A vehicle drivetrain assembly, and method for making the assembly, including first and second torque transmitting members, one of which is made of aluminum and the other of which is made of steel, and being joined by an electromagnetic pulse weld progressively applied along a radial direction relative to a central axis of the assembly.

Vehicle drivetrain assembly and method for making the assembly

A vehicle drivetrain assembly () and method for making the assembly of first and second torque transmitting members (), one of which () is aluminum and the other of which () is steel, that are joined by an electromagnetic pulse weld () progressively applied along a radial direction relative to the axis (A) of assembly rotation so as to provide a lightweight construction.

A driveline system for an automotive driveline system includes a transmission device, a differential device, and a universal joint having a drive shaft presenting terminal ends and interconnecting the transmission and differential devices. A yoke is connected to each of the terminal ends of the drive shaft and presents an internal surface and an external surface having generally equal thickness defined therebetween to form a dish of the yoke having a tubular monolithic structure. The yoke portion includes a bottom and a pair of spaced lugs each presenting sloping side walls for reinforcing the lugs as said yoke is rotated around a longitudinal axis.

A method for making a differential gear casing () flow forms a first casing half () and forms a second casing half (), both with hemispherical portions (and) and with radial flanges (and) with the latter also having an axial projection (). An interior positioning surface () of the first casing half () and an exterior positioning surface () of the second casing half () position the casing halves with respect to each other.

Method for making vehicle axle differential casing and resultant product

The present invention includes a differential housing and a method for forming the differential housing. The method includes the step of cold-working a first housing preform by one of a group consisting of spin-forming or flow-forming the inner surface of the preform into conformance with a contour of a first mandrel to form the differential housing. The method also includes the step of installing a differential mechanism subassembly including a plurality of gears and a pin in the differential housing. The method also includes the step of releasibly connecting a housing portion of the differential housing with one of a lid and a second gear assembly.

Releasable enclosure for differential housing

The present invention discloses a differential housing and a method operable to form the differential housing. The method includes the step of disposing a member having an outer surface on a mandrel. The member in the exemplary embodiment of the invention is a ring that enhances the strength of the finished differential housing. The method also includes the step of cold-working a housing preform by flow-forming the inner surface of the housing preform into conformance with the mandrel and with the outer surface of the member after said disposing step. The member is disposed in situ as the housing preform is cold-worked to produce the finished differential housing.
