Embodiment Construction

[0026] figure 1 A hybrid powertrain 14 is shown containing a rotational energy source 10, which may be an internal combustion engine or any device capable of producing a rotational output. The rotating electrical machine 13 having the first rotatable member 15 and the second rotatable member 16 is electrically connected to an energy storage device 22, which may be any device capable of storing energy, such as a battery pack or a fuel cell. A rotating electric machine can be described in various ways as a dual-rotor electric machine or a rotating-stator electric machine.

[0027] exist figure 1 In the embodiment shown in , the output shaft 11 connects the engine to the gear set 12 . The gear set can be any device that provides a speed / torque ratio between the engine and the electric machine, and possible configurations include fixed ratio gear sets or multi-ratio gear sets, planetary sets with any number of components via the use of clutches or other The torque interrupt dev...

Abstract

A hybrid power train 14 including an electrical rotating machine 13 in the form of a rotatable stator electric machine having first 15 and second 16 rotatable members and an energy storage device 22 is described. First, second and third 17, 18, 19 mechanical coupling devices or clutches are capable of being selected to reversibly connect the first rotatable member 15 to the output of the engine, the second rotatable member 16 to the output of the engine and to connect one of the rotatable members to a ground point respectively. The hybrid power train operates in a mode according to which of the clutches are selected to connect. By changing between modes the efficiency of the source of rotational energy and the rotatable stator machine can be optimised based on the current required performance of the vehicle producing an overall efficiency gain across a wide range of driving conditions. Optionally, a planetary gear set is included.

Description

technical field [0001] Embodiments of the present invention relate to hybrid powertrains, and more particularly, to interconnecting the output of an engine to a drive, the hybrid powertrain including a rotating electric machine having two electrical rotating members and configurable as an electric motor or generator operation. The hybrid powertrain also includes three mechanical coupling devices that can be selected to reversibly couple the various components of the drive, allowing the hybrid powertrain to operate in different modes. The hybrid powertrain also includes an energy storage device for supplying electrical power to the rotating electrical machine when it operates as an electric motor, and for storing electrical power from the rotating electrical machine when the rotating electrical machine operates as a generator. Background technique [0002] Currently, most road vehicles use an internal combustion engine powered by gasoline, diesel, ethanol, liquefied gas, bio...
