Hybrid powertrains have been on the market for more than a decade and have become one of the most successful alternative powertrains available today. More than a million hybrids are sold globally per year, primarily in Japan and the US. Some OEMs estimate that up to 80% of their light-duty vehicles may require some level of hybridization to meet upcoming CAFE regulations in the United States. Hybrids are also starting to make inroads into markets in Europe, and have recently been introduced to Chinese and Indian markets, among others. Basic information on hybrids is scattered among information sources, and is often difficult to synthesize.

Continuously Variable Transmission (CVT) technology is both a theoretical and practical option that addresses a number of system level improvement opportunities within the automotive and mobility industries. Although this technology has been available for many years and is now fully matured as a production ready technology, it is often not fully understood. This web seminar presents a focused view of CVT technology in all its forms and implementations.

In India, the market demand for passenger cars with automated manual transmissions is steadily increasing. So far, the most successful vehicles addressing this trend use magnitude as the sales of vehicles with manual transmissions. Since customers are expecting even smoother vehicle operation, the next anticipated step is the move to automatic transmissions without any torque interrupt during gear shift. This can favorably be addressed with the dual clutch transmission technology. Re-utilization of already existing manufacturing facilities is possible with the retention of the lay-shaft design. Dual clutch transmissions offer driving characteristics, including vehicle launch, which are very similar to the behavior of vehicles with manual transmissions. This applies also to the fuel economy. Against this background, this article introduces an all new concept for a very cost efficient dual clutch transmission family for transversal, transaxle powertrains.

Mild-hybridisation of conventional powertrains is set to become commonplace over the next 5 years, providing a proportion of the on-cycle and real-world CO2 benefits of a high-voltage hybrid at a far lower cost. However, the majority of this focus is around engine-related systems such as belt starter-generators and electric-superchargers. Design studies and simulations have shown that hybridising elements of the transmission system can extend the efficiency gains of engine based mild-hybrid and stop-start systems. Equally important, is the potential for a transmission integrated electrical system to support value-adding features such as electric creep, engine-off coasting or electric torque support for manual or automated manual transmissions, which can either further justify or partially offset the additional cost of the hybrid system.

Currently known hybrid systems are technically complex and cost-intensive and referring to this for many end customers not available. Under this boundaries IAV has developed a cost optimal minimal concept of an efficient and modular powertrain platform for electric and hybrid vehicles. The system based on one unity gear set for up to three speeds, which enables seamless shifting with only one friction based clutch. With this platform powertrain units can be realized by using a maximum number of carry over parts (COP) for electric vehicles as well as for powerful hybrids. The derivable hybrid powertrains of the platform system is designed for 48V electric motors which enables the maximum cost potential in combination realized gear set and transmission technology. The real simple powertrain platform concept is furthermore scalable for different vehicle segments optionally with or without a hybrid option.

IAV developed a complete new dual-clutch transmission (DCT) system with focus on flexible usage and costs. As an entry level DCT the design is made for an east-west installation with maximum 200 Nm input torque which could be easily adapted between 100 Nm and 300 Nm. Furthermore the transmission can deliver 6 and 7 speeds with state-of-the-art, robust design solutions and future-oriented reverse gear design with engaged countershafts. The distance between the input shaft and the differential can be changed between 170 mm and 215 mm without changes in the gear set. This is an edge breaking advantage compared to state-of-the-art systems. Beside this flexibility the transmission can realize a first gear ratio from 12.2 to 18.5 and a total ratio spread from 4.4 to 8.5.

Single plate dry clutch is most commonly used in automotive transmission. This paper proposes a unique approach of modelling a single plate dry clutch in Simulink and SimScape simulation environment. The unique approach includes modelling complete clutch into two subsystems as translational and rotational. The translational system is a linear system of diaphragm and cushion spring as a two degree freedom system. Non-linearity of diaphragm and cushion spring has been modeled based on experimental data. The modeled non-linearity helps in simulating dynamic friction torque variation during engagement. In rotational system, friction torque generation between flywheel-clutch disc and pressure plate-clutch disc has been modeled separately. New approach of developing separate friction models help in understanding variation in torque carrying capacity due to rise in temperature of friction pads because of frictional and engine heat.

Abstract This technical paper will provide supporting lubricated test data for the use of thermoplastics like polyamide-imide (PAI) and polyetheretherketone (PEEK) in demanding wear applications at temperatures up to 285°C and pressure velocity exceeding one million psi·ft/min. Applications include needle bearing replacement in transmissions, journal bearings, pumps, marine lower units, continuous variable transmissions, and others. These materials have been used in automotive transmission applications for over 20 years and can be similarly used in small engine applications. By using a thermoplastic, applications benefit through reduced noise and vibration harshness, reduced space, and reduced weight. Mechanical property differences throughout operating temperatures will also be reviewed.

Abstract A simulation tool has been developed that can be used to estimate a fuel economy while driving in a mode test of a motorcycle equipped with a continuously variable transmission (CVT) at an early stage of development. For a precise estimation of a mode fuel economy, it is necessary to accurately estimate the CVT ratio, the engine speed, and the crankshaft torque during driving in a mode. To achieve this, this study has generalized the transmission efficiency of a CVT system. This study has also derived developed balance equations that can take into account the transmission efficiency of CVT and the slippage that occurs when the centrifugal clutch is about to be engaged. In the proposed method, the pulley ratio of CVT, the engine speed, and the torque at the crankshaft were obtained first by solving the developed balance equations at discrete times during driving in a mode.

Abstract The enhancement of efficiency will play a more and more important role in the development of future (small) internal combustion engines. In recent years, the Atkinson (or Extended Expansion) cycle, realized over the crank drive, attracted increasing attention. Several OEMs have investigated this efficiency-increasing principle in the whole range from small engines up to automotive engines until now. In prior publications, the authors outlined the remarkable efficiency potentials of an Extended Expansion (EE) cycle. However, for an internal combustion engine, a smooth running performance as well as low vibrations and noise emissions are relevant aspects. This is especially true for an Extended Expansion engine realized over the crank drive. Therefore, design measures concerning friction and NVH need to be taken to enable possible series production status. Basically, these measures strongly depend on the reduction of the free mass forces and moments.
