A sealing element for a ball joint. The sealing element has a sealing area on the housing side and a sealing area a distance away therefrom in an axial direction of the sealing element on the stud side. Arranged between the housing-side sealing area and the stud-side sealing area is an outlet opening which extends through the sealing element to allow the passage of spent lubricant. The outlet opening extends in the axial direction of the sealing element, passing all the way through the sealing element in the axial direction. Further, a ball joint having a sealing element and a two-point control arm with such a ball joint.

The present invention relates to the field of drive technology and provides a space-saving possibility for determining forces or torques transmitted by a drive shaft with a journal cross of a universal joint with four journals projecting from a base, to which a strain sensor is attached for this purpose.

A universal joint bearing with at least a first and a second elastomeric ring. The universal joint bearing is free from spiral springs, which exert a force on a portion of one of the elastomeric rings. The portion is provided for abutting against a trunnion of a crosspiece of a universal joint in a condition in which the universal joint bearing is part of the universal joint.

A coupling device is provided. The coupling device may include a stem having a first end, a second end, a groove, and a threaded portion. A first engagement member may be disposed over the stem between the first end and second end. The first engagement member may be movable relative to the stem. An inner sealing member may be disposed in the groove. When the first engagement member is in a first position, the inner sealing member may be retained in the groove, seal against a surface of the stem, and may not be removed. When the first engagement member is in a second position, the inner sealing member may be retained in the groove, does not seal against the surface of the stem, and may be removed. The coupling device may include a washer, an outer sealing member, and a second engagement member disposed over the stem.

An outer ring 6a for a shell-type radial needle bearing having a cylindrical shape with a bottom is achieved for which fatigue life of the bottom plate section 9a and the continuous section between the bottom plate section 9a and the cylindrical section 8a is improved, as well as the anti-corrosion characteristic of the outer ring 6a is improved and the outer ring 6a can be prevented from coming out of the bearing without an increase in cost. After obtaining an intermediate raw material 35 having a cylindrical section and a bottom plate section from a metal raw material, shot peening is performed on the intermediate material 35 to create residual compressive stress in the surface and surface layer section on the outer surface side of the cylindrical section 8a and the bottom plate section 9a such that the residual compressive stress in the surface layer section on the outer surface side is greater than the in the surface layer section on the inner surface side, and from the surface to a depth of 0.03 mm is 700 MPa to 1600 MPa.

In order to attach cup bearings 18 with good precision in portions between circular holes 15 that are formed in joining-arm sections 10 of yokes 7a, 7b of a cross shaft universal joint 6 and the tip-end sections of a shaft section 17a of a cross shaft 8 regardless of variation in the dimensions of the joining-arm sections 10, the circular holes 15 in the tip-end sections thereof, and the cup bearings 18, and elastic deformation of the joining-arm sections 10 of the yoke 7a during press-fitting work, press-fitting punches 33 are used to pressure fit the cup bearings 18 to a preset reference position inside the circular holes 15, and the value of the pressure that is applied to the press-fitting punches at that instant is set as a reference pressure, and at the instant when the pressure applied to the press-fitting punches becomes larger than the reference pressure by a preset specified value, the cup bearings 18 are determined to have reached positions where press-fitting is complete.

A tripod constant-velocity joint includes: an outer joint member having a cavity elongated in a longitudinal direction and three roller tracks; an inner joint member having a center body and three journals outwardly radially protruded from the center body; and three roller assemblies respectively coupled to the journal in a state of being respectively disposed in the roller tracks. The respective roller assembly comprises: an inner race which is connected to the journal and is provided with a first inner ball groove and a second inner ball groove on both lateral sides thereof; a first ball array and a second ball array respectively having a plurality of balls which are respectively disposed in the first inner ball groove and in the second inner ball groove; and a ball cage which restricts movements of the first ball array and the second ball array in a longitudinal direction thereof.

A drive assembly including a wedge clutch assembly is disclosed. The wedge clutch assembly includes a first cage having a first plurality of tapered crossbars that at least partially define a plurality of tapered wedge pockets. A plurality of wedges are each arranged within a respective one of the plurality of wedge pockets and within a circumferential groove of one of an outer ring or an inner ring. The plurality of wedges each including a ramped surface facing a corresponding one of a plurality of ramps defined in the outer ring or inner ring. Movement of the first plurality of tapered crossbars in a first axial direction or a second axial direction circumferentially drives the plurality of wedges into contact with the circumferential groove such that an input drive gear drives an output.

A unitary yoke-shaft and an axle assembly having a unitary yoke-shaft. The unitary yoke-shaft includes a shaft and a yoke. The shaft extends along an axis. The yoke extends from the shaft. The yoke is integrally formed with the shaft such that the yoke and the shaft are a unitary one-piece component.

A constant velocity joint assembly integrated with a wheel hub device may include an internal race coupled to an end portion of a driveshaft, a plurality of joint balls held in the internal race, and a hub housing accommodating and coupling the internal race holding the joint balls therein, with a bearing coupled to an external circumferential surface thereof, the hub housing provided as an external race of a constant velocity joint and the wheel hub device.
