Description

WHEEL RIM DIAMETER MEASUREMENT SUBSIDIARY EQUIPMENT

The present invention relates to an auxiliary device for wheel rim measurement, and more particularly to a wheel rim measuring device capable of measuring an aluminum alloy wheel rim which can not be measured by a general measuring device.

Automobiles generally come into contact with the ground using vehicle wheels. These wheels consist of a wheel rim and a tire mounted on the wheel rim. Generally, the power of the vehicle is transmitted to the ground via the wheel. As a result, the wheel rim and the tire are subjected to a very large force.

Therefore, the wheel rim and the tire must be firmly coupled to each other to ensure the safety of the occupant. For this purpose, wheel rims and tires must be manufactured to the same dimensions.

Wheel rims are classified according to their shape. In passenger cars, a drop center rim is used in many cases. The drop-center rim can be produced symmetrically or asymmetrically. In large commercial vehicles, a semi-drop center rim, in which the rim is divided into several pieces, is mainly used.

The wheel rim is a part that closely contacts the tire, and it is an important part to maintain air pressure. The width of the wheel rim is closely related to the flatness ratio of the tire. When the rim width is small, the side wheel portion is exposed and the risk is increased. In addition, when the rim width is large, the fuel consumption is increased and it may cause interference with the vehicle body.

In addition, the rim components include hump and bead seat.

It is difficult to measure the wheel rimmer with the general measuring machine, and it is possible to measure only by the coordinate measuring machine (CMM) which is a three-dimensional measuring machine.

In the case of measuring with a three-dimensional measuring equipment, there is a problem that a moving time and a measuring time of the product are increased.

Also, the measurement by the three-dimensional measuring apparatus uses a method of measuring the radius value from the center to the outer diameter portion and converting it into a diameter. This may cause an error depending on the position measured due to the roundness value of the wheel. To reduce this error, several points are measured and the average value is calculated.

As a general measuring instrument, a method of measuring the other part such as the outer diameter including the flange or measuring the bead sheet is used to derive a result value by a calculation formula. The measurement of the outer diameter portion of the wheel and the measurement of the bead seat using the general measuring instrument can not be directly measured, which causes an error due to the calculation.

In order to solve this problem, a study was made on a device capable of directly measuring the area of the wheel rim.
