FINAL YEAR PROJECTS FOR YOU: January 2015

ABSTRACT:

The Suitcase car is a type of mini car designed for one person and can carry a load up to 80 kg. Its unloaded weight is up to 30 kg. It can be packed into a suitcase and can be lifted by any person.

For this we learned the fundamentals of Strength of Material for calculation of load, stresses and forces acting on various parts of chassis of our car. To select the type of drive we studied Machine Design and choose chain drive which is best suited for the requirements. For the type of Engine we go through Automobile Engineering and selected two stroke engines due to its small size and good load carrying capacity.

Disassembling is the secondary issue for which we used detachable tires and folded handle. There are so many difficulties arise in placing fuel tank and driver seat. After all we used various ideas used small size fuel tank and driver seat.

The innovation in this project is to produce an economically viable and affordable car for mass so that it can carry load and can travel smoothly on Indian roads.

INTRODUCTION:

As the population is increasing there is also increasing in demand of the automobiles. Due to the increasing number of automobiles they will require space for driving and also for parking. As we know there is limited space available. Due to the increasing number of cars on roads they cause traffic jam and also they acquired a place for parking. As the number of cars is increasing the pollution also increases. The Portable Car (Suitcase Car) is a foldable car which can be folded in a suitcase; hence it does not require the parking place. The size of the Portable Car is 46”x 22” so it is five times smaller than normal car. Due to its compactness it can be used in various big shopping malls, industries, big campus of college etc. Portable car can be used in shopping malls, industries and for covering short distance. It can be used for travelling purpose on the highways.

It was originally designed & built in 1991 as part of a design contest held at Mazda's Engineering department which was created with a simple idea to have a 3-wheeled car inside a suitcase. Instead of waiting in line for a taxi or shuttle, just open your suitcase & drive off.

Powered by a 59.57cc 2 stroke engine, the vehicle holds enough fuel approximately 2 hours of driving. Can be assembled in about 15-20 seconds & comes with functional brake lights & turn signals. Vehicle was rebuilt in a black suitcase in 1994. But as suitcase car is running on the two stroke engine with the 27 mph that suitcase car can run for 2 hours with the fully filled fuel tank due to the use of engine it can cause pollution and noise.

In order to overcome above mentioned disadvantages in the present invention we used the motor and battery instead of engine. Portable Car can be assemble and dissemble whenever necessary and also we can carry suitcase anywhere and if necessary we can assemble it in just less than four minute and drive it. In this portable car we used four wheels out of that the power is given one wheel and other wheels are supporting wheel.

If there is no use of car then we can just simply dissemble the car& put it in to the suitcase. The portable car can carry weight up to 100kg. Maximum speed of portable car is 30 km/hr. fully charged battery can run up to 70km.

OBJECTIVE & SCOPE:

Transforming the car was simple:

· Open the suitcase

· Attach rear wheels

· Raise and lock steering column

· Flip up the lights

· Pull to start

Some of the major advantages of Mini cars are as follows:

· The cost of maintenance is affordable.

· The small size and light-weight make it easy to park Mini cars.

· Mini cars are so light that they can be lifted by hand for parking.

· Mini cars possessed forward entry which helped in perpendicular parking.

Suitcase car is something different to the above concept. It is suitable only for the clean and smooth roads. We can use this car in college campus, school campus, office campus, at airports, on cruise etc. Beside this, Suitcase car also have a bigger advantage that it can be folded and packed into a suitcase. These advantages facilitate a person to carry the car through his journey. Suitcase car is designed for a single person that can sustain the load of an average person. It is a light- weight vehicle. All the parts of the suitcase car are mounted inside a suitcase.

Technically

· A suitcase of large height can be used to increase the space.

· Large tire can be used.

· Weight of the suitcase can be reduced by using fiber body suitcase.

· It can be powered by a high capacity engine having the same size.

· A CVT can be used to optimize its speed.

· Differential can be used for high speed and better control.

· Secondary systems like lighting, horn, speedometer etc. can be attached.

· An option of self start can be installed.

According to its usage

· It can be used as a racing car.

· It can be used on cruise to travel from one point to other.

· It can be carried while traveling by train, bus, plane etc.

· It can be used in college campus, school campus, university campus, etc.

· It can be used in a society.

· It can be used for entertainment purpose.

DESIGN :

Parts to design are as follows:-

· Body casing

· Chassis

· Front wheel (Directly purchased from market)

· Rear wheel (Directly purchased from market).

· Handle with Accelerator arrangement.

· ROD Pinion arrangement for driving power from Engine to wheels.

BODY CASING:

It is the main part of our project. It consist of a large Suitcase made up of ballistic nylon material.

BODY CHASSIS:

A chassis is the physical frame or structure of Briefcase car. This is design in such a way to sustain and carry all components.

FRONT WHEEL:

In this suitcase car, we have made it rear wheel drive as it is a three wheeler. We have provided a tubeless tire which is used in children’s bicycles.

REAR WHEEL:

There can be two possibility first it would be unbalancing had it been simply one tire each on either side, front and rear, so basically it is to balance the weight of passengers and that of driver and at the same time the mass of the tires (that of two rear and one frontal) should be nearly equal as this will also work towards or help in balancing process.

HANDLE WITH ACCELERATOR ARRANGEMENT:

The handle of this car id designed in such a way that it is detachable and it can be folded and fitted inside the casing of suitcase

ROD PINION ARRANGEMENT:

WIRING AND LIGHTING:

An open circuit is simply a switch that is off, a break in a wire, or a burned-out bulb. Open circuits are usually caused by breaks in the wiring, faulty connections, or mechanical failure in a switch or component. They cause components to fail, but they do not cause fuses to "blow."

Fuses act as safety valves for electricity by pre- venting damage caused by short circuits and over- loads. If a short or overload causes the circuit's current drain to exceed the amp rating of the fuse, the fuse "blows" and switches off the current to that circuit. All fuses are contained in the fuse block, which is located on the inside of the fire wall, usually on the driver's side. It is labeled with the name of the circuit (s) each fuse protects and, in most cases, the amp rating of the correct fuse.

A short circuit occurs when electricity finds a short cut" from positive to negative; it is the result of a bare spot on the wire contacting part of the metal car body. The windings in electric motors can also short. Short circuits are hazardous be- cause they create sparks, burned wires, and blown fuses

Two-light systems have one headlight on each side, each of which has a high-beam and a low- beam filament. Four-light systems have two lights on each side; two of them should be lit for low beam and all four for high beam

CONCLUSION:

Suitcase car is our main project that is presented in front of you. In present day we are studying the chases and load analysis that is use in it. On the first stage of my project, we are going to show to you theoretically portion of it.

We are very glad to show to you some fraction of our live work in this project. There are some issue that arise during live work but we have shoot it out by discussing to each other and with fraction of effort of my faculty members
