Description

technical field

[0001] The invention relates to the technical field of lubricating oil, in particular to a multi-vehicle universal continuously variable transmission oil and a preparation method thereof. Background technique

[0002] In the field of traditional multi-speed automatic transmissions, we have seen a trend towards light weight and an increase in the number of gears. OEMs have also introduced new hardware, including dual-clutch transmissions (DCT) and continuously variable transmissions (CVT). CVTs offer the many benefits of continuously and seamlessly selecting the optimum ratio for the engine as driving conditions change, without the fixed ratio limitations of multi-stage gearboxes. The flexibility afforded by this variable ratio (within the minimum and maximum limits of the CVT design) allows the engine to operate at peak efficiency with uninterrupted torque transfer to the drive wheels. This ability to optimize engine operation gives CVTs an advantage over o...
