Description

Technical Field

[0001] This disclosure relates to a wheel rim alignment system and a wheel rim alignment method. Background Technology

[0002] Generally, when manually straightening wheel rims, the rim must first be manually rotated while observing the runout and vibration values ​​using a dial indicator. The spoke lock caps are then adjusted based on these measurements to straighten the rim. However, manual straightening is labor-intensive, prone to human error, and inefficient.

[0092] In some embodiments, the rim alignment system 10 further includes a rim clamping unit 130 located between the first fixing plate 101 and the hub clamping unit 120, and connected to the first fixing plate 101. Specifically, the rim clamping unit 130 is located at the center of the first fixing plate 101. The rim clamping unit 130 includes a pair of second clamping portions 131 configured to clamp the rim 520 of the rim 500 from opposite sides of the rim 500 and to cause the rim 500 to roll.

[0093] In some embodiments, the rim measuring mechanism 200 includes a yaw sensing unit 210 and a bounce sensing unit 220. In some embodiments, the yaw sensing unit 210 is connected to the hub clamping unit 120 and includes a first encoder 211 configured to detect the yaw value of the rim 500 during rolling. In some embodiments, the bounce sensing unit 220 is located between the first fixing plate 101 and the hub clamping unit 120, and is connected to the first fixing plate 101. The bounce sensing unit 220 includes a rim contact member 221 and a second encoder 222. The rim contact member 221 is configured to abut against the edge 530 of the rim 500 to detect the bounce value of the rim 500 as it rolls.

[0094] In some embodiments, the spoke alignment mechanism 300 is connected to the first fixing plate 101 and is located on opposite sides of the rim receiving groove 110. In other words, the spoke alignment mechanism 300 is located on opposite sides of the rim 500 and is configured to simultaneously adjust the spokes on the rim 500 from these opposite sides.

[0095] 1-1. Hub clamping unit and yaw sensing unit

[0096] Please see Figure 2 , Figure 2 This is a schematic diagram of a hub clamping unit 120 and a yaw sensing unit 210 according to one embodiment of the present disclosure.

[0097] In some embodiments, the hub clamping unit 120 further includes a fixing block 122 and a slidable fixing plate 123. The fixing block 122 is connected to the support column 103, and the slidable fixing plate 123 is slidably connected to the fixing block 122. The first clamping part 121 is connected to the slidable fixing plate 123. In some embodiments, a slider 126 is also included between the fixing block 122 and the slidable fixing plate 123 to allow the slidable fixing plate 123 to slide relative to the fixing block 122.

[0098] In some embodiments, the first clamping portion 121 is U-shaped and further includes a first end 1211 and a second end 1212. The first end 1211 is connected to a slidable fixing plate 123, and the second end 1212 is configured to abut against the hub 510 of the rim 500.

[0099] In some embodiments, the hub clamping unit 120 further includes a power member 124 and a hub placement block 125. The power member 124 is telescopically connected between the slidable fixing plate 123 and the first clamping portion 121. The hub placement block 125 is disposed at one end of the slidable fixing plate 123 near the rim and configured for placing the hub 510, wherein a first end 1211 is fixed to the hub placement block 125.

[0100] In some embodiments, a movable joint 1201 is provided at the connection between the first end 1211, the second end 1212 and the power member 124; a movable joint 1201 is provided at the connection between the first end 1211 and the hub mounting block 125; and a movable joint 1201 is provided at the connection between the power member 124 and the slidable fixing plate 123. In this disclosure, the movable joint 1201 refers to a structure that is not fixed and locked, but rather to a structure that allows relative movement between components when they are connected.

[0101] In some embodiments, the power component 124 is a cylinder. When the hub 510 is placed on the hub mounting block 125, the extension of the power component 124 pushes the second end 1212 of the first clamping part 121 towards the hub 510 to secure the hub 510. When it is necessary to remove the rim 500, the retraction of the power component 124 causes the second end 1212 to leave the hub 510 to release the rim 500.

