Specific embodiment

Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of Explanation.

As shown in Figure 1 to Figure 3, camber angle measuring device, including the survey for being placed on 8 highest point position of wheel Long rod 1 is measured, there is lifting rope 3 in one end system for measuring long rod 1, and the lower end of lifting rope is equipped with pendant 4.

Further, it measures and is equipped with size scale line along the length direction for measuring long rod on long rod 1.Long rod is measured to be equipped with Level meter, convenient for observing and measuring whether long rod is in horizontality.

Long rod is measured equipped with card slot, card slot is interior to be equipped with removable ruler 2, and ruler is easy to carry convenient for picking and placing, and Ruler is not easy to lose.

The camber angle measuring method, comprising the following steps:

Such as measure plane from 7 side of crown outer edge to formation and wheel disk 6 in lateral plane be in a plane Highly；

One end of a piece long rod 1 of measurement is placed on to the highest point of wheel, long rod is measured and is in a horizontal state placement, measure long rod Other end system have a lifting rope, the tenesmus of lifting rope lower end has pendant；The optional waste and old nut of pendant.

Measuring distance of the crown outer edge apart from vertical lifting rope by ruler 2 is A, measures wheel disk lateral distance and hangs down The distance of straight lifting rope is B；

It calculates camber angle α=arcsin ((A-B)/R), wherein R is the rolling radius of tire.

In addition, plane and wheel ornament that such as measurement crown outer edge is laterally formed cover on lateral plane not in a plane Highly, the plane that the plane relative wheel Decorative Cover that measurement crown outer edge is formed is formed is X in the offset of automobile Y-direction；

One end of a piece long rod of measurement is placed on to the highest point of wheel, long rod is measured and is in a horizontal state placement, measure long rod Other end system have a lifting rope, the tenesmus of lifting rope lower end has pendant；

Measuring distance of the crown outer edge apart from vertical lifting rope by ruler is A, measures wheel disk lateral distance and hangs down The distance of straight lifting rope is B；

It calculates camber angle α=arcsin ((A-B-X)/R), wherein R is the rolling radius of tire.

Long rod and cord can draw materials everywhere, and waste and old nut is also convenient for finding, ruler belongs to routine office work articles, and four groups Close can convenient and efficient completions camber angular measurement, exclude whether vehicle causes tire eccentric wear because of camber angle is unqualified.

Measuring device simple structure is easy to carry, and measurement can carry out whenever and wherever possible, measure it is easy to operate, can rapid survey go out Whether camber angle is qualified.

It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination Bright example scheme.
