OPERATION OF A DIFFERENTIAL LOCK

摘要

The operation of a differential lock consists essentially of a lock differential (10) and the clutch (11) linked therewith, which by means of an electromagnetic positioning element (12) connects the engagement shaft (13) with the part of the locking differential driven via the universal joint shaft for such a time as a presettable deflection angle stop value is reached or exceeded. The sole signal switch (7) used for this can, as desired, be designed as a contact directly incorporated in the circuit of the electromagnetic setting element (12), or an induction switch, or as a potentiometer in the region of the angle-dependent moving deflection elements and can be maintained, protected from damage, in the axle housing (2). The switch (7) can be combined via further switches (17) and (30) either by the driver manually or with the insertion lever for the additional drive on the steering axle (1), so that the locking differential (10) can only be switched in automatically in certain driving conditions. The frequency of switching of the locking differential (10) is thus restricted to important cases of necessity and an easier and more sturdy switching technique is achieved.
