Description

40 520 704 att via hydraulledningama 7 stänga tillförseln av hydrauliskt matartryck till vältens hydrauliska valsbromsar 8, vilka är anordnade till att ge full bromseffekt vid bortfall av matartrycket. Den ökade bromseffekt som de aktiverade valsbromsama tillför, reducerar dieselmotorvarvtalet till dess ett andra i ECM:en inprogramrnerat varvtal understigs, t ex 2500 varv/minut.
ECM:en är programmerad till att bryta jordanslutningen när detta lägre varvtal underskrids och påverkar då i omvänd ordning den sekundära bromsanordningen till att frilägga valsbromsarna. Skulle motorvarvtalet åter öka och överskrida det maximala, upprepar den kontinuerligt övervakande sekundära bromsanordningen proceduren.
Uppfinningen kan även tillämpas vid andra typer av bromsarrangemang där tex hydraulventilens 5 manöverrelä 4 skall strömanslutas för att det hydrauliska matartrycket till valsbromsarna skall upphöra.
