Abstract: A braking device has a portion having a braking surface adapted to come into contact with an opposite facing braking surface to apply a braking action, the braking surface being circumferentially free from obstacles to allow relative rotation between the braking surface and opposite facing braking surface when mutually in contact, and defining, in any point with respect to a revolution axis if the braking surface is fixed, or a rotation axis if the braking surface is rotative, an axial direction, a radial direction, a circumferential direction, and a tangential direction. A support connecting portion is radially outside the braking surface, either radially away from or outside the braking surface or either radially close to or inside the braking surface. A cooling portion, included circumferentially and laterally to the support connecting portion, has a plurality of axially through-openings adapted to increase a heat exchange surface and unadapted to create connecting surfaces.

Abstract: A valve assembly for a braking system having a master cylinder side opening, at least one caliper side opening, and at least one valve pipe, connecting the master cylinder side opening and the caliper side opening. A shutter element has a shutter body movable with respect to the valve body. When the shutter body is in a valve closing position, it interrupts a at least one main fluid passage and defines a master cylinder side pipe stretch facing a master cylinder side opening and a caliper side pipe stretch facing a caliper side opening in the valve pipe. The shutter body at least partially delimits at least one secondary fluid passage, so that, when the shutter body is in a valve closing position, the master cylinder side pipe stretch is in fluid communication with the caliper side pipe stretch only through the secondary fluid passage.

Abstract: A lever device for hydraulically actuating the brake or clutch of a vehicle equipped with a handlebar may have a pump assembly with a pump body connected to the handlebar of a vehicle. The pump body may have a cavity, a piston operatively associated with the pump body so as to be adapted to slide inside the cavity along a direction of thrust (X-X). The lever device may have a control lever assembly rotatably associated with the pump body so as to rotate about a pivot axis (Y-Y), the control lever assembly may have at least one control level. The piston defines a stroke free play between an end position and a first operating position. The lever device may have a stroke free play adjustment device which is adapted to adjust the distance along the direction of thrust (X-X) between the end position and the first operating position.

Abstract: A caliper body (1) for a disc brake unusually capable of high structural performance and low bulk, said caliper body comprising at least one connection bridge (6) arranged straddling the connection disc of an elongated attachment side portion with an elongated non-attachment side portion; in which said elongated portions have an outer surface (13, 14) opposite the disc substantially inclined and rounded towards the disc in the radially outward direction so that the caliper body (1) viewed in the tangential or circumferential direction has a bulk with a rounded outer surface like a tortoise shell.

Abstract: The invention relates to a braking disc comprising a braking band and a support bell. The band comprises first connecting means and the bell comprises second connecting means adapted to face the first connecting means. The disc further comprises coupling means, each of which is slidingly associated to one of either said first or said second connecting means and is adapted to alternatively take either a fastening position or a release position. When the coupling means are in said fastening position mutually fasten the band and the bell in the axial direction. On the other hand, when the coupling means are in said release position, they allow a mutual movement between the band and the bell in the axial direction.

Abstract: A lever device for operating a hydraulic actuator for a motorcycle, comprises a support that can be connected to a bearing structure, a hydraulic actuator connected to the support, a main lever, pivotally connected to the support and intended to be operated by being moved close to or away from said hydraulic actuator, a control rod and an adjustment member that are interposed in series between the main lever and a piston of the hydraulic actuator such as to transmit an operating movement from the lever to said piston. The adjustment member pivots about an axis of adjustment and defines a seat that accommodates an end of the control rod. The seat is eccentric to the axis of adjustment, whereby rotation of the adjustment member changes the orientation of the control rod relative to the axis of rotation of the lever, and thus the lever ratio.
