Abstract

Es wird eine Kniehebel-Spannvorrichtung vorgeschlagen, die eine nach Art eines fluidbetätigten Arbeitszylinders ausgeführte Betätigungseinrichtung (1) aufweist. An der Betätigungseinrichtung (1) ist ein Lagerungskopf (2) vorgesehen, an dem ein Spannarm (3) verschwenkbar gelagert ist, der über einen Kniehebelmechanismus (12) mit einer Betätigungsstange (6) der Betätigungseinrichtung (1) in Wirkverbindung steht. Die Betätigungseinrichtung (1) ist mehrstufig aufgebaut und enthält wenigstens zwei axial hintereinandergeschaltete Betätigungseinheiten (13, 13'), die jeweils einen mit der Betätigungsstange (6) bewegungsgekoppelten fluidbeaufschlagbaren Betätigungskolben (14, 14') aufweisen.

Figure 00000001
A toggle lever tensioning device is proposed, which has an actuating device (1) designed in the manner of a fluid-operated working cylinder. A bearing head (2) is provided on the actuating device (1), on which a tension arm (3) is pivotably mounted and is operatively connected to an actuating rod (6) of the actuating device (1) via a toggle lever mechanism (12). The actuating device (1) is constructed in several stages and contains at least two actuating units (13, 13 ') connected axially one behind the other, each of which has an actuating piston (14, 14') which can be fluidly actuated to the actuating rod (6).
