Hub bearing with built-in sensor rotor
The structure of a traditional wheel bearing is given. A sensor element is used to detect the sensor rotor signal to measure the wheel speed. A metal sintered block or a turning gear-type sensor rotor is mounted on the rotating part. The press fit is installed on the outer ring of the constant velocity universal joint of the driving wheel or the outer ring of the bearing for the non-driving wheel. This structure (driving and non-driving) of the wheel speed sensor is mounted on the steering knuckle
A passive sensor (a sensor that detects magnetic flux) is a commonly used sensor. When the sensor rotor rotates, the change in magnetic flux in the passive sensing unit causes the sensing element to generate a sinusoidal current. As the rotor speed increases, the frequency and voltage also increase. However, the frequency and voltage are directly proportional to the rotor speed, so it is difficult to measure the wheel speed at low speeds due to the low frequency.
Multi-pole magnetic encoder seals (multi-pole magnetic rubber vulcanized on metal rings) are more commonly used than gear-type sensor rotors. Due to the integrated design with the seal ring, the multi-pole magnetic encoder seal ring is much lighter than the traditional sensor rotor. Fewer parts reduces the size and weight of the sensor rotor. Multi-pole magnetic encoders facilitate the use of active sensing elements such as magnetoresistive element (MRE) rotation sensors and Hall-effect sensors. Magnetoresistive element rotation sensors have no restrictions on the speed of rotation, so they can measure wheel speeds that are almost stationary. Unlike traditional magnetic induction sensors, the magnetoresistive element is integrated with the multi-pole magnetic encoder seal ring, making the hub bearing structure more compact. Figure 7 shows examples of first and second generation hub bearings with multi-pole magnetic encoder seals.
