Abstract: A shaft (4) rotates in a housing (2) on two single row tapered roller bearings (12, 14) mounted in opposition such that the raceways (30, 36) of the one bearing taper downwardly toward the raceways (30, 36) of the other bearing. The metal from which the housing is formed has a higher coefficient of thermal expansion than the metal from which the shaft and bearings are formed. The bearings are set to preload to stabilize the axis of rotation. To prevent the cups (22) (outer races) of the bearings from becoming loose as a consequence of differential thermal expansion between the housing and shaft, the cups are provided with beveled back faces (42) which abut beveled shoulders (58) at the ends of bearing seats (52, 54) in the housing. As the housing expands radially and perhaps eliminates radial interference fits between the cups and housing, the housing also expands axially and maintains the beveled shoulders of the bearing seats firmly abutted against the beveled back faces of the cups, so that the cups do not displace either axially or radially.

Abstract: A stabilizer bar (D) for controlling the roll of an automotive vehicle has left and right sections (16,18), each provided with a torsion rod (24) and a torque arm (26). The torsion rods are aligned along a transverse axis (X) and attached to a structural component (B) of the vehicle, while the torque arms are connected to the left and right control arms (2) of the vehicle's suspension system (A). In addition, the bar has a coupling (20) between the torsion rods of the two sections and a valve (22) connected to the coupling, all for controlling the torsional stiffness of the bar. When one torsion rod rotates relative to the other out of a neutral position, a piston (40) within the coupling displaces a magneto-rheological fluid from the coupling. Within the valve are a restrictor (98) and a coil (104) at the restrictor for controlling the viscosity of the fluid there, and this determines the rate at which the fluid is displaced from the cavity, which in turn determines the force required to move the piston and ultimately the torsional stiffness of the stabilizer bar.

Abstract: 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.

The first tapered roller bearing (B) incorporates a continuous seal (4) and o-ring (9), with the first tapered roller bearing (B) either mounted to the differential gear mechanism case by retaining a mounting flange (7) on the bearing cup (5), or threaded into the differential gear mechanism case by threads (41) on the exterior of the bearing cup (40).

Abstract: 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.

Abstract: A transfer case (12, 90, 130), which may be used to distribute the torque selectively between the primary and secondary driving wheels (2, 4) of an automotive vehicle (A, B), includes an input element (30, 104, 132) and two output elements (32, 34; 106, 108; 132, 134) located along a common axis (X). It also includes a magnetic particle clutch (38, 102, 138) and a planetary gear set (36, 100, 140) which are both organized by about the same axis. The clutch and planetary set are connected together such that they provide a direct path through which torque is transferred from the input element to one of the output elements without slippage. The arrangement further provides a slip path through which torque is transferred from the input element to the other output element with slippage, and this path has two segments, one through the planetary set and the other through the clutch and planetary set. The clutch path accommodates slippage and the proportion of torque transferred through the slip path depends solely on the electric current conducted through the clutch.

Abstract: An electric drive axle (B,C), which is located between and powers the left and right drive wheels (2,4) of an automotive vehicle (A), includes an electric motor (22,84) and left and right torque couplings (24,26). Torque developed by the motor transfers through the torque couplings to axle shafts (10,12) which are connected to the drive wheels. Each torque coupling includes a magnetic particle clutch (42) and a planetary set (44) organized such that the current flowing through the electromagnet of the clutch controls the torque delivered through the coupling. The magnetic particle clutches also accommodate slippage so that the drive wheels may rotate at different angular velocities.

Abstract: A shaft (S) rotates within a housing (H, J) on a double row tapered roller bearing (B, C) 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 (16, 100) defined by a cylindrical surface (18, 102) and a conical surface (20, 104) which flares away from the cylindrical surface and opens out of one face of the housing. The bearing has two cones (30, 32) which surround the shaft, a unitary or double cup (34, 116) which fits into the bore of the housing, and tapered rollers (36) arranged in two rows between the cones and cup. The double cup on its exterior has a cylindrical surface (58, 118) which fits into the cylindrical surface of the housing bore and a flange (60, 120) provided with a beveled face (64, 124) which is against the conical surface of the housing bore. In addition, the cup has a threaded end (62, 122) which projects axially beyond the cylindrical surface of the cup engages a nut (66, 106) 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.
