Description

Technical Field

[0001] The present invention relates to a suspension support structure for a vehicle that supports an input load from a shock absorber (buffer device) or the like. Background Art

[0002] A suspension support (shock absorber housing, suspension tower) is provided on the body side of an automobile or the like, and the suspension support (shock absorber housing) supports an input load from a suspension device composed of a shock absorber, a coil spring, and the like.

[0003] As is well known, the suspension support is provided adjacent to the wheel housing and protrudes into the engine compartment (motor room). Various wire harnesses are often laid along the suspension support in the engine compartment, and the wire harnesses are supported by the suspension support. For example, Patent Document 1 discloses a wire harness laying structure in which a bracket is fixed to the side wall portion of the suspension support, and the wire harness is supported by the suspension support via the bracket.

[0006] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2019-055686. Summary of the Invention

[0007] Technical Problem to be Solved by the Invention

[0008] When a wire harness is supported by a suspension support via a bracket, the following structure is adopted: a mounting portion of the bracket is formed on the suspension support, and the bracket is fastened to the mounting portion by bolts and nuts. Since the mounting portion is formed by bending (bulging) a part of the suspension support, when a load is input from the shock absorber, stress is likely to concentrate on the mounting portion structurally. Although such a structure generally does not immediately affect the body strength, it is one of the main reasons for the reduction of the rigidity of the suspension support. Therefore, if an excessive load is repeatedly input from the suspension device, the suspension support may be deformed or the like. In particular, for a vehicle with a wider area below the waistline and equipped with wheels having a relatively large size (diameter), the length of the suspension support in the vertical direction and the length in the front-rear direction tend to become longer. Therefore, from the viewpoint of preventing the above deformation or the like, it is important to ensure the rigidity of the suspension support. In addition, the same applies to the case where a member other than the wire harness is supported by the suspension support via a bracket.

[0009] To eliminate such an inappropriate situation, the suspension support can also be strengthened by a reinforcing member (for example, Japanese Unexamined Patent Application Publication No. 2009-35059), but this is accompanied by an increase in weight and cost due to an increase in the number of components, and thus is not necessarily preferable.

[0010] In view of the above situation, an object of the present invention is to provide a technology that can ensure the rigidity of a suspension support in a structure where components such as a wire harness are supported by a suspension support via a bracket through a reasonable structure.

[0011] Technical means for solving technical problems

[0012] The suspension support structure of a vehicle according to one aspect of the present invention is characterized by including: a suspension support formed on the side part in the front compartment of the vehicle body and supporting a shock absorber; a bracket for mounting components to be fixed to the above suspension support; wherein, the suspension support includes: a curved side wall portion that is joined to the front side of the vehicle body and extends upward; a top portion disposed at the upper end portion of the side wall portion and supporting the upper end portion of the shock absorber; wherein, paired mounting portions for the bracket are formed on the side wall portion, the paired mounting portions including portions that bulge inward in the vehicle width direction; the paired mounting portions have mounting surfaces for the bracket, and at least each mounting surface sandwiches a line formed by the intersection of a plane parallel to the central axis of the shock absorber extending in the vehicle width direction and the side wall portion, and is located on different sides in the vehicle front-rear direction; the bracket is disposed across the line and fixed to the paired mounting portions.

[0013] The above suspension support structure can ensure the rigidity of the suspension support through a reasonable structure. That is, due to the load input from the shock absorber, mainly vertical forces (loads) act on the area of the suspension support along the line (imaginary line) formed by the intersection of a plane parallel to the vehicle width direction, that is, a plane including the central axis of the shock absorber, and the side wall portion. In the above suspension support structure, the paired mounting portions for the bracket are set such that at least their respective mounting surfaces sandwich the line and are located on different sides in the vehicle front-rear direction. That is, each mounting portion is a portion that does not exist on the line, or a portion with a very small amount of bulge on the line (a portion with a very small amount of change in the side wall portion). Thereby, stress concentration on the mounting portion is suppressed or avoided, and a reduction in the rigidity of the suspension support due to the mounting portion is suppressed.

[0014] Moreover, since the bracket is fixed to the side wall portion (mounting portion) of the suspension support in a manner that straddles the line, the bracket itself functions as a reinforcing member of the suspension support, suppressing the relative displacement of the areas on both sides of the line in the side wall portion.

