TRANSMISSION SYSTEM
Chief function of the device is to receive power at one torque and
angular velocity and to deliver it at another torque and the corresponding
angular velocity.
REQUIREMENTS OF TRANSMISSION SYSTEM
1. To provide for disconnecting the engine from the driving wheels.
2. When the engine is running, to enable the connection to the driving
wheels to be made smoothly and without shock.
3. To enable the leverage between the engine and driving wheels to be
varied.
4. It must reduce the drive-line speed from that of the engine to that of
the driving wheels in a ratio of somewhere between about 3:1 and 10:1
or more, according to the relative size of engine and weight of vehicle.
5. Turn the drive, if necessary, through 90° or perhaps otherwise re-align
it.
6. Enable the driving wheels to rotate at different speeds.
7. Provide for relative movement between the engine and driving wheels.
