Brake cooling fluid diverter for an off-highway machine
First Claim
1. A method of cooling a first friction brake system and a second friction brake system in a machine having a brake cooling system including fluid and a fluid diverter, the method comprising:
- determining whether the first friction brake system is activated;
determining whether the second friction brake system is activated;
circulating, with a first set of pumps including at least one pump, fluid through the brake cooling system to the first friction brake system and the second friction brake system;
circulating, with a second set of pumps including at least one pump, fluid through at least one hydraulic system;
combining the flow of fluid from the first set of pumps and the flow of fluid from the second set of pumps; and
diverting fluid between the first friction brake system and the second friction brake system based on a first brake enable switch for the activation of the first friction brake system and based on a second brake enable switch for the activation of the second friction brake system.

Abstract
The disclosure relates, in one aspect, to a friction brake cooling system for a machine. The cooling system includes at least one pump connected to at least one reservoir containing cooling fluid. A controller is configured to divert a cooling fluid flow through a valve to a first friction brake system and to a second friction brake system based on the use of the systems. In another aspect, the disclosure relates to a method of cooling a first friction brake system and a second friction brake system including diverting a flow of brake cooling fluid to the systems based on the use of the systems.

7. A friction brake cooling system comprising:
-
at least one first pump in a first set of pumps connected to at least one reservoir containing fluid and configured to provide a fluid flow to at least one valve in fluid communication with the first pump; at least one second pump in a second set of pumps connected to the reservoir and configured to provide fluid to at least one hydraulic system and configured to provide fluid flow to the valve in fluid communication with the first pump and the second pump; a first friction brake system in fluid communication with the valve and a second friction brake system in fluid communication with the valve such that cooling fluid from the reservoir is pumped through the valve to the first friction brake system and to the second friction brake system; at least one controller configured to divert the cooling fluid flow through the valve to the first friction brake system and to the second friction brake system based, on a first brake enable switch for the activation of the first friction brake system and a second brake enable switch for the activation of the second friction brake system. - View Dependent Claims (8, 9, 10, 11, 12)
