Abstract: The present invention relates to a drive device (100) of a brake caliper (200), comprising a recirculating ball screw-nut assembly within a cylinder chamber (140) in a caliper body (145), wherein the recirculating ball screw-nut assembly comprises a threaded shaft (150) and a nut (160) screwed externally onto the threaded shaft (150), with external teeth (165) of the nut screw, wherein the threaded shaft (150) and the nut screw (160) extend in the direction of a drive axis (170) coaxial to the threaded shaft (150), and wherein the threaded shaft (150) extends in a direction of extension from a front end thereof to a rear end thereof to a thrust plate (180), in which an axial retaining ring (110) of the nut screw (160) is interposed between the external teeth (165) and the thrust plate (180) and held in position with the use of at least one fixing screw (120) comprising at least one respective tip (125), in which the axial retaining ring (110) has an inclined surface (111) on which a tapered side (121) of a

Abstract: A brake caliper has a caliper body having two side walls delimiting a disc space for accommodating a portion of a brake disc, a connection structure extending straddling the disc space and connecting the side walls to each other, and a pad housing for accommodating at least one pad. A transmission housing is connected to the caliper body so that a front wall of the transmission housing faces the disc space. Thrust members bias the pads against the brake disc along an actuation axis. A control housing supports and houses an electric motor having a drive shaft. and configured to generate and transfer mechanical power to the thrust members. A brake control unit controls the electric motor. The drive shaft protrudes from a front side of the electric motor facing the caliper body. The brake control unit has an electronic board extending in a transverse direction with respect to the actuation axis.

Abstract: An actuation device for a brake disc has a recirculating ball screw-nut screw assembly and a thrust bearing. The recirculating ball screw-nut screw assembly has a threaded shaft and a nut screw screwed onto the threaded shaft. The threaded shaft and the nut screw extend in direction of an actuation axis. The threaded shaft extends between a front end and a rear end of the threaded shaft. The nut screw receives a torque generatable by a gearmotor. A rotation of the nut screw with respect to the threaded shaft results in a translation of the threaded shaft with respect to the nut screw in the direction of the actuation axis. The thrust bearing provides a reaction rest for the nut screw in the direction of the actuation axis. The thrust bearing is positioned within an extension of the threaded shaft between the front and rear ends of the threaded shaft.

Abstract: An assembly (1) for detecting the wear of a brake pad of a disk brake, wherein said assembly comprises at least one sensor body (2) and at least one spring (4), said assembly being suitable for cooperating with said pad (10) which comprises a support plate (11), suitable for being supported by the disk brake, and to which there is associated friction material (12), suitable for to coming into contact with braking surfaces of a disk-brake disk, and wherein said at least one sensor body (2) is coupled geometrically to said support plate (11), said at least one spring (4) surrounding said at least one sensor body (2) so that said at least one spring (4) is positioned in said geometric coupling between said at least one sensor body (2) and said plate (11) and presenting projections (41) for the snap-coupling to said support plate (11), and wherein said at least one spring (4) has indentations (42) bent towards the at least one sensor body (2) for constraining said at least one spring (4) to said at least one sens
