Patent ID: 7703753

Claim:
A stop element ( 1 ) comprising a stop body ( 2 , 2 ′), the stop element ( 1 ) being arranged in an elastomeric bearing ( 12 ) with an elastomeric bearing body ( 14 ) in a work chamber ( 16 , 16 ′) configured to receive a fluidic damping means and forming a limit stop, the limit stop limiting deformation of the bearing body ( 14 ) in a main load direction (r) by impacting on a surface area of an element of the elastomeric bearing ( 12 ) facing the stop body ( 2 , 2 ′), wherein the impact of the respective surface area on the stop body ( 2 , 2 ′) is hydraulically damped by the stop element ( 1 ), wherein the stop element ( 1 ) is configured as a piston-cylinder-assembly, comprising a cylinder ( 4 ) formed by a metallic sleeve, with the cylinder ( 4 ) being inserted in the solid material, which surrounds the outer surface of the cylinder ( 4 ), of a metallic element of the elastomeric bearing ( 12 ), which delimits the work chamber ( 16 , 16 ′) of the elastomeric bearing ( 12 ) perpendicular to the main load direction (r) and is provided with a corresponding opening ( 18 ), an elastomeric buffer ( 5 ) disposed at the bottom of the cylinder ( 4 ), at least one throttle channel ( 6 ) extending through the side wall of the cylinder ( 4 ) and connected for flow conduction with the work chamber ( 16 , 16 ′) of the elastomeric bearing, a piston ( 2 , 2 ′) which forms the stop body with a stop surface ( 3 ) and is movable inside the cylinder ( 4 ) in the main load direction (r) and is made of metal at least at its contact surfaces facing the cylinder ( 4 ), wherein in the unloaded state of the stop element ( 1 ), a cylinder chamber ( 8 ) is formed between the bottom ( 7 ) of the cylinder ( 4 ) and the piston ( 2 , 2 ′), which is filled with the fluidic damping means of the work chamber ( 16 , 16 ′) of the elastomeric bearing ( 12 ), the piston ( 2 , 2 ′) forming the stop body moves, when the stop element ( 1 ) is loaded, towards the cylinder bottom ( 7 ), thereby displacing damping means from the diminishing cylinder chamber ( 8 ) via the at least one throttle channel ( 6 ) into the work chamber of the elastomeric bearing.
