Description

Sub frame mounting bracket of vehicle's frame}

The present invention relates to a subframe mounting bracket of a vehicle body frame to remove a flow during the operation of the rotation axis by adding a pipe nut and a pipe nut reinforcement plate to the rotation shaft connecting the sub frame constituting the vehicle body frame.

The pipe nut 4 is fitted to the mounting bolt 3 which penetrates the upper part of the gusset 2 and is exposed to the upper part.

Fixing bracket (5) used for fixing the pipe nut (4) is formed in a 'b' shape, the joint surface (5 ') is joined to both ends by spot welding on the gusset (Gusset) surface is bent Is formed.

After the pipe nut (4) is fixed to the mounting bolt (3), the 'b' shaped fixing bracket (5) is inserted into the mounting bolt (3), and the joint surface (5 ') of the bracket (5), respectively, welding fixed Let's do it.

3 is a perspective view showing the assembled state of the sub-frame mounting bracket, and shows the assembled state of the above structure.

Since the respective components are manufactured separately when the sub-frame mount is assembled, the fixing positions of the holes and the brackets of the sub-frames through which the mounting bolt penetrates are changed. In this case, if the defective product is not selected and used for vehicle assembly, the assembly frame of the completed subframe structure is degraded because the subframe fixing bracket for fixing the mounting bolt and the pipe nut installed on the subframe does not adhere closely to the gusset. there was.

The present invention has been made to solve the above problems, and when the sub-frame is fixed in addition to the auxiliary mounting brackets are additionally installed, the mounting strength of the sub-frame is assembled even if the fixing position of the mounting bolt, pipe nut and the fixing bracket is wrong. It is an object of the present invention to provide a subframe mounting bracket to prevent deterioration.

In order to achieve the above object, the bracket of the present invention, the sub-frame mounting, in the sub-frame assembly, the first bracket is formed in the 'b' shape and the upper surface is formed with a hole in which the support wall is vertically formed, 'c' shape And a hole having a support wall vertically formed on an upper surface thereof, and configured to include a second bracket installed below the first bracket.

Figure 4 is a perspective view showing the assembly state using the bracket of the sub-frame mounting according to the present invention, Figure 5 is a cross-sectional view of the line B-B 'of Figure 4, the bracket of the sub-frame mounting, is formed in the' b 'shape A first bracket 10 having a first hole 14 provided with a first support wall 16 vertically on an upper surface thereof is formed in a 'c' shape, and a second support wall 26 perpendicular to an upper surface thereof. The installed second hole 24 is formed so that it can be fitted into the second bracket 20, which is installed on the lower portion of the first bracket 10, the first hole 14 of the first bracket 10. It shows that the support 32 is composed of a pipe nut 30 formed.

Looking at the configuration of the present invention in detail as follows.

The first bracket 10 is formed to be bent in a 'b' shape, and the joining surfaces 12 are bent to form both ends thereof so that they can be joined to the gusset by spot welding. The first hole 14 is formed so that the support portion 32 of the first hole 14 can be fitted, and the first support wall 16 is formed on the circumferential surface of the first hole 14 perpendicular to the bracket surface. When the support part 32 is fitted into the first hole 14, a certain amount of free space may be allowed.

The second bracket 20 is bent in a 'c' shape, and the joining surfaces 22 are bent at both ends to be joined to the gusset by spot welding. In addition, a second hole 24 having a size to which the support 32 of the pipe nut 30 is fitted is formed at the center of the second bracket 20, and the circumference of the second hole 24 is formed. On the surface is formed a second support wall 26 formed perpendicular to the surface of the bracket. When the pipe nut 30 is fitted into the second hole 24, a certain amount of free space may be allowed.

The upper part of the pipe nut 30 has a diameter smaller than the diameter of the pipe nut 30, but the support 32 is formed to be sized to fit into the first hole (14).

After contacting the subframe 1 to the lower part of the gusset (2), the mounting bolt (3) in the lower side through the sub-frame (1) and gusset (2) to be fixed. Fit the pipe nut (4) to the mounting bolt (3) exposed to the top of the gusset (2). By fitting the pipe nut 4 the exposed part of the mounting bolt 3 is completely covered.

After the pipe nut 4 is fixed, the second bracket 20 is inserted into the pipe nut 4 and the joint surfaces 22 at both ends of the second bracket 20 are spot welded to the gusset 2 surface. Let's do it.

After the second bracket 20 is fixed, the first hole 14 of the first bracket 10 is fitted into the pipe nut 4 to fix the joint surface of the both ends of the first bracket 10. Weld by spot welding on and fix it completely.

The present invention configured as described above, by fixing the sub-frame to the gusset using the mounting bolts and to join the bracket further configured by the bracket, even if the assembly unevenness caused by the manufacturing tolerances of the components by the added bracket It has the effect of maintaining a constant assembly strength.
