FLEXIBLE HYDRAULIC DEVICE FOR THE DRIVING OF VEHICLES PARTICULARLY UTILITIES AT A RELATIVELY HIGH SPEED OF THE MARKET

摘要

The invention relates to a flexible drive device comprising an integrated hydraulic transmission, and which makes it possible to provide the vehicles with either a conventional drive or a hydraulic drive with a relatively high speed, while giving the operator heat engine, which drives only the hydraulic pump, the possibility of rotating at a constant speed, and secondly a normal engine boost in the low and medium revolutions. / P P The device (first variant ) comprises two input shafts 8, 9, two output shafts 11, 12, two intermediate shafts 13, 14, a secondary output shaft 10 a hydraulic pump 5, a secondary drive shaft 15, a secondary clutch 6, an engine 7, and an accessory supercharger (not shown). When the driver establishes the hydraulic connection at the device, the hydraulic motor 7 drives the gearbox. s 4 via the clutch 6 and a mechanical transmission connecting the shafts 12 and 15. / P P The device is intended for driving private and commercial vehicles. / P
