Abstract
An assisted steering system is provided. In preferred embodiments, the system has driver and assist pinions that are out of phase with each other. As a tooth of the driver pinion is fully engaged with a rack tooth, a tooth of the assist pinion is only partially engaged with a tooth of the rack. Preferably, the driver and assist pinions have differing rack speeds and numbers of teeth.
