Abstract
The utility model discloses a steering wheel marker device with a steering indication function. A steering wheel is connected with a sun wheel of a planetary gear, the sun wheel rotates simultaneously along with the steering wheel, a counter weight is connected under a gear ring, and a marker is fixed on a planetary frame. By means of the inclination of the steering wheel and the counter weight under the gear ring, the gear ring does not rotate simultaneously along with the steering wheel, and when the sun wheel rotates along the steering wheel, the planetary frame rotates in a homodromous deceleration mode. The steering angle of the marker is set by setting the gear ratio between the gear ring and the sun wheel, the maximum steering angle of the marker is smaller than 180 degrees, and therefore a driver can clearly see the steering angle by viewing the marker, and learn steering conditions of front wheels. A centrifugal valve is arranged between the sun wheel and the gear ring, the sun wheel can freely rotate relative to the gear ring, but the gear ring can not freely rotate relative to the sun wheel, and therefore the situation that the marker is disordered in indication caused by manual pushing in the use process when vehicles are in a stationary state can be avoided.
Description
Affiliated technical field
The utility model relates to a kind of direction jiggering device for mark with steering indicating function.
Background technology
At present, bearing circle is got on the bus to mark and is directly fixed on the bearing circle shell, and the car mark rotates simultaneously with bearing circle.Because wheel steering angle is greater than 180 degree, navigating mate can't by the Reading the Tape mark, be confirmed the front-wheel steering angle.Particularly when stopping, a lot of people need see that wheel knows just whether bearing circle just returns.
Summary of the invention
Rotate simultaneously with bearing circle in order to overcome the dish mark, the dish mark can not be indicated the deficiency of front-wheel steering situation, the utility model provides a kind of direction jiggering device for mark with steering indicating function, and this car device for mark can not only turn to situation by the direction indication dish, and does not affect the bearing circle overall appearance.
The technical scheme that its technical matters that solves the utility model adopts is: bearing circle is connected with planetary sun wheel, and sun wheel is rotated simultaneously with bearing circle, and the gear ring below connects a counterweight, and the dish mark is fixed on the pinion carrier.Utilize the inclination of bearing circle and gear ring below counterweight, gear ring is not rotated simultaneously with bearing circle, when sun wheel during with rotating of steering wheel, rotation will occur to slow down in the same way in pinion carrier.By setting the ratio of number of teeth of gear ring and sun wheel, come assignment disk mark steering angle, make dish mark steering locking angle degree less than 180 degree, the personnel that drive thus can by Reading the Tape mark steering angle, understand the front-wheel steering situation.Be provided with centrifugal valve between sun wheel and the gear ring, sun wheel can freely be rotated relative to gear ring, but gear ring can not freely rotate relative to sun wheel, can avoid vehicle under static state like this, and artificial shifting disc mark causes the indication of use procedure mid-game mark chaotic.
The beneficial effects of the utility model are, navigating mate can be known the front-wheel steering situation by seeing direction jiggering mark steering angle, and apparatus body is one group of planetary wheel, and is simple in structure.

The specific embodiment
Among Figure 21, direction jiggering device for mark is placed the bearing circle center.
Among Figure 22, gear ring (5) is linked as an integral body with counterweight (7) by welding.
Among Figure 20, when rotating of steering wheel, because attaching parts (2) links together by bolt (3) and bearing circle shell (1), attaching parts (2) will rotate simultaneously with the aspect dish, and attaching parts (2) top institute's centrifugal valve of putting (9) and sun wheel (10) also will be rotated simultaneously with bearing circle.Gear ring (5) is connected by circular hole with attaching parts (2), and under the effect of counterweight (7), gear ring (5) will not rotate with attaching parts (2) simultaneously; Attaching parts (2) and gear ring (5), gear ring (5) becomes friction of rolling by steel ball A (4), steel ball B (6) with cliding friction with the main contact surface of centrifugal valve (9), with the friction force that reduces to bring to gear ring (5) in attaching parts (2), centrifugal valve (9) rotation process, further guarantee the not rotation of gear ring (5).
The rotation of sun wheel (10), and the not rotation of gear ring (5) must cause the rotation of satellite gear (11), pinion carrier (12), utilize the planetary gear speed-reduction principle, and pinion carrier (12) relative direction dish will be the rotation of slowing down in the same way.Because car label (14) is fixed on the pinion carrier (12) by double faced adhesive tape (13), car label (14) relative direction dish also will be the rotation of slowing down in the same way.
Among Fig. 8, under the normal condition, metal ball (8) is sunken to the bottom under Action of Gravity Field, do not affect the rotation of centrifugal valve (9), sun wheel (10).Among Fig. 9, when bearing circle static, it is quiescence that centrifugal valve (9) also will be in, to cause the rotation of gear ring (5) such as the people for stirring car label (14), drive the rotation of counterweight (7), when counterweight (7) when rotational angle is large, metal ball (8) will roll out from the bottom, be stuck between centrifugal valve (9) and the counterweight (7), cause the people can not continue to stir car label (14); Among Fig. 9, when unclamping, staff no longer stirs car label (14), counterweight (7) is under Action of Gravity Field, to sink, metal ball (8) falls within counterweight (7) bottom again, no longer be stuck between centrifugal valve (9) and the counterweight (7), counterweight (7) is under gravity continuation effect, and whole device will be back to normal condition again.Like this, just can prevent from artificially dialling random car label (14), cause the situation of car label (14) mal direction indication to occur.
According to conservation of energy theorem, obtain the characteristic equation of planetary wheel motion:
n
1+an
2-(1+a)n
3＝0
n
1-sun wheel rotating speed, n
2-gear ring rotating speed, n
3=pinion carrier rotating speed, a-gear ring and sun wheel number of teeth ratio.
This device gear ring (5) has not rotation, so n
2=0.
Pinion carrier (12) rotation speed n
3=n
1/ (1+a)
Draw thus by setting the ratio of number of teeth of gear ring (5) and sun wheel (10), set the deceleration situation of car label (14).As: when the ratio of number of teeth of gear ring (5) and sun wheel (10) was 4, when rotating of steering wheel 720 degree, car label (14) was with rotating in same direction 144 degree.By realizing a bit by the label of looking out for the car (14) steering angle, understand the front-wheel steering situation.
