Introduction: Solar Powered Reverse Trike

SOLAR POWERED REVERSE TRIKE

Designed and built in just 18 days at the University of Engineering and Technology Lahore in Pakistan,  7 x 3.5 x 4.5 ft (2.13 x 1.06 x 1.37 meter), 132 pound (60 kg) low-rider features a custom built, t-shaped aluminum framework at the front of the vehicle, and the back part of an old bicycle frame at the rear, joined just behind the seating area to shock absorbers. The reverse three-wheeler - with two wheels at the front and one at the rear - also has a 40 watt photovoltaic canopy above the rider that charges the onboard 12v/80Ah dry cell solar battery.

An eco-friendly vehicle that uses solar energy as its source of input. A solar panel is used to charge the battery and the battery drives the dc motor.
Its a vehicle that uses reverse trike configuration, i-e two front wheels and a single wheel on the rear side. Steering is done with the help of front wheels. It also consists of a solar panel, Battery and a dc motor.

Step 1: 3D Design of the Vehicle

First of all i made the 3D design of the vehicle in Solid Edge v20. Below are the picture of the vehicle.
This was a vital step in fabrication of the vehicle. So without considering any other thing i made the 3D Model of the Vehicle to give a proper look!....

Step 2: Chassis Fabrication

After the 3D design of the vehicle was completed i stated the fabrication of the Chassis. I used Aluminum rectangular Sections 2"x1", thickness 2mm for chassis main body. For welding the aluminum rods together i used the Argon welding!..... It took around 4hours to get welded with exact dimensions.

Step 3: Bicycle Rear Section


I used a rear section of the bicyle to hold the rear wheels.... which was later used to drive the vehicle!

Step 4: Front and Rear Chassis Assembly

Next step was to assemble the fabricated front part of the chassis with the rear section taken from a used bicycle! U-shaped bar was used to hold the parts together!.... then comes the shock absorber which was attached to two angle iron bars....

Step 5: Wheels Mounting

Next step was to mount the wheels on the vehicle....

Step 6: Steering Mechanism


Since this a reverse trike so front two tires were to be used for steering ...... so i used T-joint mechanism to steer the wheels!....

Step 7: Motor and Battery Placing

A small frame was made to support both the motor and the battery, using angle irons....

Step 8: Solar Panel Mounting

To mount the solar panel on the top of the vehicle a frame was to be designed as in 3D model.... so finally it was welded on the base of the chassis

Step 9: Charge Controller Circuit Diagram

Purpose of the charge controller circuit is to cutoff the supply from the solar panel when the battery is fully charged to avoid over charging... and to start charging when battery voltage drops off a certain value... in my case the max. allowed voltage is 13.7volts and min is 13volts.

Step 10: Solaron! Ready in ~550USD "RESULTS"

And finally an other addition to Green Technology! and after series of experiments i conclude the following results

RESULTS

1. It can go upto 30kmph max. speed.
2. Covers a max distance of 70km in one full charge (without panel)
3. No air and sound pollution.
4. Renewable energy source, no external power required.
5. Automatically charges the battery.

The+Mak3rs made it!(author)2011-08-25

thanks you so much .... well i just bought it from the local electronic store... its called "Charge Regulator or controller" also called "Cut-off circuit" well it consists of a relay and resistors and IC (dont know the specs) but its purpose is to cutt-off the supply from the Solar panel when batteries are fully charged in my case utt-off voltage was 13.9 Volts

DOES IT HAVE A SPEEDOMETER OR ELSE HOW DO YOU KNOW THAT IT TRAVELS AT A SPEED OF 30 MILES PER HOUR?

author
The+Mak3rs made it!(author)2011-08-25

ok firstly i would like to ask you where are you from?... secondly its 30kmph not mph.... and lastly no it does not have a speed-o-meter, yet we can measure its speed!... HOW?.... well we had motor bikes which traveled along with the vehicle .... and they had speedometer!... hope you understand the rest .... cheers

Hi Farrukh,

1. If we want to use the same technology and use it as rickshaw / cart to carry construction material, or vegetables, or waste material, how much weight it can carry with present battery.

2. Suppose if we want to carry material of 250-300kg as solar powered rickshaw.

3. Incase during winter or rainy days, when no solar energy, can we charge the battery through electricity (as as back-up charge). Some solar water heaters come up with both option, solar charge & water can be heated through electric connection also.

Regards,
Amit
