Brake caliper housing
A brake caliper housing includes a first end wall, a second end wall, and a transverse wall that extends from the first end wall to the second end wall. The brake caliper housing includes a first bearing protrusion that extends from the first end wall and the transverse wall, and that defines a first lateral bearing surface and a first arcuate bearing surface that extends from the first lateral bearing surface.
1. A brake caliper housing comprising:
a first end wall;
a second end wall disposed opposite the first end wall;
a transverse wall that extends from the first end wall to the second end wall;
an interface wall that extends from the first end wall, the second end wall, and the transverse wall, the interface wall cooperating with the first end wall, the second end wall, and the transverse wall to at least partially define a cavity and the interface wall defining an opening of the cavity;
a saddle bearing protrusion that extends from the transverse wall;
a first bearing protrusion that extends from the first end wall and the transverse wall, the first bearing protrusion defining a first lateral bearing surface that is disposed substantially parallel to the first end wall and a first arcuate bearing surface that extends from the first lateral bearing surface; and
a second bearing protrusion that extends from the first end wall, the second bearing protrusion defining a second lateral bearing surface that is substantially coplanar with the first lateral bearing surface and a second arcuate bearing surface that extends from the second lateral bearing surface, wherein the first lateral bearing surface and the second lateral bearing surface are adapted to support an operating shaft.
2. The brake caliper housing of claim 1 wherein the first lateral bearing surface is spaced apart from the first end wall.
3. The brake caliper housing of claim 1 wherein the first arcuate bearing surface is spaced apart from the transverse wall.
4. The brake caliper housing of claim 1 wherein the first arcuate bearing surface is radially disposed with respect to a transverse axis that intersects the first end wall and the second end wall.
5. The brake caliper housing of claim 4 wherein the first lateral bearing surface is disposed perpendicular to the transverse axis.
6. The brake caliper housing of claim 4 wherein the first bearing protrusion is completely disposed below the transverse axis.
7. The brake caliper housing of claim 4 wherein the first lateral bearing surface intersects the first arcuate bearing surface along a continuously curved line.
8. The brake caliper housing of claim 1 wherein the first bearing protrusion is spaced apart from the second bearing protrusion, the first bearing protrusion is disposed below a transverse axis that intersects the first end wall and the second end wall, and the second bearing protrusion is disposed above the transverse axis.
9. The brake caliper housing of claim 8 wherein the second bearing protrusion is completely disposed above the transverse axis.
10. The brake caliper housing of claim 1 wherein the second lateral bearing surface is spaced apart from the first end wall.
11. The brake caliper housing of claim 1 wherein the second arcuate bearing surface is spaced apart from the transverse wall.
12. The brake caliper housing of claim 1 further comprising an upper surface, wherein the second bearing protrusion extends from the upper surface toward the first bearing protrusion.
13. The brake caliper housing of claim 8 wherein the first arcuate bearing surface and the second arcuate bearing surface are disposed a common radial distance from the transverse axis.
14. The brake caliper housing of claim 1 wherein the first lateral bearing surface is parallel to the second lateral bearing surface.
15. The brake caliper housing of claim 1 further comprising a second saddle bearing protrusion that extends from the transverse wall, wherein the first bearing protrusion and the second bearing protrusion are axially positioned between the saddle bearing protrusion and the first end wall and the second saddle bearing protrusion is axially positioned between the saddle bearing protrusion and the second end wall.
16. The brake caliper housing of claim 1 wherein the saddle bearing protrusion extends from the transverse wall and the first bearing protrusion is axially disposed between the saddle bearing protrusion and the first end wall.
17. The brake caliper housing of claim 1 further comprising a first mounting pad and a second mounting pad that is spaced apart from the first mounting pad, wherein the first mounting pad and the second mounting pad each have a through hole that is adapted to receive a fastener for mounting a bridge to the brake caliper housing.
18. The brake caliper housing of claim 17 further comprising a connecting surface that extends from the first mounting pad to the second mounting pad, wherein the connecting surface is spaced apart from the bridge.
19. The brake caliper housing of claim 18 wherein the caliper housing has a second saddle bearing protrusion that extends from the transverse wall and is spaced apart from the saddle bearing protrusion, the first bearing protrusion, the second bearing protrusion, the first end wall, and the second end wall.
20. The brake caliper housing of claim 18 further comprising a step surface that extends from the connecting surface to the first mounting pad and the second mounting pad.
