Description

Technical Field

[0001] The utility model relates to the technical field of sensor equipment, in particular to an ABS wheel speed sensor with high anti-interference. Background Art

[0002] Wheel speed sensor is a sensor used to measure the rotation speed of the car wheels. For modern cars, wheel speed information is essential. Vehicle dynamic control system (VDC), electronic stability program (ESP), anti-lock braking system (ABS), automatic transmission control system, etc. all need wheel speed information. Therefore, wheel speed sensor is one of the most critical sensors in modern cars.

[0003] The application number is CN202021079936.5, which discloses an ABS wheel speed sensor, belonging to the field of sensor devices, including an electric wire, a hook is clamped on the outer side of the middle part of the electric wire, a hook groove is arranged inside the hook, a fixing seat is fixedly welded on the upper end of the hook, a screw is fixedly welded on the upper end of the fixing seat, the screw is connected to the vehicle body through a thread, a plug is fixedly welded on the left end of the electric wire, and a rubber sleeve is fixedly welded on the right end of the electric wire. The ABS wheel speed sensor connects the screw to the vehicle body through a thread, which is convenient for clamping the electric wire into the hook groove, and is convenient for quickly installing the electric wire. The design of the fixing seat can prevent water stains from penetrating into the outer surface of the screw and corroding, causing corrosion and damage to the screw and the screw hole, making it difficult to remove the screw; the connection between the electric wire and the support block is fixedly welded with a rubber sleeve, which can prevent the rubber layer of the electric wire from breaking and detaching from the support block, thereby improving the service life of the ABS wheel speed sensor, and the design of the buffer groove can increase the flexibility of the rubber sleeve, so that it can buffer the electric wire inside the rubber sleeve when it is subjected to force, thereby preventing damage to the electric wire.

[0004] An ABS wheel speed sensor disclosed in the above document has the following defects: when the sensor is in use and needs to detect the rotation speed of the wheel hub, the orientation of the wheel hub will be different when the wheel is turning. The sensor needs to adjust the position of the detection head to align with the wheel hub to improve the recognition efficiency during turning. The structure does not have a corresponding sensor fixed, and a corresponding adjustment structure needs to be set to cooperate with the sensor to identify the wheel rotation speed.

[0005] It can be seen from this that the existing ABS wheel speed sensor does not have the function of adjusting the position to detect the wheel speed. It is necessary to improve the existing deficiencies and provide a function that can detect the wheel speed. Utility Model Content
