Abstract
A device for monitoring a difference between the speeds of rotation of two rotating members featuring a differential gear assembly having two driven gears and at least one follower gear intermeshed and disposed within a rotatable housing is disclosed. The follower gear is rotatably connected to the housing to permit the housing to rotate at a speed proportional to a difference in speed between the two driven gears, the driven gears being connectable, respectively, to two different rotating members whose speeds are to be compared. A rotary fluid valve is disclosed which responds to the rotation of the rotatable housing to generate fluid output signals indicative of a difference in speed between the two rotating members. A system for automatically controlling the application of brakes to a wheeled vehicle traveling in either a forward or reverse direction which employs the monitoring device and the fluid valve to generate a fluid signal to correct a wheel skid or spin condition is also disclosed.