[0102] In some embodiments, the yaw sensing unit 210 further includes a first belt 212 and a first spring 213. The first encoder 211 is fixed to one side of the slidable fixing plate 123. The first belt 212 surrounds the first encoder 211, one end of the first belt 212 is connected to the slidable fixing plate 123, and the other end of the first belt 212 is connected to the fixing block 122 via the first spring 213.

[0103] In some embodiments, the yaw sensing unit 210 further includes a second spring 214. The second spring 214 is located on the side of the fixing block 122 away from the first encoder 211 and is connected between the fixing block 122 and the slidable fixing plate 123.

[0104] When the rim 500 rolls, if there is any left or right sway, since the hub 510 is fixed to the hub mounting block 125, it will cause the sliding fixing plate 123 to move relative to the fixing block 122. At this time, the first encoder 211 will move along with the sliding fixing plate 123, causing the first belt 212 to pull the first encoder 211 to rotate, thereby detecting the left or right sway value of the rim 500. The sliding fixing plate 123 affected by the sway can be reset by the first spring 213 and the second spring 214.

[0105] 1-2. Wheel rim clamping unit

[0106] Please see Figure 3 , Figure 3 This is a schematic diagram of a wheel rim clamping unit 130 according to one embodiment of the present disclosure.

[0107] In some embodiments, the second clamping portion 131 further includes a pair of rollers 1311 and 1313 and a pair of power members 1321 and 1323. The rollers 1311 and 1313 are respectively arranged to abut against opposite sides of the rim 520 of the wheel rim 500, and the power members 1321 and 1323 are arranged to drive the rollers 1311 and 1313 to rotate, causing the wheel rim 500 to roll.

[0108] 1-3. Bounce Sensing Unit

[0109] Please see Figure 4 , Figure 4 This is a schematic diagram of a jitter sensing unit 220 according to one embodiment of the present disclosure.

[0110] In some embodiments, the vibration sensing unit 220 further includes a second belt 223 and a third spring 224. The second belt 223 surrounds the second encoder 222, one end of the second belt 223 is connected to the wheel contact member 221, and the other end of the second belt 223 is connected to the first fixing plate 101 via the third spring 224.

[0111] In some embodiments, the wheel rim contact 221 further includes a first contact 2211, a second contact 2212, a connector 2213, a connector 2214, and a connector 2215. The first contact 2211 and the second contact 2212 have the same structure and are respectively connected to the two endpoints of the U-shaped side of the connector 2213. The first contact 2211 includes a contact area 2211-1, a connecting area 2211-2, and a contact area 2211-3. Contact areas 2211-1 and 2211-3 are configured to contact the edge 530 of the wheel rim 520, and the connecting area 2211-2 is configured to connect to the connector 2213, while also connecting contact areas 2211-1 and 2211-3.

[0112] In some embodiments, the jolt sensing unit 220 further includes a power element 225. A connector 2213 is connected to one end of a connector 2214, a second belt 223 is connected to the other end of a connector 2214, a connector 2215 is located between the connector 2213 and the second belt 223, and the power element 225 is located between the connector 2215 and the second belt 223.

[0113] In some embodiments, each of the first contact member 2211 and the second contact member 2212 has a movable joint 2201 at the position where it is connected to the connector 2213, the connector 2213 has a movable joint 2201 at the connection between the U-shaped section and the straight section, and the connector 2214 and the connector 2215 have a movable joint 2201 at the connection.

[0114] When the rim 500 rolls, the first contact 2211 and the second contact 2212 bounce up and down due to the influence of the rim 500. This causes the connecting member 2214 to swing and pull the second belt 223, which in turn pulls the second encoder 222 to rotate, thereby detecting the vertical bounce value of the rim 500. The rim contact 221 affected by the bounce can be reset by the third spring 224.

[0115] 1-4. Spoke straightening mechanism

[0116] Please see Figure 5 , Figure 5 This is a schematic diagram of one set of spoke straightening mechanisms 300 according to one embodiment of the present disclosure.

