Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a wheel speed sensor with an adaptively adjustable length. Background Art

[0002] A wheel speed sensor is a sensor used to measure the rotational speed of a wheel. It usually consists of a magnet and an electromagnetic sensor, and is installed where the wheel rotates. It can detect the rotational speed and direction of the wheel in real time and transmit the information to the vehicle computer system for data processing and analysis. Since the wheel speed sensor is used to measure the rotational speed of the vehicle wheels, it is one of the most critical sensors in modern vehicles.

[0003] Chinese Patent Publication No. CN218824345U discloses a wheel speed sensor with an adaptively adjustable length, including: a wheel speed sensor probe, the upper part of the wheel speed sensor probe is fixedly connected with a wheel speed sensor wire harness, and a spiral wheel speed sensor wire harness is arranged in the middle of the wheel speed sensor wire harness; a first rubber sleeve is sleeved on the wheel speed sensor wire harness, and the first rubber sleeve is connected with the wheel speed sensor wire harness by glue. By optimizing the design, the wheel speed sensor wire harness with an originally unchangeable length is designed into a spiral shape, which can better adapt to the length change caused by the wheel jump compared with the previous wheel speed sensor wire harness, enabling a common sensor to be used for different models on the same platform. It can not only reduce the layout space and the interference risk with surrounding parts, but also reduce the layout space through multiple rubber sleeves and fixed buckles, and at the same time design a larger jump margin, enabling a common wheel speed sensor to be used for different models on the same platform.

[0004] Although the existing wheel speed sensor can adapt to the length change caused by the wheel jump through the spiral wheel speed sensor wire harness, it does not have protection for the spiral wire harness. During use, the spiral wire harness rubs against the wheel assembly bracket due to the wheel jump, resulting in damage and affecting the work of the wheel speed sensor in detecting the rotational speed and direction of the wheel in real time.
