Rail cum road vehicles (RCRV) and economy rail track-cum-corrugated concrete track to engage with corrugated tread rubber wheels on all roadways.

Abstract

A rail cum road vehicle(RCRV) running on rail tracks or on plain roads, includes a gas powered hybrid engine coach linked to and pulling one or several passenger coaches or goods vehicles, all of which in common are fitted with pneumatic rubber wheels, steel wheels, air suspension system with hanger brackets, air brakes and couplers. The air suspension system will lift the axles of the rubber wheels for rail travel, and it will lift the steel wheels to nm on plain roads. Its regenerative braking system produces electricity to run the motor of an air compressor unit or the vehicle itself. The engine power is transmitted to the steel wheels and the rubber wheels via crown / differential boxes and sprockets and chains. All of the RCRV are fitted with ‘advanced light weight rail tracks brakes’ and ‘corrugated concrete track to engage with the corrugated tread rubber wheels’ for instant braking. The circular chassis bogie at rear end helps the RCRV on tracks and on road comfortably negotiate. The ballast-less economy rail track with lesser numbers of light weight sleepers is bolted to the ground for comfortable journey with less noise.

AI Technical Summary

Benefits of technology

The present invention provides a device called "rail-cum-road hybrid engine coach" that can run on both rail track and plain road. It contains a hybrid engine with a trailer-cum-semi trailer / passenger coach / caravan / ambulance. The device has a front axle with rubber wheels and steel wheels, and a rear axle with rubber wheels and steel wheels. The front axle has a steering mechanism and can run on rail track or plain road. The device has a rail track-cum-concrete corrugated track and a circular bogie for smooth movements on both rail track and plain road. The device also has an air suspension system for better control and stability on both road surfaces. The invention improves the air suspension system by preserving more high-pressure air and using it for braking and inflating air bags. The device also has a gas engine at the front for power and a link gear box for efficient transmission of power.

Problems solved by technology

But unfortunately the existing railways could not accommodate more passenger coaches or wagons, as they already reached a saturation point.

The main problem with Railways is the high construction cost of their rail tracks.

So, all developing and poor countries could not afford to spend for such costly rail net work.

Also, so far, there was no any alternative economic rail transport technology like RCRV available to the public throughout world.

Regarding freight movement also, either rail or road transportation did not at all satisfy people.

There is enormous delay and theft in rail transport.

So, they seriously warn that the existing world-wide transport net work may collapse and the mankind has to face the aftermath doom and gloom.

When such is the present world's burning crisis, no attempts of any kind have so far been made to revolutionize the heavy, costly, slow moving and obsolete TRAMS / Street rail cars and the killer road vehicles.

But unfortunately all the embodiments of their inventions had been found to be deficient in technologies and unsafe to run on rail tracks as detailed below:

Cumbersome equipments to lift and lower the axles with rubber wheels and steel wheels, then complicated construction of guides to place the vehicle on rail track from plain road, then fitting motors to rubber wheels to move along rail track, without applying mind how the motor will run the vehicle on plain roads without electricity and then other embodiments were orientated with the existing heavy railway bogies.

Therefore roadways commercial vehicles may not suit for broad gauge rail track.

In another dangerous embodiment, both steel wheels and rubber wheels were designed to bear and share the vehicle load equally while running fast, may lead to derailment and more consumption of fuel due to continuous friction / adhesion of rubber wheels on its road track; in another embodiment, convex steel wheels had been designed to run on concave rails and vice versa.

This system will lead to derailment as the natural oscillating tendency of running trains due to wind force and deflection of rails in between sleepers will damage such wheels and rails, which cannot be prevented.

But there was no fool-proof technology applied to safeguard the vehicle while crossing at points of “NO-RAIL’ level crossings and other railway crossings where the larger dia rubber wheels need sufficient space or guide to pass through.

This is a very very critical issue.

Still, there will encounter another big problem i.e. the larger dia rubber wheels cover more distance than the smaller dia steel wheels as both are fitted on the same axle.

So when the idly rotating lifted larger dia rubber wheels suddenly lowered and made to take the entire load and run on ramp, it will create a sudden and violent JERK to the entire train leading to imbalance, disturbing passengers.

Further, this kind of frequent disturbances will damage the couplings and joints and rubber wheels may also burst.

Then comes another problem; while the larger dia rubber wheels cross other existing rail tracks, what type of guide was designed, has also not been disclosed; then while moving from loop line to main line and vice versa the same problem encounters and there was no solution explained in those embodiments.

Though the design was simple, fitting and removal of rubber wheels was a laborious job.

So it would be fatal if there was no precision braking system in the R.C.R.Vs.

That was why the heavy TRAMS / street rail cars move very slowly because of its obsolete design and ineffective braking system throughout world.

Therefore all the related prior arts could not succeed to commercialize their patents in the absence of safety, comforts, speed, simplicity, economy and eco-friendliness.
