Tenneco Scalable Suspension Architecture Provides Full Platform Solutions Regardless Of Powertrain

Company uses flexible actuator design to easily scale up semi-active suspension systems to advanced and fully-active systems on all models and powertrains within a single platform

Brussels, Belgium, June 22, 2016 –Tenneco announced today that its Scalable Suspension Architecture can provide car manufacturers with a highly differentiated range of vehicles within one single platform.

Tenneco’s Scalable Suspension concept leverages the power of the Monroe® Intelligent Suspension portfolio of semi-active and active suspension technologies to offer car manufacturers enhanced suspension systems using a flexible actuator design to easily scale up semi-active suspension systems to advanced and fully-active applications.   

 

“Scalable Suspension responds to the increasing need for differentiation as car manufacturers seek to offer a wide variety of different driving experiences on multiple car types within a single vehicle platform,”  said Rudi Schurmans, executive director global engineering, Tenneco Ride Performance. 

 

Scalable Suspension starts with the latest generation of Continuously Variable Semi-Active Suspension systems (CVSA2) which continuously adjust shock absorber damping levels to road conditions and vehicle dynamics like speed, turning, cornering and driver inputs. The system provides optimum driving safety and improves ride smoothness and NVH (noise, vibration and harshness), achieving the optimal balance between ride comfort and handling.  The continuously controlled damping works with the “skyhook” principle for body control, using additional algorithms for better road contact, steering and braking.

 

The CVSA2 system is controlled by a powerful electronic control unit (ECU) designed to exploit the full potential of the electro-hydraulic valve  system by processing input data sent from  sensors placed at key locations on the vehicle. Further input signals are provided from the in-car network.

 

The CVSA2 system uses control software that processes sensor information on  wheel motion, steering wheel angle, vehicle speed, brake pressure and other chassis control factors  and sends signals that independently adjust the damping level of each shock absorber. CVSA2 dampers allow a large separation between maximum and minimum damping levels and adjust instantaneously to ensure the optimum in ride comfort and firm, safe vehicle control.

 

Scalable Suspension offers the OEM a unique product differentiation strategy. Each combination of the three Scalable Suspension solutions can be efficiently engineered on a single OEM platform as the actuator designs share the same vehicle interfaces, several common components, production processes, sensors and ECU. By using CVSA2 as the standard premium suspension technology, the OEM can add Kinetic® roll control as an option for sports cars and/or SUVs and  propose ACOCAR® as the ultimate comfort and handling solution on luxury saloons or SUVs.

CVSA2/KINETIC® combines the CVSA2 technology with an interconnected hydraulic roll control system to significantly improve the comfort and handling performance of sports cars while also delivering superb on-road comfort, off-road traction and articulation performance on sports utility vehicles. In addition, the CVSA2/ KINETIC® solution is low in weight and energy consumption, helping to reduce CO2 emissions through reduced fuel consumption.

 

Using the Scalable Suspension concept, CVSA2/KINETIC® can easily be implemented as an option on platforms already equipped with CVSA2. The  anti-roll bars are replaced by hydraulic connections between the corners and the system can be extended with a variety of hydraulic ride height systems including discrete lifting, continuous leveling or hydro-pneumatic.

 

The fully-active ACOCAR® suspension system provides ultimate comfort as a result of its flying carpet-like control of body and wheel motion.  By independently supplying hydraulic pump flow to the corners, ACOCAR® is able to generate active force in addition to damping.

This replaces the anti-roll bars and keeps the car body flat at all times, while controlling wheel movements to improve tire to road contact. As a result, the ACOCAR® system allows independent control of roll, pitch and heave, providing superior handling and safety while optimizing comfort.

 

With Scalable Suspension, ACOCAR® can easily be implemented as an option on platforms already equipped with CVSA2 by replacing the anti-roll bars by electro-hydraulic power packs on each corner. As with CVSA2/KINETIC®, the system can be extended with a variety of hydraulic ride height systems including discrete lifting, continuous leveling or hydro-pneumatic.

About Tenneco - Aftermarket EMEA

About Tenneco   
Headquartered in Lake Forest, Illinois, Tenneco is one of the world’s leading designers, manufacturers and marketers of Ride Performance and Clean Air products and technology solutions for diversified markets, including light vehicle, commercial truck, off-highway equipment and the aftermarket, with 2017 revenues of $9.3 billion and approximately 32,000 employees worldwide.  
 
On October 1, 2018, Tenneco completed the acquisition of Federal-Mogul, a leading global supplier to original equipment manufacturers and the aftermarket with nearly 55,000 employees globally and 2017 revenues of $7.8 billion.  Additionally, the company expects to separate its businesses to form two new, independent companies, an Aftermarket and Ride Performance company as well as a new Powertrain Technology company, in late 2019.

About the Future Aftermarket and Ride Performance Company
Following the separation, the aftermarket and ride performance company will be one of the largest global multi-line, multi-brand aftermarket companies, and one of the largest global OE ride performance and braking companies.  The aftermarket and ride performance company’s principal product brands will feature Monroe®, Walker®, Clevite®Elastomers, MOOG®, Fel-Pro®, Wagner®, Champion® and others. The Aftermarket and Ride Performance company would have 2017 pro-forma revenues of $6.4 billion, with 57% of those revenues from aftermarket and 43% from original equipment customers. 
 
About the Future Powertrain Technology Company
Following the separation, the powertrain technology company will be one of the world’s largest pure-play powertrain companies serving OE markets worldwide with engineered solutions addressing fuel economy, power output, and criteria pollution requirements for gasoline, diesel and electrified powertrains. The powertrain technology company would have 2017 pro-forma revenues of $10.7 billion, serving light vehicle, commercial truck, off-highway and industrial markets.
