Maximum Transmission

Throughout the world's automotive industry, a great deal of thought is currently being directed towards achieving power transmission layouts which are both compact and weight-saving and which achieve the desired distribution of vehicle weight. This trend is particularly noticeable in Europe, where success in the market place depends to a large extent on giving greatest passenger space for the customer's money. However, it was on a very non-European passenger car that a product was introduced which is now helping designers obtain maximum transmission compactness at minimum cost. The car was the Oldsmobile Toronado, and the product the Morse Hy-Vo® inverted tooth chain.

Contactless electrical energy transmission (CEET) system realizes power transmission with no electrical or physical connection by the perfect combination of inductive coupling technique and electronics. This paper studies the characteristics of the CEET system based on the loosely coupled transformer mathematical model, then analyses the power transmission performance and its changing rules in different compensation topologies. We can get the parameter requirements when the load obtains the maximum transmission power from these studies. This work can provide reference to optimize the circuit design and promote the power transmission ability for the CEET system.

State Of Art

In the past several years, there has been increased market place awareness of noise, vibration, and harshness performance in automobiles. The differentiation between the quality and reliability levels of automobiles has become less pronounced and, as a result, manufacturers have had to demonstrate superiority by focusing on NVH concerns. The automotive industry is currently spending millions of dollars on NVH work to develop new materials and damping techniques so that the damping treatments are lighter, cheaper, and more effective. Some of the methods used to control noise, vibration, and harshness includes the use of different carpeting treatments, the addition of rubber or asphalt material to car panels, gap sealant, and the injection of expandable foam into body panels. The aim of this study is to explore the feasibility of smart damping materials such as magnet orheological elastomers (MRE), piezoelectric materials, with its basic properties, for augmenting and improving the performance benefits of damping materials. This study also evaluates the noise and vibration benefits of smart damping materials as compared to conventional damping treatments.

The first half of the seventies of the 20th century was the time of great changes in Poland. The new leadership of the Central Committee of the Polish United Workers’ Party, headed by First Secretary Edward Gierek, reformulated the party policy, trying to improve the living conditions of the society and at the same time, to modernize the Polish industry, to enhance residential construction, and to boost international trade. The Polish automotive industry also required radical changes in the vehicles of both, private use and collective transport. Hence, at the beginning of 1971, a politically-motivated decision was made to buy a license for a small-engine car and for a modern bus from the western countries. The trade negotiations with Fiat, Citroën, Renault (passenger car) as well as Berliet, Fiat, Hino (Japan), Klöckner-Humboldt-Deutz (bus) did not last long. Already in October 1971, a contract was signed with the Italian Fiat, under the terms of which the Fiat 126p car production was to be launched in Poland, and in August 1972 with the French Berliet, which undertook the production of a modern bus. In practice, Fiat 126p took the national automotive industry to a totally new level, becoming a highly popular car. The Berliet bus, in contrast, proved not to be an effective solution to the problems of the Polish public transport. It can be concluded that the concept of modernizing the Polish automotive industry by launching the licensed production of Western vehicles, which was formulated at the beginning of the seventies of the 20th century, turned out to be only partially successful.

We present the design and fabrication of metamaterials, and investigated the power transmission properties of the metamaterials in the frequency ranging from 1.04THz to 4.25THz. The measured results reveal a global maximum transmission peak at 2.52THz. We compared measured power transmission performances of four types of metamaterials microstructures, and analyzed their transmission differences.

Regarding front-wheel drive passenger car, because of the limit of power transmission system space, a torque converter was developed to the flat shape. In this paper, a leaned blade flat torque converter was developed with an increasingly narrower torus's profile for the purpose of achieving a smaller axial size. It is composed of a pump having a leaned pump blade, a turbine having a leaned turbine blade and a stator, and the flatness ratio is 0.21. The core of the pump blade's inlet and outlet is opposite separately in the shell and moves 1/3 cascade spacing along the pump's hand of rotation. The core of the turbine blade's inlet and outlet is opposite separately in the shell along the turbine revolving and go astern 1/3 cascade spacing. The computational results indicate that the torque ratio decreases slightly but the torus is more flat when the blade is leaned. And the capacity factor decreases, the nominal torque improves, it may use the small effective diameter to satisfy the match request of passenger car with the same engine power, and it has more vital practical significance to solve the question of front-wheel drive layout's limit.

In today's highly competitive global market place the pressure on organizations to find new ways to create and deliver value to the customers grows ever stronger. There have been many new ideas and concepts in business management over the last thirty or so years, some of which have endured and others discarded. However, perhaps one of the most significant principles to become widely adopted and practiced is that of just in time, or JIT. It is a philosophy as much, as it is a technique; it is based upon the simple idea that wherever possible no activity should take place in the system until there is a need for it. With increasing pressures on profits, due to the launch of several new models, with marginal differences in prices, Indian Automotive companies would do well to move towards JIT purchasing systems. Given the extent and variety of constraints and the existing purchasing mindset in Indian Automotive industry, it'will take some more time to understand and practice the technique. This paper attempts to understand the possibilities of implementing JIT technique in the Indian automotive industry. This will help the automotive component manufacturers to effectively formulate their marketing strategies to create value to their OEM customers. It also helps the vehicle manufacturers to be competitive in the end market.
