Abstract

Intake assemblies for an engine are provided. In one aspect, an air intake assembly includes a screen defining a plurality of air passage holes therein, a fan, a flywheel, a crankshaft, and a screen support member coupled to the screen. The fan, the flywheel and the screen support member are coupled to the crankshaft with a single fastener, and the screen, the fan, the flywheel, the crankshaft and the screen support member all rotate together. In one aspect, the screen support member supports the screen a distance away from the fan such that the screen is completely spaced-apart from and does not engage the fan. In one aspect, a screen support member includes a base near one end of the screen support member and a plurality of coupling locations near a second end. The screen couples to the screen support member at the plurality of coupling locations.

First claim

The invention claimed is:

1. An air intake assembly for an engine, the air intake assembly comprising:
a screen defining a plurality of air passage holes therein configured to allow passage of air through the screen and into the engine;
a fan;
a flywheel;
a crankshaft; and
a screen support member coupled to the screen, wherein the fan, the flywheel and the screen support member are coupled to the crankshaft with a single fastener, wherein the screen, the fan, the flywheel, the crankshaft and the screen support member all rotate together when coupled to the crankshaft with the single fastener;
wherein the screen support member includes a plurality of spaced-apart legs extending from the base, and wherein the screen is coupled to each of the plurality of spaced-apart legs with a fastener.

2. The air intake assembly of claim 1 , wherein the fan is compressed between the screen support member and the flywheel when coupled together with the single fastener.

3. The air intake assembly of claim 1 , wherein the crankshaft defines a threaded aperture and the single fastener is a single threaded fastener, and wherein the single threaded fastener passes through the fan and the flywheel without threading thereto and threadably engages the threaded aperture of the crankshaft.

4. The air intake assembly of claim 3 , wherein the fan is compressed between the screen support member and the flywheel when coupled together with the single threaded fastener.

5. The air intake assembly of claim 1 , wherein the screen is coupled to the screen support member in a plurality of locations.

6. The air intake assembly of claim 5 , wherein the screen is coupled to the screen support member in the plurality of locations with a plurality of fasteners.

7. The air intake assembly of claim 1 , wherein the screen, the fan, the flywheel, the crankshaft and the screen support member all rotate about a rotational axis, wherein the rotational axis extends through a longitudinal center of the single fastener.

8. The air intake assembly of claim 1 , wherein the single fastener is different than the fasteners used to couple the screen to the screen support member.

9. The air intake assembly of claim 1 , wherein at least one of the plurality of legs defines a hole therein.

10. The air intake assembly of claim 1 , wherein each of the plurality of legs defines a plurality of holes therein.

11. An air intake assembly for an engine, the air intake assembly comprising:
a screen defining a plurality of air passage holes therein configured to allow passage of air through the screen and into the engine;
a fan;
a flywheel;
a crankshaft; and
a screen support member coupled to the screen, wherein the fan, the flywheel and the screen support member are coupled to the crankshaft, wherein the screen, the fan, the flywheel, the crankshaft and the screen support member all rotate together, wherein the screen support member includes a plurality of spaced-apart legs extending from the base, and wherein the screen is coupled to each of the plurality of spaced-apart legs.

12. The air intake assembly of claim 11 , wherein the fan, the flywheel, and the screen support member are coupled to the crankshaft with a single fastener.

13. The air intake assembly of claim 11 , wherein the screen is coupled to each of the plurality of spaced-apart legs with a fastener.

14. The air intake assembly of claim 13 , wherein at least one of the plurality of legs defines a hole therein.

15. The air intake assembly of claim 13 , wherein each of the plurality of legs defines a hole plurality of holes therein.
