Vibratie accelerare


Recommended Posts

Salut

Revin si eu cu o problema. intre 1800-2500 rot/min la accelerare brusca in treptele a2a si a3a apare o vibratie a masinii. Intensitatea e direct proportionala cu acceleratia, daca accelerez usor, nu se simte absolut nimic.

Problema a aparut dupa un incident dupa care a necesitat sa fie schimbat cadrul puntii si portfuzeta. Inainte sa duc masina pentru reparatie, nu exista absolut nicio problema. Din momentul cand au dat cardanul jos si a fost pus inapoi, au aparut vibratiile. Mi s-a spus ca au facut semn si au pus cardanul inapoi la semn. Alte probleme legat ee volanta sau altele nu vad cu ar putea sa apara pentru ca masina a stat in perioada asta iar inainte nu exista niciun fel de vibratie.

 

Multumesc

De ce ar avea cardanul o pozitie anume de montare?

Nu ar trebui sa fie echilibrate ambele bucati, si indiferent de cum le-ai pune, ar trebui sa fie ok?

Intreb pentru ca si eu am desfacut cardanul, si nu am facut nici un semn, si nu am simtit nimic diferit...

Astazi am rezolvat problema. Suport cardan (Ștender, sper ca nu gresesc denumirea) era montat invers. A desfacut doua suruburi, a intors piesa si a disparut vibratia.

Va multumesc frumos.
