Description

Multi-vehicle type universal stepless transmission oil and preparation method thereof
Technical Field
The invention relates to the technical field of lubricating oil, in particular to multi-vehicle type universal stepless transmission oil and a preparation method thereof.
Background
In the field of conventional multi-speed automatic transmissions, we have seen a trend towards lighter weights and an increase in the number of gears. OEM manufacturers have also introduced new hardware, including Dual Clutch Transmissions (DCTs) and Continuously Variable Transmissions (CVTs). The continuously variable transmission has the advantage that the optimum ratio can be selected seamlessly for the engine continuously as driving conditions change, without the fixed ratio limitations of a multi-stage gear transmission. The flexibility afforded by this variable ratio (within the minimum and maximum limits of the continuously variable transmission design) allows the engine to operate at peak efficiency without torque transfer to the drive wheels being interrupted. This ability to optimize engine operation provides a continuously variable transmission that is more advantageous in terms of overall vehicle fuel efficiency than other transmission designs.
The core of the stepless speed changing box is a speed changing box with two pulleys, each pulley is composed of two conical adjustable belt wheels, and a thrust steel belt or a steel chain is arranged around each belt wheel in a surrounding mode. Torque is transmitted by steel-steel friction generated between the pulley and the steel belt or chain. It is also necessary to minimize wear between these components when the steel-to-steel friction is high. Continuously Variable Transmission Fluid (CVTF) has high steel-to-steel friction, enabling the use of continuously variable transmissions at the highest torque.
Conventional automatic transmission fluids provide low steel-to-steel friction that can cause drive belt slip, wear, and severe damage to pulleys and steel belts or chains. Shear stability is more important for infinitely variable transmission fluids than for conventional automatic transmission fluids because of the high pressure pump used in infinitely variable transmission applications. In addition to these specific requirements, infinitely variable transmission fluids must also provide excellent wear protection, especially to control component fatigue and sliding wear. Continuously variable transmission fluids must also have longer anti-shudder durability to ensure exceptionally slippery clutching operation, be used in some designs to achieve fuel economy, and not reduce steel-to-steel friction. While at the same time providing good antioxidant stability, air release and paper-iron friction.
