Abstract

An electronic power-assisted steering system steering spindle, including input shaft 10, output shaft 11, torsion bar 12. Installation location and overload protection functions can be realized for torque rotation angle compound sensor 13. The moment torsion rotor 5 of torque rotation angle sensor 13 matches the input shaft 10 by key 14, the sensor position rotor 4 matches the output shaft 11 by key 15, and the fitting surface 16 of output shaft 11 and sensor 13 is knurl roll. Both ends of torsion bar 12 respectively interference fits with the input shaft 10 and the output shaft 11 hole. Angle of input shaft 10 between the tip plane6 and the tip plane 7 which fit the output shaft 11 is 168 degree, and the tip is the central symmetry shape. Output shaft 11 fits output shaft 10 are plane 8, plane 9.

Description

technical field

[0001] The invention relates to a steering shaft of an electric power steering system, which is used for installing a torque angle sensor so as to realize precise positioning and overload protection of the torque angle sensor, and belongs to the field of transportation tools. Background technique

[0002] The electric power steering system is a new type of power steering system that has appeared in recent years. It is mainly composed of sensors, control devices, reduction mechanisms and executive motors. One of the most important points is that the signal sent by the sensor on the rotating shaft must truly reflect the torque and steering angle on the rotating shaft.

[0003] Usually, in the design of the steering shaft of the electric power steering system, most of them design a sensor transmission mechanism, that is, a sliding sleeve is arranged on the upper steering shaft, and an annular groove is arranged on the outer peripheral surface of the sliding slee...
