    摘要: A fluid operated system for controlling a brake applicable to a vehicle wheel having a flywheel, driven by an unpowered vehicle wheel, connected to the vehicle brake pedal and adapted to disconnect the flywheel from the unpowered wheel to rotate independent thereof when the brake pedal is operated. Upon vehicle deceleration, the flywheel slides forward in the direction of vehicle movement due to inertia and slidably presses against a brake pad which decelerates the flywheel at a rate proportional to vehicle deceleration. A fluid operated valve having a housing containing spaced fluid inlet, storage and outlet chambers which open onto a concave base of the housing is employed to sense the rotational speed of the flywheel. A collar, connected to the flywheel so as to rotate in unison therewith, slidably engages the concave base and contains a slot which alternately connects the inlet and storage chambers and thereafter, the storage and outlet chambers together to generate a fluid output signal in the outlet chamber which is a function of the rotational speed of the flywheel. A wheel speed senser is used to sense the rotational speed of a vehicle wheel to which the brake is applied. A fluid valve, connected to the flywheel speed senser and the wheel speed sensor, generates a brake controlling response in accordance with a difference between the speeds of the wheel and vehicle and is operatively connected to the brake to limit the difference. Additional features include a manual override assembly which insures normal brake operation upon failure of the fluid operated system, and a pendulum arrangement associated with the flywheel to eliminate errors in vehicle speed sensing caused by gravity when the vehicle travels on steep inclines.

    摘要: 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.

    摘要: A spring loaded fluid operated valve for use in sensing the speed or rotation of a rotating member, shaft or collar is disclosed. The valve features fluid inlet, outlet and storage chambers, each of which have openings spaced from and selectively aligned relative to one another. A rotating body whose speed of rotation is to be sensed, slidably engages the chamber openings in a fluid tight manner and defines a slot or recess therein which communicates with each of the openings in a repetitive and sequential manner to alternately transfer a portion of the fluid introduced into the inlet chamber to the storage chamber and, thereafter, from the storage chamber to the outlet chamber. In the particular embodiment of the valve disclosed herein, the openings are disposed on a concave base of a housing containing the chambers so as to conform to the circular periphery of the rotating shaft or collar defining the slot. The slot rotates across each of the openings during each revolution of the shaft or collar.
