Design and traction performance of the movable lug wheel
Journal of Terramechanics, 1998A movable lug wheel using a rollers-sliding groove mechanism was designed, constructed and tested. Two types of lug moving patterns of the movable lug wheel were proposed and evaluated. Tests were conducted in a soil bin test apparatus to determine the traction performance of the wheel as affected by lug moving pattern, lug spacing, horizontal load and

The Influence of Fluid Rheology on the Performance of Traction Drives
Journal of Lubrication Technology, 1979The performance of traction drives depends to a large extent on the rheological properties of the fluid in the EHL contact. Through the use of the recently proposed J + T constitutive equation, the influence of elastic effects in the fluids is examined. The results were compared with those obtained from conventional analysis.

Quantifying the Rheological Basis of Traction Fluid Performance
SAE Technical Paper Series, 1999<div class="htmlview paragraph">This paper proposes a new approach to quantifying the rheological effects that come into play in traction fluids under different regimes of operation in elastohydrodynamic (EHD) contacts. We take account of shear thinning and viscoelasticity and of the joint temperature and pressure dependence of these effects and ...

Performances of Insulation Systems for Inverter-fed Traction Motors
2002The steep fronted pulses at high switching frequencies occurring in adjustable speed drives (ASD) of new generation may produce premature failures of the winding insulation of induction motors, as those adopted for traction applications. Life curves of such systems are typically not available for waveforms generated by the modern inverters ...
