Abstract

A hypoid gear set for a vehicle drivetrain includes a pinion gear in meshing engagement with a ring gear. The hypoid gear set has a negative pinion offset. The hypoid pinion and ring gears provide a predetermined gear ratio that can be varied up to a fifty percent faster ratio within a single carrier packaging envelope defined by a maximum ring gear diameter.

Claims (14)

1. A vehicle axle comprising:

a hypoid pinion gear having a first number of spiral gear teeth and an outer diameter; and

a hypoid ring gear having a pinion gear engagement side with a second number of spiral gear teeth and a pitch diameter wherein the spiral gear teeth of the ring gear are in meshing engagement with the spiral gear teeth of the pinion gear, wherein a ratio of the pitch diameter to the outer diameter is greater than a ratio of the second number to the first number, and

wherein when viewing the pinion gear engagement side of the ring gear with the pinion gear to the right of a ring gear vertical axis, the pinion gear engages the ring gear in a manner selected from the group consisting of:

(a) the pinion gear is offset below a horizontal axis of the ring gear and the pinion gear spiral gear teeth are right-handed; and

(b) the pinion gear is offset above the horizontal axis of the ring gear and the pinion gear spiral gear teeth are left-handed.

2. The axle of claim 1 , wherein the pinion gear spiral gear teeth are right-handed and the ring gear spiral gear teeth are left-handed.

3. The axle of claim 1 , wherein the pinion gear spiral gear teeth are left-handed and the ring gear spiral gear teeth are right-handed.

4. The axle of claim 1 , wherein the pitch diameter is in a range of 100 mm to 600 mm.

5. The axle of claim 1 , wherein the ring gear teeth have a spiral angle between 30 and 50 degrees.

6. The axle of claim 1 , further comprising a carrier housing, wherein the ring gear is disposed within the carrier housing.

7. The axle of claim 1 , wherein the axle is a commercial vehicle axle.

8. The axle of claim 1 , wherein the axle is an off-highway vehicle axle.

9. The axle of claim 1 , further comprising an axle housing and a carrier housing.
