Abstract
A floating caliper may have a caliper body where the caliper body is movably supported in an axial direction on at least at one guide pin. The guide pin may have a pin sliding portion. The caliper body may have a pin seat, which slidingly accommodates a portion of the pin sliding portion. The floating caliper may also have a sealing arrangement between the pin seat and the guide pin. A sealing arrangement outer surface or a sealing arrangement inner surface may have an axial extension, which is smaller than a pin seat axial extension or the length of the pin sliding portion, respectively, creating, in at least one position of the floating caliper during the axial sliding thereof, at least one sealing arrangement channel between the sealing arrangement and the pin seat or the pin sliding portion.
Claims11
A floating caliper, comprising:
- a caliper body arranged straddling a brake disc, said brake disc rotating about a rotation axis which defines an axial direction, a radial direction orthogonal to said axial direction, and a circumferential direction orthogonal to both said axial direction and said radial direction;
- wherein said caliper body is movably supported in axial direction at at least one guide pin;
- said at least one guide pin comprises a pin sliding portion of predetermined pin axial extension;
- said caliper body comprises a pin seat which slidingly accommodates a portion of said pin sliding portion;
- said pin seat has a predetermined pin seat axial extension said floating caliper further comprises a sealing arrangement interposed between said pin seat and said guide pin;
- said sealing arrangement comprises a tubular-shaped sealing arrangement body made in one piece which crosses said entire pin seat;
- said sealing arrangement comprises a sealing arrangement outer surface, a portion of which is in contact with said pin seat;
- said sealing arrangement comprises a sealing arrangement inner surface, a portion of which is in contact with said pin sliding portion;
- wherein the portion of the sealing arrangement outer surface that is in contact with said pin seat is substantially longer than the portion of the sealing arrangement inner surface that is in contact with the pin sliding portion, thus creating at least one sealing arrangement channel between said sealing arrangement and said pin sliding portion;
- wherein said at least one sealing arrangement channel is open to come out of said pin seat;
- and
- wherein said sealing arrangement channel is adapted to receive at least one coupling portion therein;
- wherein in an operating condition the at least one coupling portion, or a pin coupling seat, is adapted to be radially aligned below the sealing arrangement channel.
A floating caliper, comprising:
- a pin seat,
- a pin sliding portion,
- a sealing arrangement,
- wherein said sealing arrangement comprises at least one coupling portion,
- wherein said sealing arrangement is directly attached to said pin sliding portion via the at least one coupling portion,
- wherein at least one portion of an outer portion of said sealing arrangement is in direct facing contact with the pin seat,
- wherein at least one portion of an inner portion of said sealing arrangement is in direct facing contact with the pin sliding portion,
- wherein said at least one portion of said outer portion of said sealing arrangement that is in direct facing contact with the pin seat is longer than said at least one portion of said inner portion of said sealing arrangement that is in direct facing contact with said pin sliding portion, and
- a sealing arrangement channel,
- wherein said sealing arrangement channel is adapted to slide axially and receive the at least one coupling portion therein so that the at least one coupling portion is adapted to be radially aligned below the sealing arrangement channel.
