Floor assembly for a driver's cab and method of making
View Patent ↗A floor assembly for a driver's cab of a commercial vehicle, has a tunnel section extending in the direction of travel of the vehicle and floor sections which extend, with regard to the direction of travel, next to the tunnel section and are fastened laterally to the tunnel section. In order to simplify the formation of variants with the floor assembly, the tunnel section is of multipart construction and has, with regard to the direction of travel, a front tunnel part and a rear tunnel part connected thereto. The rear tunnel part begins at the rear floor assembly end and ends at the front tunnel part which, for its part, ends at the front floor assembly end. The tunnel parts are fastened in each case directly or indirectly to the floor sections.

6. The floor assembly according to claim 2 , wherein the rear tunnel part extends above an internal combustion engine which, in an installed state of the floor assembly, is arranged below the cab.
7. The floor assembly according to claim 1 , wherein the rear tunnel part is designed as a removable tunnel cover giving access to an internal combustion engine which, in an installed state of the floor assembly, is arranged below the cab.
8. The floor assembly according to claim 2 , wherein the rear tunnel part is designed as a removable tunnel cover giving access to an internal combustion engine which, in an installed state of the floor assembly, is arranged below the cab.
9. The floor assembly according to claim 5 , wherein the rear tunnel part is designed as a removable tunnel cover giving access to the internal combustion engine which, in an installed state of the floor assembly, is arranged below the cab.
10. The floor assembly according to claim 1 , wherein connecting zones, with which the rear tunnel part is fastened to the front tunnel part and to rear attachment parts or to the floor sections, extend approximately in a connecting plane which extends approximately horizontally.
11. The floor assembly according to claim 3 , wherein connecting zones, with which the rear tunnel part is fastened to the front tunnel part and to rear attachment parts or to the floor sections, extend approximately in a connecting plane which extends approximately horizontally.
12. The floor assembly according to claim 5 , wherein connecting zones, with which the rear tunnel part is fastened to the front tunnel part and to rear attachment parts or to the floor sections, extend approximately in a connecting plane which extends approximately horizontally.
13. The floor assembly according to claim 1 , wherein the front tunnel part extends approximately along the flooring regions.
14. The floor assembly according claim 10 , wherein the front tunnel part extends approximately along the flooring regions.
15. A floor assembly for a cab of a commercial vehicle, comprising:
a tunnel section extending in a direction of travel of the vehicle,
a left floor section which extends on the left, with regard to the direction of travel, next to the tunnel section and is fastened laterally to the tunnel section, and
a right floor section which extends on the right, with regard to the direction of travel, next to the tunnel section and is fastened laterally to the tunnel section,
wherein the tunnel section and the floor sections extend in the direction of travel from a common, rear floor assembly end as far as a common, front floor assembly end,
wherein the tunnel section is of multipart construction and, the regard to the direction of travel, has a front tunnel part and a rear tunnel part connected thereto,
wherein the rear tunnel part begins at the common rear floor assembly end and ends at the front tunnel part which ends at the front floor assembly end,
wherein the front tunnel part and the rear tunnel part are fastened in each case directly or indirectly to the floor sections,
wherein the front tunnel part has, at a front end with regard to the direction of travel, an indentation which protrudes into the cab and, in an installed state of the floor assembly, covers a main heat exchanger of a cooling circuit of an internal combustion engine of the vehicle from above, and
wherein a region of the front tunnel part, which said region adjoins the indentation to a rear, lies lower than an upper side of the indentation.
