Definitions
- the present invention relates to a link chain for in particular a vehicle drive, with a plurality of hingedly interconnected via pressure pieces link plates, the pressure pieces are transverse to the longitudinal direction of the link chain and arranged in openings of the link plates and formed on the pressure pieces and the link plates respective curved trained contact surfaces are along which abut the pressure pieces and link plates for power transmission to each other and the contact surfaces are formed in a running in the longitudinal direction of the link chain cross-section at the pressure pad height direction upper and lower contact surface area between the pressure piece and link plate.
- the tab plate described at the beginning can be used, for example, as a traction mechanism in a bevel belt transmission.
- the chain thereby runs between two spaced pairs of conical disks and transmits the output torque originating from a drive motor via a frictional engagement between the pressure pieces and the conical pulley pairs.
- known tab chains for the so-called acoustic randomization consist of two short and two long link plates.
- Such a link chain therefore has short and long link plates, of which, in addition, each link plate also uses link plates which have a so-called overlap tab or a so-called knuckle-securing catch.
- the overlap tab is usually formed on the short link plate and it should be achieved so that the overlap with the tabs of the next but one link remains in the right positions in a neighboring link with long link plates.
- the link chain is subjected to a reversal of the direction of rotation in which a respective chain trump is transferred from the elongated position into a folded-down position.
- handling operations take place on the link chain, in which the risk of the link chain buckling both inwardly and outwardly. exists.
- the overlapping lugs attached to the short link plates now ensure that the overlap of the link plates is maintained and slipping and jamming of the link plates is avoided.
- the present invention is based on the object, the tab chain such that the constructive and monetary effort in the design and manufacture of the tab chain can be reduced and beyond the tab chain can be made faster.
- the invention now provides, in order to achieve the abovementioned object, a plate-link chain for, in particular, a vehicle drive, with a plurality of pressure plates.
- pivotally interconnected link plates wherein the pressure pieces are transverse to the longitudinal direction of the link plate and are arranged in the openings of the link plates and formed on the pressure pieces and the link plates respective curved trained contact surfaces along which rest the pressure pads and link plates for power transmission to each other and the contact surfaces in a running in the longitudinal direction of the link chain cross section are formed in Druck Bristolnraum upper and lower contact surface area between thrust piece and link plate, wherein the opening of the link plate is formed in the area between the contact surfaces of the link plates in the direction of curved inwards.
- the link plates of the plate-link chain according to the invention have an opening for receiving the rocker pressure pieces, in which the area between the contact surfaces of the link plates is curved in the direction towards an imaginary center of the opening directed inwardly.
- the plungers are curved in the area between the contact surfaces of the plungers designed inwardly, ie viewed in the direction of an imaginary center of the plungers towards inwards.
- This curved trained portion of the pressure pads between the contact surfaces is then opposite the arranged in the opening of the link plate rocker pressure piece in the direction of inwardly curved area between the two contact surfaces of the link plate.
- the plungers are therefore convex in relation to a pressure piece center in the area of the contact surfaces of the plungers and come at a, a predetermined bending angle exceeding buckling of the link chain with the transition region between the convex and concave curvature relative to a center of the opening of the link plate engaged, so it Thus comes to a contact between the adjacent to the contact surface of the pressure piece transition region and the transition region between the convex and concave curvature of the opening of the link plate comes on the Thus, an elevation forms over which the pressure piece can not be moved when the chain link is used as intended, ie can not be twisted.
- the quasi-starting of the transition region of the pressure element at the transition region of the link plate ensures that the link chain can not be bent inwards or outwards over a predetermined bending angle.
- a body of the link plate enclosing the opening in the area between the contact surfaces of the link plate From the opening directed away extension or tip, which is intended to rest on in the running direction of the link chain adjacent link plates or their corners.
- This extension which can also be referred to as a tip, thus serves to ensure that its overlap with a corresponding tip of the chain link after the second ensures that this overlap is maintained even with bent link plate and thus the link plates can not slip to each other and not can jam each other, which could otherwise lead to a corresponding failure of the link chain.
