Probleme Ambreiaj

[Danyell]

Ideea era alta. C-am ce durata de viata are piesa in conditii de utilizare normala. Stiu ca suna ciudat, eram in dubii daca exista ceva prevederi. Multumesc

[IancuMIC]

Kit-ul ambreiaj, ca si o planetara, un pivot, il schimbi cand se defecteaza; nu e prevazut un termen sau numar de kilometrii; ar fi culmea.

[Danyell]

Exista vreo mentiune la cat timp se schimba ambreiajul la logan? Stie careva? Sau se schimba cand da semne ca ar crapa?

[alessandro]

Zgomot din arcuri, placa de presiune sparta, rulment de presiune stricat...etc

Ciudat...Valeo nu pune ca ar fi nici una din aceste cauze.

Am reglat azi ambreiajul unui Logan 1.6 care avea acest zgomot la ralanti...dupa acest reglaj zgomotul a disparut.
Ii statea pedala foarte sus iar eu am pozitionat-o jos.

Daca luam in considerare doar acest fapt ne dam seama ca zgomotul nu vine din arcuri sau placa sparta.

Chit ca nu are lagatura cu autoturismele iata ce spune Valeo despre cunoscutul zgomot :

Causal Factors:
The three primary causes of this condition are as follows:
1. Release Linkage - The mechanical rod clutch release linkage used in
most North American trucks can become loose at the various joints and
pivot locations and can rattle or buzz in reaction to engine operation
when no load is placed on the linkage. Many truck manufacturers have a
service kit available which includes rubber washers which are added to
the joints and pivots to eliminate the looseness and noise.

2. Release Yoke - When the release yoke is not mounted correctly in
the center of the clutch housing, or if the side halfshafts are installed too
deeply into the yoke, the clutch release bearing can be pulled off center
or a binding condition can exist. This creates a side loading condition
and it can result in a tapping noise between the housing side flats and the
inside edges of the release yoke or the ends of the shafts. This can be
corrected by loosening the yoke “pinch bolts” and repositioning the yoke
half shafts and/or by relocating the external lever or collar on the half
shafts to allow the yoke to move to a central location without side load or
binding.
Release Bearing Noise with Pedal Up
(Continued …)

3. Clutch Release Bearing - On certain older high mileage installations,
the attachment between the release bearing assembly and the clutch
pressure plate diaphragm fingers can loosen creating a noise. This
looseness is most often caused by clutch misadjustment, contaminants in
the bearing grease, use of an overly stiff bearing grease or unusual
torsional vibrations in the powertrain. The looseness can often be
corrected by installing an additional load washer in the attachment joint,
or in severe cases, the clutch unit may need replacement.

P.S. zilele urmatoare voi trimite un mail la Valeo in care voi solicita un raspuns cu privire la problema zgomotului la ralanti

Am avut eu rupte doua raze dar am luat o Dacie papuc pe bot la 120 si probabil parghia de actionare a ambreiajului a lovit in soare ca era blocat ambreiajul dupa accident.

[alessandro]

Pana acum nu a explicat nimeni clar de unde vine tacanitul la ralanti.

X loveste in Y si se produce un zgomot

Cine este X ? cine este Y ?

Nu varful unei raze cum spui tu, da' nu conteaza; fisura apare de la baza acelei raze catre interior.

Cam asa se fisureaza diafragma la placa de presiune; "raze", efectiv rupte, nu prea se intampla.

[tzeegunoo]

Placa era crapata la baza , intre 2 raze, si soarele era deformat/valurit. Fotografia nu e de la ambreiajul meu , dar crapatura e identica. Am pus exedy, sper sa fie in regula in viitor.
PS. Cu kitul exedy , zgomotul de arcuri nu dispare complet.

[Ronin]

Unu sau mai multi catei rupti la placa, am patit si eu asta si stiu ce spun

[maurice2001]

Am uitat sa spun ca am motor de 1,4.
Tzacanitul acela fin dispare cand calc pedala de ambreiaj.Deci sa inteleg ca nu e de la rulmentul de presiune ci de la placa zgomotul.
