摘要： A vehicular differential device includes a differential rotation mechanism, and a torque input member that receives drive torque, the drive torque is distributed and transmitted to a first drive shaft and a second drive shaft. The differential rotation mechanism includes an input gear that rotates as a unit with the torque input member, an output gear that rotates as a unit with the first drive shaft, a first gear and a second gear that rotate as a unit, and a carrier that supports the first gear and the second gear, the carrier being configured to rotate as a unit with the second drive shaft. The gear ratio between the input gear and the first gear is different from that between the output gear and the second gear. During differential rotation, the first drive shaft and the second drive shaft are rotated in opposite directions.

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： In a disclosed center differential, a front sun gear and a rear sun gear are received within a housing such that they are coaxial with a rotational axis of the housing. The pair of sun gears have helical teeth respectively. The helical teeth of the rear sun gear is helically twisted in a direction for generating a force for urging the rear sun gear toward a rear end wall of the housing when the vehicle makes a turn in its coast driving mode. A front friction generating mechanism is interposed between the front end wall of the housing and the front sun gear, and a rear friction generating mechanism is interposed between the rear end wall of the housing and the rear sun gear. A friction torque transmitted between the housing and the rear sun gear through the rear friction generating mechanism when the vehicle makes a turn in its coast driving mode is larger than a friction torque transmitted between the housing and the front sun gear through the front friction generating mechanism.
