Arrangement for allowing operation of power take-off unit mounted directly on thermal engine of road marking lorry to drive marking equipment assembly, has direct unit actuating pump to make equipment to function with parking or motion mode

摘要

The arrangement has a hydrostatic transmission and a mechanical drive that are joined together in a power divider (5). A direct power take-off unit (11) is mounted on a thermal engine (1) of a lorry to actuate a variable cubic capacity hydraulic pump (12) intended for a marking equipment (21) so as to make the equipment to function with various modes of the engine in parking or motion. The power take-off unit receives a clutch (20) mechanically to neutralize the hydraulic pump, and the pump delivers flow necessary to all functions of the equipment as for an idle mode of the engine.
