Study Notes
Clutch and Transmission Fundamentals
- Clutch slippage is not more noticeable during deceleration.
- Pressure plate assemblies include essential components but do not have a release fork, return springs, and pivot.
- The diaphragm spring is also referred to as the Bellville spring.
- Modern friction discs often incorporate cushion springs for smoother clutch engagement.
- Common materials for modern clutch friction include cotton, paper, and wire.
Clutch Performance and Issues
- Clutch chatter arises from oil contamination leading to glazing.
- Drag is the reason a vehicle may move while starting the engine with the pedal disengaged.
- In a hydraulic clutch system, pressing the clutch pedal results in the master cylinder piston moving.
Synchronizer Assemblies
- A typical synchronizer assembly has various true characteristics, with the exception that the sleeve rotates on the hub.
- The blocking ring's cone functions as a cone-clutch during gear changes.
- Synchronizers ensure that the output shaft and speed gear rotate at the same speed.
Gear Types and Shifting Problems
- Spur gears are known to develop gear whine at high rotational speeds.
- Poorly adjusted shift linkages can lead to gear clash, hard shifting, or the gear jumping out of position.
- A broken or worn engine or transaxle mount can negatively affect shifting performance.
- Hard shifting issues in manual transmissions may arise from various factors, but a worn pilot bearing is not among them.
