Definitions
- the invention relates to a roof attachment for a cab of a commercial vehicle, which has a left A pillar in the forward driving direction and a right pillar in the forward driving direction and at least one rear left and at least one rear right pillar arranged behind a door cutout in the forward driving direction, the roof attachment having at least two roof bows has that are covered by a roof skin.
- a supporting structure for a driver's cab of a commercial vehicle is known from US Pat. No. 6,315,351.
- the structure has a total of three roof bows, two of which are oriented in the direction of travel and a third is oriented transversely to the direction of travel.
- the roof bows serve to stabilize the structure of the driver's cab.
- the object of the invention is to provide a roof attachment for a driver's cab, which has a high degree of stability and is able to stabilize the driver's cab even in the event of a vehicle impact.
- a roof attachment for a cab of a commercial vehicle which has a left A pillar in the forward direction and a right pillar in the forward direction as well as at least one rear left and at least one rear right in the forward direction has a door cutout arranged pillar, wherein the roof attachment has at least two roof bows which are covered by a roof skin, in which a first roof bow from the left A pillar to the rear right pillar and a second roof bow from the right A pillar to the rear left column runs.
- the A-pillars are the front pillars of the cab of the commercial vehicle in the forward direction. They are arranged in the forward direction of travel in front of a door cutout of a driver's door.
- the rear pillars can be both pillars that are arranged on the side walls of the driver's cab and pillars that are arranged on a rear wall of the driver's cab.
- the roof bars are arranged so that they start from the A-pillars and run diagonally to the rear. Since the roof bows run from the A pillar on one side to a rear pillar on the other side, they cross each other.
- Such a topological structure of the roof bow in which the roof bow is not oriented exclusively in the direction of travel or transverse to the direction of travel, leads to a particularly high stability of the structure of the driver's cab.
- a high degree of safety for the occupants of the driver's cab is achieved, in particular if an impact occurs with an associated force from obliquely the front.
- the structure according to the invention enables a good flow of force in such an impact.
- a right B pillar is provided as the rear right pillar and a left B pillar is provided as the rear left pillar.
- the B-pillar is the pillar that is arranged behind the door opening in the forward direction of travel of the vehicle. Roof bows that run from the A-pillars on one side to the B-pillars on the other side ensure an improved flow of power between the A-pillars and the B-pillars.
- a column arranged in the forward direction of travel to the left of the roof center and on the rear wall of the driver's cab is provided as the rear left column and a column arranged in the forward direction of travel to the right of the roof center and on the rear wall of the driver's cab is provided.
- this improves the flow of force from a front part of the driver's cab to a rear part of the driver's cab.
- the first roof bow extends from the left A pillar to a right B pillar and the second roof bow extends from the right A pillar to a left B pillar and a third roof bow from the left A pillar to a forward direction to the right of the center of the roof on the rear wall of the driver's cab and a fourth roof bow from the right A-pillar to a pillar to the left of the roof center on the rear wall of the driver's cab.
- Such a structure accordingly has at least four roof bows, two of which originate from the same A pillar. Of these two roof bars an A- Pillar runs one to the B-pillar on the opposite side of the vehicle and the other to a pillar which is arranged on the opposite side of the vehicle on the rear wall.
- This structure ensures a very good flow of power both between the two sides of the cab and between the front and rear area. A high degree of stability is achieved and thus the safety for the occupants of the cab is guaranteed.
- the two roof bows starting from an A pillar are brought together in a connection area to the A pillar.
- the A-pillar only has one roof bow, which then branches into the two roof bow at a node.
- Such an embodiment allows a one-piece design of the connection area of two roof bows.
- the four roof bows enclose a kite-shaped surface, one diagonal of which extends in the direction of travel and the other diagonal of which extends transversely to the direction of travel.
- a kite-shaped surface is a quadrangular surface that is axisymmetric with respect to one of its diagonals.
- the kite-shaped surface formed by the roof bows is axisymmetric with respect to the diagonal pointing in the direction of travel.
- the kite-shaped area In the forward direction of travel, the kite-shaped area is delimited by the roof bars that run from the A-pillars to the B-pillars on the opposite side of the cab.
- the kite-shaped area is delimited by the roof bars, that of the A-pillars to the Columns run along the rear wall of the cab.
- the roof attachment has a kite-shaped roof hatch, which is arranged in the kite-shaped surface.
- the roof attachment has a rectangular roof hatch which is aligned approximately parallel to one of the roof bows.
- a horizontally arranged peripheral frame is provided, with which the roof bow is connected.
- the frame leads to a further increase in the stability of the roof attachment.
- it allows the roof attachment to be installed separately before it is connected to the cab.
- it can represent the boundaries of the roof covering, which extends over the roof bows.
- the roof attachment is designed as a high roof, which has four side parts and a horizontally oriented central part, and the four roof bows each have three sections, of which the first and the third section each parallel to one of the side parts of the high roof and the second Section run parallel to the central part of the high roof.
- the side parts are preferably arranged such that they form a plane with a side area or with a front area or a rear area of the driver's cab.
- the first part of each roof bow runs from one of the A-pillars either parallel to the left or right side part or parallel to the side part lying in the forward direction of travel up to the height of the horizontally oriented middle part.
- the second part of the roof bow runs over the horizontally aligned middle part.
- the third part of the roof bow which runs either parallel to the left or right side part or parallel to the rear side part in the forward direction of travel to a rear pillar.
- the design of the roof attachment as a high roof is particularly expedient from an aerodynamic point of view. Due to the high roof, the air resistance can be reduced by the transition between the driver's cab and the superstructure of the commercial vehicle.
- two roof bows which run from the A-pillars on one side to the B-pillars on the other side, intersect in the area of the transition between the horizontally oriented central part of the high roof and the side part lying forward in the forward direction of the high roof.
- two roof bows intersect, which run from the A-pillars on one side to pillars that are arranged on the other side on the rear wall of the driver's cab in the forward direction of travel, in the region of the horizontally oriented central part of the high roof.
- the underlying task can also be solved by a driver's cab for a commercial vehicle with a roof attachment according to the invention.
- the roof attachment can either be detachable or permanently connected to the cab.
