Abstract

A braking system for vehicles comprising —a manual actuator device, operable by means of a lever and/or pedal, operatively connected to at least a first braking device acting on a brake disc or drum, so as to exercise a braking action, —an automatic actuator device, operatively connected to said manual actuator device and/or to said first braking device, —at least one command panel which supervises the functioning of the braking system, said command panel being operatively connected to the automatic actuator device and being programmed so that when the manual actuator device is operated, the panel commands the operation of the automatic actuator device so as to be able to: —increase the overall braking action of the braking system, further operating the first braking device or further braking devices provided in said system and acting on further brake discs or drums, —control the braking action of the braking system so as not to further operate the first braking device or further braking devices of the system, —reduce the overall braking action imposed by means of the manual actuator device, directly countering the thrust action exercised on the lever and/or on the pedal.

22 . A braking system for vehicles comprising
a manual actuator device, operable by means of a lever and/or pedal, operatively connected to at least a first braking device acting on a brake disc or drum, so as to exercise a braking action, an automatic actuator device, operatively connected to said manual actuator device and/or to said first braking device, at least one command panel which supervises the functioning of the braking system, said command panel being operatively connected to the automatic actuator device and being programmed so that when the manual actuator device is operated, the panel commands the operation of the automatic actuator device so as to be able to: generate a braking action or increase the overall braking action of the braking system, operating and/or increasing the operation of the first braking device or further braking devices provided in said system and acting on further brake discs or drums, controlling the braking action of the braking system so as not to further operate the first braking device or further braking devices of the system, reducing the overall braking action imposed by means of the manual actuator device, directly countering the thrust action exercised on the lever and/or pedal.

23 . The braking system for vehicles according to claim 22 , wherein the command panel is programmed to command the automatic actuator device so as to operate the first braking device simultaneously with the manual operation imposed by the manual actuator device or by further braking devices provided in said system, when, following the manual operation of the manual actuator device, no blocking phenomena of the brake disc or drum occur.

24 . The braking system for vehicles according to claim 22 , wherein the command panel is programmed to command the automatic actuator device so as not to operate the first braking device or further braking devices provided in said system, when, following the manual operation of the manual actuator device, blocking phenomena of the brake disc or drum occur.

25 . The braking system for vehicles according to claim 22 , wherein the command panel is programmed to command the automatic actuator device so as to directly contrast the action of the manual actuator device, opposing the thrust action of the lever or pedal, when, following the operation of the manual actuator device, blocking phenomena of the brake disc or drum occur.

26 . The braking system for vehicles according to claim 22 , wherein the command panel is programmed to command the automatic actuator device so as to generate a braking action by operating the first braking device or further braking devices of the system, so as to stabilise the dynamics of the associable vehicle, and excluding the manual operation of the braking devices by the user.

27 . The braking system for vehicles according to claim 22 , wherein the manual actuator device is operatively connected to at least a first pusher of the first braking device and the automatic actuator device is operatively connected to at least a second pusher of the first braking device, said first and second pusher operating on the same brake disc or drum.

28 . The braking system for vehicles according to claim 22 , wherein the manual actuator device is operatively connected to at least one first pusher of the first braking device and the automatic actuator device is operatively connected to at least a second pusher of a second braking device, said first and second pushers operating on different brake discs or drums mechanically connected in rotation to each other.

29 . The braking system for vehicles according to claim 22 , wherein the manual actuator device is operatively connected to at least one first pusher of the first braking device and the automatic actuator device is operatively connected to at least a second pusher of a second braking device, said first and second pusher acting on different brake discs or drums mechanically separate from each other and connected so as to rotate to different wheels of an associable vehicle.

30 . The braking system for vehicles according to claim 29 , wherein the command panel is programmed to command the automatic actuator device so as to operate the second braking device so as to stabilise the vehicle, following the manual operation of the manual actuator device acting on the first braking device.

31 . The braking system for vehicles according to claim 22 , wherein the automatic actuator device comprises contrast means acting in opposition to the thrust of the lever or pedal.

32 . The braking system for vehicles according to claim 31 , wherein said contrast means act on the lever or pedal so as to oppose the increase in the operating stroke of the lever or pedal or to reduce said operating stroke.

33 . The braking system for vehicles according to claim 31 , wherein the lever or pedal pushes a piston fluidically connected to a hydraulic operating circuit of at least a first pusher of the first braking device, and wherein the contrast means, when operated, interrupt the fluidic connection between the piston and the at least one first pusher.

34 . The braking system for vehicles according to claim 31 , wherein the lever or pedal pushes a piston fluidically connected to a hydraulic operating circuit of at least a first pusher of the first braking device, and wherein the contrast means, when operated, exercise a thrust on the piston in opposition to the operating stroke and direction.

35 . The braking system for vehicles according to claim 31 , wherein said contrast means comprise a hydraulic device which generates pressure acting on the piston in opposition to the operating stroke due to the movement of the lever or pedal wherein the automatic actuator device comprises contrast means acting in opposition to the thrust of the lever or pedal.

36 . The braking system for vehicles according to claim 31 , wherein said contrast means comprise mechanical devices connected to the lever or pedal or to kinematisms connected to the lever or pedal so as to exercise a counter action such as to prevent the increase of the operating stroke or to reduce said stroke.

37 .
