Description

Vehicle stabilizer and assembly method thereof

technical field

The present invention relates to a stabilizer used in a vehicle such as an automobile, and relates to a technique for preventing lateral deviation of the stabilizer with respect to the vehicle and improving the assemblability to the vehicle.

Background technique

Previously, stabilizers were used as spring members to suppress the roll of the vehicle when it curves. 7 is a diagram showing a conventional stabilizer. The stabilizer shown in this figure has a torsion portion 1 extending in the vehicle width direction and arm portions 2 extending from both ends of the torsion portion 1 toward the front of the vehicle. The torsion portion 1 The two ends of arm portion 2 are installed on one side of the car body, and the front end of arm portion 2 is installed on one side of the wheel. Here, a rubber bush 3 is attached to the torsion portion 1 , and the torsion portion 1 is attached to the vehicle body side through the bush 3 .

If the automobile with the above-mentioned stabilizer is installed is used to run on a curve, the car body will be inclined to the outside due to centrifugal force. On the other hand, since the wheel is in contact with the road surface, the inclined part of the vehicle body is displaced in the opposite direction on the arm part 2, and a torsional moment is generated on the torsion part 1. In addition, the torsion part 1 produces an elastic force that overcomes the torsion moment to restore the vehicle body to a horizontal state. At this time, since the stabilizer moves in the width direction of the vehicle when the vehicle body is tilted, there arises a problem that the stabilizer interferes with other components.

Therefore, in the past, as shown in FIG. 7 , on the inner side or the outer side of the bushing 3 on the torsion part 1 , the lateral deviation of the stabilizer is prevented by setting the stopper 4 . The stopper 4 is, for example, a metal ring or the like fixed to the torsion portion 1 by welding or caulking. For example, one example is also disclosed in JP-A-11-210713.

However, the distance between the bushes varies depending on the type of vehicle, and is usually 500 to 1000 mm. The gap between the bush and the stopper is set to absorb the deviation of each part described below.

(a) Deviation of the installation position of the bush to the vehicle body

(b) Dimensional deviation of the bushing

(c) The position deviation of the limiter relative to the stabilizer

In order to eliminate the lateral offset of the stabilizer and avoid interference with other parts, it is ideal that the design value of the gap between the bushing and the limit piece (hereinafter referred to as "management range") is zero, but in fact due to the above (a) ~ (c) deviation, so it is impossible to make it zero. However, if the management width is set too large, the function of preventing the lateral displacement of the stabilizer cannot be sufficiently obtained, and there is also a problem that when the stabilizer is laterally deflected, an impact load acts on the stopper, The position of the limiter is offset. On the other hand, if the management range is narrowed, although the above-mentioned problems are alleviated, it becomes difficult to attach the stabilizer to the vehicle. Considering the above points, generally the control width between the bush and the stopper on one side is set to 2-3 mm. That is, the stabilizer is laterally shifted by 2 to 3 mm on one side.

However, even with the above-mentioned control range, depending on the magnitude of the above-mentioned deviations (a) to (c), the lateral deviation of the stabilizer may increase or the installation of the stabilizer may become difficult.

Contents of the invention

Therefore, an object of the present invention is to provide a vehicle stabilizer and an assembly method thereof that are easy to attach to a vehicle and can reduce the amount of lateral displacement of the stabilizer as much as possible.

The vehicle stabilizer of the present invention has a torsion portion extending in the width direction of the vehicle, an arm portion extending from both ends of the torsion portion toward the front or rear of the vehicle, a linear portion provided near both ends of the torsion portion, and The four parts of the front end of the arm are installed on the vehicle, and the linear part is installed on the vehicle through the bushing. A stopper that moves above a specified amount.

In the vehicle stabilizer configured as described above, since any one of the bushes is restricted by the stopper, lateral displacement of the stabilizer can be restricted. At this time, it is sufficient to set the gap (management width) between the stopper and the bush in consideration of the dimensional tolerance of the bush, and the dimensional error is generally small. Therefore, the management width can be set smaller. Furthermore, even if the control range is set to be small, since the position of the other bush is not restricted, even if the bush installation position on the vehicle body side deviates, the assemblability will not be hindered. Therefore, if the vehicle stabilizer of the present invention is used, it can be easily mounted on a vehicle, and the amount of lateral deviation of the stabilizer can be reduced as much as possible.

Here, the stoppers can be arranged on both sides of the bushing. Alternatively, a limiting member can also be provided inside the bushing. At this time, the inner wall of the bush restricts both sides of the stopper.

When setting the stoppers on both sides of the bushing, there are the following forms. For example, it may also be set that the stopper has a ring shape. In this case, a notch for allowing the stopper to pass through the front end of the arm may be formed inside the ring shape. It can also be set that the limiting member has a C-shaped shape and is fixed on the straight portion by riveting. It may also be set such that the stopper has a U-shape and is fixed to the linear portion by fitting. It can also be set that the stopper is made of rubber and clamped and fixed by a metal piece.

When the stopper is provided inside the bush, for example, a hollow portion having inner walls at both ends is formed in the bush, and the stopper is restrained by the inner walls at both ends.