[0117] In some embodiments, the spoke straightening mechanism 300 includes a pair of straightening wrenches 310 configured to contact the brass head 540 of the rim 500 to adjust the spokes of the rim 500 (see accompanying documentation). Figure 6 ).

The locking socket 3104 is configured to contact the copper head 540 of the rim 500. The rotating gears 3101 and 3103 are configured to position the adjusting wrench 310 at different angles, allowing the adjusting wrench 310 to rotate the copper head 540 after it is engaged to adjust the tension of the corresponding spokes (see also...). Figure 6 ).

[0120] 1-5. Wheels

[0121] Please see Figure 6 , Figure 6 This is a schematic diagram of a wheel rim 500 according to one embodiment of the present disclosure.

[0122] In some embodiments, the rim 500 is a rim for an automatic motorcycle, a conventional motorcycle, or a bicycle, but this disclosure is not limited thereto. The rim 500 has a plurality of spokes (e.g., spokes 501, spokes 502, spokes 503, spokes 504, etc.), one end of each of which is connected to the inner edge of the rim 520 via a brass head 540, and the other end is connected to the outer edge of the hub 510.

[0123] In some embodiments, to avoid uneven tension of adjacent spokes that could increase or exacerbate lateral sway or vertical bounce, the spokes are adjusted in pairs, taking into account the overall balance of the rim 500. Specifically, assuming the rim 500 has a virtual centerline 550 that passes through and is perpendicular to the central axis of the hub 510, spokes 501 and 504 are symmetrical about the virtual centerline 550, forming one pair of spokes, and spokes 502 and 503 forming another pair. Alternatively, spokes that are adjacent to each other on opposite sides of the rim 500 can be grouped together. Specifically, this could be two spokes that are opposite each other on opposite sides of the rim 500 and have similar inclination or extension directions, for example, spokes 501 and 502 forming one pair, and spokes 503 and 504 forming another pair.

[0124] 1-6. Control Panel and Processor

[0125] In some embodiments, the wheel alignment system 10 also includes a control panel 410 (see accompanying documentation). Figure 1 The control panel 410 includes a processor (included within the control panel 410, not shown in the figure) configured to automatically calibrate the wheel rim based on input parameter settings and detected values. The control panel 410 is electrically connected to the wheel rim measuring mechanism 200 and the spoke calibration mechanism 300, respectively.

[0126] In some implementations, the control panel 410 is a human-machine interface configured to input calibration parameters and display sensing results. The control panel 410 is electrically connected to the yaw sensing unit 210 and the runout sensing unit 220 of the rim measuring mechanism 200, and can receive the left-right yaw values ​​and up-down runout values ​​detected by these two sensing units. Calibration parameters that can be input into the control panel 410 may include the rim size, the number and position of spokes, the maximum and minimum tension of each spoke, the standard left-right yaw value, the standard up-down runout value, the number of rolls, and the sequence of adjustment steps.

[0127] When the control panel 410 receives the left and right yaw values ​​and up and down runout values ​​detected by the yaw sensing unit 210 and the runout sensing unit 220, the processor can calculate the adjustment of the spokes based on the detected left and right yaw values ​​and up and down runout values ​​as well as the set yaw standard values ​​and runout standard values, and issue a command to the electromechanical device 420, which controls the movement angle and position of the adjustment wrench 310 to adjust the copper head 540 corresponding to the spoke to be adjusted.

[0128] 2. Wheel rim alignment method

[0129] Please see Figure 7 , Figure 7This is a flowchart of a wheel rim alignment method according to one embodiment of the present disclosure. The following is accompanied by... Figures 1 to 6 This describes the wheel rim alignment method of this embodiment.

