Abstract
The utility model relates to an indicator for changing machine oil, which divides a driving device into a last stage component and a next stage component and keeps the state error on the downstream of the last stage component. The next stage component is separated from the last stage component on transmission when the next stage component returns to zero. The next stage component and an indicator wheel reduce the contingent state error to the great extent when both return to zero simultaneously. Especially the last stage component is provided with a gearwheel with a plurality of continuous gears, the state error is apportioned by the gears of the last stage component. In addition, the initial input error is reduced because of actuating of a rotor wheel body with ten kilometers of a distance recorder. Therefore, the accuracy of the engine oil remindful indicator is enhanced greatly. The structure of a driven speed reducing apparatus is simplified efficiently. The utility model not only reduces the manufacturing cost, but also improves volumetric efficiency simultaneously, and solves the present multinomial puzzles efficiently.
Description
Technical field
The utility model is about a kind of oil exchange indicator, especially a kind of oil exchange indicator that independently makes zero.
Background technology
For reminding the motorcycle driver behind certain mileage that travels, change engine oil more in good time, the part motorcycle is at the other oil exchange alarm set that is provided with the mileometer interlock of mileometer.Formerly in the technology, as shown in Figures 1 and 2, because mileometer 6 is by for example six turn wheel bodys 61,62,63,64 ... coaxial transversely arranged, and by mechanical drive from front-wheel, drive wheel body 61 (unit is 1/10th kilometers) rotation of the rightmost side, left side at rightmost side wheel body 61, the single transmission body of rod is then arranged, when treating that wheel body 61 rotates a circle, drive the adjacent wheel body 62 in its left side (unit is kilometer) and rotate 1/10th circles, owing to all post 0 to 9 figure denote on each wheel body, this drives the carry action that promptly means on the mileometer.In like manner, kilometer wheel body 62 rotates and will drive ten kilometers wheel body 63 carries a week, and hundred kilometers, thousand kilometers and ten thousand kilometers the rest may be inferred.
Because general motorcycle whenever travels 1,000 or 2,000 kilometer need are change engine oil more, therefore, one traditional oil exchange alarm set can be accepted drive from 600 kilometers wheel bodys 64 of mileometer with a gearing 7, drives to have indicator wheel 8 and thousand kilometers wheel bodys that color for example indicates and carry out similar rotation.And after more change engine oil finishes, by the manually operated clearing device 9 of user, push the rod member 91 that makes zero that is formed with a depression cam surface, and drive the gear 92 that makes zero of the depression cam surface driving of this rod member that makes zero, and drive indicator wheel 8 and make zero, allow alarm set start at again.
As shown in Figures 3 and 4, gearing 7 is to comprise that a left side has external tooth, the right side has the intermittently intermittent gear 71 of internal tooth 710; One is arranged on intermittent gear 71 inner right side, and the left side has internal tooth 710 three teeth at intermittence that are connected intermittent gear 71, and the right side is the mesomerism gear 72 of six teeth; Reach a left side and have the internal tooth that is connected mesomerism gear 72 right sides six teeth, the clutch gear 73 of the built-in clutch part 730 in right side, and with clutch gear 73 linking indicator wheels 8.
Because clutch gear 73 can drive indicator wheel 8 and rotate, but when indicator wheel 8 active rotation, 73 of clutch gears are not rotated by reverse guiding thereupon.That is the gear that makes zero only can drive indicator wheel 8 and reply the position of making zero, and shows no sign of for the gearing 7 in indicator wheel 8 upstreams to exert an influence.In other words, gearing 7 is to be broken away from by clutch gear 73, is not subjected to the reverse transmission of indicator wheel 8, remains on the position before making zero fully, not influenced by flyback action.
Because of rotating a circle, intermittent gear 71 represents motorcycle driving 1,000 kilometer, and four internal tooth 710 each intervals 90 degree intermittently as shown in Figure 4, that is in two space width corresponding to car about 250 kilometers distances of travelling, when certain person be has just driven mesomerism gear 72, clutch gear 73 at intermittent gear 71, reach indicator wheel 8 and rotate after change engine oil and making zero more, then intermittently internal tooth 710 be the position in position at intermittence as shown in Figure 5, motorcycle nearly will travel that 250 kilometers left side three tooth spirals that just can drive mesomerism gear 72 once more change again.
Otherwise as shown in Figure 6, if certain second is change engine oil more when intermittent gear 71 turns to the standby position that soon drives mesomerism gear 72 once more, though then certain second makes zero indicator wheel 8, but because of gearing 7 is maintained at the preceding state of changing oil, motorcycle just starts to travel, the internal tooth 710 of intermittent gear 71 will be changeed by left side three tooth spirals that standby position directly drive mesomerism gear 72, that is the oil exchange alarm set is by baffled " pouring water " more than 200 kilometers.More the change engine oil number of times is more than enough to suppose each driver, and " state reservation " error of this kind gearing 7 causes the driver at least on average to be poured water about 125 kilometers undoubtedly.
In addition, even ignore error problem from the distance measuring of front-wheel, single hundred kilometers wheel bodys, 64 errors with mileometer own can reach tens of kilometers, are called the error originated from input of oil exchange alarm set at this.So the deviation accumulation under exaggeration situation will make motorcycle behind change engine oil more, even only travel kilometer surplus in the of 600 and less than 700 kilometers, indicator wheel 8 just presents reminds change engine oil to indicate.So, not only can not reach correct prompting driver's effect, increase on foot on the contrary and drive puzzlement.
Moreover, intermittent gear 71 must be made especially with clutch gear 73, and mesomerism gear 72 will be placed in intermittent gear 71 and clutch gear 73 inner spaces, and with the correct interlock of the internal tooth of intermittent gear 71, manufacturing cost or assembly cost all thereby improve, and complex structure also makes packaging efficiency descend; The space of one improvement is provided undoubtedly.
