Rim assembly with oscillator
View Patent ↗A rim assembly comprises a rim including a peripheral rim portion for the mounting of a wheel; a wheel cover affixed to the rim and configured to rotate about an axis of the rim; and an oscillator attached to the wheel cover and configured to move back and forth between a first position and a second position based on rotation of the wheel cover about the axis. The oscillator is configured to protract axially away from the wheel cover when moving from the second position toward the first position and to retract axially toward the wheel cover when moving from the first position toward the second position.
1. An assembly, comprising:
(a) a wheel cover; and
(b) an oscillator attached to said wheel cover and configured to move back and forth between a first position and a second position based on rotation of the wheel cover about an axis thereof;
(c) a spring member that biases said oscillator toward the first position from the second position;
(d) wherein
(i) said oscillator is configured to protract axially away from said wheel cover when moving from the second position toward the first position and to retract axially toward said wheel cover when moving from the first position toward the second position, and
(ii) said oscillator is configured to move from the first position toward the second position based on centrifugal force.
2. The assembly of claim 1 , further comprising a rim including a peripheral rim portion for the mounting of a tire, wherein the wheel cover is affixed to said rim.
3. The assembly of claim 1 , wherein said oscillator is one of a plurality of oscillators and wherein said spring member biases each of the oscillators.
4. The assembly of claim 1 , wherein said oscillator is one of a plurality of oscillators and wherein said spring member is one of a plurality of spring members, each spring member biasing a respective one of the plurality of oscillators.
5. An assembly, comprising:
(a) a wheel cover; and
(b) an oscillator attached to said wheel cover and configured to move back and forth between a first position and a second position based on rotation of the wheel cover about an axis thereof;
(c) a spring member that biases said oscillator toward the first position from the second position;
(d) wherein
(i) said oscillator is configured to protract axially away from said wheel cover when moving from the second position toward the first position and to retract axially toward said wheel cover when moving from the first position toward the second position, and
(ii) said oscillator is configured such that when the wheel cover is at rest, said oscillator is in the first position, and further configured to transition to the second position as a result of an increase in an angular velocity of the wheel cover.
6. The assembly of claim 5 , further comprising a rim including a peripheral rim portion for the mounting of a tire, wherein the wheel cover is affixed to said rim.
7. A vehicle including the assembly of claim 5 .
8. A rim assembly, comprising:
(a) a rim and a wheel cover affixed to said rim; and
(b) an oscillator attached to said wheel cover and configured to move back and forth between a first position and a second position based on rotation of the wheel cover about an axis thereof;
(c) a spring member that biases said oscillator toward the first position from the second position;
(d) wherein
(i) said oscillator is configured to protract axially away from said wheel cover when moving from the second position toward the first position and to retract axially toward said wheel cover when moving from the first position toward the second position, and
(ii) said rim assembly is configured such that when said wheel cover is affixed to a rim and said oscillator is in the first position, said oscillator extends axially outward from the wheel cover.
9. The rim assembly of claim 8 , wherein said rim includes a peripheral rim portion for the mounting of a tire.
10. An assembly, comprising:
(a) a wheel cover;
(b) an oscillator attached to said wheel cover and configured to move back and forth between a first position and a second position based on rotation of the wheel cover about an axis thereof; and
(c) a weight that is affixed to said oscillator;
(d) a spring member that biases said oscillator toward the first position from the second position;
(e) wherein said oscillator is configured to protract axially away from said wheel cover when moving from the second position toward the first position and to retract axially toward said wheel cover when moving from the first position toward the second position.
11. The assembly of claim 10 , wherein said weight is removably affixed to said oscillator.
12. The assembly of claim 10 , further comprising a rim including a peripheral rim portion for the mounting of a tire, wherein the wheel cover is affixed to said rim.
