Description

  The present invention relates to a steel plate spoke wheel run-off removal method and a steel plate spoke wheel run-out removal device that are frequently used in small two-wheeled vehicles such as motor-equipped bicycles.

    In a wheel of a small two-wheeled vehicle such as a bicycle with a motor (including a scooter type), a steel plate spoke wheel having a simple structure using a steel plate spoke formed by press-forming a steel plate in a spoke portion is often used. In the steel plate spoke foil, the portion corresponding to the hub of the wire spoke wheel is integrally press-formed as a part of the steel plate spoke. Therefore, the structure of the steel plate spoke wheel is arranged at the center of the foil for attaching the axle. An axle outer cylinder, a steel plate spoke, and a wheel rim, which are welded to each other.

    In steel plate spoke wheels, it has been pointed out that the steel plate spokes are deformed due to a collision, derailment to a road gutter, climbing on a curb, or other relatively minor accidents, resulting in vibration during running. In the production of steel plate spokes, a cross-sectional shape that can resist external forces is given by pressing, but there are limits to the three-dimensional shape that can be given by pressing, so wire spoke foil and aluminum die casting It cannot be denied that the strength is inferior to that of spoke foil.

    The use of foil that causes runout as it is has the risk of inducing new accidents and must be avoided. To that end, there is only one option of removing the distortion of the steel plate spokes that cause the vibration or replacing the foil with a new one.

    The choice of replacing the foil with a new one is, of course, a fundamental solution to eliminate the foil swing. However, for students who occupy a large demand group of small two-wheeled vehicles, it must be said that the expense of replacing with a new foil is large. In addition, there are very many types of small two-wheeled vehicles that are offered on the market today, and even repairers cannot always stock replacement wheels for various types of vehicles. Therefore, there is a problem that foil exchange is forced to wait for arrival. This problem entails the risk of eventually using a small two-wheeled vehicle that is still using a foil that causes a shake during the arrival waiting period.

    On the other hand, even when trying to repair a foil that has been distorted, with regard to steel plate spoke foil, which is relatively inexpensive, a repair methodology that removes the distortion of the steel plate spoke, and a dedicated tool or device for removing the distortion There is a problem that does not exist. The background of this problem is not only the problem of profitability of repair costs, but also the fact that it is difficult to correct a distorted foil in a technical sense.

    That is, even when the steel plate spoke wheel is shaken during actual traveling of the small two-wheel vehicle, it is impossible to determine which part of the steel plate spoke is distorted in which direction. Of course, it is a premise that steel plate spokes that are distorted to a glance can not be repaired except in exceptional cases. The target is a case where shake occurs, but it is impossible to determine which part is distorted, and most of the foil in which shake occurs corresponds to this symptom.

    The present invention pays attention to the fact that the actual vibration itself can be observed even if it is not possible to specify the distortion portion or distortion mode of the steel plate spoke that causes the vibration. An object of the present invention is to provide a vibration removal method for a steel plate spoke wheel of a small two-wheel vehicle capable of removing the vibration automatically, and a low-cost steel plate spoke wheel vibration removal device for a small two-wheel vehicle used in the vibration removal method. To do.

  The present invention adopts the following configuration as means for achieving this object.

    According to a first aspect of the present invention, there is provided a method for removing runout of a steel plate spoke wheel of a small two-wheel vehicle by attaching the wheel removed from the vehicle body to an axle horizontally disposed between a pair of fixing members disposed on both sides of the wheel. By fixing both ends to the fixing member, rotating the wheel around the axle with the both ends fixed, and by changing the distance between the rotating wheel rim and the collimating member that is located in the vicinity of the wheel rim at the maximum amplitude position of the swing of the rotating wheel rim The wheel hub and the wheel rim are connected by pressurizing in a direction that eliminates run-out along the axle direction via a booster mechanism that places the determined maximum amplitude point of the wheel rim on at least one side of the wheel rim. It is characterized by correcting the distortion of the steel plate spokes to eliminate the wheel rim run-out.

