Abstract:
A laminate wheel protector (10, 30, 40, 50, 60, 80, 90, 180) includes layers of canvas cloth impregnated with synthetic resin that is polymerized through heat and pressure for insulating a hub or drum of a machine from a wheel. A method for creating a laminate wheel protector (10, 30, 40, 50, 60, 80, 90, 180) includes applying pressure to layers of canvas saturated in synthetic resin, applying heat to polymerize to create a laminate, cutting the laminate to form an outer circular circumference, an inner circular opening and a plurality of bolt holes. The laminate wheel protector (10, 30, 40, 50, 60, 80, 90, 180) has numerous advantages including preventing oxidation, rust, and galvanic electrolysis between metallic surfaces, reduce heat transfer and vibration, increase longevity and provide proper contact between metallic surfaces among numerous other advantages.
Abstract:
A tapered correction plate (20, 60, 70, 80) and method of using the correction plate (20, 60, 70, 80) for lateral runout of a disc brake rotor (30) is described. The tapered correction plate (20, 60, 70, 80) is installed between the hub (14) and brake rotor (30) of an automobile such that the thinnest portion of the correction plate is aligned with the angular position on the hub (14) and rotor (30) corresponding to the maximum lateral runout. The mounting geometry of the correction plate (20, 60, 70, 80) may include any one of a number of configurations including circular openings (26), slotted openings (66, 86) having a smooth or gear-like perimeter, or an outer perimeter defining a gear like shape or open ended half slots (76). Each type of mounting geometry is suitable for mating with existing lug patterns while enabling adjustment of an angular orientation of the correction plate (20, 60, 70, 80) with respect to the hub and rotor. The correction plate may also consist of one washer or a number of washers (94, 96) of appropriately varying thicknesses that are arranged to correct runout.
Abstract:
The claimed wheel adapter made of light metal, with mounting aid, for bolts (20) that are set in bores such as blind holes (2) and that lack a circular segment in the head surface has a blind hole diameter that is larger than the blind hole diameter of wheel adapters made, for exemple, of steel. Between the head of the wheel fixing bolt (20) and the blind hole base (6) there is a disk (10) made of compression-proof material, the diameter of which is adapted to the enlarged diameter of the relevant blind holes of the wheel adapter so as to establish a larger contact surface. The disk is also fitted with a retention device (14; 18; 32) to prevent turning.
Abstract:
The proposal is for a system for centrally securing a wheel (1) with a central drilling (2) to an adapter flange (12) of an axle of a vehicle, in which, according to the invention, a double taper ring (23) can be clamped between the wheel (1) and a central section (17) of the adapter flange (12) by means of a lock screw (5) or lock nut (26) to provide a friction bond between the wheel (1) and the flange (12).
Abstract:
Un moyeu (ME) est destiné à équiper un essieu de véhicule et à être solidarisé par vissage à une roue (R) comportant un voile (VR) muni d'au moins deux premières zones (Z1 ) sensiblement planes et comportant chacune un premier trou (T1) propre à être traversé par une tige (TV) d'une vis (VS). Ce moyeu (ME) comprend un disque d'interface (Dl) muni d'au moins deux secondes zones (Z2) planes et comportant chacune sur une face arrière (FR), opposée au voile (VR), un logement (LE) dans lequel est défini un second trou (T2) et est immobilisée une partie périphérique (PP) d'un écrou (EV) présentant une forme concave par rapport à cette face arrière (FR) et propre à définir une réserve élastique pour le serrage d'une vis (VS) participant au vissage de la roue (R).
