DESCRIZIONE
The invention relates to a clamping jaw for locking devices for components which are arranged in a rotatable and/or displaceable manner, the locking device having a brake rail (9), wherein either the brake rail (9) or the clamping jaw (12) is fixedly connected to the component which is arranged in a rotatable and/or displaceable manner. The clamping jaw (12) has a braking surface (13), which faces the brake rail (9) and has a braking profile that extends substantially transversely to the direction of movement of the component, is in operative connection with an actuator (11) and can be moved by the latter against the brake rail (9), whereby the braking profile exerts a locking effect on the surface of the brake rail (9). According to the invention, the braking profile that extends substantially transversely to the direction of movement of the component is composed of blades (14) that engage into the brake rail (9) or of a plurality of cylinder portions (23) which are arranged one behind the other in the direction of movement of the component and emerge in a bead-like manner from the braking surface (13), wherein the blades (14) or cylinder portions (23) are arranged in a V-shape on the braking surface (13) of the clamping jaw (12). The braking profile can also be arranged on the brake rail which in this case is made of a harder material than that of the braking surface of the clamping jaws.
