A disc brake caliper has a caliper body and a pair of pads and, in each side portion of the caliper body, a distal piston and a proximal piston, having radially distanced and aligned pressure centers.

Disc brake caliper, method for manufacturing a caliper and caliper spring

Disc brake calliper

Flexible sheathing for the protection of piston-cylinder units for disc brakes are provided. Such flexible sheathing may be arranged in a retracted condition wherein the piston is completely accommodated within the cylinder and in an extended condition wherein the piston is completely extracted from a caliper body defining the cylinder. Pistons incorporating such flexible sheathings and calipers incorporating such pistons are also provided.

Protective sheathings for disc brake piston-cylinder units

The invention relates to a brake pad () of a disc brake () comprising a support plate () having a thrust surface () to receive the thrust of at least one piston, and a friction surface () to which a friction portion () is associated, associated to said support plate () to rest on a friction surface () of said brake disc (), said pad comprising a support plate edge () which delimits said thrust surface () and friction surface (), said thrust plate edge () comprising an upper edge portion (), substantially facing or directed outwards in the outward sense (RE) of said radial direction (R-R), said thrust plate edge () comprising an upper edge portion (), substantially facing or directed in the inward sense (RI) of said radial direction (R-R), said thrust plate edge () comprising two lateral edge portions () opposite each other and substantially facing or directed in the tangential direction (T-T), said lateral edge portions () each comprising a lower lateral edge sub-portion (), next to the lower edge portion (), which extends by an extension less than or equal to a third of the longitudinal extension of said lateral edge portion (), wherein said upper edge portion () of said thrust plate edge () comprises at least one tab () forming a seat (), open or closed, and defining a spring surface () facing or directed substantially in an inward direction (RI) in said radial direction (R-R), to receive and support a thrust portion () of a spring device () adapted to stress the brake pad with at least one direct thrust component in the outward direction (RE) of said radial direction (R-R), and wherein all along said upper edge portion () there is no upper support portion of the caliper body (), superiorly avoiding the support of the plate or of the pad by the caliper body () to exert a reaction to the thrust component having an outward sense (RE) of said radial direction (R-R) to the stress action of the spring device (); and wherein a portion of the support plate () which is delimited by said lower lateral edge sub-portion (), and/or by said lower edge portion (), comprises a lower portion resting on the support plate () of the caliper body, defining a caliper support surface resting on the support plate of the caliper body to exert a reaction to the thrust component of the spring device (); and wherein said caliper support surface () substantially faces, or has a sense, in the outward sense (RE) of said radial direction (R-R) to rest directly or indirectly on the caliper body (), so that said pad is pulled radially outwards substantially in its entire radial extension, in the outward sense (RE).

Disc brake pad, spring for disc brake caliper and disk brake caliper assembly

A caliper for disc brake comprising a caliper body housing at least one pair of pads disposed on opposite sides along an axial direction and comprising at least one thrust piston which interfaces with the pad so as to press it against the associable brake disc, and at least one return spring that exerts a return thrust on the support plate of the pad. The return spring comprises a fixing portion to the caliper body that extends from axially opposite sides in separate thrust branches, each thrust branch interfacing with a support plate of a related pad. Each thrust branch comprises a first rectilinear portion that extends towards the corresponding pad, a curved portion, integral with the first rectilinear portion and folded in approach to the fixing portion, a second rectilinear portion that extends from the curved portion in approach to the fixing portion. The second rectilinear portion terminates with a free cantilevered end and interfaces with an edge of the support plate.

Caliper for disc brake

Disc brake caliper

A caliper body () of a disc brake caliper, said body being adapted to arrange astride of a brake disc, said body () comprising a first () and a second () wheel side elongated portion, the second wheel side portion comprises at least one wheel side opening () which places a channel for receiving the disc in communication with the outside of the wheel side caliper body (), and wherein 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.

Caliper body for disk brake

The invention illustrates a caliper body () for a disc brake, suitable for being arranged astride of a disc () for a disc brake, said disc () defining a first braking surface () and a second braking surface () opposite the first braking surface (); said caliper body () comprising a first half-caliper () and a second half-caliper (), which are obtained by casting without machining and are suitable for being connected together at respective contact surfaces () defining a joining plane (P) of the half-calipers; said first half-caliper () comprising a wheel-side elongated portion (), extending in a tangential direction, which is suitable for facing an axially inner surface thereof towards the first braking surface (), and at least one first projecting portion (), projecting in an axial direction provided with a first contact surface () suitable for connecting with the second half-caliper (); said second half-caliper () comprising a vehicle-side elongated portion (), extending in a tangential direction, which is suitable for facing an axially inner surface towards the second braking surface (), an attachment portion () suitable for being connected to a support for the caliper and at least one second projecting portion (), projecting in an axial direction provided with a second contact surface (&#x2033;) suitable for connecting with the first half-caliper (); the first projecting portion () and the second projecting portion () being suitable for being connected together at the respective contact surfaces (&#x2033;) so as to form at least one bridge astride of the disc (); each of said first projecting portion () and said second projecting portion () being provided with a radially inner surface (&#x2033;) suitable for facing the disc () that forms an angle &#x3b1; of between 90&#xb0; and 92&#xb0; with the respective contact surface (&#x2033;); in which the first projecting portion () extends farther in the axial direction with respect to the second projecting portion () so that said half-caliper joining plane (P) is axially closer to the vehicle-side elongated portion () with respect to the wheel-side elongated portion ().
