System for a power take off mechanism for a powertrain system
A system for a power take-off mechanism for a powertrain system is provided. The system includes an electrically powered torque generating device including a torque generating device output shaft and a transmission output shaft receiving mechanical power from the torque generating device output shaft. The system further includes a clutch selectively disengaging the transmission output shaft from the torque generating device output shaft and a power take-off module receiving mechanical power from the torque generating device.
Controls for vehicle systems including SCR exhaust aftertreatment and neutral at stop capability
A vehicle system includes an engine, a transmission including a torque converter, a clutch configured to selectably couple and decouple the torque converter, and a gearset, a selective catalytic reduction (SCR) exhaust aftertreatment system. An electronic control system may be operatively coupled with the engine, the electronically controllable clutch, and the SCR exhaust aftertreatment system. The electronic control system is configured to evaluate whether an SCR catalyst temperature satisfies at least one minimum temperature criterion, in response to the SCR catalyst temperature satisfying the minimum temperature criterion, permit a neutral at stop operation wherein the electronically controllable clutch is controlled to selectably decouple the torque converter and the one or more gears at least in part in response to the vehicle system being in a stopped state, and in response to the SCR catalyst temperature not satisfying the minimum temperature criterion, prevent the neutral at stop operation.
TORQUE CONVERTER AND DRIVE UNIT
A torque converter disposed between a prime mover and an output shaft is disclosed. The torque converter includes a cover, an impeller, a turbine, and a first clutch. The impeller is unitarily rotated with the cover. The turbine is disposed opposite to the impeller. The first clutch is configured to allow and block transmitting power outputted from the prime mover to the cover.
Systems and methods for improved catalytic converter performance during cold starts
An engine consumes fuel and air to generate an exhaust gas stream. An exhaust system channels the exhaust gas stream from the engine to a tailpipe. An aftertreatment system is included in the exhaust system and includes a catalyst. A transmission system is coupled with the engine. The transmission system includes a transmission and a torque converter coupled with the transmission through a shaft. A lock is included in the transmission system to selectively prevent rotation of the shaft to increase a load on the engine by the torque converter.
CONTROL OF A CONTINUOUSLY VARIABLE TRANSMISSION IN A MIXER
A transmission system for a feed mixer including a continuously variable transmission (CVT) is provided. The CVT includes a mechanical loop and a hydrostatic loop. The CVT is operated so that the mechanical portion of the CVT is prevented from overtaking the hydrostatic portion of the CVT at start up of the CVT.
Torque converter
A torque converter for a vehicle includes an impeller, a turbine, a stator positioned between the impeller and the turbine, a one-way clutch coupled to the stator and configured to couple to a fixed member, and a controllable clutch assembly. The controllable clutch assembly is configured to selectively engage the stator and the turbine such that the stator is able to rotate with the turbine to facilitate preventing the stator from reacting against the one-way clutch and applying a load to the fixed member and thereby facilitating reducing an output of the torque converter and reducing engine vibration during idle, and disengage the stator from the turbine to enable relative rotation between the stator and turbine.
Torque converter system for a vehicle
A torque converter system of a vehicle for delivering an input torque to a transmission may include a front cover of a torque converter receiving the input torque through a torque receiving shaft, an impeller of the torque converter receiving the input torque through the front cover, a turbine of the torque converter disposed opposed to and coaxially with the impeller and rotated by an operation fluid supplied from the impeller thereby driving a transmission input shaft, a reactor of the torque converter disposed between the impeller and the turbine and redirecting the operation fluid from the turbine toward the impeller, and a lock-up clutch disposed inside a transmission to selectively connecting the front cover and the turbine.
