Description of the new type: [Technical field to which the new type belongs] This creation is related to the rotational speed sensing device, especially _ a kind of rotational speed reduction device applied to the vehicle. The speed of the vehicle is obtained through the measurement of the rotational speed. ],. Conventional locomotive speed sensing devices, as shown in Figure 丨, are mostly set on (not shown in the figure)-a shaft hole 32 is set on the output shaft 34, and the second 34 and a shaft 30 fit together, so the current wheel rotates At the same time, when the rotating shaft 30 is rotated ^ = and the end of the rotating shaft 30 is more fixed-E4 and rotates with the rotating shaft 30-the steel cable 4 is sheathed with a sheath 40 to protect the steel cable 4 from being worn. The steel face is connected to the y-speed wire 9 and the movement of the E-4 is converted to the lying of the pointer through the speedometer 9 _ structure. Its practice is well-known and will not be described in detail here. In addition, the rotating shaft 30 is pivotally set in a base 1 and then fixed on the output shaft seat 22 in a worm manner through a fixing element, and the output shaft seat 22 is fixed to the front wheel axle frame of the locomotive (fig. Undisclosed). ^ However, this traditional structure also has its shortcomings. One of them is the lack of sensitivity. When the front wheel of the car rotates at a low speed, the hand of the speedometer 9 swings very little, or there is no change. Another disadvantage is that the pointer changes immediately when the speed changes sharply. One of the reasons is caused by the inertia of the mechanical structure itself, and the characteristics of the material of the mechanical structure such as elasticity or rigidity. In addition, there are other problems in the mechanical structure, such as wear and fatigue. ^ Furthermore, if the steel cable 4 is broken due to an accident, it will be difficult to repair it by hand, and it will be sent to a repair shop for replacement. In addition, the most important point is that the traditional mechanical transmission of the front wheel rotation mechanism shown in Figure 丨 is combined with the electronic electronic county board, because the electronic wire board is to simplify the structure and emphasize the convenience of maintenance and replacement. One of the characteristics is that each electronic sensor H sends signals back to the dashboard in an electrically connected manner.

In addition to the conventional technology of Tian 2, Chinese Patent Bulletin No. 495051 also discloses I, an electronic wire for measuring the speed of wheels. At first glance, this type of device is fighting, and the fundamental problem is that if you want to use this kind of The device needs to be reset 1 ^ 0 '. Once the axle 220 is changed, the rim (not labeled in the figure) also needs to be changed. Also = wish, if you want to fully use the device of level 2, the traditional mechanical transmission ¥ Due to the structural inability to make the device of 2 closed, some of the components in the figure such as the shaft hole 32 and the output shaft 34 are used in accordance with the law, which is a significant loss and very uneconomical. From this, it can be seen that there is an urgent need for a new type of electronic speed sensor that can be applied to the existing connection of the wheel soil in the conventional mechanical transmission method in the connection relationship of the structure.
