摘要： A transmission may include an input shaft, a first output shaft, a second output shaft, a first planetary gearset, and a second planetary gearset connected to the first planetary gearset. The input shaft, the first and second output shafts, and the planetary gearsets may be arranged such that a torque input via the input shaft is converted and distributed in a defined ratio to the two output shafts, and the formation of a combined torque is prevented. At least one element of the first planetary gearset may be connected to at least one element of the second planetary gearset with a shaft for conjoint rotation, and at least one element of the second planetary gearset may be fixed in place on a non-rotating component. A connector may be arranged and configured to passively, and therefore without a control unit and without an actuator, connect the first output shaft and second output shaft.

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： The invention relates to a spur gear differential (1), in particular for motor vehicles, comprising a planet carrier (2) for circulating about a differential axis (X), a first output spur gear (3), which is arranged coaxially to the differential axis (X), a second output spur gear (4), which is likewise arranged coaxially to the differential axis (X), and at least one pair (5) of planet gears (6, 7) that mesh with one another, said pair being rotatably arranged in the planet carrier (2), each planet gear (6, 7) meshing with one output spur gear (3, 4). At least one of the output spur gears (3, 4) and/or of the planet gears (6, 7) is conically toothed in such a way that, when the planet gears (6, 7) rotate relative to one another, the at least one of the output spur gears (3, 4) and/or of the planet gears (6, 7) is moved into a position in which a blocking effect is brought about. The invention further relates to a corresponding method for producing a spur gear differential (1) of this type.

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： This differential apparatus has a differential casing rotated by an engine, side gears on an output side arranged within the differential casing and spline-connected to output shafts, pinion gears for connecting the gears, storing holes for slidably and rotatably storing the gears, a thrust block for receiving thrust forces of the output shafts, washers, respectively opposed to the gears and movably arranged with respect to the thrust block in an axial direction, and a spring for pressing the washers, against the gears, and giving frictional torque to said gears. Accordingly, no thrust forces of the output shafts are inputted to the washer members and the spring and initial torque is released from influences of the thrust forces of the output shafts so that stable differential limiting characteristics can be obtained.

摘要： The present invention relates to a limited slip differential of the general type wherein when one of the driving wheels begins to slip or loses traction driving power is transmitted to the wheel retaining traction. The unique features of this invention involve utilizing engine input torque as the force for progressively actuating a clutch to couple differential elements to direct power to a driving wheel having traction; constantly sensing the differences between the engine input torque and the resistive torques of the driving wheels; and limiting the resistive torque of the driving wheels which can act in opposition to the clutch-applying force of the engine input torque to the differential.
