Definitions
- the invention relates to a brake device for a hydraulic brake system of a vehicle with a liquid container.
- Fluid reservoirs are used to supply pressure medium to hydraulic units in vehicles, such as brake devices for hydraulic motor vehicle brake systems.
- Such liquid containers are usually connected to the housing of the unit by means of one or more connecting pieces, which are clamped in corresponding receiving seats by means of elastic sealing elements.
- Such a non-positive clamping connection cannot absorb the forces arising during operation and in particular during the initial pressure filling with sufficient certainty. It is therefore known and common practice to connect the liquid container to the housing of the unit in a non-positive manner at a separate attachment point.
- DE 102017215833 A1 discloses such a fastening device for fastening a liquid container to an auxiliary brake cylinder.
- a locking pin is inserted and fixed through a through-opening formed directly in the housing of the main cylinder and through two fastening lugs of the liquid container flanking this through-opening.
- the through opening is usually positioned in the longitudinal direction between two receiving seats.
- housings of such braking devices are designed as a flydraulic block, the interior of which is densely occupied by a large number of flydraulic channels, connections, valves and sensors and connections. With such a hydraulic block, it is often very difficult if not impossible to integrate a favorable position for a form-fit fastening point of the liquid container.
- the invention provides that a mating interface of the fastening point is arranged on a separate assembly component which is connected to the housing.
- the position for the fastening point can be selected in a force-optimized and stress-reduced manner, independently of the internal structure of the housing.
- the mounting component can be provided for mounting the braking device on the vehicle.
- the filler neck and the container interface can be arranged essentially at opposite ends of the liquid container along a longitudinal axis oriented transversely to the direction of insertion of the connecting piece, which reduces the load on the fastening point through an optimal leverage ratio.
- the fastening point can preferably be secured by means of a safety element that can be inserted in the transverse direction through the mating interface, which is locked in a locked position in a locking seat formed on the container interface, the locking in the locking seat preferably being set up to be reversibly detachable.
- the snap-in seat can be set up to accommodate a snap-in section of the securing element spatially aligned along the transverse axis in the locked position, wherein the snap-in seat can be configured particularly preferably flush with the mating interface for simple straight-line plug-in assembly.
- the snap-in seat can also be set up to accommodate a snap-in section of the securing element spatially aligned along the longitudinal axis in the locked position, which is particularly advantageous when there is little installation space at the side of the fastening point.
- the attachment point can also be secured by means of a securing element designed as a screw, which interacts with a thread arranged in the mating interface.
- the assembly component is designed as a flange element which is mechanically connected to the housing and includes at least one assembly interface for a screw connection for attachment to the vehicle.
- FIG. 1 shows a highly simplified representation of the structure of the braking device and its arrangement in the vehicle, which is not to scale.
- FIG 2 shows a first exemplary embodiment of the fastening device with a transverse pin, two spatial views (a, b).
- FIG. 3 shows a simplified cross-sectional representation of the fastening device according to FIG. 1.
- Fastening device with an angle pin in a pre-assembly position (a) and a locked final position (b).
- Fastening device with a U-pin in a pre-assembly position (a) and a locked final position (b).
- Fastening device with a screw connection with differently aligned screws (a, b, c).
- FIG. 1 shows, in a highly simplified manner and not true to scale, a basic representation of a brake device 100 according to the invention for a hydraulic motor vehicle brake system mounted in the vehicle.
- the braking device 100 shown is actuated directly by a driver via a mechanical actuator 11 . However, this limits options for positioning the braking device 100 in the engine compartment to a predetermined location in a dash panel 17 .
- the brake device 100 shown has a cuboid housing 2 designed as a valve block. Seen along a flat axis H, a liquid container 1 is positioned on the housing 2, which is used to supply the brake device 100 with a hydraulic pressure medium. For this are at the Liquid container 1 has two connecting pieces 14,14' formed on. The connecting pieces 14,14' are inserted into corresponding receiving seats 15,15' in the housing 2 along a vertical axis H and are sealed and clamped therein by means of elastic sealing elements 12,12'.
- a filler neck 5 provided for filling the liquid container 1 must therefore be offset comparatively far in the longitudinal direction L.
- the first filling of the brake system in the vehicle factory is usually carried out using a special filling system as a so-called pressure filling.
- a special coupling (not shown here) is attached to the filler neck in a sealing manner, whereupon a vacuum is generated in the brake system and the hydraulic pressure medium or brake fluid is sucked in abruptly via the filler neck 5 .
