On the Mechanical Friction Losses Occurring in Automotive Differential Gearboxes
Figure 10
(a) Yield of a differential gearbox as a function of the load parameter for various sets of coefficients of friction : (0.03, 0.05) in a dashed line, (0.05, 0.07) in a dash-dot line, (0.03, 0.07) in a dotted line and in a solid line for , and undergoing a concomitant linear increase from to and to , respectively, with ; the thick solid line gives the yield of the differential gearbox without any losses (which is constant) with the load parameter ; that is, , . (b) Loss ratio of the -mechanism (with ) as a function of the load parameter and with the same sets of coefficients of friction as in (a): without (black solid line) or with (black dashed line) a linear decrease in from to , (red line), (blue line), and (green line).
