Patent ID: 7302871

Claim:
An oscillation generating device for use in a soil compacter, comprising a first unbalance shaft pair and a tipping moment compensation device wherein a second unbalance shaft pair is arranged adjacent to the first unbalance shaft pair as the tipping moment compensation device wherein the unbalance shaft pairs rotate in opposite directions, and diagonally opposite unbalance shafts rotate in the same direction, wherein the unbalance shafts of the first unbalance shaft pair are offset in crossed symmetry, and in an axially parallel manner, relative to the unbalance shafts of the second unbalance shaft pair and wherein the spacings of the diagonally opposite unbalance shafts are different, wherein the diagonal unbalance shafts are coupled so that they rotate in unison and wherein the coupling rotating in unison includes a transmission with two crown gears, and spur gears on the unbalance shafts and meshing with them.
