Definitions

• the present invention relates to a link chain for a particular 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 are arranged in openings of the link plates and arranged 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 arranged on the pressure pieces curved rolling surfaces are arranged along which roll the plungers for power transmission to each other and the plungers are formed asymmetrically in a running in the longitudinal direction of the link chain cross section in Druck Bristolnraum and the contact surfaces on are provided in the pressure piece height direction upper and lower contact surface area between the pressure piece and link plate.
• Such a link chain can be a toothed chain, which can be used, for example, in a transfer case of a motor vehicle or as a drive chain for an auxiliary unit of the internal combustion engine of the motor vehicle.
• the link chain can be designed as a toothed chain and transmits traction from a driving to a driven sprocket.
• Such a link chain as it has been called input, but for example can also be used as a traction transfer means in a conical-pulley transmission for a motor vehicle or the like, while transmitting the tensile force by means of frictional contact between the pressure pads and the conical disc surfaces of the two cone pulley pairs.
• asymmetric pressure pieces are used in openings of the link plates, and this has to be done so that the rolling surfaces of the pressure pieces are associated with each other.
• the asymmetric plungers must be used positionally oriented in the openings, so that the openings in the, the wider upper parts of the plungers corresponding areas are wider. As already mentioned above, it must be ensured that the asymmetrical pressure pieces are used in a positionally oriented manner in the openings of the link plates.
• the present invention is based on the object, the tab chain in such a way that a faulty installation situation of the plungers in the link plates is not possible.
• the invention therefore provides a solution to this problem, a link chain for a particular vehicle drive with a plurality of hingedly articulated together link plates, the pressure pieces are transverse to the longitudinal direction of the link chain and arranged in openings of the link plates and curved at the pressure pieces and the link plates respectively trained abutment surfaces are arranged, along which abut the pressure pieces and link plates for power transmission to each other and arranged on the pressure pieces curved Wälz vom along which the pressure pieces for power transmission to each other and the pressure pieces are formed asymmetrically in a running in the longitudinal direction of the link chain cross section in Druck demoeux and the contact surface on in Druck demoeux upper and lower Contact surface area between the pressure piece and link plate are provided, wherein the opening of the link plate has at least one inwardly curved area.
• the invention provides a link chain which has link plates, in which the opening for receiving a pressure piece pair has at least one area narrowing the opening by a region curved inward, so that insertion of the pressure pieces into the opening only in the correct position Alignment of the pressure pieces to each other is possible and faulty alignment of the pressure pieces relative to each other, an overlap of the inwardly curved portion with at least one of the pressure pieces occurs and thus the pressure piece can not be inserted into the opening.
• the area is a protrusion extending concavely away from a convex peripheral edge and extending inwardly from the convex peripheral edge in the direction of the opening, such that insertion of the Pressure pieces in the opening only at the intended position of the pressure pieces to each other is possible and otherwise the plungers or at least one of the plungers can not be inserted into the opening and thus with respect to the position of the plungers relative to each other and to the link plates faulty installation of the plungers not possible is.
• the asymmetric plungers have on a back surface opposite the rolling surface a cutout, which can be used to accommodate manufacturing tolerances in the production of the plungers in an advantageous manner. It is provided according to the invention that the inwardly curved portion of the link plate is arranged at the intended arrangement of the pressure piece in the opening on a, the free punch largely opposite region of the peripheral edge, so the concave edge extending concave away projection on the link plates is provided so that it lies opposite the cutout of the plungers. In this case, it is also advantageously achieved that the region curved inwards uses the installation space available due to the clearance of the pressure pieces, and since this free cut of the pressure pieces is in the lower region of the pressure zone viewed in the running direction of the link chain.
• the inwardly directed curved portion of the link plate may also be provided in the lower region of the link plate openings, ie in a region which is problematic in the known link chains with respect to the concentration of stress and thus due to the inwardly curved region an enlargement of the Power transmission available cross-sectional area of the link plate is achieved and thus decreases the material tension in the link plate at a given force.
• the invention also provides a link plate for a link chain, as described above, with two openings for receiving two pairs of pressure pieces, wherein the link plate according to the invention is developed so that each opening extending from the peripheral edge of the opening inwardly Owns area.
• This inwardly extending portion is formed in an advantageous manner at a location which is opposite to the point of free cutting of the pressure pieces to be arranged.
• the link plate is therefore provided with an area which is further complementary in shape and surface to a free cut formed on a back surface of pressure pieces and extends so far into the opening that an overlap of the area with pressure pieces takes place relative to one of a proper orientation to the opening deviating alignment of the plungers.
• An assembly or insertion of the pressure pieces in the opening is therefore possible only with the proper orientation of the pressure pieces relative to the opening of the link plate and therefore only with a simultaneous intended alignment of the plungers relative to each other and not in a faulty orientation.

• a pressure piece pair of asymmetric pressure pieces 2, 3 is inserted into an opening 4 of the link plate 1.
• it is the pressure piece 2 to a so-called fixed pressure piece, as this is caulked with a perpendicular to the plane considered lower link plate and an upper link plate, which receive a stack of link plates 1 between them.
• pressure piece 3 is a shorter than the pressure piece 2 formed free pressure piece, which is not caulked with the lower and upper link plate, as is the case with the pressure piece 2 and has a rolling surface 5, which roll on a rolling surface 6 of the pressure piece can.
• an upper contact surface 7 and a lower contact surface 8 in the region of the opening 4 are provided which cooperate with an upper contact surface 9 and a lower contact surface 10 of the pressure element 3 for transmitting power.
• the distance between the contact surfaces shown in Fig. 1a is shown enlarged to explain the respective contact surfaces.
• Fig. 1a of the drawing shows a proper positionally correct installation situation of the rocker pressure pieces 2, 3 in the opening 4 such that the respective, in the width direction (double arrow B) shown wider areas of the asymmetric plungers 2, 3 are arranged opposite to each other.
• a link plate 11 is provided with an opening 12 which has a directed inwardly curved portion 13.
• Fig. 2a of the drawing shows a correct position assembly and thus intended alignment of the plungers 2, 3 in the opening 12 to each other.
• the plungers 2, 3 have a, the rolling surfaces 5, 6 opposite, formed on a back surface 14 cutout 15 which is disposed largely opposite the inwardly curved portion 13, the area 13 so at a proper arrangement of the plungers 2, 3rd in the opening 12 at a free cut 15 substantially opposite region of the peripheral edge 16 of the opening 12 is located.
• FIG. 2b now shows the conditions that would result in a due to an incorrect orientation of the plungers 2, 3 to each other resulting installation situation of the plungers in the opening 12 of the link plate 11 according to the invention.
• the pressure piece 2 is in turn arranged in the correct position in the opening 12, while due to, for example, a faulty promotion of a used by the mounting plate of the invention Laschenkette vibrating conveyor wrong orientation of the pressure piece 3 would create a faulty installation situation, as shown in Fig.
• the inwardly curved region 13 that the available for power transmission cross-sectional area of the link plate 11 (see 2a), thus reducing the workpiece stresses in the link plate 1.
• the region 13 is now viewed from a center of the aperture 12 at an angle of approximately 45 degrees to the horizontal line through the center, thus, the enlarged cross-sectional area then extends in a region of the link plate 1, which is stress-critical in known link plate constructions, so that the invention is also advantageous in terms of stress concentration in this area.
