It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept as defined by the appended claims. The present invention is not limited to the following embodiments.

(Example 1)

The present embodiment has a plate, a guide member, and a bracket as a shock absorber for a cabin of a commercial vehicle.

Commercial vehicles are cars used in business, such as trucks, dump trucks, vans and buses. As shown in FIG. 1, the commercial vehicle includes a cabin 10 corresponding to a driver's seat or a passenger seat. The cabin 10 is subjected to an external force or vibration from the outside or the vehicle body during the operation. In the course of the operation, such an external force or vibration becomes very large, so that the driver or the passenger is much fatigued and the ride quality can be remarkably reduced.

The shock absorber is a device for buffering an external force or vibration acting on a cabin of a commercial vehicle, and is intended to drastically reduce fatigue and greatly improve ride comfort for a driver or a passenger. Illustratively, as shown in FIG. 1, the shock absorber 100 may be a pair of the lower left 11 and the right 12 of the cabin 10 of the commercial vehicle, respectively. However, the shock absorber 100 is not limited to a pair but may be composed of one or more than three shock absorbers. The shock absorber (100) supports an elastic member that elastically supports the cabin (10), thereby buffering external force or vibration acting on the cabin.

The resilient member elastically supports the cabin. The resilient member may be made of a device such as an air suspension arranged at the lower left 11 or right 12 of the cabin 10, illustratively as shown in Fig. However, the elastic member is not limited to the air suspension, but may be made of various other devices capable of elastically supporting the cabin 10. The end of the elastic member may be made of a cylindrical stud. Such an elastic member can be accurately and easily aligned on the plate by the ring-shaped guide member. The elastic member is supported by the plate of the shock absorber.

The plate supports the elastic member. Illustratively, as shown in Figures 2 and 3, the plate 110 has a body portion 111 having a flat surface. When the surface of the main body 111 is flattened, the end portion of the elastic member stably contacts the surface of the main body 111, so that the elastic member stably contacts the plate 110 in a stable manner. As shown in Fig. The body portion 111 is formed with a hole 112 through which the end of the elastic member is mounted. The hole 112 is formed not by punching the plate 110 but by the mold in the process of completing the entire plate 110. The hole 112 is formed around the hole 112 The surface of the main body 111 of the plate 110 is deformed to be not flat and the elastic member can be prevented from being unstably supported on the plate 110. Further, when the hole 112 is formed by the mold, the dispersion of the dimension of the hole 112 can be minimized, and the reliability of the quality can be ensured. A portion of the edge of the main body 111 that is not engaged with the bracket is formed of a bent portion 113 that forms a bend. The bent portion 113 improves the rigidity of the plate 110 during the process of coupling the plate 110 to the bracket or supporting the elastic member. A guide member is coupled to the plate.

The guide member is engaged with the plate to guide the elastic member to be aligned at a predetermined position of the plate. The guide member 120 is arranged so as to protrude outward from the surface of the plate 110, for example, as shown in FIG. Therefore, the elastic member can be accurately and easily guided by the guide member 120. Further, the inner surface of the guide member 110 is formed so as to guide and contact the outer surface of the elastic member closely. Therefore, the elastic member can be precisely guided by the guide member 120 so that it can be accurately arranged at a predetermined position of the plate 110.

The guide member may have various structures or shapes that can guide the elastic member to be aligned at a predetermined position of the plate. For example, when the guide member has a ring shape, it can guide the outer surface of the elastic member and align the elastic member with the plate very accurately and easily. 4, the guide member 120 may include a main body 121 formed in a circular ring shape and a guide hole 122 at the center. The main body 121 includes an outer surface 121a and an inner surface 121b. The inner surface 121b guides the outer surface of the elastic member (not shown) And is brought into close contact with the outer surface of the elastic member when the elastic member is held in contact with the elastic member. Thus, the guide member 120 having a circular ring shape can accurately align the elastic member with the predetermined position of the plate 110 by accurately guiding the outer surface of the cylindrical elastic member. If the end portion of the elastic member is formed of a cylindrical stud, the area of the guide member 120 having a circular ring shape and in close contact with the inner side surface 121b of the main body portion 121 can be maximized, The plate 110 can be more accurately aligned at a predetermined position and stably supported.

The guide member engages the predetermined position of the plate. The guide member 120 may be coupled to the plate 110 so that the guide hole 122 of the guide member 120 overlaps the hole 112 of the plate 110 as shown in FIG. The guide member 120 may be coupled to the plate 110 such that the guide hole 121 of the guide member 120 and the hole 112 of the plate 110 are concentric with each other. The elastic member is guided through the guide hole 121 of the guide member 120 so that the elastic member can be accurately attached to the hole 112 of the plate 110. [ However, the present invention is not limited thereto, and the guide member 120 can be variously arranged on one plate 110 that can precisely guide the elastic member and accurately align the plate 110 at a predetermined position. For example, when the portion of the elastic member mounted on the hole 112 of the plate 110 is not on the longitudinal center axis of the elastic member but on the eccentric axis, the guide hole of the guide member 120 122 and the holes 112 of the plate 110 can be arranged. Meanwhile, the guide member 120 can be coupled to the plate 110 by welding. Accordingly, the guide member 120 can be stably and easily coupled to the plate 110. The bracket is coupled to the plate to which the guide member is coupled.

