Embodiment Construction

[0038] figure 1 A perspective outside view of an externally actuated linear brake (LBR) according to the invention is shown, comprising a brake housing (1) which partially encloses a guide rail (F), also shown. In order to deliver external energy in the form of compressed air or hydraulic oil, the linear brake (LBR) shown has a connection hole (A) in the brake housing (1) for connection to an external pressure medium source.

[0039] figure 2 A cross section of a linear brake (LBR) according to the invention is shown transverse to the direction of movement of the linear brake (LBR) on the guide rail (F). In all figures the brake piston (3) is shown in its upper end position. In this case, the piston ring (8) bears against the inner side of the housing cover (1.2) and the brake is released.

[0040] In the largely symmetrical brake housing (1), which is constructed in three parts and consists of the component housing base (1.1), housing cover (1.2) and housing bottom (1.3),...

Abstract

The invention relates to a linear brake (LBR) intended to be mounted on a slide movable along a guide rail (F), comprising a brake housing (1) at least partially surrounding the guide rail (F), comprising a brake An energy store on or in the housing (1) and comprising a brake piston (3) loaded by the energy store, fork-shaped surrounding the guide rail (F), said brake piston being transverse to the sliding The direction of motion of the movement between the block and the guide rail (F) is the guide rail. The brake piston here connects the two clamping jaws (7) to the U-shaped transfer plate (6) via the opposite piston ramps (3.2) and wedge ramps (5.1) arranged on both sides of the guide rail (F) Squeeze toward rail (F). The brake piston (3) is designed as a cylindrical ring piston, which is acted on one end side by an energy store (2) arranged centrally in the ring piston and which has a The piston end (3.6) with the inclined surface (3.2) and the piston space (3.5) are formed annularly and on the radially outer side of the cylindrical annular piston (3) between the annular piston and the housing base (1.1) In the region of the parting seam (1.4) between them, the piston ring (8) connected radially to the outside of the annular piston delimits the piston space (3.5) on the end side.

Description

technical field [0001] The invention relates to a linear brake disengaged by the delivery of external energy in the form of compressed air or hydraulic oil, intended to be mounted on a slide movable parallel to a guide rail. It is provided here that the housing of the linear brake at least partially surrounds the guide rail and that one or more actuator elements which interact with the energy store and are actuatable by feeding external energy are arranged in the housing of the linear brake. The brake element causes or cancels the clamping action of the linear brake on the guide rail. Background technique [0002] Brakes for commercially available guide rails are known from the prior art, as disclosed in DE 101 27 664 C1. It is stated here that with the fork-shaped armature pretensioned by means of a spring element, two wedge elements arranged laterally to the guide rail and opposite to each other press against the guide rail transversely to the direction of movement of the...
