Abstract
A device for actuating a brake shoe of a brake, in particular a disk brake, includes a pivotably mountable lever element, and a transmission element configured to be mounted in a longitudinally movable fashion is such that a pivot movement of the lever element is translated into a longitudinal movement of the transmission element wherein a hydraulic chamber configured to be filled with a hydraulic fluid is arranged between the brake shoe and the transmission element for the transmission of force between the brake shoe and the transmission element.

A truck brake shoe actuation device of a brake, comprising:
- a pivotably mountable lever element;
- an actuator configured to actuate the lever element;
- a transmission element configured to be longitudinally movable and such that a pivot movement of the lever element is translated into a longitudinal movement of the transmission element;
- wherein a hydraulic chamber configured to be filled with a hydraulic fluid is located at least partially directly between a brake shoe and the transmission element for the transmission of force between the brake shoe and the transmission element;
- wherein the transmission element comprises a bearing shell which at least partially receives the lever element;
- and
- wherein the transmission element is located on an opposite side of the lever element from the actuator;
- a base body;
- a cylinder element mounted movably relative to the base body, wherein the base body and the cylinder element cooperate to form the hydraulic chamber, and wherein the cylinder element includes multiple pieces;
- and
- a sealing element arranged between the base body and the cylinder element, wherein the sealing arrangement is arranged within a rebate extending around an inside of the base body, and wherein a circumferential wall of the base body has an inclined surface.
A method for production or upgrading of a truck brake, comprising:
- providing a hydraulic chamber filled with hydraulic fluid between a lever element and a brake shoe;
- providing an actuator configured to actuate the lever element;
- providing a transmission element that is configured to be mounted in a longitudinally movable fashion and such that a pivot movement of the lever element is translated into a longitudinal movement of the transmission element, wherein the transmission element comprises a bearing shell which at least partially receives the lever element;
- and
- wherein the transmission element is located on an opposite side of the lever element from the actuator;
- providing a base body;
- providing a cylinder element mounted movably relative to the base body, wherein the base body and the cylinder element cooperate to form the hydraulic chamber, and wherein the cylinder element includes multiple pieces;
- and
- providing a sealing arrangement arranged between the base body and the cylinder element, wherein the sealing arrangement is arranged within a rebate extending around an inside of the base body, and wherein a circumferential wall of the base body has an inclined surface.
