Abstract

In the case of a travel trailer having a battery and an axle ( 13 ) or a tandem axle, the battery ( 9 ) is designed for supplying electricity to a travel drive of a towing vehicle and/or to an optional travel drive of the travel trailer during trailer travel in road traffic, and is arranged as a flat battery ( 9 ) below a floor of the travel trailer, in a vehicle frame ( 1 ), wherein the height of the battery ( 9 ) essentially corresponds to the height of the vehicle frame ( 1 ).

Claims (42)

1. A travel trailer comprising an interior, a floor of the interior that is designed to support standing and walking persons, a vehicle frame, a front battery, and a rear battery, wherein:

the floor of the interior lies on the vehicle frame;

the vehicle frame comprises a coupling head, wheels, an axle, longitudinal beams, inner beams, and transverse beams;

the longitudinal beams lie on the outside of the vehicle frame;

the inner beams are arranged between and are spaced from the longitudinal beams;

two of the transverse beams connect ends of the longitudinal beams to ends of the inner beams to form an inner frame; and

the front battery, the rear battery, and the axle are arranged along a common plane within the inner beams of the inner frame, on opposite sides of the axle, such that a spacing between the longitudinal beams that lie on the outside of the vehicle frame and the inner beams of the inner frame protects the front battery and the rear battery from damage.

2. The travel trailer of claim 1 , wherein the axle comprises a torsion tube.

3. The travel trailer of claim 1 , wherein the front battery and the rear battery are symmetrically positioned distribute weight about the axle.

4. The travel trailer of claim 1 , wherein a height of the inner frame generally corresponds to a height of the front battery and the rear battery.

5. The travel trailer of claim 1 , wherein the front battery or the rear battery supply electricity to a travel drive of a towing vehicle.

6. The travel trailer of claim 1 , wherein the front battery or the rear battery supply electricity to a travel drive of the travel trailer.

7. The travel trailer of claim 1 , wherein the front battery or the rear battery supply electricity to a travel drive of a towing vehicle or a travel drive of the travel trailer.

8. The travel trailer of claim 1 , wherein the inner beams abut the front battery and the rear battery.

9. The travel trailer of claim 1 , wherein the inner frame abuts the front battery and the rear battery.

10. A travel trailer comprising an interior, a floor of the interior that is designed to support standing and walking persons, a vehicle frame, a front battery, and a rear battery, wherein:

the floor of the interior lies on the vehicle frame;

the vehicle frame comprises a coupling head, wheels, an axle, longitudinal beams, inner beams, and transverse beams;

the longitudinal beams lie on the outside of the vehicle frame;

the inner beams are arranged between and are spaced from the longitudinal beams;

two of the transverse beams connect ends of the longitudinal beams to ends of the inner beams to form an inner frame; and

the front battery, the rear battery, and the axle are arranged along a common plane within the inner beams of the inner frame, on opposite sides of the axle, such that a spacing between the longitudinal beams that lie on the outside of the vehicle frame and the inner beams of the inner frame protects the front battery and the rear battery from damage, wherein:

the front battery and the rear battery are symmetrically positioned distribute weight about the axle; and

a height of the inner frame generally corresponds to a height of the front battery and the rear battery.

11. The travel trailer of claim 10 , wherein the axle comprises a torsion tube.

12. The travel trailer of claim 11 , wherein the inner frame abuts the front battery and the rear battery.

13. The travel trailer of claim 10 , wherein the front battery or the rear battery supply electricity to a travel drive of a towing vehicle.

14. The travel trailer of claim 10 , wherein the front battery or the rear battery supply electricity to a travel drive of the travel trailer.

15. The travel trailer of claim 10 , wherein the front battery or the rear battery supply electricity to a travel drive of a towing vehicle or a travel drive of the travel trailer.

16. The travel trailer of claim 10 , wherein the inner beams abut the front battery and the rear battery.

17. A travel trailer comprising an interior, a floor of the interior that is designed to support standing and walking persons, a vehicle frame, a front battery, and a rear battery, wherein:

the floor of the interior lies on the vehicle frame;

the vehicle frame comprises a coupling head, wheels, an axle, longitudinal beams, inner beams, and transverse beams;

the longitudinal beams lie on the outside of the vehicle frame;

the inner beams are arranged between and are spaced from the longitudinal beams;

two of the transverse beams connect ends of the longitudinal beams to ends of the inner beams to form an inner frame; and

the front battery, the rear battery, and the axle are arranged along a common plane within the inner beams of the inner frame, on opposite sides of the axle, such that a spacing between the longitudinal beams that lie on the outside of the vehicle frame and the inner beams of the inner frame protects the front battery and the rear battery from damage, wherein:

the front battery and the rear battery are symmetrically positioned distribute weight about the axle;

the front battery or the rear battery supply electricity to a travel drive of a towing vehicle or a travel drive of the travel trailer;

the inner frame abuts the front battery and the rear battery; and

a height of the inner frame generally corresponds to a height of the front battery and the rear battery.

18. The travel trailer of claim 17 , wherein the axle comprises a torsion tube.