  In the method for removing runout of the steel plate spoke foil having the above configuration, the wheel is set and rotated in the same state as the actual traveling of the small two-wheeled vehicle, so that it is possible to reproduce the vibration generated in the foil, that is, the foil rim in actual traveling. . If the shake is reproduced, the maximum amplitude portion can be determined by direct viewing or by a change in the distance from the collimating member. In this case, a reasonable assumption is made that any portion of the steel plate spoke is distorted to produce this maximum amplitude location. Therefore, by applying pressure so as to push back the maximum amplitude portion of the wheel rim by using a booster mechanism, it is possible to correct the distortion of the steel plate spoke that is estimated to be distorted and eliminate the shake. Here, the correction of the distortion of the steel plate spoke does not necessarily mean only when the steel plate spoke returns to its original state, and as a result, includes the case where there is another distortion in the direction in which the shake of the foil is canceled out. .

  According to a second aspect of the present invention, a method for removing the vibration of a steel plate spoke wheel of a small two-wheeled vehicle includes arranging a pair of boosting mechanisms in an opposing posture with a wheel rim interposed therebetween, and overloading the steel plate spokes by one of the boosting mechanisms. It is characterized in that the correction is recovered and corrected by the other boosting mechanism.

  The steel plate spoke run-off removal method according to the above configuration can be recovered and corrected by the other booster mechanism arranged in the opposite direction without reversing and resetting the oil when overcorrecting the steel plate spoke. Can be increased.

  According to claim 3 of the present invention, a method for removing the vibration of a steel plate spoke wheel of a small two-wheel vehicle includes a pair of booster mechanisms arranged symmetrically in an opposing posture at an arbitrary diameter position of the wheel rim across the wheel rim. The wheel rim is simultaneously pressurized from both sides by the paired booster mechanism.

  The vibration removal method of the steel plate spoke foil according to the above configuration corresponds to the actual situation of the deflection where the maximum amplitude location of the deflection often appears in the opposite direction to the diameter position of the foil rim, and uses a pair of boost mechanisms at the same time. The runout of the steel plate spoke foil can be quickly eliminated.

  According to claim 4 of the present invention, there is provided a vibration removal device for a steel plate spoke wheel of a small two-wheel vehicle, a base table, a pair of shaft support poles standing on the base table at a predetermined interval, and a pair of shaft support poles. And a manual booster mechanism disposed on the side of at least one shaft support pole with reference to an intermediate position between the shaft support poles. Each of the pair of shaft support poles exceeds the radius of the wheel rim. A shaft hole through which the axle is inserted is formed at the same height position, and the boosting mechanism is such that the acting portion that is a member that acts on the object to be pressed is separated from the wheel rim by a radius corresponding to the shaft hole, and It is arrange | positioned in the direction which act | operates along the line segment direction which ties a pair of shaft hole formed in a pair of shaft support pole.

  The shake removing device having the above-described configuration enables the steel plate spoke wheel shake removing method according to claim 1 to be mechanically implemented. In other words, the wheel that is subject to run-out removal can be set to be rotatable in an upright state by using an axle that is inserted between the shaft holes of a pair of shaft support poles, as in actual running. Therefore, it is possible to reproduce the shake during actual running. In addition, the manual booster mechanism is located at a position corresponding to the radius of the wheel rim from the shaft hole, and manually applies pressure to the wheel rim portion of the wheel set on the shaft support pole without requiring any special positioning operation. be able to. The significance of using a manual booster mechanism is to sense the reaction force. The operating direction of the action part of the booster mechanism at this time is the direction of the amplitude of vibration, that is, the direction along the axle, and the wheel rim is pressed by pressurizing the maximum amplitude part of the reproduced wheel rim with the booster mechanism. Thus, the distortion of the steel plate spokes can be removed, and the vibration of the steel plate spoke foil can be eliminated.

  According to claim 5 of the present invention, the vibration removal device for the steel plate spoke wheel of the small two-wheel vehicle has a pair of booster mechanisms on opposite sides of the intermediate position of the distance between the pair of shaft support poles. It is characterized by being symmetrically arranged with respect to the shaft hole.

    The shake removal apparatus having the above-described configuration enables the shake removal method according to claims 2 and 3 to be mechanically performed. In the above configuration, a pair of manual boosting mechanisms exist in opposite positions on both sides of the wheel rim of the wheel set on the shaft support pole. Therefore, overcorrection by one booster mechanism can be corrected again by the booster mechanism on the opposite side. Also, the shake appearing at the symmetrical position of the wheel rim with the shaft hole as the center can be corrected simultaneously by the pair of boost mechanisms.

