in their efforts to develop basic informative and instructive material for analysis and design of

SUITCASE CAR. This report has been written as a part of the program of minor project as

fulfilment of the requirement of KURUKSHETRA UNIVERSITY

Writing a report of technical aspects is indeed a very challenging task. The students have to

possess not only expertise in the subject matter but also the technique of selecting appropriate

material from the vast fund of knowledge they have regarding the subject of project and

present it in a way which the reader can easily understand. Judging from remarks of the

experts who reviewed the report and also on the basis of earlier projects by these students in

mechanical field. I have no doubt in my mind that they had done excellent job.

The institute will therefore fell amply rewarded if the other students and teachers may go

through this report for enlarging their knowledge of SUITCASE CAR. Any suggestions for

the improvement of this project and the report from all quarters will be most welcome.

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 tyres 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

A car is a wheeled, self-powered motor vehicle used for transportation. Most definitions of

the term specify that cars are designed to run primarily on roads, to have seating for one to

eight people, to typically have four wheels, and to be constructed principally for the transport

of people rather than goods. The year 1886 is regarded as the birth year of the modern car. In

that year, German inventor Karl Benz built the Benz Patent-Motorwagen. Cars did not

become widely available until the early 20th century. One of the first cars that was accessible

to the masses was the 1908 Model T, an American car manufactured by the Ford Motor

Company. Cars were rapidly adopted in the United States of America, where they

replaced animal-drawn carriages and carts, but took much longer to be accepted in Western

Europe and other less-developed parts of the world.

Cars are equipped with controls used for driving, parking, and passenger comfort and safety.

New controls have also been added to vehicles, making them more complex. Examples

include air conditioning, navigation systems, and in car entertainment. Most cars in use today

are propelled by an internal combustion engine, fueled by deflagration of gasoline (also

known as petrol) or diesel. Both fuels cause air pollution and are also blamed for contributing

to climate change and global warming. Vehicles using alternative fuels such

as ethanol flexible-fuel vehicles and natural gas vehicles are also gaining popularity in some

countries.

CLASSIFICATION OF SMALL CARS

MICRO-CARS

Straddling the boundary between car and motorbike, these vehicles have engines under 1.0

litre, typically seat only two passengers, and are sometimes unorthodox in construction. Some

micro-cars are three-wheelers, while the majority have four wheels. Micro-cars were popular

in post-war Europe, where their appearance led them to be called "Bubble cars". More recent

micro-cars are often electric powered.

Examples of micro-cars:

Isetta

REVA

Tata Nano

ULTRA-COMPACT CAR

In 2012, Japan's Transport and Tourism Ministry will allow local government to use ultra-

compact cars as transport for residents and tourists in their limiting areas. The size of ultra-

compact cars will be less than mini-cars, but have engine greater than 50cc displacement and

able to transport 1 or 2 persons. Ultra-compact cars cannot use mini-cars standard, because of

strict safety standards for mini-cars. The regulation about running capacity and safety

performance of ultra-compact cars will be published in early autumn. Today, there are cars

smaller than ultra-compact cars, called category-1 motorized vehicles which it has 50cc

displacement or less and only one seat for the driver.

11

SUITCASE CAR

The idea is simply 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 58cc 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. It is built around a small steel

chassis and is steered by handlebars. It also includes head lamps for night time driving and

functional brake lights and indicators to warn other road users of your actions. If you need

additional safety features, maybe it’s best that you stick to cars that can’t be folded up and carried.

With 2.4 horsepower 58cc two stroke engine, it is comfortably the slowest vehicle we have

featured yet.

TRANSFORMATION OF THE CAR IS SO SIMPLE

Open the suitcase

Attach rear wheals

Raise and lock steering column

Pull and start

OBJECTIVES & SCOPE

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.

13

Technically

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

Large tyre can be used.

Weight of the suitcase can be reduced by using fibre 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 travelling 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 DESCRIPTION

Suitcase car is powered by a two stroke single cylinder gasoline engine. The engine capacity

is 49 cc and using an air cooling system. The power output of the engine is 2.5kw at 8700

rpm which is delivered to the rear axle using a chain drive mechanism. The engine has a pull

type starting mechanism that is operated manually. By this output the car can be travel at a

speed of 40 Km/hr.

