Problems solved by technology

At present, automatic transmissions designed in Asia cannot solve this problem. Therefore, it is required that ATF oil must have anti-vibration performance, be able to maintain good friction performance, and maintain a low static friction coefficient and a high dynamic friction coefficient in the clutch.
[0004] This shows that above-mentioned existing lubricating oil composition obviously still has inconvenience and defective, and demands urgently further improving

Abstract

The present invention provides an automatic gear box lubricating oil composition, which comprises the following components: a) at least a friction improver, b) at least an antioxidant, c) at least an organic molybdate, and x) a base oil. According to the present invention, matched use of the friction improver, the antioxidant and the organic molybdate is optimized so as to change a jitter performance of an automatic gear box under a condition of a low speed or starting.

Description

technical field [0001] The invention relates to an automatic transmission lubricating oil composition, in particular to a lubricating oil composition capable of improving the jitter performance of an automatic transmission at low speed or starting, and belongs to the field of lubricating oil. Background technique [0002] Automatic transmission fluid (hereinafter referred to as ATF) is a kind of lubricating oil used in the automatic transmission system of automobiles, which mainly plays the role of lubricating and transmitting power. General automatic transmission oil needs to add viscosity index improver, extreme pressure antiwear agent, friction modifier, antioxidant, metal deactivator, oiliness agent, rust inhibitor, dispersant, detergent, antifoam agent, rubber material Various additives such as swelling agent. [0003] ATF is used in the automatic transmission system of automobiles. The main oil specifications are GM DEXRON specifications, Ford MERCON specifications an...
