ELECTRONIC CONTROL DEVICE FOR MANAGEMENT OF THE STEERING IN EARTH-MOVING MACHINES

摘要

The present invention relates to an electronic control device for management of the steering in earth-moving machines, essentially comprising a programmable logic electronic control unit (1) which is arranged as an interface between a pushbutton console (2) for setting a steering mode and an input diagnostics system (3) associated with the functions of the gearcase and the engine and with positioning of the wheels of the machine. The setting of a steering mode on the pushbutton console (2) is made possible by means of simultaneous selection of at least two switches (50). The input diagnostics system (3) of the electronic control unit (1) comprises a front wheel alignment sensor (28) and a rear wheel alignment sensor (29) which are respectively positioned in the region of the front and rear axles of the earth-moving machine and are designed to detect respectively the alignment position of the front and rear wheels with respect to the longitudinal axis of the machine itself.
