toeren en kmh verhouding?

Berichtdoor Marijn94 » 13 apr 2017, 23:01

Beste lede,

ik heb een vraag, ik rij in een W126 300SE van '87 en hij is wat hoog toerig naar mijn idee.
Zodra ik 80 km/h rij maakt hij 2500 toeren, zover ik weet schakelt hij wel in alle versnellingen.
Als ik hem in zijn 3 heb staan en schakel naar zijn D dan gaat hij nog een keer over.
De verhouding van het differentieel is 3.46

Naar mijn idee moet hij rustiger kunnen lopen, met mijn 500 is het een groot verschil

Weet iemand of dit zo hoort of kan er iets mis zijn?

alvast bedankt

Mvg,
Marijn

Je kunt het uitrekenen:
snelheid = toerental x 60 x bandomtrek / overbrenging differentieel / overbrenging versnellingsbak
(toerental in omwentelingen per minuut, 60 minuten in een uur)

De omtrek van een band kun je als volgt uitrekenen:
bandomtrek = pi x (velgdiameter + 2 x verhouding hoogte-breedte x breedte band)
Bij een 205/65R15 band (het normale formaat voor een 300SE):
velgdiameter = 15 inch = 381 mm (een inch is 25,4 mm)
verhouding hoogte-breedte = 65% = 0,65
breedte band = 205 mm
dus bandomtrek = pi x (381 + 2 x 0.65 x 205) = 2034 mm = 0,002034 kilometer

overbrenging versnellingsbak in de 4e versnelling is 1
dus snelheid = 0,002034 x 60 x 2500 / 3,46 / 1 = 88 km/u
overbrenging versnellingsbak in de 3e versnelling is 1,44
dus snelheid = 0,002034 x 60 x 2500 / 3,46 / 1,44 = 61 km/u

Bij de 500 is de overbrenging van het differentieel 2,24, overbrenging versnellingsbak in de 4e is ook hier 1
dus snelheid = 0,002034 x 60 x 2500 / 2,24 / 1 = 136 km/u

Het klopt dus wel zo ongeveer (vergeet niet dat toerenteller en snelheidsmeter geen precisie-instrumenten zijn en dat de bandomtrek een theoretische berekening is die in de praktijk kan afwijken).
Optimum aut nihil.
