Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle shock absorber mounting structure.

[0002]

[Prior Art]

 Conventionally, as an example of a vehicle shock absorber mounting structure, there is one as shown in FIGS. A vertical plate portion 62 on the passenger compartment side of the wheel house inner panel 60 has a substantially flat plate shape, and a bracket 65 provided inside thereof has a shock absorber (hereinafter, simply referred to as an absorber) forming a part of a suspension mechanism. ) 64 is attached. The lower portion of the wheel house inner panel 60 and the floor panel 66 are joined together, and a reinforcing member 68 is provided over the lower portion of the wheel house inner panel 60, the floor panel 66, and the floor side member 67.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional structure, the wheel house inner panel 60 needs to be provided with an appropriate gap between the absorber 64 and the tire (not shown). Therefore, the absorber 64 in the vertical plate portion 62 of the wheel house inner panel 60 is required. In a portion other than the portion where is provided, an excessive gap is generated between the tire and the tire, and the vehicle compartment is narrowed accordingly. Further, since the bracket 65 and the reinforcing member 68 are formed separately, the number of component parts increases and the structure becomes complicated. The impact load input from the tire side to the bracket 65 via the absorber 64 is first transmitted to the wheel house inner panel 60 entirely and then to the floor panel 66, the reinforcing member 68 and the side member 67. It will be. For this reason, it is necessary to increase the plate thickness of the wheel house inner panel 60 so that the wheel house inner panel 60 has sufficient strength to withstand the impact load. Get higher

In view of the above-mentioned conventional problems, the object of the present invention is not only to make the vehicle compartment unnecessarily narrow and to reduce the number of components, but also to dismount the bracket from the wheel house inner panel. A shock absorber mounting structure for a vehicle, in which a shock load transmitted to a vehicle is reduced.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a shock absorber mounting structure in which a shock absorber forming a part of a suspension mechanism is attached to a bracket provided on a wheel house inner panel, and the shock absorber is surrounded by the shock absorber. In this way, the bracket is provided so as to project from the general surface of the wheel house inner panel toward the passenger compartment, the shock absorber is attached to the absorber mounting portion on the upper portion of the bracket, and the lower portion of the bracket is extended to the floor side member. It is integrally connected to the floor side member.

[0006]

[Action]

 In the vehicle shock absorber mounting structure configured as described above, the bracket is provided so as to surround the absorber so as to project from the general surface of the wheel house inner panel to the passenger compartment side, thereby providing the general surface of the wheel house inner panel. Since the gap between the tire and the tire does not need to be made larger than necessary, the space inside the vehicle compartment is expanded accordingly. Further, since the lower part of the bracket is extended to the floor side member and coupled, it is not necessary to provide a reinforcing member separate from the bracket unlike the conventional case. The impact load input from the tire to the bracket through the absorber is dispersed and transmitted to the wheel house inner panel and floor side member.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 4, the wheel house 10 is formed by combining a wheel house outer panel 14 and a wheel house inner panel 12 at the upper part (shown in a simplified manner in FIG. 1), and the wheel house outer panel 14 is used for the vehicle. It is connected to the side panel 16 of the body.

The vertical plate portion 18 on the vehicle interior side of the wheel house inner panel 12 is provided at a position where an appropriate gap is provided between the wheel house inner panel 12 and a tire (not shown). As shown in FIG. 1, a vertically long rectangular cutout 20 is formed in the center of the vertical plate portion 18 on the vehicle interior side of the wheel house inner panel 12, and a bracket 22 is formed in the cutout 20. Are combined.

The bracket 22 has a hat-shaped cross section that surrounds the absorber 30, and as shown in FIGS. 1, 3, and 4, is closer to the passenger compartment than the general surface formed by the vertical plate portion 18 of the wheel house inner panel 12. Overhangs. As shown in FIG. 4, an absorber attachment portion 26 is formed on the upper portion of the bracket 22. Then, as shown in FIGS. 1 and 2, the flanges 28 on both sides of the bracket 22 and the flanges 29 at the ends of the absorber mounting portion 26 are provided on the inner surface of the vertical plate portion 18 of the wheel house inner panel 12 through the notches 20. Joined by welding.

As shown in FIGS. 1 and 4, the lower portion of the bracket 22 is extended to a floor side member 50, and a horizontal flange 42 is formed at the tip of the extension portion 40. At, the lower surface of the floor side member 50 is joined by welding.

As shown in FIG. 4, the absorber 30 forming a part of the suspension has a well-known structure, and absorbs vibration transmitted from the ground to the vehicle body through the tires. Then, a mounting shaft 32 on the upper portion of the absorber 30 is inserted into a mounting hole (not shown) of the absorber mounting portion 26, and is fixed by a nut 37 with a spacer 34, a washer 35 and a rubber mounting 36 interposed. A cap 38 is fitted on the nut 37. The lower end of the absorber 30 is fixed to a hub (not shown).

A cutout portion 46 is formed on the floor panel 44 corresponding to the wheel house inner panel 12 and the bracket 22, and a vertical flange 48 is formed on an edge portion of the cutout portion 46, and the flange 48 is formed. It is connected to the lower part of the inner panel 12 and the lower part of the bracket 22. A floor side member 50 having a hat-shaped cross section is provided on the lower surface of the floor panel 44.

The present embodiment is configured as described above. Accordingly, since the bracket 22 projects toward the vehicle compartment side from the general surface formed by the vertical plate portion 18 of the wheel house inner panel 12 so as to surround the absorber 30, the vertical plate portion 18 of the wheel house inner panel 12 is generally formed. The gap between the surface and the tire does not become larger than necessary, and the vertical plate portion 18 is located outside the vehicle accordingly. Therefore, the space in the vehicle compartment is expanded accordingly, and the expanded space S can be used as a tool storage space or the like.

Further, it is no longer necessary to provide a reinforcing member separate from the bracket 22 in the related art, the number of constituent parts is reduced accordingly, and the structure is simplified.

In addition, the impact load input from the tire to the bracket 22 via the absorber 30 is dispersed and transmitted to the wheel house inner panel 12 and the floor side member 50. Since the applied load is reduced, the necessity of increasing the plate thickness of the wheel house inner panel 12 to increase its strength is eliminated.

Further, since the bracket 22 projects from the wheel house inner panel 12 toward the passenger compartment, the seat belt anchor A can be attached to the bracket 22 as shown in FIG. 1, which is convenient.

[0017]

[Effect of the device]

 As described above, according to the present invention, the space between the general surface of the wheel house inner panel and the tire does not need to be unnecessarily large, and the space in the vehicle interior is expanded accordingly, so that it is expanded. The space can be used as a tool storage space. Further, unlike the conventional case, since it is not necessary to provide a reinforcing member separate from the bracket, the number of constituent parts can be reduced and the structure can be simplified. Further, since the impact load input from the tire to the bracket via the absorber can be dispersed and transmitted to the wheel house inner panel and the floor side member, the load applied to the wheel house inner panel can be reduced. As a result, it is possible to eliminate the need to increase the plate thickness of the wheel house inner panel to increase the strength.
