Trailers with front steering axle
Center-axle trailers
We calculate the D factor
this is a theoretical tractive force indicator defining the hypothetical dynamic horizontal force between the towing vehicle and the trailer with a front steering axle (without vertical pressure on the hitch!)
We calculate the Dc coefficients
Dc - This is a theoretical tractive force indicator defining the hypothetical dynamic horizontal force between the towing vehicle and the center-axle trailer.
D = g ×
T × R
T + R
=
kN
We calculatedopuszczalna masa całkowita pojazdu w tonach
permissible gross trailer weight in tons
sum of the maximum axle load transferred to the ground by the trailer in tonnes
g = acceleration of gravity: 9.81 m/s²
T = permissible gross vehicle weight in tonnes
R = permissible gross trailer weight in tonnes
