Definitions

  • the invention is concerned with a threshold arrangement.
  • an effective obstacle threshold can only be passed at a very slow pace, the driver must brake in front of the obstacle in order to accelerate again, whereby many drivers also feel provoked and accelerate very quickly to excessive speed between two obstacle thresholds. This leads to increased noise and environmental pollution, which limits the benefits of such obstacle thresholds for residents. In addition, the flow of traffic is so disturbed that there are congestion in front of the obstacle thresholds in more frequented access roads from residential areas, which also leads to an increase in noise levels and environmental pollution.
  • the object of the invention is to provide a threshold arrangement of the type mentioned, in which the problems mentioned above do not appear.
  • the street threshold arrangement has a trigger threshold, an obstacle threshold arranged at a certain distance from it and an actuating device connecting the two thresholds lying transversely to the direction of travel, the obstacle threshold, which normally rests on the roadway level, being exceeded when the trigger threshold is exceeded Speed can be raised or lowered for a certain period of time by means of the actuating device in a position deviating from the roadway level.
  • obstacle thresholds can consist of any devices that can move perpendicular to the roadway.
  • the obstacle threshold can also consist of a plurality of tongues which are arranged next to one another transversely to the direction of travel and can be extended or removed through corresponding openings in the pavement. If these openings are sufficiently small, in the case of retractable tongues the obstacle threshold with their tongues may be below the road level in the idle state, while in the case of retractable tongues the level of the road surface in the area of the openings must be below the normal road level.
  • This solution initially has the advantage that a motorist who drives at an adapted speed does not have to drive over obstacles and is therefore not forced to brake or accelerate. Noise and environmental pollution decrease, the flow of traffic is not obstructed, damage to the vehicle is excluded and ambulances can transport the seriously ill and injured painlessly. If the speed is too fast, on the other hand, the obstacle thresholds that are above or below road level cause the driver to slow down.
  • the obstacle threshold and its guidance in the roadway are preferably designed such that a self-locking effect occurs between them when they are passed over. This has the advantage that the obstacle threshold is locked in its current position when it is passed over, whereas it can easily slide back into the road without any load. It is expediently provided that the obstacle threshold and its guidance have such a geometry and / or surface condition that the self-locking effect only occurs above a certain minimum increase in the obstacle threshold.
  • the triggering threshold in the rest position is movable above the roadway level and is coupled to the obstacle threshold via a mechanical power transmission as an actuating device, the mechanical power transmission preferably having play and / or elasticity corresponding to the distance between the roadway level and the resting level of the triggering threshold.
  • a purely mechanical transmission of power offers the advantage of working independently of energy, the play or the elasticity being necessary in order to prevent damage while simultaneously depressing the trigger and obstacle threshold.
  • the power transmission has two abutting surfaces arranged with play to one another for the impact transmission of a pulse of the triggering threshold to the obstacle threshold.
  • this embodiment ensures that the obstacle threshold is raised as a function of the speed, since the pulse of the triggering threshold depends on the speed when driving over.
  • the trigger and obstacle thresholds are depressed statically, the force transmission is relieved of the contact forces of the vehicle.
  • the bumps can represent a noise nuisance, speed-proportional or progressive damper elements are expediently arranged between the bump surfaces.
  • the triggering threshold is connected to the obstacle threshold via a hydraulic power transmission as an actuating device, a transmitter cylinder being coupled to the triggering threshold and a slave cylinder being coupled to the obstacle threshold.
  • the hydraulic power transmission has a bypass bore with a specific cross section to an overflow tank.
  • This bypass hole has the function of relieving the hydraulic pressure from the pressure exerted by the vehicle while simultaneously loading the trigger and obstacle threshold.
  • the return movement of the obstacle threshold is damped in its starting position.
  • the obstacle threshold is consequently raised by crossing the triggering threshold and then slides back slowly and slowly back into the starting position, so that it protrudes further into the road at higher speed of the vehicle at the moment of crossing than at low speed.
  • the return movement is expediently to be coordinated such that the obstacle threshold in the following vehicles is again in its starting position.
  • the obstacle threshold can be accelerated loosely but without play by the power transmission perpendicular to the road.
  • the obstacle threshold lies below the roadway and moves through its inertia up to the roadway level, the damped reset mechanism mentioned above also being able to be used here.
  • the bypass bore can be dispensed with in this catapult-like device.
  • there is no impulse transmission by impact which reduces the noise pollution.
  • the object is achieved according to the invention in that the obstacle threshold is arranged so that it can be easily folded away at road level, and can be locked for a certain period of time when the triggering threshold is exceeded at excessive speed by means of the actuating device.
  • This alternative embodiment offers the advantage that the masses to be moved are small in the arrangement.
  • the obstacle threshold is normally locked at road level, and can be unlocked by the actuating device for a certain period of time when the triggering threshold is exceeded and can be lowered to a certain level by the vehicle weight.
  • the masses to be moved by the actuating device are also small in this alternative embodiment. If one assumes that heavier vehicles generally have a larger tire diameter than small, light vehicles, a further advantage of this third embodiment alternative becomes apparent. Since the obstacle threshold is lowered more heavily in heavier vehicles, the advantage that large vehicles have due to their larger tire diameter when crossing thresholds is offset. This ensures that the obstacle threshold is as effective for heavy vehicles as for small cars.
  • a trigger threshold 14 is arranged at one end of a trigger rocker 16, the other end of which forms a counterweight 18.
  • the trigger rocker 16 is suspended on a first bearing axis so that the counterweight 18 lifts the trigger threshold 14 through a suitable opening 24 in the road surface.
