A one-piece brake carrier for a vehicle disc brake is provided. The brake carrier has a frame-like disc wrap-around element which has two mutually parallel bridge struts, and two frame sections arranged parallel to a brake disc rotation axis and connecting the bridge struts. The brake carrier further has a securing flange by which the brake carrier is fixable to an axle flange. One or both of the frame sections, starting from a side of the brake carrier away from the securing flange widens toward an outer edge of the securing flange.

A disc brake for a utility vehicle, with a brake caliper which overlaps a brake disc, is preferably designed as a sliding caliper, is fastened to a positionally fixed brake carrier and has a central caliper opening above the brake disc, with an application device for applying the brake, and with two brake pads which are insertable through the caliper opening and each have a pad carrier and a friction pad fastened thereto, of which brake pads the one brake pad, as an application-side brake pad, can be pressed against the brake disc on the one side of the brake disc by the application device, and the other, as a reaction-side brake pad, is arranged on the opposite side of the brake disc, is distinguished in that a holding-down clamp is provided which is designed in such a manner that it radially secures only one of the two brake pads in the pad slot.

A disc brake for a utility vehicle is provided, having a sliding brake caliper which is fastened to a brake carrier and has a central opening above a brake disc. Two brake pads are acted on by at least one restoring device with resilient spreading elements which engage the brake pads and acts equally against the respective tightening direction. The spreading device is arranged in the central opening such that the spreading elements engage directly or indirectly outside the friction linings in the center region of the pad backing plates or at at least two contact regions of the brake pads arranged at a distance from each other with respect to the center. The contact regions each have a contact surface and a bearing surface, on which the spreading elements are movably arranged. The invention further relates to a corresponding brake pad set.

Disclosed is a disc brake including a stationary support arm which includes a C-shaped recess, a slide which fits closely to the walls of the recess, a brake pad including two lateral lugs, each of which is received in a recess with a slide inserted therebetween, and a spring for resiliently returning the brake pad to its inoperative position, including a portion for attachment to the stationary support. The attachment portion includes an attachment tab, at least one flange of the slide includes an attachment strip, and the attachment tab and the attachment strip include complementary element for connection by form-fitting interaction.

A disc brake for a utility vehicle is provided. The disc brake includes a brake caliper overlapping a brake disc, the brake caliper being held on a brake carrier located on the vehicle in an axially displaceable manner with respect to the brake disc. The brake carrier has brake lining slots on opposite sides of the brake disc defined by brake carrier lugs on the entry and the exit side. Each slot receives a brake lining having a brake plate and a friction lining fastened thereto, configured such that each brake lining is supported at least at the entry side in the direction of rotation of the brake disc on the entry side brake carrier lug during braking.

The invention relates to a disc brake comprising a brake caliper (1), which engages over a brake disc that can rotate on an axis (A) and brake linings (2, 3) arranged on both sides thereof in a lining groove (6), comprising a hold-down arrangement (8) formed by a rigid hold-down piece (7) and a leaf spring (9) and leading transversely over the brake linings (2, 3), wherein the hold-down piece (7) has a central section (7b) forming the majority of its total length and leading over the lining groove (6), and two end sections (7a, 7c), wherein the hold-down piece is supported against the brake linings (2, 3) towards the disc brake axis (A), and wherein said hold-down piece extends at least partially into a slot (14) of the brake caliper (1) with the first end section (7a) thereof, and wherein the leaf spring (9) extends in the longitudinal direction of the hold-down piece (7) and is spring-elastically supported against the outer side of the hold-down piece (7) facing away from the brake linings (2, 3). In order to more simply configure the fixing of the elements of the hold-down arrangement in terms of assembly and production, without thereby weakening the fixture, the first end section (7a) of the hold-down piece (7) is angled in relation to the central section (7b).

A disc brake pad includes a lining and a back plate supporting a back surface of the lining. A first torque transmitting portion, which transmits a brake tangential force that acts toward one circumferential side at a time of braking, is provided at a part of the back plate projecting radially outward from an outer peripheral edge of the lining. A second torque transmitting portion, which transmits a brake tangential force that acts toward the other circumferential side at the time of braking, is provided at a part of the other circumferential end portion of the back plate that is located radially inward from an action line of the brake tangential force acting at the time of braking.

In this disc brake, a pair of brake pads has recesses in the outer peripheral surfaces thereof. A pad spring has a first pressing section extending axially and provided to a base, the first pressing section pressing, toward the trailing side, a first section to be pressed which is provided on the trailing-side side surface of side surfaces which form the recess of a brake padand which are raised outward in the radial direction of a rotor. Also, the pad spring has a second pressing section extending axially and provided to the base, the second pressing sectionpressing radially inward on the bottom surface of the recess of each of the pair of brake pads, the bottom surface being a second section to be pressed which is provided on an outer peripheral section.

A retraction spring comprising: (a) a body portion; (b) a first end; and (c) a second end, the second end connected to the first end via the body portion, wherein the retraction spring is configured to connect between mounting points of a caliper housing and attachment points along a bottom peripheral edge of one or more brake pad assemblies.

A brake pad is incorporated into a caliper so as to be movable in the axial direction of a rotor and rotatable around a rotation axis; a piston which presses the brake pad toward a disk rotor; and biasing members which bias the brake pad in order to hold the brake pad, wherein: the brake pad has contact sections, which are sections contacting the biasing members; the contacting sections have contact planes coinciding with virtual planes including the rotation axis of the brake pad; and the biasing members bias the contact planes in a direction perpendicular to the contact planes.
