Drive axle system
First Claim
Patent Images
1. A drive axle system comprising:
- a first drive axle assembly that includes;
an input shaft and an output shaft that rotate about a first axis;
a first ring gear that rotates about a first ring gear axis and provides torque to a first wheel axle; and
a first pinion that rotates about a first pinion axis and that is operatively connected to the input shaft and the first ring gear such that the first pinion provides torque from the input shaft to the first ring gear; and
a second drive axle assembly that includes;
a second ring gear that rotates about a second ring gear axis and provides torque to a second wheel axle; and
a second pinion that rotates about a second pinion axis and that is operatively connected to the output shaft, wherein the second pinion provides torque from the output shaft to the second ring gear;
wherein the first pinion axis is disposed parallel to the second pinion axis, the first axis is coplanar with the second pinion axis, and the first axis and the second pinion axis are not coplanar with the first pinion axis.

10. A drive axle system comprising:
-
a first drive axle assembly that includes; an input shaft and an output shaft that rotate about a first axis; a drive gear that is disposed on the input shaft; a first ring gear that rotates about a first ring gear axis and provides torque to a first wheel axle, wherein the first ring gear has a first front surface and a first set of ring gear teeth that are arranged around the first ring gear axis and extend away from the first front surface; a first pinion that rotates about a first pinion axis and that provides torque to the first ring gear; and a driven gear that is disposed on the first pinion and that engages the drive gear; and a second drive axle assembly that includes; a second ring gear that rotates about a second ring gear axis and provides torque to a second wheel axle, wherein the second ring gear has a second front surface and a second set of ring gear teeth that are arranged around the second ring gear axis and extend away from the second front surface; and a second pinion that rotates about a second pinion axis and that is operatively connected to the output shaft, wherein the second pinion provides torque from the output shaft to the second ring gear; wherein the first front surface faces toward the second front surface. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