  • the geometry of the opening is provided so that the triggering threshold can only be lowered slightly below the road surface, even with a small tire diameter.
  • a suspension 22 transmits the forces transmitted from the rocker 16 to the first bearing axis 20 to the housing 12. In the embodiment shown, the suspension is suspended from the upper side of the housing 12, which also represents the road surface, wherein a suspension at other housing points is also conceivable.
  • an obstacle threshold 26 is also arranged on a second rocker 28.
  • This second rocker 28 is suspended from the housing via supports 30 and a second axis 32.
  • the obstacle threshold 26 lies in the rest position with its upper side aligned with the roadway level in a guide opening 34 and is fastened to the second rocker 28 via a tilting axis 36 so that it can be tilted in the direction of travel in the raised state.
  • the rear surface 38 in the direction of travel is designed such that when the obstacle threshold 26 is loaded in the raised, tilted state by the wheel weight of a passing vehicle, a self-locking of the obstacle threshold occurs in the guide opening 34.
  • the friction properties of the rear side of the obstacle threshold 26 and of the rear surface 38 are of importance here.
  • the curved design of the rear surface 38 additionally results in a progressive reinforcement of the self-locking effect with additional ones Raising the obstacle threshold 26.
  • the guide opening 34 can also be designed in such a way that the obstacle threshold 26 can only be tilted above a certain minimum elevation and consequently only then can a self-locking effect occur.
  • the delay in self-locking can also be achieved in that the friction properties of the rear surface 38 differ in different zones, so that the obstacle threshold only lies above the minimum increase in the rough area of the rear surface.
  • An alternative to generating self-locking is to make the obstacle threshold 26 deformable so that it jams in its guide opening 34 under the influence of the vehicle weight. By means of a corresponding geometric design of the guide opening 34 and / or the threshold, it could also be brought about here that the self-locking effect only occurs above a certain minimum increase in the obstacle threshold 26.
  • Driving over the triggering threshold 14 causes the system of counterweight 18, rocker 16 and triggering threshold 14 to receive an angular momentum about the first bearing axis 20.
  • the level of the transmitted pulse is a direct measure of the level at which the obstacle threshold 26 rises from the road.
  • the distance between the trigger threshold and the obstacle threshold should not be too large, in order not to risk false tripping by following vehicles.
  • the geometry of the suspension points, the masses of the system and the damping of the return movement of the obstacle threshold are coordinated so that when the vehicle passes over the threshold arrangement at just the permissible speed, the obstacle threshold has just dropped back to the road level when it is reached by the vehicle. If the vehicle travels at an even higher speed, the obstacle threshold, as described above, rises above the roadway level on the one hand, and on the other hand the vehicle reaches the obstacle threshold more quickly, so that there is less time for its return movement.
  • an additional "maternity zone" can be created for the driver, so that the obstacle threshold 26 is noticeable but slightly unpleasant if the permissible maximum speed is slightly exceeded Has consequences.
  • the play between the abutment surfaces 40 and 42 ensures that the power transmission is not loaded when, for example, a truck with one axle in each case depresses the trigger and obstacle threshold at the same time.
  • FIG. 2 shows a street threshold arrangement 110 in a housing 112 that is flush with the road surface.
  • a triggering threshold 114 is arranged at one end of a rocker 116 which is suspended rotatably about a first axis 120.
  • a counterweight 118 on the side of the rocker opposite the triggering threshold 114 ensures its return movement into the starting position.
  • An obstacle threshold 126 is arranged to be movable about a tilt axis 136 on a lever 128, which in turn is guided about a second axis 132. As in FIG. 1, the obstacle threshold 126 is mounted in a guide opening 134 with a curved rear face 138 in such a way that a self-locking effect occurs in the raised and loaded state of the obstacle threshold.
  • a tension spring 130 is arranged below the obstacle threshold 126 on the guide lever 128 and ensures the return movement of the obstacle threshold.
  • the system comprising the trigger threshold 114, rocker 116 and counterweight 118 receives an angular momentum which is transmitted to the obstacle threshold when a thrust surface 140 hits the counterweight onto a second thrust surface 142 on the underside of the guide lever 128.
  • FIGS. 1 and 2 show clearly that a multiplicity of further variants with varied suspension points, different restoring forces introduced into the system and different positions of the abutting surfaces are possible.
  • FIG. 3 shows a road threshold arrangement 210 with a hydraulic power transmission which, like the mechanical exemplary embodiments described above, is likewise integrated in a housing 212.
  • a trigger threshold 214 is connected directly to the piston of a master cylinder 216.
  • the master cylinder 216 is coupled to a slave cylinder 220 via a hydraulic line 218.
  • An obstacle threshold 222 is connected directly to a piston 224 in the slave cylinder 220.
  • the obstacle threshold 222 movable about a tilt axis 226, is mounted in an opening 228 in such a way that when the obstacle threshold 222 is in a raised position and the obstacle threshold is loaded by a passing vehicle, a self-locking effect between the obstacle threshold 222 and a curved rear 230 Leadership 228 occurs.
  • Depressing the trigger threshold 214 thus results in an immediate lifting of the obstacle threshold 222, wherein a bypass opening (not shown) to an overflow tank (also not shown) enables pressure relief of the hydraulics in the event that the trigger threshold 214 and obstacle threshold 222 are simultaneously lifted by the weight of a vehicle.
  • an alternate lane (not shown) for two-wheelers is preferably provided in order to avert possible dangers from the cyclists or motorcyclists, for example from cars overtaking at excessive speed.
