Description

Technical Field

[0001] The utility model relates to the technical field of ABS sensors, in particular to a high-performance ABS sensor with a snap-fit ​​installation structure. Background Art

[0002] ABS sensor is used in ABS (anti-lock braking system) of motor vehicles. In ABS system, inductive sensor is mostly used to monitor vehicle speed. ABS sensor outputs a set of quasi-sinusoidal AC signals through the action of the gear ring that rotates synchronously with the wheel. Its frequency and amplitude are related to the wheel speed. The output signal is transmitted to the ABS electronic control unit (ECU) to realize real-time monitoring of wheel speed.

[0003] However, when installing a high-performance ABS sensor, the ABS sensor is stably fixed on the vehicle by connecting the assembled bracket with bolts and the vehicle thread groove. Such an installation structure requires removing the bolts before removing the wheel speed sensor, which results in turning the bolts each time the sensor is removed, which is cumbersome and the sensor is easily damaged when exposed to the external environment. Therefore, a high-performance ABS sensor with a snap-on installation structure is designed in this case. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1.
