Problems solved by technology

That is, a flat-link chain bent beyond a predetermined bending angle can lead to premature failure of a conical-disk winding contactor transmission equipped with such a flat-link chain due to the torsion of the pressure piece, which may also be referred to as a rocking pressure piece below.

Embodiment Construction

[0019] Attached figure 1 A top view of a short link piece 1 is shown, in order to simplify the representation, only one pressure piece 3 is arranged in the hole 2 of the short link piece instead of two pairs of pressure pieces.

[0020] In the upper contact surface region 4 between the pressure part 3 and the base body 5 of the connecting web 1 , contact surfaces 7 , 8 are formed both on the pressure part 3 and on the base body 5 , along which the pressure part 3 and the connecting web 5 are formed. These abutment surfaces rest against each other to transmit force.

[0021] Similarly, in the lower contact area region 6 between the pressure part 3 and the link web 1 , a contact surface 9 is formed on the pressure part 3 and a contact surface 10 is formed on the base body 5 .

[0022] Both the upper abutment surface 8 and the lower abutment surface 10 of the base body 5 are curved outwards with respect to the center 11 of the bore 2 , ie are convex.

Abstract

The invention provides a plate link chain for, in particular, a vehicle drive, having a multiplicity of plate links (1, 19) which are connected to one another in an articulated manner via pressure pieces (3), wherein the pressure pieces extend transversely with respect to the longitudinal direction of the plate link chain and are arranged in openings (2) of the plate links (1, 19), and respectivebearing faces (7, 8, 9, 10) of curved configuration are formed on the pressure pieces and the plate links, along which bearing faces (7, 8, 9, 10) the pressure pieces and plate links bear against oneanother for the transmission of force, and the bearing faces are formed on the upper (4) and lower (6) contact face region in the vertical direction of the pressure pieces between the pressure piece (3) and the plate link (1, 19); in a cross section which extends in the longitudinal direction of the plate link chain, wherein the opening (2) of the plate link is of inwardly curved configuration inthe region between the bearing faces (8, 10).

Description

technical field [0001] The invention relates to a flat-link chain, in particular for a vehicle drive, which has a plurality of links connected to each other in an articulated manner by pressure pieces, wherein the pressure pieces are arranged transversely to the longitudinal direction of the flat-link chain Extending and being arranged in the hole of the link piece, on the pressure piece and the link piece, there are correspondingly configured arched abutment surfaces, along which the pressure piece and the link piece bear against each other to transmit force, these abutment The surfaces are formed in a cross section extending in the longitudinal direction of the flat link chain on the upper contact surface area and the lower contact area area in the height direction of the pressure piece between the pressure piece and the link plate. Background technique [0002] Flat-link chains of the type mentioned at the outset are already known from the unpublished patent application D...
