The latest technology in the automotive industry has allowed car owners to brave the road with more safety features than ever before. This includes the advancement in the wheel speed sensor installed in most modern vehicle models that are widely used by most car owners today. The wheel speed sensor or also known as the ASB sensor monitor is responsible for the operation of the wheel\u2019s rotation.<\/p>\n
It\u2019s a data-collection device that measures the speed of the wheel and transmits data to systems that control the dynamics of the vehicle including the brakes, transmission, and drive axles. In an instance, if the wheel speed sensor notices that the vehicle\u2019s wheels on the same axle don\u2019t work at the same speed together, it sends a signal to the ABS which then would determine if anti-lock braking is required to prevent major, catastrophic consequences.<\/p>\n
The passive sensor in wheel bearings has sailed past its prime. Through the years, the\u00a0bearing technology\u00a0has adapted to the modern technology requirements of modern vehicle models. The latest available technology made it possible for the Active Sensor Technology (ASB) to supersede the Passive sensor.<\/p>\n
For example, the active sensor delivers a signal with constant amplitude and can detect even very low speeds which the former wasn’t capable of. This guarantees precision in the use of the rotary speed signal thereby improves the function of all systems associated with it.<\/p>\n
To date, there are three different types of active sensors available:<\/p>\n
ACTIVE HALL EFFECT SENSOR<\/strong>\u00a0\u2013 It\u2019s comprised of a semi-conductor with an electronic circuit that converts the signal of the alternating current to a digital one.<\/p>\n ACTIVE HALL EFFECT SENSOR IN COMBINATION WITH A MAGNETIC ENCODER SEAL ON THE WHEEL BEARING<\/strong>\u00a0\u2013 its north and south poles generate a magnetic field of the magnetic encoder as it passes through the sensor.<\/p>\n ACTIVE MAGNETO-RESISTIVE SENSORS<\/strong>\u00a0\u2013 capable of detecting signal in complex arrangements despite the sensor\u2019s distance from the encoder seal.<\/p>\n More than its precise and accurate data acquisition capabilities, this solution offers more than just that. From ABS to ESC or even Navigation, this solution delivers data that affects the overall user safety:<\/p>\n NTN-SNR was the first to replace passive sensors (tone wheel and passive sensor) with an active sensor and seal with an embedded magnetic encoder, thanks to this technology.<\/p>\n ASB technology is used as original equipment<\/a> on over\u00a080% of vehicles worldwide<\/strong>\u00a0and\u00a090% of vehicles in Europe<\/strong>. Today,\u00a0100% of the available third generation of\u00a0<\/strong>wheel hub bearings<\/strong><\/a>\u00a0are equipped with this technology are manufactured with a global standard by the leading ASB bearings manufacturer. Additionally, an ASB Detector card can be helpful for you to manually and quickly check the magnetized seal likewise, the location of the sensor in the bearing.<\/p>\nKey advantages of choosing the ASB <\/strong>bearing technology<\/h2>\n
