A moving device includes an elastic tube, a sectional shape of which is elastically deformable according to an internal pressure given by fluid, a slider unit capable of moving forward and backward in a longitudinal direction of the elastic tube according to a change in the sectional shape of the elastic tube, a brake provided in the slider unit and configured to be deformed in a direction perpendicular to the longitudinal direction of the elastic tube to be capable of coming into sliding contact with a target object, and a fluid adjusting section configured to supply air to or discharge air from the elastic tube respectively via first and second fluid supply pipes that respectively communicate with insides on a distal end side and a proximal end side of the elastic tube.

A disc brake for a commercial vehicle has a brake caliper spanning a brake disc on the vehicle side, in which brake caliper a clamping device is arranged which has a pivotable brake lever engaging in at least one bridge carrying a brake plunger, which at the same time is directly or indirectly supported at the inner side of a wall of the brake caliper. The contact area of the bridge at the brake lever or of the brake lever at the brake caliper is configured as a pivot bearing having a bearing shell cross-sectionally configured as an arc forming a part of the pivot bearing. The bearing shell is placed in a seating. The disc brake is configured such that the bearing shell is located in the pivoting direction of the brake lever with its opposite longitudinal borders at stop edges, which longitudinally limit the trough-shaped seating.

A braking device for a vehicle may have a disc with a disc body with at least one connection portion. The connection portion having at least one arm, which projects cantilevered. The arm has a free terminal end and an attachment root. The root has at least one contact area of an elastic element with seat walls. The at least one arm has at least one working portion which touches the engagement portion of a bush and affects the bush to abut against a dragging surface.

The invention relates to a braking and/or clamping device for a shaft guided in relation to a main body, comprising an actuation assembly and a shaft-coupling assembly. In this case, the actuation assembly comprises a split housing which has two bending plates which are elastically deformable in some regions. The bending plates each have tong jaws with friction surfaces, the respective surface normal of which are directed inwards. A sealed pressure chamber, which can be filled with a pressure medium, lies between the bending plates. Parts of a shaft-coupling assembly project between the clamping zones, said parts establishing the linking for the braked or clamped shaft. When the pressure in the pressure chamber is relieved, the frictional surfaces of the actuation assembly can be applied to the frictional surfaces of the shaft-coupling assembly, thereby producing the braking and/or clamping force. According to the present invention, a braking and/or clamping device is developed, which has a reduced structural width even with a large diameter, consists of few components and also functions in a simple, secure and maintenance-free manner.
