摘要:
A disc braking system (10) for a vehicle comprises a service caliper (12) suitable to be arranged astride a disc (14) rotating about an axis (16), said service caliper comprising at least one couple of service pads (18, 20). The system further comprises a floating parking caliper (30) suitable to be arranged astride the disc (14) and comprising a least one couple of parking pads (32, 34) housed in a floating structure (36) of the parking caliper. The floating structure comprises a side portion (38) and a bracket portion (40) extending from the side portion (38) in the axial direction to the disc (14). An individual mount structure (22) is provided which is suitable to be mounted on a fixed portion of the vehicle, and suitable to receive the couple of service pads (18, 20) and the floating parking caliper (30), which is slidably mounted thereon. Each parking pad (32, 34) is slidably inserted within a respective housing (48) of the mount structure (22) that is circumferentially defined by containment walls (50) being formed in the mount structure (22) and suitable to contain circumferentially opposed sides (52) of the parking pads (32, 34).
摘要:
A caliper for a disc-brake includes two side walls at a distance from each other which delimit a space to accommodate a portion of a brake disc. The side walls are connected to each other by a connecting structure which straddles the disc space. Each of the side walls delimits at least one seating capable of accommodating a pad. The caliper comprises a thrust to clamp the pads against the brake disc. The thrust is secured to the side walls in such a way that the side walls absorb the entire clamping force and the seatings are capable of securing the pads so that the side walls also absorb the entire braking moment. The connecting structure comprises arc-shaped shells, connected so as to be integral with both the side walls. The slenderness of the shells expressed as the ratio of thickness to circumferential extension relative to an axis of rotation of the brake disc is less than 17/100.

A support bracket for a disk brake of the type having a floating caliper comprises securing means for securing the support bracket to the suspension of a vehicle, and support means suitable for slidably supporting a sliding caliper body. The support bracket comprises an inner wall facing the inside of the vehicle and an outer wall opposite the inner wall and spaced therefrom. The inner wall and the outer wall are fixedly joined and arranged one on each side of a disk plane and delimit a space for accommodating a portion of a brake disk. Each of the inner wall and the outer wall forms two pad seats for accommodating pads.

摘要:
A brake pad (5) for a disc brake (1) that can be associated with a caliper (2) with thrust means (9a, 9b, 9c) for clamping the brake pad (5) with friction against a braking band (4) of a brake disc (41), wherein the brake pad (5) comprises: a plate (6) with a central portion (11) provided with a layer of friction material (7), said central portion (11) having an upper edge (12) and an opposed lower edge (13) and also two lateral edges (6a, 6b) and two support appendages (14) which extend from said lateral edges (6a, 6b) of the central portion (11), each of said support appendages (14) bounding an eye (16) capable of receiving a pin (27) of the caliper (2). The upper edge (12) and lower edge (13) extend substantially along circumferences of a circle imparting an arcuate shape to the central portion (11), and said support appendages (14) are disposed substantially at the height of said lower edge (13) of the brake pad (5).
摘要:
A caliper (1) for a disc-brake comprises two side walls (2) at a distance from each other which delimit a space (3) to accommodate a portion of a brake disc in which one of said two side walls (2) comprises means (4) for attaching the caliper (1) to a vehicle so that it is integral in rotation and in translation. The side walls (2) are connected to each other by means of a connecting structure (5) which straddles the disc space (3). Each of the side walls (2) delimits at least one seating (6) capable of accommodating a pad (7) and the caliper (1) comprises thrust means (8) to clamp the pads (7) against the brake disc, in which the thrust means (8) are secured to the side walls (2) in such a way that the latter absorb the entire clamping force and the seatings (6) are capable of securing the pads (7) in such a way that the side walls (2) also absorb the entire braking moment applicable by the pads (7) to the brake disc by friction. The connecting structure (5) comprises one or more shells (10, 11), arc-shaped or arranged along an arc, connected so as to be integral with both the side walls (2) along one of their outer circumferential edges (12) and the slenderness of these one more shells (10, 11) expressed as the ratio of thickness to circumferential extension relative to an axis of rotation of the brake disc is less than 17/100.
