Description

BACKGROUND OF THE PRESENT DISCLOSURE Area of ​​the present disclosure

[0001] The present disclosure relates to a self-contained angular module. More precisely, it relates to a self-contained angular module configured to impart a large steering angle to a wheel by independently rotating a linkage and an axle drive link when an actuating force is exerted on the linkage, which is located between a fixed frame and the axle drive link. Description of the state of the art

[0002] Conventional vehicle suspension connects the axle and body of the vehicle in such a way that vibrations or shocks absorbed by the axle from the road surface are not directly transmitted to the body while the vehicle is in motion, thus preventing damage to the body or its cargo and improving ride comfort. Such a suspension includes a spring designed to absorb shocks from the road surface, a shock absorber designed to improve ride comfort by suppressing free oscillations of the spring, and an anti-roll bar designed to prevent body roll.

[0003] The suspension system used for commercial vehicles is mainly an integral axle suspension, in which the left and right wheels are connected by one axle, and the suspension spring is mainly a leaf spring or an air spring.

[0004] Meanwhile, a steering system of a commercial vehicle that uses an integral axle suspension comprises a steering arm mounted on an output shaft of a steering gear to rotate with it, a trailing arm designed to transmit the movement of the steering arm, a steering knuckle designed to manipulate a steering spindle by receiving the movement of the trailing arm, a tie rod connecting the left and right steering knuckles, and the like.

[0005] Fig. Figure 1 shows a suspension system in which an end part of a shock absorber is attached to the frame of a vehicle body.

[0006] In a vehicle with integral axle suspension and steering, where the air spring described above is used, the air spring merely serves as a replacement for the leaf spring and does not significantly contribute to improving ride comfort or handling. Furthermore, due to the structural properties of the air spring, it is difficult to guarantee design freedom in implementing precise geometry.

[0007] Recently, a self-contained steering suspension was developed, designed to transmit the steering angle of a wheel to individual suspension components via a motor assembly. However, the self-contained steering suspension described above had the problem that the torque applied by the steering motor could not be stably transmitted to the steering knuckle and wheel.

[0008] Furthermore, DE 10 2018 213 156 A1 discloses a vehicle device comprising at least one vehicle frame element and at least one wheel steering angle adjuster movably arranged on the vehicle frame element for changing the steering angle of at least one vehicle wheel. The vehicle device includes at least one actuating unit designed to move the wheel steering angle adjuster relative to the vehicle frame element from at least one first operating position to at least one second operating position and vice versa.

[0009] DE 10 2018 118 615 A1 describes a relative guidance device for a steering assembly arranged on the wheel carrier side, as well as for spatially guiding and maintaining the relative spatial orientation of the steering assembly to a vehicle body, with at least one telescopic movement device for movably connecting the steering assembly arranged on the wheel carrier side to the vehicle body. Furthermore, a steering force transmission device for transmitting a steering force to a wheel of a vehicle with a relative guidance device, as well as a wheel suspension for a vehicle, in particular for a motor vehicle, with a steering force transmission device and a relative guidance device, are described.

[0010] Furthermore, DE 10 2014 004 231 A1 discloses a steering device for a motor vehicle for pivoting at least one steerable vehicle wheel, which is sprung on a suspension relative to a chassis of the motor vehicle, wherein the steerable vehicle wheel is rotatably mounted on a steering knuckle, and the steering knuckle is rotatably mounted in at least one pivot bearing on the suspension about a pivot axis, with at least one actuator motor having a rotatable output shaft, and wherein the at least one actuator motor is fixedly arranged on the chassis, wherein an articulated shaft is provided which is non-rotatably connected on one side to the output shaft of the actuator motor and which on the other side carries a toothing which engages with a mating toothing which is non-rotatably connected to the steering knuckle in such a way that a rotation of the output shaft of the actuator motor causes a rotation of the steerable vehicle wheel about the pivot axis.

[0011] The information contained in this background of the present disclosure is intended only to improve the understanding of the general background of the present disclosure and should not be construed as an acknowledgment or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

[0038] The following section refers in detail to various embodiments of the present disclosure(s), examples of which are illustrated in the accompanying drawings and described below.

[0039] The following are detailed descriptions of embodiments of the present disclosure with reference to the accompanying drawings. The exemplary embodiments of the present disclosure can be modified in various ways, and the scope of protection of the present disclosure must not be interpreted as being limited to the following embodiments. The exemplary embodiments are provided to more fully illustrate an exemplary embodiment of the present disclosure to the person skilled in the art.

[0040] Furthermore, terms such as "... joint", "... connection", "... part", "... frame", etc., used in this description, each refer to a unit that performs at least one function or operation and can be implemented as hardware or a combination thereof.

