摘要： A planetary differential including a differential case rotatable about an axis and a method of manufacturing thereof. The differential case includes a cover, a housing, an annulus gear, and a ring gear. The differential case defines a differential cavity having a clutch cavity and a planet cavity separated by a retainer plate coupled to the housing. The modular nature of this system allows both open and torque biasing constructions in the same packaging space. The method of manufacturing the differential includes the steps of coupling a retainer plate to the housing between the clutch cavity and the axial opening, placing a planetary gear set in the planetary cavity, and fixing the housing to the annulus gear and ring gear.

摘要： A lightweight limited slip differential for a tubular or independent axle assembly. The differential biases the torque applied to the wheels through clutch rings engaged on the pinions. The pinions include a mating surface that engage a similar profile on the clutch rings. The clutch rings may be frictionally restrained or coupled together so that the pinion movement is restrained to bias the torque between the wheels.

摘要： A direct drive differential containing a ring gear and a differential pin attached directly to the ring gear. This arrangement changes the load path through the differential case that allows for a new design to be created. The ring gear has a slot and the differential pin has a flat on the sides that mate together when assembled. The differential pin is round and the ring gear has a radius that mate together when assembled. The ring gear has a diameter machined into the inside ring diameter but allows a pin with slots to be assembled. The pin locks into place in the ring gear by rotating the pin during assembly. The ring gear has a through hole or is drilled and tapped and the differential pin has a hole therefore the two parts can be locked together in place.

摘要： A method of controlling torque transfer from a torque input source to an outlet source in which an electronically controllable magnetorheological fluid-based torque limiting device is coupled to either a differential pinion gear, a side gear, both the differential pinion gear and side gear, or both side gears of a differential assembly. By introducing current through electronically controllable magnetorheological fluid-based torque-limiting device during a turning or spin-out condition, and thereby increasing the viscosity of the magnetorheological fluid within the torque limiting device, the amount of torque that is transferred to the output source through the differential assembly can be controlled.

摘要： A circumferentially contractible clamp operated by a bolt and nut actuator wherein a U-shaped safety saddle pivotally mounted upon one end of the clamp band includes a threaded bore receiving a threaded stem of the nut threaded upon the bolt. The inner end of the stem is operatively associated with the band other end wherein rotation of the nut tensions the bolt and the interconnection of the nut stem and the saddle supports the nut such that the stem will maintain the band in a contracted condition even if the bolt fails.
