Abstract
Description
Technical Field
[0001] The utility model relates to the field of wheel speed collection, in particular to a wheel speed collector. Background Art
[0002] The wheel speed collector is a device that uses the principle of magnetoelectric effect to measure the wheel speed. It determines the wheel speed through the pulse signal received by the induction coil and judges the vehicle's motion state based on this information. In existing wheel speed collectors, the magnets are generally fixed on the spokes. If the number of magnets is small, there will be problems such as low trigger frequency and low sensitivity. In addition, the spokes are relatively smooth. Under the influence of the external environment, the magnets often deviate and fall off, which easily generates erroneous signals and has low accuracy. Utility Model Content
[0003] In view of the defects of the existing wheel speed collector, the technical problem to be solved by the utility model is to provide a wheel speed collector that is stable, not easy to deviate and fall off, has high accuracy and high sensitivity.
[0004] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, the utility model is realized through the following technical measures: a wheel speed collector, including a sensor, a magnet, and a locking plate, the sensor is fixed on the inner side of the rear hook, the locking plate is a locking plate of the hook lock, the locking plate is connected to the rear hub, and the magnet is fixed on the locking plate.
[0005] Furthermore, the lock plate is provided with a plurality of lock openings, and a magnet mounting hole is provided between each of the lock openings, and the magnet is fixed in the magnet mounting hole.
[0006] Furthermore, a through hole is provided at the center of the magnet, and the magnet is fixed in the magnet mounting hole by a fixing bolt.
[0007] Furthermore, the magnet is fixed in the magnet mounting hole by adhesive.
[0008] Compared with the prior art, the advantages of the utility model are: in this wheel speed collector, the sensor is fixed on the inner side of the rear hook claw, which is hidden and stable and not easy to fall off; the magnet is fixed on the lock plate, which is not easy to deviate or fall off, thereby improving the speed measurement accuracy; there are many magnets, the trigger frequency is high, and the sensitivity is high.
