摘要： This invention relates to controlling the speed ratio of a Continuous Variable Transmission with a hydraulic method. The Ball Planetary CVT design is adapted with a mechanical and hydraulic addition. The carrier of the ball-type variator is supported by hydraulic actuators. The result is that the speed ratio is controlled by both a set speed ratio and the torque flowing through the CVT. Subsequently, torque peaks are avoided and controllability of the CVT is increased.

摘要： A method and apparatus for controlling the mass flow rate of a positive displacement expander (44) comprises pumping (54) a working fluid to a heat exchanger (56) to convert the fluid into a working vapor. At least a portion of the working vapor is stored in an accumulator (58) connected to the heat exchanger. At least a portion of the working vapor stored in the accumulator is selectively released into a positive displacement expander via a pulse width modulated valve (64) to increase the efficiency of the expander.

摘要： A system and a method for monitoring a lubricant in a transmission are provided. The system comprises a first speed sensor, a temperature sensor, and a processing unit. The first speed sensor is positioned adjacent a first clutch, which forms a portion of the transmission. The first speed sensor is configured to detect a rotational difference between portions of the first clutch. The temperature sensor is disposed within the transmission. The temperature sensor is configured to measure a temperature of the lubricant. The processing unit is in communication with the first speed sensor and the temperature sensor. In response to information from the first speed sensor and the temperature sensor, the processing unit determines a condition of the lubricant used in the transmission.
