SECURITY SYSTEM FOR DRIVE TECHNOLOGY CONSTRUCTION ELEMENTS

摘要

a security system for antriebstechnische construction elements, in particular brake (20) and soluble joints, with a hydraulically driven piston (21) of a cylinder (22) gliding is stored, with the piston (21) and the cylinder (22) each have a first surface (25) and second, by a wellenabsatz (35,36) of the first sliding surface (25) beabstandete sliding surface (26) which, with a space (24) axially between the wellenabsatz (35) of the piston (21) and the wellenabsatz (36) of the cylinder (22))with the working area (24) on one side in the area of the first sliding surfaces (25) of a first of a long term stable sealing system (27) and the other side in the area of the second sliding surfaces (26) with a second of a long term stable sealing system (28) is sealed, and at least one of the sealing systems, both a primary you telement as a secondary dichtelement contains.
