摘要： A method and system of improving shift event performance in a vehicle with an automatic transmission. One or more accelerometers in the vehicle are used to sense one or more longitudinal acceleration values. The longitudinal acceleration values or values derived therefrom are compared with predetermined stored values. Shift event behavior is changed in response to differences between the one or more longitudinal acceleration values or values derived therefrom and the predetermined stored values.

摘要： A clutch (A,B) includes a cam (20,70) and a rotor (22,74), both of which revolve around a common axis (X). The cam has a camming surface (30,72) provided with lobes (32), whereas the rotor carries pistons (26,80) which bear against the camming surface of the cam. The pistons project from piston cavities (40,42; 76) in the rotor and those cavities communicate through a connecting cavity (44,78), to thereby form a fluid chamber (56,82) of constant volume which contains a magneto-rheological fluid (28,84). An electrical coil controls the viscosity of the rheological fluid. When the viscosity is low, the pistons will move inwardly and outwardly on the rotor as the camming surface passes over them and no torque will transfer between the cam and rotor. However, when the fluid is viscous, the fluid will impede displacement of the pistons in the piston cavities, and the pistons will grip the camming surface sufficiently to enable torque to transfer between the cam and rotor.

摘要翻译： 离合器（A，B）包括凸轮（20,70）和转子（22,74），两者都围绕公共轴线（X）旋转。 凸轮具有设置有凸角（32）的凸轮表面（30,72），而转子承载抵靠凸轮的凸轮表面的活塞（26,80）。 活塞从转子中的活塞腔（40,42; 76）突出，并且这些空腔通过连接空腔（44,78）连通，从而形成恒定体积的流体室（56,82），其包含磁流变学 流体（28,84）。 电线圈控制流变液的粘度。 当粘度低时，当凸轮表面越过它们时，活塞将在转子上向内和向外移动，并且转矩将不会在凸轮和转子之间传递。 然而，当流体是粘性的时，流体将阻止活塞在活塞空腔中的位移，并且活塞将充分地夹紧凸轮表面，以使转矩能够在凸轮和转子之间传递。

摘要： A shaft rotates within a housing on a double row tapered roller bearing and remains extremely stable at all temperatures, even though the housing is formed from a light weight metal having a significantly greater coefficient of thermal expansion than the metal of the bearing. To this end, the housing contains a bore defined by a cylindrical surface and a conical surface which flares away from the cylindrical surface and opens out of one face of the housing. The bearing has two cones which surround the shaft, a unitary or double cup which fits into the bore of the housing, and tapered rollers arranged in two rows between the cones and cup. The double cup on its exterior has a cylindrical surface which fits into the cylindrical surface of the housing bore and a flange provided with a beveled face which is against the conical surface of the housing bore. In addition, the cup has a threaded end which projects axially beyond the cylindrical surface of the cup engages a nut that is on the housing at the end of the cylindrical surface of the bore. The nut draws the beveled surface of the cup flange tightly against the conical surface of the housing bore. With an elevation in temperature, the housing expands axially and causes the flange to seat even more tightly against the conical surface of the housing, so that the cup remains firmly positioned, both radially and axially, in the housing, even though the cylindrical surface of the housing bore enlarges with respect to the cylindrical surface on the housing.

摘要： A vehicle drive system capable of selectively providing all-wheel drive and single-driven-axle modes includes a front drive unit having a planetary gearset with a grounded ring gear and a sun gear driven by the transaxle's drive spool via an input shaft, and a differential selectively coupled by a dog clutch to one of the sun gear or the planetary carrier, or neither of them, to thereby selectively provide both an available low range and a front axle disconnect. The front drive unit further defines a power take-off unit with a clutch selectively coupling the input shaft to a propshaft. The rear drive unit includes a planetary gearset with a grounded ring gear, a sun gear driven by the propshaft, and a differential selectively coupled by a dog clutch to one of the sun gear or the planetary carrier, or neither of them, to thereby likewise selectively provide both an available low range and a rear axle disconnect.

摘要： A roller bearing for use in transmission cases (1) made from aluminum alloy or other lightweight materials where the transmission contains a steel shaft (2) which is supported in the case on two directly mounted tapered roller bearings (8,9) so that the two bearings (8,9) confine the shaft (2) both radially and axially. To compensate for the differences in expansion and contraction between the case and the steel shaft (2) as the transmission or transaxle experiences variations in temperature, a race (20) of at least one of the bearings is fitted with a compensating ring (34) having a coefficient of thermal expansion greater than that of the case (1) or shaft (2). As a consequence, the bearings operate at a generally uniform setting over a wide range of temperature variations.
