DETAILED DESCRIPTION

[0033] Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that the present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.

[0034] FIG. 1 is a schematic diagram of a carrier for a suspension system of vehicles according to an exemplary embodiment of the present invention, FIG. 2 is a perspective view of the carrier for a suspension system of vehicles according to the exemplary embodiment of the present invention, and FIG. 3 is a front view of the carrier for a suspension system of vehicles according to the exemplary embodiment of the present invention.

[0035] Referring to FIGS. FIG. 1 and FIG. 2, as a carrier 1 for a suspension system of vehicles (hereinafter, referred to carrier) according to an exemplary embodiment of the present invention, a carrier for a rear wheel dual lower arm suspension system will be described as an example.

[0036] Here, the dual lower arm suspension system is a multi link type suspension system in which two arms are connected to a lower portion with respect to the carrier 1.

[0037] The carrier 1 rotatably supports the wheel to connect between a plurality of arms connected to a rear wheel side vehicle body and a wheel.

[0038] The carrier 1 is configured of a wheel bearing mounting part 10, an upper arm mounting part 20, a lower arm mounting part 30, a flat reinforcing part 40, a trailing arm mounting part 50, and an assist arm mounting part 60.

[0039] First, the wheel bearing mounting part 10 has a center provided with a through hole 12 for mounting a wheel bearing, in which an outside circumferential surface of the through hole 12 is provided with at least one fastening hole 13.

[0040] Four fastening holes 13 may be formed at positions where they are spaced apart from each other at a predetermined angle with respect to the through hole 12 and the fastening hole 13 is =mounted with a knuckle.

[0041] Further, an inner circumferential surface of the wheel bearing mounting part 10 is provided with a step part 15.

[0042] When the wheel bearing is mounted in the through hole 12, the step part 15 prevents the wheel bearing from being separated from the through hole 12.

[0043] Further, the upper arm mounting part 20 is formed at an upper portion of the wheel bearing mounting part 10 and fastened with an upper arm 21.

[0044] The upper arm mounting part 20 has a fork shape so that the upper arm bush unit 23 mounted at the upper arm 21 is mounted.

[0045] That is, the upper arm mounting part 20 includes two flanges that are formed at a first side and a second side with respect to a front and rear direction of the vehicle. The upper arm bush units 23 are inserted between the respective flanges and are bolt-fastened with each other.

[0046] Further, the lower arm mounting part 30 is integrally formed at a first side toward a rear of the vehicle from a lower portion of the wheel bearing mounting part 10 and is fastened with a lower arm 31.

[0047] Here, the lower arm mounting part 30 is integrally formed with a ring-shaped mounting bush 33.

[0048] The mounting bush 33 may more smoothly mount the lower arm 31 when the lower arm mounting part 30 is mounted with the lower arm 31.

[0049] According to the exemplary embodiment of the present invention, the flat reinforcing part 40 extends from the wheel bearing mounting part 10 toward a front of the vehicle.

[0050] Here, as illustrated in FIG. 3, the flat reinforcing part 40 connects between the wheel bearing mounting part 10 and the trailing arm mounting part 50.

[0051] Further, the flat reinforcing part 40 may be formed to have a thicker thickness from the trailing arm mounting part 50 toward the wheel bearing mounting part 10.

[0052] That is, the flat reinforcing part 40 is formed in a same width length as a thickness of the wheel bearing mounting part 10. The flat reinforcing part 40 may be formed to be inclined upward from the trailing arm mounting part 50 toward the wheel bearing mounting part 10.

[0053] According to the exemplary embodiment of the present invention, the trailing arm mounting part 50 is integrally connected with the flat reinforcing part 40 and is fastened with a trailing arm 51.

[0054] Further, the assist arm mounting part 60 is integrally formed at the lower portion of the flat reinforcing part 40 and is fastened with an assist arm 61.

[0055] In the instant case, the assist arm mounting part 60 is formed in a fork shape so that the assist arm bush unit 63 mounted at the assist arm 61 is mounted, like the upper arm mounting part 20.

[0056] That is, the assist arm mounting part 60 includes two flanges that are formed at a first side and a second side with respect to the front and rear direction of the vehicle. The assist arm bush units 63 are inserted between the respective flanges and are bolt-fastened with each other.

[0057] The assist arm mounting part 60 may be formed to correspond to a tip portion of the flat reinforcing part 40 that is positioned toward a front of the vehicle.

[0058] Meanwhile, the exemplary embodiment of the present invention describes as an example that the assist arm mounting part 60 is formed to correspond to the tip portion of the flat reinforcing part 40 but is not limited thereto and therefore the position of the assist arm mounting part 60 may be changed and applied depending on the mounting position of the assist arm 61.

[0059] Therefore, the carrier 1 for a suspension system of vehicle according to the exemplary embodiment of the present invention applies the flat reinforcing part 40 between the trailing arm mounting parts 50 extending from the wheel bearing mounting part 10 where the wheel bearing is mounted toward a front of the vehicle, improving the stiffness at the connected portions between the respective arms.

[0060] Meanwhile, the carrier 1 for a suspension system of vehicle according to the exemplary embodiment of the present invention describes as an example in which the wheel bearing mounting part 10, the trailing arm mounting part 50, and the assist arm mounting part 60 are connected to each other through the flat reinforcing part 40 to improve the stiffness of the connected part but is not limited thereto and therefore the respective arm mounting parts including the assist arm mounting part 60 may have a connection structure through the flat reinforcing part 40.

[0061] For convenience in explanation and accurate definition in the appended claims, the terms upper, lower, inner, outer, up, down, upper, lower, upwards, downwards, front, rear, back, inside, outside, inwardly, outwardly, interior, exterior, inner, outer, forwards, and backwards are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures.

[0062] The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and their practical application, to thereby enable others skilled in the art to make and utilize various exemplary embodiments of the present invention, as well as various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents.
