Abstract: A wheel assembly for a work machine, such as a mining dump truck, having a rotatable wheel having inboard and outboard rims mounted thereto. The outboard rim is mounted to a segmented rim-mounting flange which is secured to the inboard side of a flange projecting from the wheel.

The indentations may be elongated grooves, which are aligned with the axis of the wheel. The grooves are evenly spaced circumferentially about the wheel. Each groove's cross-section is an arc of a circle. The grooves extend into the rim more than one half of the rim's nominal thickness. The radius of the circle that form the cross-section is much larger than the groove's depth so that the edges of the grooves do not meet the rim's surface at a sharp angle. This intersection minimizes stress. The grooves may be in the rim's an inner or outer surfaces or in both surfaces. The application also discloses other configurations for the indentations.

Abstract: In a process for the forming of wheel rims in metal alloy, a cast blank undergoes a cold chip removal process by cutting its central area, its inner surface and its lateral surface in order to obtain a semi-finished work which is then heated and plastically deformed by flow forming along its lateral surface to obtain an inner edge, an outer edge and a middle portion with a defined machine allowance; the rim thus obtained undergoes another cold chip removal process by cutting in order to work it down to the required size; the latter process may be preceded by solution and age hardening heat treatments.

Abstract: Contained within a wheel hub housing is a variable ratio friction drive transmission. A chain drive input sprocket drives direction reversing spools arrayed around a central axis on shafts set at an angle to the central axis. A spool driven element rotates in the opposite direction. The spool driven element drives double cone elements on the shafts. A cone driven element then drives the wheel in the same direction as the input. The double cones are axially movable relative to the cone driving and driven elements. In a first axial position, for low torque, the driving element contacts a small diameter cone portion, and the driven element contacts a large diameter cone portion. As torque increases, the cones are moved by a cam mechanism so that the output ratio reverses and rapid input rotation produces high torque, slow output. A clutch and brake may be included.

Abstract: An improved system for attaching balance weights to a wheel utilizes a balancing flange which extends radially inwardly from a wheel rim for mounting the balance weights. The system is particularly suited for use with full face wheels of the type wherein a full face cast or forged disk is joined to a partial wheel rim. The balancing flange may be suitably formed on the outboard portion of the partial wheel rim, and then butted against and welded to an axially extending annular flange formed on the inboard surface of the wheel disk. Balance weights may then be clipped to the flange at specified locations to balance the wheel and a tire mounted thereon. As the balance weights will not be visible from the outboard surface of the wheel, the cosmetic appearance of the wheel is not impaired. Preferably, the balancing flange is positioned in or near the plane of rotation of the center of mass of the wheel and tire assembly such that the balance weights do not create a force couple acting on the wheel.

Abstract: Vehicle wheel nut inserts adapted to extend into the stud-receiving openings of a vehicle wheel and particularly, a non-ferrous vehicle wheel and lug nut assemblies thereof. The inserts are uniquely designed so that the inserts can be permanently locked in the stud-receiving openings of the vehicle wheel.

In this way, a spring-type loading is imposed on the lug nut preventing an unauthorized vibrational unwinding of the lug nut. The insert will deflect when tightened against the wheel opening by a lug nut to thereby provide a Belleville spring effect.
