An assembled half shell-shaped flanged bearing shell for a crankshaft bearing point in an internal combustion engine, having a half shell-shaped radial bearing part and having a disk-shaped axial bearing part that is fastenable in the area of an axial end-face side of the radial bearing part. The axial bearing part is formed from at least three segments that adjoin one another in the circumferential direction and that are nonreleasably joined together via a weld seam between every two segments, wherein the respective weld seam does not include the radial bearing part. The segments with their retaining tongues are first arranged on the edge area of the radial bearing part so that the retaining tongues engage with the respective retaining recesses in the edge area of the radial bearing part, and only then is the respective weld seam applied between every two segments, as a result of which the axial bearing part thus formed is captively held on the radial bearing part but with slight play, and in particular without the retaining tongues or the edge area of the radial bearing part having been machined in a material-shaping manner.

A bearing seal assembly includes at least one seal unit and at least one pulse wheel attached to the seal unit in an interference-fit and/or a materially bonded manner. The seal unit may include a radially outer member surrounding a radially inner member, the radially inner member may have a cylindrical seal surface and a flange projecting radially outwardly from an end of the seal surface and the radially outer member may have a metal profile element at least partially covered by an elastomer body that defines a first seal lip that directly contacts the cylindrical seal surface of the radially inner member. The pulse wheel may be attached to the radially outer member by a radially inwardly directed flange of the metal profile element overlying a radially outer edge of the pulse wheel.

A damping device for connecting a bearing housing to a bearing outer race is provided. The damping device may permit an allowable range of radial movement of the bearing. The damping device has an elastomeric body connected to one of the bearing outer race and the bearing housing and a cover portion connected to the other one of the bearing outer race and the bearing housing. It also has two or more deformable fluid chambers fluidly connected to one another via at least one orifice and in which fluid is encapsulated. The damping device may dissipate at least partially vibrations travelling between the bearing housing and the bearing outer race by compressing its elastomeric body and by discharging fluid from one fluid chamber to another. There may be a plurality of such damping devices disposed circumferentially about the bearing outer race.

A drive shaft is for selectively connecting a drive input to an output. The drive shaft has a tubular portion, a first diaphragm member, and a second diaphragm member displaced axially along the shaft from the first diaphragm member. The first and second diaphragm members each are formed with two axial ends. At least one undulation extends radially of the ends. The tubular portion connects the first and second diaphragm members. The first and second diaphragm members and the tubular portion are formed of fiber-reinforced polymer matrix composites. The first and second diaphragm members are connected to first and second axial ends of the tubular portion through a mechanical connection at joints. A method of forming a drive shaft is also disclosed.

The invention relates to an automobile drive shaft bushing, comprising a bushing body, wherein, a connecting cavity is arranged in the bushing body, a first annular flange and a second annular flange are arranged in the middle of the bushing body, multiple fixing holes are arranged on the peripheral surface of the first annular flange and the second annular flange, the fixing holes are communicated with the connecting cavity, the bushing body is sleeved on the drive shaft, multiple connecting holes corresponding to the fixing holes are arranged on the peripheral surface of the drive shaft. Thus, the shaft bushing and the drive shaft are connected firmly; meanwhile, two ends of the bushing body are welded to the junction of the drive shaft with a circular welding method, which ensures the sealing property of the connection between the ends of the bushing body and the drive shaft.

A drive shaft is formed by welding two spline shaft heads to a hollow middle section of tubing. The spline shaft head includes teeth which are crowned to permit an angular offset of the drive shaft relative to cylindrical splines of connectors, such that the end faces of the teeth define a barrel shape. The teeth of the spline shaft head include a side face curvature, defining a football-shaped tooth cross-section. Torque is rotationally transmitted across a permitted angular offset of the drive shaft relative to cylindrically arranged linear splines of drive and driven connectors (i.e., relative to the engine output axis of rotation and the differential input axis of rotation), thereby avoiding the use of prior art universal joints.

The bearing comprises a first ring (16) and a second ring (18) centered on an axis, each of the first and second rings being provided with an outer cylindrical surface (16b), with an inner cylindrical surface (16a), and with lateral faces (16c) which axially delimit the outer and inner cylindrical surface. One of the inner and outer cylindrical surfaces (16a) and/or one of the lateral faces (16d) of the first ring comprise a textured area (40, 42) provided with at least two first and second parallel grooves extending radially and axially, with a single inner protrusion disposed between and along the two parallel first and second grooves, with a first lateral outer protrusion disposed alongside the first groove, and with a second lateral protrusion disposed alongside the second groove, the first and second lateral outer protrusions extending respectively along the first and second grooves.

A method of producing a chassis module (1) with a structural component (3) having a through-going aperture (5) into which a ball joint housing (7) is inserted. An outer periphery of the ball joint housing (7) is connected all round to an edge section (9) of the aperture (5) by a first material-cohesive joining (11) without a filler. In order to stabilize the ball joint housing (7) in the aperture (5), the ball joint housing (7) is additionally connected all round to an inner wall section (13) of the aperture (5) at a location spaced away from the edge section (9), by a second material-cohesive joining (15) without a filler. The chassis module (1) is produced by the method, and the chassis module is in the form of a flanged connector (1) or a multi-point link.

A bushing formed of different alloys selected to accommodate different operating conditions is provided. For example, the bushing could include an iron-based alloy in a portion of the bushing exposed to lower temperatures, and a cobalt-based alloy in a portion of the bushing exposed to higher temperatures. The first and second alloys could be axially or radially aligned. The iron based alloy includes 10 to 30 wt % Cr, 0 to 21 wt % Ni, 0 to 10 wt % Mo, 0 to 5 wt % W, 0 to 3 wt % C, 0 to 4 wt % V, 0 to 20 wt % Co, and a balance of Fe; and the cobalt based alloy includes 10 to 30 wt % Cr, 5 to 21 wt % Ni, 0 to 10 wt % Mo, 0 to 10 wt % W, 0 to 3 wt % V, 0.5 to 3 wt % C, and a balance of Co.
