Abstract

An intake device is provided for the combustion air of a motorcycle, including an air filter box and an air guide intake duct which extends from the air filter box in a defined orientation to an intake chamber and at least sections of which are formed by parts of the air filter box.

Claims

1. An intake device for combustion air in a motorcycle, comprising: an air filter box; and an air guide intake duct, wherein: the motorcycle has a drive assembly swing arm with at least one side trim part and wherein the drive assembly swing arm defines an intake cavity, and the air guide intake duct is formed in a formally integrated manner from parts of the side trim part and the air filter box, wherein the air guide intake duct and the air filter box are configured in one piece, and wherein the air guide intake duct extends from the air filter box in a fixed orientation to the intake cavity of the drive assembly swing arm.

2. The intake device according to claim 1, wherein, in an installed state, the air guide intake duct is oriented toward the ground in a range from 45 degrees to +45 degrees with respect to a vertical line.

3. The intake device according to claim 2, wherein the air guide intake duct extends into the air filter box over a predefined length.

4. The intake device according to claim 1, wherein, in an installed state, the air guide intake duct is oriented toward the ground in a range from 15 degrees to +15 degrees with respect to a vertical line.

5. The intake device according to claim 4, wherein the air guide intake duct extends into the air filter box over a predefined length.

6. The intake device according to claim 1, wherein, in an interior, the air guide intake duct has fan elements which collect and return moisture which is sucked in before reaching the air filter box.

7. The intake device according to claim 1, wherein the air guide intake duct extends into the air filter box over a predefined length.

8. An intake device for combustion air in a motorcycle, comprising: an air filter box; and an air guide intake duct which extends from the air filter box in a fixed orientation to an intake space, the air guide intake duct being formed at least in sections by parts of the air filter box, wherein, in an interior, the air guide intake duct has fan elements which collect and return moisture which is sucked in before reaching the air filter box.

9. The intake device according to claim 8, wherein the fan elements are configured in one piece on the air guide intake duct.

10. A motor scooter, comprising: a drive assembly swing arm having an integrated intake cavity; and an intake device for combustion air in the motor scooter, the intake device being arranged on the drive assembly swing arm and comprising: an air filter box, and an air guide intake duct which extends from the air filter box in a fixed orientation to the intake cavity of the drive assembly swing arm, the air guide intake duct being formed in a formally integrated manner from parts of a side trim part of the drive assembly swing arm and parts of the air filter box, wherein the air guide intake duct and the air filter box are configured in one piece.

11. The motor scooter according to claim 10, wherein the air guide intake duct is oriented toward the ground in a range from 45 degrees to +45 degrees with respect to a vertical line.

12. The motor scooter according to claim 10, wherein the air guide intake duct is oriented toward the ground in a range from 15 degrees to +15 with respect to a vertical line.

13. The motor scooter according to claim 10, wherein the air guide intake duct comprises fan elements in an interior thereof which collect and return moisture that is sucked in before reaching the air filter box.

14. The motor scooter according to claim 13, wherein the fan elements are configured in one piece on the air guide intake duct.

15. The motor scooter according to claim 10, wherein the air guide intake duct extends into the air filter box over a predefined length.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a side view of an intake device according to the invention in a first embodiment, and

(2) FIG. 2 is a side view of an intake device according to the invention in a second embodiment.

(3) Identical designations denote identical parts in all the figures.

DETAILED DESCRIPTION OF THE DRAWINGS

(4) FIG. 1 shows a side view of an intake device which is integrated into a vehicle. The intake device has an air filter box 1 and an air guide intake duct 2 which extends from the air filter box 1 in an orientation at an angle 4 of +15 degrees with respect to a vertical line VL to an intake space in the vehicle interior and is formed in sections by parts of the air filter box 1. The air guide intake duct 2 is not only formed partially by the air filter box 1, but rather also extends into it. In the embodiment which is shown, the air filter box 1 and the air guide intake duct 2 are configured in one piece. The combustion air which is sucked in by the engine 6 leaves the air filter box 1 via a connecting line 7 to the engine 6.

(5) FIG. 2 shows a side view of a further intake device according to the invention in a second exemplary embodiment. The air guide intake duct 2 extends from the air filter box 1 in an orientation at an angle 4 of +45 degrees with respect to a vertical line VL to an intake cavity 5 which is formed in the drive assembly swing arm 3.

(6) Fan elements 2A shown in FIG. 1 are provided in both embodiments in the interior of the air guide intake duct 2, which fan elements form a labyrinth for water separation from the combustion air which is sucked in.

(7) The implementation of the invention is not restricted to the preferred exemplary embodiments which are specified above. Rather, a number of variants are conceivable which make use of the described solution even in the case of embodiments of fundamentally different type. For example, the air filter box and the air guide intake duct are preferably formed from the same material.

(8) The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
