Abstract
The utility model discloses a motor vehicle direction navigating instrument. A circular dial with a center hole is installed on a center shaft in a movable fit mode. A counter weight is fixedly installed at the portion, on the back side of the dial, of the center shaft. A fixedly-installed gear disc, a movably-installed counting gear disc and a pointer which is fixedly installed at the end of the center shaft are sequentially arranged at the portion, on the front side of the dial, of the center shaft. The motor vehicle direction navigating instrument is simple in structure, reasonable in design, convenient to install, accurate in display and beneficial to a driver to clearly master the deviation angles of vehicle wheels and the rotation turn number of a steering wheel during running of a motor vehicle, and guarantees the safety traffic of the motor vehicle.
Description
Technical field
The utility model relates to a kind of navigating instrument, specifically a kind of vehicle directional navigating instrument that shows the vehicle wheels rotary motion trace.
Background technology
At present, the motor-driven vehicle going direction is controlled bearing circle by chaufeur and is operated, due to non-between the bearing circle of self-propelled vehicle and wheel, directly be connected, so the direction in motor-driven vehicle going is that rotation amplitude and the number of turns that relies on the driver to control bearing circle with driving experience determined.Self-propelled vehicle on spacious road surface, travel the other side to the dish control require not need very accurate, but when self-propelled vehicle, travel on narrow road surface or meeting or self-propelled vehicle while moving storehouse, the understanding that just need to be perfectly clear for bearing circle status and wheel present position.If the rotational angle of bearing circle slightly has deviation, namely can depart from conditional travel direction, gently vehicle body is impaired, heavy cause serious traffic accident, all can cause serious injury self-propelled vehicle and occupant.In addition, only control by rule of thumb bearing circle, often can when bearing circle is got to the end, still firmly spin, this can strengthen the wearing and tearing that cause the bearing circle parts undoubtedly.Thus, conceived a kind of vehicle directional navigating instrument in order to process the problems referred to above.
Summary of the invention
In order to overcome the problem that in prior art, motor vehicle steering wheel exists in controlling, provide a kind of vehicle directional navigating instrument that shows the vehicle wheels rotary motion trace.
The technical scheme that its technical matters that solves the utility model adopts is: a circular scale that has centre hole is arranged on center shaft in the mode that activity coordinates, on calibrated disc dorsal part one center shaft, with fixed form, one weight is installed, on the center shaft of the positive side of calibrated disc, is set gradually the fluted disc installed with fixed form, the counting fluted disc of installing with manner and the pointer that is arranged on the center axle head with fixed form.On the back side of calibrated disc, be fixedly installed a planet gear, on planetary wheel with manner install one can be respectively with center shaft on the stem gear of fluted disc and the engagement of counting fluted disc, be big gear wheel and the engagement of the fixed gear plate on center shaft, the miniature gears of stem gear and the engagement of the free gear on center shaft of stem gear.Described calibrated disc is embedded on the box bottom with fixed form, and the box bottom is furnished with a transparent box cover.
The beneficial effects of the utility model: the utility model is simple in structure, reasonable in design, easy for installation, shows accurately, is conducive to the clear misalignment angle of wheel in motor-driven vehicle going and the rotation number of turns of bearing circle grasped of driver, ensures the safety traffic of self-propelled vehicle.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. box bottoms in figure, 2. transparent box cover, 3. instrument assembly, 4. calibrated disc, 5. pointer, 6. center shaft, 7. weight, 8. fluted disc, 9. counting fluted disc, 10. planet wheel spindle, 11. connect gears, 12. miniature gearss, 13. big gear wheels.
The specific embodiment
In the drawings, the utility model is by box bottom 1, and transparent box cover 2 and the instrument assembly 3 of installing within it form.Instrument assembly 3 has the graduated circular scale 4 of a mark, the center of calibrated disc 4 has axis hole, calibrated disc 4 is arranged on center shaft 6 in the mode that activity coordinates by axis hole, on calibrated disc 4 dorsal part one center shafts 6, with fixed form, one weight 7 is installed, on the center shaft 6 of calibrated disc 4 positive sides, set gradually the fluted disc 8 of installing with fixed form, the counting fluted disc 9 of installing with manner and the pointer 5 that is arranged on the center axle head with fixed form.On the back side of calibrated disc 4, be fixedly installed a planet wheel spindle 10, on planet wheel spindle 10 with manner install one can be respectively with center shaft 6 on the stem gear 11 of fluted disc 8 and 9 engagements of counting fluted disc, i.e. activity count fluted disc 9 engagements on the big gear wheel 13 of stem gear 11 and center shaft 6.Described calibrated disc 4 is embedded on box bottom 1 with fixed form, and transparent box cover 2 is fastened on box bottom 1, but by the rotation data of the position of pointer 5 on calibrated disc 4 in transparent box cover 2 clear view boxes and counting fluted disc 9.In use and operational process, with adhesive means, be fixed on box bottom 1 of the present utility model on the bearing circle of inclination, be fixed on the identical gradient that the utlity model has on bearing circle, when self-propelled vehicle is in craspedodrome, with the coaxial pointer 5 of weight 7 under the effect of weight 7, pointer 5 overlaps with the mark of calibrated disc 4 centers, shows that the front-wheel of self-propelled vehicle is facing to dead ahead.When bearing circle direction rotation to the left and right, calibrated disc 4 is done synchronous the rotation with bearing circle, the weight 7 and the pointer 5 that are fixed on center shaft 6 keep motionless under weight 7 effects, scale mark on calibrated disc 4 has meaned the rotation direction of wheel, the angle of pointer 5 and scale mark shows the deflection angle of wheel, when calibrated disc 4 rotates, be fixed on fluted disc 8 on center shaft 6 relative to not rotating, 11 of stem gears on planet wheel spindle 10 are driven, now the miniature gears on stem gear 11 12 drives 9 rotations of counting fluted disc, but the rotation number of turns of counting fluted disc 9 display direction dishes.
Claims (1)
1. vehicle directional navigating instrument, it is characterized in that: a circular scale that has centre hole is arranged on center shaft in the mode that activity coordinates, on calibrated disc dorsal part one center shaft, with fixed form, one weight is installed, on the center shaft of the positive side of calibrated disc, is set gradually the fluted disc installed with fixed form, the counting fluted disc of installing with manner and the pointer that is arranged on the center axle head with fixed form; On the back side of calibrated disc, be fixedly installed a planet gear, on planetary wheel with manner install one can be respectively with center shaft on the stem gear of fluted disc and the engagement of counting fluted disc, be big gear wheel and the engagement of the fixed gear plate on center shaft of stem gear, the miniature gears of stem gear and the engagement of the free gear on center shaft; Described calibrated disc is embedded on the box bottom with fixed form, and the box bottom is furnished with a transparent box cover.
