A torque ripple compensating device for an internal combustion engine is provided. The torque ripple compensating device comprises a first member, a second member, and a third member. The first member is in driving engagement with an output of the internal combustion engine. The second member is in driving engagement with the first member. The third member is in driving engagement with the second member. An angular deviation between the first member and the third member causes a cyclical acceleration of the third member. The cyclical acceleration of the third member applies a torque to the output of the internal combustion engine through the first member. The torque ripple compensating device is able to be passively or dynamically adapted for both an amplitude and a phase of a torque ripple while minimizing an interference with an operation of the internal combustion engine.

Torque ripple compensating device

A variable transmission includes various powerpath layouts consisting in either; a single mode with approximately symmetrical reverse and forward speeds and includes an input shaft, one or two planetary gear sets, or a planetary gear set and a compound gear set when the RTS (ring-to-sun) ratio of the planetary gear set is not physically possible; or a dual mode with each mode being selected by closing a clutch/brake and releasing the other. A first up-speed planetary gear set on the input side of a variator, and a second planetary gear set on the output side of the variator, both configured to split the torque when drivingly engaged with a variator comprising, a first ring assembly, and a second ring assembly. Various up-speed ratio arrangements are shown that tend to increase the speeds and decrease the torque acting on the CVP, allowing a decrease in the variator size.

Infinite variable transmission with planetary gear set

A method of vehicle and operator guidance by pattern recognition begins with collecting data on vehicle and operator patterns through sensors. The collected data is combined and analyzed with a pattern recognition algorithm. The combined and analyzed data is compared with patterns in a pattern database. If data matches a pattern in the pattern database, the pattern can be selected. If the data does not match a pattern in the pattern database, a new pattern can be created and selected. Based on the selected pattern, a determination is made to passively assist the operator, selectively assist the operator or passively and actively assist the operator. The determined action is then implemented.

A variable transmission includes an input shaft, a planetary gear set drivingly engaged with a variator comprising, a variator carrier assembly, a first ring assembly, and a second ring assembly; and the output shaft, arranged to produce transmissions with continuously variable or infinitely variable output ratios.

Ball type continuously variable transmission

A turbocharger for use with an internal combustion engine is provided. The turbocharger comprises a differential device having a carrier portion, a compressor portion, and a turbine portion. The compressor portion is in driving engagement with a first portion of the differential device. The turbine portion is in driving engagement with a second portion of the differential device. The carrier portion of the differential device is in driving engagement with an infinitely variable transmission. The infinitely variable transmission is in driving engagement with the internal combustion engine. The turbocharger is simply controlled, reduces turbo lag, decreases a boost threshold of the turbocharger, and increases an efficiency of the internal combustion engine.

Variable transmissions and drivelines using such transmissions having a direct drive mode, a reverse mode, and a continuously variable mode of operation using a continuously variable variator in combination with a gearbox having a one or two speed forward gear, a reverse gear, and a direct drive clutch. The direct drive clutch transfers power from the input shaft directly to the gearbox by running the variator in a unitary (1) speed ratio configuration, or by bypassing the variator altogether by using a set of clutches that disconnect the variator from the input shaft. Additional gears may be provided in the gearbox.

Ball type CVT including a direct drive mode

A driveline for a vehicle is provided. The driveline includes a power source, a planetary gearset, a lockout clutch, a transmission, and a kinetic energy recovery system. The planetary gearset includes a sun gear, a carrier having a plurality of planet gears rotatably disposed thereon, and a ring gear. The power source is in driving engagement with a portion of the planetary gearset. The lockout clutch is capable of placing the planetary gearset in a locked out condition. The transmission is in driving engagement with another portion of the planetary gearset. The kinetic energy recovery system includes an accessory clutch and a flywheel. The accessory clutch facilitates driving engagement between the flywheel and another portion of the planetary gearset. The lockout clutch and the accessory clutch are selectively engaged to facilitate a transfer of energy to and from the transmission and the flywheel.

Hybrid drivetrain and method of operation thereof

A torque vectoring device includes a drive member engaged with a power source, a plurality of variator ball assemblies configured to be tiltable and rotatable with respect to the drive member, a first output frictionally engaged with the variator ball assemblies, and a second output frictionally engaged with the variator ball assemblies. A torque distribution between the first output and the second output may be adjusted by tilting the plurality of variator ball assemblies. The variator ball assemblies also facilitate a differential action between the first output and the second output.
