Abstract
Abstract A partial lining disk brake, preferably with a floating saddle whose brake cushions are adapted to be supported at the inlet and/or outlet side by mutually opposite projections which are axially displaceably guided in recesses relative to the brake body by at least one nose preferably arranged in the center between the supports; the nose thereby engages with a counter support surface thereof in a notch matched thereto while the base surface of the notch is supported on the radially outer-surface of the nose.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
496 words
A partial lining disk brake comprising: a brake disc means, brake body means including a first pair of spaced leg portions extending transversely of the axis of rotation of said brake disc means on respective sides thereof and a second pair of leg portions extending substantially parallel to the axis of rotation of said brake disc means and connecting the respective ends of said first pair of leg portions, side guide rails provided on said brake body means on each side of said brake disc means at an inlet and outlet side of said brake body means with respect to the direction of rotation of said brake disc means, said side guide rails opening toward each other and extending in the direction of the axis of rotation of the brake disc means, brake cushion means disposed on each side of said brake disc means, each of said brake cushion means including brake lining means and lining carrier means for supporting said brake lining means, said lining carrier means including an upper edge portion disposed at the periphery of the brake disc means, a lower edge portion disposed radially inwardly of said upper edge portion in the direction of the axis of rotation of said brake disc means, and lateral edge portions connecting the respective ends of said upper and lower edge portions. projection means provided on each lateral edge portion of each of said lining carrier means at the lower edge portion thereof, said projection means forming a minor portion of said lining carrier means, each of said projection means being disposed in a respective side guide rail so as to be axially displaceably guided therein, intermediate guide means provided on said brake body means at the lower edge portion of said lining carrier means, said intermediate guide means including guide surface means disposed at an axial center plane of the brake which extends vertially through the axis of rotation of the brake disc means, said guide surface means including first and second support surfaces disposed on respective sides of the axial center plane of the brake and spaced thErefrom and a third support surface connecting the free ends of said first and second support surfaces, intermediate recess means provided on each of said lining carrier means along the lower edge thereof between said side projection means, said intermediate recess means including intermediate guide counter support surfaces which are engageable with said support surfaces of said intermediate guide means, a floating saddle means displaceably mounted on said brake body means, said floating saddle means including an upper edge portion disposed at the periphery of the brake disc means and a lower edge portion disposed radially inwardly of said upper edge portion in the direction of the axis of rotation of said brake disc means, and recess means provided in said floating saddle means at the lower edge thereof, said recess means including guide counter support surfaces engageable with said support surfaces of said intermediate guide means.
Claim 2
Dependent Claim
496 words
A partial lining disk brake comprising: a brake disc means, brake body means including a first pair of spaced leg portions extending transversely of the axis of rotation of said brake disc means on respective sides thereof and a second pair of leg portions extending substantially parallel to the axis of rotation of said brake disc means and connecting the respective ends of said first pair of leg portions, side guide rails provided on said brake body means on each side of said brake disc means at an inlet and outlet side of said brake body means with respect to the direction of rotation of said brake disc means, said side guide rails opening toward each other and extending in the direction of the axis of rotation of the brake disc means, brake cushion means disposed on each side of said brake disc means, each of said brake cushion means including brake lining means and lining carrier means for supporting said brake lining means, said lining carrier means including an upper edge portion disposed at the periphery of the brake disc means, a lower edge portion disposed radially inwardly of said upper edge portion in the direction of the axis of rotation of said brake disc means, and lateral edge portions connecting the respective ends of said upper and lower edge portions. projection means provided on each lateral edge portion of each of said lining carrier means at the lower edge portion thereof, said projection means forming a minor portion of said lining carrier means, each of said projection means being disposed in a respective side guide rail so as to be axially displaceably guided therein, intermediate guide means provided on said brake body means at the lower edge portion of said lining carrier means, said intermediate guide means including guide surface means disposed at an axial center plane of the brake which extends vertially through the axis of rotation of the brake disc means, said guide surface means including first and second support surfaces disposed on respective sides of the axial center plane of the brake and spaced thErefrom and a third support surface connecting the free ends of said first and second support surfaces, intermediate recess means provided on each of said lining carrier means along the lower edge thereof between said side projection means, said intermediate recess means including intermediate guide counter support surfaces which are engageable with said support surfaces of said intermediate guide means, a floating saddle means displaceably mounted on said brake body means, said floating saddle means including an upper edge portion disposed at the periphery of the brake disc means and a lower edge portion disposed radially inwardly of said upper edge portion in the direction of the axis of rotation of said brake disc means, and recess means provided in said floating saddle means at the lower edge thereof, said recess means including guide counter support surfaces engageable with said support surfaces of said intermediate guide means.
Claim 3
Dependent Claim
61 words
A partial lining disk brake according to claim 1, wherein said recess means and said intermediate guide means are arranged such that during actuation of the brake one projection means remains free from contact with a corresponding one of said side guide rails in such a manner that the brake lining means can be forced evenly against said brake disk means.
Claim 4
Dependent Claim
20 words
A partial lining disk brake according to claim 2, wherein said side guide rails are constructed of relatively great length.
Claim 5
Dependent Claim
25 words
A partial lining disk brake according to claim 3, wherein the ratio of width to length of said guide rails is about 1 : 10.
Claim 6
Dependent Claim
33 words
A partial lining disk brake according to claim 1, wherein said recess means are generally U-shaped in cross-section with the open end thereof facing the axis of rotation of the brake disk means.
Claim 7
Dependent Claim
43 words
A partial lining disk brake according to claim 5, wherein said recess means and said intermediate guide means are so arranged that during actuation of the brake one projection means remains free from contact with a corresponding one of said side guide rails.
Claim 8
Dependent Claim
21 words
A partial lining disk brake according to claim 1, wherein said side guide rails are constructed of a relatively great length.
Claim 9
Dependent Claim
26 words
A partial lining disk brake according to claim 7, wherein the ratio of width to length of said side guide rails is about 1 : 10.
