Continuously variable transmission clutch sheave cover
A continuously variable transmission clutch sheave cover is a one-piece plastic member having a plurality of snap-fit fasteners located between an outer perimeter and a central opening. The snap-fit fasteners releasably engage features positioned on the face of an outer sheave of a driven clutch assembly.
1. A continuously variable transmission clutch sheave cover, comprising:
a one-piece plastic member covering structural members on the face of an outer sheave of a driven clutch assembly having an inner sheave that is moveable relative to the outer sheave to continuously vary a drive ratio while rotating together with the outer sheave, the one-piece plastic member having an outer perimeter, a central opening, and a plurality of snap-fit fasteners that are integral with the one-piece plastic member and are located radially between the outer perimeter and the central opening.
2. The continuously variable transmission clutch sheave cover of claim 1 wherein the features on the face of the outer sheave are a plurality of pins, the snap-fit fasteners releasably engaging the pins.
3. The continuously variable transmission clutch sheave cover of claim 2 wherein the pins on the face of the outer sheave are between a plurality of structural members on the face of the outer sheave of the driven clutch assembly.
4. The continuously variable transmission clutch sheave cover of claim 1 , wherein the plurality of snap-fit fasteners are symmetrically located on the one-piece plastic member.
5. A continuously variable transmission clutch sheave cover, comprising
a one-piece plate-shaped member covering a plurality of structural members on an outer sheave of a driven clutch assembly having an inner sheave that is moveable relative to the outer sheave to continuously vary a drive ratio while rotating with the outer sheave;
a plurality of snap-fit fasteners that integrally extend from the one-piece plate-shaped member between a central opening and an outer perimeter to releasably engage a plurality of features on the outer sheave located between the plurality of structural members on the outer sheave, the snap-fit fasteners being the only fastening between the one-piece plate-shaped member and the outer sheave.
6. The continuously variable transmission clutch sheave cover of claim 5 , wherein the snap-fit fasteners are between an outer perimeter and a central opening in the plate-shaped member.
7. A continuously variable transmission clutch sheave cover, comprising:
a one-piece plate-shaped member that is manually engageable to an outer sheave of a driven clutch assembly by pressing the plate-shaped member against the outer sheave to engage a plurality of snap-fit fasteners on the one-piece plate shaped member which are the only fasteners to the outer sheave;
the one-piece plate-shaped member rotating with the outer sheave and with an inner sheave of the driven clutch assembly that is moveable relative to the outer sheave to continuously vary a drive ratio, and covering a plurality of radially extending structural members on the outer sheave, and covering a plurality of features engaging the plurality of snap-fit fasteners between the structural members.
8. The continuously variable transmission clutch sheave cover of claim 7 , wherein the plurality of snap-fit fasteners are symmetrically located on the plate-shaped member.
