Definitions

  • the invention relates to a vehicle brake system with a gas pressure accumulator has a housing whose interior by a metal bellows and one on the Metal bellows gas-tightly attached disc in a gas space filled with gas and a fluid space is divided, the fluid space through a supply line a fluid underneath Pressure can be supplied and removed, and between the fluid space and the supply line a valve arrangement is provided which closes when the pressure in the Supply line falls below a minimum value, and opens when the pressure reaches the minimum value exceeds, the metal bellows when supplying and discharging the fluid Performs lifting movement by means of which the valve arrangement is actuated. Furthermore concerns the invention such a gas pressure accumulator.
  • Vehicle brake systems exist with regard to functionality and safety of the aggregates particularly high requirements.
  • the object of the invention is therefore a safe and reliable vehicle brake system provide.
  • the object is according to the invention by a vehicle brake system at the beginning mentioned type solved with a gas pressure accumulator, which has the features of the claim 1 has. Furthermore, the object is achieved by such a gas pressure accumulator. Since the metal bellows performs a lifting movement when the fluid is fed in and out, by means of which the valve arrangement is actuated is the closing of the fluid space directly coupled with the movement of the metal bellows, creating an in itself closed security system is formed.
  • a coaxial mandrel is advantageously connected to the hollow cylinder, on which the Piston guided or which is guided in the piston. This is a guided movement of the piston relative to the sealing seats possible and at the same time a compact Design of the gas pressure accumulator achieved.
  • the metal bellows is essentially hollow cylindrical trained and the piston and the hollow cylinder are radially inside in the metal bellows arranged so that a particularly compact design is achieved.
  • An advantageous embodiment provides that the lifting movement of the metal bellows from two end stops is limited to defined end positions for the moving components pretend.
  • the valve arrangement is at the same time in the end positions closed.
  • a seal or a sealing seat is advantageous on at least one end stop educated.
  • a redundant seal is formed at the end stop, which enables a particularly good seal.
  • the redundant seal is arranged particularly advantageously on the end stop, which the basic position of the Piston limited.
  • the gas pressure accumulator is particularly well sealed, if the pressure in the supply line is less than the permissible minimum pressure.
  • the pressure in the supply line the so-called system pressure of the vehicle brake system especially with longer vehicle downtimes below this minimum pressure so-called gas pre-pressure decrease.
  • the gas pressure accumulator can also be provided with a valve arrangement which is provided at least one redundant seal on an end stop, but does not have the dual function described above.
  • a valve arrangement touches the piston first as a closing element during a closing movement a first sealing seat and seals it. Then the piston touches a second sealing seat which forms an end stop for the closing element, and seals this redundantly.
  • the first sealing seat can be one of those described above Correspond to sealing surfaces.
  • the piston is advantageously arranged at least one seal against at least one Can seal seat.
  • a gas pressure accumulator 10 shown in FIGS. 1 and 2 has a cup-shaped one Housing 12, which is closed with a cover 14.
  • the interior of the Housing 12 is of a metal bellows 16 adjoining the cover 14 and one disc 18 fastened thereon in a gas-tight manner into a gas space 20 and a fluid space 22 divided.
  • the gas space 20 is filled with a gas under pressure.
  • the lid 14 is penetrated by a feed line 24 through which a fluid flows into the fluid space 22 is supplied when the pressure in the supply line 24 increases.
  • the fluid is in the fluid space 22 stored and discharged from this when the pressure in the supply line 24 drops.
  • the housing 12 has a cylindrical outer wall 26 with a longitudinal axis 28.
  • a disc-shaped end wall 30 adjoins the outer wall 26, in the coaxial a threaded bore 32 is formed through which the gas enters the gas space 20 a so-called gas pre-pressure can be supplied.
  • the threaded bore 32 is closed with a screw plug 34 which rests on a sealing washer 36.
  • the lid 14 has a disc-shaped closure section 38 which by means of a circumferentially formed shoulder 40 in the outer wall 26 of the housing 12 centered and supported on this.
  • the disc-shaped closure section 38 is connected to the outer wall 26 in a gas-tight manner by a weld 42.
  • the interior of the Housing 12 facing side of the closure portion 38 coaxially a hollow cylinder 44 and a mandrel 46 formed in one piece.
  • a connection 48 is integrally formed, which by substantially axially directed bores 50, 52 and 54 with the interior of the Housing 12 is connected.
  • the metal bellows 16 is folded, essentially cylindrical and on both of them axial ends by welds 56 and 58 to the closure portion 38 and the disc 18 connected gastight.
  • the disc 18 is oriented axially and in one piece with a coaxial rod 60 connected, in which an axial bore 62 is formed, by means of which the rod 60 is guided on the mandrel 46.
  • a piston 64 connects in one piece to the rod 60, whose diameter is larger than that of the rod 60.
  • sealing surfaces 66 and 68 are formed, which are axially directed and each form a sealing seat. There is a recess axially between the sealing surfaces 66 and 68 70 formed on the inner circumference of the hollow cylinder 44, so that its Diameter in this area larger than the diameter of the sealing seats on the Sealing surfaces 66 and 68 is.
  • the piston 64 has a circumferential groove in which a seal 72 in the form of a Sealing ring is inserted or injected.
  • the seal 72 is designed so that it cooperates with the sealing surface 66 or 68 and thereby a valve arrangement 74 forms, which can seal twice liquid-tight.
  • Fig. 1 the metal bellows 16 is shown in a position in which almost no fluid is stored in the gas pressure accumulator 10, that is to say the pressure in the fluid space 22 Minimum value, the gas admission pressure has reached.
  • the piston 64 is there almost in a basic position, in which the seal 72 rests on the sealing surface 66 and seals it.
  • the valve arrangement is therefore between the supply line 24 and the fluid chamber 22 closed.
  • the piston 64 with the seal 72 can each slide along an axial stroke X 1 or X 2 .
  • the seal remains during these stroke paths X 1 and X 2 , while a slight pressure equalization between the fluid space 22 and the antechamber 76 is possible. In this way, elasticity and thermal expansion can be balanced as described above.
  • a chamfer 78 is located in the axially lower, inner end of the piston 64 in FIG. 1 formed and on the closure portion 38 a piston 64 opposite End stop 80, against which the piston 64 can rest in a defined manner.
  • An end stop 86 is formed on the inside of the end wall 30, against which the Disc 18 is in the upper end position of piston 64 in relation to FIG. 1.
  • Fig. 2 shows an embodiment of a gas pressure accumulator 10, which is similar to that 1 is constructed. However, in this gas pressure accumulator 10 Disc 18 is integrally connected to the rod 60 and a hollow cylinder 44 '.
  • the Rod 60 is guided axially displaceably in a bore 54 'of the mandrel 46 and by penetrates a bore 62 'which connects the bore 50 with the vestibule 76.
  • a piston 64' with the mandrel 46 ' integrally formed.
