Problems solved by technology

As a result, said axial alignment force is also limited in practice, whereby unfavorable friction between the axial sides of the carrier ring and the transverse section, or the pulley, or both transverse section and pulley, is even possible is that abrasive contacts can easily occur, said unfavorable contacts leading to undesired wear at least in long-term operation

Embodiment Construction

[0018] In the drawn figures, the same reference numerals refer to the same or similar structures and / or components.

[0019] figure 1 A schematic diagram of a continuously variable transmission of , showing a drive belt 3 running on two pulleys 1, 2 and comprising a flexible endless carrier or carrier ring 31 and a substantially continuous row of transverse segments 32, said transverse segments 32 is mounted on the bearing ring 31 and arranged along the circumferential direction of the bearing ring 31 . In the illustrated configuration of the transmission, the upper pulley 1 will rotate faster than the lower pulley 2 . By varying the distance between the two conical disks 4, 5 of the pulleys 1, 2, the so-called running radius R of the drive belt 3 on each pulley 1, 2 can be varied in a mutually cooperative manner, and thus, The (transmission) ratio between the rotational speeds of the two pulleys 1, 2 can be varied.

Abstract

A transverse section (32) of a drive belt (3) for a continuously variable transmission is provided with two notches (33), each notch (33) being formed in one direction by a radially outward saddle of the transverse section (32) A surface (42) is bounded, said saddle surface (42) being convexly curved according to a local radius of curvature of at least The average local radius of curvature is smaller on average than the corresponding opposite axial side of the saddle surface (42).

Description

technical field [0001] The invention relates to a transverse section of a drive belt for a continuously variable transmission of a motor vehicle as defined in the preamble of claim 1 below. Background technique [0002] Such transverse segments and drive belts provided with such transverse segments are known and described, for example, in European patent applications EP-A-0626526 and EP-A-1566567. Known drive belts consist of a plurality of steel transverse sections and two endless, i.e. ring-shaped, bearings, each of which extends through grooves provided on either transverse side of the transverse sections, whereby the transverse sections consist of The carrier ring supports and guides. Typically, the load bearing rings are also made of steel and each load ring consists of a number of individual continuous straps which fit tightly around each other. The transverse segments are neither fixed to each other nor to the carrier ring, thereby making them movable relative to th...
