[0022] In the traditional ABS sensor 300 mounting structure, the sensor is fixed to a retaining ring via an ABS bushing, and the retaining ring is fixed to the bridge housing 10. During installation, the toothed ring 20 rotates and squeezes, causing the sensor to retract to adjust its position. The bushing clamping force maintains the gap between the ABS sensor 300 and the toothed ring 20. However, this structure easily leads to excessive retraction of the sensor during installation, and insufficient bushing clamping force, causing the sensor to easily shift during use.

[0023] Therefore, this application proposes a sensor assembly for use in an axle, the axle having an axle housing 10 and a gear ring 20, the sensor assembly comprising: The first support 100 is used to fix it to the axle housing 10 of the vehicle axle; The second support 200 is movably connected to the first support 100. The second support 200 can move along the axial direction of the axle housing 10 to approach or move away from the gear ring 20. The ABS sensor 300 is fixedly connected to the second support 200; The position adjustment structure 400 connects the first support 100 and the second support 200. The position adjustment structure 400 is used to adjust the relative position of the second support 200 and the first support 100 in the axial direction of the axle housing 10.

[0024] like Figures 1 to 4 As shown, in this embodiment, the first support 100 can be fixed to the outer wall of the bridge housing 10. The specific fixing method can be screwing or welding, etc. The function of the first support 100 is to provide stable support for the ABS sensor 300 and other components. A second support 200 is provided on the side of the first support 100 away from the bridge housing 10. The second support 200 is slidably engaged with the first support 100. For example, the two can be connected by a sliding rail slider. The second support 200 can move relative to the first support 100 along the axial direction of the bridge housing 10. Figure 2In the left and right direction, the second support 200 can be used to fix the ABS sensor 300. By adjusting the position of the second support 200, the gap between the ABS sensor 300 and the gear ring 20 can be adjusted, which facilitates the assembly of the ABS sensor 300. Additionally, a position adjustment structure 400 is connected between the first support 100 and the second support 200. The position adjustment structure 400 can lock the second support 200 to the first support 100, and can also release the second support 200 for position adjustment. The position adjustment structure 400 may include a threaded hole provided on the first support 100 and a bolt rotatably connected to the second support 200. The bolt is screwed into the threaded hole and can be set along the axial direction of the axle housing 10. By turning the bolt, the bolt can drive the second support 200 to move along the axial direction of the axle housing 10, thereby adjusting the distance between the ABS sensor 300 and the gear ring 20. In addition, the position adjustment mechanism can lock the second support 200 to the first support 100 after adjustment. The locking method can be flexibly designed. For example, a set screw can be screwed onto the first support 100. By screwing the set screw radially into the threaded hole and pressing against or embedding it into the side of the bolt, the bolt is prevented from continuing to rotate, thereby fixing the position of the second support 200. This solution, through the structure of the split support and the setting of the position adjustment mechanism, realizes the flexible adjustment of the gap between the ABS sensor 300 and the gear ring 20. At the same time, it improves the stability and reliability of the ABS sensor 300 when it is fixed in a fixed position, and improves the working reliability and performance stability of the ABS system. It can solve the problems of excessive retraction of the sensor during installation and insufficient clamping force after installation in the traditional ABS sensor 300 installation structure, which may cause the sensor to easily shift.

[0025] like Figure 4 An embodiment of the position adjustment structure 400 is shown, in which a connecting hole 110 is provided on the side of the first support 100 facing away from the bridge housing 10, and the position adjustment structure 400 includes: A strip hole 410 is provided on the second support 200. The strip hole 410 has a long side, which is arranged along the axial direction of the bridge housing 10. The first fastener 420 passes through the strip hole 410 and is screwed to the connecting hole 110. The first fastener 420 cooperates with the first support 100 to clamp or release the second support 200.

[0026] The first support 100 has a flat end face on the side opposite to the bridge housing 10, with a connecting hole 110 on this flat surface. The connecting hole 110 extends in a direction perpendicular to the axis of the bridge housing 10. The second support 200 has an end face that mates with the flat surface of the first support 100. The second support 200 can slide on the flat surface of the first support 100. The second support 200 has a strip hole 410, which is opposite to the connecting hole 110. The strip hole 410 has a long side and a short side. The short side is slightly larger than the diameter of the first fastener 420, and the long side is larger than the diameter of the first fastener 420. The long side is set along the axial direction of the bridge housing 10. When the first fastener 420 passes through the strip hole 410, the first fastener 420 can move in the strip hole 410 along the direction of the long side. In addition, the length of the long side can be flexibly set according to the required stroke of the ABS sensor 300. Additionally, the first fastener 420 can be a bolt or screw, with a head diameter larger than the length of the short side of the slot 410. The tail of the first fastener 420 passes through the slot 410 and engages with the threaded connection hole 110. When the first fastener 420 is tightened, the head of the first fastener 420 and the first support 100 together clamp the two sides of the second support 200. The tighter the first fastener 420 is tightened, the more reliably the second support 200 is fixed. When installing the ABS sensor, the first fastener 420 can be inserted into the slot 410 and screwed into the connection hole 110. At this time, the first fastener 420 can be loosened, and the second support 200 can be moved along the long side of the slot 410. After moving to the target position, the first fastener 420 can be tightened, and the second support 200 can be clamped and fixed between the first support 100 and the first fastener 420, completing the assembly of the ABS sensor 300. The above structure not only meets the gap adjustment requirements between the ABS sensor 300 and the gear ring 20, but also reliably locks the ABS sensor 300 when it is fixed, solving the problems of insufficient adjustment accuracy and poor fixing stability in traditional structures.

