Patent number: 11506257Abstract: An element of a transmission including: a rocking edge portion with a convex surface formed on one of a front face and a rear face, so that the rocking edge portion extends over a pillar portion at least partially, the rocking edge portion having a contact line where the adjacent elements contact each other serves as a fulcrum of rotation of the adjacent elements; and a recessed non-contact portion extends along the saddle surface, to avoid contact with the adjacent element, and that divides the rocking edge portion in the width direction at least partially. A depth of the non-contact portion is set so that an end portion of the non-contact portion is positioned on an inner peripheral side of the transmission belt relative to the contact line when a winding radius is minimized, and the end portion does not reach the trunk portion on the inner peripheral side.Type: GrantFiled: August 1, 2018Date of Patent: November 22, 2022Assignee: AISIN CORPORATIONInventors: Akira Ochi, Takayuki Miyake

Patent number: 11466757Abstract: 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.Type: GrantFiled: May 14, 2018Date of Patent: October 11, 2022Assignee: AISIN CORPORATIONInventors: Takayuki Miyake, Akira Ochi, Wataru Ishihara, Junichi Tokunaga

Patent number: 11454299Abstract: 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.Type: GrantFiled: June 1, 2018Date of Patent: September 27, 2022Assignee: AISIN CORPORATIONInventors: Akira Ochi, Wataru Ishihara, Takayuki Miyake, Junichi Tokunaga

Patent number: 11320023Abstract: 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.Type: GrantFiled: May 14, 2018Date of Patent: May 3, 2022Assignee: AISIN CORPORATIONInventors: Wataru Ishihara, Akira Ochi, Takayuki Miyake, Junichi Tokunaga

Patent number: 11287014Abstract: 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”.Type: GrantFiled: June 6, 2018Date of Patent: March 29, 2022Assignee: AISIN CORPORATIONInventors: Takayuki Miyake, Akira Ochi, Wataru Ishihara, Junichi Tokunaga

Patent number: 11149820Abstract: In an element of a power transfer belt to be wound around a primary pulley and a secondary pulley of a continuously variable transmission to transfer torque, the distance from a boundary line between a surface positioned on the outer peripheral side of the power transfer belt with respect to a rocking edge portion and the rocking edge portion to a saddle surface is determined from the slip amount due to micro slip which is relative slipping between the element and the primary pulley caused when the primary pulley pushes out the power transfer belt toward the secondary pulley, and the angular speed of the element and the angular speed of a ring in a range in which the power transfer belt is wound around the secondary pulley.Type: GrantFiled: March 5, 2018Date of Patent: October 19, 2021Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryo Nakamura, Akira Ochi, Takayuki Miyake, Junichi Tokunaga, Keisuke Ninomiya, Yu Inase, Fumiya Kaji, Yuji Hattori, Yuji Nagasawa
