Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the structure of a suspension tower portion for fixing a strut of a suspension device.

(Prior Art) It has been known to fix the upper part of the strut of a suspension device to a suspension tower provided in a wheel house using bolts. (Refer to Japanese Utility Model Publication No. 55-81409) In addition, a protrusion is provided on the mounting member, a recess is formed in the vehicle body corresponding to the protrusion, and the mounting member is mounted at a predetermined mounting position to prevent incorrect strut assembly. There are also known things that can prevent it. (Refer to Japanese Utility Model Publication No. 57-3006.) However, with the conventional structure, when assembling on the production line, the bolts installed at the top of the struts do not fit smoothly into the bolt holes provided on the top surface of the suspension tower. The reality was that the strut had to be inserted by shaking the strut without anyone being able to see it. Therefore, there was a problem that the workability was very poor.

(Purpose of the invention) The present invention was made in view of the above-mentioned problems, and it is possible to replace the vehicle body mounting bolts provided on the struts with the suspension towers without bothering workers during assembly on the production line. This provides a suspension tower section that can be inserted into a bolt hole.

(Structure of the invention) The structure of the invention to achieve the above object is to fix the upper end of the strut of the suspension device to the upper surface of the suspension tower provided in the wheel house via a mounting member. , a plurality of bolts provided so as to protrude upward from the top surface of the mounting member, bolt holes provided on the top surface of the suspension tower portion to correspond to the bolts, and an inner vertical portion of the suspension tower portion. provided between the wall and the mounting member, and a first portion of the mounting member;
a first guide means for defining a position in a specific direction and a second guide means for defining a position in a second specific direction; The bolt is set upward from a lower position that is longer than the length corresponding to the protrusion amount of the bolt, and the first guide means includes a guide member that protrudes inwardly from the inner vertical wall and that allows the mounting member to move in the first specific direction. The present invention is characterized in that a guide portion is provided that gradually decreases the capacity from the bottom to the top and guides the bolt to the bolt hole.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a front view showing a rear suspension device 1, and 2 is a frame provided in the longitudinal direction of the vehicle body. are strongly connected by. One end of a lateral link 4 constituting the suspension device 1 is pivotably attached to the lower part of the cross member 3, and the lateral link 4 swings downward (hanging of the lateral link 4). A rebound stopper 3a is fixed to regulate the amount. The lower end of a strut 5 constituting the suspension device 1 is pivotally attached to the other end of the lateral link 4, and the strut 5 is connected to a shock absorber 6 having a piston 6a and a cylinder 6b. , and a coil spring 7 to prevent shocks and vibrations from tires (not shown) from being directly transmitted to the vehicle body.

A mounting member 9 is provided at the upper end of the strut 5 (upper end of the piston 6a) and is fastened together with bolts to an upper plate 8 that supports the upper end of the coil spring 7. Two bolts 10 are fixed by welding, and a mounting member 9 corresponding to the bolts 10 is provided.
A convex portion 11 projecting outward is provided on the periphery of each. (See FIG. 4) Note that reference numeral 12 is an elastic member provided to prevent vibrations etc. from the suspension device 1 from being directly transmitted to the vehicle body.

Reference numeral 13 denotes a suspension tower part provided in a wheel house (not shown), and the upper surface of this suspension tower part 13 has an opening 14 into which the upper part of the strut is inserted, and the mounting member 9.
A bolt hole 15 is provided into which the bolt 10 provided on the inner vertical wall is inserted, and a guide member (corresponding to the guide part in the claims of the utility model registration) is provided at a position corresponding to one of the bolt holes 15 on the inner vertical wall. ) 16 is attached, and at a position corresponding to the other bolt hole 15 there is a bulge 17 whose inner vertical wall bulges inward.
is formed.

As shown in FIGS. 2 and 3, the guide member 16 has a substantially U-shaped cross section, and is slightly larger than the width of the convex portion 11 and widens toward the bottom. has been done.

In addition, in this embodiment, the guide member 16 and the bulge 1 are arranged so that the convex portion 11 is located at a position corresponding to the bolt 10.
7 is provided at a position compatible with the bolt hole 15, but in short, the convex portion 11 contacts and is guided by the guide member 16 and the bulging portion 17, and the bolt 10 is smoothly inserted into the bolt hole 15. Of course, the position is not limited to this, as it is only necessary to do so.

Further, in this embodiment, the rear suspension tower section has been described in the rear suspension device 1, but it goes without saying that the present invention may also be applied to the front side.

Next, the order of assembling the suspension device 1 to the vehicle body will be described in detail.

Normally, on a production line, the car body is lifted up using a lift to make it easier for workers to work, and the suspension device 1 attached to the cross member 3 is lifted up and fixed there. First, the cross member 3 is firmly connected to the frame 2 with bolts. At this time, the strut 5 is housed in the suspension tower section 13, and the rebound stopper 3a restricts the downward swinging of the suspension device 1 to prevent the strut 5 from falling off.

This rebound stopper 3a is provided at a rebound position further lower than the lower rebound required for normal driving, and the above-mentioned convex portion 1
1 is housed in the guide member 16, and the other protrusion 11 is provided at a position such that it abuts against the bulge 17.

Next, after tires etc. are attached to the suspension device 1, the vehicle body and the suspension device 1, which had been lifted by a lift etc., are lowered to the ground.
Because the vehicle body and the suspension device 1 approach each other due to the weight of the vehicle body at that time, one of the convex portions 11 is guided by the guide member 16 while restricting its movement in the longitudinal direction of the vehicle body, and the other convex portion 11 is guided by the bulge portion of the vehicle body. Movement in the width direction is restricted so that the bolt 10 can be smoothly inserted into the bolt hole 15.

In this embodiment, one of the recesses 11 and the guide member 16 constitutes a first guide means, and the other recess 11 and the bulge 17 constitute a second guide means.

With the above configuration, after the temporary setting of the suspension device 1 when the cross member 3 is fixed to the frame 2, the lift-down process can be smoothly carried out by the weight of the vehicle body without any operator intervention. Since the bolt 10 can be inserted into the bolt hole 15, work efficiency can be greatly improved.

(Effect of the invention) The effect of the invention with the above configuration is that it can provide a suspension tower part that can be assembled extremely easily without bothering the operator when assembling the strut of the suspension device to the vehicle body. be.
