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.

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.

An isolating decoupler comprising a shaft, a pulley journalled to the shaft on at least one bearing, a one-way clutch engaged with the shaft, a torsion spring engaged between the one-way clutch and the pulley, the shaft comprises an inner race of the at least one bearing, and the torsion spring having an end welded to the one-way clutch and having another end welded to the pulley.

A drive sheave assembly of a continuously variable transmission is provided that includes a post, a fixed sheave, a movable sheave assembly, a sleeve and an engine braking assembly. The engine braking assembly includes an axial activation member, a one-way engagement member and a flange. The axial activation member is statically mounted within a central recess of the fixed sheave. The axial activation member is movably connected with the one-way engagement member. A central passage of the one-way engagement member is configured to engage a portion of the sleeve. The flange is coupled to the one-way engagement member to selectively engage a side of an endlessly looped member with axial movement of the one-way engagement member during an engine braking condition.

Embodiments of the present disclosure describe a drive pulley for a continuously variable transmission including a stationary sheave with a stationary shaft, a movable sheave axially movable relative to the stationary sheave and in contact with the stationary shaft; a spider in contact with at least the moveable sheave and stationary shaft; a spring member, biasing the movable sheave axially away from the stationary sheave; at least one centrifugal actuator including an arm pivotally connected to one of the movable sheave and the spider, the arm pivoting away from the one of the movable sheave and the spider as a speed of rotation of the drive pulley increases, the arm pushing against another one of the movable sheave and the spider as the arm pivots away from the one of the movable sheave and the spider, thereby moving the movable sheave axially toward the stationary sheave, the at least one centrifugal actuator being disposed radially outward of the stationary sheave shaft; and a torque transfer assembly operatively connected to at least one of the spider and the movable sheave, the torque transfer assembly transferring torque between the spider and the movable sheave, the torque transfer assembly including, a torque bearing assembly and at least one roller assembly, positioned on a helixed torque pin, the torque pin connected to the spider; wherein as the roller assembly wears, the at least one roller assembly tracks along a helixed path of the torque pin in a distal direction from the bearing assembly.

A variable pitch pulley includes a rotary shaft, a fixed sheave fixed to the rotary shaft, and a moving sheave forming a belt groove with the fixed sheave. The moving sheave includes an inner sheave and an outer sheave radially stacked on the inner sheave. The pitch pulley further includes a moving sheave-positing unit determining relative positions of the inner and outer sheaves. The inner and outer sheaves are simultaneously moved in an axial direction of the rotary shaft in a first moving mode, and only the outer sheave is moved in the axial direction in a second moving mode.
