摘要

The joint has a drive wheel (6) connected with a drive shaft (7), and a motor with a hollow shaft inserted between the drive shafts. A drive is deflected by a bevel gear (9), and a gear transmission ratio is freely selectable by the bevel gear. A carriage (10) is fastened at a cross head and freely supported by a receiver (11) so that the carriage is adjusted for uneven surfaces. A vertical roller is fastened between the idle rollers for centering the drive. The cross head is screwed together with cross bars. A base is formed by a carrier made of steel.
