摘要： A drive sheave assembly of a continuously variable transmission is provided. A fixed sheave of the assembly includes a central recess. A plurality of sheave ramps are located within the central recess. A one-way engagement collar is configured to rotate freely on an end portion of a sleeve when the sleeve rotates in a first direction and lock onto rotation of the sleeve when the sleeve rotates in a second direction. The one-way engagement collar further has a plurality of ramp pockets. A ramp member is received within each ramp pocket of the plurality of ramp pockets in the one-way engagement collar. Each ramp member is configured to engage an associated sheave ramp of the plurality of sheave ramps in the central recess of the fixed sheave and move the one-way engagement collar axially to engage a side of a belt when the sleeve rotates in the second direction.

摘要： A CVT clutch is provided. A fixed sheave of the CVT clutch is statically mounted on an end of the post. A movable sheave assembly is dynamically mounted on the post. The movable sheave includes a recess cavity that is defined by a movable sheave housing. A spider is statically mounted on the post within the recess cavity of the movable sheave assembly. At least one interchangeable ramp is positioned within the recess cavity so that at least one space is provided between the at least one interchangeable ramp and a sheave face of the movable sheave housing. An engagement member is positioned to engage an associated interchangeable ramp and the spider. A main bias member is configured to assert a bias force on the spider and cover to position each engagement member at a select location on the associated interchangeable ramp when a countering force is not present.

摘要： A multi-component idler or pulley that may be used with a belt and pulley system of an automobile is disclosed. The multi-component idler may have an external idler housing coupled to a mounting hub that is designed to be connected to a mounting surface of the belt and pulley system. The axial position of the external idler housing may be adjustable relative to the mounting hub using a threaded engagement or a plurality of shims between the components. The external idler housing and the mounting hub may be fastened to each other by bolts once their positions are adjusted relative to each other. Different types of external idler housing may also be used with the mounting hub. In this way, the serpentine belt of the belt and pulley system may be adjusted based on the user's needs.

摘要： Provided are a support structure whereby the load on a motor drive shaft or bearing can be reduced, and an industrial machine. The support structure according to an embodiment of the present invention comprises a bearing (112) positioned between a motor (102) and a drive pulley (104), and a bearing holder (114) provided to the motor (102). An inner race (120) of the bearing (112) is fixed to the drive pulley (104) so as to be incapable of sliding in the axial direction of a drive shaft (102S), and an outer race (122) of the bearing (112) is allowed to move in the axial direction between the bearing holder (114) and the drive pulley (104).

摘要： A Cone with two Rotatable Raised Surfaces which can allow for the construction of a “Cone with One Torque Transmitting Member” for which the teeth of the Torque Transmitting Member of said “Cone with One Torque Transmitting Member” have a base. One of said two Rotatable Raised Surfaces is used to raise the Leveling Extension of said Torque Transmitting Member from a base surface, which is beneath the base of said Torque Transmitting Member, to a raised surface, which is level with the top surface of said bases of said teeth of said Torque Transmitting Member; such that the top-surface of said Leveling Extension can provide a resting place for the teeth of the Transmission Belt used with said “Cone with One Torque Transmitting Member”.

摘要： Methods, systems, and vehicles that control the temperature of a device included in the vehicle are presented herein. The temperature of the device is controlled by ventilating the device with drivetrain air, such as transmission cooling air. In some embodiments, the device is at a greater temperature than the drivetrain air, which cools the device. In other embodiments, the device is at a lesser temperature than the drivetrain air, which heats the device. The drivetrain air is provided to the device through an exhaust duct coupled to the vehicle's transmission. The drivetrain exhaust air is preferably circulated by the transmission. The transmission may be a continuously variable transmission. The device may be an oxygen sensor that is coupled to an engine exhaust pipe. The oxygen sensor is thermally coupled to the engine exhaust and the engine exhaust pipe, which are at greater temperatures than the transmission exhaust air.

摘要： 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.
