摘要： Method for operating a continuously variable transmission provided with two pulleys, each provided with two pulley discs which together define a tapering groove and between which a drive belt is clamped with the aid of an axial clamping force for transmitting a torque supplied to the transmission, during normal operation of the transmission, from one pulley to the other pulley with the aid of friction between the discs and the drive belt. The transmission is operated by an electronic operating unit which can influence at least the axial clamping force, wherein when the transmission is operating, the degree of movement between the pulley discs and the drive belt, i.e. drive belt slip, is detected by the operating unit with the aid of slip-detection means, and when the said degree of drive belt slip exceeds a critical limit, the operating unit uses an operating measure to actively reduce the degree of drive belt slip. The said critical limit is preferably determined as a function of a maximum permissible degree of the drive belt slip for the instantaneous transmission ratio of the transmission and the axial clamping force.

摘要： A transverse element (20) for a drive belt for a continuously variable transmission is disclosed. The drive belt comprises two endless carriers (12), wherein transverse elements (20) are continuously arranged along the entire length of the carriers (12).
The transverse elements (20) are on both sides provided with recesses (21) for at least partially receiving the carriers (12). A portion of the inner surface of a recess (21) constitutes a supporting surface (22) for supporting a carrier (12).
The supporting surface (22) is connected to a side surface (38) of a neck portion (30) of the transverse element (20), through a lower transition region (37). Said neck portion (30) comprises the portion of the transverse element (20) being situated between the recesses (21). The neck portion (30) tapers in the direction of the supporting surfaces (22).

摘要： A transverse element (23) for a drive belt for a continuously variable transmission is disclosed. The drive belt comprises two endless carriers (20), wherein transverse elements (23) are continuously arranged along the entire length of the carriers (20). The transverse elements (23) are on both sides provided with recesses (30) for at least partially receiving the carriers 920). Furthermore, the transverse elements (23) comprise supporting surfaces (31) for supporting the carriers (20), as well as pulley sheave contact surfaces (32) for the purpose of contact between the transverse elements (23) and pulley sheaves of the continuously variable transmission. A convex transition region (33) which has two parts having different curvature radii is situated between a supporting surface (31) and a pulley sheave contact surface (32), wherein a first curvature radius of a first part at the side of the supporting surface (31) is larger than a second curvature radius of a second part at the side of the pulley sheave contact surface (32).
