Problems solved by technology

[0004] However, in the case of such a steer-by-wire type steering apparatus, since there is no mechanical connection between the steering shaft and the wheels, there may be a problem that the driver's steering wheel rotation can be operated infinitely, thereby deteriorating the driver's steering feel

Abstract

The present embodiments relate to a steer-by-wire-type steering apparatus, and may provide a steer-by-wire-type steering apparatus comprising: an outer member which is rotated by a driving motor and has oblique grooves formed in the inner circumferential surface thereof; an inner member which is formed in a cylindrical shape and spaced inward from the inner circumferential surface of the outer member, fixed to a steering column, and provided with a guide part open in a radial direction; a sliding member, of which the outer surface is supported by the oblique grooves when the outer member rotates, and which moves along the guide part in an inward radial direction; and a support member which moves in the radial direction in association with the sliding member, and which supports the outer circumferential surface of the steering shaft and thereby prevents the steering shaft from rotating.

Description

technical field [0001] The present embodiment relates to a steer-by-wire steering apparatus, and more specifically, to a steer-by-wire steering apparatus capable of turning the steering wheel when the wheel rotation reaches the maximum point or when the driver generates more torque on the steering shaft than the reaction torque of the reaction motor. Prevents the steering shaft from rotating during high steering torque, thereby improving the driver's steering feel and steering stability. Background technique [0002] In general, power steering is developed and applied to provide convenience in driving operation by assisting the driver's steering wheel operation power, and the power steering is developed and applied as a hydraulic type using hydraulic pressure, an electric type using both hydraulic power and motor power Hydraulic types as well as electric types that use only motor power. [0003] Recently, steer-by-wire (SBW) type steering devices have been developed and app...
