摘要： Drive belt for use in a continuously variable transmission, such as for passenger cars, with two pulleys around which the drive belt (3) is positioned, which drive belt (3) comprises a continuous band set (31) on which a large number of transverse elements (33) are arranged, which elements can move along the band set (31) at least in a circumferential direction, the band set (31) comprising at least two adjacent, relatively thin metal bands which are nested together in the radial direction, wherein, given a combined surface roughness of the said two adjacent bands, a coefficient of friction which is active in a frictional contact between the said two adjacent bands has a minimum value as a function of the quotient of a differential velocity in the circumferential direction and a contact pressure between the said bands.

摘要： Drive belt (3) provided with a continuous band set (31) on which a large number of transverse elements (33) are arranged, the band set (31) comprising at least a number of metal bands (32) which are nested together in the radial direction and are relatively thin, with a difference in circumferential length existing between at least two adjacent bands (32; x, x+1) of the band set (31) between the outer side (36) of the inner band (32; x) and the inner side (35) of the outer band (32; x+1). According to the invention, at least if the said difference has a positive value, a coefficient of friction (µx+1,) which is active in a frictional contact between the two adjacent bands (32; x, x+1) while the drive belt (3) is operating is selected to be greater than a coefficient of friction (µx) which is active in a frictional contact on the inner side (35) of the radially inner band (32; x) of the said two adjacent bands (32; x, x+1), and vice versa.

摘要： Method of operating a continuously variable transmission comprising a drive belt (3) that is clamped between and in frictional contact with the discs (4,5) of a pulley (1; 2) of the transmission under the influence of a normal force Fn, in particular for regulating the lubrication thereof, wherein a flow of lubricant fed to the belt (3) and/or pulley (1; 2) of the transmission is regulated in proportion with either the temperature of the lubricant or an amount of slip S of the belt (3) relative to the pulley (1; 2) in the said frictional contact.

摘要： Drive belt (3) provided with an endless tensile means (31) and a number of relatively thin transverse elements (32) that are slidably mounted on the tensile means (31) and that have a front main face (40) and a rear main face (41), which are mutually separated over a thickness of the element (32) and which are predominantly oriented in the longitudinal direction of the drive belt (3), and that also have two side faces (36) one provided on each lateral side of the element (32) for arriving into a frictional contact with a pulley (1, 2) of a transmission in which the drive belt (3) is to be applied. Each side face (36) of the element (32) merges with a respective further surface (40; 41; 52),which is at least predominantly oriented in the longitudinal direction of the drive belt (3), through a transition surface (50; 50(a), 50(b), 50(c)) represented by a relatively sharp edge, which in cross-section may be described, at least effectively, by an arc having a radius of curvature equal to, or smaller than 0.3 mm.

摘要： The invention relates to a drive belt for continuously variable transmission for motor vehicles, provided with two pulleys, each comprising two substantially conical pulley sheaves, between which the drive belt can be held at a variable radial position, which drive belt is provided with transverse elements (32), which on both lateral sides are provided with a flank (40) that is intended for frictional contact with the pulleys, and which, at least in its height direction, i.e. radially relative to the pulleys (1, 2), is provided with a convex curvature, in which flank (40) one or more grooves (41) are provided.