[0015] Therefore, when components such as a wire harness are supported by the suspension support via the bracket, the rigidity of the suspension support can be reasonably ensured without separately providing a dedicated reinforcing member.

[0016] Preferably, in the above suspension support structure, the paired mounting portions are offset in the vertical direction.

[0017] This structure suppresses the deformation of the regions on the front and rear sides of the line sandwiched by the side wall portions in a mutually twisted manner. Therefore, the rigidity of the suspension support is ensured more effectively.

[0018] Preferably, in the above suspension support structure, the cross-section from the upper part of the side wall portion to the top portion is formed in a curved shape at least along the line.

[0019] In this structure, since there is no ridge line portion formed in the part from the upper part to the top of the side wall portion, stress concentration is difficult to occur in this part. Therefore, the rigidity of the suspension support is ensured more effectively.

[0020] Preferably, in the above suspension support structure, the bracket has a ridge line portion, and the ridge line portion extends in a manner intersecting the line segment between the fixed positions of the pair of mounting portions to which it is connected and fixed.

[0021] This structure suppresses the deformation of the front and rear side wall portions in a manner of being twisted with the line sandwiched therebetween. Therefore, the rigidity of the suspension support is ensured more effectively.

[0022] At this time, the bracket includes: a reference surface portion along the side wall portion; a pair of fixing portions respectively bulging from the above reference surface portion toward the suspension support side; a component assembly portion extending from the reference surface portion to the opposite side of the suspension support, wherein the fixing portion includes: a fixing surface portion which is the inner bottom surface and is fixed to the mounting portion; a connecting surface portion connecting the reference surface portion and the fixing surface portion, and the boundary portions of the reference surface portion and the fixing surface portion with the connecting surface portion respectively have the ridge line portion.

[0023] In this structure, the fixing surface portion of the bracket fixed to the suspension support (mounting portion) is offset toward the suspension support side, so that the bulging amount of the mounting portion can be suppressed accordingly. That is, even when it is necessary to separate the components assembled to the bracket from the suspension support by a certain distance, the bulging amount on the mounting portion side can be suppressed. Therefore, compared with the case where the bulging amount is large, the stress concentration at the mounting portion can be reduced, and the rigidity of the suspension support can be effectively ensured. And in the bracket, the boundary portions of the reference surface portion and the fixing surface portion with the connecting surface portion are provided with ridge line portions, so that the above-mentioned effects generated by the ridge line portions can also be enjoyed together.

[0024] At this time, preferably, the component assembly portion is located between the pair of fixing portions in the vehicle front-rear direction.

[0025] In the above suspension support structure, the bracket functions as a reinforcing member of the suspension support (side surface portion). Therefore, the above structure in which the component assembly portion is arranged between the pair of fixing portions of the bracket makes the position stability of the assembled components good.

[0026] Advantages of the Invention

[0027] When the suspension support structure of the vehicle involved in each of the above forms supports components such as wire harnesses through the suspension support, the rigidity of the suspension support can be ensured through a reasonable structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0037] Figure 1 is a perspective view of the engine compartment 1 of a vehicle (automobile), mainly showing the right side within the engine compartment 1. In the present embodiment, the engine compartment 1 is an example of the front compartment provided in the vehicle (body). However, it is not limited thereto. When the engine of the automobile is arranged under the floor or at the rear of the vehicle body, etc., outside the front part of the vehicle body, or when the vehicle is an EV vehicle without an engine, the front compartment is the "front side section" in front of the cockpit in the vehicle body.

[0038] The vehicle body shown in the figure includes the following: a bulkhead 2 that separates the engine compartment 1 from the passenger compartment outside the figure; a pair of left and right suspension towers 6 that project into the engine compartment 1; and a cowl panel 4 that is disposed above the bulkhead 2 and extends in the vehicle width direction (left - right direction). Fr, Re, Le, and Ri in the figure represent the front, rear, left, and right directions of the vehicle body respectively.

