The invention discloses a tolerance compensation ring of a speed reduction mechanism suitable for an electric power steering system. The speed reduction mechanism comprises a worm gear and a worm which are engaged. The tolerance compensation ring comprises an outer supporting ring, an inner supporting ring arranged in the outer supporting ring, a connecting block connected with the outer supporting ring and the inner supporting ring, a first supporting block arranged on the outer supporting ring and used for providing the supporting action for the inner supporting ring in the first direction,and a second supporting block arranged on the outer supporting ring and used for limiting the inner supporting ring in the second direction, the first direction is parallel to the axis of the worm gear, and the inner supporting ring is provided with a center hole for the worm or a bearing to be inserted. According to the tolerance compensation ring of the speed reduction mechanism suitable for theelectric power steering system, the manufacturing tolerance of a speed reduction box body, the worm gear and the worm can be eliminated, and speed reduction mechanism manufacturing tolerance compensation is achieved.
Description
technical field [0001] The invention belongs to the technical field of electric power steering, and in particular relates to a tolerance compensation ring suitable for a deceleration mechanism of an electric power steering system. Background technique [0002] Generally, electric power steering is used on most cars. This electric power steering system is based on the ECU controller to control the rotation of the EPS motor according to the changes of the collected sensor torque signal and angle signal. Steering performance. That is, the EPS steering system is used to improve the motion stability of the vehicle by utilizing the power of a separate EPS motor to assist the steering of the vehicle. [0003] Traditionally, hydraulic pressure has been used in auxiliary steering devices, but from the viewpoint of reducing engine load, reducing weight, improving steering stability, and quick return force, recently, the use of a motor suitable for transmitting the rotational output ...
