Question: What is the automatic transmission service?
Answer:
There are two main differences between an automatic and a manual transmission. In a manual transmission, there is a clutch pedal and a transmission, while an automatic transmission has none. Automatic transmissions are very complex systems. Basically, a transmission is responsible for transmitting engine power to the drive wheels, whether it has a front or a rear wheel drive. The transmissions allow an engine to run at low speeds or speeds while the vehicle can travel at a wide speed range.
There are many different parts in an automatic transmission that include belts, clutches, a hydraulic system and a gear pump, but it all starts with the planetary gear set. The planetary gearset generates all the different possible gear ratios that are used by the vehicle. The planetary gear set consists of three parts: the solar system, two or more planet gears and the planetary gear and the crown wheel. The solar system is in the middle with every planetary tool that surrounds and is in contact with it. Then the crown surrounds and touches every gear on the planet. Then, from the inside out, it's the sun gear, then the gears of the planet and then the crown wheel. Each part can be one of three things: entrance, exit or stationary. It is the role it has (input, output, standstill) that determines the gear ratio of the gear set. In one of the planetary gear assemblies, the ring gear has 72 teeth and the sun gear 30 teeth; Therefore, there are thousands of possible reports. To explain how the various gears change the gears and speeds of your vehicle, I explain how your vehicle switches the first gear, the third gear (or a higher) and the reverse gear.
So that your vehicle can engage the first gear, the crown is the entry point and the planet marches the exit. The solar system remains stationary. What happens in first gear is that the crown is set in motion by moving the planetary gears around the stationary sun gear. In this case, the output (planetary gear) moves slower than the input (crown), which means that the gear ratio is reduced. Another possible scenario is to unlock the solar system and block the other two parts, which means they will be repaired. As a result, all three parts (crown wheel, planetary gear and sun gear) are moved at the same speed. This would mean the driveway is moving at the same speed as the exit and your vehicle is traveling at third or higher speed. The last scenario is to keep the planet's team stationary. Therefore, when the ring gear (input) is set in motion, the sun gear (output) is forced to move in the opposite direction, whereby the vehicle is moved backward. Another important component of automatic transmissions is the torque converter. The torque converter works like the clutch of a vehicle with manual transmission.
Torque converters transfer the necessary power to the engine to run it when the vehicle is stationary. Torque converters also provide greater torque to the wheels so that the vehicle can accelerate faster after standing. To provide this power, torque converters use transmission fluid. Gear oil is used to lubricate, clean and service all moving parts in a cold automatic transmission. Transmission oil is sent through a complex hydraulic system during a transmission. This hydraulic system is responsible for the constant supply of transmission oil to the transmission and the torque converter. The hydraulic system uses a pump, referred to as a gear pump, to deliver the pressure required to send the transmission fluid during transmission. As far as we know how an automatic transmission works, we can analyze what happens during an automatic transmission service. To keep the automatic transmission as efficient as possible, you need this service. Over time, the transmission fluid is consumed and must be replaced. It is also important to change the transmission filter and the bottom gasket.
