Switchable Restrictor

Designed for premium ride comfort, our mounts filtration solution integrates dedicated hydraulic configurations engineered to exhibit at least two distinct dynamic behaviors. This multifunctional response enables the product to adapt to varying operational conditions, effectively minimizing powertrain and road-induced vibrations. With flexible material options including natural rubber formulations, metals, and plastics, it ensures superior NVH performance, long-term durability, and cost-optimized integration across all mobility platforms.

Characteristics

Structures

Function: This fluid-filled elastomeric product is built by a Main Rubber Element (MRE) made primarily of natural rubber for its deformability properties, bonded to at least two components being metallic or composite. A glycol-type liquid is encapsulated between the MRE and an outer component. Its structure is designed to obtain at least two different states under the same excitation. The first state delivers a high level of damping at a specific frequency, and the second provides low dynamic stiffness at higher frequencies. This product handles engine torque and rotational motion while ensuring optimal filtration levels. Tailor-made design, from cradle to grave.
