  • 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: 7029411
    Abstract: A driving belt for use in a continuously variable transmission comprising two V-shaped pulleys, which driving belt comprises a carrier consisting of two endless band packages lying side by side, on which transverse elements are disposed. Each transverse element includes two recesses positioned opposite each other for receiving the band packages, wherein a part of the transverse element is positioned between said band packages. The front side of the transverse element includes a projection, which can mate with a recess in the adjacent transverse element. Said projection and said recess are at least partially formed in the aforesaid part of the transverse element.

  • Patent number: 6676553
    Abstract: A driving belt for use in a continuously variable transmission includes two V-shaped pulleys. The driving belt includes a carrier of two endless band packages lying side by side, on which transverse elements are disposed. Each transverse element includes two recesses positioned opposite each other for receiving the band packages, so that a part of the transverse element is positioned between the band packages. Each recess includes an inside surface facing towards the band package, wherein the portion of the inside surface that is formed by the aforesaid part of the transverse element includes an acute angle, near the underside of the band packages, with the plane in which the band packages lie.
