Button Operated Electromagnetic Gear Shifting System in Two Wheeler

There are disclosed an electromagnetic Type Gear Change System control apparatus for an automobile and a method of controlling such apparatus. A rotational output of an internal combustion engine is connected to drive wheels of the automobile and a load device. When a gear shifting-up of a electromagnetic type transmission is to be effected, the load applied by the load device is increased, or the load is connected to an output rotation shaft of the engine via a selectively-connecting device, thereby reducing the rotational speed of the output rotation shaft of the engine to a required level. In our project, two electromagnetic coils are coupled to the gear rod of the two ends. The two Buttons are used to activate the electro-magnetic coil so that the gear will be shifted. In this project, we aim at developing easy gear shifting mechanism for transmission which will make motor bike rider’s gear shifting very easy. Everyone desires for the smooth running of the vehicle whatsoever may be the speed of pickup of the vehicle a person is operating, but one of the most important systems which every engineer is concerned about in vehicle is gear shifting system for ensuring smooth and desired ride on their two wheelers. Some simple mechanism is arranged solenoid plunger which will help us to change the gear as per the desired torque. In this gear shifting mechanism, gear shifting is done with the help of two solenoid plungers. The up shifting and downshifting of gears is done with the help two independent switches. These two switches are connected to solenoid plungers via battery.

Experimental Research of Transmissions on Electric Vehicles’ Energy Consumption

The growth of electric vehicles share of total passenger-vehicle sales is evident and is expected to be a very big market segment by 2030. Range of travel and pricing are the most influencing factors that affect their gain in market share. As so, powertrain development is a key technology factor researched by the automotive industry. To explore, among others, how the energy consumption of zero emission vehicles is affected by different transmissions, we developed, built and installed a variety of them on a custom hydrogen fuel cell powered urban vehicle. In this work we present a comparison of the effect, on the energy consumption of the proposed testbed, of a prototype custom build 2-speed gearbox and a single stage transmission. Results presented show a reduction of the overall energy consumption with the use of the 2-speed gearbox, compared to single stage, as well as the effect of gear change speed, related to speed, in energy consumption. Finally, a correlation of experimental results using a custom build CVT is conducted compared to single stage transmission. A comparison to simulation results found in literature is performed for all the transmissions tested on road.

Analysis of composition of linear acceleration body structure of vehicle during the gear changing

The article presents and discusses the results of vibration measurements of a commercial vehicle body during a gear change. Data obtained during road tests were analyzed in the frequency domain and evaluated for the vibration intensity index affecting the human body.

Multistage Mechanical Transmissions with Automatic Control for Advanced Trucks and Buses

The study considers the basic trends of development of modern mechanical transmissions of trucks and buses. It provides the developed various series of multispeed transmissions with automatic control and a number of transmissions from 6 to 16 for trucks and buses. The paper shows the basic parameters of the standard series of new transmissions received on the basis of innovative technical solutions. It provides the results of experimental studies of 16-speed transmissions on a special test stand and on the road as part of a truck transmission. Theoretical and experimental data on the gear change time are compared.

In Search of a Way

This chapter explores ecumenical methodology. It is organized in six sections. The first reflects on ecumenism as a ‘method’, a ‘way’, variously understood, about which there is a second-order methodological discourse concerning how it is best pursued. The second reflects on the variant approaches of ‘Life and Work’ ecumenism and ‘Faith and Order’ ecumenism. The third assesses some of the strategies which have hitherto been important in bilateral dialogue and identifies the need now for an ecumenical gear-change. The fourth section pursues this idea by focusing on a strategy which has come to be referred to as ‘receptive ecumenism’. Following an exploration of the methodological implications of this strategy in relation to bilateral dialogues in the fifth section, the sixth section finally explores its implications at the level of the local church.
