Study Notes
Transmission Basics
- Maximum speed is achieved with a 1:1 gear ratio.
- Truck transmissions can be either automatic or manual.
Transmission Structure
- Transmissions consist of an assembly of gears and shafts that convey power from the engine through the driveline to the axles, wheels, and tires.
- The countershaft gear and reverse idler gear rotate together.
Gear Ratio
- Gear ratios describe the interaction of driving gears on driven gears, indicating the relationship between input and output.
Transmission Types
- In sliding gear transmissions, output shaft gears move along their shaft.
- The input and output shafts are not parallel.
Features and Functionality
- Not all transmissions with range control include a splitter.
- A five-speed main transmission equipped with range control and a splitter can provide a total of 13 speeds.
- Utilizing multiple countershafts enhances the durability and lifespan of the transmission.
