摘要： A default mode control system for controlling a split torque transmission is disclosed. The default mode control system monitors various inputs to the control to detect an on board electrical, electronic fault or mechanical, hydraulic fault. When a fault is detected, the default mode control will recover from the default and then will limit operation of the split torque transmission based on the fault input.

摘要： A system and method for variator control employs positively directed electronic make-up and flushing relief valves for more precise torque control of a hydraulic variator, especially during torque reversal, as well as improved cold weather operation. This can improve machine response during periods of severe torque change. The ability to more tightly control variator torque allows more precise torque management algorithms for power control and engine matching purposes. Moreover, the ability to positively control venting of the hydraulic circuit for purposes of fluid cooling allows for more consistent machine response regardless of ambient temperature.

摘要： A shift mechanism for a transmission having a first and a second combination of gears is disclosed. The shift mechanism has a rod member and a hydraulic actuator operatively connected to an end of the rod member. The hydraulic actuator is configured to move the rod member between a first position at which the first combination of gears is engaged to transmit power, a second position at which the second combination of gears is engaged to transmit power, and a third position at which neither the first nor the second combination of gears is engaged to transmit power. The hydraulic actuator has a first piston slidably connected to the rod member, a second piston fixedly connected to the rod member, and a housing. The housing forms three chambers and has only two fluid conduits in communication with the three chambers.

摘要： A method and system for configuring a hydromechanical transmission having a hydraulic pump and a hydraulic motor driven by the hydraulic pump and a pressure-driven actuator employs a particular torque-pressure curve configuration to maximize torque resolution with respect to actuator pressure changes while ensuring that the curve is substantially monotonic in each dimension and at any available motor speed within a predetermined motor speed limit and any available actuator pressure within predetermined actuator pressure limits. The resultant four-dimensional association between actuator pressure, motor speed, primary power source speed and motor torque allows selection of an actuator pressure to provide a desired torque.
