A limited slip differential for vehicular applications that eliminates chattering noise from the differential while maintaining seal integrity. This is accomplished by the use of a differential casing that includes at least a pair of fluid seals isolating a first chamber for bathing the respective differential components in a fluid lubricant appropriate to the contained components. A fluid lubricant, such as one containing a friction modifier is particularly suitable for the array of friction plates and pads of a disk pack, but can be detrimental to sealing elements, such as about the pinion gear. The separate chambers allows for the use of different fluid lubricants.

Limited slip differential with self contained oil supply

In a differential/mechanism for transmitting power from a drive shaft to the axle shafts of a motor vehicle, an axle shaft end play adjuster is threadingly disposed at the end of the axle shaft adjacent the differential pinion shaft. The end play adjuster limits the range of axially inward movement of the axle shaft. A axle shaft end play adjuster assembly includes a shaft supported for rotation about a longitudinal axis having a threaded portion located near an axial end of the shaft to support a washer and a threader adjustment member threadingly engaging the end of the axle shaft adjacent the differential pinion shaft. The adjustment members threaded onto the interior axial end of the axle shaft may respectively engage the associated side gear through a splined interface.

Axle end play adjustment systems and methods

The device for adjusting an endplay of an axle shaft in a differential assembly includes an axle shaft supported in a differential case for rotation about a longitudinal axis, and an endplay adjustment member threadedly mounted on a terminal shoulder provided at an inboard end of the axle shaft. The axle shaft has external splines adapted to mate with internal splines of a differential side gear and an annular groove located adjacent to the terminal shoulder. The annular groove receives a retainer ring provided to limit an axial displacement of the axle shaft in an outboard direction. The endplay adjustment member is selectively positionable on the terminal shoulder along the axial direction of the axle shaft to variably limit an axial movement of the retainer ring within the annular groove, thus adjusting the axle shaft endplay.

Adjustable axle shaft endplay

A differential assembly having a limited slip device with a mechanism to adjust the preload of a clutch pack. The differential assembly includes a differential case with pinion and side gears disposed therein. The clutch pack is disposed between at least one of the side gears and the differential case to retard relative rotation there between. An adjustment collar is disposed between the clutch pack and the differential case to adjust the preload of the clutch pack. Elongated slots are formed through the differential case to provide external access to spanner slots formed in the adjustment collar. A tool may be inserted through the elongated slots to engage the spanner slots and selectively rotate the adjustment collar to adjust the preload.

Limited slip differential with adjustable preload

An adjustable pinion offset in a differential axle assembly. The offset between a pinion gear and shaft relative to a ring gear in the differential axle assembly is adjustable due to an eccentric mounting of the pinion assembly relative to the differential housing containing the ring gear. The pinion shaft is eccentrically mounted within a bore of the differential housing such that a simple rotation of the pinion assembly about the eccentric pilot mounting adjusts the position of the pinion shaft with respect to the ring gear to adjust pinion offset. Once properly positioned, the pinion assembly is secured to the differential housing to maintain the desired position. This invention substantially reduces the noise associated with gear offset error.

Differential axle assembly with adjustable gear offset

A differential having a housing for receiving differential components. An input shaft, for example a drive pinion gear, is rotatably mounted within the differential housing. A drive line connection point is affixed to the drive pinion gear and is the mounting point for the drive shaft. A fan is disposed on the drive line connection point and is used to force air over the differential housing. The fan may be formed integrally with a drive train part, or be separable therefrom. Rotation of the fan forces air over the surface of the differential housing causing forced convection cooling of the differential components.

Forced convection axle cooling

A container/dispenser is described for carrying and dispensing heavy electrical cable of the plastic or rubber-coated variety that is used in wiring homes and businesses. The container has unitary construction and is fabricated from a strong but flexible material, such as nylon, sailcloth, etc. A closeable opening is provided in one end for the insertion of a coil of electrical cable, and a central exit opening is provided for extruding cable from the center of the coil. A detachable and adjustable strap is included for carrying the container/dispenser. In operation, a preformed coil of electrical cable is inserted through the opening into the container/dispenser and is strand-wise extruded from the central exit opening. The opening through which the coil is placed in the container/dispenser can be closed, by means such as velcro fasteners.
