Claim:
1. A transmission system for an adjusting device of a waste gate of an exhaust gas turbocharger, comprising: a three-part linkage mechanism, which has a driver arm that is operatively connected to a drive via a transmission, an output arm and a coupler, which operatively connects the driver arm and the output arm; wherein the transmission has a driving gear, assigned to the drive, and a driven gear, which is assigned to the driver arm and interacts with the driving gear; wherein the driving gear has a rolling curve radius, which changes over the circumference, and the driven gear has a rolling curve radius that runs complementary to the former; wherein the rolling curve radii are selected in an angle of rotation range about the extended position of the three-part linkage mechanism to form at least in a first region a first transmission ratio and outside the angle of rotation range to form at least in a second region a second transmission ratio that is larger than the first transmission ratio; and wherein the driver arm is connected in a rotationally rigid manner to the driven gear and is mounted with the driven gear in a common bearing, wherein a third transmission ratio is provided outside the angle of rotation range in a third region such that the second region is situated between the first region and the third region, the third transmission ratio being smaller than the second transmission ratio.
