Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
208 words
A disc brake assembly comprising: a fixed caliper; an annular axially slidable disc having a central aperture and mounting bolt-receiving apertures; an axle support member having said caliper secured thereto and taking braking torque reaction when the brake is actuated; a live axle rotatably supported in said axle support member and extending axially outward therefrom and having means thereon mounting a wheel to be braked and said disc in axially slidable and rotatably driven relation, said mounting means including a flange on said axle, an axle extension section providing a pilot for the wheel, an annular plate in axially spaced relation to said flange and drivingly secured to said axle extension section for rotation therewith, mounting bolts extending through aligned mounting boltreceiving apertures in said flange and disc and plate and wheel and spaced circumferentially about said axle extension section, and tubular spacing means received through said disc mounting bolt-receiving apertures and on said mounting bolts and positioned axially intermediate said flange and said plate with said disc being slidably supported and piloted thereon; said disc apertures having sufficient radial clearance upon removal of said tubular spacing means to permit sufficient radial displacement and cocking orientation of said disc to axially remove said disc while clearing said caliper.
Claim 2
Dependent Claim
208 words
A disc brake assembly comprising: a fixed caliper; an annular axially slidable disc having a central aperture and mounting bolt-receiving apertures; an axle support member having said caliper secured thereto and taking braking torque reaction when the brake is actuated; a live axle rotatably supported in said axle support member and extending axially outward therefrom and having means thereon mounting a wheel to be braked and said disc in axially slidable and rotatably driven relation, said mounting means including a flange on said axle, an axle extension section providing a pilot for the wheel, an annular plate in axially spaced relation to said flange and drivingly secured to said axle extension section for rotation therewith, mounting bolts extending through aligned mounting boltreceiving apertures in said flange and disc and plate and wheel and spaced circumferentially about said axle extension section, and tubular spacing means received through said disc mounting bolt-receiving apertures and on said mounting bolts and positioned axially intermediate said flange and said plate with said disc being slidably supported and piloted thereon; said disc apertures having sufficient radial clearance upon removal of said tubular spacing means to permit sufficient radial displacement and cocking orientation of said disc to axially remove said disc while clearing said caliper.
Claim 3
Dependent Claim
218 words
A disc brake assembly comprising: a fixed caliper; an annular axially slidable disc having a central aperture and mounting bolt-receiving apertures; an axle support member having said caliper secured thereto and taking braking torque reaction when the brake is actuated; a live axle rotatably supported in said axle support member and extending axially outward therefrom and having means thereon mounting a wheel to be braked and said disc in axially slidable and rotatably driven relation, said mounting means including a flange on said axle, an axle extension section providing a pilot for the wheel, an annular plate in axially spaced relation to said flange and drivingly secured to said axle extension section for rotation therewith, mounting bolts extending through aligned mounting bolt-receiving apertures in said flange and disc and plate and wheel and spaced circumferentially about said axle extension section, and tubular spacing means received through said disc mounting bolt-receiving apertures and on said mounting bolts and positioned axially intermediate said flange and said plate with said disc being slidably supported and piloted thereon; said disc central aperture having sufficient radial clearance relative to said axle extension section upon removal of said mounting bolts and tubular spacing means to permit sufficient radial displacement and cocking orientation of said disc to axially remove said disc while clearing said caliper.
Claim 4
Dependent Claim
218 words
A disc brake assembly comprising: a fixed caliper; an annular axially slidable disc having a central aperture and mounting bolt-receiving apertures; an axle support member having said caliper secured thereto and taking braking torque reaction when the brake is actuated; a live axle rotatably supported in said axle support member and extending axially outward therefrom and having means thereon mounting a wheel to be braked and said disc in axially slidable and rotatably driven relation, said mounting means including a flange on said axle, an axle extension section providing a pilot for the wheel, an annular plate in axially spaced relation to said flange and drivingly secured to said axle extension section for rotation therewith, mounting bolts extending through aligned mounting bolt-receiving apertures in said flange and disc and plate and wheel and spaced circumferentially about said axle extension section, and tubular spacing means received through said disc mounting bolt-receiving apertures and on said mounting bolts and positioned axially intermediate said flange and said plate with said disc being slidably supported and piloted thereon; said disc central aperture having sufficient radial clearance relative to said axle extension section upon removal of said mounting bolts and tubular spacing means to permit sufficient radial displacement and cocking orientation of said disc to axially remove said disc while clearing said caliper.
Claim 5
Dependent Claim
205 words
A disc brake assembly comprising: a fixed caliper; an annular axially slidable disc having a central aperture and mounting bolt-receiving apertures; an axle support member having said caliper mounted thereon and taking braking torque reaction when the brake is actuated; a live axle rotatably supported in said axle support member and extending axially outward therefrom and having means thereon mounting a wheel to be braked and said disc in axially slidable and rotatably driven relation, said mounting means including a first flange on said axle provided with a pilot surface, an axle extension section having one end piloted in said first flange pilot surface, said axle extension section providing a pilot for the wheel, a second flange on said axle extension section in axially spaced relation to said first flange, mounting bolts extending through aligned mounting bolt-receiving apertures in said flanges and disc and wheel and spaced circumferentially about said axle extension section and securing said wheel to said axle extension section and said axle extension section to said live axle, and tubular spacing means received through said disc mounting bolt-receiving apertures and on said mounting bolts and positioned axially intermediate said first and second flanges with said disc being slidably supported and piloted thereon.
