Drive unit comprising an internal combustion engine, a device driven by the latter and a universal joint connecting the two

摘要

In a drive unit comprising an internal combustion engine (5) which generates torsional vibrations about the axis of its output shaft (1) as a function of its load and speed and further comprising a device (gearbox 8) connected to its output and having an input shaft (2), the casings of the engine (5) and the device (8) connected to its output are connected via a swivel joint (17) and the input and output shafts (2, 1) are connected via a universal joint (3), forming an angle ( alpha ) between the shaft axes which can be varied by means of an adjustment device (18) for the purpose of minimising the excitation of vibrations (Figure 3). <IMAGE>
