Abstract: A structure for securing a flexible boot to a face of the outer race of a constant velocity joint which includes providing the boot with a generally annular flat flange portion having a uniform thickness and a plurality of apertures formed therethrough. A securing structure includes a generally annular retaining ring having a corresponding plurality of apertures formed therethrough, with an axially extending collar portion formed about each of the apertures. The axial lengths of the collar portions are approximately 80 percent of the thickness of the boot flange. The boot is secured to the face of the outer race by disposing the retaining ring thereabout such that the collar portions extend through the boot flange apertures. Respective threaded fasteners are inserted through the retaining ring and boot flange apertures into axially extending bores formed in the outer race, which fasteners may be the way by which the joint is mounted.

Abstract: A drive shaft assembly has universal joints at each end that include flexible seal boots. The drive shaft assembly has a protective cover for the flexible seal boots in the form of a seamless woven nylon sleeve that is clamped onto the universal joint housings at each end of the drive shaft. The sleeve is tied in the middle to reduce its profile. Alternatively, the drive shaft assembly may have an individual protective cover for each flexible seal boot. These individual protective covers are also in the form of a seamless woven nylon sleeve. But these individual sleeves have a conical portion that terminates in a small diameter opening that closely surrounds the drive shaft.

Abstract: A protective bellows protects a universal joint driven by a shaft, such as forming part of the front wheel drive mechanism of a motor vehicle. The bellows has a collar with an interior annular rib which, on completion of the fitting process, locates in an annular groove in the shaft. During the fitting process, a tube is forced between the interior peripheral surface of the collar and the outer surface of the shaft, via a channel in the rib and a channel in the material of the inner end of the collar which grips the surface of the shaft. Grease is pumped into the interior of the bellows through this tube. Further channels extend through the rib and the adjacent material of the collar, and allow excess air Pressure to be vented to atmosphere during and after the grease-filling operation.

Abstract: 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.

The neck of the boot is formed with protuberances which engage the walls of outwardly-opening recesses in the forks so that when the neck is clamped down on the sleeve a force is created which urges the forks together toward each other and against the tongue, thereby forming an effective clamp which seals the neck of the convoluted boot to the shaft.

Abstract: A rack boot which is installed at the steering rack portion of an automobile comprises a small-diameter ring portion, a large-diameter ring portion, and a bellows portion interposed between the small-diameter portion and the large-diameter portion. An angle to an axial line of the boot of a slanted wall of a first crest in the bellows portion is arranged to be 70.degree. to 85.degree., whereby the slanted wall is turned in when the boot contracts to an extreme extent. As a result, the shrinkage ratio of the boot in the axial direction can be increased without any necessity to enlarge the outer diameter of the crest portion of the boot or to increase the number of crests. Consequently, the size of the rack boot can be reduced.
