ILM 190303 C Flashcards
What is the advantage of powershift transmissions over manual transmissions?
There is no power lost during shifting.
What types of vehicles utilize a powershift transmission?
Units used in cycling applications such as loaders.
What types of vehicles utilize an automatic transmission?
Units used in hauling applications such as dumptrucks.
What are some advantages of Planetary Transmissions?
Constantly meshed gears
Handle high torque
Lowered axial/radial thrust loads
Can be used for many gearing combinations.

What is the difference between brakes and clutches in a transmission?
Brakes lock components to the housing
Clutches lock components to each other
When a Planetary has two inputs, where does the output speed fall?
The output speed will always fall between the two inputs.
How is Neutral achieved in a Planetary Gearset?
No held member or/and
No input member
