Engine mounting with hydraulic damper has working chamber bounded by volumetrically stiff rolling bellows between separating plate and a roll-off piston

摘要

The mounting (2) has a spring component with at least one elastomer part acting a supporting spring (8) mounted on a supporting core inside the mounting housing and supported on the inside of the housing and a damper component (12) integrated into the engine mounting and acting independently of the volumetric flexibility of the elastomer part that is divided into a variable volume working chamber and a compensation chamber (22) by a separating plate (18). The working chamber is bounded by a volumetrically stiff rolling bellows (14) between the separating plate and a roll-off piston (16).
