Definitions

  • the present invention relates to an oil composition for manual transmissions which is used to lubricate manual transmissions [manual transmissions of FR (Front engine, Rear drive) automobiles and manual transaxle of FF (Front engine, Front drive) automobiles] of automobiles which include passenger cars, trucks, large-sized cars such as buses, and tractors.
  • manual transmissions of FR (Front engine, Rear drive) automobiles and manual transaxle of FF (Front engine, Front drive) automobiles of automobiles which include passenger cars, trucks, large-sized cars such as buses, and tractors.
  • gear clashing As a feeling of ride on passenger cars and large-sized cars is investigated and improved, much attention has been paid to "gear clashing" and “sticking” which take place in shifting gear by a manual transmission, which troubles have not been considered so far.
  • the gear clashing generally occurs in a car which is running for a long distance, and in particular, it is often generated in the case that engine brakes are applied by shifting down abruptly at the time of a high-speed running, so as to reduce a speed of the car. If the gear clashing occurs in such a state, a gear change will not be performed smoothly, with the result that serious accidents will happen on occasion.
  • the sticking is also called “double gearing" and is a phenomenon which tends to occur in shifting gear at a low-speed running or at idling, and when the car is in the state of the sticking, the operation of a gear change is felt to be very heavy.
  • the friction between the synchronizer rings and the gear cones is naturally connected closely with a used lubricating oil.
  • the present inventors have extensively studied with the intention of solving these problems by using a new lubricating oil, and they have found that the occurrence of the sticking can be prevented by lowering a static coefficient of friction or a dynamic coefficient of friction under low-speed conditions and that the occurrence of the gear clashing can be inhibited by heightening a dynamic frinction coefficient under high-speed conditions.
  • an epochal lubricating oil has been developed which satisfies the above requirements and which has all properties such as an extreme pressure character and a stability against oxidation that the oil for manual transmissions should possess.
  • the present invention is directed to an oil composition for manual transmissions in which (A) 80 to 90 parts by weight of a base oil having a viscosity of 1 to 50 cSt at 100°C is blended with, as essential ingredients, (B) 0.2 to 5 parts by weight of a sulfurized oil or a sulfurized ester, (C) 0.1 to 5 parts by weight of phosphorous ester, (D) 0.2 to 5 parts by weight of zinc dithiophosphate, and (E) 2 to 5 parts by weight of a metallic detergent.
  • A 80 to 90 parts by weight of a base oil having a viscosity of 1 to 50 cSt at 100°C is blended with, as essential ingredients, (B) 0.2 to 5 parts by weight of a sulfurized oil or a sulfurized ester, (C) 0.1 to 5 parts by weight of phosphorous ester, (D) 0.2 to 5 parts by weight of zinc dithiophosphate, and (E) 2 to 5 parts by weight of a metallic detergent.
  • a base oil (A) is a lubricating oil fraction of a mineral oil series, a synthesized lubricating oil or a mixture thereof.
  • the synthesized lubricating oils include poly- ⁇ -olefins, olefin polymers, carboxylates of monovalent or polyvalent alcohols, polyethers, silicones, polyglycols, silicates, alkyl aromatic compounds, carbonates and hydrocarbon halides. Viscosities of these base oils at 100°C are within the range of 1 to 50 cSt, preferably 4 to 18 cSt.
  • Sulfurized oils and the sulfurized esters each of which is the essential ingredient (B) include sulfurized animal and vegetable oils as well as sulfurized fatty acid esters of synthesized oils.
  • An amount of an ingredient (B) to be blended is within the range of 0.2 to 5 parts by weight, preferably 1 to 3 parts by weight.
  • a phosphorous ester which is an essential ingredient (C) is a compound represented by the following general formula: (RO)aP(OH)b wherein a is a value of 1 to 3, preferably 2; b is a value of 0 to 2, preferably 1; and R is an alkyl group, an aryl group, an alkylaryl group having 3 to 25 carbon atoms, or a mixture thereof.
  • phosphorous esters examples include laurylhydrogen phosphite and oleylhydrogen phosphite.
  • An amount of the phosphorous ester to be blended is within the range of 0.1 to 5 parts by weight, preferably 0.5 to 2 parts by weight.
  • a zinc dithiophosphate which is an essential ingredient (D) is a compound represented by the following general formula: wherein R is an alkyl group, an aryl group, an alkylaryl group having 3 to 25 carbon atoms, or a mixture thereof.
  • zinc dithiophosphates examples include zinc diisopropyldithiophosphate, zinc di-2-ethylhexyldi­thiophosphate and zinc dinonylphenyldithiophosphate.
  • An amount of the zinc dithiophosphate to be blended is within the range of 0.2 to 5 parts by weight, preferably 0.5 to 3 parts by weight.
  • Metallic detergents each of which is an essential ingredient (E) include sulfonates, phenates, salicylates and phosphonates, and examples of the metals for them include Ca, Ba, Mg and Na.
  • An amount of the metallic detergent to be blended is within the range of 0.2 to 5 parts by weight, preferably 0.5 to 4 parts by weight.
  • a phenol series or an amine series anti­oxidant a rust preventive, a pour point depressant such as a polymethacrylate and a viscosity index improver which are all used usually in the lubricating oil.
  • a pour point depressant such as a polymethacrylate
  • a viscosity index improver which are all used usually in the lubricating oil.
  • compositions I to IV were prepared, in the following proportions, from ingredients which correspond to essential ingredients (A) to (E) in the order of top to bottom of each composition. Values in the following compositions represent amounts of the respective ingredients in terms of "part by weight”.
  • High-speed conditions (1) At an input revolutional speed of 4,000 rpm at a lever-pressing load of 4 kgf and at an oil temperature of 70°C, a gear change cycle of passing through neutral and four gear positions was repeaded 50,000 times, and the friction coefficient at this point of time was measured.
  • compositions I to IV of the present invention have the excellent properties that the dynamic frinction coefficients under the high-speed conditions (1) are high and the dynamic frinction coefficients under the low-speed conditions (2) are low, and it can thus be appreciated that the composi­tions of the present invention are desirable as the oils for manual transmissions.
