Abstract (en)

[origin: GB2333822A] A hydroelastic engine mount comprises a metal armature (10) which in use is bolted to the vehicle chassis. A hollow conically shaped damping member made of resilient elastomeric material (22) is moulded onto the armature (10) and supports a rigid metal fixture (26) which is bolted to the engine. A working chamber (24) is filled with hydraulic fluid and connected to a compensation chamber (40) by means of a conduit (42). Engine vibrations are partly damped by the resilient damping member (22) and also by the damping effect applied by the conduit (42) to the fluid passing oscillatingly through it between the two chambers (24,40). The conduit (42) is integrally formed in the armature (10). The armature (10) also includes an integral extension (13) which supports abutments made of elastomeric material (e.g. 44,56,58) which act against the surfaces (60,62) of the engine to limit its maximum movement. The damping material can be moulded onto the armature (10) at the same time as the resilient damping material (22) but can be of a different type.
