Abstract
A frictional damper includes a housing having a longitudinal axis, a tappet which is movable along the longitudinal axis, a frictional unit for generating a direction-dependent frictional force on the tappet, wherein the frictional unit includes at least one friction lining lying rubbingly against the tappet, and a switching unit for variably setting the frictional force.
Claims25
A frictional damper comprising:
- a. a housing having a longitudinal axis,
- b. a tappet which is movable along the longitudinal axis,
- c. a frictional unit for generating a direction-dependent frictional force on the tappet, wherein the frictional unit comprises at least one friction lining lying rubbingly against the tappet,
- d. a switching unit for variably setting a magnitude of the frictional force;
- wherein the switching unit has a switchable actuator and a locking element which is coupled mechanically to the actuator;
- e. a failsafe unit for a failsafe function of the frictional damper for arranging the locking element in a locked arrangement on the friction lining carrier in such a manner that a maximal direction-independent frictional force is in effect.