[0041] The exemplary embodiment of the present disclosure is described in detail below with reference to the accompanying drawing figures, and in the description given with reference to the accompanying drawing figures, the same or corresponding components are provided with the same reference numerals, and a description of these is not repeated.

[0042] Various embodiments of the present disclosure relate to an independent angle module. In the case of a multi-wheeled vehicle, the independent angle module can be coupled individually to a vehicle body, and the independent angle module can have a steering angle range of 90 degrees in the left and right directions.

[0043] The self-contained angle module can be attached to the vehicle body by welding or bolting and conducts power from a battery located in the vehicle body to enable the power supply from the vehicle body to a steering control element 100. As described above, the self-contained angle module can be conductively connected to the vehicle while being attached to the vehicle body using a standard procedure.

[0044] The independent angle module is described below according to various exemplary embodiments of the present disclosure with reference to a configuration comprising a wheel 500 located on the left side of the vehicle.

[0045] Fig. Figure 2 shows the independent angle module, and Fig. Figure 3 shows a coupling relationship between a fixed frame 300 and an axle gear link 200 with the link 100 located between them.

[0046] As shown, the independent angle module comprises the wheel 500, which is positioned so that it points towards the outside of the vehicle, and a steering knuckle 400 connected to the wheel 500. The independent angle module includes the axle drive link 200, which is located inside the steering knuckle 400 and connected to an end section of the steering knuckle 400. The independent angle module also includes the fixed frame 300, which is coupled to the vehicle body, and the link 100, which is positioned between the fixed frame 300 and the axle drive link 200 to apply an actuating force. In the present configuration, when the actuating force of the link 100 is applied, the axle drive link 200 can be moved integrally with the wheel such that the angle of rotation of the wheel is input.

[0047] The wheel 500 can be positioned on the outermost section of the steering knuckle 400, and an end section of the inner side of the steering knuckle 400 can be inserted into a vertical guide 230 of the axle gear link 200. Furthermore, the independent angle module includes a buffer 240, one end of which is connected to the steering knuckle 400 and the other end of which is attached to the axle gear link 200 to absorb any vertical movement exerted by the wheel.

[0048] In various exemplary embodiments of the present disclosure, the buffer 240 can be configured as a shock absorber or as a coil spring. Accordingly, the steering knuckle 400 is configured to move along the vertical guide 230 located in the axle gear member 200 to guide the vertical movement exerted by the wheel, and it is configured to absorb a shock exerted by the wheel 500 on the angle module by means of the configuration of the buffer 240 arranged between the steering knuckle 400 and the axle gear member 200.

[0049] The rotational force can be applied to the handlebar 100 via the motor 120, and the handlebar 100 is configured to rotate relative to the fixed frame 300 due to the generated actuating force. When the actuating force is applied to the handlebar 100, the axle drive link 200 is also rotated relative to the handlebar 100.

[0050] The steering link 100 surrounds at least a portion of the axle drive member 200 and at least a portion of the fixed frame 300 and includes a support member 110, which is configured to be movable along the fixed frame 300 when an actuating force is applied. Furthermore, the steering device 100 includes the motor 120, which vertically penetrates the support member 110, and the drive shaft of the motor 120 extends downwards to be coupled to the axle drive member 200 and the fixed frame 300, respectively. The motor 120 can be connected to the axle drive member 200 and the fixed frame 300 via a steering gear 130 located on the drive shaft of the motor 120.

[0051] The steering gear 130 can be rotated according to the rotation of the motor 120, and the support member 110 is moved along the fixed frame 300 relative to the fixed frame 300 in relation to the rotation of the motor 120. The axle gear member 200, which engages with the steering gear 130, can rotate relative to the steering gear 130. The axle gear member 200 can rotate about the central cross-sectional section of the wheel 500.

[0052] This means that when the rotational force of the motor 120 is applied, the link 100 and the axle drive link 200 can rotate simultaneously. The axis of rotation of the link 100 can be aligned with the axis of rotation of the axle drive link 200. Furthermore, the distance by which the link 100 moves along the fixed frame 300 can be equal to the distance by which the axle drive link 200 moves along the link 100.

[0053] The axle drive member 200 can comprise a link guide 210, which is at least partially surrounded by the support member 110 to guide the link 100, and can further comprise a gear 220 arranged on a surface of the link guide 210 to engage with the steering gear 130. The link guide 210 can have an arc shape in cross-section with respect to the central part of the wheel 500. The adjacent and mutually facing surfaces of the axle drive member 200 and the surface of the fixed frame 300 can have arc shapes with the same center point. Accordingly, the link 100, the axle drive member 200, and the fixed frame 300 can move relative to each other along the mutually facing arc-shaped surfaces.

