Problems solved by technology

[0006] At present, there are few reports and information disclosures on lubricating oil specially used in the central hydraulic system of dry dual clutch gearboxes
Moreover, the gearbox is a whole. If there is oil leakage or the wrong type is added by the maintenance worker, the gearbox oil with the characteristics of gear oil is different from the oil system of the central hydraulic system, which will cause serious damage to the gearbox or even scrap it.

Abstract

The invention discloses gear oil and a preparation method thereof. The gear oil comprises the following components according to parts by weight: base oil, a viscosity index improver, a pour point depressant, an antirust agent, an anti-wear additive, a high-temperature antioxidant, a friction improver and a detergent dispersant. The gear oil has the performance of gearbox gear oil and the characteristics of central hydraulic system oil at the same time, lubricating oil used by two oil supply systems of the dry type double clutch is combined into one, the risk that two different kinds of oil pollute each other is avoided, and the trouble of stock of a repair factory is simplified.

Description

technical field [0001] The invention relates to the technical field of lubricant and its preparation, in particular to gear oil and its preparation method. Background technique [0002] The gearbox is the brain of the car's power. It can cut off the engine power instantly, transmit the engine torque, reduce the speed and increase the torque, realize different speed ratio transmission and reverse driving. The development trend of automobiles puts forward higher requirements for power, economy, emission and maneuverability. As the gearbox is one of the most important parts of the transmission system, how to achieve these higher requirements has always been the goal of the gearbox designers. However, the traditional automatic transmission structure has a large loss of power, and a considerable part of the power of the engine is swallowed up during the power transmission process of the transmission. Compared with manual transmission, automatic transmission will increase fuel c...
