BLOQUE DE MANDO DE FRENOS PARA VEHICULO Y SU APLICACION A UN SISTEMA DE FRENADO.

摘要

1. Vehicle brake control unit, comprising at least one axial brake actuating spring (26), such as a helical spring, maintained in brake release position against the spring reaction force by a screw-nut system (33, 34) able to be rotatively driven by an electric motor (42), of which the electrical supply current is able to control the braking force of the unit, constituted of the axial reaction force of the spring (26) reduced by the substrating force provoked by the screw-nut system (33, 34) rotatively driven by the electric motor (42), characterized in that the spring (26) is connected to the brakes by means of at least one hydraulic master cylinder (12) of which the piston (13) is axially actuated by an abutment ring (25) of the spring (26), this ring being mechanically connected to the rotor (42b) of the electric motor (42) via the screw-nut system (33, 34) and in that at least one hydraulic fluid hose (22, 23) of the master cylinder (12) is connected in a manner known per se to at least one receiver cylinder (19, 20) of which the piston (4, 5) is able to apply at least one friction brake lining (6, 9) on a braking track (10, 11) of the vehicle.
