Vehicle i.e. semi-hybrid vehicle, has variable transmission ratio driving unit modifying transmission ratio in operating modes when alterno-starter operates as alternator and operates as starter, respectively
Vehicle i.e. semi-hybrid vehicle, has variable transmission ratio driving unit modifying transmission ratio in operating modes when alterno-starter operates as alternator and operates as starter, respectively
The vehicle has a driving device (200) connecting a thermal engine (400) and an alterno-starter (300), where the device (200) has a variable transmission ratio driving unit (100). The unit (100) modifies a transmission ratio in an operating mode when the alterno-starter is driven by the engine and operates as an alternator. The unit (100) modifies the ratio in another operating mode when the alterno-starter is driven by the engine and operates as a starter. The device (200) has pulleys (201, 202) integrated to a crankshaft of the engine and a rotor of the alterno-starter, respectively.
