Abstract:Dry clutch semi linkage manipulation is often resorted to on congested roads, but frequent semi linkage may generate a lot of heat and cause the clutch failure. An analysis was made of the heat load of the clutch during semi linkage process. A dry clutch engagement model, an engine model and a resistance model were established respectively. A control strategy was proposed, which overcame the running resistance by controlling the degree of engagement of the clutch with a single semi linkage manipulation so as to avoid the frequent semi linkage operations. A comparative study was made of the slipping friction power before and after semi linkage control on the pavement of 2% and 5% slope as well as the pavement in good condition. Results show that the slipping friction power was reduced by 3.72 %, 36.00% and 71.35% respectively.
