Engine mounting with hollow cylindrical support spring

摘要

The mounting comprises an impact plate (18) which is fixed and sealed on the inner wall of a cup-shaped housing (7). An elastically attached control plate (25) rests against the housing so as to close and open an opening (19) in the impact plate. The rim of the control plate has an elastomeric ring (26) clamped between the impact plate and the housing. The control plate can be pneumatically or hydraulically controlled. The housing has an opening (30) for the control medium. An elastic wall (10) which separates the hollow interior into upper and lower chambers has a middle, thicker section (12) fixed to a bolt (11). There is at least one axial overflow opening (14) and a flexible outward-curving wall in the radially outer part (13).
