摘要： A vehicle powertrain has an engine, a driving shaft having a passage defined therein, a driven shaft, a pump, a hydraulic fluid reservoir, and a CVT. A driving pulley of the CVT includes a fixed sheave and a movable sheave disposed on the driving shaft for rotation therewith, a spring biasing a movable sheave away from the fixed sheave, and a CVT chamber fluidly communicating with the passage of the driving shaft. The pump supplies hydraulic fluid from the reservoir to the passage in the driving shaft. The hydraulic fluid flows from the passage to the CVT chamber to create a hydraulic pressure in the CVT chamber. The hydraulic pressure in the CVT chamber biases the movable sheave toward the fixed sheave.

摘要： A driving pulley for a CVT has a shaft, a fixed sheave mounted on the shaft, a first sleeve disposed around the shaft and being operatively connected to the shaft, a movable sheave mounted on the first sleeve, a second sleeve disposed around the first sleeve and being connected to the shaft, a spring biasing the movable sheave away from the fixed sheave, and a CVT chamber having an annular cross-section. The fixed and movable sheaves are adapted to receive a belt therebetween. The CVT chamber has at least one opening adapted for fluidly communicating the CVT chamber with a hydraulic fluid reservoir. Hydraulic pressure in the CVT chamber biases the movable sheave toward the fixed sheave. The CVT chamber has an inner wall formed by the first sleeve, an outer wall formed by the second sleeve, an outer end, and an inner end formed by the movable sheave.
