Description

  The present invention relates to a mileage and braking response device applied to various types of tires.

  Known mileage meters can be broadly divided into two types, one is a mechanical odometer and the other is an electronic odometer. The mechanical mileage meter is provided on the front wheel shaft side, and the gear set that receives the front wheel drive transmits the rotation state of the front wheel rotation to the mileage meter with a wire to indicate the mileage. The electronic odometer uses an electronic device as a sensing device, and the data of the electronic mileage is also converted into a signal by the sensing device, and further transmitted to the electronic odometer circuit via a signal line. The signal is converted into mileage data by a program written in advance, thus achieving the purpose of mileage display. Both mechanical odometers and electronic odometers are equipped with a gear set or program that fits the tires of a given standard before shipping, so that when a user replaces a tire with a different standard. The mileage displayed by the mileage meter may cause an error due to a difference in tire standards, which may result in a situation that does not match the actual mileage, which may cause traffic rules violations or dangers.

Among them, a design of a kind of electronic odometer is described in Patent Document 1, and as shown in FIGS. 4 and 5, it is provided with a plurality of drive pieces 52 on the inner periphery of the side hole 51 of the hub 5. Further, an inner shaft sleeve 62 through which the shaft rod 622 is passed is assembled in the case sheet 6, the magnet rotor 7 is fitted to the outer periphery 621 of the inner shaft sleeve 62, and a plurality of the above-described drives are provided at the outer end of the magnet rotor 7. Convex ear pieces 71 combined with the notches 521 between the pieces 52 are provided, and the circuit board 8 including the sensor 81 is inserted into the insertion portion 61 on one side of the case sheet 6 on one side of the front fork 63. During driving of the vehicle, the driving piece 52 in the hub 5 drives and rotates the magnet rotor 7, and the design of the electronic mileage meter is achieved by the detection of the sensor 81. However, this design has the following disadvantages.
1. The magnet rotor 7 is directly fitted on the outer periphery 621 of the center shaft sleeve 62, and when the magnet rotor 7 is driven to rotate at a high speed, the inner hole 72 generates friction with the outer periphery 621 of the center shaft sleeve 62. Wears out in a short time and breaks down.
2. The magnet rotor 7 is directly fitted on the outer periphery 621 of the central shaft sleeve 62, and the gap size between them must be a reasonable size, which greatly increases the accuracy requirements during processing, and thus increases the manufacturing cost. And the number of defective products also increases.
3. In order to minimize the friction state between the magnet rotor 7 and the middle shaft sleeve 62, a gap is reserved between the inner hole 72 and the outer periphery 621 of the middle shaft sleeve 62. For this reason, when the magnet rotor 7 is driven to generate high-speed rotation. Magnetic poles measured when it becomes impossible to maintain a smooth and stable rotation, cause wobble and instability, and when relatively high accuracy travel distance data is required and the magnet rotor 7 is further divided into a large number of magnetic poles. Data accuracy is greatly reduced.
4). After the notch 521 between the convex ear piece 71 and the drive piece 52 of the magnet rotor 7 is combined, a gap 522 is generated between both sides of the convex ear piece 71 and the notch 521, and the magnet rotor 7 is moved to the magnet rotor 7 when the vehicle advances or stops. A drive delay or stop situation is generated, which causes inaccurate braking problems in the mileage data and ABS braking system (see FIG. 6).
