What kind of oil should be used in a continuously variable transmission?

[DelAlan]

Continuously variable transmissions require gear oil, and it is recommended to use gear oil with a viscosity below 150, preferably on the lower side. The specific choice depends on the model of the machine and the working environment. Introduction to Continuously Variable Transmission: A continuously variable transmission (CVT) is a type of automatic transmission in vehicles that can continuously obtain any transmission ratio within its range. It allows for optimal matching between the transmission system and the engine's operating conditions. Common types of CVTs include hydro-mechanical continuously variable transmissions, metal belt-type continuously variable transmissions (VDT-CVT), and variable-angle continuously variable transmissions. Difference between CVT and Automatic Transmission: The main difference between a CVT and a conventional automatic transmission is that the CVT eliminates the complex and bulky gear combination for transmission, instead using only two sets of pulleys for variable transmission. By changing the contact radius of the drive belt between the driving and driven pulleys, the CVT achieves variable transmission, showcasing a very ingenious design concept.
