    Abstract: A wheel-speed sensor utilizing a magnetic pickup and adapted for use on an automotive vehicle. A cup-shaped drive wheel has an elastomeric friction ring secured to the inside surface of the rim of the cup. The friction ring drives a driven wheel and tone wheel element of an assembly including a pickup whose components are assembled on a unitary plastic molding which also serves as the bobbin for the coil. The mounting element of the driven wheel and pickup is a unitary stamping attached to a nonrotatable portion of the vehicle.

    Abstract: The tone wheel is a heavy walled steel stamping having a flanged central opening adapted for pressing on to a pilot turned on the outside surface of the wheel hub, and a cylindrical flange contiguous to the usual offset portion of the brake disc and having teeth formed on its inside surface. The spaces between the teeth are filled with adhesive nonmagnetic material so that the tooth tips and the nonmagnetic material provide a smooth unbroken cylindrical surface. A radial adjustment for establishing a predetermined clearance between a pickup and the tone wheel is provided by a generally rectangular projection on the back of the pickup which fits into an elongated slot in the pickup bracket. The output of the pickup is used to control the adaptive braking system.

    Abstract: A control valve for use in an adaptive braking system to modulate the pressure delivered to a braked wheel when a skid condition is sensed. The adaptive braking control valve will permit normal unobstructed flow of pressure from the driver''s control valve to and from the wheel brake actuating device. Upon sensing an imminent skid condition by the adaptive braking system, a solenoid will be energized that allows a source of pressurized fluid to enter the control valve. The source of pressurized fluid in the control valve will move a diaphragm which closes the pressure received from the driver''s control valve and, subsequently, reduces the pressure in the wheel brake actuating device. When an imminent skid condition no longer exists, the solenoid will de-energize thereby terminating the source of pressurized fluid from the control valve. The pressurized fluid acting against the diaphragm is decayed by a bleed orifice, thereby restoring normal communication between the driver''s control valve and the wheel-brake actuating device. A small bypass is included to allow a slow pressure build rate in the wheel brake actuating device during the time interval between the stopping of normal communication and the reduction of pressure from the wheel brake actuating device.

    Abstract: A hydraulic device is disclosed which includes a diaphragm which assures separation between two incompatible fluids communicated into a housing so that a fluid leaking past its corresponding seal cannot damage the seal which prevents leakage of the other fluid. The hydraulic device includes a piston slidably mounted within a housing, and the aforementioned diaphragm interconnects the piston with the housing wall. The peripheral edge of the diaphragm is received in a passage which communicates the interior of the housing device with the exterior. The diaphragm is provided with a pair of resilient lips which extend into the aforementioned passage and are adapted to control fluid communication therethrough. The lips are responsive to movement of the piston to seal against the passage during stroke of the piston in one direction due to the partial vacuum created within the housing, to thereby prevent entry of exterior contaminants into the housing. Upon stroke of the piston in the opposite direction, the increase of fluid pressure in the housing expels the accumulated fluid seepage within the housing past the lips to the housing exterior.

    Abstract: A compact driven wheel, tone wheel and pickup assembly mounted on a unitary housing. The assembly has a leaf spring section which urges the driven wheel into contact with an elastomeric portion of a drive wheel mounted on the vehicle axle or wheel hub. The pickup generates an electric signal which is representative of the rotational speed of the vehicle wheel. The drive wheel can be mounted without removing the axle shaft from the axle housing.
