Description

  The present invention relates to a railcar air spring or a coil spring height adjusting spacer. The spacer is also called a liner. Also called height adjustment washer. Hereinafter, it is referred to as an adjustment plate.

  It is necessary to adjust the height of air springs and coil springs of railway vehicles using an adjustment plate depending on the wear of the wheels and the variation of the load to be borne.

  Conventionally, an adjustment plate for adjusting a gap is interposed between a spring and a vehicle body or a carriage frame, that is, between a fixed seat of the spring and the spring. In FIG. 1, the adjusting plate 5 is interposed between the object 1 and the object 2. After the objects 1 and 2 and the adjusting plate 5 are stacked, these are fastened with a fastener. Reference numeral 6 denotes a connecting member that connects the object 1 and the object 2. The connecting member 6 includes a fastener.

  The adjustment plate 5 has a horseshoe shape when viewed from above, and is inserted between the object 1 and the object 2 from the radial direction of the connecting member 6. There is a hole through which the connecting member 6 passes in the center of the horseshoe.

  The shape of the adjustment plate is not only a horseshoe shape, but also a donut shape in which a hole through which a fastener passes is opened in the middle of the adjustment plate.

  The thickness of the donut-shaped adjustment plate is greater than the thickness of the horseshoe-shaped adjustment plate. When the gap is large, the donut shape and the horseshoe shape are selectively used by removing the upper object 1 and inserting the donut-shaped adjustment plate 5. Thereafter, the object 1 is inserted, and then the object 1 is slightly lifted, and the horseshoe-shaped adjusting plate 5 is inserted from the radial direction of the connecting member 6.

Moreover, like patent document 1, the height adjustment washer is arrange | positioned to the door and door which were attached through the hinge. The height adjustment washer is disposed between the door and the object that supports the door.
JP 2006-28993 A

  In the case of a horseshoe-shaped adjustment plate, one of the connecting members in the radial direction is open, so that the adjustment plate can be pulled out in the direction opposite to the one side. For this reason, a retaining structure for the adjusting plate is required.

  The object is to adjust the distance between the object 1 and the object 2 by interposing an adjustment plate between the object 1 and the object 2, and the adjustment plate comprises two adjustment plates, There is a recess through which the connecting member that connects the object 1 and the object 2 passes through the butted portions of the two adjusting plates, and the right and left of the butting portion with the recess interposed therebetween, Can be achieved by an adjusting plate characterized in that each has an arcuate convex portion that enters an arcuate concave portion of the other adjusting plate.

  If one adjustment plate of the pair of adjustment plates is slightly lowered from above, the convex portion of the butted portion enters the concave portion of the other adjustment plate, and the convex portion and the concave portion can be fitted to each other. That is, the unevenness is adapted. As a result, even if one or the other adjustment plate is pulled in a circular radial direction, the adjustment plate cannot be removed. For this reason, the other retaining prevention means is unnecessary. After engagement, it cannot be removed by vibration or impact. The irregularities can be circular and have the same diameter.

  In addition, for unevenness, if the division shape and the distance from the connecting member are combined several times according to the plate thickness of the adjustment plate, adjustment plates with different plate thicknesses cannot be combined with each other. It is possible to prevent the mistake of attaching the.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  An embodiment of the present invention will be described below. In FIG. 2, 10 and 20 are a pair of adjustment plates. There are an object 1 and an object 2 above and below the adjustment plate. The butted portions 10c and 20c of the adjustment plates 10 and 20 are formed with through holes 10d through which fasteners and connecting members pass. The adjusting plate 20 is also formed with a through hole 20d. The through hole 20d has a semicircular shape. The through holes 10d and 20d are formed as notches in the plan view of the adjusting plates 10 and 20, respectively, and complement each other when the adjusting plates 10 and 20 are brought into contact with each other to form a hole through which the connecting member passes. To do. The reason for forming the rectangular through hole 10d is that a pin protrudes from the object 2 toward the object 1 below. The through hole 10d is formed by providing a rectangular hole continuous with the hole in the radial direction of the same hole as the through hole 20d.

