Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Nastrut type front suspension device suitable for automobiles with low bonnet lines.

First, to explain the conventional device shown in the drawings, in FIG. 1, 1 is a front wheel on one side, 2 is a strut with a shock absorber 3 inside, and 4 is a part between the strut and the shock absorber. 5 is a band bumper, 6 is an insulator attached to the connection between the vehicle body T and the shock absorber 3, and the vertical force applied to the front wheel 1 is mainly caused by the coil spring 4 and the shock absorber 3. When the shock absorber is damped, an insulator 6 connected to the upper end of the shock absorber moves up and down in conjunction with the front wheel 1.

The insulator is attached to the outer cylinder 8 as shown in FIG.
, an inner cylinder 9 and a layer 10 of an elastic material such as rubber filled between the outer cylinder and the inner cylinder, the outer peripheral edge 11 of the outer cylinder is fixed to the vehicle body T, and the inner cylinder The fitted mounting plate 12 is screwed onto the upper end of the shock absorber 3.

Note that 13 is a lid that closes off the inner cylinder 9, and 14 is a hood that covers the insulator 6 above.

In recent years, many customers have begun to prefer automobiles with low bonnet lines.

On the other hand, in the conventional device having the above configuration, when the shock absorber 3 is activated, the insulator 6 that moves in conjunction with the front wheel 1 moves up and down in the same way as the lid 13 shown in dotted lines. It is necessary that a space large enough for the insulator to move up and down must be formed between them.

Therefore, in order to meet the customer's preference, the bonnet line, that is, the hood 14 is set lower than the illustrated position, and in order to form the space below the hood, the length of the shock absorber 3 is shortened and the insulator 6 is need to be lowered.

However, shortening the shock absorber 3 as described above is most undesirable because it significantly reduces the performance of the front suspension device.

In view of the above, the present invention provides a strut-type front suspension system in which when the hood covering the upper part of the insulator is provided low, the shock absorber is shortened and the insulator position is lowered, thereby allowing the hood to be placed above the insulator. Although it does not require a large space, it does not interfere with the insulator that moves up and down when the shock absorber operates, and it is possible to provide an automobile with a low bonnet line according to the customer's preference. The gist of the present invention is to provide an apparatus that includes an insulator attached to a joint between a shock absorber and a vehicle body and comprising an outer cylinder, an inner cylinder, and an elastic material layer filled between the outer cylinder and the inner cylinder. The upper periphery of the inner cylinder is approximately the same height, and the lid that closes the inner cylinder is an inverted cylindrical body with the bottom positioned upward. The point is that a through hole is provided through which the bottom of the movable lid body enters and exits.

Next, the present invention will be explained in more detail with reference to an embodiment shown in FIG. 3, in which the same parts as in FIG. 2 are given the same reference numerals. 8' is formed low so as not to protrude above the upper peripheral edge 9' of the inner cylinder 9.

Note that the upper peripheral edge 8' and the upper peripheral edge 9' may have substantially the same height.

The lid 13' that closes the inner cylinder 9 is formed of an inverted cylindrical body with a bottom 1S located above.

The hood 14 has a through hole 16 through which the bottom 15 of the lid 13', which moves up and down together with the shock absorber 6, can enter and exit.

In the device of the present invention having the above configuration, the outer cylinder 8 forms the insulator 6 when the shock absorber 3 is operated.
The outer cylinder 9 and the elastic material layer 10 move up and down together with the lid 13', but at this time, the lid 13'
Since the hood 14 is set low, the vertical movement of the insulator 6 is not hindered even if there is no large space between the hood and the insulator.

Therefore, the device of the present invention can be used in automobiles with low bonnet lines without reducing the performance of the device by shortening the shock absorber 3 or the like.

In addition, when carrying out the present invention, hot air in the engine compartment can be exhausted to the outside by simply drilling an exhaust hole in the bottom 15 of the lid 13', but the lid 13' is always closed while the car is running. Since the bottom part 15 opens and closes the ventilation hole 16 in conjunction with the front wheel 1, the movement of the bottom part can be used to forcefully or actively exhaust hot air in the engine room to the outside.

In addition, rainwater flowing into the engine room through the gap between the lid body 13' and the through hole 16 can flow out to the outside by providing a hole in the strut house, wheel house, or outer cylinder of the insulator provided below the gap. can be done.