  According to claim 6 of the present invention, the vibration removal device for a steel plate spoke wheel of a small two-wheeled vehicle is configured such that one of a pair of shaft support poles can be moved to and away from the other shaft support pole. It is attached.

  The shake removal device having the above-described configuration can be applied to any of the shake removal methods according to claims 1 to 3, and one of the pair of shaft support poles is separated from the other shaft support pole. By being able to perform the contact operation, the wheel removed from the small two-wheel vehicle together with the axle can be set between the pair of shaft support poles for each axle, so that the number of operations can be greatly reduced. The work content to be omitted is that the attached axle is removed from the wheel, the wheel is positioned between a pair of shaft support poles, and the work axle is inserted from one shaft support pole side to the other shaft support pole side. Content.

  The method for removing the vibration of the steel plate spoke foil of the small two-wheeled vehicle of the present invention sets the wheel to a state equal to the actual running state, reproduces the wheel rim runout that appears in the actual running state due to the distortion of the steel plate spoke, and doubles it. By pressing the foil rim in a direction that eliminates the shake reproduced by the force mechanism, the steel plate spoke foil can be shaken without the need for complicated work to measure which part of the steel plate spoke is distorted in which direction. Easy to remove.

  The vibration removal device for a steel plate spoke wheel of a small two-wheeled vehicle of the present invention comprises a steel plate spoke wheel of the present invention by a combination of a mechanism for supporting the steel plate spoke wheel in a state equal to the actual running state and a boosting mechanism for pressurizing the wheel rim. The shake removal method can be mechanically and simply implemented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, about embodiment of the shake removal method of a steel plate spoke foil, it demonstrates as an effect | action of the shake removal apparatus of a steel plate spoke foil.

  The vibration removal device for the steel plate spoke foil includes a base table 1, a pair of shaft support poles 3, 3 standing on the base table 1, and a pair of base columns 2 disposed at diagonal positions of the base table 1. 2 includes manual boosting mechanisms 5, 5 and the like that are attached sideways (FIGS. 1 and 2).

  The base stand 1 is a base plate-like member for stably mounting the entire shake removing device, and is formed in a rectangular shape having an appropriate thickness. The structure of the base stand 1 can be formed by a structure in which a framework frame is packaged, a box structure of a steel plate thick plate, or the like. Moreover, a caster can also be attached to a back surface as needed.

  The pair of shaft support poles 3 and 3 are made of a steel mold, and both are fixed in an upright posture on the base table 1 by welding the base. The distance between the pair of shaft support poles 3 and 3 is set to be equivalent to the distance between the front forks of the small two-wheeled vehicle, and the steel plate spoke wheel R with an axle can be received between the two. However, in the run-off operation of the steel plate spoke wheel R, there are a case where the axle 7 of the actual vehicle is used and a case where the axle 7 prepared separately is used.

    The pair of shaft support poles 3 and 3 are arranged in the direction in which the webs 3A and 3A of the shape steel material face each other, and shaft holes 3H and 3H through which an arbitrary axle shaft 7 is inserted are provided at the same height position. The height of the shaft hole 3H is set so as to exceed the radius of the wheel rim R1 of the steel plate spoke wheel R.

  The upper ends of the pair of shaft support poles 3 and 3 are connected by a connecting member 4 in the horizontal direction, and a pair of collimators 6 and 6 are attached to the connecting member 4. Each collimator 6 includes a swingable contact 6B and a scale plate 6A for visually checking the swinging amount of the contact 6B, and is attached to the connecting member 4 via a magnet base 6M. The contact 6B is also magnetized.

  The pair of booster mechanisms 5 and 5 are positioned diagonally to the base base 1, and each of the four-joint parallel links that slidably connect the attachment positions of the four arms arranged in a rhombus are connected to the screw shaft 5A. This is a manual booster mechanism called a pantograph jack, which is based on an operation that is deformed by a rotating operation.

