Summary of "Transmission Dog Clutch Working"
Dog Clutch in a Modern Constant Mesh Manual Transmission
The video explains the function and operation of a dog clutch within a modern constant mesh manual transmission system. Below are the key technological concepts covered:
Dog Clutch Role
- Dog clutches, also known as dog teeth, are used to select gear ratios by locking the transmission’s output shaft to a specific gear set.
Gear Engagement
- When disengaged, all gears spin freely around the output shaft, which corresponds to neutral.
- Engaging a dog clutch connects the output shaft to a gear, causing the shaft to rotate at the gear’s speed and thus setting the gear ratio.
Mechanism
- The dog clutch is a sliding selector with teeth that engage splines on the output shaft.
- It moves back and forth to engage or disengage gears.
Control System
- Movement of the dog clutch is controlled by a selector fork linked to the gear lever.
- The fork is fixed and attached to a collar bearing on the selector.
Selector Design
- The selector is symmetric and slides between two gears.
- Synchronizer teeth on each side lock either gear to the shaft.
Non-slip Coupling
Unlike a foot-operated clutch, a dog clutch provides a direct, non-slip connection and is not designed for slipping.
