Automatic transmission device Hyundai Solaris
The Hyundai Solaris automatic transmission is a 4-speed or 6-speed automatic transmission that provides smooth shifting and improved fuel economy.
Automatic transmission components
* The hydraulic transformer converts engine speed into the torque required to move the vehicle.
* A planetary gearbox uses gears rotating around a central shaft to change the gear ratio.
* The hydraulic unit controls gear shifting by directing fluid from the transmission to the appropriate parts of the planetary gearbox.
* Hydraulic clutches lock and unlock the necessary gears for gear changes.
* Transmission control unit (TCU) is an electronic unit that controls the operation of the transmission using signals from various sensors.
Operating principle
The Hyundai Solaris automatic transmission works as follows:
* Gear selection: The driver selects the desired gear lever position (P, R, N, D).
* Transformation: The hydraulic transformer converts engine speed into torque, which is then sent to the planetary gearbox.
* Shifting: The hydraulic unit directs fluid to the respective clutches to lock and unlock the gears, resulting in a change in gear ratio.
* Control: The TCU monitors various parameters such as engine speed, throttle position and vehicle speed and adjusts gear changes accordingly.
Operating mode
The Hyundai Solaris automatic transmission has several operating modes:
* D (Drive): Standard forward driving mode that automatically changes gears.
* N (Neutral): Neutral gear in which the transmission is not connected to the engine.
* R (Reverse): Reverse.
* P (Park): A parking gear that mechanically locks the transmission and applies the parking brake.
