Application device for a disk brake
An application device for a disk brake includes an application shaft extending transversely of an application axis, a first support for supporting the application shaft on an application element, which is shiftable in the direction of the application axis, and a second support for supporting the application shaft on an abutment. The first and second supports have arc-shaped support surfaces on the application shaft, wherein the directions of the curvature of the support surfaces are the same, but the imaginary centers thereof do not coincide. The first and/or the second support has a support element which can shift transversely of the application axis. The support element is a sliding element, which is supported with a second flat slide face on a first flat slide face provided on the abutment or on the application element.
