Problems solved by technology

The PCB assembly is fixedly connected to the upper casing, and the PCB board is clamped between the lower casing and the input shaft rotor. The upper casing and the lower casing are connected by laser welding, and the process is complicated.
In addition, the rotor is produced by overmolding and connected to the input shaft by laser welding, which often leads to problems of inaccurate positioning during fixation and movement or complex processes

Abstract

The invention provides an automobile power-assisted steering sensor which comprises an upper shell, a lower shell, an input shaft rotor, a PCB assembly and an output shaft rotor, wherein the input shaft rotor is installed on an input shaft of an automobile power-assisted steering device, and sleeves the upper portion of the upper shell, the PCB assembly is installed at the lower portion of the upper shell, the upper shell and the lower shell are in fastened connection, the PCB assembly is fixed in space formed by the upper shell and the lower shell, the input shaft of the automobile power-assisted steering device is sleeved with the upper shell, the output shaft rotor is installed at the output shaft of the automobile power-assisted steering device, when the automobile power-assisted steering device is operated, the input shaft rotor and the input shaft rotate coaxially at the same speed, the output shaft rotor and the output shaft rotates coaxially at the same speed, and therefore theupper shell and the input shaft rotor are kept concentric and coaxial. By improving the structure of the upper shell and the input shaft rotor, the assembling technology of the sensor is simplified,the stability of the sensor is improved, and the excellent market prospect is achieved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto power steering sensor. Background technique [0002] Automobile power steering is to increase the external force to resist the steering resistance, so that the driver can complete the steering with less force, also known as power steering, which makes driving easier and more relaxed, and makes the vehicle more responsive. To a certain extent, the security has been improved, and it has been widely valued. The power steering sensor of the car detects the magnitude and direction of the torque or the angle of rotation generated by the steering wheel when the driver is operating the steering wheel, and converts the required information into a digital signal input to the control unit, and then the control unit calculates these signals to obtain a driving The torque that is suitable for the working conditions is finally issued to drive the motor to work, and the output torque of the m...
