Lighter and lighter...

Weight savings in vehicles hold the key to conserving innumerable resources – not only when manufacturing components, but also when it comes to the related fuel savings en route. Weight-optimised car brake discs have been in serial production at Buderus Guss since 2009.

 

The Buderus lightweight brake disc is a composite disk, with the friction ring and hat connected via stainless steel bars.

 

The benefit here is that the friction ring is free to expand in response to temperature with respect to the jointing, which would be impossible for conventional brake discs. Independently of the aluminium hat, the friction ring also boasts optimal weight saving.

Development – making ideas work

For Buderus Guss, developing brake discs means breaking new ground in structural and material fields.
As a professional partner to the automotive industry, we have spent decades striving to develop brake discs that meet the requirements of today and as well as tomorrow. And luckily we have strong partners backing our quest.


Prototypes for trials can be constructed in minimal time and, right from the first casting, pave the way for subsequent serial production, since the moulding and casting processes are performed at the serial production plants, which means the results of the trial are entirely applicable to serial produced units.


Buderus Guss plays a major role in the development of lightweight brake discs, a sector bound to become ever-more crucial in future. Tailored to individual customer requirements, our engineers have developed a series of different lightweight brake discs for cars, getting them ready for serial production.
Over the past decade, we have been an integral part of the collaboration behind numerous new vehicle model start-ups during serial launches featuring very well-known automotive manufacturers.
