Apparatus for improving the aerodynamics on a commercial vehicle
The invention exhibits an apparatus for improving the aerodynamics of a commercial vehicle having a cab with doors and below-situated footboards for climbing in and out, and having a front panel in which air inlets are present, wherein the air inlets are connected, via air ducts in or on the panel, to the front wheel case of the commercial vehicle and to an air outlet, wherein the at least one footboard of the cab can be folded away and has at least one through-flow region in the vehicle longitudinal direction.
1. An apparatus for improving the aerodynamics of a commercial vehicle having a cab with doors and at least one footboard for assisting an operator in climbing in and out of the cab, and having a front panel defining at least one air inlet, wherein the at least one air inlet is fluidly connected to at least one air outlet at a front wheel case, wherein the at least one footboard of the cab can be folded into a folded-away state, and wherein the at least one footboard has at least one through-flow region in a longitudinal direction of the vehicle which fluidly connects the at least one air inlet to the at least one air outlet.
2. The apparatus according to claim 1 , wherein the at least one footboard, in the folded-away state, fits into a set-back region of the front panel.
3. Apparatus according to claim 1 , wherein the at least one through-flow region extends in the longitudinal direction.
4. Apparatus according to claim 1 , wherein the at least one air inlet is defined by the front panel of the commercial vehicle along a plane defined at a front of the vehicle.
5. An apparatus according to claim 1 , wherein an outer contour of the at least one footboard constitutes a continuation of an outer contour of the vehicle or front panel.
6. An apparatus for improving the aerodynamics of a commercial vehicle having a cab with doors and at least one footboard for assisting an operator in climbing in and out of the cab, and having a front panel defining at least one air inlet, wherein the at least one air inlet is fluidly connected to at least one air outlet at a front wheel case, wherein the at least one footboard of the cab can be folded into a folded-away state, and wherein the at least one footboard has at least one through-flow region in a longitudinal direction of the vehicle, and wherein an outer contour of the at least one footboard constitutes in a continuation of an outer contour of the vehicle or front panel.
7. The apparatus according to claim 6 , wherein the at least one footboard, in the folded-away state, fits into a set-back region of the front panel.
8. The apparatus according to claim 6 , wherein the flow-through region fluidly connects the at least one air inlet to the at least one air outlet.
9. Apparatus according to claim 6 , wherein the at least one air inlet is defined by the front panel of the commercial vehicle along a plane defined at a front of the vehicle.
10. A commercial vehicle, comprising:
a cab with doors and at least one footboard for assisting an operator in climbing in and out of the cab;
a front panel defining at least one air inlet;
a front wheel case defining at least one air outlet;
at least one air duct fluidly connecting the at least one air inlet to the at least one air outlet;
the at least one footboard being foldable into a folded-away state; and
the at least one footboard defining a through-flow region in a longitudinal direction of the vehicle fluidly connecting the at least one air inlet to the at least one air outlet while in the folded-away state.
11. A commercial vehicle according to claim 10 , wherein an outer contour of the at least one footboard constitutes a continuation of an outer contour of the front panel while the at least one footboard is in the folded-away state.
12. The commercial vehicle according to claim 10 , wherein the at least one footboard fits into a set-back region of the front panel while in the folded-away state.
13. The commercial vehicle according to claim 10 , wherein the at least one air inlet is defined by the front panel of the commercial vehicle along a plane defined at a front of the vehicle.
