Abstract:

An efficient lubrication system for wet plate brake assemblies includes a flow control system that passes lubricant for cooling and lubrication through interdigitated wet brake plates when the plates are engaged. When the plates are disengaged, the wet plate assembly is controlled to limit its displacement by means of a pin and spring such that a gap is provided around the brake plates to provide a preferential path for lubricant, thus minimizing parasitic losses.
