Definitions
- the present invention relates to a chassis frame provided with a connection member made of a metal pipe connected to a vehicle body frame.
- the chassis frame is required to be as light as possible while requiring high strength and rigidity. From this, for example, as seen in Patent Document 1, a cross structure and side members made of metal pipes are assembled in a cross beam shape, and a hollow structure is formed by combining an upper die and a lower die obtained by pressing a metal plate in the middle. Is done.
- Such a chassis frame is connected to the vehicle body frame by using a cross member, a side member, or an attachment arm made of a metal pipe separately provided on the upper die or the lower side as a connecting member, and bolting the connecting member.
- the chassis frame disclosed in Patent Document 1 includes a flat mounting surface at the center of the left and right of the laminated portion in which the end portion of the side member is crushed into a substantially gate-shaped cross section and the pipe surfaces (pipe peripheral surfaces) are overlapped.
- a mounting portion composed of vertical ribs bent from the surface toward the left and right sides of the laminated portion is provided at the end portion (Patent Documents 1 and [0006] [0008]).
- the mounting surface has a bolt hole at the center, and is bolted to the mounting portion of the corresponding body frame.
- the vertical rib increases the rigidity at the end of the side member, or restricts the width of the mounting surface to eliminate interference with other members (Patent Document 1, [0009]).
- the chassis frame disclosed in Patent Document 1 is formed with a through-hole that swells the folded edge of the laminated portion of the vertical ribs and communicates the inside and outside of the connecting member (see Patent Document 1 and FIG. 2).
- the through hole can be used as a discharge hole for the rust preventive paint poured into the chassis frame.
- the discharge hole cannot be made large in cross section, but tends to be long, and there is a problem that the discharge speed of the anticorrosive paint is slow.
- the pipe constituting the connecting member is limited in size, it is difficult to increase the cross-sectional shape of the through hole. Therefore, in addition to increasing the cross-sectional shape, the authors studied to increase the discharge speed of the rust preventive paint so that the through hole can be used more actively as the discharge hole of the rust preventive paint.
- a chassis frame with a metal pipe connection member that was connected to the body frame.
- a mounting portion composed of a flat mounting surface at the center of the left and right sides and a vertical rib bent from the mounting surface toward the left and right sides of the laminated portion is provided at the end, and the vertical rib has a folded edge of the laminated portion.
- a through-hole is formed which is inflated to communicate the inside and outside of the connection member, and the pipe surface surrounding the opening of the through-hole is cut away to shorten the through-hole.
- the connecting member varies depending on the chassis frame, but as described above, the cross member or side member of the chassis frame in which the cross member and side members made of metal pipe are assembled in a cross-beam shape, or the metal plate is pressed.
- the chassis frame in which the upper mold and the lower mold are combined in the middle is a mounting arm made of a pipe separately provided on the upper mold or the lower mold.
- “shortening the through-hole” means that the substantial length of the through-hole extending in the same cross section is shorter than when the pipe surface surrounding the opening of the through-hole is not cut.
- the opening of the through hole becomes three-dimensional depending on the shape of the cut end surface, and the length of the through hole varies depending on the opening portion. In this case, the longest length should just be shorter than the original through-hole.
- the pipe surface surrounding the opening is cut to shorten the through hole so that the through hole of the vertical rib that can be used as the discharge hole for the anticorrosive paint is shortened.
- the through-hole is shortened.
- the vertical rib is preferably cut out on the pipe surface surrounding the opening of the through hole outside a virtual circle that is concentric with the bolt hole provided on the mounting surface and is larger than the size of the bolt head passing through the bolt hole.
- the through-hole provided in the reinforcing vertical rib is made as short as possible among the attachment portions provided at the end of the connection member connected to the vehicle body frame, and the paint ( Increase the discharge speed of rust preventive paint.
- being able to increase the discharge speed of rust preventive paint means that the resistance to inflow and outflow of air is reduced to a small extent, and smooth inflow and outflow of air when rust preventive paint is poured into the chassis frame. The effect to do.
