摘要： A system and method for monitoring a service life of lubricant that is applied to vehicle components is disclosed. The method includes receiving at least one input parameter. The input parameter relates to the vehicle's operation. The method also includes determining a remaining service life of a lubricant. The lubricant is applied to a driveline component of the vehicle. The determination of the remaining service life of the lubricant is based on the receiving of at least one input parameter.

摘要： A helical LSD includes a case defining an inner cavity and a plurality of grooves disposed around the inner cavity. In addition to the case, the helical LSD includes a plurality of pinion gears. Each pinion gear is disposed in one of the grooves and includes a plurality of gear teeth. Each gear tooth has a top land. The helical LSD further includes at least one helical output gear disposed in the inner cavity of the case. The helical output gear meshes with the pinion gears, and the pinion gears are disposed around the helical output gear. The top land has a surface profile characterized by raised portions and indentations in order to minimize noise and vibration when the pinion gears rotate relative to the case. The surface profile can also be applied to contact surfaces of power transfer units and transfer cases.
摘要翻译： 螺旋LSD包括限定内腔的壳体和设置在内腔周围的多个槽。 除了这种情况，螺旋LSD包括多个小齿轮。 每个小齿轮设置在一个凹槽中并且包括多个齿轮齿。 每个齿轮齿有一个顶部的土地。 螺旋LSD还包括设置在壳体的内腔中的至少一个螺旋输出齿轮。 螺旋输出齿轮与小齿轮啮合，小齿轮围绕螺旋输出齿轮设置。 顶面具有以凸起部分和凹陷为特征的表面轮廓，以便当小齿轮相对于壳体旋转时使噪音和振动最小化。 表面轮廓也可以应用于动力传递单元和传送箱的接触表面。

摘要： A vehicle, a prop-shaft and a method of reducing noise in a vehicle are provided. The prop-shaft includes a cylindrical shaft having a hollow interior. A liner is positioned within at least a portion of the hollow interior. A first retaining member is disposed adjacent an end of the liner, the first retaining member sized to inhibit movement of the liner in a first direction. A second retaining member is disposed adjacent an opposite end of the liner from the first retaining member, the second retaining member sized to inhibit movement of the liner in a second direction, the second direction being opposite the first direction.
