The durability of gearbox gears is usually high, and under normal use and maintenance conditions, their lifespan can reach more than 20 years or a mileage of over 500000 kilometers.
The durability of gearbox gears is influenced by various factors, including material quality, manufacturing process, usage conditions, and maintenance. Specifically:
Materials and Manufacturing Process: Transmission gears are usually made of high-strength alloy steel or carburized steel, and undergo processes such as carburizing, quenching, and low-temperature tempering to achieve a tensile strength of over 500 megapascals, ensuring their excellent mechanical properties and durability.
Normal operating conditions: Under normal operating conditions, the transmission gears can withstand the torque and speed changes output by the engine, meeting the power transmission needs of the vehicle under different operating conditions. If the gearbox is subjected to severe impact or collision, or if maintenance is neglected for a long time, it may cause gear damage.
Maintenance and upkeep: Regularly checking the level and quality of the transmission oil, and replacing the transmission oil in a timely manner can ensure that the gears receive sufficient lubrication, reduce wear, and extend their service life.
Dual clutch transmission: Taking the dual clutch transmission as an example, its gears are usually made of materials such as carbon steel and alloy steel, with a designed service life of about 20 years and a driving range of up to 500000 kilometers. The wet dual clutch is cooled by oil, and the service life of the friction part is relatively long.
