Abstract

A tire fitting device includes: an arm for moving toward a tire; a striking roller for applying a striking force in the vicinity of a bead part, the striking roller being attached to the arm; a receiving roller for receiving the tire to which the striking force is applied; and an elastic member for elastically supporting the receiving roller.

First claim

The invention claimed is:

1. A fitting device for a tire assembly, which applies a striking force in vicinity of a pair of bead portions of a tire assembled onto a wheel, so as to increase adhesion between the wheel and the tire, comprising:
an arm configured to move toward the tire;
a striking roller attached to the arm and configured to apply a striking force in vicinity of the bead portions;
a receiving roller configured to receive the tire to which the striking force is applied; and
an elastic member configured to elastically support the receiving roller;
wherein, within vicinity of the pair of bead portions, the striking force is applied, by the striking roller, in vicinity of one of the bead portions, and a reaction force is applied, by the receiving roller, in vicinity of the other bead portion.

2. A fitting device for a tire assembly, which applies a striking force in vicinity of a pair of bead portions of a tire assembled onto a wheel, so as to increase adhesion between the wheel and the tire, comprising:
an arm configured to move toward the tire;
a striking roller attached to the arm and configured to apply a striking force in vicinity of the bead portions;
a receiving roller configured to receive the tire to which the striking force is applied; and
an elastic member configured to elastically support the receiving roller;
wherein, within vicinity of the pair of bead portions, the striking force is applied, by the striking roller, in vicinity of one of the bead portions, whereby the receiving roller that receives the tire vibrates up and down.

3. The fitting device for a tire assembly according to claim 1 , wherein the elastic member is a compressible fluid pressure cylinder.

4. The fitting device for a tire assembly according to claim 1 , wherein the elastic member comprises a damper in which a non-compressible fluid is sealed, and a spring configured to press the receiving roller back to the vicinity of the other bead portion.

5. A fitting method for a tire assembly, in which a striking force is applied in vicinity of a pair of bead portions of a tire assembled onto a wheel, so as to increase adhesion between the wheel and the tire, comprising the steps of:
placing the tire on a receiving roller that is elastically supported by an elastic member,
applying a striking force in vicinity of one of the bead portions, by a striking roller that is provided on an arm configured to move toward the tire placed on the receiving roller; and
applying a reaction force by the receiving roller in vicinity of the other bead portion, the reaction force having a magnitude corresponding to a combination of the wheel and the tire, and a magnitude of the striking force by the striking roller.
