Disk brake including a brake caliper and an application device arranged therein for applying force to the brake pads of the disk brake, wherein a component of the application device is a brake lever which can be actuated by a force element and preferably by a pressure cylinder and is composed of a lever arm against which the force element is supported and an application shaft. The application shaft is supported, on one side, against a pressure piece operating in the direction of the brake pads and, on the other side, with the interposition of a shell, against a channel arranged on the inside of the brake caliper, wherein the curvature of the shell is complementary to the curvature of the channel. In order to develop the disk brake and the shell assembly by constructive measures so as to prevent the shell assembly from moving out of the original position even in the case of long-term use and under frequent load caused by braking, an opening of a bore is located in the channel.

Disk brake and shell assembly for pressure transmission in a brake application device of a disk brake

The invention proposes a disc brake having a brake caliper () and a tensioning device arranged therein for applying force to the brake linings of the disc brake, wherein part of the tensioning device is a brake lever () which can be actuated by a force element and preferably by a compressed air cylinder. The brake lever is composed of a lever arm (), against which the force element is supported, and a brake application shaft (), which is supported against a pressure piece () acting towards the brake linings, and is also supported from the inside against the brake caliper, wherein the brake caliper () and the brake application shaft () face each other and are formed as shells () in which a supporting roller () with a roller axis (A) running transverse to the tensioning direction (Z) is mounted. To keep the mutual movability of the parts involved low by the simplest measures possible and without the need for additional parts, the supporting roller () is supported with the lateral surface (A) thereof directly in one of the two shells () and is designed to be non-rotatable or have only limited rotational movement with respect to this shell. The supporting roller () also serves as a means to centre the brake lever () laterally in the brake caliper. A supporting roller particularly suited to these purposes is also to be created.

Disc brake with a tensioning device arranged therein and supporting roller for the tensioning device

A vehicle disk brake has a brake-application device providing a braking force and has a force element and a pressure-boosting lever arrangement. A readjustment device for compensatory readjustment of the wear-induced air clearance of the brake is provided that has a rotatably arranged drive element to be actuated by the brake-application device, a readjustment element arranged rotatably on the same axis, and a transmission device arranged in the movement path between drive element and readjustment element. To provide a readjustment device of a structurally simple design with a small number of parts, the transmission device is in the form of a helical wrap spring which is radially supported at the inner side along a first helix section relative to the drive element and is radially supported at the outer side along a second helix section relative to the readjustment element.

Vehicle disk brake

A disk brake is proposed for a vehicle, preferably a commercial vehicle, having a brake caliper, a brake application device, an adjusting device, a brake lever, and a mechanism which couples the brake lever to the drive element. The brake caliper engages over a brake disk and brake linings on both sides of the brake disk. The brake application device can be actuated by way of a force element, preferably a pneumatic force element. The adjusting device compensates for the brake lining and brake disk wear. The adjusting device is arranged on an adjusting axis which extends in the brake application direction, and is provided with a drive element which can be rotated about the adjusting axis.

A disk brake for a utility-vehicle wheel includes a brake caliper reaching around a brake disk, an application device arranged in the brake caliper on one side of the brake disk actuated by means of a force member, brake pads on both sides of the brake disk. At least the application-side brake pad is arranged in a pad duct having first and second supporting surfaces which have the same distance from a pad duct center line in the circumferential direction, and against which the brake pad lies, a brake lever which is part of the application device and is composed of a lever arm supporting the force member, and an application shaft connected to the lever arm and mounted inside the brake caliper on a pivot axis and resting in a rotationally movable manner against a pressure piece working against the application-side brake pad.

Disk brake for a utility-vehicle wheel

A braking device for wheels of vehicles such as trailers includes a caliper in which brake linings are guided. Between these linings, at least one brake disk is displaceably held on driving toothing of a wheel hub. A pneumatically operable mechanical adjusting device interacts with the brake linings. The braking device includes at least one brake disk in a caliper which is fixed. On one end, the caliper is connected by a fastening element with an axle element of the vehicle. On the caliper, an enclosing housing for bearing the adjusting device is held. By way of a bearing plate, the adjusting device is also supported on the caliper. Pressure pistons of the device are guided by a one-part yoke in a jointly axially adjustable manner and can be acted upon by pressure with respect to the brake linings and the brake disks.