- such an extension is provided on the body in the running direction of the link chain at both ends.
- the lug chain provided according to the invention is now characterized in that instead of two chain lashes, each with or without overlap latches or Verknickêts-, so four different types of luff, only two longer in the direction of the link chain chain chain chain types are provided, so compared with known Laschen chains, for example, provided by punching finished the chain straps, four tools are no longer necessary, but only two tools and beyond the chain straps can be transported in the production of the link chain, for example by means of a vibratory conveyor, and the link plates in two out of four possible layers can be used so that the average output of the vibratory conveyor increases with an assumed same number of strap types per chain by 33% compared to the four known types of chain link.
- Laschen chains for example, provided by punching finished the chain straps
- four tools are no longer necessary, but only two tools and beyond the chain straps can be transported in the production of the link chain, for example by means of a vibratory conveyor, and the link plates in two out of four possible layers can be used so that the average output of the vibr

- Chain link arranged rocker pressure piece which is here a short link plate
- Fig. 2 is a view - similar to Fig. 1 - a long link plate.
- Fig. 1 of the drawing shows a plan view of a short link plate 1, in the opening 2 for ease of illustration instead of two pairs of pressure pieces only one pressure piece 3 is shown arranged.
- contact surfaces 7, 8 are formed both on the thrust piece 3 and on the body, along which rest the thrust piece 3 and the link plate 1 for power transmission to each other.
- a contact surface 9 and the body 5 a contact surface 10 is formed at the lower contact surface area 6 between the pressure piece 3 and the link plate 1 on the pressure piece 3.
- both the upper abutment surface 8 and the lower abutment surface 10 of the body 5 are curved outwardly, ie formed convex.
- both the upper abutment surface 7 and the lower abutment surface 9 of the pressure piece 3 are convex relative to a center 12 of the pressure piece 3.
- the opening 2 is concave between the upper abutment surface 9 and the lower abutment surface 10 of the body 5, that is to say the intermediate region 13 is concave relative to the center 11 of the opening 2 and also the intermediate region 14 of the abutment 3 assigned to this intermediate region 13 is in the region between upper contact surface 7 and the lower contact surface 9 is concave.
- an upper transition region 15 is formed between the abutment surface 7 and the intermediate region 14, which faces an upper transition region 16 between the upper abutment surface 8 and the intermediate region 13 on the side of the body 5.
- the pressure pad 3 comes with its own upper transition region 15 at the upper transition region 16 of the link plate 1 in contact and prevents kinking of the link chain beyond a predetermined bending angle addition.
- the pressure piece 3 comes with its formed between the intermediate region 14 and the lower abutment surface 9 lower transition region 17 with the lower transition region 18 formed between the intermediate portion 13 of the body 2 and the lower abutment surface 10 of the body 2 in contact, if the link chain formed from short link plates 1 and long link plates 19 in the direction of the arrow P of FIG. 1 is subjected to a deflection that goes beyond a predetermined bending angle, so that the engagement between the lower transition region 17 of the pressure element 3 and the lower transition region 18 of the link plate 1 ensures that the plate chain can not be bent over the predetermined bending angle in the direction of the arrow P to the outside.
- Fig. 2 of the drawing now shows a long link plate 19, with only one arranged in the opening 2 pressure piece 3.
- the long link plate 19 differs from the short link plate 1 shown in Fig. 1 by a longitudinal direction A of the link chain considers greater longitudinal extent and thus represents a long link plate, which can be used for acoustic randomization in conjunction with the short link plate shown in Fig. 1.
- both on the body 5 of the long link plate 19 and on the body 5 of the short link plate 1 are each an extension 20 formed at both ends of the link plates 1, 19, which ensures as overlap tabs that adjacent link plates can not slip to each other and can not jam and thus Due to the overlap of the extensions or lobes 20 with extensions or corners 20 of the chain link next but one cover is achieved, which avoids slipping and jamming the link plates 1, 19.
- the link chain according to the invention is formed only on the basis of the chain link types of different lengths in the running direction of the link chain according to the short link plate 1 and the long link plate 19.