The method of assembling the vehicle stabilizer as described above is also one of the characteristics of the present invention. That is, in the method of assembling a stabilizer for a vehicle according to the present invention, a vehicle having a torsion portion extending in the width direction of the vehicle and an arm portion extending from both ends of the torsion portion toward the front or rear of the vehicle is used. When the stabilizer is installed on the vehicle at the linear portion near both ends of the torsion portion and the four positions at the front end of the arm portion, the linear portion is mounted on the vehicle through a bushing, and the linear portion is characterized in that Any upper part of the stopper is fixed to prevent the linear part from moving more than a specified amount in the axial direction relative to the bushing, and the linear part near the limiter is installed on the vehicle through the upper bushing, and then the other A straight section mounts to the vehicle through bushings.

Additionally, the invention is applicable to solid stabilizers as well as hollow stabilizers. Furthermore, it can be applied to a stabilizer in which the torsion part is attached to the vehicle body side and the arm part is attached to the wheel side, and to a stabilizer in which the torsion part is attached to the wheel side and the arm part is attached to the vehicle body side. Stabilizer.

Specific implementation form

Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS. 1 to 4 . FIG. 1 is a plan view showing a vehicle stabilizer 100 (hereinafter simply referred to as the stabilizer 100 ) according to an embodiment. Reference numeral 10 in the figure is a twisted portion, and the twisted portion 10 has a linear portion 11 . This linear portion 11 extends in the width direction W of the vehicle V. As shown in FIG. Arm portions 20 extending forward of the vehicle V from both ends of the torsion portion 10 in an attached state are provided at both ends of the torsion portion 10 . A flat portion 21 flattened by forging and forming a mounting hole 22 is formed at the front end of the arm portion 20 . Furthermore, a pair of stoppers 30 spaced apart from each other in the axial direction (=width direction W) are fixed to one side of the linear portion of the torsion portion 10 .

As shown in Figure 2A. The limiting member 30 forms a ring shape. Furthermore, the gap L between the stoppers 30 is set to be larger than the width of the bush 40 mounted therebetween, and in this embodiment, it is set to a dimension that adds 2 mm to the width of the bush 40 . FIG. 3A is a diagram showing the stopper 30 in detail. The stopper 30 forms a C-shape, is arranged on the straight portion 11, and is thus fixed on the inner side by riveting.

In the stabilizer 100 having the above structure, the linear portion 11 of the torsion portion 10 is mounted on the vehicle body side, and the flat portion 21 of the arm portion 20 is mounted on the wheel side. When installing, first insert a bushing 40 between the stoppers 30 and install it on the linear part 11. After installing the other bushing 40 on the straight part 11, install it on the stopper 30 according to the One side of the bush 40 in between, and one side of the other bush 40 are installed on the vehicle body side in this order. Then, the flat portion 21 is attached to the wheel side. Alternatively, the flat portion 21 may be attached earlier than the bush 40 .

According to the stabilizer 100 of the above structure, since one bush 40 is limited by the stoppers 30 on both sides thereof, the lateral offset of the stabilizer 100 is limited to 1 mm on one side. If this stabilizer 100 is used, since the other bush 40 is not restricted, it can be easily mounted on the vehicle V, and the amount of lateral displacement of the stabilizer 100 can be minimized.

In addition, although the stopper 30 is caulked and fixed to the linear portion 11 of the torsion part 10 in the above-mentioned embodiment, the form of the stopper 30 is arbitrary. For example, as shown in FIG. 3B , a U-shaped stopper 30 may be fitted into the straight portion 11 to fix it. Furthermore, as shown in FIG. 3C , a rubber stopper 30 may be installed on the linear portion 11 and clamped and fixed by a metal piece 32 . Moreover, as shown in FIG. 4 , a notch 31 for passing the flat portion 21 may be formed on the annular stopper 30 , and the stopper 30 is inserted from the end of the stabilizer 100 and fixed with the straight portion 11. . In addition, arbitrary methods such as riveting, welding, and bolting may be used for the fixing method of the stopper 30 . Also, the present embodiment is applicable to both solid stabilizers and hollow stabilizers.

5 and 6 are diagrams showing other embodiments of the present invention. FIG. 5 is a plan view showing a vehicle stabilizer 200 (hereinafter referred to simply as the stabilizer 200 ) according to this embodiment. In this embodiment, a stopper 50 is fixed on one side of the linear portion 11, and a bushing 60 is installed around the stopper. As shown in FIG. 6, a hollow portion 61 is formed in the bush 60, and the stopper 50 is restrained by inner walls 61a at both ends of the hollow portion. The gap L between the inner walls 61 a is set larger than the width of the stopper 50 , and in this embodiment, the width of the stopper 50 is set to a dimension that adds 2 mm. In addition, a bush 70 is also mounted on the other side of the linear portion 11 . The bush 70 is formed to be equal in size and limit to the bush 60 , and may or may not have the hollow portion 61 .

Also according to the stabilizer 200 as described above, the same operations and effects as those of the above-mentioned embodiment can be obtained. In particular, in this embodiment, since the stopper 50 is accommodated inside the bush 60, there is an advantage that the form becomes compact.
