Fuel consumption and CO2 emission reduction are important to all new car designs and these can be directly impacted by reducing the weight of a vehicle. Tenneco’s lightweight technology provides a means to this goal and focuses on two key areas – size reduction and material substitution.
Lightweight technology for passenger cars and light commercial vehicles
Size reduction has been possible through use of adapted valve systems, optimized internal components and new tube forming techniques that provide structural integrity without cost penalty.
Lightweight technology uses new material such as plastic spring seat, hollow rod, aluminum, tube with variable wall thickness and composite material. For strut applications normal steel has been replaced by high strength steel with plastics used for add-on and modular components. These changes have achieved up to 30% weight reductions within market defined cost targets and without sacrificing strength, resistance or functionality.
Tenneco has developed concepts and expertise in some of the technological challenges to achieve these innovative developments, making advances in surface treatments, tube forming and material joining processes.
Lightweight technology for motorbikes
For forks, the focus is on aluminium stanchion tube, aluminium and carbon fiber outer tube, magnesium top cup and drop out, bladder sealed cartridge (patented) as well as titanium springs.
For shocks, the focus is on magnesium components, carbon fibre reservoir, titanium spring, double compression adjustment, high and low speed, rebound adjustment, total length adjustable and hydraulic spring pre-load adjustment.
