  • Publication number: 20240125364
    Abstract: A pad-holding spring and pad return spring assembly for a brake caliper may have a caliper body adapted to be arranged straddling a brake disc and a one pad-holding spring configured to be arranged between at least one guiding ear of a brake pad housed in the caliper body and the caliper body to bias the brake pad, and a pad return spring configured to bias the brake pad away from a brake disc. The pad-holding spring may have one C-shaped section. The pad return spring may have an anchoring portion operatively connected to the C-shaped section, a coupling portion configured to couple the brake pad, and a linking arm.

  • Publication number: 20240110603
    Abstract: A band spring arranged straddling a brake disc to apply an elastic action on a brake pad to bias the brake pad away from the brake disc is provided. The brake pad has a backing plate supporting friction material and having a plate edge forming at least one thrust portion and at least one striker portion. The band spring has a band-shaped spring body and three portions, at least two of which mutually distinct, namely a first coupling portion coupling the band spring to a caliper body, a second thrust portion applying an elastic action on the at least one thrust portion and a third abutment portion forming a support that prevents sliding of the second thrust portion when the band spring is subject to external actions, the third abutment portion, when abutting against the striker portion being biased by a peak or buckling load, avoiding that the band spring permanently couples with the brake pad.

  • Publication number: 20240003391
    Abstract: A caliper body, pin and an elastic element assembly having a caliper body, a brake pad supporting pin, and an elastic element is provided. The elastic element is fitted on the brake pad supporting pin. The brake pad supporting pin has portions that can be accommodated in a caliper body first housing and in a caliper body second housing made in the caliper body without interfering in an axial direction with surfaces of the caliper body having an extension in a radial direction. The elastic element is accommodated in a first housing first portion of the caliper body first housing. The elastic element abuts against a first housing abutment portion to define a limit stop of the brake pad supporting pin in the caliper body.

  • Publication number: 20230417298
    Abstract: A pad-holding and pad return spring assembly has a pad-holding spring arranged between a guiding ear of a brake pad and a support, and a pad return spring. The pad-holding spring has a C-shaped section having a central portion adapted to be inserted into a recess of the support and to accommodate the guiding ear. The pad return spring has an anchoring portion connected to the C-shaped section extending in axial direction in a first orientation opposite to a brake disc, and an elastic return arm connected to the anchoring portion and having an elastic return arm end for engaging the brake pad. The elastic return arm develops along an elastic return arm longitudinal direction oriented in the axial direction with a second orientation concordant with the brake disc, is elastically movable between an advanced position and a resting position and in operation is spaced from the pad-holding spring and the anchoring portion.

  • Publication number: 20230407932
    Abstract: A brake pad pin and axially constraining elastic element assembly has a supporting pin having a pin body that has a pin first portion having a pin first portion diameter and a pin second portion having a pin second portion diameter greater than the pin first portion diameter. An elastic element has an elastic element inner diameter and an elastic element outer diameter either greater than or equal to the pin second portion diameter. The elastic element inner diameter is smaller than the pin second portion diameter. A pin third portion has a pin third portion stretch having a pin third diameter greater than the elastic element inner diameter. The elastic element has an elastic element inner profile. The pin third portion has a pin third portion profile connecting the pin first and second portions and is biased towards the elastic element. The pin third portion profile is wedged into the elastic element inner profile.

  • Patent number: 11802601
    Abstract: A spring for friction pads which can be associated with a caliper of a disc brake to bias the friction pads elastically away from a brake disc may have a central stretch and two opposite transverse stretches, extending from the central stretch in two opposite transverse directions and each forming a supporting stretch, a resting stretch and a wing stretch extending between the supporting stretch and the resting stretch. The supporting stretches lie on the same supporting plane and the wing stretch may have an ascending wing stretch and a descending wing stretch. The spring may also have one or more fixing stretches connected to the central stretch and forming at least two opposite fixing stretches for elastic snap fixing to corresponding fixing seats of the caliper.

  • Patent number: 11401990
    Abstract: A spring device for a disc brake, a pad and spring assembly for a disc brake, a brake caliper, and a disc brake is described. The spring device may have a spring body having prevalently longitudinal development, with at least one coupling portion, to couple in a snapping manner the spring device to a portion of an associable brake caliper in a removable manner. The spring pad assembly may have at least one brake pad having at least one ramp surface, inclined with respect to the radial direction and to the tangential direction, which forms an abutment reference for the at least one thrust surface of the spring device. The at least one ramp surface of the support plate puts in traction the spring device.
