Abstract: An integral tire and rim assembly includes a flanged annulus having an uninterrupted, substantially constant diameter outer surface, a centrally disposed spider and a tire having inextensible beads of a diameter smaller than the diameter of the rim flanges. A method for fabricating the integral tire and rim comprises the steps of forming an annulus having a substantially uniform diameter and a first generally radially extending flange, forming a spider, securing the spider within the flange, mounting a tire on the rim and forming a second generally radially extending flange in the annulus, thereby securing the tire on the rim between the two flanges.

Abstract: The present invention relates to a solenoid having a pole and armature construction wherein, when a predetermined constant current is applied to the solenoid winding, the magnetic force attracting the armature toward the pole decreases as the armature is moved in one direction relative to the pole and, the distance the armature is moved is substantially proportional to the current applied to the winding. These operating characteristics are achieved by a solenoid having a field member provided with a pole portion on one end thereof, and having an armature connected to the opposite end for movement relative to the pole portion. The armature is provided with an edge portion which is spaced from the pole portion to define an air gap therebetween. The pole portion produces a magnetic field which exerts a magnetic force on the armature edge portion in one direction relative to the pole portion.

Abstract: A mold for making steering wheels by winding resin impregnated fibers. The mold includes a hub support pedestal to support a hub about which fibers are wound, means having a rim forming recess, a plurality of ramps connecting said means having said rim forming recess to said pedestal and means for pressing said fibers against said ramps.

Abstract: The present invention relates to a position sensor which can be utilized as a height sensor in an automatic vehicle suspension system. The sensor comprises a telescoping assembly including an elongate shaft having one end which is axially slidable within an outer housing. The telescoping assembly is connected between sprung and unsprung vehicle frame members. The outer ends of the shaft and the housing are each provided with a unique bifurcated socket unit and an associated retaining clip for attachment to a ball element connection point on the associated vehicle frame member. A pair of magnets are carried by the shaft and are adapted to generate a first magnetic field having one polarity and extending axially along a first portion of the shaft and a second magnetic field having an opposite polarity and extending axially along a second portion of the shaft.

Abstract: A mechanical parking brake mechanism having a self adjusting feature to compensate for friction pad wear suitable for use with a hydraulic disc brake is disclosed. The embodiment disclosed teaches a parking brake mechanism separate and independent of the hydraulic brake actuating mechanism. Thus the parking brake mechanism may be combined with any disc brake as an add-on device for use on motor vehicles.

Abstract: A pin type floating caliper low drag disc brake for a vehicle is disclosed in which the braking torque is transferred directly to a vehicle frame member for a non-steerable wheel and directly to a wheel spindle for a steerable wheel. An outboard brake pad assembly is mounted on the caliper which floats on a first pin located adjacent the leading edge of the caliper and an inboard brake pad assembly floats on a second pin located adjacent the trailing edge of the caliper. The braking torque is transferred through the pins to the vehicle.

Abstract: A method for making a wheel and a wheel so made is disclosed in which the tire bead seats in the rim are deformed inwardly, the wheel is held by the deformed bead seats, and the bolting surfaces of the web are machined in fixed relation to the bead seats. Preferably, the bead seats are deformed sequentially to work welded metal attachment of a web to the rim, and then place it under compression. Preferably, the bolting surface is machined in the form of a flat cone that is approximately three degrees from planar, and the lug holes are chamfered to place surrounding metal in direct compression, and to deform the conically shaped bolting surfaces into flat engagement with planar surfaces on the hubs on which the wheels are to be installed. A method of determined angularity of the web to the rim is utilized to reject poorly aligned webs before machining the bolting surfaces, and thereby prevent undo thinning of the web, and as a means of product control.

Abstract: An edge for frontal engagement with air flow as occurs when vehicles are moving in an air environment. The edge is elongate and intended to wrap around an existing corner where two substantially planar surfaces intersect, one of the planar surfaces being a front surface and the other planar surface being a rearwardly receding flanking surface such as a top surface or a side surface of a vehicle. The edge rises abruptly from the front plane and moves forwardly and outwardly in a convex arc to a point of abrupt inflection outside of the flanking plane and adjacent the front plane as extended through the flanking plane. The discontinuity or inflection is a change from convexity to concavity formed by alternate concavity and convexity and progressing generally toward faired contact with the flank plane.

Abstract: A disc brake having an improved automatic adjustment mechanism is disclosed. The preferred brake includes a rotary actuating assembly for axially translating a push rod which abuttingly urges a pair of friction element assemblies into engagement with a rotatable disc. A nonrotatable element of the actuating assembly threadably engages the push rod, such that when the push rod is rotated, it is axially advanced to decrease the friction element clearance. A clutch mechanism circumscribes the push rod and communicates, by way of a lost motion connection, with a rotatable element of the actuating assembly to effect rotation of the push rod after a predetermined rotation of the rotatable element. Thus, clearance adjustments are made in response to predetermined wear of the friction elements, thereby maintaining brake clearance within predetermined limits.

Abstract: A hydraulic braking system is provided for vehicles which frequently experience variable loading conditions ranging from maximum to near minimum gross vehicle weights. The system comprises dual proportioning valves, hydraulically in series with one another, one valve includes a unique spring driven digital cam which, in response to compression of the vehicle suspension system, selects the desired master cylinder to brake pressure relationship for the vehicle load condition.

Abstract: A floating caliper disc brake of the rail-slider type is disclosed. A low friction member is positioned between the anchor plate rails, upon which the caliper is supported, and the opposing caliper rails. The low friction member permits free movement of the caliper with respect to the anchor plate and further functions as an anti-rattle device.
