Abstract

The vehicle has a system for braking wheels driven at variable speed.

Description

Motor vehicle adapted to the railway lines.

Description and justification

It is a removable vehicle, very light weight (approx. 150 Kg) and that reaches a maximum speed of 20 km / h., Given the end for which it has been conceived, this moderate speed prevents any accident risk, even in the case of derailment, the vehicle stops immediately, and given its Easy handling it is simple to place it back in your lane.

It is designed to transport 6 to 8 people or their weight equivalent, although this number can be increased in those cases that the tourist route is clear of obstacles, even you can adapt some other vehicle attached to the motor vehicle, as long as it does not go into the category of heavy vehicle, since would lose its fundamental characteristic, this is to be manageable by one or two people to turn the vehicle around and get on track or  change places without having to disassemble it.

Object

As the name implies, it is an adapted motor vehicle to travel on railways and more specifically, for unused railway traffic, for tourism purposes with which it is intended to discover areas of great beauty for which in his day trains circulated and that today are in total abandonment (with a lot of weeds and all kinds of obstacles) what it makes circulation impossible with other mechanisms; good that they demand greater effort as is the case of those who perform the transfer by pedals or in the case of vehicles to heavier engine, with which you run the risk of derailment, either by vegetation or by concealment of roads, produced by lands or landslides that would make very difficult to place it again on the rails, to the point if required, if necessary, a crane.

This vehicle, given its characteristics, is prepared for drive on roads with vegetation and partial or level crossings fully covered.

For the description of the vehicle a series of figures are attached in which, with an illustrative and non-limiting nature, it is represented The object of the invention.

Preferred Embodiment of the Invention

A description of the invention based on the following is made. in the previously commented figures.

The motor vehicle (1) adapted to the railway lines consists first of a platform (2) in which they leave adapting the rest of the parts and mechanisms so you can adapt to the width of the road through which it is going to circulate and time is propelled by an engine (3) with gearbox (4), to vary the speed and even change the direction of travel (reverse).

On the platform (2) two front axles (5) are adapted by a system of screws and nuts (6). These axes carry Built-in braking system (7) by drum with shoes which are activated by steel cable (8) and brake pedal (9). On these axes both front wheels (10) are placed by screws (19) that rotate freely, as they are attached to the drum (7) and which in turn is adapted to the shaft by means of bearings. These wheels (10) are attached to the rim by screws and nuts (11) 8 mm guide plates (12). thick, which makes the vehicle does not derail and adapts perfectly to the lane, although is partially covered, since said guide plate (12) makes its mark on the ground and keeps on track.

The wheels (10) can be of the same type used in the cars with a rubber case to avoid punctures in areas in which the road is full of brambles or thorns. To avoid this inconvenient you can use metal wheels of the type used on railroad cars or the same wheels as cars but previously solid, with the consequent increase of weight that makes you lose your manageability.

Once the front wheels are mounted, the system is connected braking (13), by means of tensioners (14) with nuts self-locking, adapting to the brake pedal (9) found subject to the platform (2).

At the rear of the platform (2) two axes are adapted rear (15) by two bearings (16) on each axle, subject to the platform using screws and nuts (17), so you can turn freely once connected to the drive system. In one of the ends of said axes (15), which has a disk shape (18), are adapt the rear wheels (10), using screws (19), and that they are the same type as the front wheels and were already described above, and at the other end that is shaped like a vessel (20) and It is hollow for the shafts (21) of the gearbox (4) to enter of the motor system.

Once the rear axles (15) are mounted, the system must be mounted drive, consisting of a motor (3) connected to a gearbox (4) from which two perforated shafts (21) come out, which are connected to the rear wheel axles (15) by means of two pins (22). This drive system is attached to the platform (2) by screws and nuts (23).

Once these operations are finished, we can start the  vehicle (1) on the rails (33), but to be able to transport people in a comfortable and safe way, you have to install the seat supports (24) (25) that are secured by bolts and nuts (26) to U-shaped profiles (29) that they are welded to the platform (2) and on these supports are place the plastic seats (25) using threaded knobs to the four studs that each seat carries. For this case concrete is a motor vehicle for 6 seats, so 3 supports (24) will be installed and on these supports will be placed 2 seats in each. If necessary, they can be deleted any support except the rear support, since on it install the clutch (27) and throttle (28) system cables motor

To complete the assembly, a protector (30) of light and resistant material, as a shield, to avoid the impacts of existing vegetation (brambles, thorns, branches, etc.) In said protector it has been adapted in the a high part (31) connected to the electric motor generator, to illuminate tunnels or to travel at night.

To start the vehicle, the engine is started and once placed the first gear through the lever (32), it acts with the clutch (27) that makes the gearbox work changes (4) that will transmit the movement to the axes and therefore to the vehicle itself.

To get more or less speed you can vary the gear, using the gear lever (32) and the throttle (28). In case there is also a reverse gear, although to change the direction of travel is better to turn the vehicle, reason why which is necessary to be manageable to be able to do this type of operations.

A speed meter can be adapted to the rear wheels, to know at all times at what speed it circulates, as well as The distance traveled.

Claims (5)

1. Motor vehicle adapted to the railway lines that is characterized in that it consists of a platform where the axles are adapted, according to the track width, on which the wheels that are moved by a driving system, composed of a engine and a gearbox that provide a variable and safe speed. On said platform some supports are adapted to place the seats and make the crossing more comfortable and safe. In this platform, a light, transparent and resistant material cover can be adapted, which can be disassembled depending on the weather. 2. Motor vehicle adapted to the railway lines according to claim 1 characterized in that the wheels are of the type and size of those of the cars, previously protected to avoid punctures, which provide a minimum height to the platform that avoids friction by the existing vegetation in the disused lines of the railroad. These wheels have internally adapted guide plates to the rim, larger in diameter than the wheels, to act as a flange and prevent derailment. 3. Motor vehicle adapted to the railway lines according to previous claims characterized by being removable and easy to handle for easy transport. In said vehicle, and depending on the state of the track and the power of the engine, other platforms can be adapted, like small wagons, towed by the motor vehicle, to increase the transport of people or things. 4. Motor vehicle adapted to the railway lines according to previous claims, characterized in that the material used can be made of light alloys and thus achieve greater manageability of the vehicle. 5. Motor vehicle adapted to the railway lines according to previous claims characterized in that it carries a parapet, as a shield that mimics an old train and prevents vegetation from hitting passengers.
