Abstract
The present invention teaches an activation apparatus for a differential pawl. Such activation apparatus is designed to prevent damage to components of the differential pawl and/or of the drive train resulting from operator error. According to the invention, when a drive wheel slips, a first apparatus acquires a slip signal; and when a slip signal is present, a second apparatus prevents the pressurization of a pressure-medium-operated actuator apparatus of the activation apparatus.
