Abstract: A bevel gear differential, also referred to as an "open" differential, is modified by asymmetrically distributing bevel pinions around a central axis of a pair of side bevel gears. The asymmetrically distributed pinions generate imbalanced radial forces acting on the side gears, which are converted into increased frictional resistance to differentiation. The force imbalance is managed at frictional interfaces to support a wider range of performance options.

Abstract: This transmnission differential of the type comprising a two-piece differential case defined by a cup-shaped case member and a side member integrally formed with a ring gear to thereby increase the strength of the ring gear and case. The side member is bolted onto the cup-shaped case member.

The pinion shaft is secured against rotation by a pin trapped in a bore formed in the case when the ring gear side member is mounted to the cup-shaped case member. Because the cup-shaped case member is formed with a flat mating surface, the present invention does not require eyebrows formed into the case for drilling points where the bolt is received in the case.

Abstract: This invention provides a differential gear that permits a sure differential limitation effect to be obtained with a simple structure and that is both compact in size and low in price. That is, when a rotational difference occurs on a pair of output-side rotary bodies arranged in opposite form to each other on the shaft center of an input-side rotary body, a differential rotation of each output-side rotary body is achieved by interconnecting the rotary motion of each output-side rotary body by means of numerous grooves and numerous balls fitted to these grooves. At this time, when the force necessary to cause a rotational difference is given to each output-side rotary body only from one output-side rotary body, the balls or grooves of the driven side at differential rotation cause the grooves or balls of the driving side to follow their own motion on the other output-side rotary body.
