摘要： A fan drive is disclosed which includes a planetary gear set having a first rotatable output member connected in driving relation to the fan, a second rotatable output member connected in driving communication with a hydraulic circuit, and a rotatable input member connected in driven communication with a power source, the first and second output members being connected in differentially rotatable communication with the input member. During operation, the hydraulic circuit is operable to vary the rotational speed of the second rotatable output member of the planetary gear set, to thereby vary the rotational speed of the first rotatable output member and the connected fan. According to one preferred aspect of the present invention, the input member of the hydraulic circuit is an input shaft of a hydraulic pump, the rotational speed of the pump being variable by throttling fluid flow therethrough. According to another preferred aspect of the present invention, the hydraulic circuit includes a hydraulic motor connected in driven communication with the second output member of the planetary gear set and in fluid communication with a hydraulic pump to enable power delivered to the hydraulic motor through the planetary gear set to be returned to the power source through the pump.

摘要： A split torque transmission includes a hydrostatic transmission and a mechanical transmission both being driven by an engine. The output of the hydrostatic transmission and the mechanical transmission are both selectively coupled to a machine through a final output shaft. The mechanical transmission incudes a full range high forward and reverse mechanism selectively coupled to a planetary arrangement. The planetary arrangement sums the speed of the hydrostatic transmission with the full range high forward and reverse mechanism. This arrangement provides a smooth and continuous change in the speed of the machine in both the forward and reverse directions throughout its entire speed range which is identical in both directions of travel.

摘要： A method is disclosed for providing a smooth power transition between a variable displacement pump and a variable displacement motor when a mechanical feedback is not provided. The method includes sensing and comparing the speeds of the variable displacement pump and the variable displacement motor based on known maximum volumetric displacements and reducing the rate of change of displacement of one of the variable displacement pump or the variable displacement motor when it is determined that the one is near its maximum displacement position and simultaneously initiating a change in displacement of the other thereof. The subject arrangement ensures that there is no detrimental interruptions of power during the transition of changing of displacement of one of the variable displacement pump and the variable displacement motor to changing the displacement of the other one thereof.

摘要： In many hydrostatic systems, the variable displacement pump is controlled by an operator moving a directional control valve to provide pressurized fluid to the displacement changing mechanism thereof which in turn varies the displacement responsive to the degree of pressurized fluid being directed to the displacement changing mechanism. In order to insure that the displacement of the Variable displacement pump is at the desired displacement, various forms of follow-up mechanisms have been required. These follow-up mechanisms are many times complicated and expensive to add to the hydrostatic system. In the subject arrangement, the speed of the pump input shaft and the speed of the motor output shaft is sensed (R,S) and the signals directed to a microprocessor which in turn processes the signals and directs a control signal (P) to a solenoid operated proportional valve. The solenoid operated proportional valve moves in response to the control signal and directs pressurized fluid to the displacement controller of the variable displacement pump to change the displacement thereof. Once the speed of the output shaft is achieved, the microprocessor modifies the control signal to maintain the variable displacement pump at the needed displacement position to maintain the desired speed of the output shaft to a work system. This arrangement provides an accurate control of the displacement of the variable displacement pump without the need of providing complicated follow-up mechanisms and/or servo mechanisms.

摘要： Fluid systems having modulating pressure relief valves ar normally needed in systems having clutches that require smooth engagement. It is also necessary in many systems to keep the sizes of components small to fit all of the necessary elements into a small area while simultaneously keeping the controls simple in construction for ease of manufacturing. The present modulating relief valve includes a housing having a dump valve, a load piston, and a relief valve spool concentrically disposed in the housing and adapted to control the rate of pressure rise of a fluid to a clutch and to further control the fluid flow to a torque converter while maintaining the system at a maximum pressure level. The load piston is operatively associated in a fluid flow controlling relation with each of the dump valve and the relief valve spool to control the flow of fluid to the torque converter and to simultaneously control the rate of pressure rise of the fluid in the clutch as well as limit the maximum system pressure. By having the elements of the modulating relief valve concentrically arranged and slidably disposed one within the other, the size of the modulating relief valve is reduced.

摘要： The machine may have a power system that includes a prime mover, a multiple-ratio transmission, a propulsion device, and power-system controls. The method may include propelling the machine by transmitting power from the prime mover to the propulsion device through the multiple-ratio transmission, while controlling operation of the prime mover and the multiple-ratio transmission with the power-system controls. This may include determining with the power-system controls at least one energy-efficiency estimate based at least on energy-efficiency characteristics of the prime mover and energy-efficiency characteristics of the multiple-ratio transmission. Controlling the prime mover and the multiple-ratio transmission may further include controlling a prime-mover operating speed of the prime mover and a transmission drive ratio of the multiple-ratio transmission based at least in-part on the at least one energy-efficiency estimate.
