Definitions
- the invention relates to a rail vehicle with a force-introducing arrangement.
- Rail vehicles are mounted on bogies, by means of which the guidance of the rail vehicles in the track as well as the transmission of the occurring forces takes place.
- the trolleys with the associated wheels are each designed for specified wheel loads, i.e. if the wheel loads are exceeded there is a risk of damage to the trolleys and thus a risk to passengers.
- chassis are usually loaded differently in terms of weight.
- trolleys normally have a lower wheel load and power units usually have a high wheel load.
- the rail vehicles themselves are becoming increasingly heavier (more electrics, higher load design, heavier components or new or additionally introduced, heavy components, such as air conditioning systems, etc.), while at the same time the wheel load specifications for the chassis remain constant because the Otherwise, the chassis would have to be redesigned in a complex and therefore expensive manner. As a result, it becomes more and more difficult to comply with the corresponding wheel load specifications over time.
- a rail vehicle consisting of at least a first and a second car, which can be coupled to one another by means of an articulated connection
- the first and the second car above the articulated connection with an active force-applying arrangement are connected to one another in such a way that by means of the active force-applying arrangement Arrangement exerted a force on the first and second carriages who can.
- the articulated connection is usually attached close to the floor or rail.
- the solution according to the invention has the advantage that the respective connection of two rail vehicle cars with an active force-bringing arrangement by means of leverage relieves the respective chassis or its wheels and the corresponding forces are distributed to the surrounding chassis and their wheels are thus loaded.
- corresponding, heavy components can be installed in the positions suitable for these components, while at the same time continuing to use standard running gear previously used, with maximum utilization of the respective specified wheel loads. In this way, complex and expensive new designs of the chassis and the resulting additional costs can be avoided.
- heavy rail vehicles can accordingly also be operated in infrastructures where only low wheel loads are permitted.
- a pressure or a tensile force is exerted on the carriages connected to one another by the force-applying arrangement.
- the force exerted by the force-applying arrangement is adjustable.
- the force required can be adapted exactly to the local conditions of the rail vehicle. Should the corresponding conditions change over time, this can be taken into account at any time and the force can be readjusted accordingly.
- the force-applying arrangement is possible in both a compact, one-piece and a multi-part design, consisting of separate individual components that can be connected to one another.
- the active force-applying arrangement has at least one force-applying component and a force control unit, which can be connected to one another.
- the force on the two cars connected to one another is exerted by the force-applying component, and the force exerted is regulated by means of the force control unit.
- the force-generating arrangement can be distributed better in terms of both space and weight, and it is also easier to maintain.
- the force exerted by the force-applying arrangement can be adjusted by means of the force regulating unit.
- the set force is automatically monitored by the force control unit and kept at the set value. This reduces the corresponding maintenance or adjustment effort and a change to the set force is usually only necessary if it has to be adapted to changed local conditions, for example by changing or shifting weight by changing the technical equipment of the rail vehicle in question.
- the force control unit is located on the roof of one of the respective cars, which are connected to a force-applying arrangement, each in the vicinity of the force-applying component. This makes it particularly easy to build.
- the force-applying component of the force-applying arrangement connects the connected cars to each other in the roof area.
- the distance between the force-applying component and the articulated connection near the floor or rail, with which the two cars are coupled to one another is as large as possible, which also optimizes the leverage effect on the chassis concerned with regard to the more even distribution of the wheel loads.
- the force-applying component of the force-applying arrangement preferably has at least one pneumatic cylinder. This has the advantage that comparatively high forces can be achieved in a small installation space. Furthermore, pneumatic systems are robust against overload and insensitive to temperature fluctuations. Furthermore, leaks in the system do not cause any environmental pollution from escaping fluid, only energy losses occur.
- the force control unit of the force-applying arrangement particularly preferably has a compressor which can be connected to the force-applying component, for example a pneumatic cylinder, in order to advantageously regulate the pneumatic pressure, in particular to set, monitor and maintain it.
