  • 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: 11448292
    Abstract: To provide a tensioner that can keep the oil pressure in an oil pressure chamber stable and consistently generate suitable reaction force and damping force to impact loads to reduce looseness in the chain and noise. A piston is set such as to partition an inner space of a plunger into an adjustment space on the front side and the oil pressure chamber on the rear side, a piston restricting member restricting the movement of the piston toward the adjustment space. An oil relief mechanism is configured to cause the piston to move forward when oil pressure in the oil pressure chamber rises so as to discharge oil inside the oil pressure chamber to the outside. The piston restricting member has an orifice function that can control the amount of discharged oil.

  • Patent number: 11433972
    Abstract: A bicycle gearshift is operated by imposing on the chain guide a primary displacement in the axial direction with respect to a cogset, to move the chain between the sprockets. Simultaneously with imposing on the primary displacement imposing on the chain guide a secondary displacement in the radial direction with respect to the cogset. The secondary displacement is of a greater size when the primary displacement takes place in the area of the cogset with the larger sprockets whereas it is of a smaller size when the primary displacement takes place in the area of the cogset with the smaller sprockets.
