Patent number: 11821481Abstract: A cable-pull actuation system for a parking brake may have a body which houses an electric motor device. A rod, adapted to operate along an actuation direction, at a first end thereof, an actuation member of a drum brake and/or of a parking brake. A transmission device may operatively connect the electric motor device to a second end of the rod which is translationally integral with a screw. The screw may be engaged with a nut screw rotationally actuated by the transmission device. A pre-loading device may act in contrast on the screw. The pre-loading device may be compressively pre-loaded to exert a pre-load traction on the rod to offset variations of load on the rod. The pre-loading device may be configured to exert a thrust action on the rod following the annulment of axial clearances for an incremental compression of the pre-loading device with respect to the pre-load value.Type: GrantFiled: April 18, 2019Date of Patent: November 21, 2023Assignee: Brembo S.p.A.Inventors: Italo Pirovano, Nicolò Mazzarini, Marco Radaelli, Tomasz Woloszyn, Alessandro Galassi

Patent number: 11754134Abstract: A device for adjusting clearance of a drum brake has an extendable strut assembly having a toothed ring and arranged between first and second shoes cooperating with a braking surface of a drum and moved by an actuating device from a resting position, in which they are distanced from the braking surface, to a braking position, in which they abut against the braking surface. The device has a first lever assembly, a second lever assembly having a coupling portion, and a connecting member having a connecting seat. The coupling portion is coupled to the connecting seat with a predetermined functional clearance. When the first and second shoes move from the resting position, the coupling portion slides in the connecting seat with an idle stroke equal to the predetermined functional clearance without transmitting motion to the connecting member and the first lever assembly. The second lever assembly transmits motion to the connecting member after the coupling portion has covered the idle stroke.Type: GrantFiled: November 25, 2020Date of Patent: September 12, 2023Assignee: Brembo S.p.A.Inventors: Tomasz Woloszyn, Marco Radaelli, Italo Pirovano

Publication number: 20230193964Abstract: A disc brake caliper has a caliper body arranged straddling a brake disc having a rotation axis defining an axial direction and opposite friction surfaces, pads accommodated in the caliper body, a cylinder forming a cylindrical wall and a bottom wall, a piston, and a parking-braking system having a rotating member accommodated within a rotation housing formed in the bottom wall. The cylinder defines a first annular housing and a second annular housing both made in the bottom wall, and extending in a direction transverse to the axial direction and leading into the rotation housing. The second annular housing is distinct from the first annular housing and positioned in a direction opposite to an inner surface of the bottom wall. The first annular housing accommodates a first seal. The second annular housing accommodates a second seal. The first and second seals act between the rotating member and the bottom wall.Type: ApplicationFiled: October 20, 2022Publication date: June 22, 2023Applicant: BREMBO S.p.A.Inventors: Marco RADAELLI, Raffaele MILANESE, Andrea MECOCCI, Tomasz WOLOSZYN, Alberto BOSIS

Patent number: 11518352Abstract: A method for actuating a parking brake system of a vehicle with at least three brake calipers associated with one or more axles of the vehicle is described. The method may include the following steps: providing at least one detection device for detecting the vehicle status, acquiring a value of the vehicle status with the detection device, comparing the detected value with a reference value of the vehicle status, and actuating two brake calipers of the at least three brake calipers if the detected value is lower than the reference value or actuating all the at least three brake calipers if the detected value is equal to or greater than the reference value.Type: GrantFiled: June 28, 2017Date of Patent: December 6, 2022Assignee: Freni Brembo S.p.A.Inventors: Andrea Bertolotti, Walter Canova, Stefano Dossi, Tomasz Woloszyn

Patent number: 7644809Abstract: A spring member for disc-brake calipers is interposed between a lateral edge of at least one pad and reaction surfaces of the caliper so as to act resiliently on the pad. The spring member comprises a ‘U’-shaped portion suitable for forming a connection with a protuberance of the reaction surfaces, a first resilient portion suitable for acting on the pad in a tangential direction, and a second resilient portion suitable for acting on the pad in a radial direction. The first and second resilient portions constitute a single body projecting from a first connection end of the first resilient portion that is connected to the ‘U’-shaped portion, so that, when the at least one pad is in a mounted configuration, it is acted on resiliently by the spring member both in a radial direction and in a tangential direction.Type: GrantFiled: July 31, 2003Date of Patent: January 12, 2010Assignee: Freni Brembo S.p.A.Inventors: Gianpaolo Cortinovis, Maurizio Mascheretti, Tomasz Woloszyn
