Formula Student Germany
Top performance with polymer plain bearings
In this year's Formula Student Germany international design competition, the lightweight construction of the vehicle was one of the most decisive criteria. 3,380 students in 119 teams from 25 nations met at the Hockenheimring at the beginning of August to test their racing cars in the categories of combustion engine, electric drive and autonomous driving and compete against each other. The requirements in all three categories are the same: the mechanics must be lightweight, maintenance-free and durable.
Many student teams rely on the lightweight, lubricant-free and maintenance-free plain bearing technology from igus. The iglidur Tribo polymers are used in the pedals, steering or even in the chain drive and bring the sports cars to the finish line quickly and easily.
Tribo-polymers improve the technology
Lubricant-free and maintenance-free bearings made from the tribo-polymer iglidur X are used in the control system of the PWR Racing Team of the TU Wroclaw. These replace heavy and large metal bearings, for which a special assembly tool was required. The corrosion-free bearings can even withstand high mechanical loads and moisture. But the young designers rely on the iglidur bearings and the self-adjusting igubal spherical plain bearings not only in the control system, but also in the suspension.
Quickly printed, quickly to the finish line
This year, the team from Weingarten University of Applied Sciences chose a converted PC40 four-cylinder motorcycle engine for their racing car. However, with 86 hp and an increased displacement, the team encountered space problems: to accommodate the engine, they experimented with special components such as plastic pinions as chain tensioners in the chain drive. This was followed by the problem of the long delivery time for the parts. In their search for a suitable solution, the engineers finally found what they were looking for at igus: Low-cost, low-wear sprockets from the SLS printer. After a simple configuration, the pinions were printed from the high-performance plastic iglidur I6 and delivered in less than 72 hours.
Compact solutions for small installation spaces
The team at the Karlsruhe Institute of Technology was also looking for a compact solution for their pedal box. "As the pedal box has to be built in an extremely small space, but the components twist against each other, we needed a space-saving solution," explains Hannah Decker, from the chassis department of the KA Racing team. "We were able to achieve this with the iglidur bearings." But the bearings are not only found in the pedal box, the wear-resistant bearings are also used in the brake pedal and accelerator pedal bearings as well as in the sensor connection of the brake pedal.
young engineers support promotes innovative projects
In addition to these three teams, the company's young engineers support (yes) sponsors numerous Formula Student teams worldwide. With its university initiative, igus aims to support pupils, students and lecturers with free samples, sponsorship and the development of innovative projects.
