摘要： A differential for a vehicle. The differential includes a cage, which is rotatable about a first axis of rotation and has a drive interface, a first driven gear, mounted in the cage to be rotatable about the first axis of rotation, a second driven gear, mounted in the cage to be rotatable about the first axis of rotation, a compensating gear, which is mounted in the cage about a second axis of rotation extending perpendicularly to the first axis of rotation and meshes with the first and the second driven gear, a flywheel mass, coupled to the cage and locked against rotation with respect to the first axis of rotation and displaceable in a radial direction perpendicularly to the first axis of rotation, and a clutch, which, as a result of an outward movement of the flywheel mass in the radial direction, is movable into a locking state.

摘要： A differential assembly includes a differential housing, two side gears, at least one output hub, and at least one pinion gear assembly. When a torque input is provided to the first side gear, eccentric contact surfaces on the first side gear and the output hub contact under compression forces, and compression forces between the outer cylindrical surface of the first side gear and an inner cylindrical surface of the differential housing and between the outer cylindrical surface of the first output hub and the inner cylindrical surface of the differential housing cause frictional forces between the differential housing and the first side gear and between the differential housing and the first output hub to provide a torque bias to the differential assembly. In some embodiments, the differential housing includes a second output hub and eccentric contact surfaces on the second side gear and the second output hub.

摘要： The present invention relates to torque transfer and torque limiting system technology and applications. This invention relates to providing improved torque limiting systems that employ tolerance rings for controlling transmitting power between a single power-input shaft and one or more power-output shafts, which can protect mechanical equipment and drivetrains from damage by mechanical overload. Relating to motor vehicle differentials, the present invention can control differentiation between two power-output shafts, or drive shafts by providing friction internal to said differential and limit “undesirable” slip or differentiation between wheels, as might occur when one wheel encounters a low-traction condition, providing a limited-slip differential.

摘要： The drive train of a truck is modified by the addition of a single changeable pair of mating gears positioned between the output shaft of the transmission and the intermediate gear train that drives the ring/bull gear fixed to the drive-axle differential for a first set of drive wheels. One gear of this changeable pair is releasably connected to the distal end of the output shaft of the transmission, while the mating gear is releasably connected to the input of the intermediate gear train of the ring/bull gear for single drive-axle trucks or to the housing of a high-bias drive-shaft differential having co-axial output shafts for tandem drive-axle trucks. These changeable gear pairs are preferably maintained in stock in predetermined ratios so that the drive ratio of the truck can be quickly, easily, and inexpensively altered by the selection of an appropriate gear pair to accommodate different expected operating conditions.

摘要： 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.

摘要： A differential features larger amplitude in gear ratio fluctuation and higher torque bias ratio. When one of the driving wheel slips, the period of the gear ratio fluctuation between the pinion and side gears involves at least two pitches, thus each period of the gear ratio fluctuation involves a group of teeth, and the number of teeth involved in each group are corresponding to the number of pitches involved in each period. Each pinion has an odd number of groups of teeth, and the group number in side gears is a multiple of the number of pinions. The differential is particularly suitable for off-road vehicles, tippers and wheeled civil engineering machinery.
