With the F1 back in town this weekend showcasing the pinnacle of automotive technology, we can cast our minds back 30 years to an innovation from the Williams team that was banned because it was too fast.
The Williams FW15 was already dominant in 1993, with a highly technical car and fully-active suspension. Not content to rest on their successes, the team designed and built a version of their Renault-powered machine with a constantly variable transmission (CVT) that kept motor power and torque at their peak.
The CVT version of the FW15 was around two seconds per lap faster than the standard transmission version.
Our Reeves mechanical variators employ the very technology that was banned in Formula One.
The full range of RAN Bonfiglioli bevel gearbox catalogues can be downloaded by clicking the link at the bottom of the page.
The RAN range from Bonfiglioli offers a series of mitre bevel gearboxes with options for shaft arrangement, shaft direction of rotation, and input style.
One significant benefit is that RAN gear units in frame sizes 8, 15, 18.14, 20, 20CAVO, and 25 are packed with “long life” synthetic grease.
Sizes RAN 24, RAN 1, RAN2, and RAN2R factory filled with “long life” synthetic oil. In the absence of contamination, periodical oil changes are not required.