  The adjustment plates 10 and 20 are inserted between the object 1 and the object 2 by moving the right end of the adjustment plate 10 toward the right side with respect to the adjustment plate 10. The adjustment plate 20 is performed by moving from the left end toward the left side. Pins and fasteners are collectively referred to as connecting members.

  In the butted portions 10c and 20c, arc-shaped uneven portions 20a, 10a, 10b, and 20b are formed on both sides of the through holes 10d and 20d (upper and lower sides in FIG. 2). The convex portion 10 a of one adjustment plate 10 (the convex portion 10 a below the through hole 10 d) is inserted into the concave portion 20 a of the other adjustment plate 20. The unevenness is formed on both sides around the hole 20d of the fastener. The convex portion 20 b of the adjustment plate 20 is inserted into the concave portion 10 b of the adjustment plate 10. One unevenness in the radial direction (vertical direction in FIG. 2) of the hole 20d is referred to as a pair of unevenness. Concavities and convexities are on each side.

  The distance L1 from the center of the through hole 20d to the upper unevenness 10b (20b) is the same as the distance L1 from the hole 20d to the lower unevenness 20a (10a).

  Further, the diameters of the pair of arcuate irregularities 10a, 10b, 20a, and 20b are substantially the same. Explaining substantially, since the convex portions 10a and 20b are in the concave portions 10a and 20a, the diameters of both are not the same. Further, even if the adjustment plate 20 is pulled in the radial direction (rightward) from the circular recess 10b, it does not come out. In this sense, it is called substantial.

  The centers of the arcs of the convex portions 10a and 20b are located at positions projecting toward the other adjustment plates 20 and 10 from the ends of the butted portions 10c and 20c. The protruding amount is smaller than the diameter of the arc.

  That is, there are convex portions 10a and 20b and concave portions 20a and 10b on the left and right sides of the hole 20d (in the figure, on the upper and lower sides of the hole 20d). The uneven hole need not be circular, but is considered to be good. If it is circular, even if the convex portion is rotated with respect to the center, the center is easily aligned, and insertion is easier than other shapes (for example, a rectangle).

  Further, the butted portions 10f, 20f; 10g, 20g on the outer peripheral end side of the adjusting plates 10, 20 are adjusted by the adjusting plate 20 or the adjustment by the L3 dimension with respect to the reference line Rr extending in the radial direction from the center of the through holes 20d, 10d. Located on the plate 10 side. Thereby, with respect to the combination part of unevenness | corrugation 10a, 20a, 10b, 20b, the butting part 10f protrudes only L3 to the adjustment board 10 side, and the butting part 20g protrudes to the adjustment board 10 side. In this example, the upper and lower butting portions protrude by the same L3 size, but the upper and lower butting portions may protrude to different lengths. As a result, compared to the case where the butted portions 10f and 20g are on the reference line Rr extending from the centers of the through holes 20d and 10d, the butted portions 10f and 20f; 10g and 20g are combined with the recesses 20b and 10b. In this case, the fitting depth of the adjustment plates 10 and 20 becomes deep, and the deviation from the convex portions 20b and 10a can be reduced.

  Moreover, the connection part of the convex part 10a and the butting | matching part 10c of the adjustment board 10 is circular arc shape. Similarly, the connection part of the convex part 20b and the abutting part 20c of the adjusting plate 20 is also arcuate.

  If one adjustment plate 10 is lowered from above with respect to the other adjustment plate 20, the convex portion 10 a of one adjustment plate 10 is inserted into the concave portion 20 a of the other adjustment plate 20, and the convex of the other adjustment plate 20. The portion 20b is fitted into the concave portion 10b of one adjustment plate 10. If fitted, even if the adjustment plates 10 and 20 are pulled in the radial direction (left and right direction in FIG. 2), the adjustment plate 10 (20) cannot be pulled out from the other adjustment plate 20 (10) and inserted. The state is not broken.

