[0002] With the continuous improvement of ABS technology in four-wheeled all-terrain vehicles (ATVs), more and more ATVs are being equipped with ABS braking systems. Meanwhile, European regulation (EU) 2015 / 68 requires ATVs with a maximum speed exceeding 60 km / h to have ABS systems. To meet these standards, domestic ATV manufacturers have added ABS braking systems to their vehicles to improve safety and compliance. Therefore, it is necessary to collect wheel speed data from ATVs to determine the proper functioning of the ABS braking system.

[0003] Therefore, a well-designed wheel speed acquisition device for four-wheeled all-terrain vehicles is needed. This device can be used to collect wheel speed data from four-wheeled all-terrain vehicles to determine whether the ABS braking system is functioning properly, meet the testing requirements for four-wheeled all-terrain vehicles, and be easy to reuse.

[0024] like Figures 1 to 3 As shown, the wheel speed acquisition device of this utility model is detachably installed on the wheel 10 of a four-wheel all-terrain vehicle. The wheel 10 is provided with a bolt 9, and a nut 8 is sleeved on the bolt 9. The wheel speed acquisition device is characterized in that: the wheel speed acquisition device includes an external bolt detachably installed on the bolt 9, a disc 1 sleeved on the external bolt, a cylindrical protrusion 3 set in the center of the disc 1, a coupling 4 connected to the cylindrical protrusion 3 at one end, and an encoder 5 set at the other end of the coupling 4.

[0025] In this embodiment, the disk 1 is provided with four arrayed waist-shaped holes 2. The length direction of the waist-shaped holes 2 is arranged along the radial direction of the disk 1. One end of the external bolt is installed on the bolt 9, and the disk 1 is installed on the other end of the external bolt through the waist-shaped holes 2.

[0026] In this embodiment, the external bolt includes an integrally formed tapered section 6-1, a cylindrical section 6-2, and a screw section 6-4. The tapered section 6-1 and the cylindrical section 6-2 are provided with internal threaded holes 6-5. The length of the internal threaded hole 6-5 extending into the cylindrical section 6-2 is less than the length of the cylindrical section 6-2. The outer diameter of the cylindrical section 6-2 is greater than the outer diameter of the screw section 6-4. The bolt 9 extends into the internal threaded hole 6-5 for connection. The screw section 6-4 is fitted with a lock nut 6-3 at its protruding end through the oblong hole 2.

[0027] In this embodiment, there are two external bolts, namely an upper external bolt 6 and a lower external bolt 7. The upper external bolt 6 and the lower external bolt 7 are arranged symmetrically, and the screw sections 6-4 of the upper external bolt 6 and the lower external bolt 7 pass through two symmetrically arranged waist-shaped holes 2 respectively.

[0028] In this embodiment, the tapered section 6-1 is set in order to reduce the cross section of the external bolt close to the wheel 10, so as to facilitate the repositioning, so that the external bolt can be fitted onto the bolt 9 after the nut 8 is removed.

[0029] In this embodiment, in actual use, the length of the internal threaded hole 6-5 extending into the cylindrical section 6-2 is set to be less than the length of the cylindrical section 6-2. This is to ensure the strength of the cylindrical section 6-2 when the bolt 9 is inserted for installation, thereby improving the strength of the connection between the cylindrical section 6-2 and the screw section 6-4, and thus improving the stability of the external bolt connection.

[0030] In this embodiment, during actual use, the outer diameter of the cylindrical section 6-2 is set to be larger than the outer diameter of the screw section 6-4, so that a step is formed at the connection between the cylindrical section 6-2 and the screw section 6-4, which limits the movement when the disc 1 is fitted onto the screw section 6-4, and a locking nut 6-3 is installed through the protruding end of the screw section 6-4, thereby achieving stable installation of the disc 1, so that the disc 1 and the wheel 10 are connected as one unit.

[0031] In this embodiment, in actual use, it can also be extended by screw section 6-4.

[0032] In this embodiment, the external bolt is provided in actual use to increase the length of the bolt 9, so as to avoid the protrusion on the wheel 10, so that when the disc 1 is installed on the external bolt, it does not affect the performance of the wheel 10 itself.

[0033] In this embodiment, the disc 1 and cylindrical protrusion 3 are set up in actual use so as to realize the encoder 5 through the coupling 4. Thus, when the disc 1 and the wheel 10 are connected as one unit, they can move synchronously with the wheel 10 of the four-wheel all-terrain vehicle, and the wheel speed of the four-wheel all-terrain vehicle can be collected through the encoder 5.

[0034] In this embodiment, in actual use, the coupling 4 can be an elastic coupling, which can mitigate impact and absorb vibration, reduce the influence of the vibration acceleration encoder 5, and improve stability and reliability.

[0035] In this embodiment, encoder 5 is set up in actual use to collect the wheel speed of the four-wheel all-terrain vehicle, so as to determine whether the wheel speed of the four-wheel all-terrain vehicle reduces braking under the ABS braking system, thereby determining whether the performance of the ABS braking system is normal.

[0036] In this embodiment, encoder 5 can be referenced from the e6b2-cwz6c encoder in actual use.

[0037] In this embodiment, in actual use, a waist-shaped hole 2 is provided, and the length direction of the waist-shaped hole 2 is arranged along the radial direction of the disc 1 so that the waist-shaped hole 2 can slide and adjust along the screw section 6-4, which greatly improves the installation adaptability.

[0038] In this embodiment, the installation position and number of external bolts can be adjusted according to actual requirements during actual use.

[0039] In practical use, the nuts 8 on the wheels 10 of the four-wheel all-terrain vehicle are removed, and the upper external bolt 6 and the lower external bolt 7 are installed on the bolt 9 through the internal threaded holes 6-5. Then, the disc is rotated so that the two symmetrical waist-shaped holes 2 correspond to the screw sections 6-4 of the two external bolts. The disc 1 is installed on the screw sections 6-4 of the two external bolts through the two waist-shaped holes 2, and the waist-shaped holes 2 are adjusted to slide along the screw sections 6-4 until the installation requirements are met. Then, the locking nut 6-3 is installed at the protruding end of the screw section 6-4 that passes through the waist-shaped holes 2 so that the disc 1 and the wheel 10 are connected as one unit.

[0040] The disc 1 moves synchronously with the wheels 10 of the four-wheel all-terrain vehicle. The encoder 5 collects the wheel speed of the four-wheel all-terrain vehicle and determines whether the wheel speed of the four-wheel all-terrain vehicle reduces braking under the ABS braking system, thereby determining whether the ABS braking system is functioning normally.

[0041] In summary, this utility model has a simple structure, and the addition of a wheel speed acquisition device enables the acquisition of wheel speed data of a four-wheeled all-terrain vehicle to determine whether the ABS braking system is functioning properly, meeting the testing requirements for four-wheeled all-terrain vehicles, and is easy to reuse.

[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
