Definitions

  • the present invention relates to a braking installation for a motor vehicle, this installation comprising a master cylinder controlled by a brake pedal and connected to a brake fluid reservoir and to wheel brake supply circuits.
  • the braking is essentially controlled by the driver of the vehicle, by means of the brake pedal which is connected to the piston of the master cylinder by a pneumatic servomotor, and the action of the driver on the pedal of brake determines the braking of the vehicle.
  • the document FRA1 -2654 816 mentions a braking system comprising a master cylinder provided at the outlet of the pressure of solenoid valves.
  • the present invention is intended to avoid these disadvantages of the prior art.
  • the master cylinder has a simpler structure than in the prior art and comprises fewer components and in which the dead races are removed or at least reduced.
  • a braking installation for a motor vehicle comprising a master cylinder controlled by a brake pedal and connected to a brake fluid reservoir and to wheel brake supply circuits, this installation being characterized in that that the brake fluid reservoir is connected to the master cylinder by means of a solenoid valve controlled connection means.
  • the master cylinder is a tandem master cylinder and comprises two working chambers which are each connected to the tank by a solenoid valve, each solenoid valve being open when the brake pedal or a driven element by this pedal is in the position of rest or non-braking, and being closed when the brake pedal or this element leaves the position of rest or non-braking.
  • Each aforementioned solenoid valve is closed in rest condition and is controlled by the computer to open from the output signal of a position or displacement sensor associated with the brake pedal or another element displaced by this pedal.
  • FIG. a master cylinder of a braking installation according to the invention.
  • the master cylinder of a braking system comprises a cylindrical body 10 in which two primary working chambers 12 and secondary 14 are delimited by primary pistons 16 and secondary 18, the primary piston 16 being associated by a push rod 20 to a pneumatic assist servomotor, not shown, itself controlled by a pedal of P.
  • the return springs 22 and 24 are arranged between the primary and secondary pistons 16 and between the secondary piston 18 and the front end of the body 10 of the master cylinder, in a conventional manner, and each working chamber 12, 14 is connected by a conduit 26, 28 respectively to F brake supply means mounted on the front wheels and on the rear wheels of the vehicle.
  • a reservoir 30 of brake fluid is mounted on the body 10 of the master cylinder and communicates with the chambers 12, 14 thereof by two passages 32, 34 respectively, each equipped with a solenoid valve 36, 38 respectively.
  • Each solenoid valve 36, 38 is controlled by a computer C and is closed in rest condition.
  • a position or displacement sensor 40 is associated with the push rod 20 or with another element whose displacement is controlled by action of the driver on the brake pedal, and provides an output signal 42 corresponding to the displacements of the rod. thrust 20 and applied to the computer C.
  • the solenoid valves 36, 38 are controlled by the computer when the primary and secondary pistons 16 and 18 of the master cylinder are in the rest or non-braking position shown in the drawing, that is to say when the driver Do not act on the vehicle's brake pedal.
  • any displacement of the push rod 20 resulting from an action of the driver on the brake pedal is detected by the displacement sensor 40 and transmitted to the computer which controls the solenoid valves 36 and 38 in closing. In this way, any action of the driver on the brake pedal immediately results in an increase in the pressure of the liquid brake present in the conduits 26 and 28 for supplying the wheel brakes, the dead races of displacement of the pistons of the master cylinder being suppressed.
  • the master cylinder has a simpler structure than in the prior art and comprises fewer components. Its assembly is simpler and its cost price is reduced.
  • the solenoid valves 36 and 38 are controlled by the computer in opening to allow the return of brake fluid to the reservoir 30, whenever necessary.
  • the senor 40 may be a position or displacement sensor which is conventionally associated with the brake pedal P to control the ignition of the lamps 44 brake signaling circuits ("stop lamps” ) when the driver of the vehicle presses on the brake pedal.
