ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an angle rotating device for wheel alignment test. More particularly, the present invention relates to an angle rotating device for wheel alignment test which can sense a deflection angle of a wheel sensitively.
Referring to
FIGS. 1
,
2
, and
2
A, an angle rotating device A for wheel alignment test of the prior art has a cover plate A
3
, a solid rotating disk A
1
disposed on the cover plate A
3
, a ring A
2
disposed in the solid rotating disk A
1
, a movable rack A
4
disposed on a bottom of the cover plate A
3
, and a movable plate A
5
confined by the movable rack A
4
. The solid rotating disk A
1
has a center shaft All. The ring A
2
has an annular face A
21
having a plurality of circular apertures receiving a plurality of balls A
22
. A sleeve A
24
is disposed in a center of the ring A
2
. A plurality of springs A
23
are connected to the sleeve A
24
and the ring A
2
. The cover plate A
3
has a center hole A
32
and a plurality of cage posts A
31
confining the movable rack A
4
. The movable rack A
4
has two transverse plates A
41
, two longitudinal plates A
42
, and a spacing A
43
defined by the transverse plates A
41
. The movable plate A
5
has a round hole A
51
. The spacing A
43
receives the movable plate A
5
. The center shaft All passes through the sleeve A
24
, the center hole A
32
, and the round hole A
51
. Referring to
FIG. 1
again, a wheel B presses the angle rotating device A for wheel alignment test of the prior art. Since the cage posts A
31
contact the movable rack A
4
, the friction between the cage post A
31
and the movable rack A
4
will be very large. Therefore, the angle rotating device A for wheel alignment test cannot sense a deflection angle of the wheel B sensitively.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an angle rotating device for wheel alignment test which can sense a deflection angle of a wheel sensitively.
Accordingly, an angle rotating device for wheel alignment test comprises a disk seat, a lever bar inserted in the disk seat, a cover plate covering the disk seat, a solid rotating disk disposed on the cover plate, a ring disposed in the solid rotating disk, and a hollow disk disposed in the cover plate. The disk seat has a sector recess, two arc recesses, a center groove, a round aperture, and a center aperture. The lever bar has an oblong hole, a round hole, and a circular hole. The hollow disk has a center through hole. The cover plate has a round opening receiving an upper portion of the hollow disk. The solid rotating disk has a center shaft. The ring has a central hole, an annular face having a plurality of circular apertures receiving a plurality of balls. A sleeve is disposed in the central hole of the ring. A plurality of springs are connected to the sleeve and the ring. The sector recess of the disk seat receives the lever bar. The circular hole of the lever bar matches the round aperture of the disk seat. A bolt is inserted in the round hole of the lever bar. The center shaft passes through the sleeve, the center through hole, and the oblong hole.
