Automatic transmission (automatic transmission) Toyota Town Ace
Working principle:
The Toyota Town Ace automatic transmission is a planetary automatic transmission that uses a series of planetary gears and a hydraulic torque converter to automatically change gears.
Components:
* Hydraulic Torque Converter: A device that transfers power from the engine to the transmission, providing smooth starting and torque transmission.
* Planetary gears: A system of gears that provide different gear ratios.
* Clutches and bands: Devices that lock or unlock the various planetary gears to change gears.
*Hydraulic control unit: The brain of the transmission that controls gear shifting based on various inputs.
Operating modes:
* P (Park): The transmission is locked and does not transmit torque.
* R (Reverse): The transmission shifts to reverse.
* N (Neutral): The transmission is disabled and does not transmit torque.
* D (Drive): The transmission switches to normal driving mode, automatically changing gears depending on load and engine speed.
* L (Low): The transmission shifts to a lower gear for higher torque when off-roading or towing.
Gear shift:
*Town Ace automatic transmission changes gears automatically based on input information such as:
* Motor speed
* Engine load
* Throttle position
* Vehicle speed
* The hydraulic control unit processes this information and adjusts hydraulic pressure to engage or disengage the appropriate clutches and bands, shifting gears smoothly.
Peculiarities:
*Smooth gear shifting
* Automatic gear selection
* Special modes for off-road and towing
* Ease of driving, especially in city traffic