  Reference numeral 20 e denotes a small-diameter hole provided in the outer peripheral circle of the adjustment plate 20. The object 1 below the hole 20e has a paint or stamp indicating a predetermined position. Instead of the hole 20e, a protrusion, a stamp, or a pen point may be provided on the outer peripheral end of the adjustment plate 20, and the position may be displayed by this.

  In this configuration, the assembly procedure will be described. The object 1 is raised, and the adjustment plate 10 is inserted between the object 1 and the object 2 from the horizontal direction. First, the elongated hole 10d enters the fastener protruding upward (the rotation angle of the adjusting plate 10 is maintained at a predetermined value).

  Next, the adjustment plate 20 is inserted into the gap between the body 1 and the body 2 from the side opposite to the insertion direction of the adjustment plate 10 (right side in FIG. 2). This insertion is performed by holding the adjustment plate 20 by hand. The tip of the adjustment plate 20 is positioned above the adjustment plate 10, aligned, and then lowered.

  The position of the adjusting plate 20 is determined by matching the positions of the holes 20e or the protrusions, markings, and paint with the markings or paint provided on the object 1. The position of the adjusting plate 10 is determined when the long hole 10d enters the pin. Next, when the adjustment plate 20 is lowered, the convex portion 20 b enters the concave portion of the adjustment plate 10. Further, the convex portion of the adjustment plate 10 enters the concave portion 20 a of the adjustment plate 20. As a result, the unevenness of the adjustment plate 20 is fitted into the unevenness of the adjustment plate 10.

  If the concavo-convex portion is fitted, the adjustment plate 10 and the adjustment plate 20 are prevented from being pulled out in the horizontal direction, which can be safely performed. Since the fitting part is uneven and is engaged, it cannot be removed.

  The adjustment plates 10 and 20 are inserted when height adjustment work occurs due to wheel wear and load fluctuation of the railway vehicle. In order to adjust the plate thickness of the adjustment plate, a gap is provided between the air spring or coil spring and the carriage, the adjustment plate 10 is inserted into the gap, and then the other adjustment plate 20 is inserted from the opposite side.

  According to this, the adjustment plates 10 and 20 can be made the same height, and an object (for example, an air spring or a coil spring) on the upper side of the adjustment plates 10 and 20 does not tilt.

  Instead of the hole 20e in the outer peripheral portion of the adjustment plate 20, a protruding piece that hangs down to the outside of the outer peripheral portion or downward may be provided.

  Even if the plate | board thickness of the adjustment plates 10 and 20 differs, the space | interval (L1 + L1) of 2 sets of unevenness | corrugations is the same. However, the diameter of the unevenness is different. The diameter of the unevenness is changed depending on the plate thickness. As a result, if the plate thickness of the adjustment plate is different, the small convex part can be fitted into the large concave part, but the reverse is impossible, so it is impossible to fit the uneven part and prevent the possibility of fitting another adjustment plate it can.

  In the above embodiment, the height adjustment plate of the air spring or the coil spring of the railway vehicle is shown, but the present invention can be applied to other types.

  When a pin protruding toward the object 1 protrudes from the object 2, the pin passes through the long hole 10d and positions the adjustment plate 10 (the rotation angle of the adjustment plate 10 is maintained at a predetermined value). .

  Another embodiment of the present invention will be described below. In FIG. 3, reference numerals 100 and 200 denote a pair of adjustment plates. In the first embodiment, the distance from the center of the hole 20d to the arcuate irregularities 100a, 200a, 100b, 200b is the same. However, if the distance is the same, the upper and lower surfaces of the adjustment plate 200 in FIG. There is a problem that it can be inserted into the arc-shaped unevenness of the other adjustment plate.

  In the embodiment of FIG. 3, the distance from the center of the hole 20d to the lower concave portion 200a is L2, which is smaller than the distance L1 from the center of the hole 20d to the upper convex portion 200d.

  According to this, even if it is an adjustment board with the same board thickness, an insertion mistake can be prevented.

It is a disassembled perspective view of the fastening part of the conventional object 1 and the object 2. FIG. It is a top view which shows 1st Example of the adjustment board by this invention. It is a top view which shows 2nd Example of the adjustment board by this invention.
