ABSTRACT:
A suction type road sweeping vehicle includes a fluid coupling in the drive train between the auxiliary engine and the vacuum generating fan. The fluid coupling is mounted integrally with the engine flywheel and drives a step up gearbox. The flywheel, coupling and gearbox are housed in a compact housing attached to the engine and routine in the coupling. The use of the fluid coupling alleviates vibrational problems associated with elastic properties in existing couplings and thereby enables a more robust fan having a greater moment of inertia to be used.
