Vehicle Differential Lock Disengagement Bypass

摘要

A method and system for bypassing a control valve that would otherwise disengage differential and/or inter-axle locking means. The bypass is achieved by a valve that can be actuated by a vehicle condition change.

1. A method for selectively bypassing a disengagement system for differential locking means in a vehicle having a selectively lockable differential, the differential locking means disengageable by means of a control valve in communication with the differential locking means, the method comprising the steps of:
a. providing a bypass valve moveable between first and second positions; b. positioning the bypass valve between the control valve and the differential locking means; c. setting the bypass valve in the first position, thereby allowing unimpeded communication between the control valve and the differential locking means; and d. selectively actuating the bypass valve to move the bypass valve to the second position, thereby blocking communication between the control valve and the differential locking means and preventing disengagement of the differential locking means.
