Abstract

PURPOSE:In a bracket for supporting tubular member of shock absorber by means of an annular section to be formed with arched sections in outside and inside bodies, to insert the tubular member smoothly without biting by enlarging the end section of arched section of outside body. CONSTITUTION:A bracket for fixing the tubular member 10 of shock absorber to the chassis is comprised of an outside body formed into U-shaped cross- section by means of a pair of foot sections 2, 3 projected in parallel from both ends of an arched section 1 and an inside body 8 formed into M-shaped cross- section by means of a pair of foot sections 6, 7 projected in parallel from both ends of an arched section 5. The tubular member 10 is supported by an annular section comprised of both arched sections 1, 5. Here an enlarged section 16 is provided at the upper end of circumferential central portion 1a of arch in said arched section 1 while an inclined face 16a is formed at the lower end. Consequently the tubular member 10 can be inserted smoothly without biting.

Description

[Detailed Description of the Invention] The present invention is a bracket for a shock absorber - a tube body for a shock absorber? This relates to the bracket F for mounting on the vehicle body.

This type of bracket generally has a +4J? Menu U
The cross section is formed into an M-shaped cross section by a 1 μm outer 1 body 4 formed in a letter shape, and a pair of parts 6.7 protruding approximately parallel to each other from the circular arc portion 5 and the circular arc portion 50. The inner 1h consists of 11 bodies 8, and the inner 11111 bodies 8 are the outer 11 bodies.
It is attached by welding 9...9 etc. between the 1141 parts 2.3 of the 111 body 4, and these outer body 40 arc-shaped part 1 and inner body 8
An annular portion for receiving the cylinder is formed using the arcuate portion 5, and the cylinder 10 of the shock absorber is inserted into the annular portion. Reference numeral 11 indicates a bolt hole provided in the leg. Figure 3 shows the state of attachment of the bracket to the vehicle body, and B indicates the bolt hole provided in the leg. 2, 3.
6.7 The axle 13vr is attached to the axle 13vr with bolts and nuts 12, etc., with the VC rotated in the outward direction of the left and right sides of the vehicle (outward direction of the vehicle width). Note that 14 is a brake hose, and 15 is a hose support that is attached to the outer circumferential surface of the bracket B in order to support the brake hose 14 along the outer circumferential surface of the bracket B.

By the way, in conventional brackets of this type,
As shown in the figure, the rib portion 4a is formed by bending the upper and lower ends of the outer body 4 outward.

4bis are formed, and the rib parts 4a and 4b form one outer body 4?
In addition to strengthening the ffA, the rib portion 4a at the upper end can be effectively used as a guide especially when inserting the 10 cylinders. The bracket with such a configuration is designed to prevent the brake hose 14 from interfering with the lip portion 4aK.
5 height h? Is the distance between the rib portion 4a and the brake hose 14 g? Thoroughly remove the brake hose 14.
There is no problem with the car model that has a structure that prevents it from being fixed to the VR car body so that it is kept away from B, but the hose support 15
・The height h′l? L- It must be as low as possible and the 14 brake hoses must be in close contact with the outer peripheral surface of the bracket as much as possible, and - In the case of a vehicle that has a structure that must be secured to the vehicle body along the vicinity of the cylinder 10, the rib portion 4a must be placed as low as possible. Brake hose] 4 is the impression of the vehicle, cylinder body 1 with camphor
As the hose 14 rotates, interference occurs, causing damage to the hose 14.

Therefore, for the above-mentioned car models that do not have enough space,
As shown in Figure 4.5, there is almost no interference with the brake hose 14! At the lower end of the 111 body 4, as before,
A bracket is used at the upper end of the outer body 4 where rib portions 4bv are formed but interference with the brake hose 14 is likely to occur, but a bracket is used which does not form rib portions 4a%', as shown in Fig. 1.2. Compared to the bracket v shown in the cylindrical body 10v
Difficult to insert, cylindrical body 10? If so-called cracks occur when inserting the cylinders, or if there is a step d between the upper part of the arcuate part 1 and the upper end of the leg part 2.3, the cylinders 11 may Tilt (fall) V is caused.

Such a malfunction is shown in Figure 6 f.5Vr cylinder 1 ()
This problem can be solved by chamfering the lower end or the upper end of the arcuate portion l using a keg grinder or the like.

Chamfering work using 7 grinders is extremely troublesome and a waste of man-hours. was spending. .

Does the present invention have the above-mentioned problems and drawbacks of the conventional technology? This was created for the purpose of solving the problem, and its gist is as shown in the drawings from FIG. This is to prevent the cylindrical body 10 from being jammed during press-fitting.

In the figure, reference numeral 16 denotes an enlarged diameter section, and the lower end of the enlarged diameter section 16 is an R-shaped inclined surface 16a, so that the cylinder 10v can be inserted smoothly without any jamming.

Reference numeral 17.13 denotes a non-enlarged diameter portion extending in the circumferential direction Vr from the enlarged diameter portion 16, and these non-enlarged diameter portions 17.18 are located on opposite surfaces in the longitudinal direction of the vehicle, and The cylindrical body 10'l is closely engaged with the force f applied in the longitudinal direction of the vehicle:
It is designed to firmly support the cylindrical body 1 and prevent it from being damaged. Note that 19 is a tapered enlarged diameter portion provided at the upper end of the arcuate portion 5 of the inner body 80, and the enlarged diameter portion 19, together with the enlarged diameter portion 16 of the outer 11111 body 4, has a larger diameter. This further facilitates the insertion of the cylinder 10.
It should be noted that the same parts as in the prior art are given the same reference numerals and redundant explanations will be omitted.

Above 1. As described above, the present invention includes: an outer body having a substantially U-shaped cross section formed by an arcuate portion and a pair of legs protruding substantially parallel from both ends of the arcuate portion; It consists of an inner body with an M-shaped cross section formed by a pair of legs protruding substantially parallel from both ends of an arcuate part, and the inner body is attached between the legs of the outer body. In this shock absorber, an annular part for receiving a cylinder is formed by the arc-shaped parts of the outer body and the inner 11 parts, and the cylinder of the shock absorber is inserted into the annular part to support it. In this bracket, the diameter of the upper end of the arcuate portion of the outer body in the circumferential direction of the arc is enlarged to facilitate insertion of the cylindrical force, resulting in the following effects.

(1) Troublesome chamfering work using a grinder or the like becomes unnecessary (diameter expansion work is easier than chamfering work because it is formed at the same time in the press process).

(2) The upper end of the circumferential center of the arc of the outer body? Since the diameter has been expanded, the leg side of the cylinder when inserting the WJ body.
The tilt (fall) of ＼ should be as protected as possible.

(3) Since there is no need to provide a lip that extends radially outward from the bracket, damage to the brake hose due to interference with the brake hose is eliminated.