All the parts of the suitcase car are mounted inside a suitcase. The car consists of the two

halves that are joined by the nut and bolt to make a rigid structure. The rear half contain the

engine which is connected to the rear axle by a chain drive. The rear axle contains to

detachable parts one is main shaft and other one is tyre shaft. Both shafts are coupled by

cotter joint. Main axle shaft is hollow and is lifted on four bearings. Wheels are 8” in size and

made up of rubber. Roller bearings are used to transmit the load on the chassis of the car. On

the main shaft seat is connected. Seat is made up of fiber and light in weight.

The front half of the chassis contains the handle which is used to give direction to the vehicle.

The front wheel is 6” in size and contains a centre bearing. The handle is linked to the

member of the chassis such that it can trace a rotating motion. The handle contains an

excluded part which supports the foot load of the rider. The whole suitcase is divided into

three compartments so that in one compartment contains the detachable tyres, the second one

contains the handle and seat and the third one contains the transmission system and engine.

The suitcase car is designed and built for use on a paved closed circuit track. The track should

be clean and without obstacles of any kind. It takes hardly 3-4 minutes to install. An adult or

younger person can drive it. It is suitable for campus purpose.

BODY

A body (sometimes referred to as "coachwork"), which is usually not necessary for

integrity of the structure, is built on the chassis to complete the vehicle.

We have used suitcase for the body of our project.

17

Types of bodies

Shell forming the exterior of a car.

Hatchback: two-door passenger compartment with a door at the back.

Sports car: small,two-seated automobile.

Four-door sedan: passenger compartment with four doors and four side windows.

Limousine: large, six-seated passenger compartment.

Convertible: car with a removable roof.

Hardtop: two-door passenger compartment.

Van: small vehicle used to carry baggage; a small van.

Pick-up truck: a small truck.

CHASSIS

A chassis consists of an internal framework that supports a manmade object in its

construction and use. It is analogous to an animal's skeleton. An example of a chassis is

the under part of a motor vehicle, consisting of the frame (on which the body is mounted).

If the running gear such as wheels and transmission, and sometimes even the driver's seat,

are included, then the assembly is described as a rolling chassis.

In the case of vehicles, the term rolling chassis means the frame plus the "running gear"

like engine, transmission, drive shaft, differential, and suspension.

ENGINE

An engine, or motor, is a machine designed to convert one form of energy into mechanical

energy. Heat engines, including internal combustion engines and external combustion

engines (such as steam engines) burn a fuel to create heat, which then creates a force. Electric

motors convert electrical energy into mechanical motion, pneumatic motors use compressed

air and others—such as clockwork motors in wind-up toys—use elastic energy. In biological

systems, molecular motors, like myosins in muscles, use chemical energy to create forces and

eventually motion.

"Engine" was originally a term for any mechanical device that converts force into motion.

In modern usage, the term engine typically describes devices, like steam engines and internal

combustion engines, that burn or otherwise consume fuel to perform mechanical work by

exerting a torque or linear force (usually in the form of thrust). Examples of engines which

exert a torque include the familiar automobile gasoline and diesel engines, as well as turbo-

shafts.

The first commercially successful automobile, created by Karl Benz, added to the interest in

light and powerful engines. The lightweight petrol internal combustion engine, operating on a

four-stroke Otto cycle, has been the most successful for light automobiles, while the more

efficient Diesel engine is used for trucks and buses. However, in recent years, turbo Diesel

engines have become increasingly popular, especially outside of the United States, even for

quite small cars.

25

We have used a CHAIN SAW engine of 2 stroke, 58 cc to power the vehicle.

Engine — almost always a two-stroke gasoline (petrol) internal combustion engine, usually

with a cylinder volume of 30–120 cm3 or an electric motor.

Drive mechanism — typically a centrifugal clutch and sprocket.

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 used in it. On the first stage of our project, we

are going to show you theoretical 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 some nearby mechanical workers.

But it is not the folding car ever made, but that is a story for another day.
