Problems solved by technology

[0005] However, there are certain difficulties in the installation of magnetic induction sensors with more reliable work. The installation space under the steering wheel is limited, and components such as clock spring mechanisms and combination switches need to be installed, especially when installing magnetic induction sensors. Axial positioning mechanisms, such as the simple cooperation between the boss and the groove, the opening stop ring, etc., often interfere with the installation so that the magnetic induction sensor cannot be installed, and the positioning pin is used for positioning, because the pin hole and the positioning pin cannot ensure alignment, so there is no guarantee that the installation process will go smoothly

The steering wheel steering angle sensor device comprises a base (2), a first gear (1), a second gear (5), a third gear (4), a first magnet (6), a second magnet (3), a first magnetic inductive sensor (7) and a second magnetic inductive sensor (8), wherein the base is provided with three positioning grooves (21, 22 and 23); the first gear (1) is arranged in the first positioning groove (21); the second gear (5) is arranged in the second positioning groove (22); the third gear (4) is arranged in the third positioning groove (23); the first magnet (6) is fixed on the second gear (5); the second magnet (3) is fixed on the third gear (4); the first magnetic inductive sensor (7) and the second magnetic inductive sensor (8) are arranged on the base (2); the second gear (5) and the third gear (4) are in meshed connection with the first gear (1) respectively; the positions of the first magnet (6), the second gear (5) and the first magnetic inductive senor (7) are aligned; and the positions of the second magnet (3), the second magnetic inductive sensor (8) and the third gear (4) are aligned.

Description

technical field [0001] The invention relates to a steering wheel steering angle sensor device for an automobile electronic stability system (ESP), in particular to a steering wheel steering angle sensor device including a rotation angle sensor. Background technique [0002] As is known, the ESP electronic body stabilization system consists of a control unit, a steering sensor (monitoring the steering angle of the steering wheel), a wheel sensor (monitoring the speed rotation of each wheel), a sideslip sensor (monitoring the state of the car body rotating around the vertical axis), lateral acceleration Sensors (monitoring the centrifugal force of the car when turning) and other components. The control unit judges the running state of the vehicle through the signals of these sensors, and then issues control commands. During the driving process of the car, the steering sensor senses the turning direction and angle that the driver is trying to operate, the wheel sensor senses t...