[0039] The rear ends of a pair of left and right front side frames 8 are joined to the lower end of the front side of the bulkhead 2. A pair of left and right wheel skirt reinforcements 10 (hereinafter simply referred to as skirt reinforcements 10) that extend in the front - rear direction are respectively disposed at the left and right ends of the engine compartment 1, forming the left and right side walls of the engine compartment 1. The above - mentioned pair of skirt reinforcements 10 are respectively connected to the middle parts of the front side frames 8 disposed below via connecting frames 12. The front side frames 8, skirt reinforcements 10, and connecting frames 12 cooperate to support the suspension towers 6 on the vehicle body.

[0040] A wiring harness is disposed along the cowl panel 4, suspension towers 6, and connecting frames 12. When the vehicle is a hybrid vehicle, the wiring harness 16 includes a wiring harness for connecting the battery and the inverter, etc. A bracket 14 is fixed to the suspension tower 6, and a part (the middle part) of the wiring harness 16 is supported by the suspension tower 6 via this bracket 14.

[0041] Figure 2 It is an oblique view of the engine compartment 1 in the state where the wiring harness 16 is removed. Figure 3 and Figure 4 It is a view of the suspension tower 6 seen from the left side within the engine compartment 1. Additionally, Figure 3 shows the state where the bracket 14 is fixed. Figure 4 shows the state where the bracket 14 is removed.

[0042] The suspension tower 6 is formed to project inward in the vehicle width direction (inside the engine compartment 1) from the skirt reinforcement 10. The suspension tower 6 includes a curved side wall portion 20 and a top portion 22. Both the side wall portion 20 and the top portion 22 include press - formed parts made of steel plates, and they are integrally joined by welding to form the suspension tower 6.

[0043] The side wall portion 20 is integrally formed by the following parts: a partially cylindrical bending portion 20a which is bent such that its upper part has an axis slightly inclined backward with respect to the vertical direction; a front flange portion 20b which extends forward from the front end portion of the bending portion 20a and extends upward more toward the right side; and a rear flange portion 20c which extends backward from the rear end portion of the bending portion 20a. "Partially cylindrical" means a bending shape in which the cross-sectional shape forms a part of a cylinder. In the side wall portion 20, the front flange portion 20b is joined to the rear end side portion of the connecting frame 12. In addition, the upper half of the rear flange portion 20c is joined to the side wall portion of the apron reinforcement 10, and the lower half is joined to the upper portion of a wheel housing (not shown).

[0044] The top portion 22 is configured to block the upper end portion of the bending portion 20a formed as a partially cylinder. The top portion 22 includes: a dome-shaped shock absorber base portion 22a with a substantially flat upper end; and a flange portion 22b which extends rightward from the right end portion of the shock absorber base portion 22a and extends in the front-rear direction. In the top portion 22, the peripheral portion (base portion) of the shock absorber base portion 22a is disposed inside the side wall portion 20 and integrally joined to the side wall portion 20. In addition, the flange portion 22b is joined to the apron reinforcement 10.

[0045] Figure 5 and Figure 6 is a cross-sectional view of the suspension support 6, Figure 5 is a cross-sectional view along Figure 4 the V-V line of Figure 6 is a cross-sectional view along Figure 4 the VI-VI line of

[0046] As Figures 4 to 6 shown by the phantom line in, a shock absorber 50 (buffer device) and a coil spring 52 are disposed inside the suspension support 6. The shock absorber 50 and the coil spring 52 together with a lower arm (not shown) outside the figure constitute a front suspension device, which has a function of absorbing shocks caused by road surface irregularities during vehicle travel and reducing vehicle body vibration. The front suspension device mounted on this example vehicle is, for example, a strut suspension device in which the shock absorber 50 and the coil spring 52 are integrated.

[0047] A spring seat 50a for supporting the coil spring 52 is joined to the upper end portion of the shock absorber 50. The spring seat 50a abuts against the top portion 22 (shock absorber base portion 22a) of the suspension support 6 from below via a rubber mounting member and is fastened to the shock absorber base portion 22a by bolts and nuts. Thus, the shock absorber 50 is assembled to the suspension support 6 (shock absorber base portion 22a). That is, the shock absorber 50 is supported by the suspension support 6.