[0054] The distance between the fixed frame 300 and the link guide 210 of the axle drive link 200 can be constant. The end section of the fixed frame 300 facing the steering link 100 can have an arc shape corresponding to that of the link guide 210 of the axle drive link 200. The steering gear 130 is provided in the gap between the axle drive link 200 and the fixed frame 300 and engages with both the axle drive link 200 and the fixed frame 300. Accordingly, the gear 220 and a frame gear 310 can each engage with the steering gear 130 so that the axle drive link 200 and the steering link 100 can move together in response to the actuation of the steering gear 130.

[0055] The support member 110 can be positioned between an arc-shaped section of the link guide 210 and an end section of the fixed frame 300, which has a shape corresponding to the arc shape of the link guide 210. The support member 110 can surround at least part of an end section of the axle drive member 200 and at least part of an end section of the fixed frame 300 adjacent to the axle drive member 200. If the steering gear 130 is rotated by the motor 120, the support member 110 can also move in response to the movement of the steering gear 130.

[0056] The frame gear 310 of the fixed frame 300 and the gear 220 of the axle drive 200, both of which engage with the steering gear 130, can each be a toothed type with the same interval, whereby the rotation of the steering link 100 and the rotation of the axle drive link 200, both of which correspond to the rotation of the steering gear 130, can be the same.

[0057] If the handlebar 100 is positioned at one of the opposite end sections of the frame gear 310 of the fixed frame 300, then the steering gear 130 of the handlebar 100 can therefore be positioned at a corresponding opposite end section of the gear 220 of the axle drive link 200. When the handlebar 100 is moved into the position described above, the wheel 500 is moved so that it has a maximum steering angle of 90 degrees either to the left or to the right.

[0058] Conversely, the frame gear 310 of the fixed frame 300 and the gear 220 of the axle drive link 200, each meshing with the steering gear 130, can be gears with different distances between them. However, if the wheel 500 is positioned so that it has the maximum steering angle, the steering arm 100 can be positioned at one of the opposite end sections of the frame gear 310 of the fixed frame 300, and the steering gear 130 of the steering arm 100 can be positioned at a corresponding opposite end section of the gear 220 of the axle drive link 200.

[0059] Fig. Figure 4 shows various exemplary embodiments of the present disclosure, illustrating the configuration inside the support member 110 of the steering arm 100.

[0060] As shown, the support member 110 can enclose at least part of the arc-shaped link guide 210 and at least part of an end section of the fixed frame 300 spaced apart from the link guide 210, which has a shape corresponding to the link guide 210.

[0061] Furthermore, the support member 110 can have an opening on one side through which the axle drive member 200 passes, and an opening on another side through which the fixed frame 300 passes. Accordingly, the distance between an end section of the link guide 210 and an end section of the fixed frame 300 facing that end section of the link guide 210 can be kept constant by means of the support member 110.

[0062] Furthermore, the steering gear 130, located within the support member 110, can be rotated by the actuating force of the motor 120, which is located at the upper end section of the support member 110, and the steering gear 130 can move along one end section of the fixed frame 300. Additionally, the axle gear member 200 is configured such that one end section of the axle gear member 200 rotates along the support member 110 when the rotational force of the steering gear 130 is applied.

[0063] The support member 110 can include a first roller 111 which is arranged inside the support member 110, on side surfaces of the fixed frame 300, the support member 110 and the axle gear member 200 which face each other.

[0064] Furthermore, the first roller 111 on the support member 110 can be provided on at least one of the side surfaces of the support member 110 and the side surfaces of the axle drive member 200 facing each other, and on at least one of the side surfaces of the fixed frame 300 and the side surfaces of the support member 110 facing each other.

[0065] This means that the first roller 111 can be located on the inside of the support member 110 that surrounds the axle drive member 200, or on the inside of the opening through which the axle drive member 200 passes. Furthermore, the first roller 111 can be arranged on the inner side surface of the support member 110 that surrounds the fixed frame 300, or on the inner side surface of the opening through which the fixed frame 300 passes.

[0066] Furthermore, the support member 110 comprises a second roller 112, which is arranged on at least one of the vertical upper end sections and the vertical lower end section of the support member 110. At least one second roller 112 can be provided on vertically opposite end sections of the axle drive member 200 that are opposite the support member 110, and at least one second roller 112 can be provided on vertically opposite end sections of the fixed frame 300 that are opposite the support member 110.

[0067] Accordingly, when the support member 110 is moved by the actuating force, it can be moved in a state of low friction between the support member 110 and the axle drive member 200 or the fixed frame 300, thanks to the first roller 111 and the second roller 112.