- the present invention shortens the work time for applying the anticorrosive paint to the inside of the chassis frame and contributes to the improvement of the production efficiency by shortening the manufacturing time as a whole.
- FIG. 6 is a plan view corresponding to FIG.
- FIG. 6 is a plan view corresponding to FIG.
- FIG. 6 is a plan view corresponding to FIG.
- the present invention is a metal pipe mounting arm separately provided on the upper mold 11 of a chassis frame 1 in which an upper mold 11 and a lower mold 12 formed by pressing a metal plate are joined together.
- (Connecting member) 13 is applied.
- the mounting arm 13 of this example is a metal pipe connecting member provided on the left and right edges of the upper mold 11 of the chassis frame 1 and protrudes upward, then bends horizontally to the left or right and ends.
- the attachment part 2 is provided in the part.
- the mounting portion 2 includes a flat mounting surface 21 at the center of the left and right of the laminated portion in which the end portions are crushed into a substantially gate-shaped cross section and the pipe surfaces are stacked, and the mounting surface It is comprised from the vertical ribs 22 and 22 bent toward the left and right both sides of the laminated part from 21.
- the vertical rib 22 has a teardrop shape in which the folded edge of the laminated portion is inflated, and the pipe surface is not in close contact with each other. Therefore, the vertical rib 22 forms a through hole 221 that communicates the inside and outside of the connection member.
- the through-hole 221 has a teardrop shape in front view following the outer shape of the vertical rib 22, but is slightly elongated because the pipe surface surrounding the opening of the through-hole 221 is cut out.
- the pipe surface surrounding the opening of the through hole 221 is concentric with the bolt hole 211 provided in the mounting surface 21 and is larger than the size of the bolt head passing through the bolt hole 211.
- a pair of left and right oblique end surfaces 23, 23 are formed by cutting symmetrically along the tangent line of the circle Cb.
- the pipe surface is cut symmetrically along the tangent of the virtual circle Cb inclined about 20 degrees from the end face before cutting, and the length Ls of the shortened left and right through holes is determined by the original length of the through hole.
- the length is about half of Lo.
- the present invention can also be configured as follows.
- the pipe surface surrounding the opening of the through hole 221 is concentric with the bolt hole 211 provided in the mounting surface 21 and is larger than the size of the bolt head passing through the bolt hole 211.
- a pair of left and right cut end surfaces 24, 24 are formed by cutting out symmetrically along the circumference of the virtual circle Cb and a line segment intersecting the virtual circle Cb. The cut end face 24 makes it easier to shorten the length of the through hole 221 than to form the oblique end face 23.
- the present invention may be applied only to either the left or right through hole 221.
- the second example is such that the pipe surface surrounding the opening of the through hole 221 is concentric with the bolt hole 211 provided in the mounting surface 21 and is larger than the size of the bolt head passing through the bolt hole 211. Only the right side is cut along the tangent line of the virtual circle Cb, and the oblique end face 23 is formed asymmetrically in the left-right direction. The obliquely end surface 23 may be formed by cutting away only the left side of the pipe surface surrounding the opening of the through hole 221.
- another example 3 is that the pipe surface surrounding the opening of the through hole 221 is concentric with the bolt hole 211 provided in the mounting surface 21 and is passed through the bolt hole 211. Only the right side is cut out along the circumference of the above-mentioned virtual circle Cb and the line segment intersecting the virtual circle Cb, and the cut-out end face 24 is formed asymmetrically in the left-right direction.
- the notch end surface 24 may be formed by asymmetrically cutting the pipe surface surrounding the opening of the through hole 221 only on the left side.
- Chassis frame 11 Upper mold 12 Lower mold 13 Mounting arm (connection member) 2 Mounting part 21 Mounting surface 211 Bolt hole 22 Vertical rib 221 Through hole 23 Diagonal end face 24 Notch end face Lo Original length of through hole Ls Shortened through hole length Cb Virtual circle concentric with bolt hole
