Abstract

A dynamic balancing device for the wheel of a motor vehicle, the device comprising flexibly mounted weighting members which are driven outward by the increased centrifugal forces diametrically opposite the nonconcentric mass center to produce the desired balancing effect.

Claims

1. A dynamic wheel balancer for mounting on a motor vehicle wheel between fits hub opening and a tire mounted on a rim of the wheel comprising:

a dynamic ring-shaped balancing means carried by said wheel in concentric relationship to its hub opening,

said means comprising a flat continuous band of flexible material stretched over the rim of the wheel,

said band being provided with a plurality of identical appendages equally spaced around the length of said band, and

each of said appendages having an identical enlarged head portion at the end of the appendage,

said head portion comprising a cylindrical body extending transversely across said band in a parallel arrangement with each head portion on the other of said appendages,

the head portion upon rotation of the wheel displacing radially of the hub opening of the wheel toward the side of the wheel diametrically opposite the hub opening from the mass center of the wheel to offset the initial imbalance of the wheel.

2. A dynamic wheel balancer for mounting on a motor vehicle wheel between its hub opening and a tire mounted on a rim of the wheel comprising:

a dynamic ring-shaped balancing means carried by said wheel in concentric relationship to its hub opening,

said means comprising a continuous member carried by the rim of the wheel,

said member being provided with a plurality of identical appendages equally spaced around the length of said member, and

each of said appendages having an identical enlarged head portion at the end of the appendage,

said head portion comprising a rounded body extending along said band in a parallel arrangement with each head portion on the other of said appendages.

3. A dynamic wheel balancer for mounting on a motor vehicle wheel between its hub opening and a tire mounted on a rim of the wheel comprising:

a dynamic ring-shaped balancing means carried by said wheel in concentric relationsip to its hub opening,

said means comprising a flat continuous band positioned over the rim of the wheel,

said band being provided with a plurality of identical appendages equally spaced around the length of said band, and

each of said appendages comprising a strap of metal, the free end of which is coiled in a common direction to form a spring which unwinds to offset the initial imbalance of the wheel,

each spring upon rotation of the wheel displacing radially of the hub opening of the wheel toward the side of the wheel diametrically opposite the hub opening from the mass center of the wheel to offset the initial imbalance of the wheel.

4. A dynamic wheel balancer or mounting on a motor vehicle wheel between its hub opening and a tire mounted on a rim of the wheel comprising:

a dynamic ring-shaped balancing means carried by said wheel in concentric relationship to its hub opening,

said means comprising a mass in the form of a continuous member surrounding said hub opening,

said mass upon rotation of the wheel displacing radially of the hub opening of the wheel toward the side of the wheel diametrically opposite the hub opening from the mass center of the wheel to offset the initial imbalance of the wheel,

said means comprising a coil spring the length of which extends around the rim of the wheel in a closed circular configuration, and

an endless band of wire arranged to extend through the center of said coil spring to constrain the maximum deflection of said coil spring from the surface of said rim.

5. A dynamic wheel balancer for mounting on a motor vehicle wheel between its hub opening and a tire mounted on a rim of the wheel comprising:

a dynamic ring-shaped balancing means carried by said wheel in concentric relationship to its hub opening,

said means comprising a mass in the form of a continuous member surrounding said hub opening,

said mass upon rotation of the wheel displacing radially of the hub opening of the wheel toward the side of the wheel diametrically opposite the hub opening from the mass center of the wheel to offset the initial imbalance of the wheel,

said balancing means being carried by the inside periphery of the rim, and

adjustment means for adjustably securihg said member to the inside periphery of the rim of the wheel.
