Abstract: A drivetrain assembly for a motor vehicle including a venting system. The drivetrain assembly includes an output shaft from a vehicle prime moreover component such as a transmission or transaxle. The output shaft is coupled to a propeller shaft through a constant velocity joint (CVJ) assembly. A flexible sealing boot encloses the CVJ between the output shaft and the propeller shaft. Internal components of the CVJ are vented by a first longitudinal passageway exposed to the internal volume of the CVJ extending longitudinally along the output shaft. A second radial passageway joins the longitudinal passageway and extends to the radially outer surface of the output shaft forming a second aperture. The passageways combine to provide pressure equalization between the CVJ internal volume and the atmosphere. An optional semi-permeable membrane may be mounted at the second aperture.

Abstract: A sealing boot assembly comprises a flexible boot having a first end in sealing engagement with an outer surface of a shaft to define an inner chamber therein. A venting orifice extends from the inner chamber through the flexible boot to ambient and a moisture-blocking, vapor-breathable membrane is disposed across the venting orifice between the inner chamber and ambient to vent gas from the inner chamber during high temperature operation of the shaft and to allow air to returns to the inner chamber upon cooling thereof.

Abstract: A vent valve for a constant velocity joint is disclosed. The vent valve may generally include a body disposed in a bore of the cover which is axially movable in the bore and allows fluid flow through the bore, a first umbrella portion associated with a side of the body which defines a first gap between a first surface of the cover and the first umbrella portion, and a second umbrella portion associated with an opposite side of the body which defines a second gap between a second surface of the cover and the second umbrella portion.

Abstract: A boot for a universal joint is constructed by a boot body and a boot adapter. The one end of the boot is fitted on a propeller inner shaft via its one-end fitting portion and the other end of the boot is fitted on the outer race of the universal joint via its other-end fitting portion, thereby substantially covering the universal joint. The foregoing one-end fitting portion has an annular lip portion at its end portion. Passages for flowing air are formed on the one-end fitting portion and its annular lip portion, respectively. The passages communicate with each other through an annular partial passage between both passages. The existence of the annular partial passage increases the flowing resistance of air between the inside and the outside of the boot to reduce the pressure fluctuation in the boot and to improve the effectiveness in preventing splashed water or muddy water from intruding into the boot along with the suction of air.

Abstract: A protective constant velocity (CV) joint boot having a tubular body with end openings and one longitudinal seam running from one end opening to the other enables rapid replacement of existing monolithic CV joint boots. Additionally, reinforcement of the tubular body of the protective boot against stresses caused by movement of the joint is accomplished through the use of a pair of sealing sleeves, also having seams, which are fitted under the tubular body of the protective boot. The edges of the seam of the tubular boot interlock with, as seen in cross section, an arrow head shaped male member on one edge of the seam which locks past a pair of nubs on a female retaining edge of the seam. The seams of the sleeves are off-set with the seam of the tubular body of the protective boot, thus accomplishing a more effective seal. Both sleeves have a flange that lends strength to the crests nearest the ends of the protective boot, which under most driving conditions receive more stress than the central portion. The protective boot does not require removal or replacement of any suspension or brake components during the replacement of a damaged or worn boot.

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.
