摘要
A rolling or convoluted boot for a constant velocity universal joint has at least one pressure balancing aperture (19, 19a) located in a pressure balancing region (13, 13a). When the shaft (12) is in a stationary position, the pressure balancing region (13) tightly adjoining the shaft (12), during shaft rotation, the pressure balancing region radially lifts off the shaft as a function of the speed or pressure differential. Thus, the boot balances pressure between the joint space and the surrounding atmosphere.
