  • Patent number: 11466757
    Abstract: A continuously variable transmission includes a transmission belt including a plurality of elements and a ring and wound around V-grooves of first and second pulleys, each of the plurality of elements including a body portion having a saddle surface and a pair of pillar portions extended from the body portion so as to be located on both sides in a lateral direction of the saddle surface, and the ring being disposed between the pair of pillar portions of each of the plurality of elements. When one of the first and second pulleys has its minimum groove width, at least a part in a thickness direction of the ring wound around the one of the first and second pulleys protrudes radially outward beyond an outermost circumference of a surface of the V-groove of the one of the first and second pulleys.

  • Patent number: 11466752
    Abstract: Elements of a transmission belt wound around pulleys of a continuously variable transmission each include a body part, a pair of pillar parts, and a pair of side surfaces. The pair of side surfaces each include a first side surface formed on a corresponding one of the pillar parts; and a second side surface formed so as to continue from the first side surface, and located more on an inner circumference side than the first side surface.

  • Patent number: 11454299
    Abstract: An element for a transmission belt that is wound around a primary pulley and a secondary pulley of a continuously variable transmission includes: a trunk portion having a saddle surface that is in contact with a ring of the transmission belt; and a pair of pillar portions extending from the trunk portion so as to be positioned on both sides of the saddle surface in a width direction. The saddle surface is a convex surface that is formed by an elliptic arc and satisfies b/a?0.015 when a long diameter of the elliptic arc is regarded as “a” and a short diameter of the elliptic arc is regarded as “b”. In this way, it is possible to optimize the stress distribution of the ring that is in contact with the saddle surface and improve the durability of the ring and the transmission belt.

  • Patent number: 11320023
    Abstract: A continuously variable transmission includes a transmission belt including a plurality of elements each including a pair of pillar portions and a ring arranged between the pair of pillar portions of each of the plurality of elements, and a lubricant supply portion arranged on an inner side of the transmission belt in a radial direction. Each of the plurality of elements further includes a pair of rocking edge portions formed away from each other in a width direction, and a non-contact portion extending between the pair of rocking edge portions in the width direction along a saddle surface. A clearance that communicates the non-contact portion and a region on an inner side in the radial direction with respect to the transmission belt is formed between the elements included in a looped portion of the transmission belt around a first or second pulley.

  • Patent number: 11287014
    Abstract: An element of a transmission belt includes a pair of rocking edge portions with a convex surface, these are formed on one of a front face and a rear face to extend a part of the rocking edge portion over a pillar portion, and the rocking edge portions are spaced away from each other in a width direction; and a non-contact portion extended along a saddle surface in the width direction between the rocking edge portions, in non-contact with an adjacent element. S/A?3.5 is satisfied, when a sum of widths of end portions of the rocking edge portions on an outer peripheral side of the transmission belt is set as “A”. A sum of surface areas of parts of the pillar portions on the outer peripheral side of the transmission belt is set as “S”.

  • Publication number: 20200132160
    Abstract: A driving belt that can limit damages on a hoop and elements. A boss projecting from a front surface of the element is inserted into a hole formed on a rear surface of the fellow adjacent element to form an element array, and the element array is fastened by a hoop. A radially inner clearance between a leading edge of the boss of the element and the hole of the fellow adjacent element in the radial direction is set wider than a radially outer clearance between the leading edge of the boss of the element and the hole of the fellow adjacent element in the radial direction, within a straight region of the driving belt between the pulleys.
