摘要： A rigid drive axle assembly includes a support beam member having a substantially flat central plate section, a differential assembly module secured to the central plate section through at least two threaded studs extending from the central plate section. The differential assembly module includes a differential carrier frame member having two bearing hubs receiving differential bearings. A method for verifying a predetermined bearing preload of the differential assembly module comprises the steps of preloading the differential bearings to the predetermined bearing preload, inserting mounting bores in the bearing hubs of the frame member onto the mounting studs, and determining that the differential bearings are properly preloaded if the mounting studs are received in the mounting bores in the differential carrier frame member without substantial resistance, or determining that the differential bearings are not properly preloaded if the mounting studs may not be received in the mounting bores easily.

摘要： A pressure relief check valve for a hydraulically actuated clutch pack or limited slip device in a limited slip differential or torque coupling device. A ball seat is formed on the external surface of the differential case and is connected to a passageway leading to a limited slip device within the differential case to establish fluid communication there between. A ball rests on the valve seat and is retained thereon by a retainer and spring. The retainer is removable secured to the outer surface of the differential case and a coil spring is disposed between the ball and the retainer to bias the ball against the valve seat. When pressure within the differential case or limited slip device exceeds a predetermined pressure, the ball is lifted from the valve seat and fluid passes through the differential case to an exterior within the differential housing. When pressure in the differential case and limited slip device is less than the predetermined pressure, fluid is prevented from passing through the valve.

摘要： This transmnission differential of the type comprising a two-piece differential case defined by a cup-shaped case member and a side member integrally formed with a ring gear to thereby increase the strength of the ring gear and case. The side member is bolted onto the cup-shaped case member. The pinion gears of this invention are not formed with a spherical portion at its interface with the case because the present invention provides a novel design that does not require the spherical radii because the two-piece case can easily be assembled with resort to these additional machining requirements. The pinion shaft is secured against rotation by a pin trapped in a bore formed in the case when the ring gear side member is mounted to the cup-shaped case member. Because the cup-shaped case member is formed with a flat mating surface, the present invention does not require eyebrows formed into the case for drilling points where the bolt is received in the case. The two-piece design also eliminates the need for windows in the case. Therefore, the present invention reduced manufacturing costs while providing a stronger differential case.
摘要翻译：该类型包括由杯形壳体构件和与齿圈一体形成的侧构件限定的两件式差速器壳体，从而增加了齿圈和壳体的强度。侧部件螺栓固定在杯形壳体上。本发明的小齿轮在其与壳体的界面处不形成球形部分，因为本发明提供了一种新颖的设计，其不需要球形半径，因为两件式壳体可以容易地组装起来，借助于这些附加加工要求。当齿圈侧构件安装到杯形壳体构件时，小齿轮轴被被捕获在壳体中形成的孔中的销固定而抵抗旋转。由于杯形壳体构件形成有平坦的配合表面，因此本发明不需要在壳体中形成用于在壳体中容纳螺栓的钻孔点的情况下的眉毛。两件式设计也不需要窗户。因此，本发明降低制造成本，同时提供更强的差分情况。

摘要： An axle assembly employs a simple adjustable connection between the differential case and the housing to adjust the position of the ring gear relative to the pinion gear. A pair of adjustment collars facilitates positioning the differential case to selectively position the ring gear relative to the pinion gear of an input shaft. The adjustment collars threadingly engage the differential case. Bearings are disposed between the adjustment collars and the housing. The adjustment collars are rotated to position the differential case together with the ring gear. The adjustment collars are also provided to adjust the preload of the bearings. A locking collar is employed to lock the adjustment collars once the differential case and ring gear are properly positioned. In an alternate embodiment a single adjustment collar is employed. Shims and spacers are utilized to position the differential case and ring gear and the adjustment collar used to adjust the preload of the bearings.

摘要： 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.

摘要： 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.
