TAPERED BEARING STABILIZER BAR

Stabilizer bars are utilized to provide additional roll resistance during cornering events while allowing for a

lower spring rate when impacting a bump with both wheels of the same axle. The bar is typically

connected to each wheel via a link, and to the body via two rubber bushings. The interface between the

bushings and the stabilizer bar is frequently the source of noise issues during vehicle use. The rubber on

metal interface causes noise as the bar is articulated. Further, by utilizing bearings instead of rubber

bushings, lateral tolerances can be improved.

This invention utilizes two taper bearings in place of the bushings which are typically used to mount a

stabilizer bar to the frame/body of a vehicle. By using bearings, torsional stiffness can be significantly

reduced compared to a rubber bushing that is bonded to the bar and/or outer bracket. This would result in

reduced noise when compared to a bushing that isn’t bonded, and reduced torsional spring rate when

compared to a bonded bushing. The inner race of the taper bearing would be mechanically bonded to the

stabilizer bar. This would prevent any motion between the bar and the inner race. The outer race of the

plastic bearing could then be assembled over the inner race. The outer race could be bonded to a rubber

bushing to provide additional isolation, while still allowing the moving interface to be between the two

faces of the bearing. A bracket would be placed over the assembly...
