As we reported on Autoline Daily, Ford has developed a new kind of front suspension that eliminates torque steer. Called RevoKnuckle, it looks. Ford’s RevoKnuckle front suspension is a re-engineered version of the McPherson setup which weighs less and costs less than a double. NASICS: RevoKnuckle suspension. 5th July hen Ford were developing the Mk2 Focus RS they had a problem to overcome. Big power (bhp), and.

In Depth: Ford’s RevoKnuckle Suspension And Quaife LSD For The Focus RS

Like all limited-slip differentials LSDsthe Quaife unit allows some degree of freedom of rotation between the two drive wheels—that’s what makes it possible to turn corners smoothly. Alfa Romeo Stelvio Quadrifoglio. Search My Stuff What’s New 3 12 24 Recommended Galleries Toyota Supra leaked, again.

Bugatti’s 3D-printed brake caliper tested to revokuckle extremes.

If is so revolutionary, then chances are Ford won’t want to tell everyone how it works. Most Popular This Week. Terms and Conditions Posting Rules. This is the future, today.

How it accomplishes this task is what revoknhckle the type of differential, and there are many ways, including helical, clutch-type and viscous coupling LSDs. A side benefit of the RevoKnuckle system is improved traction in addition to minimized torque steer thanks to greater freedom in configuring camber, caster and trail. Used Volkswagen Golf 2, cars.

Ford RevoKnuckle Suspension and Quaife LSD Explained – autoevolution

Used Ford Focus 7, forv. Get daily e-mail updates GO. The mid-size pickup truck pace-setter. Our work has shown clearly that our approach in combining a tuned RevoKnuckle with the Quaife differential is an ideal solution for a high performance front-wheel-drive road car like Focus RS.

To overcome the torque steer issue, the engineers used a standard MacPherson strut architecture, but added a two-piece knuckle that adds a ‘C’ shape to the lower suspension mount.

Thanks Dave, that has shed light on the subject. Stock photography by izmostock. PH – Shed of the Year. It allows the simplicity of a traditional McPherson strut arrangement, but with geometry settings that minimize steering disturbances and torque steer, principally a reduction in steering offset. While it may sound complex, in truth it is a simple, durable and cost-effective mechanical solution. Was hoping to see a picture or diagram, as i want to know how it works as opposed to what it does.

I agree to receive emails from the site. Latest News British Columbia: But unlike an open differential, when one wheel starts to spin at a much higher rate than the other, it steps in to keep the spin from degenerating into futile burnt rubber. I can withdraw my consent at any time by unsubscribing. Latest Features British Columbia: Anyone that’s done any significant performance work on a MacPherson-strut AWD car knows just how important – and difficult – these adjustments are to achieve.


Browse cars for sale. It is characterised by sudden turning force on the steering wheel and can be exacerbated by vehicles with wide tyres and limited-slip differentials. Ive read the story on the new Rs and was just wondering if anyone on here can shed some more light on this ‘new’ design have searched the net and found nothing.

As one wheel slips, it spins faster, and the torque differential across the two sets of gears increases, progressively locking the set that’s transferring the most torque, slowing its speed and sending more power to the wheel with more grip.

Various innovations, developed as a result of customer feedback from previous performance Fords, have allowed engineers to keep the new Focus RS as front-wheel drive, with a revoknucklr differential, while still achieving demanding targets for traction, handling and steering. Used Honda Civic 9, cars.

Used Chevrolet Cruze 7, cars. For the limited-slip diff, they called on Quaife, a standard in the field, while they tapped their own engineers for the design of the RevoKnuckle suspension.
