Abstract
A light weight road wheel having a relatively low mass moment of rotational inertia for use in a vehicle having an endless track. The wheel includes an inner metal member having a peripheral groove for receiving guide cleats of an endless track, and opposed peripheral rims having inner annular wall portions disposed against surfaces of said inner metal member. The rims are made of a fiber-reinforced composite material. Means are provided for securing the inner member and rim portions together. Elastomer tires secured to the outside surfaces of the rims, and segmented wear pads are located on inwardly facing surfaces of the peripheral groove.
Claims5
A light weight wheel having a low mass moment of rotational inertia, comprising
- inner, back-to-back metal discs adapted to be secured to a hub by a plurality of circumferentially spaced hub studs, said back-to-back discs forming a peripheral groove for receiving guide cleats of an endless track,
- opposed peripheral rims having inner annular wall portions located in said groove and disposed against inwardly facing surfaces of said metal discs to form a sandwich of said inner wall portions and metal discs,
- said rims being made of a fiber-reinforced composite material,
- means securing the metal discs and inner rim portions of the sandwich, and
- elastomer tires secured to the outer surfaces of said rims.
A light weight wheel having a low mass moment of rotational inertia, comprising
- two inner back-to-back metal discs adapted to be secured together by a plurality of wheel studs, said metal discs forming a peripheral groove for receiving guide cleats of an endless track,
- opposed peripheral rims having inner annular wall portions disposed against outer annular surfaces of said metal discs, said rims being made of a fiber-reinforced composite material,
- a plurality of fasteners extending through the inner wall portions of said rims and the metal discs to secure the rims and discs together, and
- elastomer tires secured to the outer surfaces of said rims.
A light weight wheel having a low mass moment of rotational inertia, said wheel comprising:
- aluminum members forming the center portion of said wheel, said members having a pair of wall portions extending therefrom in a radially outward direction to form a peripheral groove therebetween,
- opposed, peripheral, fiber-reinforced composite rims having radially extending inner annular wall portions disposed against surfaces of the outward wall portions of said aluminum members,
- a plurality of fasteners extending through said inner and outward wall portions securing said rims to the center portion of said wheel,
- a plurality of segmented wear pads disposed on opposed surfaces within said peripheral groove, and
- elastomer tires secured to outer surfaces of said rims.
