The present invention relates to a high-speed controlling device, suitable for displacing a switching element between two positions with very short switching times. Said device comprises two switchable electromagnets, between which an armature, with a driven coupling to the switching element, is arranged. According to the invention, said armature contacts the first electromagnet in the first position of the switching element and contacts the other electromagnet in the second position of the switching element. In order to obtain particularly short switching times for the switching element, the armature can be firmly secured to a shaft, which is rotatably mounted about its longitudinal axis and to which said switching element is also fixed in an axially offset manner in relation to the armature.

The invention relates to a disk brake which comprises a brake disk (4), having a preferred running direction (D), a first bake shoe (2), having a first center of gravity (S1) on a first side of the brake disk, a second brake shoe (3), having a second center of gravity (S2) on a second side of the brake disk, and a caliper (1) for transmitting the braking forces produced by the second brake shoe to the first side of the brake disk. A first caliper arm (1.1) is located on the first side of the brake disk, and a second caliper arm (1.2) on the second side of the brake disk. A brake application device (5) has a central axis (N) which is perpendicular to the brake disk and is adapted to force the first brake shoe against the brake disk. The second center of gravity, both in the position of rest and when the brake is actuated, is off-set by a predetermined first path (V) in the direction of a brake disk run-out side corresponding to the preferred running direction of the brake disk. The two caliper arms are off-set from each other by a predetermined second path (W) in the direction of the brake disk run-out side. According to the invention, a linking device (1.3, 1.4) interlinking the caliper arms is located radially closer to the brake disk on the brake disk run-out side than on the run-in side.

The invention relates to a disc brake, in particular for commercial vehicles, comprising a brake disc (2), a brake caliper (1), a pneumatically acting operating cylinder (3) which has an operating device (8), an applying device (5) which has a rotating lever (7) and a camshaft (6) running parallel to a brake disc plane (6) and at least one brake lining (4). On activating the operating cylinder, the operating device presses the brake lining against the brake disc by means of the rotating lever and the camshaft. According to the invention, a frictional damping device (13, 20) is provided outside the force path of application, which influences the resonant behaviour of the brake.

A disk brake includes a brake disk with a preferred rotational direction, with a first brake pad with a first center of gravity on a first side of the brake disk, a second brake pad with a second center of gravity on a second side of the brake disk, and a caliper for transmitting the braking forces produced by the second brake pad to the first side of the brake disk. The second center of gravity is offset from the first center of gravity by a predetermined distance in the direction toward the side of the brake disk that trails when the disk is rotating in its preferred direction.
