A vehicle driveline component with a housing, a ring gear of a transmission, and a plurality of spring sets. The housing defines a bore and a plurality of grooves that are spaced circumferentially about the bore. The ring gear includes an internally-toothed ring gear body and a plurality of mounting teeth that project radially from the ring gear body. The first mounting teeth are received into the grooves in the housing. Each of the spring sets has a first spring, which is disposed between a first side of an associated one of the mounting teeth and a first wall of an associated one of the grooves into which the associated one of the mounting teeth is received, and a second spring that is disposed between a second side of the associated one of the mounting teeth and a second wall of the associated one of the grooves.

A driveline component with a shaft, a friction clutch and a centrifugal valve. The shaft has a supply passage and a feed passage that intersects the supply passage. The centrifugal valve has a valve seat, which is formed on the shaft and intersects the feed passage, a valve element and a flyweight that is pivotally coupled to the shaft. The valve element is received in the valve seat and is movable between a first position, in which the valve element is abutted against the valve seat, and a second position in which the valve element is displaced from the valve seat. The flyweight has a weight and a cam and is configured so that radially outward rotation of the weight in response to centrifugal force causes the cam to drive the valve element toward the first position.

A variable spring rate absorber is adjusted to provide the vibration attenuation characteristics needed to match current operating conditions. Control of a variable spring rate absorber determines the desired absorber spring rate for existing conditions based on a number of inputs and predetermined characterization tables. Once the spring rate is calculated, a predetermined map may be used to determine the absorber setting needed to achieve the desired spring rate. A sensor may be used to measure the actual state of the absorber to determine the extent to which the setting must be adjusted to achieve the desired spring rate.

A number of variations may include a transmission housing for a transmission with a flexible drive having a housing section with at least one curved wall surface () facing an accommodation space for a wheel of the flexible drive, wherein the wall surface can be changed in a radial direction, thereby offsetting and/or enlarging the accommodation space. A number of variations may include a transmission and to a method for producing transmissions.

A multi-mode clutch module includes first and second races, and a plurality of race engagement mechanisms situated between the races. The module incorporates an actuator sleeve having an axially acting actuator cam finger. The cam finger is configured with variable radial thicknesses to provide a plurality of predetermined fixed positions for contacting the race engagement mechanisms to cause the engagement mechanisms to selectively interact with the races. The actuator sleeve is thus adapted to control axial movement of the actuator cam finger between at least two axially spaced positions in one embodiment. In other embodiments within the scope of this disclosure, the actuator cam finger may be adapted to move axially among any number of predetermined positions to operatively permit or prevent transmittal of torque between the first and second races, irrespective of the relative rotational direction of the races.

A power transfer system () for a vehicle to be driven by a prime mover through a first input drive shaft () and an electric motor through a second input drive shaft () carried by the vehicle. A power transfer system () supports the first and second input drive shafts () to be mechanically interconnected to an output drive shaft () for driving driven wheels of the vehicle. A clutch () engages () and disengages () the first input drive shaft () with respect to the output drive shaft (). A first output drive sprocket () is connected to the output drive shaft (), a second output drive sprocket () is connected to the second input drive shaft (), and an endless loop sprocket-engaging drive member () extends between the first and second sprockets (). A disconnect mechanism () engages () and disengages () the second input drive shaft () with respect to the output drive shaft (). The disconnect mechanism () is located between one of the sprockets () and its corresponding drive shaft ().

A driveline product including first and second inputs having input rotational axes, first and second outputs having output rotational axes, a transfer coupling between at least one of the input rotational axes and at least one of the output rotational axes, and at least two selective couplings operatively coupled between the inputs and the outputs for operation selective between at least two drives powered by at least one of two prime movers.

An auxiliary electric drive assembly includes an alternating current induction motor, planetary speed reduction gearing and a differential. The differential may be either active or passive. The auxiliary drive system is utilized as the front axle in a rear wheel drive vehicle and the rear axle in a front wheel drive vehicle. Elimination of many of the components in a conventional four wheel drive system such as the transfer case and hybrid gears improves the overall efficiency and fuel economy of a vehicle so equipped.

An anti-shudder constant velocity universal joint of the tripod type is provided having an outer joint member including three circumferentially distributed, axially extending longitudinal tracks formed therein, and an inner joint member having three circumferentially distributed radial journals arranged to engage the longitudinal tracks when the joint is assembled. The end of each journal is mated with and supports rotation of a roller bearing assembly, while rotating and pivoting within the roller bearing assembly upon articulation of the joint. This reduces the frictional forces on the roller bearings created by maintaining the roller bearings in a relatively proper/parallel orientation within the tracks by allowing the journal ends to freely rotate and pivot therein. A spherical-to-spherical contact surface is provided between the journal ends and an inner ring of the respective roller bearing assemblies to lower Hertzian stresses by distributing forces over a larger region of contact.
