Flexible bearing or mounting with unidirectional damping for internal combustion engine has rubber spring giving three-dimensional flexibility and enclosing hydraulic fluid chamber

摘要

The flexible bearing (1) incorporates a piston and cylinder unit (9) acting as a unidirectional frictional damper. The piston rod is connected to a fastening bolt (10) and a cup-shaped metal housing (6) forming a space (11) surrounding the damper unit. A rigid metal plate (5) and a reinforced flexible membrane (4) form the floor of a space (7) filled with a fluid (8). A rubber spring (2) closes the top of the fluid space. The rubber spring has a cylindrical metal rim (2a) round its edge, attached to the cup-shaped metal housing and has a central fastening (3) consisting of a bolt (3b) connected to a frustoconical body (3a) vulcanized to the rubber spring.
