Linear brake operated by means of external energy

A linear brake for attachment on a slide that can be moved along a guide rail,

• with a brake housing which at least partly surrounds the guide rail,
• with a force store arranged in or on the brake housing,
• with a brake piston axially loaded by the force store, wherein axially protruding piston ends of said piston surround the guide rail in a fork-like manner,
• wherein the brake piston for braking/clamping purposes is movable at right angles to the direction of movement between the slide and the guide rail by way of the force store,
• wherein the piston ends of the brake piston are arranged on either side of the guide rail and exhibit opposing piston bevels which cooperate with wedge bevels which are provided on clamping jaws on either side of the guide rail, said clamping jaws being connected by a U-shaped transfer plate,
• wherein the clamping jaws, due to the pressing force of the force store onto the brake piston, are pressed against the guide rail,
• and wherein a piston space is disposed on the brake piston, which piston space by way of a connection bore is loaded with a pressure medium to work against the force of the force store and to affect a release of the linear brake,
• characterized in that
• the brake piston is configured as a cylindrical annular piston, which is loaded on one end face by the force store arranged centrally in the annular piston, and has on the other end face the piston ends with the bevel faces,
• and that the piston space is ring-shaped and is situated on the radial outside of the cylindrical ring piston in the region of the separation slot between the ring piston and the housing body,
• wherein the face side of the piston space is delimited by a piston ring attached radially outside the ring piston.
