International Classification:

H02K 2138

US Classification:

310155

Abstract:

A speed sensor for a vehicle wheel has a rotating tone wheel and a stationary E-shaped magnetic sensor having a sensing pole of square loop magnetic material positioned between two switching poles. A coil is wound on the sensing pole and the poles are magnetized to periodically reverse the flux in the sensing pole as the teeth on the tone wheel alternately pass the switching poles to induce a signal voltage in the coil corresponding to wheel speed and substantially free of noise components due to misalignment and vibrations of the tone wheel upon relative rotation of the tone wheel and magnetic sensor.

International Classification:

G01P 1500

US Classification:

73505

Abstract:

A rate sensor is disclosd for use in applications requiring high reliability such as in aircraft or tank gun stabilization systems. The rate sensor consists of a sensor rotor supported within a volume of magnetic fluid contained in a sensor housing to which is applied a magnetic field, levitating the sensor rotor in a central location within the housing cavity. A plurality of sensor means are provided positioned about the axis of the sensor rotor detecting the relative movement between the sensor rotor and the sensor housing occurring upon rotation of the housing from which an output signal corresponding to the rate of change of rotation of the housing. The magnetic field is produced either by a series of permanent magnets arranged about the housing, by the sensor mass formed with permanently magnetized portions, or by a series of electromagnets which may also function in a closed-loop stabiization system to more accurately maintain the central position of the sensor mass in the housing and provide a variable damping of the rotor.

International Classification:

US Classification:

310168

Abstract:

A speed sensor for a vehicle wheel has a rotating tone wheel with a stationary magnetic sensor having a pair of sensing poles positioned proximate the tone wheel teeth. Coil means are wound on the poles and the poles are magnetized to induce a signal voltage in the coil means corresponding to wheel speed. The poles are phased relative to the teeth on the tone wheel to reduce noise voltage components in the wheel speed signal voltage due to axial misalignment and vibration of the tone wheel. The poles may be phased 180. degree. relative to one another with respect to the teeth on the tone wheel so that one pole is in registry with a tooth when the other pole is in registry with a space between two teeth. With this arrangement the combined reluctance of the poles is approximately constant.

Assignee:

The Bendix Corporation - Southfield MI

International Classification:

F15B 910
F15B 1517

US Classification:

91378

Abstract:

A rack and pinion power steering system includes a housing within which a rotatable pinion engages a rack to impart movement thereto. The rack is substantially U-shaped having a pair of arms with coaxial openings to slidably receive a rod. The rod extends from the housing to operatively engage a pair of dirigible wheels and the rod is movable relative to the housing when the rack is moved to change the direction of the pair of dirigible wheels. A sleeve on the rod is disposed between the pair of arms and is provided with a valve member to communicate pressurized fluid from a pressure source to a pressure chamber to assist the movement of the rod.

US Classification:

418 61R

Abstract:

An actuator for rotating an output member, having an epicyclic transmission adapted to rotate the output member in response to the motion of a rotor which contains a plurality of radial projections which interact with a stator or non-rotating portion of the actuator to produce a rotating tangential force vector directed substantially perpendicular to the radial projections.

Assignee:

The Bendix Corporation - Southfield MI

International Classification:

H02K 710

US Classification:

310 82

Abstract:

An electric motor or actuator having a housing and a stator mounted to the housing about a central axis. The actuator includes a rotor that is mounted within the housing in surrounding relationship to the stator for moving in an orbiting manner with respect to the stator poles in response to the magnetic force. The rotor has an axis that is eccentrically positioned from the central axis by a distance e. sub. 1 and further includes a double eccentric that is mounted in rotating, surrounding relationship to the rotor and drivingly coupled thereto for transmitting the motion of the rotor to a ring gear. A stationary gear is attached to the housing and is mounted in surrounding relationship to the ring gear. The stationary gear includes a set of gear teeth which react with a coacting set of gear teeth on the ring gear, thus causing the ring gear to turn in response thereto. The rotating motion of the ring gear is transmitted to an output gear which is mounted in surrounding relationship to the stator gear and to the ring gear.

International Classification:

B62D 510

US Classification:

180148

Abstract:

A rack and pinion power steering device includes a housing which defines a cavity and the housing communicates with a pressure source. A pinion extends into the housing cavity to engage a rack which is movably supported by a sleeve member. The rack engages a valve member to control communication from the pressure source to a pair of chambers within the sleeve member. The pair of chambers are separated by a partition and a pair of rods are fixedly secured to the partition. Extending from the housing the pair of rods cooperate with dirigible wheels to control the direction of the dirigible wheels. The housing includes portions which slidably support the sleeve member and the pair of rods and partially define the pair of chambers. The sleeve member and pair of rods are movable relative to the housing in response to pressure within the pair of chambers.
