Motorcycle intake air guide for a motorcycle engine
View Patent ↗A motorcycle intake air guide for guiding an intake air volumetric flow from a front region of a motorcycle to a motorcycle internal combustion engine includes a front air guiding duct, a rear air guiding duct arranged downstream of the front air guiding duct, and a steering head bypass region arranged between and connecting the front and the rear air guiding ducts to one another. The front and the rear air guiding ducts have a closed profile. The steering head bypass region preferably has, in a steering head cross-sectional plane which is arranged orthogonally with respect to a main flow direction of the intake air volumetric flow in the steering head bypass region, a non-closed profile for guiding the intake air volumetric flow around a steering head recess through which a steering head of the motorcycle extends. The steering head may close the non-closed profile at the steering head recess.
1. A motorcycle intake air guide for guiding an intake air volumetric flow from a front region of a motorcycle to a motorcycle internal combustion engine, comprising:
an air inlet;
a front air guide duct adjoining the air inlet downstream in relation to a flow direction of the intake air volumetric flow;
a rear air guide duct arranged downstream from the front air guide duct, the rear air guide duct feeding the intake air volumetric flow to an air outlet; and
a steering head flow-around region arranged between and connecting the front and the rear air guide ducts to one another in relation to the intake air volumetric flow,
wherein
the front and the rear air guide ducts each have a closed profile for guiding the intake air volumetric flow,
a flow cross-section area of the front air guide duct immediately upstream of the steering head flow-around region is essentially equal to a flow cross-section area of the rear air guide duct immediately downstream of the steering head flow-around region,
the steering head flow-around region is passes the intake air volumetric flow around a portion of a steering head of the motorcycle that extends through a steering head recess in the steering head flow around region, and
the steering head flow-around region at the steering head recess has a non-closed profile for guiding the intake air volumetric flow adjacent to the steering head that cooperates with the steering head to form a closed profile.
2. The motorcycle intake air guide as claimed in claim 1 , wherein
the steering head flow-around region has a C-shaped profile adjacent to the steering head recess.
3. The motorcycle intake air guide as claimed in claim 1 , wherein
the steering head flow-around region has a first branch and a second branch, and
the first and second branches begin on a front air guide duct side of the steering head flow-around region, pass on opposite sides of the steering head recess, and recombine on a rear air guide duct side of the steering head flow-around region.
4. The motorcycle intake air guide as claimed in claim 3 , wherein
the first and second branches each have a C-shaped profile adjacent to the steering head recess, and
limbs of the C-shaped profile of the first branch and limbs of the C-shaped profile of the second branch on opposite sides of the steering head recess are oriented toward one another.
5. The motorcycle intake air guide as claimed in claim 4 , wherein
the motorcycle intake air guide is configured in multiple pieces.
6. The motorcycle intake air guide as claimed in claim 5 , wherein
the steering head flow-around region includes a front intake air guide portion and a rear intake air guide portion.
7. The intake air guide as claimed in claim 6 , wherein
the front and the rear intake air guide portions are connect to one another.
8. The intake air guide as claimed in claim 7 , wherein
the front and the rear intake air guide portions connect to one another by a latching connection.
