摘要： An apparatus and method for demagnetizing a differential (212) which has a controllable electromagnetically actuated clutch (101). The apparatus includes sensors and a coil (220) connected to a control module. The sensors receive vehicle inputs to indicate various measured values such as vehicle speed, brake pressure, magnetization current provided to the differential (212), and the like and generates signals which are transmitted to the control module. The control module initiates a demagnetization cycle when certain conditions have been satisfied as indicated by the input signals. The control module provides a DC voltage to the coil (220) to generate magnetic flux for demagnetizing the differential (212) and the components of the differential. In one embodiment a single coil is provided to which is applied both magnetization and demagnetization current. In another embodiment two coils (218, 220) are provided, one (218) for generating magnetization flux and the other (220) for generating demagnetization flux. The control alternatively applies voltages of reverse polarity in decreasing amplitudes for predetermined periods of time during a demagnetization cycle.

摘要： A differential assembly (20) including a rotatable casing (22) having an axis of rotation (23), a selectively energized electromagnet (44) proximal the casing, and a rotatable first clutch (54) disposed within the casing, the first clutch placed in operative engagement with the casing in response to the electromagnet being energized. Relative rotation between the first clutch and the casing is slowed by their being in operative engagement. A rotatable clutch hub (70) and a second clutch (76, 78) are disposed within the casing, and the casing and the clutch hub are rotatably coupled through engagement of the second clutch, which is operatively engaged in response to relative rotation between the first clutch and the casing being slowed. At least one rotatable pinion gear (106) is disposed within the casing and revolves about the axis of rotation. At least one side gear (94, 96) engaged with the pinion gear and rotatable about the axis of rotation is disposed within the casing, and is rotatably coupled to the casing through the second clutch during engagement of the second clutch. Neither of the first clutch and the second clutch is appreciably engaged with the casing in response to gear separating forces exerted between the pinion gear and the side gear.

摘要： A drive unit disconnect mechanism is operable to transmit or disconnect power from a vehicle power source to a driven unit, and can be disengaged by multiple methods depending on how much force is required to separate the internal components of the mechanism. In a first, relatively quicker method, a handle is pulled axially away from the hub to withdraw and internal gear from splined engagement with a corresponding driven gear. In a second, relatively slower method, the handle is rotated to threadably withdraw the entire disconnect mechanism from the hub, which in turn withdraws the internal gear from splined engagement with the driven gear. The quicker method is desirable in most instances, but the slower method allows disconnection of the driven unit from the vehicle power source when gear pressure prevents or impedes the quicker method.

摘要： Structural arrangements of wheel drive components facilitate the use of robust main roller bearings that are widely spaced apart from one another. This wide spacing minimizes the torque borne by the bearings for a given external load, because at least one bearing is placed closer to the expected load application point (e.g., the center of gravity of the wheel attached to the wheel hub of the drive unit). The present wheel drive bearings can support a heavy external load without expanding the overall size and configuration of a given wheel drive application.
摘要翻译：轮驱动部件的结构布置有助于使用彼此间隔很大的坚固的主滚柱轴承。由于至少一个轴承放置在预期的载荷施加点附近（例如，附接到驱动单元的轮毂上的车轮的重心），该宽间距使得由轴承承受的用于给定外部载荷的扭矩最小化，。目前的四轮驱动轴承可以支撑沉重的外部载荷而不会扩大给定车轮驱动应用的整体尺寸和结构。

摘要： A selectively locked differential has a locked configuration in which both side gears are independently locked to the differential casing so that torque is not transmitted through the pinion gears. The locking of the side gears is accomplished by generally cylindrical, ring-shaped structures with castellations on one axial end surface of each structure. These castellations selectively interfit with rotatably fixed castellations of secondary structures fixed to the differential casing, such that the ring-shaped structures define a mechanically interconnected, zero-slip arrangement with respect to the rotationally fixed secondary structures when the differential is in the locked configuration.
