RULES OF ADMINISTRATION FOR A NATIONAL USEFUL VEHICLE

摘要

A drive system for a utility vehicle has at least one rear axle, which can be permanently driven from a drive engine via a speed-change gearbox, and a front axle which is operatively connected to the rear axle by an axle engagement clutch that can generally be controlled manually for engagement and disengagement. In order to avoid the risk of the driver's failing to recognize the need for engagement of the axle engagement clutch in the case of difficult traction of the utility vehicle on an adherent roadway and of the rear axle being overloaded as a result, provision is made for the engagement of the axle engagement clutch to be initiated automatically as a function of the engine load.
