  • Patent number: 10203021
    Abstract: The disclosure relates to a transverse segment (33) for a drive belt with a carrier ring and with a plurality of these transverse segments (33) that are placed slideably on the carrier ring, which transverse segments (33) are provided with main body surfaces (38, 41), where between the transverse segment (33) extends in thickness direction, one main body surface (38) being provided with a rocking edge (42) that defines a transition between an upper side and a tapered lower side of the transverse segment (33) with a lowermost edge (34). The lower side of the transverse segment (33) includes at least one opening (44) and at least an upper, radially outward limiting boundary surface (46) of the opening (44) is provided with an undulating shape, i.e. is provided with multiple protrusions (47) that protrude generally towards the lower, radially inward limiting boundary surface (46) of the opening (44).

  • Patent number: 7303496
    Abstract: A transverse element for a push belt for a continuously variable transmission comprises a supporting surface for supporting a carrier of the push belt, and a pulley sheave contact surface for contacting pulley sheaves of the continuously variable transmission. A curved transition surface is connected to the supporting surface, whereas a distance surface is located between this transition surface and the pulley sheave contact surface. The distance surface is positioned lower than the supporting surface. When the transverse element collides with a relatively large collision element like another transverse element, protrusions may be developed exclusively on the distance surface. These protrusions are not capable of inflicting damage on a carrier which is to be laid on the supporting surface, because these protrusions do not protrude beyond the level of the supporting surface.

  • Patent number: 7201689
    Abstract: Driving belt provided with an enclosed tension element and metal transverse elements accommodated so as to be movable in a longitudinal direction along the tension element. The transverse elements each comprise a body part, a head part and a neck part therebetween. On either side of the neck part between the body part and the head part two axially oriented openings are present, for accommodating in each a part of the tension element. The body part includes side contact surfaces oriented substantially in an axial direction and diverging from each other in the radial direction, and with a substantially axially oriented tilting line and in which an upper limit of an opening formed by the head part extends in the axial direction at least to an imaginary line, which extends from the radially lower limit to the radially upper limit of the respective opening in line with a contact surface.

  • Publication number: 20040152550
    Abstract: Driving belt provided with an enclosed tension element (2) and also with metal transverse elements (1) accommodated so as to be movable in a longitudinal direction along the tension element (2), which transverse elements are each designed with a body part (10), a head part (12) and a neck part (11) between the latter two parts, on either side of the neck part (11) between the body part (10) and the head part (12) two axially oriented openings (17) being present, in each of which openings a part of the tension element (2) is accommodated, the body part (10) being provided on either side with contact surfaces (13) oriented substantially in an axial direction and diverging from each other in the radial direction, and with a substantially axially oriented tilting line (14) and in which an upper limit (16) of an opening (17) formed by the head part (12) extends in the axial direction at least to an imaginary line (18), which extends from the radially lower limit (19) to the radially upper limit (16) of the respect
