CALIPER BODY FOR DISK BRAKE

摘要

A caliper body (1) of a disc brake caliper, said body being adapted to arrange astride of a brake disc, said body (1) comprising a first (5) and a second (11) wheel side elongated portion, the second wheel side portion comprises at least one wheel side opening (21; 22; 45) which places a channel for receiving the disc in communication with the outside of the wheel side caliper body (23), and wherein said at least one opening (21; 22; 45) is an axial central opening (45) which places said channel for receiving the disc in communication with the outside of the wheel side caliper body (23), and wherein said axial central opening (45) has a closed edge which delimits said opening at a face thereof substantially in axial direction, and wherein said at least one axial central opening (45) is arranged at least partially substantially radially overlapping at least one wheel side cylinder (12; 33), wherein said at least one axial central opening (45) is arranged substantially in the center of said second wheel side elongated portion.

1. Caliper body of a disc brake caliper, said body being adapted to arrange astride of a brake disc having a first braking surface, or vehicle side braking surface, and an opposite second braking surface, or wheel side braking surface, said surfaces being coaxial to an axis of rotation of the disc defining an axial direction, an orthogonal direction radial to the disc, and an orthogonal circumferential or tangential direction, said caliper body comprising:
a first vehicle side elongated portion adapted to face said first braking surface of the brake disc, said elongated portion comprising at least one first vehicle or cylinder side piston seat adapted to seat a first piston which may be biased with a brake fluid exiting from said cylinder for influencing a first pad adapted to be seated within said caliper body between said first vehicle side elongated portion and said first braking surface for abutting against said first braking surface and exerting a braking action on the brake disc, said vehicle side elongated portion having a longitudinal extension in circumferential direction and comprising a first disc input side end and an opposite second disc output side end, said body further comprising an opposite second wheel side elongated portion adapted to face said opposite second braking surface of the brake disc, said elongated portion comprising at least one second wheel or cylinder side piston seat adapted to seat a second piston which may be biased with a brake fluid exiting from said cylinder for influencing a second opposite pad adapted to be seated within said caliper body between said second wheel side elongated portion and said opposite second braking surface for abutting against said second braking surface and exerting a braking action on the brake disc, said wheel side elongated portion having a longitudinal extension in circumferential direction and comprising a first disc input end and an opposite second disc output end, said body further comprising a first disc input end bridge adapted to arrange astride of the brake disc and to connect said first vehicle side disc input end of said first vehicle side elongated portion with said first wheel side disc input end of said second wheel side elongated portion, said body further comprising a second disc output end bridge adapted to arrange astride of the brake disc and to connect said second vehicle side disc output end of said first vehicle side elongated portion with said second wheel side disc output end of said second wheel side elongated portion, said first and second elongated portions and said first and second end bridges forming a yoke which delimits a channel for receiving a portion of the brake disc which is adapted to receive a sector of the brake disc placing the caliper body astride thereof, wherein said second wheel side elongated portion comprises at least one wheel side opening which places said channel for receiving the disc in communication with the outside of the wheel side caliper body, characterised in that said at least one opening is an axial central opening which places said channel for receiving the disc in communication with the outside of the wheel side caliper body, and wherein said axial central opening has a closed edge which delimits said opening at a face thereof substantially in axial direction, and wherein said at least one axial central opening is arranged at least partially substantially radially overlapping at least one wheel side cylinder, wherein said at least one axial central opening is arranged substantially in the center of said second wheel side elongated portion.
