Abstract
A gearwheel for a gear system for a planetary gear system of a chassis assistance system. The gearwheel is divided into at least a first spur gear and a second spur gear which are spaced apart from one another along a common rotational axis. The gearwheel has, in addition, an open spring ring with a first end, which is supported in a circumferential direction against the first spur gear, and a second end, which is supported in the direction opposite to the circumferential direction against the second spur gear in such manner that by rotating the spur gears, relative to one another about the common rotational axis, the spring ring can be stressed in order to exert a restoring torque on the spur gears. A recess is formed on at least one of the spur gears for holding part of the spring ring.
