A damaged or missing engine undershield can also cause a drive belt to wear faster. An undershield protects the belt from dirt, sand and water. If the undershield is missing, water and small rocks can get under the belt and wear it faster.
Detailed features enhance aerodynamics and stability
Aerodynamic performance was enhanced by detailed development in all areas of the vehicle. To prevent unwanted drag, the front end was completely sealed using a hood seal and shielding beneath the engine, allowing air to be ducted efficiently via the grille to the cooling pack. Airflow beneath the car is managed by tailored panels on the underbody, with a lower front deflector and speed lip, engine undershield and front-wheel deflectors.
Röchling Automotive uses a multi-layered encapsulation process consisting of a thermoplastic sandwich for engine undershield systems. Low-weight reinforced thermoplastics (LWRT) are ideally suited as an insulation material for such applications due to their high enclosed air pore volume. However; low thermal conductivity is not the only outstanding material property; due to the open-pore form of the component surfaces, LWRT also features excellent sound absorption characteristics. This prevents disturbing noise emissions in the vehicle interior and its surroundings, contributing to a significant increase in comfort.
Röchling Automotive supports system design through early involvement in the development process for engine capsule systems. In combination with an active grille shutter, the pressure losses during air flow are significantly reduced in the process.
Röchling Automotive is among the leading manufacturers of engine undershields and underbody panels and offers the complete range of manufacturing processes from one source. Among the basic functions of these components are protection against rock chips and corrosion, and improved aerodynamics and acoustics. However, against the backdrop of more stringent regulations as well as higher demands for comfort, integrated acoustical functions are gaining significance. Röchling Automotive’s Softlofting™ technology enables the manufacturing of the lowest weight and highest acoustically efficient underbody panels and wheel arch liners; which have been the benchmark in the industry for several years.
A variety of development services for shielded underbodies, including aeroacoustic underbodies, lightweight underbodies, or modularly constructed underbodies, are performed in-house.
