Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a bracket for attaching a sensor, a hose or the like to a single cylinder type hydraulic shock absorber.
[0002]
[Prior art]
This type of bracket is used, for example, to attach a sensor, brake hose, etc. to a hydraulic shock absorber, and especially when used as a brake hose support, it prevents the brake hose from interfering with other members. It is used to prevent the damage. And the conventionally known bracket is fixed by fixing its sensor and hose while its cylindrical body 30 is welded or crimped to the outer cylinder 35 of the hydraulic shock absorber as shown in FIG. The portion 32 is provided at the tip of the connecting portion 31 extending from the fixed main body 30 so as not to interfere with the outer cylinder 35, and is located at a position slightly away from the outer cylinder 35. (For example, see Patent Document 1).
[0003]
By the way, the above-described conventional bracket cannot be applied to a single cylinder type hydraulic shock absorber as it is. This is because, in the single cylinder type hydraulic shock absorber, the bracket body 30 is fixed to the cylinder, so that the welding distortion or the inward protrusion is generated in the fixing method by welding or caulking. This is because the cylinder may be distorted, and the distortion of the cylinder impairs the smooth expansion and contraction of the piston.
[0004]
Therefore, a method is adopted in which the main body is formed into a C-shaped annular band, and both ends of the main body are bolted, and the main body is gripped and fixed.

[Problems to be solved by the invention]
However, the hydraulic shock absorber is generally interposed between the vehicle body and the axle of the vehicle and is used to suppress vibrations in the vehicle. However, depending on the applicable vehicle, the installation space of the hydraulic shock absorber is limited. Therefore, as shown in FIG. 3, there is a case where the fixing portion 32 such as a sensor cannot be provided in the vicinity of the main body 30 of the bracket. Accordingly, it is not sufficient to make the main body 30 of the conventional bracket only in the shape of a C-shaped ring band, and it is also necessary to extend the fixing portion 32 of the conventional bracket long upward. When vibration is applied, chatter vibration is generated in the fixed portion 32, and the fixed portion 32 may swing in the lateral direction in the figure and interfere with the single cylinder type hydraulic shock absorber to generate noise.
[0007]
Therefore, the present invention was devised to improve the above-described points, and the object of the present invention is to suppress chatter vibrations from occurring even when vibrations act on the brackets. It is to prevent the occurrence of abnormal noise by preventing the cylindrical hydraulic shock absorber and the bracket from interfering with each other.
[0008]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided a bracket for attaching a sensor, a hose, or the like to a single cylinder type hydraulic shock absorber. It has an elongated plate-like connecting portion and a fixing portion for fixing a hose, a sensor, etc. provided on the side of the tip of the connecting portion, and is near the tip of the connecting portion and is a single cylinder type hydraulic The protrusion is bulged in a direction facing the shock absorber.
[0009]
The second problem-solving means of the present invention is characterized in that, in the first problem-solving means, a rib is provided at an intermediate portion of the connecting portion.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 and 2, the basic form of the bracket according to the present invention is a C-shaped ring-shaped main body 1 that holds a single cylinder type hydraulic shock absorber (hereinafter referred to as “buffer”) 27, and the main body 1. An elongated plate-like connecting portion 10 extending in the middle and upper direction, and a fixing portion 20 for fixing a hose, a sensor or the like provided on the side of the distal end portion of the connecting portion 10. A protrusion 11 that bulges in the direction near the portion and faces the single cylinder type hydraulic shock absorber 27, and a rib 12 is provided at an intermediate portion thereof.
[0011]
Holes 2a and 2b are formed at both ends 3a and 3b of the bracket body 1 so that bolts can be inserted, and a gap between the single cylinder type hydraulic shock absorber 27 and the body 1 is formed in an annular portion of the body 1. A plurality of drain holes (not shown) are provided in order to allow rainwater, mud, and the like attached to the water to be quickly discharged from the gap.
