ARRANGEMENT FOR A COMMERCIAL VEHICLE AND A COMMERCIAL VEHICLE

摘要

The invention relates to a commercial vehicle and an arrangement for the vehicle (1) having a multiplicity of wheel shafts (4,5) and a load surface (2) which is supported by a longitudinal chassis element (3). The vehicle incorporates suspension means (8,10) of the air bellows spring type, which make it possible for the load surface to assume a first and a second position. The arrangement comprises a sensor means for detecting a parameter related to the length of the bellows when the load surface is in the second position, and a sensor adapted to detect a parameter which is related to the pressure of the air in the bellows when the load surface is in the second position and a load is arranged on the load surface. A calculation unit is adapted to calculate the weight which will act upon the first wheel shaft on the basis of the parameters of the air bellows spring.
