Robotic gearbox (manual transmission)
* Consists of a conventional manual gearbox controlled by drives and an electronic control unit.
*Uses the clutch to connect and disconnect the engine from the transmission.
* Automates clutch control and gear shifting.
Automatic transmission (AT)
* Consists of a torque converter and a planetary gearbox.
* The torque converter replaces the clutch and transfers torque from the engine to the transmission.
* Planetary gearbox ensures gear shifting without interrupting the power flow.
Main differences:
* Clutch: Manual transmission uses a dry or wet clutch, while automatic transmission uses a torque converter.
* Gear shifting: Manual transmission shifts gears mechanically, while automatic transmission uses hydraulic or electronic mechanisms.
* Shift mode: Manual transmission can switch to manual mode, but automatic transmission cannot.
* Efficiency: Automatic transmissions are generally more fuel efficient than manual transmissions, especially at low speeds.
* Dynamics: Manual transmission provides faster and sharper gear changes than automatic transmission.
* Reliability: Manual transmission is considered more reliable than automatic transmission due to its simpler design.
* Cost: Manual transmissions are usually cheaper to produce than automatic transmissions.
Advantages of manual transmission:
*Higher fuel efficiency
* Faster and sharper gear changes
* Better dynamics
* Lower cost
Advantages of automatic transmission:
*Smoother gear shifting
* Better driving comfort
*Easier to operate
*Higher fuel efficiency at low speeds
