Embodiment Construction

[0028] figure 1 and figure 2 Shown is a disc brake 100 for a rail vehicle, in particular a laterally movable wheel set, comprising an eccentrically driven brake caliper 7 with two caliper rods 6, 8 at one end thereof It is coupled to each brake shoe 15 and, in its central region, to a braking force motor 14 . The brake disk 1 is only partially shown as a shaft disk.

[0029] In a coupling point 10 which can be regarded as spatially fixed, the caliper lever 6 of a brake caliper 7 is rotatably coupled to the brake housing 2 about an axis of rotation. The caliper lever 8 on the other side is rotatably coupled to the brake housing 2 in a coupling point 10 by means of a pin 9 , which is rotatably supported here about an axis of rotation parallel to the axis of rotation of the caliper lever 6 . On the brake housing 2 and mounted eccentrically, axis-parallel pin projections 11 , on which the caliper lever 8 is supported.

[0030]Stretch out a pivot arm 2 from pin 9, the piston r...

Abstract

A disk brake of a rail vehicle, having a brake caliper, the caliper arms of which are coupled with one end to brake shoes and with the other end to a wear adjuster, the length of the wear adjuster is adjustable by a control mechanism depending on the stroke of a brake force motor. A control rod of the control mechanism acts upon an adjusting element of the wear adjuster, the adjusting element includes a freewheeling mechanism mounted in a housing of the wear adjuster and a stop section of the adjusting element loaded in a self-adjusting starting position against a stop of the housing by at least one return spring element. The stop contains at least one element that is elastic in the direction of abutment.

Description

technical field [0001] The invention relates to a disc brake for a rail vehicle. Background technique [0002] In compact brake caliper units for rail vehicles, the wear of brake linings and brake discs is automatically compensated by lengthening or shortening the pressure rod or tie rod adjuster. The lengthening or shortening of the adjuster takes place by means of a screw drive as a nut-screw system. In order to achieve the greatest possible adjustment per actuation, the thread construction has a very large lead. The thread is therefore not self-locking. One of the threaded drive elements, such as a nut, is held in a rotationally fixed manner, while the other threaded drive element, such as a spindle, is rotatably mounted. By means of the control mechanism, the adjusting rod is rotated by means of a freewheel (for example a sleeve-type freewheel), which in turn rotates the spindle or the nut of the plunger adjuster such that the adjuster is extended, for example. When ...
