HYBRID POWERTRAIN |
摘要 |
<p>There is provided a hybrid powertrain (10) including (i) a combustion engine (20) operable to output rotational power thereat, (ii) an electric machine arrangement (60) being operable to output rotational power thereat, (iii) a gearbox arrangement (200) for receiving rotational power from at least one of the combustion engine (20) and the electric machine arrangement (60), and being operable to couple motive power to a load (230) coupled to the gearbox arrangement (200). The gearbox arrangement (200) is operable to provide a plurality of gearing ratios. The electric machine arrangement (60) is employable to extend a rotation rate range provided in a given gearing ratio: (a) at higher rotation rates prior to a gear change from said given gearing ratio to a gearing ratio subsequent thereto; or (b) at both lower rotation rates when accelerating from a standstill or from a preceding gear, and at higher rotation rates prior to a gear change from said given gearing ratio to a gearing ratio subsequent thereto.</p> |
