    Abstract: An electric machine and differential gear assembly for providing power to a vehicle is disposed within a housing structure. The electric machine has a stator portion, and a rotor portion disposed radially inward of the stator portion and spaced therefrom by an air gap. The differential gear assembly includes a rotatable tubular housing that contains a first bevel output gear, a second bevel output gear, and two idler bevel gears. The first bevel output gear is rigidly connected to one end of a first axle, and the second bevel output gear is rigidly connected to one end of a second axle. The end portion of the first axle is supported by the housing structure via a set of bearings. The idler bevel gears are rotatably mounted on respective shafts that are each connected to the housing. The housing is rotatably supported by the housing structure via a set of bearings.

    Abstract: An improved differential incorporates gear teeth profiles which result in a force on the differential pinion gears directed radially inwardly. Thus, the gears are forced onto the differential spider, and need not be supported in the differential case. The invention thus allows the elimination of the differential case.

    Abstract: A vehicle, such as a lawn mower or garden tractor, includes an engine attached to a frame. The frame includes several wheels including two driven wheels. A first axle shaft is attached to the first driven wheel. A second axle shaft attached to the second driven wheel. The vehicle has a transmission for transmitting power from the engine to the first axle shaft and the second axle shaft for driving the first and second wheels. The transmission includes a differential for accommodating different lengths of travel between said first wheel and said second wheel, such as when the vehicle makes a turn. The differential includes a ring gear supported by the first axle shaft and the second axle shaft. A first planet gear is supported on the first planet shaft. The first planet shaft is attached to the ring gear. Similarly, a second planet gear supported on a second planet shaft. The second planet shaft is also attached to the ring gear.

    Abstract: A differential gear assembly particularly for motor vehicles having a rotatably supported differential housing, a driving gear attached to the differential housing, at least two rotatably supported differential bevel gears and a pair of output bevel gears which engage into the differential bevel gears with a constant velocity universal joint being integrated into each of the output bevel gears. The differential bevel gears are connected in a form-fitting manner to the driving gear by means of radial and/or axial recesses, apertures or the like, with the differential housing, which may be formed of two parts, being connected to the driving gear. The differential housing is formed with an aperture or is divided in the region of each differential bevel gear to form a compact structure.

    Abstract: The present application discloses structure which produces area contact in place of point or line contact between a cylindrical shaft and a cylindrical bore. When the area of contact is increased, the unit pressure is reduced which results in less wear and longer life. The combination of the present invention includes a shaft having an external surface and a member in the nature of a gear or the like which has a bore surrounding the shaft and which bore includes an internal surface. The present invention involves the situation wherein one of the shaft and member is fixed and the other of the shaft and member is rotatable. The improvement of the present invention involves the situation wherein the surface of the rotatable one of the two above mentioned members is provided with a first cooperating surface portion which has a constant radius and which extends through an angle 360.degree.. The surface of the fixed one of the members comprises a second cooperating surface portion which has a radius which matches the constant radius of the rotatable member which extends through 360.degree.; however, the second cooperating surface portion extends through an angle of less than 180.degree.. The first and second cooperating surface portions normally, although not necessarily, are axially coextensive. The surface of the fixed one of the members, in addition to the second cooperating surface portion, has an additional surface portion which has a dimension which may broadly referred to as a radius dimension, which is different than that of the radius of the first and second cooperating surface portions. In the case of a fixed shaft, which has the less than 180.degree. surface portion thereon, this additional surface portion has a radius which is smaller and in the case of a fixed member which has a bore therein which carries the less than 180.degree. surface portion, this additional surface has a radius which is larger than the radius of the surface which extends through an angle of less than 180.degree.. The present disclosure illustrates the present invention as applied to a fixed shaft supporting a rotatable gear, sprocket, pulley or any other method of power of transmission, wherein the load direction is constant to the shaft and the disclosure, also, illustrates the situation where the load direction remains constant to the bearing in the case of a rotating shaft supported by bearings. Additionally, the present invention discloses the invention as used in land vehicle differentials.
