Description

The invention belongs to the field of the machine part of the service device and the electric-powered means of transport on the road.

BACKGROUND OF THE INVENTION

Public transport of passengers by road is usually provided by buses. For individual transport are used liquid fuel cars, exceptionally electric cars, hybrid cars and means of transport using hydrogen power. The wider use of electric vehicles is prevented in particular by the short range due to the rapid discharge of the carried batteries. In addition to electric vehicles with a central electric motor, a method is known in which electric motors are incorporated into the wheel hubs. This is the case, for example, for lorries in opencast quarries, where electricity is supplied, similar to railways, trams and trolleybuses, from overhead rails above the vehicles in the direction of their travel (US φ9 ^ 41 Al).

For passenger cars, a similar height suspension of the rails is applied in the case of a telescopic frame header (FR 2949 ^) 98 A1).

The lateral deviation of the vehicle travel from the direction of the overhead line electric trolleys is assumed, similarly to the known fairground attractions, by the construction of a contact wire network over the motorway lanes (DE 30 ^ 077A1).

It is also known a device which, in trucks, can be connected to electric overhead trolleys to lock autonomous driving by means of a swiveling two-arm lever with wiper brushes (WO 135 ^ 70 Al)

For positioning of electric trolleys laterally from the direction of travel of the vehicle, the connection to them is designed using a parallelogram carrier (CN 101580021 B)

Electromotive travel units built into electric vehicle swivel bogies allow continuous synchronous wheel speeds as designed (CZ 2CM58 Ul)

Slope of mobile electric units relative to the bogie axis is considered to improve the stability of the electric vehicle (CZ-PV2011-425)

Rail transport operates trains with traction locomotives or separate wagons equipped with liquid fuel or electric propulsion engines, which may be of two sources: for connection to an external power network and alternatively with its own electricity generator. Trains that are supported on a magnetic or air cushion are also known. For railways, electrical energy from the grid is supplied from overhead rails. The subway has a trolley at the side or underside of the train bogies.

SUMMARY OF THE INVENTION

According to the invention, the electrification system for road passenger and delivery transport consists of a complex electromobility, created by electromobile trains and passenger electric vehicles, connected by an accompanying supply network in crash barriers and supplemented with photovoltaic panels.

The subject of the inventions is an electromobile train for driving on the road, consisting of a technological head of the machine and several subsequently suspended passenger cars or vans, the height of which corresponds to passenger cars and the length of buses. Batteries intended to power the traveling units located on the bogie at the end of the wagons are also stored in the total number on the machine. These batteries are alternately recharged with vehicle batteries on the lead machine installed by the generator, or from rails in crash barriers along the road. This solves the problem * «B«

- Sufficient range of the electromobile train. In addition to cable and trolley wiring, supplementary electrical energy is obtained from photovoltaic panels distributed along the road.

Another variant of the invention is the operation of an electromobile train without the use of batteries, the source of electric power for all the running units being a generator on the leading machine, or alternatively an alternative direct power supply of the electric motors by rails in crash barriers.

The invention also provides the possibility of disconnecting the last wagons on the train and their autonomous running by providing a separate control device.

Compared to the current state of passenger transport on roads, the solution according to the invention brings the following advantages:

- Increase the safety of operation by unattended control after connecting electric vehicles to rails in crash barriers, while using known devices for ensuring safe distance of vehicles.

- Energy savings by using additional electricity from photovoltaics.

- Increasing passenger transport capacity through the creation of electromobile trains.

- Improving the throughput of existing roads.

- Greater comfort for public transport passengers.

- Longer road life by eliminating track roll-out due to the lateral movement of the wheels while driving in a curve.

- Use of a single power source to allow the same power and engagement torque of all electric motors of the traveling units at constant speeds and during changes of direction.

- Possibility of gradual disconnection and connection of wagons when turning for separate driving.

- Unmanned connection of trains and electric vehicles to rails in crash barriers by running the pulley on the swing arm on the vertical base of the barrier.

- Unification of the safety function of road barriers with the power supply for electric vehicles.

- Unlimited range, still limited by battery discharge, ensured by continuous charging via a powered generator and connection to an accompanying electrical network.

An embodiment of the invention

Of the individual components of the road transport electrification system, the electromobile train, consisting of the technology manager 1 and passenger cars 2, having the height of a small passenger car and the length of a large bus, is of key importance. In an electro-mobile train there may also be vans of the same dimensions on the same bogie 3. Known bogies 3 are located at the end of each passenger car 2 and also on the leading machine 1. of the rotating bogie 2 and mounted under the gearbox 5 above which the batteries 6 are located. The driving function for changing the direction of travel has the entire passenger car 2, which rotates the driven bogie 3 for bringing the electric motor units 4 in the same direction. The same arrangement with this passive rotation of the chassis 2 is also at the rear of the head machine 1 of the electromobile train. The leading machine 1 has in its front part the same bogie 3, but this is actively controlled by the servomotors 7 in directional and speed control of the electromobile train from the driver's station 8.

The lead machine 1 carries an electric power generator 9 and another set of 10 batteries equal to the total number of batteries 6 in all passenger cars 2. The generator 9 can directly generate electricity for all electromotoric traveling units 4 or alternately recharge the batteries in the car. all passenger cars 2 and a set of 10 batteries in the lead machine 1.

The passenger cars 2 are connected to each other by means of connecting arms 11 fixed in the front of the passenger cars 2 and anchored in the vertical axis of the bogies 3. The passenger cars 2 have in their rear part a sanitary facility 12 and a luggage compartment 13.

In the case where it is necessary to disconnect and reconnect individual coaches 2 from the train for autonomous travel, a flip-off catch 15 is mounted in the trough 14. The trough 14 is pivotally mounted on a pillar 16, at the bottom of which a wheel axle 17 controlled by drive 18 for driving while driving a passenger car 2.

In addition to the generator 9 on the lead machine 1, alternatively, trolleys 19 located in the crash barriers 20 of existing or newly constructed roads can be used as electric power sources. The power to the trolleys 19 is supplied from ground cables 21 or from photovoltaic panels 22 distributed along the road by accumulators 23 housed in shafts below the freezing depth. The activation of the individual sections of the trolley 19 is carried out non-contact by means of transmitters located at the beginning and at the end of the electromobile train.

The connection of the lead machine 1 to the trolleys 19 is effected by one or two hinged beams

24. having a spring-loaded thumb 25 with a pulley 26 and scraper brushes 27 at their free end. The pivot path of the thumb 25 from the point of contact of the pulley 26 to the trough 28 in the crash barrier 20 is delimited by a slot in the tip 29 of the tilting beam 24. only when driving in the arc of the crash barriers 20, in a straight line it is maintained in the center of the trough 28 by the flow of ambient air.

The electric vehicle 30 for individual transport, with a swivel bogie 3 and a tilting beam 24, is expanded at its rear and fitted with a suspension safety wheel 31 at the rear for comfortable seating.
