Description

Technical Field

[0001] This utility model relates to the field of bicycle repair tool technology, specifically to a bicycle wheel hub adjustment mechanism. Background Technology

[0002] This section introduces background technology that may be related to various aspects of the embodiments of this utility model, which is believed to provide useful background information to help readers better understand the various aspects of the embodiments of this utility model. Therefore, it is understood that the description in this section is for the above purposes and does not constitute an admission of the prior art.

[0003] With the increasing popularity of high-end bicycles, bicycles are no longer just a traditional means of transportation, but also a recreational tool primarily used for leisure, sports, and entertainment. Consumers have higher demands for bicycle quality, and their requirements for the precision of wheelsets, one of the main components of a bicycle, are becoming increasingly stringent. Currently, the market offers a wide variety of bicycle sizes and types, including road bikes, mountain bikes, and full-suspension downshift bikes. The hub settings also differ between adult and children's bicycles. Bicycle wheels directly affect bicycle performance, and rim precision depends not only on the operator's skill but also on a precision rim adjuster. If the rim adjuster itself is not precise enough, the hub and rim may not be properly fixed on it, resulting in poor balance and concentricity. This level of precision is difficult to achieve with technical skill alone and can only meet basic home-use standards, not the demands of modern bicycles.

[0004] Currently, there are many types of wheel alignment stations on the market. Many lack a unified wheel alignment adjustment function, and many products suffer from structural defects, low manufacturing precision, and imprecise assembly, resulting in low alignment accuracy, cumbersome operation, inconvenience, time-consuming and labor-intensive operation, and poor alignment results. However, maintaining centering and concentricity between wheels makes adjustment difficult, necessitating the use of a wheel alignment station. A good wheel alignment station is a prerequisite for achieving the required wheel alignment accuracy, in addition to the operator's skill. Most existing wheel alignment stations on the market suffer from unstable fixing methods for the wheelset mounting bracket and measuring instrument mounting bracket, leading to large errors in wheel rigging and insufficient accuracy. Many wheel alignment stations on the market are either expensive to manufacture or have overly simple structures, poor stability, and incomplete functions. Utility Model Content

The bicycle wheel hub adjustment mechanism provided by this utility model embodiment will be described in detail below.

[0036] like Figures 1 to 6 As shown in this embodiment of the invention, an adjustment support mechanism 2 is provided on the base 1. The adjustment support mechanism 2 is detachably connected to the base 1 and can be removed from the base 1 for easy storage during transportation or when not in use. Vertical support rods 4 are respectively provided on both sides of the adjustment support mechanism 2. When disassembling or replacing the wheel set 8, the vertical support rods 4 move closer to or further away from the adjustment support mechanism 3 under the control of the adjustment support mechanism 3.

[0037] like Figures 1 to 3 As shown in this embodiment of the present invention, the adjusting mechanism 3 includes: a horizontal support rod 31 and a lead screw 33 disposed on the adjusting support mechanism 3. The two ends of the lead screw 33 are connected to the bottom of the vertical support rod 4. Rotation of the lead screw 33 drives the vertical support rod 4 to move on the adjusting support mechanism 3. Further, to increase efficiency and improve stability, the ends of the horizontal support rod 31 and the lead screw 33 are provided with fixed connecting members 34, and a drive handwheel 30 is disposed outside the fixed connecting member 34. The end of the lead screw 33 is fixed to the axis of the drive handwheel 30. The lead screw 33 may be a bidirectional trapezoidal screw with forward and reverse threads. Rotation of the drive handwheel 30 drives the bidirectional trapezoidal screw to rotate forward or reverse, causing the vertical support rod 4 to move synchronously on the adjusting mechanism 3. Three horizontal support rods 31 pass through the adjusting support mechanism 3, and the three horizontal support rods 31 are evenly distributed outside the lead screw 33. Further, the cross-section of the fixed connecting member 34 is an inverted trapezoid.

[0038] like Figures 1 to 6 As shown in this embodiment of the invention, the bottom of the detection support mechanism 5 is connected to the adjustment support mechanism 2 via a rotating shaft 51. The detection support mechanism 5 can be adjusted at its angle to the vertical support rod 4 according to actual needs, for different specifications of wheel sets 8.

[0039] like Figures 1 to 5 As shown in this embodiment of the present invention, the detection mechanism 6 includes: a radial runout detection arm component 61, on which a radial runout detection dial indicator 610 is connected via a connecting rod; the radial runout detection dial indicator 610 is provided with a radial runout detection spring needle 611; a radial roller 612 is provided at the top of the radial runout detection spring needle; the radial roller 612 abuts against the side of the wheel assembly 8 for detecting the lateral runout of the wheel assembly; and an axial runout detection arm component 62, on which an axial runout detection dial indicator 620 is connected via a connecting rod; the axial runout detection dial indicator 620 is provided with an axial runout detection spring needle 621; an axial roller 622 is provided at the top of the axial runout detection spring needle 621; the axial roller 622 abuts against the ridge of the wheel assembly 8 for detecting the positive runout of the wheel assembly. Rotate the wheelset and observe the runout of the radial runout measuring dial indicator 610 and the axial runout measuring dial indicator 620. Make fine adjustments to the wheelset until the runout of the radial runout measuring dial indicator 610 and the axial runout measuring dial indicator 620 is controlled within a reasonable range, thus completing the fine adjustment of the wheelset.

[0040] Furthermore, such as Figures 1 to 4 As shown, a disc brake pad runout detection dial indicator 46 is connected to the vertical support rod 4 via a connecting rod. The disc brake pad runout detection dial indicator 46 is equipped with a disc brake pad runout detection probe 461, the end of which abuts against the disc brake pad of the wheelset 8. By rotating the disc brake pad, the runout of the dial indicator 46 is observed, and the disc brake pad is finely adjusted until the runout of the dial indicator is controlled within a reasonable range, thus completing the fine adjustment of the disc brake pad.

[0041] like Figures 1 to 6 As shown in this embodiment of the utility model, to further increase practicality, the detection mechanism 6 further includes: a detection arm assembly 66, which includes an adapter 660. The adapter 660 is symmetrically connected to the detection arm 661 via a torsion spring. An adjusting rod 662 is provided at the end of the adapter 660 away from the detection arm 661. One end of the adjusting rod 662 passes through the adapter 660 and contacts the root of the detection arm 661. Under the action of the lever principle, the top end of one end of the detection arm 661 will open or close accordingly, thereby supporting wheel sets with different openings. Then, the angle of the measuring component and the opening size of the two detection arms 661 are adjusted so that the opening of the detection arm 661 is aligned with the edge of the wheel set. The wheel set is rotated, and the distance from the edge of the wheel set to the opening of the detection arm 661 is observed to be uniform. If there is any unevenness, corresponding adjustments are made until the entire circle is uniform, thus completing the coarse adjustment of the wheel set. The end of the detection arm 661 away from the adapter is connected to a plastic sleeve through an interference fit.

[0042] In summary, the bicycle rim adjustment mechanism provided by this embodiment ensures that the rim center aligns with the hub center during rim setting, improves the accuracy of axial and radial runout of the rim, enhances bicycle riding performance, reduces rider energy loss, and provides a more even power distribution environment. This embodiment offers advantages such as simple structure, comprehensive functions, good stability, easy and convenient operation, and simple and convenient storage and unfolding.
