Starting with an IHS market analysis, we’ve covered a wide range of current developments on your behalf in the field of transmissions and drives. In this issue well-known manufacturers and suppliers talk about their latest electrification concepts, but also about new developments in conventional transmissions and individual drive components in terms of efficiency, performance and costs. The latest insights in development methods and drive component production are another key topic, with contributions from AVL, Getrag, GKN, BorgWarner, Oerlikon and many more besides. To give you the bigger picture, we also interviewed high-calibre experts from the automobile industry. Read for yourself what Hyundai’s John Juriga has to say about full and plug-in HEVs for the medium segment, and how Eaton’s Jeff Carpenter answers the latest questions on DCT. And for everyone who was there (and those who couldn’t make it), we’ve included a follow-up report on our recent CTI Symposium China too. Our special thanks to everyone who helped to make this issue happen. Happy reading! Your CTI Mag Team PS: The eighth issue of CTI Mag will be published in May 2017.

But what are the implications for transmissions, and the transmission market, as governments, OEMs, suppliers and customers all strive for lower CO� emissions/fuel costs? Chris Guile, Principal Analyst, IHS Automotive Introduction From a technical perspective, there is a broad range of possible have much higher volumes to consider, but for these applications configurations for OEMs and suppliers to consider, when thinking conventional transmission technologies will be used, in most cases. about vehicle electrification. Whilst we cannot evaluate all of these possibilities in such a short article, what we can do is look at some of Usually, an additional sensor is all that is required to confirm when the the broader market trends which are emerging, during this ‘embryonic’ transmission is in neutral, for the stop-start operation.

Let us start by looking at the implications for the different manuals also need some way to maintain oil pressure, usually in the types of electrified vehicle: form of an electric oil pump, or an oil storage system. Manual transmissions will also be offered on mild hybrids, particular in Europe, Electric Vehicles some of which will switch to e-clutches. For Electric Vehicles (EVs), there are many simple reduction transmissions/systems, which are available for the OEMs to use. With so much investment in the existing supply chain and production However, the volumes for EVs are not expected to represent a equipment, leading to high levels of inertia, this slow ‘evolution’ of an significant share of the global market (see graph below). In this respect existing technology is a story we have seen many times, in the they do not yet pose a threat to the existing transmission suppliers/ automotive industry. supply chain. Having said that, the high torques available from electric motors are making EVs increasingly attractive to customers, for Full Hybrids sporty/ performance applications. For the moment, most of these But the most interesting question arises when we consider the full vehicles use single-speed transmissions, but IHS Automotive does hybrids. Despite their current low share, this is an important part of the expect multi-speed transmissions to be used in the future. market, and involves much more complex powertrain systems which always require some kind of transmission. Stop-Start/Mild Hybrids At the other end of the electrification spectrum we have the stop-start For the full hybrids, OEMs have to ask themselves: ‘Should we retain vehicles, and the slightly more complicated mild hybrids.

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.

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.

  • Direct Shift Gear Transmission
    3International Conference on Ideas, Impact and Innovation in Mechanical Engineering (ICIIIME 2017) ISSN: 2321-8169 Volume: 5 Issue: 6 180 – 184 _______________________________________________________________________________________________ Direct Shift Gear Transmission Mr. Pranav Rathi1,Prof. A. J. Patil2 1Student, Department of Mechanical Engineering, Smt. Kashibai Navale College of Engineering, [email protected] 2Professor, Department of Mechanical Engineering, Smt. Kashibai Navale College of Engineering, [email protected] ABSTRACT The Direct Shift Gear Transmission (DSG) also known as Dual Clutch Transmission(DCT) or twin-clutch transmission, is an automated transmission that can change gears faster than any other geared transmission. Dual clutch transmissions deliver more power and better control than a traditional automatic transmission and faster performance than a manual transmission.Modern DSG automatic gearboxes use a pair of clutches in place of a single unit to help you change gear faster than a traditional manual or automatic alternative. Cars with DSG gearboxes don’t feature a clutch pedal and are controlled in exactly the same way as a conventional automatic. Direct Shift Gear transmission (DSG) also called as Dual Clutch Transmissions (DCTs) are providing the full shift comfort of traditional step automatics but offer significantly improved full efficiency and performance. Fuel efficiency increased by 15% compared to planetary-ATs, the DCTs are the first automatics to provide better values than manual transmissions.

Assistant Professor, Dept. of EEE, Mar Baselios Institute of Technology and Science, Nellimattom, Kerala, India 5. ABSTRACT: Automated Manual Transmission (AMT) is an electro-hydraulic mechanism for automating the manual transmission systems present in the vehicles. Currently, most of the vehicles on road have manual transmission systems, in which the controlling of the vehicle, in every way is done by the user. In technical terms, the driver of the vehicle must manually press the clutch pedal, in order to change the gear and ultimately change the speed of the vehicle. And this is a very tiresome process in heavy traffics and of course causes great discomfort. Here is the relevance of AMT where the clutch controls and gear shifting is fully automated. AMT is already implemented in some cars like that of Ferrari and Maruti, but not in two wheelers due to the bulky size of hydraulic parts. In our proposed system, we try to develop an AMT system for two wheelers fully based on an electronic control unit, which intakes the values from different units like rpm sensing, speed sensing, clutch control, gear sensing units etc.
