Embodiment Construction
[0041] The embodiment of a clamping and / or braking device 1 shown in schematic longitudinal section in FIG. 1 has an annular housing 3 comprising a first part 5 and a second part 9 with an annular groove 7, The latter is connected to the first part 5 by screwing, for example. An annular plate-shaped element 11 is arranged in the recess 7 between the first and the second housing part 5 , 9 . The annular plate-shaped element 11 is slightly convex in radial section and acts with its outer end or its outer edge 11a on the circumferential wall of the annular groove 7 of the first housing part 5 .
[0042] as by Figure 1b It is obvious that the annular plate-shaped element 11 , for example made of a thin steel sheet, is connected on one side to a sealing element 13 , for example a relatively hard but still sufficiently flexible rubber ring. Such as Figure 2a and 2b As shown in , the annular plate-like element 11 is provided with a plurality of slits 14 which extend radially in...

The invention relates to a clamping and / or braking device, comprising a housing (3), in which at least one discoid element (11) is housed, with a first end (11a) supported on the housing and which transmits clamping or braking forces to an object (17) or an operating element (21) with a second end (11b). The discoid element has a convex flexing region, at least in the starting position thereof, embodied to be resistant to pressure and yet elastically flexible such as to form a spring element between the housing and an operating end of the discoid element, whereby an essentially sealed pressure chamber (15) is formed between the convex side of the discoid element and the housing, which may be pressurised and the discoid element is embodied such that, on pressurising the pressure chamber, a movement of the second end of the operating element in the direction of the object occurs as a result of the reduction in the curvature of the flexing region, or an increase in the clamping and / or braking force transmitted is achieved.
Description
technical field [0001] The invention relates to a clamping and / or braking device having the features of the preamble of claim 1 . Background technique [0002] Clamping or braking devices are known in a wide variety of embodiments for very different applications. For example, from EP-A-0 936 366 a braking device for linear guides is known, which has a support movable along a guide rail. The support has a plurality of brake pads which act on two longitudinal sides. The support is H-shaped and has a thin, elastically bendable web and two lower sides, with which the guide rail engages around the support. A brake block is arranged between each lower side and the guide rail. The support is provided with two upper sides, which together with the webs form a receiving space, in which a force-generating device acting on the upper sides is arranged. This can be a hydraulically or pneumatically actuatable crank lever system or a piezoelectric actuator. In addition, a hydraulically...
