Embodiment Construction

[0017] 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.

[0018] 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 drive belt (3) for a continuously variable transmission with transverse members (1; 1-a, 1-b), comprising a base part (10) and two pillar parts (11; 1-l, 11-r), each provided on a respective axial side of the base part (10), which transverse members (1) are mounted slideably on an endless carrier (8). The drive belt (3) includes two types of transverse members (1-a, -b), whereof each type is provided with only one hook 10 part (13-a; 13-b) or with one larger hook part (13-a; 3-b) that extends in axial direction over the endless carrier (8). Between the two respective types of transverse members (1-a, 1-b) the said one or the said larger one hook part (13-a; 13-b) is respectively 1 associated with an opposite one of the two pillar parts (11-l, 11-r).

Description

technical field [0001] The invention relates to a 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 (i.e. endless) carrier comprising at least one, but usually a set of nested flexible loops, and a plurality of transverse elements along the length of the endless carrier. together form a substantially continuous row. Both said flexible loops of the drive belt and said transverse elements are usually made of metal, especially steel. Background technique [0002] Each transverse element comprises a base extending predominantly widthwise (ie axially) with respect to the circumference of the drive belt and two posts having an at least effectively trapezoidal profile extending from the base The corresponding axial sides of the drive belt extend along a direction substantially perpendicular to the aforementioned axial and circumferential d...
