The high innovative strength of medium-sized German companies in the automotive supplier industry is helping to open up new possibilities. OEMs are increasingly outsourcing development work within the context of new topics such as E-mobility, autonomous driving or the use of weight-optimised carbon, aluminium or magnesium components. This trend is proving particularly beneficial to specialised supplier companies, which are managing to establish themselves as strategic partners to automotive manufacturers thanks to their flexibility and customer-specific innovation processes.
The speed of technological advancements will no doubt increase even further over the years to come, which will be accompanied by even shorter model cycles. This will in turn increase the requirements placed on supplier companies.
This will also be accompanied by innovation and price pressure, which is higher in the automotive supplier sector than almost any other industry. The inverse conclusion of this is that benefits and risks are very closely connected. For supplier companies, these challenges mean that a watchful eye and even closer communication with their OEM customers are required in order to respond quickly to unplanned scenarios.
High levels of competitive pressure, new technical requirements and the desire of automotive manufacturers to differentiate their performance from that of other companies all mean that components are now increasingly being developed to be customer and product-specific. Although seals and slide bearings are usually immediately available as standard products, this is not of particular relevance in the automotive industry with its specially developed model series. The benefit of noticeably longer service lives, for example, is increasingly leading to the use of customised solutions. ttv is addressing this trend with a dedicated development department.
Over recent years, ttv has further established itself as a specialist in the automotive sector, with its two competence fields of seals and slide bearings. Typical challenges faced by ttv in this area include applications on ventilation systems designed to improve the haptic qualities, or O-rings for drive units for cargo-loading systems, as seen in the aerospace industry.
The frequently installed standard stock products are no longer adequate to deal with the increasingly demanding requirements.
This development lead ttv to the strategic decision to set up a separate department for customer-specific product solutions, with first-class capacity to support ttv customers. ttv has an experienced team of technology and engineering specialists to help with this task, and we attend to every conceivable detail of a project. Material properties, material composition and design open up numerous possibilities for improving performance, and help keep influencing factors strictly on the outside.
Seals and slide bearings are only comparatively small components in the area of technological components and assemblies, but does not change the fact that both product categories are often crucial for the quality of functional components.
Customer and project-specific solutions from ttv have lead to demonstrable and significant increases in quality and haptic properties over recent years, combined with maximum service lives.
The contract came with a very clear brief. The ventilation system of a vehicle in the medium-price segment should provide the customer with a high-quality haptic experience.
The ttv team found that the answer to achieving this objective lay in the torque of the wheel used to adjust the desired air flow in the vehicle interior. The plastic cardan joint, which is directly connected to the rotary button on the operator side and to the inside of the device via blades, needs to be located in the area of the central support point. It goes without saying that the cost-benefit ratio was of utmost importance here.
The best example of our skills in the aerospace sector are the special fluorosilicone FVMQ O-rings for the drive units for the cargo-loading system used in the Airbus A380. These units were developed by Rheinmetall Defence Electronics in cooperation with the company Wittenstein.
Unlike conventional models, these drive units have two motors, meaning that lifting and rotating operations can be carried out independently. The PDUs are installed in the cargo hold of the A380s. Their main task is to provide the necessary traction to move air-freight pallets and containers in the cargo hold under all environmental conditions. The SE-PDUs are fitted with two independently driven AC servo motors. One motor provides the necessary traction, while the other motor actively moves the roller up or down.
Spring-loaded PDUs are arranged between the roller tracks in order to move pallets inside the cargo hold.
The fact that WITTENSTEIN aerospace & simulation opted to use us as their supplier in this market is something that we are very proud of, and encourages us to drive forward the development of more individual and technologically sophisticated solutions.
ttv sees enormous potential for both the automotive sector and the aerospace industry with regard to the optimisation of functional components, where ttv is the perfect solutions partner.