[0048] The shock absorber 50 supported by the suspension support 6 is inclined such that its upper part is slightly inclined backward with respect to the vertical direction. Figure 3 andFigure 4 The line L1 indicated by the one-dot chain line in [Fig. 0] represents an imaginary line formed by the intersection of a plane parallel to the central axis of the shock absorber 50 extending in the vehicle width direction and the suspension support 6. Therefore, this line L1 can be regarded as the central axis of the shock absorber 50 in [Fig. 0] and [Fig. 1] as well. Figure 3 and Figure 4 in [Fig. 1] as well.

[0049] As Figures 2 to 4 shown in [Fig. 2], in the side wall portion 20 of the suspension support 6, front and rear pairs of mounting portions 24, 26 for mounting the bracket are formed in the bent portion 20a, and the bracket 14 is fixed to the mounting portions 24, 26.

[0050] Both the mounting portions 24, 26 include raised portions formed in the bent portion 20a. The front mounting portion 24 (referred to as the front mounting portion 24 for simplicity) and the rear mounting portion 26 (referred to as the rear mounting portion 26 for simplicity) are provided on different sides sandwiching the line L1. In addition, the rear mounting portion 26 is slightly offset downward with respect to the front mounting portion 24. As will be described later, such a configuration of the mounting portions 24, 26 effectively ensures the rigidity of the suspension support 6.

[0051] As Figure 4 and Figure 6 shown in [Fig. 3] and [Fig. 4], the mounting portions 24, 26 are of a substantially frustum shape with flat mounting surfaces 24a, 26a at the top, and the respective mounting surfaces 24a, 26a are substantially in the same plane. Mounting bolts B ( Figure 4 omitted in [Fig. 4]) including welding bolts project perpendicularly to the respective mounting surfaces 24a, 26a from the mounting surfaces 24a, 26a.

[0052] Figure 7 [Fig. 5] shows the bracket 14, where (a) is an oblique view ( Figure 2 a partial enlarged view of [Fig. 5]) in the state of being fixed to the suspension support 6, (b) is a front view, and (c) is a side view, respectively showing each bracket 14.

[0053] The bracket 14 is a press-formed part of sheet metal. The bracket 14 includes: a flat base surface portion 30 (corresponding to the "reference surface portion" of the present invention); fixing portions 34, 36 provided at the front and rear ends of the base surface portion 30; a first component assembly portion 32 provided at the lower end portion of the base surface portion 30; and a second component mounting portion 38 provided at the upper end portion of the base surface portion 30.

[0054] The fixing portions 34, 36 are the parts of the bracket 14 fixed to the suspension support 6 (bent portion 20a). The front fixing portion 34 (referred to as the front fixing portion 34 for simplicity) is fixed to the front mounting portion 24 of the suspension support 6, and the rear fixing portion 36 (referred to as the rear fixing portion 36 for simplicity) is fixed to the rear mounting portion 26 of the suspension support 6.

[0055] The fixing portions 34 and 36 are formed, for example, by drawing so as to bulge from the base surface portion 30 toward the suspension support 6 (side wall portion 20) side. Thus, the front fixing portion 34 has a flat fixing surface portion 34a offset from the base surface portion 30 toward the suspension support 6 side and a connecting surface portion 34b connecting the fixing surface portion 34a to the base surface portion 30. Moreover, a ridge line portion 341 is provided at the boundary between the connecting surface portion 34b and the base surface portion 30, and a ridge line portion 342 is provided at the boundary between the connecting surface portion 34b and the fixing surface portion 34a. A fixing hole 35 corresponding to the mounting bolt B is formed in the fixing surface portion 34a.

[0056] The same applies to the rear fixing portion 36, which has a flat fixing surface portion 36a offset from the base surface portion 30 toward the suspension support 6 side and a connecting surface portion 36b connecting the fixing surface portion 36a to the base surface portion 30. Moreover, a ridge line portion 361 is provided at the boundary between the connecting surface portion 36b and the base surface portion 30, and a ridge line portion 362 is provided at the boundary between the connecting surface portion 36b and the fixing surface portion 36a. A fixing hole 37 is formed in the fixing surface portion 36a.

[0057] The ridge line portions 341, 342, 361, and 362 formed in the fixing portions 34 and 36 are formed to cross the fixing positions where the connection bracket 14 is fixed to the mounting portions 24 and 26, and more specifically, to cross a line segment (straight line L2) at the center positions of the connection fixing holes 35 and 37.

