Description of drawings
Fig. 1 is a structural representation of the present invention;
The steering angle scheme drawing that Fig. 2 is (a) and (b), (c), (d), (e), (f), (g) is different with (h).
The specific embodiment
Steering angle memory indicating means of the present invention is that the steering angle memory display disc is set on tested rotating body, and by the position of movable weight in the steering angle memory display disc cavity, turning to and corner of tested rotating body indicated in memory.
As shown in Figure 1, a kind of steering angle memory display disc of design-calculated as stated above, by a flat box body 1 be located at can constitute by free-moving weight 2 in the box body 1, be provided with the snail curve cavity 3 of symmetry in the box body 1, weight 2 is located in the described cavity 3; The sinuousness of described spiral curve is 630 degree to the maximum.During use, if box body and horizontal surface inclination is in a certain angle, and be positioned can remember turning to and corner of display disc on a certain rotatable dish.When display disc rotates along with rotating disc and when rotating, can free-moving weight 2 will be in the spiral curve cavity free motion of the effect lower edge of gravity; When rotating disc stopped operating, display disc also stopped operating thereupon, and movable thing (heavy ball) 2 is stop motion, and rested on a certain position of curve cavity, thereby remembered turning to and corner of display disc.Wherein, movable weight 2 can be solid, as steel ball; Or be liquid, as mercury or colored water etc.
Be the principle of work of example explanation steering angle memory display disc below with the vehicle steering.
Before the installation, bearing circle just being returned, is that bead is positioned at Fig. 1 position display disc is sticked on the bearing circle by the state of Fig. 1.
When steering wheel rotation, display disc is along with bearing circle rotates with angle, because bead can freely roll along the cavity curve plane and be subjected to the effect of terrestrial gravitation simultaneously, bead is positioned at the relative low spot of cavity curve all the time, bead is positioned at the diverse location of cavity curve plane, represented direction about and angle: when bearing circle returns timing, bead is positioned at Fig. 2 (a) position.
