Open the CIPO recordAbstract From the Canadian patent
A differential is disclosed for driving the steering wheels of a multi-wheel-drive vehicle including holdout rings for maintaining in a disengaged condition an output shaft that overruns an associated output shaft by a given amount. In order to decrease the turning radius of the vehicle the lug portions on one holdout ring are angularly displaced relative to the lug portions on the other holdout ring, whereby the overrunning output shaft is maintained in a disengaged condition during a sharp turn that produces overrunning of the output shaft above a given value.
