Extra heavy vehicles, depending on their application and configuration, demand higher torque, longer drive-off time, many gear shifts, more complex and unusual maneuvers. These situations lead to a high thermal energy applied on the clutch, increasing clutch wear and, in extreme conditions, leading to a thermal destruction. These events demand a technically and economically viable solution as well as a compact layout for easy implementation to increase the clutch performance and life. Since the problem is of thermal nature, without the possibility of forced cooling or the use of a larger clutch assembly to faster dissipate the energy, the proposed improvement has been focused on faster energy absorption in order to minimize peak temperature, both in occurrences and in magnitude.
