The invention relates to a vehicle with a steering angle sensor. The vehicle comprises a chassis that is moveable in a driving direction, two rear wheels moveably carrying the chassis on the rear sideseen in the driving direction, two front wheels moveably carrying the chassis on the front side seen in the driving direction, a steering wheel for turning a steering column around a rotation axis for steering the front wheels, and a steering angle sensor for measuring a rotation angle of the steering column around the rotation axis with an encoder that is stationary to the steering column and with a magnet sensor that is disposed axially displaced from the encoder on the rotation axis, wherein the encoder includes a first magnet with a top side directed to the magnet sensor and a second magnet attached to the first magnet opposite to the top side, wherein at least the first magnet includes a recess starting from the top side, wherein each magnet is magnetized orthogonal to the rotation axis, and wherein regarding from the magnetizations, the first magnet and the second magnet are displaced against each other in rotation direction, characterized in that the recess has a depth that islower than an axial thickness of the first magnet.
本发明涉及一种带有转向角传感器的车辆,包括底盘、两个后轮、两个前轮、方向盘和转向角传感器。底盘可在行驶方向上移动,后轮和前轮可移动地承载底盘,方向盘用于绕着旋转轴线转动转向柱,以使前轮转向。转向角传感器用于利用固定于转向柱的编码器并且利用磁体传感器来测量转向柱绕着旋转轴线的旋转角度,磁体传感器被设置为从旋转轴线上的编码器轴向位移。编码器包括第一磁体以及第二磁体,第一磁体顶侧指向磁体传感器;第二磁体与顶侧相反地附接到第一磁体,至少第一磁体包括从顶侧开始的凹部,每个磁体垂直于所述旋转轴线磁化,并且相对于磁化,所述第一磁体和所述第二磁体在旋转方向上相对彼此位移。凹部的深度小于第一磁体的轴向厚度。