[0058] As Figure 2 And Figure 3 shown, with the mounting bolt B passing through the fixing holes 35 and 37, the fixing portions 34 and 36 are overlapped with the mounting portions 24 and 26, and the nut N is screwed onto the mounting bolt B, whereby the bracket 14 is fastened to the suspension support 6 (side wall portion 20). Thus, the bracket 14 is fixed to the suspension support 6 in a state of straddling the two mounting portions 24 and 26.

[0059] The first component assembly portion 32 is provided between the two fixing portions 34 and 36 in the front-rear direction. The first component assembly portion 32 is formed in a thin rectangular shape extending from the base surface portion 30 toward the opposite side of the suspension support 6, and a mounting hole 32a for the wire harness 16 is formed near the front end thereof.

[0060] The second component mounting portion 38 includes: a mounting surface portion 38a offset from the base surface portion 30 toward the opposite side of the suspension support 6; and a connecting surface portion 38b connecting the mounting surface portion 38a to the base surface portion 30. The mounting surface portion 38a extends while bending toward the rear and the right. Mounting holes 39 for the wire harness 16 are formed near the front end, near the center, and near the rear end (near the right end) of the mounting surface portion 38a, respectively.

[0061] As Figure 1As shown, the component 16a for fixing wiring, which is installed in the middle part of the wiring harness 16, is fixed to the first component assembly part 32 by bolts and nuts through the mounting holes 32a, so that the wiring harness 16 is fixed to the first component assembly part 32. In addition, a part of the wiring harness 16 is placed on the fastener assembled on the mounting hole 39 of the second component mounting part 38, so that the wiring harness 16 is fixed to the second component mounting part 38. Thus, the wiring harness 16 is supported by the suspension support 6 via the bracket 14.

[0062] [Function and effect]

[0063] In the above vehicle, mounting parts 24 and 26 including raised parts are formed on the side wall part 20 of the suspension support 6, and the wiring harness 16 is supported by the suspension support 6 via the bracket 14 fixed to the mounting parts 24 and 26. In such a suspension support structure, without taking any countermeasures, when a load is input from the shock absorber to the suspension support, stress may concentrate on the mounting parts, reducing the rigidity of the suspension support.

[0064] In view of the above, in the suspension support structure of the embodiment, as described above, the mounting parts 24 and 26 are arranged on the front and rear sides on different sides with the line L1 interposed therebetween ( Figure 3 and Figure 4 ). As described above, this line L1 is a line (imaginary line) formed by the intersection of a plane parallel to the central axis of the shock absorber 50 extending in the vehicle width direction and the suspension support 6. The load input from the shock absorber 50 to the suspension support 6 mainly acts on the area along this line L1 in the side wall part 20. Therefore, the suspension support structure of the embodiment in which the mounting parts 24 and 26 are distributed on the front and rear sides of the line L1 avoids stress concentration on the mounting parts 24 and 26, and suppresses the reduction in the rigidity of the suspension support 6 due to this stress concentration. And the bracket 14 is fixed across the two mounting parts 24 and 26, so the bracket 14 itself functions as a reinforcing member of the suspension support 6, suppressing the relative displacement of the areas on both sides of the line L1 in the side wall part 20.

[0065] Therefore, according to the suspension support structure of the embodiment, in the structure in which the wiring harness 16 is supported by the suspension support 6 via the bracket 14, the rigidity of the suspension support 6 can be reasonably ensured without additionally providing a dedicated reinforcing member.

[0066] In addition, in the suspension support structure of the embodiment, the mounting parts 24 and 26 are offset in the vertical direction, so the deformation of the areas on the front and rear sides of the line L1 interposed in the side wall part 20 in a mutually twisted manner is suppressed. That is, for example, as Figure 8As shown by the arrows, in the front region of the line L1, the displacement of the upper part of the side wall portion 20 towards the left and the lower part towards the right is suppressed (solid arrows), and in the rear region of the line L1, the displacement of the side wall portion 20 in the opposite direction, with the upper part towards the right and the lower part towards the left, is suppressed (dashed arrows). Therefore, the suspension support structure of the above-described embodiment also ensures the rigidity of the suspension support 6 in this regard.

