Abstract

Ein hydraulischer oder mechanischer Kraftverstärker mit kraftschlüssiger oder formschlüssiger Abstützung des Widerlagers wird auf der Vorderseite eines Pneumatikkolbens (2) angeordnet und mitbewegt. Ein reibungsarmer Druckschalter ermöglicht präzise Auslösung der Kraftverstärkung und verhindert Druckverluste durch Abbau der Vorspannung. Bei einem mechanischen Kraftverstärker ermöglicht die rechtwinkelige Lage der Mittellinien von Keilspalt und Druckkeil reines Wälzen der Rollen (14) im Hauptkraftfluß. Ein Druck-Doppelkegel mit gekrümmtem Übergang ermöglicht sanften Kraftanstieg und optimale Werte für Hub und Ausgangskraft, bei entsprechender Gestaltung auch Verriegelung des Ausgangsgliedes.

Figure 00000001
A hydraulic or mechanical force booster with non-positive or positive support of the abutment is arranged on the front of a pneumatic piston (2) and moved. A low-friction pressure switch enables precise activation of the power boost and prevents pressure losses by reducing the preload. In the case of a mechanical power amplifier, the right-angled position of the center lines of the wedge gap and pressure wedge enables the rollers (14) to be rolled in the main power flow. A pressure double cone with a curved transition enables a gentle increase in force and optimum values for stroke and output force, and with the appropriate design also locking of the output element.
