BMW And ZF Suspension Co-Develop Carbon Fiber Telescopic Fork


BMW Motorrad provides an eclectic number of front-end suspensions. From the R 18’s standard fork to the S 1000 R’s semi-active unit, from the R 1250 GS’s Telelever entrance finish to the Ok 1600 GT’s Duolever suspension, innovation ranks excessive on the Home of Munich’s precedence record.

Want extra proof? Look no additional than BMW’s newest three way partnership with suspension accomplice ZF (Zahnradfabrik). The 2 German corporations have collaborated ceaselessly up to now and so they’ve joined forces but once more to develop a carbon fiber telescopic fork for the BMW Motorrad World Endurance Staff.

Whereas carbon fiber-constructed entrance ends are commonplace in MotoGP, BMW doesn’t take part in that sequence. Consequently, BMW turned to its Endurance World Championship outfit because the take a look at mattress for its superior new part. Suspending the quantity 37 BMW M 1000 RR, the fork consists of a carbon fiber outer tube mated to a carbon fiber composite/metallic inside tube. Just like most inverted entrance ends, metallic fork legs slide throughout the carbon fiber-composed tubes.

Using the light-weight materials not solely cuts weight but in addition permits BMW and ZF engineers to govern the entrance finish’s rigidity. This permits the crew to dial within the bike’s flex and dealing with traits.

“Utilizing this materials and this know-how permits us to shift the brink at which physique vibrations happen,” defined BMW Motorrad Motorsport Director Mark Bongers. “One main focus throughout improvement was the design of the homogeneous bending hundreds. The objective being for the throttle response for the rider to be extraordinarily delicate, even beneath essentially the most excessive strains. And suggestions from the riders confirmed that the objective was achieved.”

All of the crew’s arduous work paid off when the quantity 37 BMW M 1000 RR gained the 2022 24-Hour Spa spherical of the Endurance World Championship. Whereas the brand new suspension proved its meddle on the observe, its rapid success makes us surprise if the system will spotlight the M 1000 RR sooner or later. After all, the part might want to meet strict homologation requirements earlier than that occurs, but it surely looks like the crew is nicely conscious of that truth.

“Every thing additionally must be subjected to overload, since security is the primary precedence,” admitted ZF engineer Henner Fröderking. “This reveals whether or not the calculations have been right. After which the efficiency of the part additionally has to fulfill expectations.”
