New description: [New technical field] This is the structure of the locomotive speedometer, especially the speedometer structure that uses the sensor to measure the number of gaps through which the driven tooth sensing part rotates. [Prior Art] According to the conventional locomotive speed governor structure, please refer to _-Qing, which is mainly for the front part 12 of the locomotive front wheel than the middle shaft pipe 11, and is provided with a group driving ear i 3 at the end portion 12 'Another combination—a gear cover 2 that is positioned in front of the locomotive and does not rotate with the hub i. In the tooth=cover 2, a driven gear 2 i is disposed on the periphery of one end of the driven gear 2 : The ploughing area 2 1 1 has the inner hole peripheral edge of the thorn set - the inner cut surface 2:1 drive _2 3 'the inner cut surface 2 3 1 and the set of outer cut surface of the driven gear 21 211 is matched with the outer edge of the driving ring member 2, and a set of lug pieces 2 3 2 is formed. On one side of the gear cover 2, a rotation speed output gear 2 is provided and the rotation speed is set. The output gear 2 2 is perpendicular to the driven gear 2 L. L: When the locomotive is driven to rotate the shaft tube 11 in the front wheel to drive the hub 1, the set driving deaf 3 provided at the end portion 12 of the center shaft tube 11 is driven. The lug piece 2 of the peripheral edge of the driving ring member 2 rotates the driving & member 23, and simultaneously drives the driven gear 21 to rotate, and drives the u-drive & The gear 2 2 group-body transmission cable 2 4 drives the vehicle speed 11 and achieves the purpose of mileage, but the conventional structure has the following disadvantages: 1. The design is limited to the general mechanical speedometer, and Mechanical car-like electronic speedometers are easily damaged. 2 After the components are rotated at high speed for a period of time, the M328559 of foreign objects or dirt, moisture, etc. often infiltrates or causes gears to malfunction, and there are many parts, which is time-consuming and labor-intensive for maintenance. It must be repaired from time to time and the speed of the vehicle is 3, and the speed of the pointer is high, and the tolerance is large, and the correct speed cannot be clearly indicated, and the speeding problem occurs. There are appraisers <_ she, turn (10) axis m to provide - fresh material, Lai Rong New sneaked parts manufacturers to wait for Lai. Early ^ κ is the target locomotive [New content] ~ The problem to be solved by this creation is to overcome the deficiencies of the conventional locomotive speed reducer, which is easy to damage, difficult to maintain and has large tolerances. To this end, the technical core of the paste system is to provide a structure of the locomotive speed governor, mainly in the hood's setting - the crane piece and the sense wire, the follower is provided with a sensing part, and the sensing part is set Wei A number of thin, mechanical wire has a "sensing zone, the domain should be able to side the passer _ through the number of defects, and by logical operation to obtain the mileage of the domain car and transmitted by the signal line to the speed indicator on the speedometer In this way, the parts of the speed governor can be simplified and the purpose of simple maintenance can be achieved, and the number of the gaps through which the driven tooth sensing portion rotates can be avoided by the field device to avoid the tolerance to achieve the effect of improving the speed correct rate. [Embodiment] In order to make it easier for your examiner to understand the structure of the creation and the effect it can achieve, please refer to the following description: First, please refer to Figure 2, the locomotive speed structure of this creation, Mainly attached to the end portion 3 2 of the shaft tube 3 1 in the front wheel hub 3 of the locomotive, a set of protrusions 33 are provided, and at the end portion 32 of the M328559, a cover which is located not to rotate with the hub 3 of the locomotive front fork is additionally assembled. 4, in the cover 4, a set of follower members 4 is provided, and the follower member 4 is provided with a sensing portion 4, and a plurality of annular gaps are formed around the sensing portion 411. The notch 411 can be in the shape of a tooth or a hole (as shown in FIG. 3). The cover 4 is provided with a fixing seat 42. The fixing seat 42 is available for sensing - the H4 3 is installed by the opening 4 21 . a person, and the surface of the follower 41 / is provided with a groove 4 丄 3 corresponding to the protrusion 3 3 , wherein the sensor 4 3 has a sensing area 4 3 1 'the sensing area 4 3 ! a transmitter and a receiver, wherein the sensing portion 411 of the follower 41 is located in the sensing area 43 3 , and the sensor 4 3 is connected to the signal wire 4 4 , and the signal line 4 4 is connected to A schedule (not shown). The creation is in the actual _, the time is referred to the fourth and fifth, when the locomotive travels to rotate the shaft tube 31 of the front wheel to drive the hub 3, the protrusion 3 3 provided at the working end portion 3 of the central shaft tube 3 is correspondingly embedded. In the recess 4 丨 3 of the follower 4 1 , the driven part 4 can be driven to rotate the sensing portion 41 从 on the follower 41, and since the sensing portion 4 is provided with a gap 412, When the follower 41 rotates, the sensing portion 411 has a effect on the emission II and the connection (4) on the sensor 43, and the notch 4丨2 allows the receiver to receive the signal from the transmitter, whereby The sensing area 43 I can detect the number of gaps of the driven member 4 sensing portion 411 through the gap 4, and calculate the mileage of the locomotive by logic operation and transmit the signal to the vehicle through the signal line. It can be used for the driver to know the mileage of the vehicle. In the implementation of the 7F, the transmitter and the receiver can also be placed on the same side of the _ 4 3, when the follower 4 i rotates, the signal of _ will be transmitted to the slave M328559 When the signal is transmitted through the gap 412 and then bounced back, the signal is received by the receiver, thereby achieving the purpose of knowing the mileage of the vehicle. The effect of the present invention is that, by means of the cover 4, a follower 4 and a sensor 4 3 are provided, and the sensor 4 has a sensing area 4 31, and the sensing area 4 31 can detect the slave. The sensing unit 41 1 rotates through the number of π 412, and by means of logic, it is known that the locomotive has reached the mileage and the speed is transmitted from the speed to the red speed indicating the speed, which not only simplifies the speed of the vehicle, but also reaches (4) For the purpose of maintenance, the sensor 43 detects the follower 4 1 and the sensing portion 4 1 1 rotates through the π 4 丨 2 number of shots to avoid the tolerance to improve the speed of the vehicle. In summary, this creation can be used for fine-grained purposes and is not seen in the market, thanks to the purpose and effect of the above-mentioned locomotive speedometer.
