Bellows and articulations for buses: Innovation in motion
Located in Emilia-Romagna, in the heart of Italy’s Motor Valley, PEI Mobilty was born in a context of excellence and over the years has developed a wide range of products for interconnection, becoming a key partner for leading manufacturers of articulated buses.
Years of activity and successes in the sector have led PEI Mobility to have currently 10.000 bellows sold in Europe and worldwide, resulting in being reference partner in a high-level position on the international scene.
Made with high-tech materials, our bellows feature patented systems that ensure powerful fastening to the carriage body to guarantee ultra-smooth movement, greater reliability and increased on-board comfort.
Flexibility and efficiency are constantly supported by extensive engineering expertise, IATF automotive certification, stringent tests and calculation procedures, together with continuous research and development activities.
PEI Mobility bellows are made of UV-resistant copolymer complying with the highest safety regulations in the automotive field. A wide range of colours, in addition to the traditional grey, allows an extensive customisation. The translucent fabric option makes the vehicle’s interior more luminous, greatly improving passenger comfort.
Over the years, PEI Mobility has developed and produced several innovative systems, many of which have been patented:
• The connecting clips between bellows.
The system allows a quick and easy installation, in addition to a reliable and custom-tailored product.
• The fastening of internal bellows to the body and central hoop.
This system allows fast replacement and gives great stability to the structure.
• The innovative external bellows fixing system to the vehicle body.
It provides a quick installation, unique on the market: bellows become extremely easy to inspect and maintain.
• The special zips reduce the tension of the bottom part fabrics and ensure a more effective sealed area.
• The clip system for the bottom is easy to install and reliable.
The articulation joints by PEI Mobility are designed to guarantee safe operation on the road, optimizing the vehicle’s dynamic performance under all operating conditions and are suitable for all kinds of buses.
Specific control systems ensure vehicle stability when driving, guaranteeing passenger safety. The moving parts are designed to improve on-board comfort and smooth driving.
Digital mechanical simulations, dynamic analyses and durability tests on the road are intended for stressing the articulation joints to the limit, in order to guarantee the absolute reliability of the vehicles on which they are fitted.
The dynamic simulation in vehicle design performs an important virtual analysis and testing tool that has been supporting physical tests made in automotive industry for a long time now.
In particular, the sector of urban bus design is a theme of great interest for research in the automotive world, both in terms of performing features and considering safety and comfortable mobility for passengers.
In this specific context, the R&D department of PEI Mobility has been working since long ago with special state-of-the-art multi-body softwares, to create solutions having the primary aim to optimise road transport. Through these cutting-edge technologies and thanks to an experienced and qualified team of engineers, PEI Mobility anticipates the market needs by developing high-tech products in terms of performance and safety.
Therefore, the dynamic simulation allows PEI Mobility to examine the performance of the hydraulic damping system by actually predictive testing each bus on which it will be installed, with the imperative to meet the safety parameters established by the most authoritative safety certification bodies.
PEI Mobility thus commits to solve one of the main issues related to the design of buses, the event known as "Jackknife", typical of the articulated vehicles.