The bracket engages with the plate to which the guide member is coupled and supports it on the commercial vehicle. 5, the bracket 130 includes a main body 131 coupled to the plate, a first coupling 132 disposed at both ends of the main body 131 and coupled to a commercial vehicle, And a second engaging part 133. [ 2, the main body portion 131 includes an inner side surface of the contour corresponding to the contour of the non-bending portion 113 corresponding to the edge excluding the bending portion 113 of the plate 110 131a. The inner surface 131a of the main body 131 of the bracket 130 can be accurately and easily coupled to the end surface of the non-bent portion 113 of the plate 110. [ The first coupling portion 132 may have at least one first coupling hole 134 for coupling to a part of a commercial vehicle, for example, a chassis, and the second coupling portion 133 may have at least one coupling hole 134 for coupling to another chassis of a commercial vehicle And may have at least one second coupling hole 135. The first and second coupling holes 134 and 135 may be a means for fixing the bracket 130 to connect the bracket 130 to the plate 110.

The step of preparing the guide member (S220) is a step of preparing a guide member for guiding the elastic member. The guide member can be prepared in various ways. For example, a guide member having a circular ring shape can be prepared by a metal mold. At this time, in the guide member, the inner diameter dimension is designed in consideration of the outer side dimension of the elastic member to be guided, and the thickness dimension can be set within a range that can maintain a predetermined strength for stably supporting the elastic member.

The step of joining the guide member to the plate (S230) is a step of joining the guide member to a predetermined position of the plate to guide the elastic member to be aligned at a predetermined position of the plate. The guide member is coupled to the plate surface so as to protrude outward. The guide member can be coupled to the plate by various methods. For example, the step of joining the guide member to the plate (S230) includes, as exemplarily shown in FIG. 7, a step of aligning the guide on the plate (S231) and a step of aligning the guide member And a step of welding (S232). Step S231 of aligning the guide on the plate may be performed by, for example, fixing the plate with a first jig, aligning and aligning the guide member to a predetermined position of the fixed plate, and then aligning the guide member with the second jig ). ≪ / RTI > The step (S232) of rotating the guide member aligned to the plate so as to be suitable for welding may be performed by, for example, rotating the first and second jigs in the welding of the plate and the guide member, The member itself may be rotated to be suitable for welding and then welded. Thus, the welding can be performed accurately and easily, so that the welding quality can be improved and the productivity of the welding work can be increased. At this time, the welding is performed by a welding system which is automatically controlled by the program, and the rotation of the guide member and the plate, which are aligned and fixed by the first and second jigs, can be controlled by a program have. As a result, the accuracy of the welding operation can be further improved, thereby improving the welding quality and improving the welding workability.

The step of preparing the bracket S240 may be variously performed. For example, in step S240 of preparing a bracket, a bracket material is prepared, then the bracket material is cut into a predetermined shape, and the cut bracket material is formed to have a contour corresponding to the contour of the cross section of the non- By forming the joint portions by bending both ends of the contours and then forming the joint holes at the joint portions at both ends.

The step of joining the bracket to the plate to which the guide member is coupled (S250) may be variously performed. For example, as illustrated in FIG. 8, a step S250 of coupling a bracket to a plate coupled with a guide member includes a step S251 of aligning a bracket to a plate to which the guide member is coupled, (S252) of rotating the bracket aligned on the coupled plate so as to be suitable for welding, and then aligning the upper welded plate bracket assembly so as to be suitable for the lower welding (S253) (S254) of rotating the lower plate bracket assembly to fit the welded plate bracket assembly and welding the lower plate.

The step (S251) of aligning the bracket with the plate having the guide member is performed by, for example, supporting the bracket by a first supporting device for supporting the plate to which the guide member is coupled, 2 supporting device. They may be made in a different order.

The step S252 of rotating the upper portion of the bracket aligned with the guide member to rotate the bracket so as to be suitable for welding may be performed by, for example, welding the bracket with the guide member to the first support device and the second support device Or by rotating the plate and the bracket itself, which are aligned and fixed by the guided member, thereby making it suitable for welding, and then welded to the surface of the guided member. Thus, the welding can be performed accurately and easily, so that the welding quality can be improved and the productivity of the welding work can be increased. At this time, the welding is performed by a welding system which is controlled automatically by the program, and the rotation of the bracket and the plate, to which the guide member aligned and fixed by the first and second support devices are coupled, Can be controlled by a program. As a result, the accuracy of the welding operation can be further improved, thereby improving the welding quality and improving the welding workability.

The step (S253) of aligning the upper welded plate bracket assembly to be suitable for the lower welding may be performed by, for example, aligning and supporting the plate and the bracket at the surface side where the guide member is engaged with the first support device and the second support device By separating the welded plate bracket assembly from the first support device and the second support device and turning it 180 degrees and then aligning and supporting it with the first support device or the second support device, It may be to make it ready for welding work. Or the plate bracket assembly is not separated from the first and second support devices, the first support device and the second support device are turned upside down by 180 degrees, resulting in the plate bracket assembly being turned upside down by 180 degrees So that the welding operation can be performed on the surface of the guide member and the opposite surface.

The step S254 of rotating the plate bracket assembly aligned for the lower welding to be suitable for welding and then welding the lower portion S254 may be carried out in a manner such that the upper welded plate and bracket are welded to the first and second support devices Or by rotating the plate bracket assembly itself so that it is suitable for welding, it can be welded on the surface side opposite to the surface to which the guide member is coupled. Thus, the welding can be performed accurately and easily, so that the welding quality can be improved and the productivity of the welding work can be increased. The welding is then welded by a welding system which is controlled automatically by the program and the rotation of the plate bracket assembly fixed by the first and second support devices can be controlled by a program to interlock with the movement of the welding system . As a result, the accuracy of the welding operation can be further improved, thereby improving the welding quality and improving the welding workability.

The buffer unit having the bracket coupled to the plate coupled with the guide member is finally completed through the above steps.
