To provide a displacement detection device and a continuously variable transmission that directly detect the position of the movable sheave. A displacement detection device includes a magnet that forms a magnetic field, a movable sheave that is rotated in a rotational direction and displaced in a direction perpendicular to the rotational direction and that is a measuring object having a concave portion (or a protrusion) on the circumferential surface, and a sensor disposed between the magnet and the circumferential surface of the movable sheave and detecting a change in magnetic flux density due to the displacement of the movable sheave in the magnetic field formed by the magnet and induced to the concave portion (or the protrusion).

A system and method for a bicycle transmission. Specifically, a bicycle transmission having a housing with a first shaft passing therethrough and a set of two cones in opposing parallel alignment disposed within the housing. The first cone engaged about the first shaft, the second cone engaged about a second shaft parallel to the first shaft, the second shaft structured and arranged to have at least a proximal position and a distal position relative to the first shaft. A driver is disposed generally normally about one of the two cones and passing therebetween, the driver structured and arranged to engaging a portion of the first cone with a portion of the second cone when the second cone is in the proximal position. A driver mover structured and arranged to move the driver between the cones when the second cone is in the distal position; and a transfer element joined to an end of the second shaft.

Methods that can be used to limit the maximum shaft/spline rpm (speed) at which axial position changing of a variator mounted on it is performed to a maximum axial position changing rpm value for all variator mounted shafts/splines of a CVT, while still allowing a safe driving experience and also allowing the driver to use the full power of the engine when needed.

A fast indexing mechanism that can be used to quickly and accurately change the axial position of a cone of a CVT. Said indexing mechanism comprises of a Rotation Providing Mechanism that is powered by springs that are tensioned by a pneumatic/hydraulic actuator (see FIGS. 41 and 42), a Rotation to Linear Converting Mover Mechanism (see FIG. 44), and an Indexing and Clutching Mechanism (see FIG. 43).

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.

A CVT 6 (FIG. 9) comprising of two substantially identical CVT 4's. Each CVT 4 comprises of two cones that are coupled by a transmission belt. The driving cones of the CVT 4's are mounted on a common shaft, and the driven cones of the CVT 4's are mounted on a common shaft. For each CVT 4, one of its cones is mounted on its shaft using an adjuster, which uses an indexing mechanism, that can lock or release the rotational position of its cone relative to the shaft it is mounted. Each CVT 4 has a tense side tensioning/support pulley and a slack side tensioning/support pulley (FIG. 6) which can provide and remove slack as needed to allow for axial position changing of a cone for all operating conditions of their CVT without breaking/excessively stretching a transmission belt.
