Abstract:

A direct drive windshield wiper assembly including at least one brushless DC motor providing a drive torque through an output that is rotatable about the longitudinal axis of the motor and a windshield wiper that is driven by the motor about the longitudinal axis in a repeated wiping motion across the surface of a windshield. The motor including a planetary gear set having an output shaft, the gear set being coaxially disposed relative to the rotational output and the longitudinal axis of the motor and operatively interconnecting the drive torque and the windshield wiper, the gear set further operable to reduce the speed of the rotational output of the motor to the windshield wiper through the output shaft of the gear set.

Abstract:

A windshield wiper assembly including at least one motor having an output shaft and a windshield wiper operatively connected to the output shaft. The motor includes a stator adapted to provide an electromagnetic flux and a rotor assembly supported for rotation about the stator. The rotor assembly includes a back iron and an annular magnet mounted to the back iron so as to be disposed in radially spaced relationship about the stator. The rotor assembly is operatively connected to the output shaft and responsive to electromagnetic flux generated by the stator so as to provide a rotational force to the output shaft to drive the windshield wiper in repeated wiping motion across the windshield.

Abstract:

A tandem windshield wiper system including a first windshield wiper assembly having a first lever arm that is adapted to operatively move in a repeated wiping motion across the surface of a windshield. A second windshield wiper assembly having a second lever arm is spaced apart from the first windshield wiper assembly and is rotatable about a second wiper longitudinal axis and adapted to operative move in a repeated wiping motion across the surface of the windshield. A brushless DC motor that includes a planetary gear set having an output shaft is disposed between the first and the second wiper assemblies. The gear set is operable to reduce the speed of the rotational output of the motor through the output shaft of said gear set. A bellcrank having a central attachment point and a first and a second end is also included. The central attachment point is fixedly mounted to the output shaft of the motor.

Abstract:

A windshield wiper assembly including at least one motor having an output shaft and a windshield wiper operatively connected to the output shaft. The motor includes a stator adapted to provide an electromagnetic flux and a rotor assembly supported for rotation about the stator. The rotor assembly includes a back iron that defines an inner circumference and a plurality of magnets disposed in spaced parallel relationship relative to one another about the inner circumference of the back iron and in radially spaced relationship about the stator. The rotor assembly is operatively connected to the output shaft and responsive to electromagnetic flux generated by the stator so as to provide a rotational force to the output shaft to drive the windshield wiper in repeated wiping motion across the windshield.

US Classification:

310268

Abstract:

Four embodiments of a reluctance type rotational speed sensor are disclosed. In the first embodiment, an annular magnet circumscribes a sensing coil having a unitary rotor nested within it, and is disposed between two elements which comprise the stator. In a second embodiment, a magnet is disposed between two halves which comprise a rotor, the entire assembly nesting within a sensing coil and being disposed between the two stator elements. In the third embodiment, the rotor carries multiple magnets in an axially opposed position with respect to teeth formed on the stator. The magnetic flux in the magnetic circuit increases and decreases as the rotor magnets alternate between aligned and non-aligned positions enabling measurement of angular speed in accordance with the increase and decrease of magnetic flux. Any of the first three embodiments may be used, with minor modifications, in environments where a rotating shaft turns within a stationary bore, or where a rotting bore turns about a stationary shaft. The fourth embodiment incorporates the features of the first three and further includes a caliper-like stator and coil assembly which may be removed for service without requiring extensive disassembly.

Inventors:

Assignee:

Rockwell International Corporation - Pittsburgh PA

International Classification:

B23K 3102

US Classification:

228182

Abstract:

A modified fast fade rear axle housing of rectangular cross-section having a shortened neck shape to maximize the torsional strength of the housing in the expanded annular section where the transition zone joins the center differential receiving portion and the beam arms of the axle. Two U sections are welded after being bent to provide parallel legs joined to a web by arcuate corner sections. The axially extending curvature of the corner sections and the web are respectively convexly defined by a first radius R. sub. 1 measured from a true origin at the vertical axis of the differential receiving portion where it intersects the longitudinal axis of the axle and a second eccentric radius R. sub. 2 measured from a displaced origin and concavely by blending radii R. sub. 4 and R. sub. 3 which are substantially less than corresponding blending radii in drive axle housings in which the convex curvature is concentric with the true origin.
