Abstract
A system and method for managing inertial torque reactions on stationary powertrain structure rotate at least one selected engine component and at least one selected drive train component in opposite directions so the rotational inertia of the selected drive train component acts in a direction opposite to that of the rotational inertia of the selected engine component to reduce or eliminate the inertial torque reactions on stationary powertrain structure caused by rotational acceleration and deceleration of powertrain components and improves performance with respect to noise, vibration, and harshness (NVH).
Claims26
A method for managing inertial torque reaction in a vehicle having an engine and a drive train, the method comprising:
- operating the drive train to rotate inertia in a direction opposite to rotating inertia created by operation of the engine.
A method for managing inertial torque reaction in a powertrain having a prime mover and a drive train, the method comprising coupling the prime mover to the drive train using a device that reverses direction of rotation of a drive train inertial component relative to direction of rotation of a prime mover output component.
A system for managing inertial torque reaction in a vehicle having a powertrain including a prime mover and a drive train, the system comprising a device for coupling the prime mover to the drive train such that the drive train generates a rotational inertia reaction torque in a direction opposite rotational inertia reaction torque generated by the prime mover.
A system for reducing vibration associated with operation of a vehicle, the system comprising:
- a prime mover having an output component that rotates during operation;
- a transmission having an input component;
- and
- a device for coupling the output component of the prime mover to the input component of the transmission so that the input component rotates in a direction opposite to the output component of the prime mover.
