Shock absorber and anti-vibration mounting for engine - combines coil spring with wire braid core, and elastomeric pads to absorb larger shocks

摘要

A shock absorber and anti-vibration mounting for engines is provided with a base plate (1) which is fixed to the chassis of the vehicle. Two elastomeric pads (4) are bonded to the base (1) and slope towards each other to support a collar (7). The collar (7) carries a cylindrical mass of braid (9) surrounded by a compression spring (10). The upper end of the spring (10) fits in a housing (11) attached to the engine mounting plate (16). Normal engine vibrations are absorbed by deflections of the spring (10) and braid (9). High shocks are absorbed by deflection of the elastomeric pads (4). The use of knitted wire (9) and spring (10) provides a means of vibration isolation which is not affected by temperature variations.
