Chapter 3 Homework Clutch Flashcards
When discussing where a clutch disc is normally mounted,
Technician A says that it is bolted to the flywheel.
Technician B says that it is splined to the transmission input shaft.
Who is correct?
B only
Which of the following statements about the torsional springs in a clutch disc are not true?
a. They dampen vibrations coming from the transmission and drive shaft.
b. They may be tuned to a particular engine and driveline.
c. They cushion the sudden load on the disc when it is quickly engaged.
d. They are only found on flexible clutch discs.
They dampen vibrations coming from the transmission and drive shaft.
When discussing the purpose of the flywheel,
Technician A says that it serves as a heat sink for the clutch disc.
Technician B says that it serves as a vibration dampener for the engine.
Who is correct?
Both A and B
When discussing the operation of the clutch assembly,
Technician A says that when the pedal is depressed, the release bearing is pushed against the release fingers of the pressure plate, which releases the plate’s pressure on the clutch disc.
Technician B says that the clutch disc is pressed against the flywheel by the pressure plate.
Who is correct?
Both A and B
When discussing the major components of a hydraulic clutch linkage,
Technician A says that the master cylinder for the car’s brakes is also used for the clutch.
Technician B says that the slave cylinder is directly connected to the clutch pedal and increases hydraulic pressure as the pedal is depressed.
Who is correct?
Neither A nor B
When discussing release bearings,
Technician A says that constant running release bearings are used with hydraulically controlled clutches.
Technician B says that the release bearing moves the pressure plate fingers to disengage the clutch.
Who is correct?
Both A and B
When discussing the dual-clutch systems,
Technician A says that all dual-clutch systems use wet clutches.
Technician B says that dual-clutch systems require the use of a clutch pedal.
Who is correct?
Neither A nor B
When discussing pilot bearings or bushings,
Technician A says that they are often eliminated in front-wheel drive vehicles.
Technician B says that they serve as a low-friction pivot point for the clutch linkage.
Who is correct?
A only
While discussing hydraulic clutch systems,
Technician A says the slave cylinder responds directly to the clutch pedal and sends hydraulic fluid to the clutch master cylinder.
Technician B says the clutch delay valve between the master and slave cylinder allows for immediate clutch release.
Who is correct?
Neither A nor B
While discussing semicentrifugal pressure plates,
Technician A says they alter the holding force of the clutch assembly in response to engine speed.
Technician B says they require high pedal effort at low engine speeds.
Who is correct?
A only
