Abstract

PURPOSE:To enhance the freedom of layout in a suspension arm, by pivotally supporting an end portion of the suspension arm to a shaft member, the end portion of the suspension arm being inserted into a front frame from an opening formed through an outer panel. CONSTITUTION:A front frame 1 is disposed at each side of the lower portion of an engine room so that its outer and inner panels 2, 3 form respective longitudinal closed sections 4. An opening 16 is formed through each of the front frame 1 forming portions of the outer panel 2 and also an outer panel reinforcement 18 is fastened to the outside of the outer panel 2. Besides, an end portion 12 of a suspension arm (upper arm) 8 is pivotally supported to a spindle 21 in advance at each of the supporting portions 13 of the outer panel reinforcement 18, the spindle 21 i.e., a shaft member being fastened thereto by means of a nut. Each of the supporting portions 13 is then inserted therein from the opening 16 and is enclosed in the front frame 1. The opening 16 is thus blocked by the outer panel reinforcement 18 to continue each of the closed cross sections 4, so that its required rigidity, etc., is secured.

取付装置が記載されている。In a double wishbone type front wheel suspension installed in an automobile, the base end of the lower arm is attached to a support provided at the end of a suspension cross member arranged in the vehicle width direction, and the base end of the upper arm is attached to the front suspension cross member. They are often pivoted to support parts provided at the top of the frame. The support portion of the upper arm is usually formed of a separate member from the front frame, and is disposed within the engine room. For example, in Japanese Utility Model Application Publication No. 63-15277, a shock absorber tower is provided on the hood ridge panel connected to the upper part of the front frame that is connected to the suspension cross member, and the flap wall of the shock absorber tower is attached to the engine room. A suspension mounting device for an automobile is described in which a support portion of an upper arm is formed to bulge toward the vehicle.

とが望ましい。Incidentally, in recent years, bonnets have become lower, mainly from a design standpoint. Lowering bonnets limits the space in the engine compartment, which may hinder the freedom of layout of the engine and other onboard equipment. Therefore, it is desirable that the vehicle body structure in the engine room be configured so as to limit the internal space as little as possible.

由度が妨げられるという難点もあった。However, in the conventional suspension arm support structure as described above, the support part that pivots the base end of the upper arm is located above the front frame and protrudes into the engine room. The space within the engine compartment is restricted by the support portion. Therefore, in order to secure space in the engine room, the setting position of the support portion of the upper arm tends to be pushed outward, and there is also a problem in that the degree of freedom in layout of the upper arm is hindered.

A base fm of the suspension arm is formed and inserted into the front frame through the opening [the suspension arm is pivoted to a shaft member provided within the front frame].

れている。As shown in FIG. 4, a front frame 1 provided at the front of an automobile body has an outer panel 2 and an inner panel 3.
They are arranged at the lower portions of both sides of the engine room 5 so as to form a closed section 4 in the longitudinal direction. A knuckle spindle 7 that pivotally supports the front wheel 6 is connected to the vehicle body side by an upper arm 8 and a lower arm 9, and the front wheel 6 is suspended independently on the left and right sides by a spring 10 and a damper 11 interposed between the vehicle body side and the lower arm 9. Base end 12 of the upper arm 8
A support portion 13 that swingably supports the front frame 1 is provided within the closed section 4 of the front frame 1. On the other hand, the base end portion 14 of the lower arm 9 is arranged in the vehicle width direction and is connected to the front frame 1 at both ends. The suspension cross member 15 is pivoted to the lower part of the suspension cross member 15 via a support bracket.

いる。To explain the above configuration in detail, as shown in Figure 2,
In the front frame forming part of the outer panel 2,
A rectangular opening 16 is formed, with bolt holes 17 at its four corners.
is bored corresponding to the inner panel 3, and the outer panel 2
An outer panel reinforcement 18 is fastened to the outside of the inner panel 3 and the outer panel 2 with bolts and nuts. At the lower part of the outer panel reinforcement 18, as shown in FIG. 3, a pair of box-shaped concave support parts 13 are formed inward by deep drawing, and bolt holes of the outer panel 2 are formed at the four corners. A bolt hole 19 corresponding to the inner panel 3 is provided between the front support portion 13 and a bolt hole 20 corresponding to the inner panel 3 is provided. Flanges 18a are formed on both sides of the upper portion, and are bent outward toward the front at the upper end in order to support the spring 10 and damper 11.

る。Then, as shown in FIG. 1, the front support part 13 provided on the outer panel reinforcement 18 is inserted through the opening 16 of the outer panel 2, and the opening 16 is closed by the outer panel reinforcement 18. It is assembled like this. That is, a spacer 22 corresponding to the bolt hole 17 is fixed in advance between the outer panel 2 and the inner panel 3, and the peripheral portion of the opening 16 is strongly reinforced. On the other hand, the upper arm 8 is attached to the front support portion 13 of the outer panel reinforcement 18 by a spindle 21, which is a shaft member that is fastened and fixed with a nut.
The proximal end 12 of the is pivoted in advance, and its front support part 13
is inserted through the opening 16 of the outer panel 2 and housed within the front frame 1. Both ends of the outer panel reinforcement 18 are connected to the outer panel 2, and the center part is connected to the inner panel 3 via a spacer 23, with bolts 24 and 25 passing through the bolt holes 17, 19, and 20, respectively.
It is firmly tightened and fixed by Nando. The upper part of the outer panel reinforcement 18 is joined to the outer panel 2, as shown in FIG. further extends outward and is joined to the front fender 27. In addition, in FIG. 4, 28 is a front subframe.

対して充分な強度と剛性を得ることができる。In the above structure, the opening 16 of the outer panel 2, which is concerned about a decrease in strength and rigidity, is closed by the outer panel reinforcement 18, so the closed cross section 4 is continuous, and the spacer 24, 25 and the spacer 22. 23 provides effective reinforcement laterally within the closed section 4. Therefore, sufficient strength and rigidity can be obtained against the lateral load and torsional weight received from the upper arm 8.

。Since the support portion 13 is housed within the closed section 4 of the front frame 1, the engine compartment 5
The internal space is not restricted, and the degree of freedom in the layout of the engine and onboard equipment is improved. Further, in order to preserve the space in the engine room 5, the support portion 13 is not pushed to the outside position, and the upper arm 8 can be set relatively long. Therefore, the steering stability of the vehicle can be improved. This can be confirmed from the graph in Figure 5, which shows the change in camber relative to the amount of bump on the wheel, which compares the case where the upper arm 8 is made to the required length (solid line) and the case where it is made slightly shorter (-dotted chain line). can do. That is, this graph shows that as the upper arm 8 becomes shorter, the camber change with respect to the bump amount increases, and the steering stability decreases.

The flange portion 41 is welded to the outer panel 2 in advance (and the bottom portion 43 is inserted into the bolt 4 welded to the inner panel 3).
4, it is fastened and fixed together with a spindle 45, which is a shaft member. That is, the spindle 45 has
A through hole 46 is formed through which a bolt 44 is inserted, and the base end 12 of the upper arm 8 is pivotally supported at both ends of the through hole 46 . With such a configuration, ease of assembly is improved and the same effects as in the previous embodiment can be obtained.
