alia an increased range of movement between the rotational axes of two interconnected rotating members reduced vibration between the members as well as the ability to transmit increased loads between the members in the following description one embodiment of the invention is set forth in the context of replacing a cruciform type universal joint assembly in an automotive drive linkage with a ring type universal joint assembly it will be appreciated however that certain aspects of the invention are not limited to such applications fig1 shows a side view of the adapter 40 of the present invention as shown the adapter 40 has a first interface surface 41 that is designed to engage a yoke member interconnected to a rotating member this yoke member may be interconnected to a power output a power input a shaft a hub or any other member that rotates to transfer power in any case the yoke member is originally designed to receive opposing torque transfer elements e g trunnions typically on a cruciform connector as will be more fully discussed herein an opposing second interface surface 43 is designed to be received within a ring member of a ring joint assembly in this regard the adapter allows a yoke member designed for use with a cruciform connector to be converted for use with a ring type yoke fig2 shows a cruciform joint assembly 200 for transmitting rotary power from a transmission 110 of an automobile to an output shaft 150 e g a drive line as shown the cruciform joint assembly 200 includes a cruciform connector 140 having four radially extending torque transfer elements each of which is covered by a coaxially aligned bearing cap a first set of opposing torque transfer elements 142 a b only one shown on.
