Abstract (en)
[origin: EP2256248A1] The paver (F) has a primary driving aggregate (P) with a combustion engine (M) i.e. diesel engine, and functional units with hydraulic pumps, which are driven from a crankshaft of the engine. The functional units include a travel pump aggregate supplying a travel drive (16). A generator (G) supplies electric power to electric heating devices (H) and/or a paving screed (B) of the paver. A permanent drive train is provided between the crankshaft and the generator so that the pump is disconnected by a shiftable clutch from the crankshaft. Independent claims are also included for the following: (1) a method for heating-up heating devices (2) a method for driving a self-propelled paver (3) a method for starting and optionally warming-up a combustion engine of a primary driving aggregate of a paver.
