Abstract

PURPOSE:To eliminate dead space, by providing an L-shaped suspension arm rotatably mounting its one end to an axle side member of a front wheel and mounting a coil spring to be interposed toward the direction of a lateral width of a car body between the other end of said arm and the car body. CONSTITUTION:Of the suspension arms provided between the bottom end of a knuckle 1, which serves for an axle side member of supporting a wheel 11, and a floor 12 of a car body, a lower arm 2 is formed to an L shape. And a coil spring 6 is mounted interposing toward the direction of a lateral width of the car body between the upper end of the lower arm 2 and one part 14 of the car body. In this way, the coil spring 6 is provided to be arranged in a triangular space part which has been dead space in the past. Accordingly, in the case of a front wheel driven car, the coil spring 6 is prevented from obstructing the existence of a driving shaft. While the coil spring 6 enables its stroke to be small decreased from lever ratio between the rotary center of the lower arm 2 and the acting point of the coil spring 6 in a position of the wheel 11.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention eliminates dead space by changing the arrangement of springs that form part of a suspension system.

This relates to a suspension system for a vehicle.

(Prior Art) Many vehicles such as automobiles use coil springs for front and rear wheel suspension. Figures 3 to 5 show examples of using coil splinters for front wheel suspension of automobiles. It is. The ones in FIGS. 3 and 4 are strut type, and in this case, the lower arm of the suspension arm is connected between the lower end of the knuckle l to which the axle (not shown) is attached and the lower part of the floor of the vehicle (not shown). 2 as axis 3, 4
The upper end of the knuckle 1 and the upper part of the vehicle body are connected by a strut 5. In the case shown in FIG. 3, a coil spring 6 is interposed between the intermediate portion and the t-end portion of the strut 5, and in the case shown in FIG. is interposed. The thing in Figure 5 is the upper end of the knuckle l and the protrusion 7 of the car body.
The upper arm 8 is connected to the axis 9. The coil spring 6 is installed at the same position as shown in FIG. 4.

(Problems to be Solved by the Invention) Among the above conventional techniques, the one shown in FIG. 3 has a problem in that the winding diameter of the coil spring 6 is larger than the strut diameter, which requires space. The thing is F,
In the case of F cars, there is a problem of running out of space to pass the drive shaft.

The present invention has been made in view of this point.

(Means for Solving the Problems) As a means for solving the above problems, the present invention provides an L-shaped suspension arm with one end pivotally attached to the axle side member of the front wheel, and the other end of the suspension arm. A coil spring oriented in the width direction of the vehicle body is interposed between the vehicle body and a portion of the vehicle body.

(Function) With this configuration, the coil spring will be located where there was conventional dead space, so space can be saved, and in the case of F and F cars, there is no need to pass the drive shaft through. It will have no impact.

(Embodiment) An embodiment of the present invention will be described with reference to FIG. 1 and FIG. The lower arm 2 of the suspension arms provided between the lower arm 2 and the floor tunnel is L-shaped, and a coil oriented in the width direction of the vehicle body is disposed between the upper end of the lower arm 2 and a portion 14 of the vehicle body. A spring 6 is interposed. Reference numeral 15 in FIG. 1 is the centerline of the vehicle body, 16 in FIG. 2 is a dash board, 17 is a steering gear box, 18 is a differential case, and 19 is a roughly triangular space that was conventionally a dead space.

As shown in FIG. 2, since the coil spring 6 is disposed in this space, it does not interfere with the drive shaft in the case of F and F cars, and also allows the rotation center of the lower arm 2 and the wheel 11
Since the stroke of the coil spring 6 can be made small based on the lever ratio of the point of action of the coil spring 6 at the position, the overall length can be shortened and does not reach the floor tunnel 13. The strut 5 and the coil spring 6 act to absorb the impact when the wheel 11 swings in the vertical direction while the vehicle is running.

(Effect of the invention) Since the present invention is configured as explained above,
The coil springs, which conventionally took up a relatively large amount of storage space, are now housed in what used to be dead space, resulting in a larger space in the engine room and the legroom of the front seats. Also, when looking at the vehicle from the side, the drive shafts and coil splinters that reach the wheels from the differential center are shifted from front to back, so F
, even in the case of F cars, it does not interfere with the drive shaft.
