Problems solved by technology

However, the promotion of pure electric vehicles is not only a revolutionary event for automobile manufacturers, but also a big challenge for automobile lubrication
Compared with traditional cars, pure electric vehicles reduce the number of engine lubrication links, but the lubrication of gearboxes is much stricter than traditional gearboxes
[0004] Compared with pure electric vehicles, the volume and weight of traditional automotive gearboxes are too large, and their transmission efficiency is not good, and there are great difficulties in the installation design and matching of pure electric vehicles, so pure electric vehicle gearboxes cannot be simple. Replaced by traditional car gearbox

Abstract

The invention relates to the field of lubricating oil and in particular discloses a composition used for pure electric vehicle transmission oil and a preparation method thereof as well as transmission oil containing the composition and a preparation method thereof. The composition used for the pure electric vehicle transmission oil is prepared from the following components in parts by weight: 5-25 parts of a viscosity index improver, 0.5-1.5 parts of a purification dispersant, 2-8 parts of an antioxidant, 0.05-0.5 part of a corrosion inhibitor, 1.5-5.0 parts of an antiwear agent, 0.5-3.0 parts of a friction modifier, 0.5-1.5 parts of an anti-aging agent, 0.01-0.1 part of an anti-foaming agent and the balance of base oil A, wherein the total parts by weight of the components is 100 parts. The composition used for the pure electric vehicle transmission oil and the transmission oil containing the composition can provide excellent oxidation stability, excellent antifoaming property, excellent antiwear corrosion-resistant property, good material adaptability with a pure electric vehicle transmission and copper protection performance under high voltage and high current conditions.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a composition for transmission oil of pure electric vehicles and a preparation method thereof, as well as a transmission oil containing the composition and a preparation method thereof. Background technique [0002] A pure electric vehicle refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to the smaller impact on the environment than traditional vehicles, the development prospects of pure electric vehicles are widely optimistic. From high-end electric vehicles representing Tesla entering China, to the advent of electric vehicles such as Song and Tang under the self-owned brand BYD, to the establishment and promotion of electric vehicle brands such as Zhidou, the research on pure electric vehicles has achieved rapid development in recent years . In addition, ...
