摘要： A plural output differential drive system provides plural outputs that are differentially related to each other. Four or more output shafts are driven from a single input shaft, each output shaft being differentially linked with the other output shafts. The entire differential drive arrangement may be expanded to any number of outputs, and is contained within a single housing. The output shafts of the plural output differential will transfer power in applications wherein a predetermined distribution of torque is required at four or more outputs, irrespective of their speeds. All the outputs are coupled as a series of all epicyclic differentiating mechanisms, or a series of epicyclic and bevel differentiating mechanisms. N outputs are achieved by introducing multiple epicyclic gear mechanisms. The input shaft may be arranged to be coaxial with the output shafts, or may be at any other angle, including orthogonal thereto. Typical applications include powering four or more live axles on vehicles, providing rotary power for developing equal or predeterminably proportional torques for simultaneously tightening multiple bolts, and generating equal forces on the gripper fingers of robotic hands. In addition, the outputs can be applied to leveling devices where four or more legs must apply equal pressures on a surface.
摘要翻译： 多输出差分驱动系统提供彼此差异相关的多个输出。 四个或更多个输出轴由单个输入轴驱动，每个输出轴与其他输出轴差分连接。 整个差分驱动装置可以扩展到任何数量的输出，并且被包含在单个壳体内。 多个输出差速器的输出轴将在其中在四个或更多个输出处需要预定的转矩分布的应用中传递功率，而与其速度无关。 所有的输出耦合为一系列所有行星差速机构，或一系列行星和斜面差速机构。 通过引入多个行星齿轮机构来实现N个输出。 输入轴可以布置为与输出轴同轴，或者可以处于与其正交的任何其它角度。 典型的应用包括为车辆上的四个或更多的活轴提供动力，提供旋转动力，用于形成相等或可预定比例的扭矩，以同时收紧多个螺栓，并在机器手的手指上产生相等的力。 此外，输出可以应用于其中四个或更多个腿必须在表面上施加相等压力的调平装置。

摘要： A planetary transmission for selectively shifting among three forward and one reverse speeds includes first and second sun gears respectively secured to and clutchable to a drive shaft to provide a first forward speed. A planet carrier, secured to a driven shaft, surrounds the sun gears and carries a first planet gear meshing with the first sun gear and a compound planet gear comprising a second planet gear meshing with the first planet gear and a third planet gear meshing with the second sun gear. Respectively concentric with the first and second sun gears are brake-associated first and second ring gears which respectively mesh with the first and third planet gears. First, second, and third brakes are respectively connected to the first ring gear, the second ring gear, and the first sun gear to stop and allow rotation of said gears to provide two forward and one reverse speeds; a third forward speed is provided by clutching the second sun gear to the drive shaft.

摘要： A multi-speed clutch-damper assembly for selectively connecting an output of a power-source to an input of a transmission includes a planetary gear-set. The planetary gear-set is encased in a housing and configured to provide two selectable speed ratios and a damper between the power-source output and the transmission input. The planetary gear-set includes first, second, and third gear members. The second gear member is configured to be connected to the transmission input and the third gear member is configured to be selectively fixed to the housing. The planetary gear-set also includes an elastic element operatively connected to the second gear member and configured to generate torsional vibration damping between the output of the power-source and the input of the transmission. The clutch-damper assembly also includes a first clutch configured to selectively connect the power-source output to the first gear member for transmitting torque of the power-source to the transmission.

摘要： A variable state planetary shifting transmission can include an input shaft, an output shaft; and a planetary system having a sun gear associated with the input shaft, a planetary carrier, and a ring gear associated with a ring housing. The transmission can include an overrunning clutch operably coupled to the planetary carrier. The transmission can include a clutch assembly coupled to the planetary carrier. The transmission is capable of changing the speed ratio between the input shaft and the output shaft by selective engagement of the clutch assembly against the ring gear which can cause either the freeing or locking of the planetary carrier by the overrunning clutch.

摘要： A transmission comprising an input shaft connectable to a power generation device such that the input shaft is rotatable at a power input rotational speed, an output shaft connectable to a driveline of the vehicle, and a plurality of gear sets selectable to operably connect the input shaft to the output shaft providing a rotational speed reduction ratio therebetween. The gear sets comprise a master active gear set having a master gear ratio, a slave active gear set having a slave gear ratio, and a passive gear set having a passive gear ratio. The passive gear set is operable to selectively engage the master and slave active gear sets to provide the high numeric compound ratio rotational speed reduction that is the product of the master active gear ratio, the slave active gear ratio and the passive gear ratio.