[0130] In some embodiments, the wheel rim calibration method includes an installation step S101, a setting step S102, a rolling step S103, a measurement step S104, and a calibration step S105. The wheel rim calibration method disclosed herein repeats the aforementioned rolling step S103, measurement step S104, and calibration step S105 several times to ensure that the lateral runout and vertical runout values ​​of the wheel rim 500 conform to the set standard runout and runout values.

[0131] First, in installation step S101, the rim 500 is placed in the rim receiving groove 110, the hub 510 of the rim 500 is clamped by the hub clamping unit 120, and the rim 520 of the rim 500 is clamped by the rim clamping unit 130.

[0132] Next, step S102 involves setting the maximum and minimum tension, standard runout value, and number of rolls for each spoke of the rim 500 in the control panel 410. In addition, parameters related to the rim to be calibrated, such as size, number of spokes, and model, can be entered, as well as parameters related to the method and process adjustment, such as the number of calibration attempts and the sequence of steps.

[0133] Then, in the rolling step S103, the wheel rim clamping unit 130 is driven by the power components 1321 and 1323 to rotate the rollers 1311 and 1313, thereby driving the wheel rim 500 to roll.

[0134] Next, in measurement step S104, the yaw value of the rolling rim 500 is measured by the yaw sensing unit 210, and the bounce value of the rolling rim 500 is measured by the bounce sensing unit 220.

[0135] Finally, the correction step S105 involves stopping the rim 500 after reaching the set number of rolling revolutions, and adjusting at least two of the spokes from opposite sides of the rim 500 using the spoke correction mechanism 300 based on the yaw value and runout value measured during the previous rolling. Here, "at least two" refers to a pair of spokes located adjacent to each other on opposite sides of the rim 500, or a pair of spokes symmetrically positioned about a virtual centerline 550 that cuts the rim in half from the side.

[0136] In some embodiments, the standard yaw value is less than or equal to 1.2 mm, preferably less than or equal to 1.0 mm, and more preferably less than or equal to 0.8 mm. In some embodiments, the standard runout value is less than or equal to 0.8 mm, preferably less than or equal to 0.7 mm, and more preferably less than or equal to 0.6 mm.

[0137] In some embodiments, the calibration step S105 includes simultaneously adjusting the paired spokes. Further, calibration step S105 includes simultaneously calibrating the lateral sway and vertical runout of the rim 500, or not simultaneously calibrating the sway and runout of the rim 500. For example, after the rim 500 stops rolling, the calibration wrench 310 can simultaneously adjust the spokes based on the measured sway and runout values, or it can first adjust the spokes based on one of the sway and runout values, and then adjust the spokes based on the other.

[0138] In some embodiments, the calibration step S105 further includes adjusting at least four spokes adjacent to the position to be calibrated. Multiple spokes near the position to be calibrated can be adjusted in pairs as needed.

[0139] In some embodiments, the number of rolling revolutions set in step S102 is at least half a revolution, but can also be one or two revolutions, depending on the situation. The number of rolling revolutions refers to the number of revolutions the rim 500 needs to roll before it needs to stop for adjustment. Assuming the number of rolling revolutions is set to half a revolution, after automatic correction begins, the rim correction system 10 will detect the runout and yaw value of the rim 500 rolling half a revolution, and then stop the rim 500 from rolling and perform correction adjustment.

[0140] In some embodiments, the rolling step S103, measurement step S104, and calibration step S105 are repeated no more than nine times, and this number can be adjusted according to actual quality requirements. For example, in actual operation, wheel rims 500 that undergo calibration adjustments less than nine times are considered good products after calibration, while wheel rims 500 that undergo calibration adjustments more than nine times are considered defective products and will not undergo further calibration adjustments.

[0141] In summary, the wheel rim alignment system disclosed herein includes a wheel rim measuring mechanism and a pair of spoke alignment mechanisms, capable of simultaneously measuring the lateral runout and vertical runout of the wheel rim, and automatically aligning the spokes to reduce the runout and runout. The wheel rim alignment method disclosed herein also includes simultaneously aligning the paired spokes to maintain the overall balance of the wheel rim.