Abstract:
A safety device (10) comprises a plurality of wheel nut position indicators (30) captively but rotatably mounted in a holder (12). The position indicators are attachable to respective wheel nuts (40) by means of fastener covers (50). When attached, the fastener covers (50) act to secure the device to a wheel and to transfer any rotational movement, i.e. loosening, of a wheel nut (40) to an associated position indicator (30). The indicators (30) each have an indicator portion, e.g. a triangular pointer (34) and are so arranged that this portion emerges from the holder and hence becomes visible when any such rotation occurs. By removing a fastener cover (50) an indicator (30) is disengaged from a wheel nut (40) and the individual wheel nut can be tightened without having to remove the entire device (10). The invention helps reduce errors in wheel nut maintenance and inspection and allows simultaneous application of a plurality of indicators in one operation.
Abstract:
A magnesium alloy wheel having a waterproof structure where a seal ring is provided on a member which is connected to a center hole (50) including a hub hole (17). The wheel comprises a liner (53) by which contact corrosion of the different metals is avoided is provided between a hub flange (2) and the face (18) of a wheel (1) at which the wheel (1) is attached to a vehicle shaft (3) and between a hub (4) and the face (18), and a flanged washer (44) which has a recess in cross section and whose surface has a property of a small contact potential difference with respect to magnesium and is disposed at a position where a fastening member (43) for fastening the wheel (1) to a rim (42) is pressed against a disc (7). The contact corrosion caused by the stay of conductive medium such as water or salt water is prevented and the durability is significantly improved.
Abstract:
The light alloy wheel assembly for motor vehicles comprises a rim (2) including: a channel (4) designed to house a tire (G), a central flange (5) for fixing the rim (2) to a motor vehicle hub (M), a connection structure (6) with disc or spokes between the flange (5) and the channel (4), a false hub (3) designed to be fixed on the hub (M) and to allow fixing thereon of the flange (5), first means (10, 11, 12) of tightening and centering the false hub (3) on the hub (M), and second means of tightening and centering of the flange (5) on the false hub (3). The second tightening and centering means comprise: a plurality of centering pins (21) on the false hub (3), a corresponding plurality of bores (22) on the flange (5), a central threaded pin (23) formed on the false hub (3), a corresponding central bore (24) formed in the flange (5), a nut (25) designed to be screwed on the threaded pin (23), and a striker seat (26) for the nut (25) formed on the flange (5) around the central bore (24). Such a wheel assembly permits mounting of a single-nut wheel on the hub of any motor vehicle.
Abstract:
A self-locking nut assembly (10) capable of resisiting inadvertent loosening due to vibration or cyclic loading. The assembly (10) comprises a head portion (12) adapted to receive as panner or wrench for tightening or loosening the assembly on a bolt or stud, and an internal threaded portion (14) provided in connection with the head portion (12). The assembly (10) further comprises a locking member (18) in the form of a locking washer comprising two halves (26) of semi-circular shape. The locking member (18) has an outer peripheral surface (22) that is inclined with respect to an axis of rotation (16) of the head portion (12), and also has an inner surface (24). A thrust member (32) bears against the locking washer (18), and has an inner peripheral surface (34) designed to engage with the outer peripheral surface (22) of the locking washer (18). When an axial compressive load is applied to the locking member (18), for example, by tightening the assembly on a threaded fastener, the respective peripheral surfaces engage to create a wedging effect, wherein the inner surface (24) of the locking member (18) is forced against the thread of the fastener on which the assembly is being tightened, so as to grip the thread and inhibit loosening due to vibration.
Abstract:
A vehicle wheel attachment offers an increased tread to support the vehicle on soft ground. A drum-like body (6) is held against the wheel (1, 2) by a co-axial anchorage device (4, 5, 8, 9) secured to the wheel using the existing wheel studs. The normal nuts are permanently replaced by special ones (10, 19, 22) which provide slots (13), screw threads (17, 20, 23) or other means by which an anchorage member (4) can be easily secured and removed without disturbing those nuts. A rod (5) from the anchorage member to the outer end of the drum, to receive the clamping means (9), is mounted, or has the ability, to flex within a limited cone. The drum (6) may have a ribbed tread (40) and provision can be made for further pieces to fit the valleys (41) and thereby alter the tread.