[0068] Fig. Figure 5A shows various exemplary embodiments of the present disclosure and illustrates a coupling relationship in the state in which the steering angle of the independent angle module is 0 degrees.

[0069] The independent angle module is designed to adjust the steering angle of wheel 500 depending on the user's steering inputs or the driving environment. Furthermore, the independent angle module provides power to operate the handlebar motor 120 at the steering angle set as described above.

[0070] As shown, at a steering angle of 0 degrees, the control arm 100 of the independent angle module attached to the vehicle body is located in the center of the frame gear 310 of the fixed frame 300 and the steering wheel 130 is located in the center of the gear 220 of the axle gear link 200.

[0071] Fig. 5B shows the independent angle module in a state where the steering angle is 90 degrees to the left.

[0072] In the state where the steering angle is 90 degrees to the left, the steering gear 130 is positioned in cross-section at the upper end section of the frame gear 310 of the fixed frame 300, and the position of the lower end section of the gear 220 of the axle gear link 200, which engages with the steering gear 130, is switched to a position facing the steering gear 130.

[0073] Accordingly, the wheel 500 can have a maximum steering angle to the left with respect to the longitudinal direction of the vehicle. Furthermore, in various exemplary embodiments of the present disclosure, the independent angle module can be controlled such that it has an angle of 90 degrees to the left.

[0074] Fig. In contrast, 5C shows the independent angle module in a state where the steering angle of the wheel is 500 90 degrees to the right.

[0075] As shown, in the state where the steering angle is 90 degrees to the right, the steering gear 130 is positioned in cross-section at the lower end section of the frame gear 310 of the fixed frame 300, and the position of the upper end section of the gear 220 of the axle gear link 200, which engages with the steering gear 130, is switched in cross-section to a position facing the steering gear 130.

[0076] Accordingly, in an exemplary embodiment of the present disclosure, the independent angle module can have a maximum steering angle to the right, and as shown, the independent angle module is provided at an angle of 90 degrees to the right in various exemplary embodiments of the present disclosure.

[0077] Fig. Figure 6 shows various exemplary embodiments of the present disclosure, illustrating the amount of rotation of the individual components to which the steering angle of the vehicle is applied.

[0078] In the case of the independent angle module of the present disclosure, the end section of the axle gear member 200, which is surrounded by the support member 110 of the link 100, has an arc shape, and the central shaft of the arc-shaped axle gear member 200 is the central section of the wheel 500 in cross-section.

[0079] Furthermore, an end section of the fixed frame 300 also has a shape that corresponds to the arc shape of the axle gear member 200, and the central shaft of the fixed frame 300 is formed in cross-section on the central section of the wheel 500.

[0080] Accordingly, the steering angle θs applied to wheel 500 is determined by the following equation. θp / θo=(Rs+Ro)Rp θs×Rs=θp×Rp=θo×(Rs+Ro) (θp = rotation angle of the handlebar 100, θo = rotation angle of the handlebar 100 from the center section of the wheel 500, Rs = distance from the center section of the wheel 500 to the end section of the axle drive link 200, which is in contact with the handlebar 100, Ro = distance from the center section of the wheel 500 to the end section of the fixed frame 300, which is in contact with the handlebar 100, and Rp = radius of rotation of the handlebar 100)

[0081] According to equation 1, the steering angle can be determined by multiplying the sum of the distance between the middle part of the wheel 500 and the end part of the axle gear link 200, which is in contact with the control arm 100, and the distance between the middle part of the wheel 500 and the end part of the fixed frame 300, which is in contact with the control arm 100, by the rotation angle of the control arm 100 from the middle part of the wheel 500 and dividing the result by the distance between the middle part of the wheel 500 and the end part of the axle gear link 200, which is in contact with the control arm 100.

[0082] This means that the arcuate end section of the axle drive member 200 and the arcuate end section of the fixed frame 300, which is provided at a position corresponding to the axle drive member 200, can rotate about the central section of the wheel 500, which is the central shaft of the axle drive member 200 and the fixed frame 300. Accordingly, the steering angle can be determined by the relationship between the arcuate end section of the axle drive member 200, the radius of the arcuate section of the fixed frame 300, which is provided at a position corresponding to the axle drive member 200, and the turning radius of the steering arm 100.

[0083] As can be seen from the above description, the present disclosure can achieve the following effects through the configuration, combination and actuation relationship described above with the exemplary embodiment of the present disclosure.

[0084] The present disclosure results in the wheel being given a larger steering angle by rotating the steering link and the axle drive element independently of each other.
