Definitions
- the present invention relates generally to motor vehicle shaft joints, and more particularly concerns a rolling radial boot for a direct torque flow constant velocity joint.
- Constant velocity joints connecting shafts to drive units are common components in automotive vehicles.
- the drive unit typically has an output shaft or an input shaft for receiving the joint.
- the drive unit is an axle, transfer case, transmission, power take-off unit or other torque device, all of which are common components in automotive vehicles.
- one or more joints are assembled to the shaft to form a propeller or drive shaft assembly. It is the propeller shaft assembly, which is connected, for instance, at one end to the output shaft of a transmission and, at the other end, to the input shaft of a differential.
- the shaft is solid or tubular with ends adapted to attach the shaft to an inner race of the joint thereby allowing an outer race connection to a drive unit.
- the inner race of the joint is typically press-fit, sp lined, or pinned to the shaft making the outer race of the joint available to be bolted or press-fit to a hub connector, flange or stubshaft of the particular drive unit.
- the same typical or traditional connection is made to a second drive unit when connecting the shaft between the two drive units.
- the joint may be coupled to a shaft for torque transfer utilizing a direct torque flow connection. Regardless of the connection type, constant velocity joints require, for improved joint life, a sealed environment.
- Elastomer boots of the flexible or soft type improve the life of a constant velocity joint by sealing out contaminates and retaining joint lubrication.
- Elastomer boots are primarily used for sealing two parts that can be articulated relative to one another and which, more particularly, rotate at the same time. These parts constitute a joint.
- a typical application refers to sealing joints of the constant velocity and universal types. For this purpose, a boot with a cylindrical portion, typically having a smaller diameter is slipped on to a shaft connected to a first joint component, and an annular portion -with a greater diameter is connected either directly or via an intermediate element to a second joint component.
- the wall has the shape of half a torus for a roll boot, and has a bellows shape for a convoluted boot.
- the radius of curvature of the wall decreases on the inside of the angle and increases on the outside of the angle.
- the change in curvature in the roll boot wall moves across the circumference, so that during a complete 360 degree rotation, each point of the boot wall passes through a curvature maximum and a curvature minimum causing flexing of the boot wall. Flexing also occurs for each rotation of the roll boot due to gravitational and centripetal forces.
- the flexing action may increase material decay caused by mechanical, chemical and thermal attack related to the environment in which the boot is used.
- a roll boot may be prone to puncture or tearing due to external debris.
- the roll boot may blow out or rupture when subjected to increased lubrication pressure when used in high-speed or high angle joint seal applications.
- the present invention provides a rolling radial boot for a direct torque flow constant velocity joint.
- the rolling radial boot includes a rigid shroud that covers the rolling radial boot.
- the rigid shroud provides the benefit of supporting the rolling radial boot while sealing a constant velocity joint (CVJ) thereby making the rolling radial boot less prone to puncture or tearing.
- CVJ constant velocity joint
- the inventive rolling radial boot with the rigid shroud may be used with CVJ assemblies having shaft to drive torque transfer utilizing direct torque flow connectors.
- the rolling radial boot may include improved boot blow out or rupture protection when subjected to increased internal joint pressure.
- the rolling radial boot being supported by the rigid shroud may overcome flexing caused by gravitational or centripetal forces thereby extending the life of the boot.
- a direct torque flow constant velocity joint having a rolling radial boot includes a DTF CVJ connector, a shroud assembly and a rolling radial boot.
- the DTF CVJ connector includes an outer joint part and an inner joint part, such that the shroud assembly is connected to the inner joint part and substantially surrounds the outer joint part of the DTF CVJ connector.
- the shroud assembly includes a circumferential clamp portion so that a rolling radial boot is connected between it and the outer joint part of the DTF CVJ connector.
- the rolling radial boot is covered by the shroud assembly and seals the DTF CVJ connector.
- the shroud assembly also protects the boot from external debris.
- the shroud assembly of this embodiment includes a rigid shroud supported by a support member.
- the shroud assembly includes a rigid shroud containing a support member.
- the present invention provides a direct torque flow CVJ with a rolling radial boot.
- the present invention itself will be best understood by reference to the following detailed description and taken in conjunction with the accompanying drawings.
- Figure 1 shows a plan view of an exemplary drive system for a typical 4-wheel drive automobile wherein the present invention may be used.

- a propeller shaft 26 connects the front differential 20 to a rear differentia] 28 wherein the rear differential 28 includes a rear right hand side shaft 30 and a rear left hand side shaft 32, each of which ends with a wheel on one end thereof. Constant velocity joints 10 are located on both ends of the half shafts 30, 32 that connect to the wheels and the rear differential 28.

- the propeller shaft 26 includes interconnecting shafts 23, 25, 27.

- the constant velocity joints 10 may be any of the standard types known, such as a plunging tripod, a cross groove joint, a fixed ball joint, a fixed tripod joint, or a double offset joint, all of which are commonly known terms in the art for different varieties of constant velocity joints 10.
- the constant velocity joints 10 allow for transmission of constant velocities at angles typically encountered in every day driving of automotive vehicles in both the half shafts, interconnecting shafts and propeller shafts of these vehicles.
- each Cardan joint 34 may be replaced with any other suitable type of joint, including constant velocity joint types.
- the direct torque flow constant velocity joint with a rolling radial boot of the present invention may be utilized to advantage for any of the above mentioned joint locations.
- the shafts 22, 23, 24, 25, 27, 30, 32 may be solid or tubular with ends adapted to attach each shaft to an inner race or an outer race of a joint in accordance with a traditional connection, thereby allowing the outer race or inner race to be connected to a hub connector 36, a flange 38 or stubshaft 40 of each drive unit, as appropriate, for the particular application.
- any of the traditional connections identified in Figure 1 at 10 or 34 may be direct torque flow connections in accordance with a first embodiment ( Figure 2) or a second embodiment ( Figure 3) of the present invention.

- a welded connection would be a fixed connection example.
- a DTF connection refers to the inner race coupling to the shaft of a drive unit, such as a differential, transmission or transfer case without limitation, as opposed to the traditional connection mentioned above.
- the connection type may be divided into two styles of DTF connection types, i.e. direct or indirect, as described in United States Patent Application titled "Direct Torque Flow Constant Velocity Joint with Male Connector” filed on November 29, 2005, and incorporated by reference herein.
