Motor sports
On the racetrack, every gram and every millisecond counts.
The same goes for the gearbox.

Motorsport is the toughest test for drivetrain technology: maximum power density with minimum weight, the highest loads in the shortest possible time, and zero tolerance for failures. Gearboxes in motorsport must be extremely light, extremely robust and extremely precise all at once – a contradiction that can only be resolved through well-thought-out design.

CHEMNITZER ZAHNRADFABRIK is a long-standing development partner in motor racing and has successfully supported innovation processes for small-batch production and prototypes. What works on the racetrack proves itself under real-world conditions – and feeds back into our series production projects.

Typical requirements for the gearbox

• Maximum power density with minimum weight – every gram counts
• Maximum load-bearing capacity under dynamic, shock-like load peaks
• Precise power transmission without play for direct responsiveness
• Short development and production times for prototypes and small-batch projects
• Material selection and manufacturing processes for lightweight construction concepts (e.g. titanium, high-strength steels)

What we offer

We develop motorsport gearboxes with a focus on weight and performance optimization – from the initial concept right through to a gearbox ready for installation. Our experience with prototypes and small-batch projects in motorsport makes us a responsive and pragmatic partner who delivers even under time pressure.
As a sponsor of the WHZ Racing Team at Zwickau University of Applied Sciences, we demonstrate that motorsport drives us not only as a market but also as a passion.

Typical gearbox types and application examples

• Weight- and performance-optimized planetary gearboxes for motor-generator units
• Weight-optimized spur gearboxes for electric racing cars
• Special-purpose gearboxes for test bench applications in vehicle development
