Abstract

The present invention in one or more embodiments provides a roller tool for roughening a friction ring of a brake disk, the roller tool including a roller body including inner and outer ends and a casing surface positioned there-between, the inner end differing in cross-section dimension than the outer end, the casing surface including thereupon one or more protrusions for contacting the friction ring. The roller tool may further include a support frame supporting the roller body. The support frame may include a short leg connected to the outer end of the roller body and a long leg connected to the inner end of the roller body.

First claim

What is claimed is:

1 . A roller tool to roughen a friction ring of a brake disk, comprising:
a roller body including inner and outer ends and a casing surface positioned there-between, the inner end differing in cross-section dimension than the outer end; and one or more protrusions supported on the casing surface and to contact the friction ring.

2 . The roller tool of claim 1 , further comprising a support frame supporting the roller body.

3 . The roller tool of claim 2 , wherein the support frame includes a short leg connected to the outer end of the roller body and a long leg connected to the inner end of the roller body.

4 . The roller tool of claim 3 , further comprising an arm connecting the short and long legs.

5 . The roller tool of claim 1 , wherein the inner end is of an inner end circumference and the outer end is of an outer end circumference differing in value than the inner end circumference.

6 . The roller tool of claim 5 , wherein a ratio of the outer end circumference of the roller body relative to an outer ring circumference of the friction ring is equal to a ratio of the inner end circumference of the roller body relative to an inner ring circumference of the friction ring.

7 . The roller tool of claim 1 , wherein the casing surface is of a longitudinal dimension defined between the inner and outer ends, the longitudinal dimension being no smaller in value than a radial dimension of the friction ring.

8 . The roller tool of claim 1 , wherein the one or more protrusions are at least partially receivable within one or more recessed portions of the friction body.

9 . The roller tool of claim 1 , wherein the one or more protrusions differ in material than the casing surface.

10 . The roller tool of claim 1 , wherein the one or more protrusions include a first protrusion and a second protrusion positioned next to and spaced apart from the first protrusion, the first protrusion being at least partially receivable within a first recessed portion of the friction ring, and the second protrusion contacting a rib surface of a rib of the friction ring, the rib being positioned between the first recessed portion and a second recessed portion of the friction ring.

11 . A roller tool to roughen a friction ring of a brake disk, comprising:
a roller body including inner and outer ends and a casing surface positioned there-between, the inner end differing in cross-section dimension than the outer end; one or more protrusions supported on and differing in material than the casing surface; and a support frame supporting the roller body.

12 . The roller tool of claim 11 , wherein the support frame includes a short leg connected to the outer end of the roller body and a long leg connected to the inner end of the roller body.

13 . The roller tool of claim 12 , further comprising an arm connecting the short and long legs.

14 . The roller tool of claim 11 , wherein the inner end is of an inner end circumference and the outer end is of an outer end circumference differing in value than the inner end circumference.

15 . The roller tool of claim 14 , wherein a ratio of the outer end circumference of the roller body relative to an outer ring circumference of the friction ring is equal to a ratio of the inner end circumference of the roller body relative to an inner ring circumference of the friction ring.

16 . The roller tool of claim 11 , wherein the casing surface is of a longitudinal dimension defined between the inner and outer ends, the longitudinal dimension being no smaller in value than a radial dimension of the friction ring.

17 . The roller tool of claim 11 , wherein the one or more protrusions are at least partially receivable within one or more recessed portions of the friction body.

18 . The roller tool of claim 11 , wherein the one or more protrusions include a first protrusion and a second protrusion positioned next to and spaced apart from the first protrusion, the first protrusion being at least partially receivable within a first recessed portion of the friction ring, and the second protrusion contacting a rib surface of a rib of the friction ring, the rib being positioned between the first recessed portion and a second recessed portion of the friction ring.

19 . A roller tool to roughen a friction ring of a brake disk, comprising:
a roller body including inner and outer ends and a casing surface positioned there-between, the inner end being of an inner end circumference and the outer end being of an outer end circumference differing in value than the inner end circumference; one or more protrusions supported on the casing surface and to contact the friction ring; and a support frame supporting the roller body, the support frame including a short leg, a long leg, and an arm connecting the short and long legs, the short and long legs being respectively connected to the outer and inner ends of the roller body.

20 . The roller tool of claim 19 , wherein the one or more protrusions differ in material than the casing surface.
