Abstract

The present invention relates to a steer-by-wire steering device comprising: a slide bar that slides in an axial direction by a motor; a housing that accommodates the slide bar; and a damper formed in a ring shape and including a first support portion coupled to an inner circumferential surface of the housing and supported by the inner circumferential surface of the housing in a circumferential direction, and a second support portion coupled to the slide bar and supported by the slide bar in the circumferential direction. According to the embodiment, the number of parts is reduced by removing parts such as a pinion and a support yoke, and the shape and assembly process of the parts are simplified, so that the cost is reduced, the operation noise caused by friction between gears and the noise caused by reverse steering are reduced, the noise performance is improved, the friction during driving is reduced, and the durability of the parts is improved.

Description

technical field

[0001] The present embodiment relates to a steer-by-wire steering device, and more specifically, to a steer-by-wire steering device that reduces the number of parts by eliminating parts such as a pinion gear and a support yoke, and simplifies the shape of the parts and the assembly process , thereby reducing costs, reducing operating noise caused by friction between gears and noise caused by reverse steering to improve noise performance, reducing friction during driving, and improving durability of components. Background technique

[0002] The steer-by-wire steering device is a kind of electric steering device, which refers to a device that uses electric power to steer the vehicle without mechanical connections such as steering columns and universal joints between the steering wheel and the front wheel steering device.

[0003] That is, the driver's steering wheel operation is converted into an electrical signal, and the electronic control device receives the...
