Hydraulically damped flexible bearing for road vehicle internal combustion engine has narrow damping channel in piston moved up and down by magnetic coils connected to control module
Hydraulically damped flexible bearing for road vehicle internal combustion engine has narrow damping channel in piston moved up and down by magnetic coils connected to control module
The bearing (10) has a conical spring (30) made e.g. of rubber, enclosing a working chamber (12) filled with a hydraulic fluid. The fluid can flow through a damping channel (16) in a movable piston (20). The edges of its flat end surfaces (33) are connected to an intermediate housing (15) by flexures (17). The intermediate housing holds a magnetic yoke (23) with magnetic coils (22) and permanent magnets (21). The magnetic coils are connected to a control circuit (25) and are used to move the piston up and down.
