Description of the state of the art

[0003] Generally, the steering device of a vehicle is equipped with a hydraulic device, a motor or a reduction gear to steer the wheels of the vehicle according to the driving conditions of the vehicle, and it is usually operated on the rear wheels of a general vehicle or on the front and rear wheels of a steer-by-wire system.

[0004] In a vehicle's steering system, the axial movement of an actuator rod is measured by a sensor that detects the movement of a magnet. The sensor can measure the displacement of an object moving in a linear reciprocating motion, and an electronic control device can stably control the vehicle's steering based on the sensor information.

[0005] However, the steering device of the vehicle may have the problem that the steering device cannot accurately measure the change of the axial displacement of the actuator rod due to reasons such as the fixing structure of the magnet, the sensor and the peripheral components, so that the accuracy of the steering angle measurement is reduced.

[0006] Furthermore, if the shocks and vibrations transmitted from the road surface continue while the vehicle is in motion, noise and vibration can increase, and the accuracy of steering angle measurement can drastically decrease. Therefore, a way to improve the service life of the steering device is needed. DEMOLITION

[0019] Firstly, with reference to Fig. 1 to Fig. 8, a steering device 100 of a vehicle according to the present embodiments includes an actuator rod 120 having a mounting hole 123 provided on one side of an outer surface and sliding axially, a rod mounting member 150 having one end coupled to a magnet assembly 170 and the other end coupled to the mounting hole 123, a rod housing 101 having a rod hole 104 through which the actuator rod 120 slides and a receiving hole 135 communicating with the rod hole 104 and provided on one side of an outer surface, a pair of support members 140 supporting both inner sides of the receiving hole 135 and coupled to slide axially together with the actuator rod 120, and separately arranged on both radial sides of the rod mounting member 150, and an elastic member 160,which is coupled to an outer surface of the rod fastening element 150 and elastically supports the pair of support elements 140.,

[0020] In the steering device 100 according to the present embodiments, the actuator rod 120 performs the steering of the vehicle while performing a linear sliding movement in the axial direction, and a sensor assembly 110 detects a change in the magnetic field of the magnet 171 incorporated in the magnet assembly 170, which performs a linear sliding movement together with the actuator rod 120, and transmits information about the change in the axial displacement to an electronic control device 107 to calculate a steering angle.

[0021] The actuator rod 120 is installed inside the rod housing 101 and moves linearly in the axial direction. The rod mounting member 150 and the support member 140 are connected to the actuator rod 120 and slide axially together with the actuator rod 120 within the rod housing 101.

[0022] The actuator rod 120 may be bolted to a ball nut (not shown) and slide axially through a belt (not shown) that transmits the drive force of a motor 105. The electronic control device 107 may control the operation of the motor 105 by calculating the steering angle based on the change in the magnetic field of the magnet 171 detected by the sensor assembly 110.

[0023] The motor 105, the belt and the ball nut may be installed in a driver housing 103 connected to one side of the rod housing 101, and a detailed description of these components is omitted.

[0024] The rod housing 101 and the driver housing 103 are provided with wheel connection angles 109a and 109b which are coupled to a road wheel, and with body mounting holes 101a and 103a for attachment to the vehicle body.

[0025] A flat surface 121 formed by cutting a flat surface is provided on one side of the outer surface of the actuator rod 120, and the fixing hole 123 is provided in the flat surface 121 to connect the rod fixing member 150.

[0026] Therefore, when the actuator rod 120 slides, the rod fixing member 150 can maintain the exact sliding direction at the exact position of the actuator rod 120.

[0027] As in the Fig. 3 and Fig. 4, the rod fastener 150 is coupled at the upper end to the magnet assembly 170 and at the lower end to the actuator rod 120 and slides axially together with the actuator rod 120.

[0028] As in Fig. 3, the rod housing 101 is provided with a rod hole 104 through which the actuator rod 120 slides, and is provided with the receiving opening 135 on one side of the outer surface, which is open upward and communicates with the rod hole 104.

[0029] The rod housing 101 has a box-shaped projecting receiving portion 102 formed on one side, and the receiving opening 135 is provided in the interior of the receiving portion 102.

[0030] Therefore, when the actuator rod 120 slides, the sensor assembly 110 can stably detect the change in the magnetic field of the magnet 171 at the nearest position.

[0031] The support member 140 may be formed as a pair that is separated and arranged on both radial sides of the rod fixing member 150 and can support the inner sides of the receiving hole 135 and can be coupled to slide in the axial direction together with the actuator rod 120.

[0032] In addition, the elastic member 160, which is connected to the outer surface of the rod fastening member 150, elastically supports the support member 140 on the inner sides of the receiving opening 135.

[0033] The annular elastic support member 160 may be made of one or more materials selected from the group consisting of NR (natural rubber), NBR (nitrile butadiene rubber), CR (chloroprene rubber), EPDM (ethylene propylene terpolymer), FPM (fluororubber), SBR (styrene butadiene rubber), CSM (chlorosulfonated polyethylene), PU (polyurethane), and silicone rubber.

[0034] Since the elastic member 160 continuously elastically supports the support member 140 on both inner sides of the receiving hole 135, noise and vibration caused by the play between the support member 140 and the receiving hole 135 can be prevented, and the accuracy of detecting the sliding position can be increased.

[0035] In the present embodiments, the elastic member 160 may be formed of NBR (nitrile butadiene rubber), which has oil, ozone, and weather resistant properties.

[0036] As in Fig. 5, the support member 140 may include a first support member 140a and a second support member 140b formed symmetrically and separately, and a coupling projection 141 may be provided on one side of the facing surfaces of the first support member 140a and the second support member 140b, and a coupling groove 142 coupled to the coupling projection 141 may be provided on the other side, or a coupling groove 142 may be provided on one side of the facing surfaces, and a coupling projection 141 coupled to the coupling groove 142 may be provided on the other side.

[0037] The coupling protrusion 141 and the coupling groove 142 can fix the coupling position of the first support member 140a and the second support member 140b during assembly, while preventing displacement due to the elastic force of the elastic member 160 when the actuator rod 120 slides and maintaining the correct position.

[0038] The support member 140 may be made of one or more materials selected from the group consisting of polyacetal (POM), polyamide (PA), polycarbonate (PC), polyimide (PI), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), and phenol formaldehyde (PF), and may be formed by blending 20 to 60 wt.% glass fibers.

[0042] Furthermore, the support grooves 148 may be filled with a lubricant to minimize friction with the inside of the receiving opening 135 of the rod housing 101 when the support member 140 slides in the axial direction. To be clear, filling the interior of the support grooves 148 with the lubricant does not imply that the support grooves 148 are exclusively "filled" with the lubricant and exclude other materials. The term "filled with" as used herein is intended to encompass a broad spectrum of conditions, including, but not limited to, "partially filled with," "substantially filled with," "fully filled with," or "exclusively filled with."

[0043] With reference to Fig. 5 to Fig. 8, the rod fastening element 150 may comprise a body element 151 having a fastening projection on the outer surface 154 which projects radially and is fixed to the flat surface 121, a screw fastening part 153 which is arranged on the underside of the fastening projection 154 and has a screw portion 153a formed on the outer surface to be coupled with the fastening hole 123, and a head part 155 which is arranged on the upper side of the body element 151 and has a tool fastening surface 156 formed on the outer surface.
