Other Products and Services

Delphi is well known around the world for providing a wide range of vehicle innovations. As a manufacturer of components, modules, and systems for each segment of the vehicle, Delphi specializes in tailoring products to support each customer’s specific requirements. For example, with expertise in the areas of suspension, brakes, and steering, Delphi can simply provide a suspension system or integrate ride dynamics technologies to create a complete chassis system.

Delphi’s expertise extends to the design and manufacture of a complete line of powertrain and suspension mounts, including adaptive hydraulic mount systems, to meet a range of automotive requirements. Numerous technical centers and manufacturing sites located from North America to China help Delphi provide personalized customer service and timely delivery of products.

Description

By using magneto-rheological (MR) fluid in the Delphi MR powertrain mount, the damping and dynamic stiffness properties of the mount can be instantaneously controlled during a variety of road inputs, including uneven surfaces, potholes, and bumps. The MR mount also helps control the engine’s torque transient response to the engagement and shifting of gears. The MR powertrain mount system comprises the appropriate MR mount(s), a sensor or sensor set, a system controller (electronic control unit), and the associated wiring.

Typical Applications

The MR powertrain mount is applicable to front- and rear-wheel-drive engine configurations. The controllable MR mount can be applied as a load-bearing mount to help control vertical motion of the powertrain, or as a torque-reaction mount to help control motion due to torque transients. Ideally, it would be applied as a combination of both. The MR mount is appropriate for passenger cars, SUVs, and light- and medium-duty trucks.

Performance Advantages

The MR powertrain mount uses magneto-rheological fluid instantaneous-change-in-state technology. This helps enable real-time control of the mount dynamic properties, which allows the mount to adapt to road and powertrain motion inputs. As a result, the driver and passengers experience less noise, bounce, and vibration from the powertrain and suspension systems.

Availability

The MR powertrain mount is scheduled to be available for the 2007 model year.
