    Re: Tipuri cutii automate pe Jeep

    Stii, cumva, rapoartele de multiplicare ale convertoarelor de cuplu? La Jeep , sau la altele.
    Ma intereseaza pt. o comparatie cu masinile cu reductor.
    Sa cunosti, sa vrei - vei putea face !

        Re: Tipuri cutii automate pe Jeep

        Convertorul de cuplu de la transmisiile automate este, in fapt, echivalentul ambreiaj+reductor mecanic de pe masinile cu cutie de viteze manuala. Spre deosebire de reductor, convertorul de cuplu este actionat hidraulic, continuu si automat, in ultima instanta, de pedala de acceleratie.
        In exemplul din linkul tau, convertorul multiplica cuplu de 2,14 ori. Stiu ca pentru automobile, in functie de destinatie, acest raport variaza intre 1,8 si 3, sau chiar mai mult.

        Intrebarea mea, sugerata de postul tau si o discutie de pe forum era: stii (sau poti indica o sursa) care este acest raport pt. Jeep, sau alte masini cu veleitati de teren pt. a face o comparatie cu cutiile manuale, cu reductor?

          Eu unul n-am gasit informatii legate de raportul de multiplicare. Mai degraba gasesti informatii legate de stall speed. Si chiar si stall speed e influentat de greutatea masinii si motor
          Oricum raportul de multiplicare scade pe masura ce se invarte axul de intrare a cutiei.

            Ai dreptate; in faza de stall speed se manifesta, de obicei, efectul maxim de multiplicare a cuplului, care depinde de sursa de putere (motor) si sarcina (greutate, teren etc.). E normal sa scada pe masura ce motorul/forta de tractiune incepe sa depaseasca sarcina/rezistenta la inaintare.

            Daca ai asemenea date, sunt interesat.

              Raspunsul meu :
              nu stiu ,nu ma intereseaza si nici nu ma va interesa niciodata (teoria) in schimb practica spune ca azi am reusit sa fac sa functioneze combinatia :motor Vw 1,9 tdi ARL 150 cp resoftat + cutie automata AW4 +punti portale Volvo C303 + roti 37" pe o tubulara de extrem




              P.s. In teorie il las pe @ssrli sa se descurce

                Doar din ce am gasit cotrobaind pe net:

                AW4 dupa 4.0: 2100 rpm
                42re si 46rh dupa V8-uri in ZJ: 1800 rpm.

                  Multumesc @ssrli.
                  Probabil e vorba de turatiile de cuplu maxim (2100,1800). Ma interesa raportul de multiplicare a cuplului (functia de "reductor").
