Speed sensor integrated into a bearing cap

摘要

A speed sensor attached to a bearing for sensing a rotating speed of a wheel is provided. The speed sensor includes a thermoplastic bearing cap (1). A mounting ring (2) is connected to the cap (1). The mounting ring includes a flange portion (2B). A plastic body portion (5) is integrally molded into the cap (1) adjacent the mounting ring (2). An active sensor element (7) is located in a lower end of the body portion (5), a face of the active sensor element (7) being vertically spaced a predetermined distance from the flange portion (2B). A pair of terminals (3,4) is electrically connected to the active sensor element (7). The pair of terminals (3,4) extends from an upper end of the body portion (5). The flange portion (2B), when pressed onto an end face of a hub (11) associated with the wheel, is adapted to space the active sensor element (7) an operating distance from a tone wheel (17) mounted to a spindle (13).
