Drive system for portable machine using rotation of vehicle wheel e.g. for portable electrical generator, pump, conveying screw or winch

摘要

The drive system has a vehicle wheel (2) used as the drive for rotation of 2 driven rollers (3) via a friction coupling, with a belt drive (4) between the driven rollers and the shaft (8.2) of the portable machine (1), which is provided with an electronic regulation device. The driven rollers and the belt drive are mounted on a hydraulic lifting jack (6), the axes of the rollers extending parallel to the shaft of the machine, with axial adjustment of the rollers for matching the width of the vehicle wheel.
