| 摘要 |
<p>The invention relates to a two-chamber support bearing with hydraulic damping, notably for the engine mounting of motor vehicles, which comprises at least one fluid-filled working chamber (1) and at least one compensation chamber (2) which is linked to the working chamber by way of a jet channel (8) whose cross-section can be modified by means of a first motorized actuator (20). The working chamber is provided with a buckling spring (14) which is integrated into one of its sides and whose stiffness can be modified by means of a second motorized actuator (21) which is independent of the first motorized actuator. The structural design provided for in the invention makes it possible for the two-chamber support bearing to be continuously adjusted to the damping of both low-frequency high-amplitude oscillations and high-frequency low-amplitude oscillations while said support bearing is in operation. Other advantages of the invention include its especially compact and economical structure.</p> |
