Abstract

An improved cab for a cab-over-engine configured tractor has a driver'"'"'s seat mounted to a floor of the cab wherein the floor is substantially flat. The tractor includes a frame for supporting the cab. An engine is mounted to the frame substantially beneath the cab, yet rearward of the floor so that the floor may be substantially flat. Auxiliary devices such as the radiator, radiator fan, and alternator are mounted to the frame remote from the engine and powered by a drive train that extends from the auxiliary devices to the engine.

Claims

1. A tractor for a truck wherein the tractor is constructed for operation by a driver and wherein the tractor is constructed for hauling a trailer, said tractor comprising:

a cab compartment for the driver of the truck, said cab compartment including a driver seat and a passenger seat mounted to a floor of said cab compartment, said floor being substantially flat to provide a substantially unobstructed pathway between said driver seat and said passenger seat, said driver seat being positioned so that when the driver is seated therein the driver faces toward a forward portion of said cab compartment and away from a rearward portion of said cab compartment, said cab compartment including a sleeper bunk mounted to said rearward portion thereof, a bulkhead positioned intermediate said forward and rearward portions of said cab compartment, and a throughway to permit the driver to enter said rearward portion from said forward portion, said cab compartment further including a roof on the top thereof constructed for providing sufficient height interior of said cab compartment to enable the driver to stand upright on said floor;

frame means for supporting said cab compartment, said frame means having a front end and a rear end, said cab compartment being supported proximate said front end of said frame means, said frame means including means for releasably coupling the trailer thereto;

engine means for providing a drive force to the tractor, said engine means being mounted to said frame means and positioned substantially beneath said cab compartment rearward of said floor so that said floor may be positioned lower than the top of said engine means and may be substantially flat;

radiator means for transferring heat from a liquid coolant to air outside said radiator means, said radiator means being mounted to said front end of said frame means, said radiator means including means for conducting said liquid coolant to said engine means for cooling said engine means;

a fan mounted to said front end of said frame means, said fan being mounted proximate said radiator means to create air flow through said radiator means thereby to improve the transfer of heat from said radiator means to air outside said radiator means;

drive shaft means for providing rotational drive movement to said fan, said drive shaft means being positioned substantially beneath said floor and extending from said front end of said frame means to said engine means, said drive shaft means being coupled to said engine means to be rotated by said engine means;

alternator means for generating electrical energy, said alternator means being mounted to said front end of said frame means remote from said engine means, said alternator means being coupled to said drive shaft means for converting rotational energy provided by said drive shaft means to electrical energy; and

an aerodynamic fairing mounted to said roof of said cab compartment.

2. A tractor for a truck wherein the tractor is constructed for operation by a driver and wherein the tractor is constructed for hauling a trailer, said tractor comprising:

a cab compartment for the driver of the truck, said cab compartment including a driver seat and a passenger seat mounted to a floor of said cab compartment, said floor being substantially flat to provide a substantially unobstructed pathway between said driver seat and said passenger seat, said driver seat being positioned so that when the driver is seated therein the driver faces toward a forward portion of said cab compartment and away from a rearward portion of said cab compartment, said cab compartment including a sleeper bunk mounted to said rearward portion thereof;

frame means for supporting said cab compartment, said frame means having a front end, a rear end, and a longitudinal axis extending from said front end to said rear end said cab compartment being supported proximate said front end of said frame means, said frame means including means for releasably coupling the trailer thereto; and

engine means for providing a drive force to the tractor, said engine means having a longitudinal axis and being mounted to said frame means so that its longitudinal axis is substantially parallel to the longitudinal axis of said frame means and so that said engine means is positioned substantially beneath said cab compartment rearward of said floor.

3. The tractor as recited in claim 2 wherein said cab compartment further comprises a bulkhead positioned intermediate said forward and rearward portions of said cab compartment and including a throughway to permit the driver to enter said rearward portion from said forward portion.

4. The tractor as recited in claim 2 wherein said cab compartment further comprises a roof on the top thereof constructed for providing sufficient height interior of said cab compartment to enable the driver to stand upright on said floor.

5. The tractor as recited in claim 4 further comprising aerodynamic fairing means mounted to said roof of said cab compartment for providing aerodynamic efficiency to said tractor.

6. The tractor as recited in claim 2 further comprising:

radiator means mounted to said front end of said frame means remote from said engine means for transferring heat from a liquid coolant to air outside said radiator means;

a fan mounted to said front end of said frame means proximate said radiator means for creating air flow through said radiator means to improve the transfer of heat said liquid coolant to the air outside said radiator means; and

drive shaft means for providing rotational energy to said fan means, said drive shaft means extending from said front end of said frame means to said engine means for transferring rotational energy from said engine means to said fan.

7. The tractor as recited in claim 2 further comprising:

alternator means for generating electrical energy, said alternator means being mounted to said front end of said frame means remote from said engine means; and

drive shaft means for providing rotational energy to said alternator means, said drive shaft means extending from said front end of said frame means to said engine means for transferring rotational energy from said engine means to said alternator means.

8. The tractor as recited in claim 6 further comprising alternator means for generating electrical energy, said alternator means being mounted to said front end of said frame means remote from said engine means, said alternator means being coupled to said drive shaft means for converting rotational energy provided by said drive shaft means to electrical energy.

9. A tractor for a truck wherein the tractor is constructed for operation by a driver to haul a trailer, said tractor comprising:

cab means for providing a riding compartment for the driver of the tractor, said cab means including seat means mounted to a floor of said cab means for seating the driver of the tractor, said cab means having a forward portion and a rearward portion, said cab means including a sleeping bunk mounted to said rearward portion;

frame means for supporting said cab means, said frame means having a front end and a rear end, said cab means being supported proximate said front end of said frame means, said frame means including coupling means for releasably coupling the trailer to said frame means; and

engine means for providing a drive force to said frame means, said engine means having a longitudinal axis and being mounted to said frame means rearward of said floor of said cab compartment so that said longitudinal axis extends parallel an axis defined from said front end of said frame means to said rear end thereof and so that said floor is substantially flat.

10. The tractor as recited in claim 9 further comprising:

radiator means mounted to said front end of said frame means remote from said engine means for transferring heat from a liquid coolant to air outside said radiator means;

a fan mounted to said front end of said frame means proximate said radiator means for creating air flow through said radiator means to improve the transfer of heat from said liquid coolant to the air outside said radiator means; and

drive shaft means for providing rotational energy to said fan, said drive shaft means extending from said front end of said frame means to said engine means for transferring rotational energy from said engine means to said fan.
