Abstract
A motor vehicle interaxle differential including a bevel gear design and utilizing an interaxle differential housing having a one-piece construction. A splined input shaft extending from the motor vehicle transmission mates with the inside diameter of a splined trunnion on the interaxle differential housing to provide input torque. The interior of the interaxle differential housing includes four (4) substantially flat thrust surfaces for support of left and right side gears and first and second pinion mate gears. The first pinion mate gear and the second pinion mate gear are retained in the interaxle differential housing by stub shafts which are threaded into the interaxle differential housing wall. The stub shaft design includes a shoulder to provide controlled perpendicularity and torque retention and a recessed socket head to facilitate installation. A housing endcap is utilized for sealing and supporting the interaxle differential housing bearing and the input shaft.
