    摘要: A hydroelastic support, such as for use as an engine mount in a vehicle, comprises a liquid-filled working chamber (16) and a liquid-filled compensation chamber (18). The working chamber has a flexible-walled part which is flexed by the engine vibrations so as to create pressure changes within the working chamber. A control member (26) comprises a disc-shaped flexible rubber element (28) located within an aperture (27) in a rigid wall between the two chambers (16,18). The flexible element (28) flexes in response to the pressure changes in the working chamber and causes partial damping thereof. Upper and lower movement-limitation members (32,34), made of relatively rigid material, limit the flexing of the flexible element (28) in response to high amplitude vibrations.

    摘要: An engine mount for a vehicle has a first rigid fixture (12) for attachment to the engine and a second rigid fixture (13) for attachment to the chassis or body, an armature (14) attached to the second rigid fixture (13), and a resilient rubber support (10) between the first fixture (12) and the armature (14) for flexing in response to engine vibrations. The rubber support (10) defines a working chamber (22) containing hydraulic fluid which is in communication with a compensation chamber (37) via a helical conduit (38), so that engine vibrations are at least partially damped by oscillation of fluid in the conduit (38) between the two chambers (22,37). Two apertured grills (24,52) define a valve chamber (51) in which a flexible disc valve (46) is oscillatable. The lower grill (52) is rotatable by means of a control rod extending externally of the engine mount. It carries inclined ramps (72) cooperating with similar ramps on a lower plate (55) so that rotation of the lower grill (52) alters the free play of the disc valve (46). In this way, therefore, the flap valve (46) can be controllably rendered operative over a wide range of vibration amplitudes so as (for example) to reduce the dynamic stiffness of the engine mount during engine idling. Other means of adjusting the operation of the flap valve are described.

    摘要: A fluid-filled limiter for damping and limiting relative vibrations between the engine of a vehicle and the body of a vehicle, comprising a rigid base (12) for connection to one of the vehicle body and the engine, a resilient body (10) fixed to the base (12) and arranged in use, for periodic impacting with the other of the engine and the body and arranged resiliently to flex in response to such impacting, a flexible-walled chamber (14) being defined between the base (12) and the resilient body (10) and being filled with hydraulic fluid, the chamber being relatively incompressible in a direction towards the base (12) whereby the stiffness of the limiter is greater in a direction towards the base (12) than in a shear direction along the interface between the base (12) and the resilient body (10). The base (12) may encircle the body (10) and an inner armature (34) may be mounted generally concentrically in the base (12).

    摘要: An electromagnetic arrangement comprises an armature (12) mounted within a housing (5) and carrying an electrically energisable coil (14). A core (8) slides inwardly of a hollow space (10) against a compression spring (18) in response to electrical energisation of the coil (14), and slides in the opposite direction upon de-energisation of the coil in response to the stored energy of the spring (18). The core (8) is connected to an output member (6) by means of a control rod (24) freely slidable through the core (8) and which has an enlarged head (27) against which a second coil spring (28) acts. During inward movement of the core (8) in response to energisation of the coil (14), the core (8) pulls the output member (6) through the intermediary of a second spring (28) and a control rod (24) which is slidable through the core (8) and is fixed to the output member (6). During outward movement of the core (8) in response to de-energisation of the coil (14), an end face (15) of the core (8) pushes on an end face (26) of the output member (6). When the core (8) is at its innermost position, a predetermined amount of play (32) exists between the end (15) of the core (8) and the end face (26) of the output member (6). This allows the core (8) to accelerate before it abuts against the end face (26) of the output member (6).

    摘要: An engine mount for a vehicle has a first rigid fixture (12) for attachment to the engine and a second rigid fixture (13) for attachment to the chassis or body, an armature (14) attached to the second rigid fixture (13), and a resilient rubber support (10) between the first fixture (12) and the armature (14) for flexing in response to engine vibrations. The rubber support (10) defines a working chamber (22) containing hydraulic fluid which is in communication with a compensation chamber (37) via a helical conduit (38), so that engine vibrations are at least partially damped by oscillation of fluid in the conduit (38) between the two chambers (22,37). Two apertured grills (24,52) define a valve chamber (51) in which a flexible disc valve (46) is oscillatable. The lower grill (52) is rotatable by means of a control rod extending externally of the engine mount. It carries inclined ramps (72) cooperating with similar ramps on a lower plate (55) so that rotation of the lower grill (52) alters the free play of the disc valve (46). In this way, therefore, the flap valve (46) can be controllably rendered operative over a wide range of vibration amplitudes so as (for example) to reduce the dynamic stiffness of the engine mount during engine idling. Other means of adjusting the operation of the flap valve are described.
