How does the Hyundai Accent Tagaz automatic transmission work?
The Hyundai Accent Tagaz automatic transmission works according to the following principle:
1. Torque converter
The torque converter is the link between the engine and the gearbox. It performs several functions:
*Transmission of torque from engine to transmission
* Increased torque at low speeds
* Softening shocks and vibrations when shifting gears
2. Planetary gear
The planetary gear set is a mechanism consisting of planetary gears, a sun gear and a carrier. It is used to change gears.
* Planetary gears rotate around the sun gear and along the carrier.
* The sun gear is connected to the transmission input shaft.
* The carrier is connected to the transmission output shaft.
3. Switching elements
The shift elements determine which planetary gears will mesh with the sun gear and carrier, thereby engaging the desired gear.
* Band brakes and clutches are used to engage and disengage the corresponding planetary gears.
* The hydraulic control unit controls the switching elements, controlling the flow of hydraulic fluid.
4. Hydraulic system
The hydraulic system is used to apply fluid pressure to the band brakes, clutches and torque converter.
* The oil pump creates and maintains fluid pressure.
* The hydraulic control unit directs the fluid flow to the appropriate channels.
Gear shift process
When the driver moves the gear selector, the hydraulic control unit directs fluid flow into the appropriate channels, activating the band brakes and clutches. This causes the planetary gears to mesh with the sun gear and carrier in the correct configuration to engage the desired gear. The torque converter increases torque at low rpm, helping the vehicle move off and accelerate.
