Chapters Questions With Correct Answers!!
How do gear sets create mechanical advantage?
They do so by having different ratios. Gears with the same number of teeth have a ratio of 1:1,
meaning that this set of gears have no mechanical advantage. They turn at the same speed
because of the same number of teeth.
Drive gear
the input gear
Driven gear
the output gear
Gear ratios can be found by comparing the number of teeth each gear has.
If the drive gear has fewer teeth than the driven gear than the gear set will have mechanical
advantage. The smaller drive gear has to rotate faster than the larger driven gear, given an
increase in output force.
All gear ratios are calculated by the formula:
driven/drive
What is overdrive?
The output gear would be turning faster than the input gear. Ex.(0.8:1)
As the gear ratio decreases the...
the output speed increases. This is what happens inside a transmission whenever the driver
selects a higher gear.
A lower gear has a...
Higher gear ratio.
Speed and torque output is the result of the...
, selected gear ratio.
Recommended shifting speed guidelines will ensure what?
Good fuel economy.
Power flow
is defined as the path in which power is transmitted through a series of components.
Power flows through what?
The entire drivetrain
What is the typical main source of mechanical power in the vehicle?
The engine.
The power that the engine creates flows from...
the crankshaft to the flywheel and to the clutch assembly.
When the clutch pedal is released...
the clutch transmits power from the flywheel to the input shaft of the transmission/transaxle.
power leaves the transmission/transaxle output shaft and flows...
to the final drive assembly. Later changes directions and flows through the axles and out to the
wheels.
When it comes to manual transmisisons...
power flows into the transmission through the input shaft. A gear on the input shaft transfers
power to a meshed gear on the countershaft. the countershaft has a number of gears that mesh
with gears on the output shaft. the gear the driver selects determines the gear ratio from the
countershaft to the output shaft. Because of the various gear sets and driver selection, the
transmission has multiple gear ratios through which power can flow.
The term transmission refers to...
layouts where the transmission sends power to the final drive assembly.
