NOTE

TRANSMISSION SYSTEM COMPONENTS II

Functions of the various components of the transmission system:

  1. Transmission:

   - The transmission contains gears that change the speed ratio between the engine and the wheels.

   - It allows the vehicle to accelerate, decelerate, and maintain speed at different engine RPMs.

  1. Clutch (Manual Transmission):

   - The clutch connects and disconnects the engine from the transmission.

   - It allows the driver to change gears without stalling the engine by temporarily interrupting power flow.

  1. Torque Converter (Automatic Transmission):

   - The torque converter transfers power from the engine to the transmission using fluid coupling.

   - It allows the engine to continue running while the vehicle is stationary or moving at low speeds.

  1. Gear Selector:

   - The gear selector allows the driver to choose the desired gear.

   - In manual transmissions, it's usually a gear stick. In automatic transmissions, it's a lever or buttons.

  1. Shift Linkage:

   - The shift linkage connects the gear selector to the transmission.

   - It translates the driver's input into movement of internal transmission components for gear selection.

  1. Transmission Fluid:

   - Transmission fluid lubricates and cools moving parts inside the transmission.

   - It helps transmit power and provides hydraulic pressure for gear engagement in automatic transmissions.

  1. Valve Body (Automatic Transmission):

   - The valve body is a hydraulic control unit that regulates transmission fluid flow.

   - It directs fluid to engage and disengage gears, controlling gear shifts in automatic transmissions.

EVALUATION: 1. Mention 5 components of transmission system

  1. State 2 functions each of the transmission system mentioned above.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
