B. Yapalaparvi Department of Electrical and Electronics Engineering Department of Mechanical Engineering Hirasugar Institute of Technology, Nidasoshi, Karnataka Hirasugar Institute of Technology, Nidasoshi, Karnataka (India) (India) Abstract The wheelchair is one of the most commonly used assistive devices for enhancing personal mobility, which is a precondition for enjoying human rights and living in dignity and assists people with disabilities to become more productive members of their communities. For many people, an appropriate, well-designed and well-fitted wheelchair can be the first step towards inclusion and participation in society. When the need is not met, people with disabilities are isolated and do not have access to the same opportunities as others within their own communities. Providing wheelchairs that are fit for the purpose not only enhances mobility but begins a process of opening up a world of education, work and social life [1]. The development of national policies and increased training opportunities in the design, production and supply of wheelchairs are essential next steps. Every human being need to move from one place another to fulfill his requirements and to accomplish that requirements he will travel from one place to another place by walking which is a basic medium of transportation. But it is exceptional in case of physically disables (Persons don’t have both legs). In order to support and help such a person’s we designed a special manually lever operated wheel chair.

  • Design and Modification of Bicycle by Using Additional Sprockets
    Vol-3 Issue-4 2017 IJARIIE-ISSN(O)-2395-4396 DESIGN AND MODIFICATION OF BICYCLE BY USING ADDITIONAL SPROCKETS Sanjeey Reddy K Hudgikar1 S.M.Saleemuddin2 1 Professor, Mechanical Department, Lingaraj Appa Engineering College,Bidar,Karnataka,India 2 Assistant Professor, Mechanical Department, Annamachara Institute of Technology & Sciences,Rajampet,Kadapa,AP. ABSTRACT Biking is increasingly being recognized as a highly sustainable form of transportation. The present work focus on design and development of bi-cycle which can be implemented as an alternative to the two wheelers consuming large amount of fuel and polluting the environment. To overcome these problems, an effort is being made to search some other for the vehicles. Again, it is also not affordable to purchase vehicles (mopeds, scooters or motorcycles) for all the class of society. Keeping this in mind, a search for some way to cater these economically poor people as well as to provide a solution for the environmental pollution was in progress. This work deals with these problems efficiently as energy is generated utilizing the mechanical energy of the rider. Keyword: - Sprockets, Welding, Gear Mechanism 1. INTRODUCTION A bicycle, often called a bike or cycle, is a human-powered, pedal-driven and single-track vehicle having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist or bicyclist. Bicycles were introduced in the 19th century in Europe and as of 2003, more than 1 billion have been produced worldwide twice as many as the number of automobiles that have been produced. They are the principal means of transportation in many regions.

  • How Automatic Transmissions Work
    How Automatic Transmissions Work If you have ever driven a car with an automatic transmission, then you know that there are two big differences between an automatic transmission and a manual transmission: • There is no clutch pedal in an automatic transmission car. • There is no gear shift in an automatic transmission car. Once you put the transmission into drive, everything else is automatic. Both the automatic transmission (plus its torque converter) and a manual transmission (with its clutch) accomplish exactly the same thing, but they do it in totally different ways. It turns out that the way an automatic transmission does it is absolutely amazing! Location of the automatic transmission In this article, we'll work our way through an automatic transmission. We'll start with the key to the whole system: planetary gearsets. Then we'll see how the transmission is put together, learn how the controls work and discuss some of the intricacies involved in controlling a transmission. Some Basics Just like that of a manual transmission, the automatic transmission's primary job is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds. Photo courtesy DaimlerChrysler Mercedes-Benz CLK, automatic transmission, cut-away model Without a transmission, cars would be limited to one gear ratio, and that ratio would have to be selected to allow the car to travel at the desired top speed. If you wanted a top speed of 80 mph, then the gear ratio would be similar to third gear in most manual transmission cars.

Karlekar Department Head Prof. '"egible Signature Prof. Ray C. Johnson DEPARTMENT OF MECHANICAL ENGINEERING ROCHESTER INSTITUTE OF TECHNOLOGY ROCHESTER, NHJ YORK August 1983 A CONSTANT FORCE BICYCLE TRANSMISSION ABSTRACT A prototype design for a human powered automatic transmission intended for use on an ordinary touring bicycle is presented. The transmission is intended to automatically adjust the gearing of the bicycle to maintain an optimum pedal force, regardless of the current riding conditions. Therefore, the transmission eliminates the need for the cyclist to manually adjust the bicycle gearing. The entire transmission is a self-contained unit designed to bolt onto the rear wheel of an otherwise unmodified 27-inch bicycle. The transmission combines a unique adaptation of a commercially popular continuously variable traction drive with a totally mechanical integral feedback controller. The features of the traction drive unique to its application to a bicycle are outlined in detail, along with an analysis of the important traction drive design parameters.

    IJRET: International Journal of Research in Engineering and Technology eISSN: 2319-1163 | pISSN: 2321-7308 AUTOMATIC TRANSMISSION GEARBOX WITH CENTRIFUGAL CLUTCHES Suraj S Raut1, D.P.Mali2 1Department of Mechanical Engineering, Sou. Venutai Chavan Polytechnic, Pune, India 2Department of Mechanical Engineering, Sou. Venutai Chavan Polytechnic, Pune, India Abstract The various developments in the automobile field are going on increasing; hence we have also tried to modify the transmission system of light weight vehicles such as motorbikes for simplicity in driving the vehicle in an efficient way. The disclosure herein is concerned with an automatic transmission gearbox with centrifugal clutches which operates automatically as engine speed (RPM) goes on increasing. In this work we have designed and manufactured the automatic gearbox model which consists of gear assembly with three different gear ratios and centrifugal clutches of various spring tensions, which driven by electric motor. This gearbox overcomes disadvantages of Continuous variable Transmission (CVT) system by replacing belt and pulleys with centrifugal clutches and gear assembly, which is more compact and avoids loss of power when operating at high speed. Also it is light in weight, efficient, reliable, less time consuming and economical of manufacturing.
