    Abstract: A Torque Transmitting Member for a Cone with One Torque Transmitting Member that can be used to construct Non-friction Dependent CVT's that can be used with a Transmission Belt for which the teeth of said Transmission Belt are shaped below the belt of said Transmission Belt. In order to provide a Level Resting Place for said Transmission Belt on the conical (sloped) surfaces of its Cone, which are surfaces that are not covered by said Torque Transmitting Member or a Non-Torque Transmitting Member, said Torque Transmitting Member and said Non-Torque Transmitting Member each have a Leveling Extension. The Leveling Extension of said Torque Transmitting Member can enter and exit said Non-Torque Transmitting Member as required; and the Leveling Extension of said Non-Torque Transmitting Member can enter and exit said Torque Transmitting Member as required.

    Abstract: A vehicle includes an engine, a continuously variable transmission including an endless belt to output a power from the engine, and a transmission to which the power from the continuously variable transmission is transmitted. If the vehicle travel speed is not smaller than a first threshold value and an accelerator opening degree is not smaller than a second threshold value, a controller determines that the continuously variable transmission is being used in a belt high-load situation. If a travel distance in the belt high-load situation is not smaller than a third threshold value, the controller determines that the endless belt is deteriorated or deterioration thereof is in an advanced stage, and a deterioration message about the endless belt is displayed on a display based on an instruction from the controller. A situation in which a speed changing ratio of the continuously variable transmission is not greater than a fourth threshold value may be determined as the belt high-load situation.

    Abstract: A plate link chain includes a chain running direction, an axial direction, a radial direction, a plate link, and a rocker pin pair. Each rocker pin has a plate link side contact surface, a rolling surface, and axially opposite end faces. The end faces are inclined axially inwards from radially outside to radially inside, aligned transversely to the axial direction, and arranged for force transmitting contact with a conical pulley pair. The end faces have respective curvatures having a first curvature portion defined by a radial radius about a first axis parallel to the chain running direction, and a second curvature portion defined by an azimuthal radius about a second axis parallel to the radial direction. A magnitude of the radial radius increases from radially outside to radially central, or a magnitude of the azimuthal radius increases from forward to central with respect to the chain running direction.

    Abstract: A snowmobile includes a frame, a tunnel, a seat, an endless track, at least one ski, a handlebar, a cowling defining an engine compartment, an engine, a continuously variable transmission (CVT) operatively connecting the engine to the endless track, and a pulley guard assembly disposed over at least a portion of the CVT. The CVT includes a primary pulley, a secondary pulley, and an endless flexible member operatively connecting the primary pulley to the secondary pulley. The pulley guard assembly is disposed between the CVT and a lateral side of the cowling, and defines an air inlet. The air inlet fluidly communicates with a space defined between the pulley guard assembly and the lateral side. In some implementations, the cowling defines an air inlet. In some implementations, an air duct fluidly connects the air inlet of the cowling to the air inlet of the pulley guard assembly.

    Abstract: A variable drive system to drive an accessory drive of a machine is disclosed. The variable drive system may include a first variable pulley to be mechanically coupled to the accessory drive and an engine output of an engine. The variable drive system may include a second variable pulley to be mechanically coupled to a flywheel. The variable drive system may include a drive element to rotate, according to a clutch system, about the first variable pulley and the second variable pulley to at least one of: drive the second variable pulley to charge the flywheel with kinetic energy or drive the first variable pulley via kinetic energy from the flywheel.
