In addition to fuel consumption and efficiency the expectations in driving comfort of heavy duty vehicles were substantially increased in the last years. The driveline has an essential role in drivability performance of the vehicle. Since it determines the driving efficiency as well, simple, but robust devices were quite widespread in production, but these can usually make driving more difficul...

This work deals with the longitudinal comfort issue of a plug-in hybrid vehicle and in particular with the control of driveline oscillations caused by gear shifts. The rear drive torque generated by a motor is used to compensate the effect of clutch opening and closing. Takagi-Sugeno (TS) method is used to approximate the nonlinear longitudinal dynamics model. Simulations using a detailed vehic...

In automotive dry clutch systems the cushion spring plays an important role in terms of gradually torque transmitted during the engagement phase. In fact, it strongly influences the clutch torque transmission from engine to driveline through its non-linear loaddeflection curve. Therefore, to improve the gearshift performance in automated manual transmission is fundamental the knowledge of the c...

We report interruption of left ventricular assist device (VAD) support by way of outflow graft ligation and driveline excision while leaving the pump in situ. In this case, the indication for mechanical assist device separation was myocardial recovery, which occurred following 9 months of support. This case report demonstrates the feasibility of separating a patient from a VAD without the need ...

A tractor transmission is usually very complex with a lot of gear pairs, shafts and bearings in it. Modern transmissions have also several functionalities like shifting without clutch, 4WD/2WD forward/reverse shuttle PTOs. They must work smoothly quietly an automotive transmission, but working condi-tions are much more severe. be reliable different kind conditions fields applications. Due to th...
