The invention relates to a method for producing a transmission shaft (1) comprising a body (2) made from composite and a coupling piece (3) at one end of the body (2), said coupling piece (3) being hollow and having splines (4) on the inner surface thereof, the base (6) of the splines (4) delimiting the perimeter of a circle of diameter D2 and the head (5) of the splines (4) delimiting the perimeter of a circle of diameter D1, characterized in that said method comprises the successive steps of:—providing a mandrel (10) having an expandable part (12) and a non-expandable part (11);—producing the body (2) by winding pre-impregnated fibre filaments around the mandrel (10);—positioning the coupling piece (3) around the body (2) on the expandable part (12) of the mandrel;—expansion of the expandable part (12) of the mandrel (10) in order to fill the base (6) of the splines (4) with the impregnated fibres of the body (2);—curing the body (2) provided with the coupling piece (3).

A bearing structure includes a bearing that supports a propeller shaft, an annular vibration isolating member fitted over the bearing, an outer ring attached to the vibration isolating member and having an outer-peripheral fitting surface, and a bracket attached to a vehicle body and having an inner-peripheral fitting surface that is fitted to the outer-peripheral fitting surface. Both the bracket and the outer ring are formed of an aluminum material. An anodized aluminum layer is formed on at least one of the inner-peripheral fitting surface and the outer-peripheral fitting surface. Because of the above mentioned features, the bearing structure that has a light weight and is inexpensive and productive.

A mechanical part configured to be placed under torque. The mechanical part includes an inner tube having, a corrugated web, and an outer shell. The inner tube has an outer tube circumference, a tube axial direction, and a tube length. The corrugated web has a plurality of peaks and a plurality of troughs, a height measured as a difference between one of the peaks and one of the troughs, and a web length perpendicular to the height and in the tube axial direction. The outer shell has an inner shell circumference, an outer shell circumference, and a shell length. The plurality of troughs is affixed to the outer circumference of the inner tube. The plurality of peaks is affixed to the inner shell circumference of the outer shell. The web length is aligned with the tube length and the shell length.

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. There is also a method of forming a drive shaft.

Elastic joint comprising:—an inner ring (1) provided with an axial opening (11) for being mounted on a shaft “E” and with an outer surface having: two opposite intermediate sections (13) having a decreasing cross-section towards opposite ends of said inner ring (1) and forming supporting zones for the metal wire cushions (3), and two end sections (14) having a smaller cross-section than the central section;—an outer ring (2) provided with an outer cylindrical surface (21) for mounting the ring to on a support (S) and with an inner surface with two intermediate portions (22) having a decreasing cross-section towards opposite ends of the outer ring (2), facing the intermediate sections (13) of the inner ring (2); and—metal wire cushions (3) arranged between the inner ring and the outer ring (2).

A hybrid module includes a first component, a second component, a first bearing, and a retainer. The first component has a pilot surface and a threaded portion, and the second component has a shaft and a tool. The tool has a first drive profile. The first bearing is installed on the pilot surface and the retainer is threaded onto the threaded portion. The retainer has a second drive profile, complementary to the first drive profile. A second bearing may be installed between the first component and the shaft, and a retaining ring may be installed in the shaft or the first component to prevent axial displacement of the shaft relative to the first component. The retainer may be disposed on a first axial side of the first bearing, and the second bearing may be disposed on a second axial side of the first bearing, opposite the first axial side.

In a propeller shaft, a crowning portion of a male spline portion is provided in a predetermined range including a front end portion in an axial direction, and a tooth tip surface is shaped in such a manner that a tooth thickness thereof gradually increases from the front end portion toward an intermediate portion of the male spline portion in the axial direction.

An axle assembly of a vehicle including a differential assembly, a first axle tube including a proximal end adjacent the differential assembly, an opposite distal end, and an axle bore extending therebetween, a first axle shaft rotatably received in the first axle tube, the first axle shaft including a proximal end disposed in the differential assembly, and an opposite distal end extending outwardly from the distal end of the first axle shaft, and a radial bearing assembly including an inner cup, an outer cup and a plurality of roller elements rotatably received therebetween, the outer cup being axially fixed within the axle bore of the first axle tube and the inner cup being axially fixed to the first axle shaft.

Systems are provided for an axle arm including a lubricant reservoir and a driveshaft.
