Abstract
A force-transmitting device comprising an aluminum alloy shaft portion, a steel end portion, and a transition portion having a first portion of aluminum alloy and a second portion of steel which is bonded to the first portion at a bonded joint. The shaft portion is welded to the first portion and the end portion is welded to the second portion, forming an integral force-transmitting device. The device is configured to transmit a force between the shaft portion and the end portion by way of the bonded joint. A device constructed in accordance with the present from two different metals achieves weight savings over prior art single-metal devices, and is simpler to fabricate than prior art two-metal devices.
