Description

DETAILED DESCRIPTION OF THE INVENTION In the following, a track bus track means a running surface delimited on both sides by edges. This edge serves as a guide surface for a so-called lateral guidance bus. This bus is a vehicle equipped with rubber tires and guide rollers with vertical axes in front of the front wheels. The guide roller is guided while rolling along the guide surface, and obtains steering information for laterally guiding the vehicle. The entry area and departure area of the orbital bus route are as follows. This is the area where the lateral guiding edges begin to form, where the normal road space ends, and where the designated travel path, which is exclusively for rail buses, begins or ends. A passenger vehicle is a vehicle with a shorter wheelbase and lower ground clearance than an orbital bus. Therefore, it also includes small buses and other vehicles whose chassis size is approximately the same as that of a passenger car.

Running a vehicle without manually steered guide rollers on a track bus track is extremely difficult when moving forward, and difficult when moving backwards due to the narrow width of the track between the guide surfaces. Almost impossible. In contrast, a tracked lotus can travel very quickly, safely and comfortably on a track, assuming that it is not obstructed by vehicles that are not equipped for track guided driving. That is, it is necessary to prevent vehicles that are not suitable for track guided operation from entering the track lotus travel path.

This is usually avoided by appropriate traffic control, eg signs, signals, markings, etc.

However, it once again happens that drivers of passenger cars, out of sporting ambitions or because of a desire for a quick and unhindered drive, ignore traffic control and deliberately drive into the track lane. This seriously disrupts regular rail bus traffic and is dangerous.

Naturally, the inner door of a railroad crossing or such a structure can be considered as an entry prevention device. But they have moving parts that are prone to failure, especially in winter, and can be a hindrance to traffic. Furthermore, it is necessary to supply energy to this prevention device.

SUMMARY OF THE INVENTION The object of the invention is to design a trespassing prevention device in such a way as to prevent the use of a bus track by passenger cars without the need for special monitoring and control measures. At that time, a passenger car attempting to enter the bus route despite the prohibition is allowed to do so without causing damage to the vehicle or its passengers.
It should be able to survive this attempt as much as possible, and in particular be able to escape backwards again and clear the bus track again without external help.

This problem is solved according to the invention by the features of patent claim 1. Obstacles according to the invention can be formed in various ways.

i The running surface is provided with a particularly rectangular central recess. Therefore, the lower wheel of a vehicle guided by the track has a large wheelbase, so there is sufficient running surface outside the recess, but passenger cars have a narrow wheelbase, so it is difficult to enter the track bus route through the recess. blocked by.

ii. A barrier is provided in the center of the running track that projects from the running surface. This barrier allows orbital buses with large wheelbases and high ground clearance to pass, but is an impassable obstacle for passenger cars.

1ii The two entry obstacles can be used together.

The recess in the center of the running surface is preferably formed in such a way that it connects to the running surface via a ramp.

The barrier can be formed from an elastic material, such as rubber, but also hard materials, such as sheet steel or wood, may be used. In this case, the barrier is preferably provided with a predetermined breaking point so that it deflects when a large force is applied.

It is expedient if the vertical surface extending transversely to the direction of travel and facing away from the entry or exit side or the corresponding surface of the barrier is provided with traffic light-colored paint and/or warning lights.

Furthermore, the edges between the running track and the recess on both sides of the barrier are chamfered flat to a depth of about 2 to 5 inches according to the invention.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the figures.

FIG. 1 is a schematic plan view of a entry point on a track lotus track equipped with an entry prevention device. Cross sections of the running road in front and behind the entry point are shown in Figures 1A and 1B. The running surface 1 of the running path is delimited on each side by one guide element 2 . This guide member is provided for laterally guiding the track lotus. The guide rollers of the orbital bus move on the guide member (see FIG. 2). In this embodiment, the entry prevention device consists of a combination of a recess 3 and a barrier 4. However, both obstacles can be used alternatively. The barrier 4 is formed as follows. That is,
The orbital bus is able to pass through the barrier 4 due to its high ground clearance, but the barrier 4 is formed so that it becomes an impassable obstacle for passenger cars. The barrier is preferably an elastic material,
For example, it is made of rubber or of a hard material, such as sheet steel or wood. In this case, a predetermined failure point is provided, so that when a large force is applied, the barrier deforms. A surface 5 of the recess 3 facing the entry side and perpendicular to the direction of travel and a surface 6 of the barrier corresponding to this surface are painted with traffic light color paint to improve visibility. ,and/
Or equipped with warning lights.

The left side of FIG. 2 shows the half of the rail bus with the front axle on the tamper-proof device, and the right side shows the half of the rail bus with the rear axle on the tamper-proof device.

It can be seen that both the front and rear axles of the bus are able to pass through the trespassing device. At this time, the wheels pass along the sides of the recess 3. In the case of a rear axle with double tires, only the outer tire runs on the running surface. However, this is not a problem at all since the flat running surface allows shock-free running. At that time, the outer tire is subjected to a large load, so it is deformed to some extent, but the inner tire is not under any load, so the tension is removed (entspan).
(nen) Due to the difference in the levels of the inner and outer tires, the side edges (the first (see Figure 1) is chamfered flat by approximately 2 to 5 cm. The upper edge of the barrier 4 must be formed as follows. That is, the vehicle chassis must be designed so that the ground clearance is sufficient to pass through the barrier even when the tires are not inflated.

FIG. 3.4 shows a cross section and a longitudinal section of the left half of a passenger car that has entered the center of the entry prevention device. The vehicle still has some space on the side, and in front the bumper abuts the end face or barrier of the recess. The front wheels are in the recess 3 and cannot ride forward from the recess, such as when driving over a curb. Since the bottom surface of the recess is formed obliquely like a ramp in range 8,
Connected to the running surface again. Therefore, a passenger car that has fallen into the recess can escape from the recess by retreating under its own force. This is extremely important. This is because without this ramp, the vehicle can only escape using a crane or the like.

This leads to disruption of regular orbital bus traffic.
