Abstract

Truck doors are manufactured in the form of a common upper part that is fixed to either a perforated lower part for trucks with an extra cooler behind the step of the cab or a non-perforated lower part for trucks without an extra cooler.

TRUCK DOOR

 

In trucks, more and more engines require more and more cooling capacity.

To increase the cooling capacity, an extra cooler can be connected in series with the regular cooler of the truck and be located behind the step of the cab.

To lower the wind resistance of the truck, the lower part of the truck door normally covers the step of the cab.

To provide cooling air to the extra cooler, the lower part of the truck door is perforated, e.g. slotted.

However, since every truck is not equipped with an extra cooler, the lower part does not have to be perforated on every truck door.

Thus, the truck doors are manufactured in the form of a common upper part that is fixed to either a perforated lower part for trucks with an extra cooler behind the step of the cab or a non-perforated lower part for trucks without an extra cooler.

Hereby, it will not be necessary to manufacture two different complete doors. Instead, only two different lower door parts will have to be manufactured to be fixed to one and the same type of upper part depending on whether or not the truck is provided with an extra cooler.
