摘要： A transmission having a shaft driven by a prime mover such as an engine or motor is provided. The transmission includes a first stationary element for supporting the shaft for rotation, and a torque transmitting device connectable to the shaft and rotatable about an axis. The torque transmitting device is actuated by a hydraulic fluid. A first passage is connected to the torque transmitting device and is in communication with the hydraulic fluid. The first passage extends radially inward from the torque transmitting device. A vent passage is located within the first stationary element and is in communication with the first passage. Rotation of the torque transmitting device about the axis separates entrained air from the fluid and urges air radially inward through the first passage and into the vent passage, thereby removing air from the hydraulic fluid and circuit.

摘要： A transmission includes an electro-hydraulic controller that includes redundancy in the hydraulic circuit that permits single fault failures to be compensated for by changing the flow path of hydraulic fluid to bypass the single fault failure. The redundancy results in the ability of the transmission to maintain full operation in all modes.

摘要： An apparatus for controlling a variator having at least one roller between two toroidal disks may include at least one actuator responsive to fluid pressure at separate high side and low side fluid inlets thereof to control torque applied by the at least one roller to the disks. First and second variator switching valves may each receive a first fluid at a first pressure and a second fluid at a second lesser pressure. The first and second variator switching valves supply the first fluid to the high side fluid inlet and the second fluid to the low side fluid inlet during two of four different operational states together defined by the variator switching valves, and supply the second fluid to the high side fluid inlet and the first fluid to the low side fluid inlet during each of the remaining two of the four different operational states.

摘要： A variator fault detection system for a continuously variable transmission is incorporated into a hydraulic control circuit that controls fluid pressure applied to a variator of the continuously variable transmission. The hydraulic control circuit for the variator includes a number of electrically-controlled shift valves and pressure control valves. Sensing devices are multiplexed to these valves to detect a number of different possible fault states relating to the variator shift valves and the variator pressure control valves.
