Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically a high-temperature resistant ABS wheel speed sensor. Background Technology

[0002] Wheel speed sensors are used to measure the rotational speed of a car's wheels. Commonly used wheel speed sensors include magnetoelectric wheel speed sensors and Hall effect wheel speed sensors. Wheel speed information is essential for modern cars, as it is required by vehicle dynamic control systems, electronic stability programs, anti-lock braking systems, and automatic transmission control systems. Therefore, wheel speed sensors are one of the most critical sensors in modern cars. Due to high external temperatures and prolonged wheel operation, dust easily adheres to the surface of the detection probe, affecting heat dissipation. This causes the ABS wheel speed sensor to overheat, resulting in low detection accuracy and a short lifespan, necessitating frequent replacement. Utility Model Content

[0003] The purpose of this invention is to provide a high-temperature resistant ABS wheel speed sensor to solve the problem mentioned in the background art that, due to the high external temperature and the long-term operation of the wheel, dust easily adheres to the surface of the detection probe, affecting heat dissipation, causing the ABS wheel speed sensor to overheat, resulting in low detection accuracy, short service life, and frequent replacement.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant ABS wheel speed sensor, comprising a sensor housing, a heat dissipation assembly, and a mounting assembly;

[0005] Wherein: a detection probe is installed inside the sensor housing, and a terminal is connected to the tail of the sensor housing;

[0006] The heat dissipation assembly includes a mounting sleeve fitted onto the surface of the detection probe. The surface of the mounting sleeve is provided with heat dissipation holes. A mounting ring is installed on the inner wall of one end of the mounting sleeve. A non-powered fan is rotatably mounted on the surface of the mounting ring.

[0007] The mounting assembly includes a mounting bracket located at the bottom of the sensor housing, a mounting buckle at the top of the mounting bracket, and semi-annular mounting holes corresponding to the surfaces of the mounting bracket and the mounting buckle. The sensor housing is inserted into the middle of the mounting holes, and mounting screws are provided on both sides of the mounting buckle. The mounting screws are threaded onto the top two sides of the mounting bracket.

[0008] As a preferred embodiment of this utility model: one end of the sensor housing is provided with an annular groove, and the inner wall of the other end of the mounting sleeve is provided with a fixing ring, which is inserted through the inner wall of the annular groove.

[0009] As a preferred embodiment of this utility model: a filter screen is installed on the inner wall of the mounting sleeve, and the filter screen corresponds to the heat dissipation holes.

The surface of the mounting sleeve 41 is surrounded by heat dissipation holes 42. A mounting ring 43 is installed on the inner wall of one end of the mounting sleeve 41. A non-powered fan 44 is rotatably mounted on the surface of the mounting ring 43.

[0032] In practical use: A mounting sleeve 41 is fitted onto the surface of the detection probe 2. The mounting sleeve 41 serves a protective function, preventing dust from adhering to the surface of the detection probe 2. Heat dissipation holes 42 are opened around the surface of the mounting sleeve 41. A non-powered fan 44 is rotatably mounted on the inner wall of one end of the mounting sleeve 41 through a mounting ring 43. When the vehicle is in motion, the airflow flows quickly through the mounting sleeve 41, causing the non-powered fan 44 to rotate. The rotation of the non-powered fan 44 causes the airflow to carry away the heat generated by the detection probe 2, ensuring that the detection probe 2 can work continuously in high-temperature environments.

[0033] Please see Figure 1 , Figure 3The mounting assembly 5 includes a mounting bracket 51 located at the bottom of the sensor housing 1. The top of the mounting bracket 51 is provided with a mounting buckle 52.

[0035] Please see Figure 4 One end of the sensor housing 1 has an annular groove 6, and the other end of the mounting sleeve 41 has a retaining ring 7 installed on its inner wall. The retaining ring 7 is inserted through the inner wall of the annular groove 6.

[0036] In practical use: one end of the sensor housing 1 has an annular groove 6, and the inner wall of the other end of the mounting sleeve 41 is fitted with a retaining ring 7.

[0037] Please see Figure 2 The inner wall of the mounting sleeve 41 is fitted with a filter screen 8, which corresponds to the heat dissipation hole 42.

[0038] In practical use: The inner wall of the mounting sleeve 41 is equipped with a filter screen 8. When the airflow enters the interior of the mounting sleeve 41 through the heat dissipation hole 42, it passes through the filter screen 8 to filter out dust particles, thus preventing dust particles from entering the interior of the mounting sleeve 41 and affecting the normal operation of the detection probe 2.

[0043] Please see Figure 2 , Figure 4The installation sleeve 41 is a copper sleeve.

[0044] In practical use: The mounting sleeve 41 is made of copper, which gives it a good heat dissipation effect.

[0045] A mounting sleeve 41 is fitted onto the surface of the detection probe 2. The mounting sleeve 41 serves a protective function, preventing dust from adhering to the surface of the detection probe 2. Heat dissipation holes 42 are formed around the surface of the mounting sleeve 41. A non-powered fan 44 is rotatably mounted on the inner wall of one end of the mounting sleeve 41 via a mounting ring 43. When the vehicle is in motion, the airflow flows rapidly through the mounting sleeve 41, causing the non-powered fan 44 to rotate. The rotation of the non-powered fan 44 causes the airflow to carry away the heat generated by the detection probe 2, ensuring that the detection probe 2 can continue to work in a high-temperature environment.
