A damper assembly for absorbing and attenuating torsionals and vibrations transmitted from an engine to a transmission is provided. The damper assembly includes a damper flange with a plurality of spring-mass damper systems operatively attached thereto and elongated circumferentially about its outer periphery. Each spring-mass damper systems include an inner spring nestably positioned inside an outer spring, a first spring retainer having a base portion defining a first interface surface with a first pilot portion extending therefrom to define a second interface surface with a second pilot portion extending therefrom, and a second spring retainer having a base portion defining an interface surface with a pilot portion extending therefrom to define a fourth interface surface. The first and third pilot portions engage with and thereby restrict axial and radial movement of the outer spring. The second pilot portion is attached to the inner spring thereby restricting relative movement therebetween.

An internal gear and cap assembly includes a gear having a base that extends about an axis between a first and second end. The first end defines a groove that extends to a floor and the groove surrounds the axis. Teeth extend from the base. A lip extends from the first end and also surrounds the axis. A cap has a flange that is inserted into the groove. The lip is deformed toward the groove such that material from the lip flows to trap the flange between the lip and the floor of the groove to retain the cap to the gear in the axial direction. Slots may be defined in the flange such that the material from the lip flows into the slots to provide a key-lock between the cap and the gear to prevent rotation of the cap relative to the gear about the axis.

An improved air foil bearing assembly is disclosed. The air foil bearing assembly includes a bearing housing having an axially extending bore therein and a shaft arranged within the bore for relative coaxial rotation with respect to the bearing housing. The shaft cooperates with the bearing housing to define an annular gap therebetween. A foil assembly is disposed in the annular gap, including at least one foil having at least one laterally extending tab. The tab is adapted to be received in and extend axially from the annular gap and is further adapted to be bent into frictional contact with an outer surface of the bearing housing to militate against axial movement of the foil.

A programmable vehicle accessory service allows a user to configure vehicle accessories. The user enters configuration data at an application. The application may be located at a personal computer, laptop, mobile telephone, or other device. The configuration data is transmitted to a remotely located server or controller. The controller processes the configuration data and generates vehicle accessory parameters according to the configuration data. The controller transmits the parameters to a module located in the vehicle. The module converts the parameters to a proper vehicle bus communication format and adjusts vehicle accessories according to the parameters. Additionally, the controller may transmit the parameters to a user device such as a laptop, mobile telephone, or personal data assistant. The user uploads the parameters from the user device to the module.

Methods and systems for using compressed gas in a vehicle. The methods include generating mechanical energy by expanding stored compressed gas through a turbine-compressor and distributing the mechanical energy to the engine, motor-generator, or a wheel. The compressed gas vehicle system includes a flask connected to a turbine-compressor, which may be interconnected to the engine and the motor-generator. The system may also include an electric wheel-motor connected electrically to the motor-generator.
