Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an ABS sensor assembly. Background Art

[0002] The ABS sensor assembly includes a wheel speed sensor and an electronic control unit (ECU). The wheel speed sensor is responsible for detecting the speed of the wheel and converting this information into an electrical signal and sending it to the ECU. The ECU will calculate the circumferential deceleration and slip rate of the wheel based on the received signal. When it detects that the wheel has a tendency to lock, the ECU will instruct the brake pressure regulator to adjust the braking force accordingly to prevent the wheel from locking. Vehicles equipped with the ABS system can prevent the wheel from locking during emergency braking, thereby maintaining the vehicle's controllability and directional stability, avoiding side slip and deviation, and greatly improving driving safety.

[0003] The publication number is: CN210363774U. An ABS wheel speed sensor assembly is disclosed, including a sensor head, a multi-core wire, a sheath, a plug, a terminal, a bushing, a plastic seal, a fixed disk, a sleeve, a plug-in portion, a heat dissipation hole, a heat pipe, a micro heat sink, a dustproof net and a sealing ring. The sensor head is provided with a fixed disk, a bushing is installed at one end of the fixed disk, and a sleeve is installed at the other end of the fixed disk. Heat dissipation holes are evenly opened on one side of the sensor head, a heat pipe is installed in the heat dissipation hole, and one end of the heat pipe is connected to the outside world. Micro heat sinks are provided on the top and bottom of the inner wall of the heat pipe, and a dustproof net is installed on one side of the micro heat sink. One end of the sensor head is connected to the multi-core wire through the plug-in portion, and the structure is simple.

[0004] The ABS sensor does not have its internal sensor chip reinforced. The shaking and bumps generated during driving can easily cause the sensor chip to loosen. Since the control of the ABS system relies on the signal of the wheel speed sensor, a loose sensor assembly chip may cause the collected wheel speed signal to be sometimes good and sometimes bad, or to have no signal at all or to have spike interference. This will cause the ECU to misjudge and think that the wheel is tending to lock. It may take unnecessary decompression adjustments, causing the vehicle to deviate or snake, resulting in a traffic accident. Therefore, there is still room for improvement in this technology.
