Abstract: A simulation device for an electrically controlled braking apparatus of a vehicle with an electric motor having a motorized axis slant in relation to the translation axis of the strut of the pedal group, a contrast body connected to the strut, a main abutment wall and an elastic contrast element, disposed between the main abutment wall and the contrast body. The method of applying the contrast action to the pedal provides for activating, when the flattening action of the pedal by the user is terminated, the motor to achieve an inactive configuration in which the useful distance of maximum compression of the elastic contrast element is minimal.

Abstract: A wheel assembly for a vehicle includes a wheel rim suitable to rotate around an axis of rotation (a-a), defining an axial direction (A-A) parallel or coincident with the axis of rotation (a-a), an orthogonal radial direction (R-R), and a circumferential direction locally coincident with a tangential direction (T-T) orthogonal to the axial direction (A-A) and the radial direction (R-R), the wheel rim having a radially outer side, opposite the axis of rotation (a-a), and a radially inner side facing the axis of rotation (a-a), the rim being suitable to receive externally a tire, and wherein the wheel rim forms internally a cylindrical chamber of the rim delimited radially from the inner side; a motor comprising a rotor and a stator; the rotor being supported, free to rotate, on the stator; said stator being fixed to a stator support; the motor being housed in the cylindrical wheel rim chamber of the wheel rim; the rotor is selectively, removably and rigidly connected to the inner side of the wheel rim, avoidin

Abstract: The present invention relates to a brake piston with reduced transmission of heat from the disk to the brake fluid. In particular, the present invention relates to a disk-brake piston (7) characterized in that it comprises a cup (12) having a skirt (14) and a head portion (15), and a tubular insert (13) housed in the cup, a space for cooling air being defined between the outer surface of the tubular insert (13) and the inner surface of the skirt (14) of the cup (12).

Abstract: A master cylinder suitable for a vehicle braking system has an unusual capability to supply quantities of fluid and fluid pressures at its output in differentiated manner in dependence on the braking stage, preventing long transitory stages between an approach stage and an actual braking stage. The cylinder comprises a cylinder body having a first chamber and a second chamber provided inside. The first chamber is in operative communication with at least one braking member and houses a first piston. The second chamber, which has larger transverse dimensions than the first chamber, is in operative communication with the first chamber and houses a second piston. Ducts are provided and put the first chamber and the second chamber into communication during the approach stage. The ducts house a low-pressure valve which is open during the approach stage and closed during the actual braking stage.
