"AXLE BRAKE FOR GEARBOX GEARBOX STAGE WHERE IN A FIRST BRAKE ELEMENT IS INTEGRATED WITH AND CONSTITUTES PART OF THE AXLE". The present invention relates to an axle brake (120, 220) for a motor vehicle having a stage gearbox (1). The axle brake (120, 220) comprises a first friction surface brake element (128), brake element (128) which is rotatably coupled to the axle (105), and a corresponding second friction element. (127, 227) which is rotatably coupled to a gearbox housing (15, 16) and where the friction surface of the second brake element (127, 227) is intended to interact with the brake surface. friction of the first brake element (128) by virtue of the fact that the first brake element (128) and the second brake element (127, 227) are of movement relative to each other in the axial direction, where the friction surfaces, under contact, brake the shaft (105). In accordance with the present invention, said axle brake is characterized in that the first brake element (128) is integrated with and constitutes part of the axle (105), and also that the cover (221) is integrated with the gearbox housing (15, 16) or the clutch housing (215), and furthermore a cup spring (230) for return of the piston (222) and friction surfaces is disposed between the piston (222) and a rotatably secured portion (133) disposed in the gearbox (1), and furthermore that the axle brake has an intermediate shaft (105) in the gearbox (1).
