Abstract
The invention relates to a stop element () for a hydraulic bearing and a hydraulic bushing equipped therewith. The proposed hydraulic stop element () with a stop body (') and a stop surface () is implemented as a piston-cylinder-assembly with an elastomeric bearing () with at least two work chambers for a fluidic damping means. The cylinder () of this piston-cylinder-assembly is inserted into the solid material surrounding the outer surface of a metallic element of the elastomeric support () which delimits the corresponding work chamber (′) of the elastomeric bearing () perpendicular to the main load direction (r). A piston (′) which forms the stop body with a stop surface () is movably guided in the cylinder () in the main load direction (r) of the elastomeric bearing. A buffer () is arranged on the bottom of the cylinder (), with at least one throttle channel () which is connected for flow-conduction with the work chamber (′) of the elastomeric bearing extending through the side wall.
