Abstract

A wheel fixing device for a wheel balancer, by which all types of vehicle wheels can be mounted in a simple manner between a flange portion of an adapter and a push member which includes a plurality of links, each link having a pin for holding a vehicle wheel, the number and the position of the pin being changed according to the type of the wheel.

Claims

1. A wheel fixing device for a wheel balancer having an axle, comprising:

an adaptor comprising a shaft portion which is attached to the end surface of the axle and extends coaxially from the axle, and a flange portion which is adjacent to the end surface of the axle;

an adaptor mounting means for mounting coaxially the adaptor to the axle;

a push member which is slidably fitted on the shaft portion of the adaptor, which has an annular groove facing the flange portion in its outside portion, and which includes a plurality of mounting holes arranged inside of the annular groove at the same distance from the axis of the adaptor;

a coupling ring which is fitted into the annular groove of the push member and includes a plurality of slots arranged radially corresponding to the mounting holes in number and position;

a plurality of links, each being provided with a first pin which is attached to one corner of the link and is fitted into the mounting hole, and a second pin which is fitted into the slot of the coupling ring, which are pivoted around the first pin by rotating the coupling ring;

a plurality of third pins for holding a vehicle wheel attached to the other corner of the link and facing the flange portion; and

a closing handle which is screwed on the shaft portion of the adaptor and closes the adaptor to the flange portion thereof so that the wheel may be secured between the push member and the flange portion of the adaptor.

2. A wheel fixing device according to claim 1, wherein each of the third pins attached to the links is interchangeable.

3. A wheel fixing device according to claim 1, further including an annular spring means having projection kinks projecting outwards, for rataining the coupling ring and the first pin, which is inserted into a circular groove formed around the inner periphery of the annular groove of the push member, and the projection kinks engaging in a circular groove formed in the inside surface of the coupling ring.

4. A wheel fixing device according to claim 3, wherein each of the third pins attached to the links is interchangeable.

5. A wheel fixing device according to claim 1 or claim 3, wherein the adaptor mounting means is a screwed rod having a pivotable handle in its free end, which runs through the center of the shaft portion of the adaptor and screwed to the end of the axle.

6. A wheel fixing device according to claim 5, wherein each of the third pins attached to the links is interchangeable.
