Hydrostatic Drives Flashcards
In an open-loop hydrostatic drive system, if the speed increases at the pump, the output power at the motor will _____________.
also increase
In a fixed-displacement pump with a fixed-displacement motor, The motor has a fixed swash-plate, resulting in _______________________
constant torque at any given speed.
In a fixed-displacement pump with a fixed-displacement motor, The swashplate angle is _____________
always the same
A moveable swashplate can vary the speed of the pump, resulting in variable speed and ________________.
constant torque.
In a variable displacement pump with a fixed displacement motor. The motor has a fixed swash plate, which results in ______________.
constant torque at any given speed
When a fixed-displacement pump is used with a variable-displacement motor the design is complex. The ____________ must be controlled.
motor strike
When a variable-displacement pump is used with a variable-displacement motor the system is complex. _____________ can be adjusted independently.
Swashplates
Flow can be reversed in a system with a ________ pump and _______ motor
variable-displacement pump
variable-displacement motor
With a servo piston, any change in the piston position changes the swashplate angle, which varies the amount of __________________
oil that is sent to the motor.
A variable-displacement pump that has the charge pump mounted_______________
to the back of the housing.
A variable-displacement pump that has the charge pump. How does the speed of the charge pump compare to the speed of the main pump?
The charge pump is driven at the same speed as the main pump.
Basic open circuit hydrostatic drive has ___________ flow
bi-directional
In a hydrostatic drive, to turn left you pull backward with your ______ hand and forward with your _______ hand.
