Problems solved by technology

This (periodically occurring) deformation is not necessarily detrimental to the operation of the variator, however, in all-metal drive belts currently under consideration, premature failure due to metal fatigue of the transverse elements may occur

Embodiment Construction

[0026] figure 1 The core components of a continuously variable transmission used, for example, in a drive train of a passenger motor vehicle are shown schematically. This transmission is known per se and includes at least a first variable pulley 101 and a second variable pulley 102 . In this transmission system, a first pulley 101 is coupled to and driven by an engine and a second pulley 102 is coupled to driven wheels of a motor vehicle, typically by means of a plurality of gears.

[0027] The transmission pulleys 101, 102 each include a first tapered pulley plate secured to a pulley shaft member 103, 104 of the respective pulley 101, 102, and a second tapered pulley plate that The discs are axially displaceable relative to the respective pulley shaft 103 , 104 and are fixed on the respective pulley shaft 103 , 104 only in rotational direction. The drive belt 50 of the transmission is wound around the pulleys 101 , 102 while being located between the sheaves of the pulleys...

Abstract

A transverse member (32) for a drive belt (3) includes a base part (10) and two pillar parts (11) that extend from a respective lateral side of the base part (11), generally in the same direction. Furthermore, the transverse member (32) includes a separate support beam that extends between the pillar parts (11) at a distance from the base part (10).

Description

technical field [0001] The invention relates to a metal drive belt for a continuously variable transmission having two pulleys for receiving the drive belt between its at least partially conical pulley pulleys. Known drive belts comprise an endless, or endless, carrier, comprising at least one, but usually a set of nested, flexible metal rings, and a plurality of metallic transverse elements along the endless carrier. together form a substantially continuous row. Each transverse element comprises a base extending mainly widthwise or axially and two posts having a trapezoidal or at least effectively trapezoidal profile, each of which extends from the The respective axial sides extend in a direction substantially perpendicular to the aforementioned axial and circumferential directions of the drive belt, ie in a radial direction. Each transverse element thus defines a centrally located opening between its post and base, wherein a small circumferential section of the endless car...
