Abstract: In at least some implementations, a differential for a vehicle includes a pinion gear, a pair of side gears and a housing. The side gears are meshed with the pinion gear and the housing defines a cavity in which the pinion gear and side gears are received. The housing also has an opening with an inner end leading to the cavity and an outer end spaced from the inner end. The opening is adapted to receive a shaft therethrough for coupling of the shaft to one of the side gears and the opening is defined at least in part by a journal surface. The journal surface is concave with respect to the shaft and provides a converging portion from the inner end to a central portion between the inner end and outer end and a diverging portion from the central portion to the outer end.

Abstract: The invention relates to a drive device for motor vehicles with at least one longitudinal output or transverse output differential gear, with an input shaft, and with a means for controlled torque distribution to the two output shafts. A quick-response, structurally advantageous drive device is thus achieved in that the differential gear is a self-locking differential gear and in that a speed-regulation drive, which changes the differential-side speed of 1:1 in the plus or minus direction based on dynamic performance parameters, is integrated into one of the output shafts, or in that speed-regulation drives, which alternately change the differential-side speed of 1:1 in the plus direction or in the negative direction based on dynamic performance parameters, are integrated into two output shafts.

Abstract: The various embodiments disclosed and pictured herein are directed to an epicyclic joint with at least one axis of rotation. The epicyclic joint includes rotational members mounted to frame members in such a manner that rotational energy may be transposed along multiple axes of rotation without the need for the frame members to rotate. Epicyclic gear sets and compensation gears and shafts are employed to mitigate vibration, stress, and perturbation of the rotating members when the orientation of the epicyclic joint is varied along any of the axes of rotation. Planetary gear sets or differential gear sets may be used with the epicyclic joint, as may spur gears and miter gears.

Abstract: An inter-axle differential assembly includes a forward side gear and a rear side gear that are supported by an input shaft. The forward and rear side gears are in meshing engagement with a plurality of inter-axle differential pinion gears that are supported on a spider. The spider is driven by the input shaft and has a plurality of legs with each leg supporting one of the plurality of inter-axle differential pinion gears. A helical drive gear is fixed for rotation with the forward side gear. The helical drive gear includes a center cavity defined by a spherical inner surface. The spider and the plurality of inter-axle differential pinion gears are positioned within the center cavity. This eliminates the need for an inter-axle differential housing assembly and reduces standout.

Abstract: A differential drive having a drive housing in which a differential carrier (14) is rotatably supported around its longitudinal axis (A). The drive has sideshaft gears (18, 19) which are supported so as to be rotatable relative to the differential carrier (14) around the axis (A), and differential gears (22) which are supported in the differential carrier rotatably around axes (R) extending radially relative to the longitudinal axis (A), which engage the sideshaft gears (18, 19) and which rotate together with the differential carrier (14). The differential carrier (14) forms journals (16, 17) which extend co-axially relative to the longitudinal axis (A) and by means of which the differential carrier (14) is rotatably supported in the sideshaft gears (18, 19) and wherein the sideshaft gears (18, 19), in turn, are rotatably supported in the drive housing.

The viscous transmission also connects the output of the first side shaft to one of the side shaft gears.

Abstract: A improved differential design intended for use in a vehicle, such as a tractor using a hydrostatic transmission. The differential has a ring gear with an opening formed therein. A pair of axle shafts used to drive the vehicle engage respective bevel gears, which are also engaged to a pair of planet gears in the differential. The planet gears are rotatably mounted in the ring gear opening and may be mounted on a shaft. The differential includes a block having at least a first end and a second end which engage the ring gear opening, and the block has a longitudinal axis which is not coincident with the axis of rotation of the planet gear. The block thus increases the strength of the ring gear and allows use of a ring gear having a larger opening.

Abstract: A switchable differential drive, preferably for a vehicle driven by an electric motor, has a differential drive housing, a drivable differential carrier rotatably supported in the housing, two axle shaft gears supported therein, which are connected to output shafts extending out of the differential carrier and which are connected to one another via differential gears. A first output shaft is designed directly as an axle shaft and a second output shaft is coaxially supported in the first axle shaft. Two switching couplings are arranged coaxially relative to the latter axle shaft. To obtain a first gear stage, the first switching coupling is engaged, thereby non-rotatingly connecting the output shaft to the axle shaft, while the second switching coupling is open. To obtain a second gear stage with one wheel drive, the second switching coupling is engaged, thereby non-rotatingly connecting the output shaft to the differential drive housing while the other switching coupling is open.

Abstract: A rotation transmitting device having an outer ring formed with a bore, a holder fixedly mounted in the bore and rolling elements mounted in the holder so as to be rollable as the outer ring rotates. A pair of input shafts are provided coaxially with an axis of rotation of the outer ring so as to sandwich the rolling elements from both sides thereof. Output shafts are rotatably mounted in the bore at both sides of the input shafts. Cages are rotatably mounted between the output shafts and the outer ring and formed with pockets. Engaging elements are mounted in the pockets and adapted to be engageable between opposite surfaces of the outer ring and the output shafts with relative rotation between the cages and the output shafts in either direction. Elastic members are mounted in the pockets to keep the engaging elements in a position where they are not engaged.

Abstract: The driving gear meshes with the gear on the web of a planetary gear. This planetary gear includes an arrestable sun wheel. The output sun wheel is rigidly connected to the drive shaft. It extends through a sleeve section of the web. A longitudinally displaceable shifting sleeve is located on the sleeve section, which shifting sleeve has a plurality of control disks. These control disks control via a roller the rocking movement of the upper feeding roller. Accordingly, the period of the rocking movement can be selected depending on a respective selected control disk. If the sun wheel is unlocked, the shifting sleeve may be moved such that it engages directly the drive shaft such that by properly selecting the number of teeth it is possible to choose between a rotational speed transmission relation of 1:2 and 1:1.
