Modular cab, sleeper and roof structural assembly for a truck-tractor vehicle
A modular cab/sleeper/roof structural assembly for a truck-tractor vehicle according to the present invention provides greater manufacturing flexibility and unrestricted access between a cab/sleeper unit. The structural assembly includes a top-free cab unit having a front wall, opposing side walls, and a bottom portion. A top-free sleeper unit positioned behind the cab unit has a rear wall, opposing side walls, and a bottom portion. Fasteners couple the cab unit and the sleeper unit such that an upwardly opened carriage assembly is formed. A unitary roof member fixedly encloses the opened carriage assembly and forms an integral modular unit. The unitary roof member has a front portion connected to the front wall of the cab unit, a rear portion connected to the rear wall of the sleeper unit, and opposing side portions connected to the opposing side walls of the cab and sleeper units. The cab unit, sleeper unit and roof member are not independent structures; however, when they are assembled, the units constitute a durable cab/sleeper unit.
1. A modular cab/sleeper/roof structural assembly for a truck-tractor vehicle, comprising:
a roof-free cab unit having a front wall, opposing side walls, and a bottom portion;
a roof-free sleeper unit positioned behind said cab unit, and having a rear wall, opposing side walls, and a bottom portion;
fasteners for fixedly joining said cab unit and said sleeper unit such that an upwardly opened carriage assembly is formed; and
a unitary roof member fixedly enclosing said opened carriage assembly thereby forming an integral modular unit, said unitary roof member having a front portion connected to said front wall of said cab unit, a rear portion connected to said rear wall of said sleeper unit, and opposing side portions connected to said opposing side walls of said cab unit and said sleeper unit.
2. The assembly of claim 1 , wherein said fasteners are spaced substantially evenly between contact surfaces of said cab unit and said sleeper unit.
3. The assembly of claim 2 , wherein said fasteners are removable bolts.
4. The assembly of claim 2 , wherein said fasteners are clamping bolts.
5. The assembly of claim 1 , further comprising second fasteners for fixedly joining said carriage assembly and said roof member.
6. The assembly of claim 5 , wherein said second fasteners are spaced substantially evenly between contact surfaces of said carriage assembly and said roof member.
7. The assembly of claim 6 , wherein said second fasteners are removable bolts.
8. The assembly of claim 6 , wherein said second fasteners are clamping bolts.
9. The assembly of claim 1 , wherein said integral modular unit is mounted to a chassis frame member by mounting fasteners.
10. The assembly of claim 1 , wherein said cab unit is adapted to match a plurality of different sizes of said sleeper unit.
11. The assembly of claim 1 , wherein said cab unit is adapted to match a plurality of different sleeper and roof combinations.
12. The assembly of claim 2 , wherein said fasteners are a combination of bolts and structural adhesives.
13. The assembly of claim 6 , wherein said second fasteners are structural adhesives.
14. The assembly of claim 6 , wherein said second fasteners are a combination of bolts and structural adhesives.
15. The assembly of claim 13 , wherein said structural adhesives are evenly applied between contact surfaces of said carriage assembly and said roof member.