[0012]
In order to attach the bracket to the shock absorber 27, first, the shock absorber 27 is inserted into the main body 1, and bolts are passed through the holes 2a and 2b of both end portions 3a and 3b, and both end portions 3a and 3b are connected with nuts. By tightening, the main body 1 holds the shock absorber 27 and the bracket is fixed to the shock absorber 27.
[0013]
At this time, since the protrusion 11 of the connecting portion 10 is pushed outward by the outer periphery of the shock absorber 27, the connecting portion 10 is slightly reduced, and the protrusion 11 is always pressed by the shock absorber 27. It becomes.
[0014]
Further, although not shown, for example, a brake hose, a sensor, or the like is fixed to the fixing portion 20 using the hole 21 provided in the fixing portion 20 of the bracket.
[0015]
With the above configuration, when the shock absorber with the bracket attached thereto is applied to a vehicle, the bracket is provided in the connecting portion 10 even if vibration is applied to the shock absorber and the bracket due to input from the road surface while the vehicle is running. Since the protruding portion 11 is fixed to the shock absorber 27 while being pressed against the outer periphery of the shock absorber 27, chatter vibration does not occur in the connecting portion 10 of the bracket. That is, even if the vibration is applied, the shock absorber 27 and the bracket only vibrate as a unit, and a gap is generated between the shock absorber 27 and the projection 11 of the bracket. Are prevented from interfering with each other, so that the generation of abnormal noise is prevented.
[0016]
Further, since the connecting portion 10 is provided with the ribs 12, the strength of the connecting portion 10 is also improved, so that it is possible to further suppress the vibration of the connecting portion 10, so that the shock absorber 27 and the bracket It is prevented that a gap is formed between the protrusion 11 and the noise generation prevention effect.
[0017]
In addition, since chatter vibrations are prevented from occurring in the bracket as compared with the conventional bracket, damage to the sensor, which is a precision instrument, due to vibration is suppressed, and the chance that the hose interferes with other members can be reduced. Therefore, there is an effect that damage to the hose is suppressed.
[0018]
Since a gap is generated between the shock absorber and the protrusion of the bracket, the shock absorber and the bracket are prevented from interfering with each other, and chatter vibration is prevented from occurring in the bracket. Damage and fatigue can be suppressed, and as a result, the life of the bracket can be extended.
[0019]
【The invention's effect】
According to the invention of each claim, when the shock absorber to which the bracket is attached is applied to the vehicle, the bracket is connected even if vibration is given to the shock absorber and the bracket by the input from the road surface while the vehicle is traveling. Since the protrusion provided on the portion is fixed to the shock absorber while being pressed against the outer periphery of the shock absorber, chatter vibration does not occur at the connecting portion of the bracket. That is, even if the above vibration is applied, the shock absorber and the bracket only vibrate together, and a gap is formed between the shock absorber and the projection of the bracket, and the shock absorber and the bracket interfere with each other. Occurrence of abnormal noise is prevented.
[0020]
In addition, compared to conventional brackets, chatter vibrations are prevented from occurring in the brackets, so the sensor, which is a precision instrument, is prevented from being damaged by vibrations, and the hose has the opportunity to interfere with other members. Since it can reduce, there is also an effect that hose damage is suppressed.
[0021]
Since a gap is generated between the shock absorber and the protrusion of the bracket, the shock absorber and the bracket are prevented from interfering with each other, and chatter vibration is prevented from occurring in the bracket. Damage and fatigue can be suppressed, and as a result, the life of the bracket can be extended.
[0022]
Furthermore, according to the invention of claim 2, since the connecting portion is provided with a rib, the strength of the connecting portion is also improved, so that the connecting portion can be further suppressed from vibrating, A gap is prevented from being generated between the shock absorber and the protrusion of the bracket, and the effect of preventing abnormal noise generation is further enhanced.
[0023]
Therefore, the sensor, which is a precision instrument, can be prevented from being damaged by vibration, and the opportunity for the hose to interfere with other members can be reduced, so that the effect of suppressing the hose damage and the life of the bracket can be increased. It becomes.