- the compressor is advantageously located on the roof of one of the cars that are connected to a force-applying arrangement, in each case in the vicinity of the force-applying arrangement, in order to be able to realize the shortest possible connections.
- the central compressed air system of the vehicle which can be connected to the force-applying component, could also serve as the force control unit.
- the force-applying component of the force-applying arrangement advantageously has at least one hydraulic cylinder.
- the advantage of this design is that when required, in comparison to pneumatic systems, higher forces can be achieved very easily and this can also be achieved in a small installation space.
- hydraulic systems have a high level of positioning accuracy.
- the service life is very long, with low maintenance at the same time thanks to the self-lubrication of the sliding parts by the hydraulic fluid.
- FIG. 1 shows a rail vehicle consisting of several cars with a force-applying arrangement
- a rail vehicle (1) is an example of several cars (2, 3, 4, 5, 6, 7) with a Krafteinbrin ing arrangement (30), by means of which two cars (4, 5) each Weil in the area the roof of the car (4, 5) in question are interconnected.
- the rail vehicle shown consists alternately of carriages (2, 4, 6) with chassis (10, 12, 14) under the car (2, 4, 6) and carriage (3, 5, 7) without chassis.
- a force (F), for example a compressive force, can be applied in the longitudinal direction by means of a force-applying arrangement (30) according to the invention, with which the two carriages concerned (4, 5) are connected to one another in the roof area of the carriages (4, 5) of the rail vehicle (1) on the two carriages (4,
- the force-applying arrangement (30) is shown schematically in FIG. It is preferably designed in a multi-part construction, consisting of separate individual components that can be connected to one another, the alternative embodiments of which are shown and described in detail in or to FIGS. 2, 3 and 4. By dividing it into several individual components, the force-introducing arrangement (30) can be better distributed over the carriages (4, 5) of the rail vehicle (1) both spatially and in terms of weight, and it can also be more easily maintained.
- additional force-applying arrangements (60, 70), for further carriages (2, 3) or (6, 7) can be attached, which support the force-applying arrangement (30) by correspondingly additional pressure or tensile forces exerted and thus optimize the distribution of the wheel loads on the chassis (10, 12, 14) of the rail vehicle (1).
- additional force-applying arrangements (30, 60, 70) with regard to the
- Fig. 2 shows a force-applying arrangement (30) in a multi-part design, consisting of force-applying components (32) and force control unit (34), which are connected to each other.
- the component that applies the force is a pneumatic cylinder (32) which is connected to a force control unit, in this case a compressor (34).
- the compressor (34) is arranged on the roof of one of the respective wagons (5), which are connected to the force-introducing arrangement (30), and in the vicinity of the pneumatic cylinder (32) to keep connections as short as possible to be able to realize.
- the force (F) on the two The car (4, 5) connected to one another is exerted by the pneumatic cylinder (32) and the exerted force (F) is regulated by means of pneumatic pressure by the compressor (34), i.e. in particular set and automatically monitored and the set value maintained.
- the power-introducing arrangement (30) shown here as a pneumatic system, is robust against overload, insensitive to temperature fluctuations and does not cause environmental pollution by leaking fluid in the event of leaks.
- FIG. 3 shows an alternative force-applying arrangement (40) with a hydraulic cylinder (42) as the force-applying component and a compressor (44) suitable for hydraulic systems as a force-regulating unit, which are connected to one another.
- the corresponding compressor (44) is located on the roof of one of the respective carriages (5) which are connected to the force-applying arrangement (40) and in the vicinity of the hydraulic cylinder (42) in order to be able to construct the shortest possible connections.
- the force (F) on the two carriages (4, 5) connected to one another is exerted analogously by the hydraulic cylinder (42) and the exerted force (F) is regulated by means of hydraulic pressure by the compressor (44), i.e.
