Abstract

Traction fluids comprising Formula I, II, III, IV, V, VI, VII or a mixture thereof in combination with a base stock, a viscosity modifier, an anti-foaming agent, and an additive package.

Claims (25)

1. A traction fluid comprising at least one compound of:

or

a combination thereof.

2. The traction fluid of claim 1 , wherein Formula III, IV, V, VII or a mixture thereof are present in amount between about 0.1 wt % and about 50 wt % of a final formulation of a traction fluid.

3. The traction fluid of claim 1 further comprising a traction fluid base stock in an amount between about 30 wt % and about 99.78 wt % of the final formulation.

4. The traction fluid of claim 1 further comprising a traction fluid base stock in an amount between about 45.4 wt % and about 92.2 wt % of the final formulation.

5. The traction fluid of claim 1 further comprising an anti-foaming agent.

6. The traction fluid of claim 1 further comprising an anti-foaming agent in an amount between about 0.01 wt % and about 0.5 wt % of the final formulation.

7. The traction fluid of claim 1 further comprising an anti-foaming agent in an amount of about 0.1 wt %.

8. The traction fluid of claim 1 further comprising a viscosity modifier.

9. The traction fluid of claim 1 further comprising a viscosity modifier in an amount between about 0.01 wt % and about 10 wt %.

10. The traction fluid of claim 1 further comprising a viscosity modifier in an amount between about 2 wt % and about 3.4 wt % of the final formulation.

11. The traction fluid of claim 1 , further comprising at least one additive selected from the group consisting of: antioxidant agents, antiwear agents, extreme pressure agents, detergents, dispersants, antifoamer, anti-rust agents, friction modifiers, corrosion inhibitors, pour point depressants, and a combination thereof, wherein the combination thereof constitutes an additive package.

12. The traction fluid of claim 11 , wherein the additive package is present in an amount between about 0.01 wt % and about 10 wt % of the final formulation.

13. The traction fluid of claim 11 , wherein the additive package in an amount of about 5.7 wt %.

14. The traction fluid of claim 1 , further comprising a base stock, viscosity modifier, an anti-foaming agent and an additive package.

15. A traction fluid comprising:

a compound of Formula III, IV, V, VII or a mixture thereof of claim 2 in an amount between about 0.1 wt % and about 50 wt %;

base stock in an amount between about 30 wt % and about 99.78 wt %;

a viscosity modifier in an amount between about 0.01 wt % and about 10 wt %;

an anti-foaming agent in an amount between about 0.1 wt % and about 0.5 wt %; and

additive package in an amount between about 0.01 wt % and about 10 wt %.

16. The traction fluid of claim 1 having a Brookfield viscosity (cP) @−30° C. of between about 1730 and 21500.

17. The traction fluid of claim 1 having a traction coefficient of between about 0.0867 and about 0.0933.

18. The traction fluid of claim 1 having a kinematic viscosity (cSt) @40° C. of between about 10.24 and 24.62.
