Abstract

A motorcycle includes an internal combustion engine, a frame, a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and a container connected to the internal combustion engine and the fuel tank. The container is configured to store fuel evaporating from the fuel tank, and the container in a position of use is at least partially covered by the fuel tank. The fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use.

First claim

The invention claimed is:

1. A motorcycle including:
an internal combustion engine,
a frame,
a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and
a container connected to the internal combustion engine and the fuel tank, wherein the container is configured to store fuel evaporating from the fuel tank,
wherein the container in a position of use is at least partially covered by the fuel tank, and the fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use, and
wherein the container is fixed to the fuel tank at an underside or at a front side or at an underside and a front side of the fuel tank and is pivotable jointly with the fuel tank.

2. The motorcycle as set forth in claim 1 , wherein the fuel tank is mounted to the motorcycle pivotably by a joint connection.

3. The motorcycle as set forth in claim 2 , wherein the joint connection is a hinge.

4. The motorcycle as set forth in claim 1 , wherein the fuel tank is mounted pivotably about an axis arranged perpendicularly to a longitudinal axis of the motorcycle.

5. The motorcycle as set forth in claim 1 , wherein the fuel tank is mounted pivotably to the frame.

6. The motorcycle as set forth in claim 1 , wherein the container is connected to a feed line or a discharge line or a feed line and a discharge line, the container and fuel tank being configured such that fuel evaporating in the fuel tank is passed by the feed line to the container and fuel in operation of the motorcycle is passed by the discharge line from the container to the internal combustion engine, and the feed line or the discharge line or the feed line and the discharge line is or are fixed to the fuel tank.

7. The motorcycle as set forth in claim 6 , further comprising an entire emission system fixed to the fuel tank.

8. The motorcycle as set forth in claim 1 , wherein the motorcycle has a steering system, and the fuel tank is mounted pivotably on the side of the fuel tank remote from the steering system.

9. The motorcycle as set forth in claim 1 , wherein the motorcycle has a saddle adjoining the fuel tank, and the fuel tank is mounted pivotably in the region of the saddle.

10. The motorcycle as set forth in claim 1 , wherein the motorcycle has a frame having lateral elements at left-hand and right-hand sides as viewed in a direction of travel, the container being arranged between the lateral elements.

11. The motorcycle as set forth in claim 10 , wherein the frame is a double-tube frame, each of the lateral elements has a top frame tube and a base frame tube, and the container in the position of use of the fuel tank is arranged between the top frame tube and the base frame tube.

12. The motorcycle as set forth in claim 11 , wherein the frame is a trellis tube frame.

13. The motorcycle as set forth in claim 1 , wherein the container is cylindrical.

14. The motorcycle as set forth in claim 1 , wherein the container is arranged such that a longitudinal direction of the container is perpendicular to a longitudinal direction of the motorcycle.

15. The motorcycle as set forth in claim 1 , wherein the container in the fixed state has a longitudinal length of between 20% and 90% of a width of the fuel tank.

16. The motorcycle as set forth in claim 15 , wherein the longitudinal length of the container in the fixed state is between 30% and 60% of the width of the fuel tank.

17. The motorcycle as set forth in claim 1 , wherein the container in the position of use is arranged partially or entirely above the lower end of the fuel tank.

18. The motorcycle as set forth in claim 1 , wherein the container in the position of use in the lateral direction is arranged partially or entirely behind a notional vertical plane at the front end of the fuel tank.

19. A motorcycle including:
an internal combustion engine,
a frame,
a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and
a container connected to the internal combustion engine and the fuel tank, wherein the container is configured to store fuel evaporating from the fuel tank,
wherein the container in a position of use is at least partially covered by the fuel tank, and the fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use, and
wherein the pivotable mounting of the fuel tank is provided in a first half of the fuel tank, and the container is fixed to the fuel tank on a second half of the fuel tank.

20. A motorcycle including:
an internal combustion engine,
a frame,
a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and
a container connected to the internal combustion engine and the fuel tank, wherein the container is configured to store fuel evaporating from the fuel tank,
wherein the container in a position of use is at least partially covered by the fuel tank, and the fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use, and
wherein the pivotable mounting of the fuel tank is provided at a first end region of the fuel tank, and the container is fixed to the fuel tank at a second end region of the fuel tank opposite to the first end region.

21. A motorcycle including:
an internal combustion engine,
a frame,
a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and
a container connected to the internal combustion engine and the fuel tank, wherein the container is configured to store fuel evaporating from the fuel tank,
wherein the container in a position of use is at least partially covered by the fuel tank, and the fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use,
wherein the fuel tank is connected to the container by a feed line, and the container is fixed to the fuel tank at a position of the fuel tank relative to the feed line such that, upon a pivotal movement of the fuel tank into the maintenance position, a feed flow of liquid fuel into the container is prevented.

22. A motorcycle including:
an internal combustion engine,
a frame,
a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and
a container connected to the internal combustion engine and the fuel tank, wherein the container is configured to store fuel evaporating from the fuel tank,
wherein the container in a position of use is at least partially covered by the fuel tank, and the fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use,
wherein the container is fixed to the fuel tank by a metallic clip or an elastic fixing member or a metallic clip and an elastic fixing member.
