Description

Technical Field

[0001] The utility model relates to the technical field of wheel speed sensors, and particularly relates to a wheel speed sensor with a heat insulation cover. Background Technique

[0002] A wheel speed sensor is a sensor used to measure the wheel speed of an automobile. Commonly used wheel speed sensors mainly include: magnetoelectric wheel speed sensors and Hall wheel speed sensors.

[0003] In the prior art, a Chinese patent document with the authorization announcement number CN214794855U discloses a wheel speed sensor with a heat insulation cover on the sensing head. By sleeving a heat insulation cover on the wheel speed sensor, this wheel speed sensor can effectively solve the problem of high-temperature oxidation of the iron core of the magnetoelectric wheel speed sensor, and at the same time can protect the sensor head, avoiding the problem that the sensor function fails or the sensor melts due to the rapid increase in the ambient temperature around the sensor exceeding the temperature resistance level of the chip during the emergency and frequent braking process of the vehicle, improving the overall safety of the vehicle and eliminating potential accident risks.

[0004] However, when the above solution is used, the opening of the U-shaped heat insulation cover is set away from the threaded mounting hole direction, while the threaded mounting hole is usually set between the sensor and the wheel when the wheel speed sensor is installed. Therefore, there will be wind passing through the inner side of the heat insulation cover in the direction of the opening of the U-shaped heat insulation cover, and the U-shaped structure cannot effectively guide the wind. When the vehicle is moving at a relatively high speed, it will cause a large wind resistance on the U-shaped heat insulation cover, resulting in the risk of bending and falling off of the heat insulation cover.
