Problems solved by technology

[0010] However, in the prior art described above, when the ball nut rotates to slide the rack bar, the resistance of the face plate and noise and vibration occur, which are the rack bar, the ball nut , the nut pulley, the bearing, and the rack housing
[0011] In addition, when the motor operates the conveyor belt, the ball nut and the nut pulley may be deformed or damaged due to the shock transmitted to the ball nut and the nut pulley, or the The shock transmitted through the rack bar locks the steering wheel while driving causing a serious safety problem

Abstract

The present invention provides a rack assist type electric power steering apparatus that may include: a ball nut configured to be coupled to the outer circumferential side of a rack bar through balls that are coupled to a screw thread formed on the inner circumferential surface; a nut pulley configured to be coupled to the outer circumferential surface of the central portion of the ball nut in the axial direction; and a rotational support member configured to be coupled between the outer circumferential surface of the ball nut and the rack housing while supporting both side ends of the nut pulley.

Description

technical field [0001] The present invention relates to a rack-assisted electric steering device, in particular to a rack-assisted electric steering device, which can reduce the vibration noise and the resistance of the steering wheel, the resistance is due to a ball nut and a caused by the vibration generated by the operation of the rack bar, or by the impact load input from the reverse direction of the road surface; and improved driving reliability. Background technique [0002] A general rack-assisted electric steering device configuration includes a steering system having a structure from a steering wheel to wheels on both sides, and an auxiliary power mechanism for supplying steering auxiliary power to the steering system. [0003] figure 1 is a schematic partial cross-sectional view illustrating a typical rack-assisted electric power steering device, and figure 2 It is a partial cross-sectional schematic diagram illustrating a part of a general rack-assisted electri...