    Each of the boost mechanisms 5 is rotated by a rotation operation with respect to the screw shaft 5A so that the action portion 5T is connected to the center line S connecting the shaft holes 3H and 3H of the pair of shaft support poles 3 and 3 from the diagonal position of the base 1. It is welded to the base column 2 in a direction that operates along the axis (FIG. 3). At this time, the action portions 5T in each booster mechanism 5 are equally distributed on both sides across the center line CL of the interval between the pair of shaft support poles 3 and 3, and the height of the action portion 5T is 1 It is set to coincide with the height of the shaft holes 3H, 3H of the pair of shaft support poles 3, 3. Further, the acting portion 5T of each booster mechanism 5 is positioned at a position corresponding to the radius of the steel plate spoke wheel R to be worked from the shaft holes 3H, 3H of the shaft support poles 3, 3. The wheel diameter of the small two-wheel vehicle is approximately 10 inches.

  The shake removing operation in the shake removing device for the steel plate spoke wheel R having such a configuration is performed by setting the foil removed from the body of the small two-wheeled vehicle on the pair of shaft support poles 3 and 3. The wheel set consists of a dedicated axle 7 that is installed horizontally between the shaft holes 3H and 3H of the pair of shaft support poles 3 and 3, and spacers 7S... Of arbitrary thickness and steel plate spoke wheels R are alternately arranged. It is carried out by inserting and fixing with a lock nut 7N. The spacers 7S are used in combination on the left and right of the hub R3 so that the steel plate spoke wheel R does not move laterally along the axle 7 (FIGS. 1 to 3). At this time, it is not necessary to make the center position of the wheel rim R1 coincide with the center line CL of the pair of shaft support poles 3 and 3.

  Next, the pair of collimators 6 and 6 are moved laterally along the connecting member 4 so that the wheel rim R1 is sandwiched from the left and right by the pair of contacts 6B and positioned so that the indication on the scale plate 6A points to the neutral point. . Here, when the wheel rim R1 is rotated, the magnetized contact 6B swings following the rim flange portion of the wheel rim R1, so that the maximum amplitude portion of the swing can be directly read by the scale plate 6A.

  Then, the left and right maximum amplitude portions are marked on the wheel rim R1, the marked position is positioned in front of the action portion 5T of the booster mechanism 5, and the booster mechanism 5 is operated. Normally, the shake of the wheel rim R1 appears in the opposite direction with a phase of 180 degrees. In this case, the shake is eliminated in the direction (arrow K1, K2 direction in FIG. 3) by the pair of booster mechanisms 5, 5. At the same time, the wheel rim R1 can be pressurized. The external force applied by the booster mechanism 5 is applied to the steel plate spokes R2 and R2 via the wheel rim R1, and the distortion of the steel plate spokes R2 and R2 is corrected symptomatically.

  Since the pair of booster mechanisms 5 and 5 are arranged in an opposing posture with the wheel rim R1 sandwiched therebetween, overcorrection by one booster mechanism 5 can be performed without resetting the foil. It is also easy to recover and correct according to 5.

  As another embodiment of the shake removing device for the steel plate spoke foil R of the present invention, one of the pair of shaft support poles 3 and 3 is attached to the base stand 1 so as to be able to be separated from and connected to the other shaft support pole 3. It can be attached (FIG. 4).

  In this embodiment, a slide plate 1A oriented by a pair of guide members 1B, 1B is disposed on the base table 1, and the slide plate 1A is fixed to the base table 1 by lock bolts 8, 8. Yes. The bolt holes of the lock bolts 8 and 8 are formed as long holes 1H in the direction of the axle 7. One of the pair of shaft support poles 3 and 3 is erected on the slide plate 1A.

  As a result, the distance between the pair of shaft support poles 3 and 3 can be changed within the slidable range of the slide plate 1A, so that the wheel is removed from the body of the small two-wheel vehicle with the original axle 7 attached. The original axle 7 can be used as it is and set between the pair of shaft support poles 3 and 3. The work for removing the original axle 7 from the wheel and the complicated work such as the adjustment of the spacer 7S can be omitted, and the shake removal work can be completed quickly.

  In the above-described embodiment, an example in which the shake removal operation is performed with the tire removed from the wheel rim R1 has been described. However, it is also possible to perform the operation with the tire removed by removing the air from the tire. It is. This is because if the air is removed, the foil rim R1 can be directly pressurized from the side by the booster mechanism 5.

It is a perspective view which shows embodiment of the shake removal apparatus of this invention. It is a front view of the principal part in the said embodiment. It is a top view in the said embodiment. It is a top view which shows other embodiment of this invention.
