1. A brake device, to be installed on a driving axle comprising:
a first brake disc comprising:
a supporting disc assembled on the axle, configured to share rotation with said axle and to be moved in an axial direction with respect to the axle;
a first lining rigidly assembled on a first surface of the supporting disc; and
a second lining rigidly assembled on a second surface of the supporting disc;
a first container disc, configured to be moved only in the axial direction of said axle; and
a second container disc configured to be moved only in the axial direction of said axle or to remain stationary;
wherein the first brake disc is positioned between the first container disc and the second container disc;
wherein the first container disc is configured to be moved in the axial direction towards the first lining of the first brake disc;
wherein,
the first container disc is configured to exert a pushing pressure on the first lining in the axial direction, generating braking, and moving the first brake disc with respect to the axle towards the second container disc;
wherein each container disc comprises an inner circuit configured to accommodate the passage of a coolant configured to cool it;
wherein the supporting disc is formed by a cast iron part comprising:
a central disc through hole comprising the axial direction;
a plurality of fins arranged on the perimeter of the central disc through hole; and
at least one sliding joint accommodation, positioned on the perimeter of the central hole, comprising the axial direction; and
wherein the brake device comprises at least one guide disc comprising:
a central through guide hole comprising the axial direction;
at least one guide shaft positioned in a position eccentric to the central guide hole and comprising the axial direction;
wherein the guide disc is rigidly fastened to the axle and is assembled on a supporting disc in a joint sliding in the axial direction, the central guide hole being concentric to the central disc through hole; and
wherein the at least one guide shaft is configured to be accommodated in the at least one accommodation of the supporting disc.
