Patent ID: 6912926

Claim:
A gear transmission comprising: a first shaft, an intermediate shaft which is parallel to the first shaft, a first cylindrical pinion having a first set of teeth and which is mounted to rotate with the first shaft, a second cylindrical pinion having a second set of teeth and mounted to rotate with the intermediate shaft, the first and second sets of teeth of the first cylindrical pinion and the second cylindrical pinion having the same number of teeth and the same diameter and meshing with one another, a third cylindrical pinion which is mounted to rotate with the first shaft, a fourth cylindrical pinion which is mounted to rotate with the intermediate shaft, the sets of teeth of the third cylindrical pinion and the fourth cylindrical pinion having the same number of teeth and the same diameter, a double-toothed face gear having face gear teeth being mounted between and respectively meshing with the sets of teeth of the third cylindrical pinion and the fourth cylindrical pinion, the double-toothed face gear able mounted to rotate about a second shaft which forms an angle with the first shaft, wherein the double-toothed face gear is provided with coupling teeth for slideably coupling the rotation of the double-toothed face gear to the rotation of the second shaft, and the direction of the coupling teeth being perpendicular to a plane of the face gear, and the double toothed face gear being slideably mounted on a housing of a differential of a vehicle.
