  • Fig. 2 of the drawing shows a triple bond of the plate-link chain according to the invention according to an alternative embodiment.
  • link plates in the transverse rows A, B, C viewed in the longitudinal direction of the triple band, are arranged differently, for example, the link plate in the longitudinal row 12 of the embodiment according to FIG. 2 of the drawing is arranged in the transverse row A, while FIG it is arranged in the embodiment of FIG. 1 of the drawing in the middle transverse row B.
  • triple bond has formed to the plate chain adjacent to each other in the longitudinal direction a better load behavior than the known link chain, ie lower tensile forces in the link plates and lower compressive stresses in the rocker pressure pieces.
  • the triple linkage shown in Fig. 3 of the drawing has a different from the arrangement of the link plates in the Fig. 1 and Fig. 2 arrangement of the individual link plates.
  • a lashing chain formed from juxtaposed triple bonds according to the arrangement of FIG. 3 also has a better load behavior than the known link chain, ie lower tensile forces in the link plates and lower compressive stresses in the rocker pressure element at the predetermined load collective in the converter approach point.
  • the triple bandage according to FIG. 5 of the drawing is characterized by the fact that a lashing chain constructed therewith has lower tensile forces in the individual link plates and lower bending stresses in the given load collective than the individual weighing pegs, as is the case with the known link chain.
  • the invention thus provides a link chain which provides the above-described object, namely a better evaluation collective for the given load collective in the converter approach point of the cone pulley belt drive equipped therewith, than is the case with the known link chain.
  • the link chains formed with the triple bonds according to the invention are also distinguished by the fact that they appear less acoustically than the known link chain.
