The utility model discloses the steering wheel that turns to the angle and correspond that makes the car front wheel turns to number of turns surveyability on corresponding display device, and help is begun to learn the driver and just whether is being returned, is being mastered the steering wheel and turn to the number of turns, in time adjust the wheel angle falling drivings in -processs accuracy judgement wheels such as storehouse, side parkings, and simultaneously, this type display device simple structure, economical and practical, easily production are processed and the popularization.
Description
Technical field
The utility model belongs to detecting instrument technical field, and specifically, particularly a kind of vehicle front turns to read out instrument, turns to the number of turns for display automobile front-wheel steering angle and correspondence direction dish.
Background technology
Along with the raising of expanding economy and people's living standard, the quantity of automobile also gets more and more, and the people of driving also gets more and more.For present automobile, due to blocking of sight line, steerman cannot see turning to of front left and right wheels intuitively in car, and for beginner, unskilled owing to operating, usually cannot judge oneself beat the degree in direction and the degree of wheel steering because of nervous at heart, cause puzzlement.
For this problem, people have set about research, if application number is the Chinese patent of 200920112564.9, propose a kind of automobile steering rudder position intelligent display device, the angle of rotating shaft is obtained by angular-motion transducer, carry out signal conversion by Intelligent conversion circuit, realize the position intelligent display of motor turning rudder.And for example application number is the Chinese patent of 201120111930.6, proposes a kind of automobile tire position and steering wheel turn number display device, by configuring corresponding gear and coder turning on main shaft, and then realizes the display of automobile tire position and steering wheel turn number.
But above-mentioned solution is Shortcomings part still: more complicated in structure on the one hand, the structure both having related to machinery also relates to electrical structure, adds cost of manufacture, and on the other hand, the installation of relevant device, debugging, maintenance cost increase.
Summary of the invention
The purpose of this utility model be devise a kind of structure simple, economical and practical, be easy to production and processing and popularization, simultaneously a kind of vehicle front of the steering angle of vehicle front and clear, the accurate display of the wheel steering number of turns can be turned to read out instrument again.
For achieving the above object, the utility model adopts following scheme.
A kind of vehicle front turns to read out instrument, it is characterized in that, comprises connecting rod and display circuit; Described display circuit comprises slide rheostat, protective resistance, DC ammeter, switch; Described connecting rod is connected with the track arm of the slide plate of described slide rheostat and described vehicle front, steering shaft respectively; Described slide rheostat, described protective resistance, described DC ammeter, described switch are connected successively by wire.
Described slide rheostat is the arc sliding rheostat of resistance nonlinearities change, described connecting rod drives the rheostatic slide plate of described arc sliding to slide, and the rheostatic slide plate of described arc sliding is identical relative to the size of the size of the deflection angle of described slide plate initial position, direction and the steering angle of described vehicle front, direction in sliding process; The rheostatic slide plate of described arc sliding is also identical relative to the size of the deflection angle of described pointer initial position, direction with DC current list index in described display circuit relative to the size of the deflection angle of described slide plate initial position, direction in sliding process.
Described DC ammeter dial plate high scale and comment represent the wheel steering number of turns of automobile front wheel steering angle and correspondence respectively.
The described wheel steering number of turns converts in advance according to the relation of described vehicle front actual steering angle and the wheel steering number of turns.
Described display circuit is powered by Vehicular accumulator cell.
By above technical scheme, the utility model has following advantage compared to existing technology: the utility model makes the wheel steering number of turns of the steering angle of vehicle front and correspondence very clear on corresponding read out instrument, helps to begin to learn chaufeur and is falling in the driving procedure such as storehouse, side parking accurately to judge whether wheel is just returning, grasp the wheel steering number of turns, adjust wheel angle in time.Meanwhile, this type display device structure simple, economical and practical, be easy to production and processing and popularization.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model vehicle front turns to read out instrument.
Fig. 2 is display circuit schematic diagram of the present utility model.
Fig. 3 is display interface schematic diagram of the present utility model.
Detailed description of the invention
The utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, a kind of vehicle front turns to read out instrument, comprises connecting rod 2 and display circuit; Described display circuit comprises slide rheostat 1, protective resistance R, DC ammeter 9, K switch 1; Described connecting rod 2 is connected with the track arm 3 of the slide plate of described slide rheostat 1 and described vehicle front 4, steering shaft 7 respectively; Described slide rheostat 1, described protective resistance R, described DC ammeter 9, described K switch 1 are connected successively by wire.
Before driving, first open the K switch 1 of display circuit.
In driving procedure; when steering wheel return timing; the slide plate of slide rheostat 1 is positioned at its stroke meta; now; by the arc sliding rheostat of pre-configured protective resistance R and resistance nonlinearities change; ammeter pointer in display circuit points to amperemeter/ammtr range meta, and corresponding amperemeter/ammtr dial plate high scale and comment represent that the wheel steering number of turns of now automobile front wheel steering angle and correspondence is 0.
When beating direction left, bearing circle 8 in nose wheel steering, by steering shaft 7, deflector 6, track arm 3, tierod 5 driving automobile front-wheel 4 is to anticlockwise, simultaneously, track arm 3 drivening rod 2 moves, connecting rod 2 drives the slide plate deflection angle α left of slide rheostat 1, now, resistance in slide rheostat 1 incircuit becomes large, in circuit, electric current reduces, DC ammeter 9 pointer deflects α left, show now vehicle front left-handed turning to angle [alpha], simultaneously by conversion in advance, also can know and know that now bearing circle left-handed turning is to the number of turns.
When beating direction to the right, its principle is as implied above.
Foregoing description only proposes as the technical scheme of the utility model embodiment; not as the single limiting condition to its technical scheme itself; all do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