[0067] In addition, although not mentioned in the above description, as Figure 5 shown, the cross-section of the suspension support 6 in the region from the upper part of the side wall portion 20 to the top 22 (the region indicated by the symbol R), at least along the line L1, is formed in a curved shape. In such a structure, no ridge line portion is formed in the part from the upper part of the side wall portion 20 to the top 22, so it is difficult for stress concentration to occur in this part, and the deformation of the suspension support 6 caused by this stress concentration is suppressed. Therefore, the suspension support structure of the above-described embodiment also ensures the rigidity of the suspension support 6 in this regard.

[0068] Furthermore, for the bracket 14 of the above-described embodiment, the fixing surfaces 34a, 36a fixed to the suspension support 6 are offset towards the suspension support 6 side with respect to the base surface 30, so that the amount of bulge h1 of the mounting portions 24, 26 on the suspension support 6 (side wall portion 20) side can be correspondingly suppressed (refer to Figure 7 (c)). That is, when it is necessary to separate the wiring harness 16 from the suspension support 6 by a certain distance, the amount of bulge h1 on the mounting portions 24, 26 side can be suppressed to be small by offsetting the offset amount h2 of the fixing surfaces 34a, 36a. Therefore, compared with the case where the amount of bulge h1 of the mounting portion 24 is large, the deformation of the mounting portions 24, 26 caused by stress concentration can be suppressed. Therefore, it can be said that the suspension support structure of the above-described embodiment also ensures the rigidity of the suspension support 6 in this regard.

[0069] Moreover, the bracket 14 has ridge line portions 341, 342, 361, 362 that intersect with the line L2 connecting the fixing positions (the center positions of the fixing holes 35, 37) fixed to the mounting portions 24, 26 ( Figure 7 (b)). These ridge line portions 341, 342, 361, 362 suppress the torsional deformation of the side wall portion 20 (refer to the arrows in Figure 8 ), that is, as described above, suppress the deformation of the regions on the front and rear sides sandwiching the line L1 in a mutually twisted manner. Therefore, the suspension support structure of the embodiment also contributes to ensuring the rigidity of the suspension support 6 in this regard.

[0070] In addition, the first component assembly portion 32 in the above-described bracket 14 is located between the two fixing portions 34 and 36 in the vehicle front-rear direction. The first component assembly portion 32 is provided between the fixing portions 34 and 36 that are fixed to the suspension support 6 (side wall portion 20) of the bracket 14. Such a structure makes it difficult for the position of the first component assembly portion 32 to shift. Therefore, it also has the advantage of improving the position stability of the wire harness 16 supported by the first component assembly portion 32.

[0071] [Modification examples, etc.]

[0072] The suspension support structure of the vehicle described above is an example of a preferred embodiment of the suspension support structure according to the present invention. For the suspension support 6 and the bracket 14 fixed to the suspension support 6, more specific structures can be appropriately changed without departing from the main content of the present invention.

[0073] For example, in the embodiment, the paired mounting portions 24 and 26 of the suspension support 6 (side wall portion 20) are located on different sides in the vehicle front-rear direction with the wire L1 therebetween. However, if at least their respective mounting surfaces 24a and 26a of the mounting portions 24 and 26 are located on different sides in the vehicle front-rear direction with the wire L1 therebetween, it is not required that the entire mounting portions 24 and 26 are completely located on different sides in the vehicle front-rear direction with the wire L1 therebetween. That is, the mounting portions 24 and 26 do not exist on the wire L1, or even if they exist on the wire L1, only portions with a very small amount of protrusion are sufficient. This technical solution can suppress or avoid stress concentration on the mounting portions 24 and 26, and can suppress a decrease in the rigidity of the suspension support 6 due to the mounting portions 24 and 26.

[0074] In addition, in the embodiment, the bracket 14 is fixed to the paired mounting portions 24 and 26 formed on the suspension support 6 (side wall portion 20), but the bracket 14 may also have a structure fixed to three or more mounting portions. At this time, as long as at least their respective mounting surfaces of the paired mounting portions are located on different sides in the vehicle front-rear direction with the wire L1 therebetween, and at least the mounting surfaces of the remaining mounting portions do not lie on the wire L1.
