Definitions
- a vehicle propulsion system generally operates at high rotational speeds. It is therefore necessary for the lubricating composition used to retain good performance and good properties, even when it is subjected to high rotational speeds.
- the polyorganosiloxane (s) are chosen from polyalkylsiloxanes, where the alkyl groups typically have from 1 to 24 carbon atoms, preferably from 1 to 12 carbon atoms, preferably from 1 to 6 atoms. of carbon.
- the polyorganosiloxane (s) used in the invention are chosen from polydimethylsiloxanes.
- the polyorganosiloxane (s) are used in the invention as a mixture with silica, typically at a content such that the silica content ranges from 0.001 to 1.5% by weight, preferably from 0.002 to 1% by weight, relative to weight total of the lubricating composition (obtained after adding the polyorganosiloxane (s) and the silica).
- composition suitable for the invention comprises at least one additional additive chosen from friction modifiers, viscosity index modifiers, detergents, extreme pressure additives, dispersants, antioxidants, point-d depressants. flow, defoamers and mixtures thereof.
- Antioxidant additives act in particular as radical inhibitors or destroyers of hydroperoxides.
- antioxidant additives commonly used, there may be mentioned antioxidant additives of phenolic type, antioxidant additives of amine type, phosphosulfurized antioxidant additives. Some of these antioxidant additives, for example phosphosulfurized antioxidant additives, can generate ash.
- the phenolic antioxidant additives can be ash-free or in the form of neutral or basic metal salts.
- Sulfurized alkyl phenols or their alkali and alkaline earth metal salts can also be used as antioxidant additives.
- a lubricating composition used according to the invention can comprise from 0.5 to 2% by weight of at least one antioxidant additive, relative to the total weight of the composition.
- a lubricating composition used according to the invention is free from an antioxidant additive of aromatic amine type or of sterically hindered phenol type.
- the detergent additives are preferably chosen from alkali metal or alkaline earth metal salts of carboxylic acids, sulphonates, salicylates, naphthenates, as well as salts of phenates.
- the alkali metals and alkaline earth metals are preferably calcium, magnesium, sodium or barium.
- a lubricating composition used according to the invention may comprise at least one dispersing agent, distinct from the succinimide-type compounds defined according to the invention.
- a lubricating composition suitable for the invention may also include at least one pour point depressant additive (also referred to as "PPD” agents for "For Point Depressant” in English).
- PPD pour point depressant additive
- pour point depressant additives By slowing the formation of paraffin crystals, pour point depressant additives generally improve the cold behavior of the composition.
- pour point lowering additives mention may be made of polymethacrylates alkyl, polyacrylates, polyarylamides, polyalkylphenols, polyalkylnaphthalenes, alkylated polystyrenes.
- a lubricating composition used according to the invention has a kinematic viscosity, measured at 100 ° C according to the ASTM D445 standard ranging from 4 to 50 mm 2 / s, in particular ranging from 5 to 40 mm 2 / s
- a lubricating composition used according to the invention has a kinematic viscosity, measured at 40 ° C according to the ASTM D445 standard ranging from 3 to 450 mm 2 / s, in particular from 10 to 400 mm 2 / s, preferably ranging from 15 to 70 mm 2 / s.
- a lubricating composition used according to the invention can be of a grade according to the SAEJ300 classification defined by formula (X) W (Y), in which X represents 0 or 5; and Y represents an integer ranging from 4 to 20, in particular ranging from 4 to 16 or from 4 to 12.
- additives chosen from friction modifiers, viscosity index modifiers, detergents, dispersants, anti-wear and / or extreme pressure additives , antioxidants, pour point depressants, defoamers and mixtures thereof; the contents being expressed relative to the total weight of said lubricating composition.
- the term "deaerating” is understood to mean the action making it possible to reduce the volume of air present in the volume of the lubricating composition. Deaeration is to be distinguished from antifoam which aims to reduce foam on the surface of the lubricating composition.
- the polyorganosiloxanes made it possible to significantly reduce the volume of air in the heart of the lubricating composition when said lubricating composition is in motion, for example when it is used to lubricate parts which may have high speeds. of rotation.
- the lubricating composition is used to lubricate a propulsion system of an electric or hybrid vehicle, in particular at the level of the reducer.
- the deaeration process is implemented with a lubricating composition intended to lubricate a propulsion system of an electric or hybrid vehicle, in particular of the bearings located between the rotor and the stator of an electric motor; and / or the transmission, in particular the reduction gear.
- Base oil Polyalphaolefin having a dynamic viscosity at 100 ° C of 40 mm 2 / s and at 40 ° C of 400 mm 2 / s;
- Fig. 1 shows the evolution of the air-in-oil dispersion over time, initially with the value at 0 min and up to 5 minutes.
- a torque meter (accuracy of ⁇ 0.002 N.m) placed on the motor shaft makes it possible to measure the drag torque and thanks to the speed of rotation, it is possible to obtain the power dissipated by the bubbling.
- the friction torques of the bearings are also subtracted from the torque measured by the sensor in order to obtain the only power dissipated by the splashing.
- the amount of air was determined at different temperatures according to the method described in Example 1. We have determined in this example only the "initial" air change.
