At least one of the pinion gears and side gears is formed from a heated tubular preform in a forging die. A method for manufacturing a differential assembly is also provided.
Claims20
A differential assembly for a motor vehicle, the differential assembly comprising:
- a rotatable case;
- a plurality of pinion gears rotatably coupled to the case;
- a plurality of side gears rotatably coupled to the case, each of the side gears being in meshing engagement with each of the pinion gears, wherein at least one of the pinion gears and the side gears includes net-shaped teeth.
An axle assembly for a motor vehicle, the axle assembly comprising:
- a housing;
- an input gear rotatably supported by the housing;
- a differential assembly being rotatably supported by the housing and including a ring gear mounted on a case, the ring gear being in meshed engagement with the input gear, the differential assembly further including a pair of pinion gears rotatably coupled to the case and a pair of side gears rotatably coupled to the case, each of the pinion gears being in meshed engagement with each of the side gears, wherein one of the ring gear, the pinion gears and the side gears includes net-shaped teeth.
A differential assembly for a motor vehicle, the differential assembly comprising:
- a rotatable case;
- a pair of pinion gears rotatably coupled to the case;
- a pair of side gears rotatably coupled to the case, each of the side gears being in meshing engagement with each of the pinion gears, wherein at least one of the pinion gears and the side gears includes net-shaped teeth having drivable contact surfaces circumferentially spaced apart from one another.
