Clutches And Brakes KC7 Flashcards
What is the function of the clutch in a manual transmission? How does the clutch actually work?
The clutch is a mechanism to disconnect the flow of power to the transmission without turning the engine off.
The clutch consists of a disk with high-friction material that sits on the flywheel that rotates with the flywheel when an external force is applied due to friction. The clutch disk is connected to the drive shaft which allows the power from the engine to be transmitted to the transmission system when engaged.
What is the function of the diaphragm spring? How is it connected to the clutch pedal?
The function of the diaphragm spring is to disengage the clutch by moving the pressure disk away from the friction disk. This, power flow will discontinue to the transmission.
The diaphragm is connected to the clutch pedal by a hydraulic system.
In an uphill start, when you partially release the clutch, what happens?
When you partially release the clutch, you will feel the “clutch bite”. This partially released clutch acts like a break.
What are the main components of a typical car’s braking system?
- Hydraulic Brake Fluid
- Caliper
- Break Pads
- Rotors
How do car breaks work?
Hydraulic break fluid flows from the master cylinder through lines to the caliper which squeezed the break pad against the rotors creating friction which slows and stops your vehicle.
When you take your car in for a check up, what about the breaks is being evaluated?
The break pads and rotors are being checked for wear. Additionally, break pads can become loose, cracked, or broken and disk rotors can become grooved, pitted, or warped from the continual heat of breaking.
Clutch
Provides an interruptible connection between two rotating shafts.
Brake
Provides an interruptible connection between one rotating element and a nonrotating ground plane.
