DE4028544A1 - Energy saving passenger transport system - uses electrically powered car for short distances and train for long distance - Google Patents

Abstract

The passenger transport system reduces reliance on fossil sources of energy and also reduces the amt. of CO2 which is discharged to the atmos. It combines road and rail transport. An electric car is used for transport to and from the station. The passengers' luggage is packed in a case to facilitate its transfer from car to train. The journey from the railway station closest to the destination is completed in a second electric car to which the luggage is transferred. USE/ADVANTAGE - Passenger transport which saves energy and reduces environmental pollution.

Description

The energy and raw material consumption of today's private transport and the resulting CO₂ emissions seem below Consideration of the climate problems in the near future no longer to be portable. The currently available public transport means i. d. R. a much lower energy consumption, but can the important distribution function of the automobile at close range is not almost take over. Luggage can also be transported public transport is nowhere near as flexible and be designed as comfortably as with the automobile. Just think For example, a family's vacation trip and their luggage or to the brochure folders, samples, documents to be carried etc. of a sales representative.

To get the clear and undeniable benefits of Individual traffic with the advantage of less Energy consumption and lately also the advantage of extreme to combine high travel speeds of rail vehicles, the following combined transport system is proposed.

The automobiles intended for the transport system (see Figure 1) have a standardized luggage container that can be removed at the top and is housed in the bow. The vehicles have a generous amount of space for approx. 5 people, as well as for the luggage carried (luggage container approx. 500 ltr. Content).

An automobile is used for short-haul routes in cities proposed that consistently in terms of drive and chassis a speed of max. 50 km / h is designed. Hereby it is possible to change the vehicle weight and drive with one Optimizing the internal combustion engine so that fuel consumption of about 1 liter / 100 km and below should be achievable. For a vehicle for close urban areas with a max. An electric drive is of course also a speed of 50 km / h conceivable and possible. The variant with an electric motor enables this Use of CO₂-free energy sources, such as electricity generation Nuclear energy, hydropower, wind and solar energy etc. These Energy sources remain largely in today's private transport closed due to the high demand for storage energy for long-distance transport. Long-distance transport, in particular, is used for this proposed system carried out rail-bound.

An automobile is used for the medium range up to approx. 100 km proposed that also in terms of drive and chassis consistently at a speed of max. 80 km / h is optimized and has a fuel consumption of approx. 1-3 liters / 100 km. For these vehicles would also come in an electric drive in the future Consider.  

Standardization is only for the proposed automobiles with regard to the requirements for a fully automatic loading and Unloading the luggage containers and stacking the vehicles in the proposed high-bay warehouse at the station is necessary. The vehicles are therefore not necessarily "Standard vehicles", but it is conceivable, as with one usual car rental today, very different brands to offer different equipment and looks. It is also conceivable, if desired, that the vehicle be owned of the user remains.

For a long-distance trip, the closest one is for this system designed station approached with the named automobile and the Called destination station. After leaving the automobile, it is moved with floor conveyors or the like. transported to the unloading station for the luggage containers. Here the luggage container becomes automatic, for example with a Suction lifter, lifted out, for a certain train with others Containers put together and after the arrival of the train from a loading machine into a special container wagon that the Carrying the train, loading it. The whole process should be done with the help of modern Conveying techniques such as those used in warehouse technology today can be applied in less than 10 minutes. The car is taken from one of the luggage containers Conveyor system taken over, in a high-bay warehouse (such as already carried out for the city of Singapore) available here for arriving passengers.

Vehicle check, consumption determination, etc. can largely be automated. The accrued consumption and rental costs could be automatically through a customer account or credit card system be handled.

The personal luggage container will be back at the destination station combined a vehicle from the high-bay warehouse there and is then ready for passengers to continue.

It is also conceivable that a permanent in short-distance traffic used vehicle remains in the possession of the user The high-bay warehouse of the train station only turns off and at the destination then lends a vehicle to a long-distance trip for the duration of the trip.

The proposed combined transport system continues to offer the advantage that it is gradually competing with the existing one Private transport could be introduced and used and none Sole claim. In the simplest case, the Equipping a railway line with two stations is sufficient.  

Advantages of the system

- Consumption of fossil fuels for passenger transport can be reduced by an order of magnitude
- Use of CO₂-free energy sources is also possible at close range thanks to the electric drive of relatively slow-moving vehicles (50 km / h)
- No need for highways or highways for this system
- Less space used for traffic routes and parking spaces
- Drastic decrease in emissions caused by automobiles
- Vehicles can be made compact despite the generous amount of space, since a larger vehicle height in the lower speed range does not play an important role
- Offers the automotive industry the opportunity to offer a closed overall transport system together with railways

Disadvantages of the system

- Required expansion of rail transport
- Loss of individuality in long-distance transport
- No driving pleasure due to high speeds in local traffic
- Missing identification with vehicle
- Problems to be expected when the activities of the automobile manufacturers are shifted to the proposed system
- Possibly. Standardization problems at European level