- Fb comparatively high force
- Fb which is directed counter to the vertical axis H
- a fastening point 3 that acts in a form-fitting manner is provided on the braking device 100 .
- this is arranged at an opposite end of the liquid container 1 in relation to the filling nozzle 5 in the longitudinal direction L, because the resultant force Fr acting in the direction of the vertical axis H is lowest there due to the favorable leverage ratio.
- the fastening point 3 comprises a container interface 6 which is formed on the liquid container 1 and which is assigned to a corresponding mating interface 7 outside of the liquid container 1 .
- the two interfaces 6.7 are secured via a separate pin-shaped securing element 9 connected, whereby a secure form fit is created and the levering out of connecting pieces 14,14' is prevented.
- the flange for mounting the braking device 100 on the bulkhead 17 is designed as a separate mounting component 4 .
- the assembly component 4 has corresponding assembly interfaces 13, 13' for assembly of the braking device 100 on the bulkhead 17 and is at the same time mechanically connected to the housing 2 by means of connecting elements 19, 19'.
- the assembly interfaces 13, 13' are provided as standard screw bolts, for example, which are inserted into the assembly component 4 and secured against torsion.
- the mating interface 7 of the attachment point 3 is formed on the assembly component 4 so that the liquid container 1 is attached to the housing 2 and to the assembly component 4 at the same time.
- the braking device 100 has an additional, second fastening point 18. This is positioned as a simple screw connection on the filler neck end of the housing 2 and is essentially intended to absorb vibrations and forces acting upwards on the liquid container 1. Such forces can arise, for example, in ferry operations on uneven roads.
- a bulkhead 17 in a motor vehicle is often oriented at a slight incline to the floor axis H of the vehicle, as a result of which the longitudinal axis L, the vertical axis H and the transverse axis Q of the liquid container 1 may in practice not be exactly, but at least approximately the Longitudinal vertical and transverse axis of the vehicle correspond.
- FIG. 2 shows a first embodiment with a preferred embodiment of the fastening device 3 in two spatial views.
- the container interfaces 6,6' are arranged on the fastening tab 20,20' on the liquid container 1, whereas the counter-interfaces 7,7' on rib-shaped projections 21,21' of the mounting component 4 are positioned.
- a pin-shaped securing element 9 is inserted in the transverse direction through corresponding through-openings of container interfaces 6,6' and counter-interfaces 7,7' and secured against falling out.
- Fig. 3 shows in cross section the attachment point 3 according to the embodiment of Fig.2.
- a snap-in seat 8,8' is arranged at the container interfaces 6,6' in alignment with the mating interfaces 7,7'.
- the pin-shaped securing element 9 has a latching section 10 at one end, which is set up for latching in the latching seat 8 or 8'.
- the latching section 10 is designed as a hemispherical thickening of the securing element 9, which is encompassed by a plurality of elastic spring tabs of the latching seat 8. The securing element 9 is thus securely held in the locked position shown here, but can be pulled out without damage and thus fully reversible by applying a corresponding amount of force.
- the securing element 9 can be plugged in from both sides because of the symmetrical structure of the preferred embodiment shown, whereby the same components can be used for right-hand drive and left-hand drive vehicles, for example.
- the counter-interface 7 is designed as a through-opening, aligned parallel to the transverse axis Q, in a projection 21 on the assembly component 4.
- FIG. The fuse element 9 is L-shaped. To fix the liquid container 1 in place, the securing element 9 is inserted into the counter-interface 7 along the transverse axis Q and rotated about the transverse axis Q in the direction of the liquid container 1 .
- the latching section 10 is in one elongated, trough-shaped, aligned along the longitudinal axis L snap-in seat 8 of the container interface 6 clipped or doctored des.
- the securing element 9 is designed in a U-shape here.
- the snap-in seat 8 on the container interface 6 has an elongated, trough-shaped design comparable to the embodiment according to FIG.
- the securing element is inserted in the transverse direction into the mating interface 7, rotated in the direction of the liquid container 1 and latched with the latching section 10 in the latching seat 8.
- a stop surface 16 is formed on the container interface 6, which prevents the safety element 9 from slipping out further against its plug-in direction in the locked position.
- the securing element 9 is provided as a screw which is screwed into a threaded hole formed in the mating interface 7 and not explicitly shown here.
- the securing element 9 can be aligned along all spatial axes within the invention.
