Abstract

The invention relates to an overload protection device which has a force-loaded or torque-loaded component, a chamber for receiving a fluid which is at a predetermined pressure, and at least two transmitting elements which are connected to said component in a force-transmitting manner. The transmitting elements serve to transmit a counter-force or a counter-torque, which is generated by the pressure acting upon said transmitting elements, to the component, and is, at the same time, part of a sealing arrangement which occludes an outlet of the chamber due to the fluid pressure. If the force or torque acting upon the component are greater than the counter-force or counter-torque resulting from the predetermined pressure, the sealing arrangement unblocks the outlet, as a result of which the pressure in the chamber drops below said predetermined pressure.

Dependent claims

Overload protection device comprising:

a force-loaded and/or torque-loaded component, and
at least two transmitting elements, of which at least a first transmitting element responds to forces and/or torques in a different direction than at least a second transmitting element, each transmitting element having a chamber for receiving a fluid at a fluid pressure, and each transmitting element connected to said component in a force-transmitting manner, for transmitting a counter-force and/or counter-torque, which is generated by the fluid pressure acting upon the respective transmitting element, to the component,
wherein each transmitting element is part of a sealing arrangement which occludes an outlet of the respective chamber due to the fluid pressure and which unblocks said outlet if the force and/or torque acting upon the component is/are higher than the counter-force and/or counter-torque resulting from the predetermined pressure, as a result of which the pressure in the respective chamber drops below said predetermined pressure.
