Reduced friction wet disc brake

A wet disc brake comprising:

• a stator;
• a rotor, said rotor and said stator together defining a fluid chamber;
• a viscous first fluid received within said fluid chamber;
• and
• said rotor having a plurality of discs rotating within said chamber, each said rotor disc being comprised of at least two parts, with a first part rotating with said rotor, and a second part selectively rotating with said rotor, said rotor being provided with a supply of a second fluid to create a fluid bearing between said first and second parts, and said fluid bearing stopping rotation of said second part with said first part, a control controlling said supply of fluid to stop the supply of fluid to said fluid bearing when it is desired to slow rotation of said rotor, said stator surrounding said rotor, said second part being biased into contact with said first part, and said bias being overcome by said fluid bearing, and said rotor including a central shaft with said rotor discs being positioned outwardly of said central shaft, and a fluid supply path extending along an axis of said shaft, said supply jets extending radially outwardly from said supply path to an outer peripheral surface of said rotor, and between said first and second parts of said rotor discs, and there being a plurality of said jets for each of said fluid bearings.

A wet disc brake comprising:

• a stator;
• a rotor, said rotor and said stator together defining a fluid chamber;
• a viscous fluid received within said fluid chamber;
• pistons for selectively bringing a braking disc into contact with said rotor to slow rotation of said rotor;
• and
• said rotor having at least one disc rotating within said chamber, said rotor disc being comprised of at least two parts, with a first part rotating with said rotor, and a second part selectively rotating with said rotor, said rotor being provided with a supply of a fluid to create a fluid bearing between said first and second parts, and said fluid bearing stopping rotation of said second part with said first part.
