Engine mounts having tuning capabilities and engine decking anti-rotational features

摘要

engine mounts for supporting and isolating an engine from a vehicle chassis are described, The engine mounts generally comprise four main components; an outer housing, at least one outer plastics insert, an interchangeable double v-shaped inner member, and an elastomeric portion. The elastomeric portion may comprise four double chevron elastomeric pads, or it may comprise a single web of elastomeric material having a plurality of legs extending therefrom. The out plastics inserts, the inner member, and the elastomeric portion are generally assembled together to form an inner assembly, which may then be pre-compressed and inserted into the outer housing to form an engine mount. These engine mounts may be easily modified, by changing the inner member, the plastics inserts or the elastomeric portion, so as to provide easy stiffness tuning capability to the engine mount. Additionally, these engine mounts may include anti-tilting, anti-rotating features that help reduce the amount of cocking or rotating of the inner member during engine decking.
