Shift collar for use in sensor arrangement of gear box of motor car to detect rotation speed of counter-shaft, has set of internal gears arranged at collar, and sensing region arranged at collar and arranged radially offset from sensor

摘要

The collar (10) has a set of internal gears (11) arranged at the collar. A sensing region (17) is arranged at the collar, and is arranged radially offset from a rotation speed sensor (15) of the collar, where the sensor is designed as a hall effect sensor or as a sensor based on an anisotropic magneto-resistive effect. The sensing region is formed in a layer that is embedded with the sensing elements, and is formed in a tooth of a sensor gearing (24). The sensing region is made of a magnetized region on the collar. Two sides of a driver groove (14) are provided with two sensing regions. Independent claims are also included for the following: (1) a sensor arrangement for a gear box (2) a gear box.
