The invention discloses a sensor for measuring the steering angle of a vehicle, and belongs to the technical field of steering angle sensors, the sensor comprises a sensor shell, a sensor plug, a reduction gear set and two infrared geminate transistors, the reduction gear set is arranged in the sensor shell, and the sensor plug is hinged to the sensor shell; according to the invention, the sensor plug is connected into the rotating shaft to be measured, the sensor plug rotates when the vehicle turns, the weak rotation angle of the sensor plug is amplified under the amplification action of the reduction gear set, and the infrared geminate transistors are used for performing correlation signal acquisition frequency measurement. The rotation angle of the output gear of the reduction gear set can be calculated by calculating the rotation angle of the output gear of the reduction gear set, and then the rotation angle of the input end of the reduction gear set, namely the rotation angle of the sensor plug, can be deduced, the durability of the sensor is greatly improved, the sensor is not prone to damage, and the manufacturing cost and the manufacturing difficulty of the sensor are reduced.

    本发明公开了一种测量车辆转向角度的传感器,属于转向角传感器技术领域,包括传感器外壳、传感器插头、减速齿轮组和两个红外线对管,所述减速齿轮组设于所述传感器外壳的内部,所述传感器插头铰接在所述传感器外壳上;本发明通过将传感器插头接入到待测量的旋转轴中,车辆转向时传感器插头发生转动,在减速齿轮组的放大作用下,传感器插头微弱的转动角度将会被放大,并通过红外线对管进行对射信号获取频率测量,即可计算出减速齿轮组输出齿轮的转动角度,进而可以推演出减速齿轮组输入端的转动角度,即为传感器插头的转动角度,机械结构设计,大大地提高了传感器的耐久性,使得传感器不易损坏,降低传感器的制造成本和制造难度。
