Systems, methods, and devices for an automobile door or window
A trailer truck is the combination of a truck and one or more trailers used to haul freight. A trailer attaches to the truck via a trailer coupling (hitch), with much of its weight borne by the truck. The result is that both the truck and the trailer will have a distinctly different design than a rigid truck and trailer. Exemplary vehicles are provided, such as heavy duty trucks having truck bodies with improved aerodynamic characteristics, including improved drag coefficients.
1. A vehicle, comprising:
a body comprising a nose section, a windshield, and a roof, wherein the nose section comprises an upper portion and a lower portion;
a cabin located within the body, the cabin comprising a seat;
a door comprising a width for providing ingress and egress to and from the cabin; and
a bisecting plane that bisects a width of the vehicle,
wherein the lower portion defines a first slope angle between about 0° and about 6° taken from vertical and that lies in the bisecting plane,
wherein the upper portion defines a second slope angle between about 24° and about 34° taken from vertical and that lies in the bisecting plane,
wherein the windshield defines a third slope angle between about 32° and about 42° taken from vertical and that lies in the bisecting plane,
wherein the roof defines a fourth slope angle between about 71° and about 81° taken from vertical and that lies in the bisecting plane,
wherein a majority of the width of the door is unobstructed by the seat.
2. The vehicle of claim 1 , wherein the vehicle has a drag coefficient that is between about 0.42 and about 0.46.
3. The vehicle of claim 1 , further comprising an electric motor and an electric drive train.
4. The vehicle of claim 1 , wherein the width of the door is completely unobstructed by the seat.
5. The vehicle of claim 1 , wherein the seat is at least two feet from the majority of the width of the door.
6. A vehicle, comprising:
a body comprising a nose section, a windshield, and a roof, wherein the nose section comprises an upper portion and a lower portion;
a cabin located within the body, the cabin comprising a seat and a sleeper;
a door comprising a width located on the body for providing ingress and egress to and from the cabin; and
a bisecting plane that bisects a width of the vehicle,
wherein the lower portion defines a first slope angle between about 0° and 6° taken from vertical and that lies in the bisecting plane,
wherein the upper portion defines a second slope angle between about 20° and about 30° taken from vertical and that lies in the bisecting plane,
wherein the windshield defines a third slope angle between about 31° and about 41° taken from vertical and that lies in the bisecting plane,
wherein the roof defines a fourth slope angle between about 42° and 52° taken from vertical and that lies in the bisecting plane,
wherein a majority of the width of the door is unobstructed by the seat.
7. The vehicle of claim 6 , wherein the vehicle has a drag coefficient that is between about 0.36 and about 0.40.
8. The vehicle of claim 6 , further comprising an electric motor and an electric drive train.
9. The vehicle of claim 6 , wherein the width of the door is completely unobstructed by the seat.
10. The vehicle of claim 6 , wherein the seat is at least two feet from the majority of the width of the door.
