摘要： An integrated power system for use with a gas turbine engine is provided for driving and steering a tracked vehicle under the control of the vehicle's operator. The system includes a multispeed transmission for transmitting power from a free power turbine, included in the gas turbine engine, to combining planetary gear systems driving the vehicle, elements of the combining planetary gear systems also being driven by a variable displacement hydraulic steering motor. The transmission is connected to a direct displacement pump for supplying fluid under pressure to the steering motor and to an accumulator which stores and releases energy to the pump to reduce shock to the system as the speed ratio of the transmission is changed in response to the speed of the free power turbine. A control system, responsive to the vehicle's operator, determines operation of the hydraulic steering motor to effect steering as well as controlling the power output of the gas turbine engine. The control system, in response to the vehicle's operator, also controls pivot steering as well as movement of the vehicle in forward or reverse directions. An overrunning clutch interconnects the free power turbine to the gas producer whenever the turbine tries to exceed the speed of the gas producer.

摘要： A hydraulic motor drive system controls the pressure of the hydraulic fluid delivered to a motor by a variable pressure source to control the rotation of a high inertial load rotary member driven by the motor. The speed of the motor and/or rotary component is monitored and changes in the speed are controlled by changing the pressure of the hydraulic fluid delivered to the motor.

摘要： A hydraulic transmission comprising a variable displacement pump and motor, at least one having cylinders having valves which are controllable on each cycle of cylinder working volume to determine the net displacement of working fluid by the cylinder. The transmission has a valve control module which determines a displacement of the pump and the motor by specifying a displacement demand. The pump and/or motor valve control module determine the frequency of intensity peaks in the frequency spectrum of the pattern of cylinders carrying out active and inactive cycles of cylinder working volume using a first procedure and, if these will fall within disallowed frequency bands including the resonant frequency of components with which the transmission is in mechanical communication, the displacement demand, or another input, is periodically modified to suppress generation of those frequencies. The hydraulic transmission is useful for example in a wind turbine generator, or a vehicle.

The filter housing can be secured to the center section by the check valves, which also may include high pressure bleeds to allow hydraulic fluid to flow from the hydraulic circuit. A shield may be located between the high pressure bleeds and the filter to prevent damage by the fluid to the filter as it exits the bleeds. The filter housing can also include integral projections on which a bypass actuation member can be mounted.