[0027] like Figure 4 In another embodiment of this application, two strip holes 410 are provided, and the two strip holes 410 are arranged on opposite sides of the ABS sensor 300 along the circumference of the bridge housing 10. The strip holes 410 are symmetrically distributed on both sides of the ABS sensor 300 along the circumference of the bridge housing 10, and the long sides of the two strip holes 410 are parallel. A first fastener 420 is provided in each strip hole 410, and the two first fasteners 420 are screwed to the first support 100 respectively. This increases the connection points between the first support 100 and the second support 200. The two strip holes 410 can share the external load, preventing local stress concentration. In addition, the two first fasteners 420 can mutually limit the movement of the second support 200, restricting it to a position that can only move along the circumference of the bridge housing 10, ensuring stability during the adjustment process, and ensuring that the end of the ABS sensor 300 is always parallel to the end face of the gear ring 20, thus ensuring the reliability of the ABS function.

[0028] In another embodiment of this application, the second support 200 is detachably connected to the ABS sensor 300. The detachable connection can be achieved in various ways. For example, the second support 200 can be provided with a threaded hole, and the ABS sensor 300 housing can be provided with a corresponding mounting hole. A bolt is passed through the mounting hole and screwed into the threaded hole to achieve a detachable connection between the ABS sensor 300 and the second support 200. This detachable connection design allows for independent assembly and disassembly of the ABS sensor 300, enabling maintenance and replacement of the ABS sensor 300 without disassembling or adjusting the second support 200, thus improving maintenance efficiency.

[0029] like Figure 3 and Figure 4 In one embodiment of this application, a first connecting portion 210 is provided on the side of the second support 200 opposite to the first support 100, and a second connecting portion 310 is provided on the side of the ABS sensor 300. The sensor assembly also includes a second fastener 500, and the first connecting portion 210 and the second connecting portion 310 are fastened together by the second fastener 500.

[0030] The first connecting part 210 can be a protrusion on the second support 200, and the second connecting part 310 can be a protrusion on the side of the ABS sensor 300. The first connecting part 210 has a threaded hole, and the second connecting part 310 has a through hole corresponding to the threaded hole. The second fastener 500 can be a bolt or screw. The second fastener 500 passes through the through hole of the second connecting part 310 and is threadedly connected to the threaded hole on the first connecting part 210, thereby fastening the ABS sensor 300 and the second support 200 together. In the above structure, the second connecting part 310 extends laterally to form an end face that abuts against the first connecting part 210, ensuring the stability of the ABS sensor 300 and the second support 200 after assembly. The second fastener 500 not only provides sufficient force to support the ABS sensor 300 against displacement under vibration, but also facilitates the assembly and disassembly of the ABS sensor 300.

[0031] like Figure 3 and Figure 4In one embodiment of this application, a limiting hole 220 is provided on the first connecting portion 210, and the ABS sensor 300 passes through the limiting hole 220. The limiting hole 220 can be a circular or elliptical hole, or other through hole adapted to the shape of the ABS. The main body of the ABS sensor 300 passes through the limiting hole 220, and the inner diameter of the limiting hole 220 can be slightly larger than the outer diameter of the ABS sensor 300 to facilitate the insertion and removal of the sensor. The axis of the limiting hole 220 is coaxial with the axis of the ABS sensor 300. During installation, the ABS sensor 300 is first inserted axially along the limiting hole 220, and then fixedly connected to the second support 200 by the second fastener 500. The dual constraint of the limiting hole 220 and the second fastener 500 on the ABS sensor 300 further enhances the anti-displacement capability of the ABS sensor 300 during vehicle operation, thereby ensuring the stability and reliability of the ABS function.

[0032] like Figure 3 In another embodiment of this application, the second connecting portion 310 is attached to and abuts against the side of the first connecting portion 210 away from the toothed ring 20. Both the second connecting portion 310 and the first connecting portion 210 can be configured as flat plates. The second connecting portion 310 can be tightly fitted with the first connecting portion 210, and the first connecting portion 210 limits the second connecting portion 310, restricting the movement of the ABS sensor 300 in the direction toward the toothed ring 20. Thus, when subjected to external impact, the second connecting portion 310 restricts the displacement of the ABS sensor 300 toward the toothed ring 20, and the second fixing member restricts the displacement of the ABS sensor 300 away from the toothed ring 20, thereby reducing the risk of displacement of the sensor due to external forces and ensuring the long-term stable operation of the ABS sensor 300.

[0033] In one embodiment of this application, the second connecting part 310 and the ABS sensor 300 are an integral structure; the integration of the second connecting part 310 and the ABS sensor 300 into a single component eliminates the assembly gaps present in the split structure, which is beneficial to improving the assembly accuracy of the ABS sensor 300, and also improves the strength and durability of the ABS sensor 300 itself. Furthermore, as... Figure 3 and Figure 4 In another embodiment, the sensor assembly further includes an elastic pad 600, which is clamped between the second connecting portion 310 and the second fastener 500. The elastic pad 600 can undergo compressive deformation under the preload of the second fastener 500. The elastic potential energy stored by the deformation of the elastic pad 600 can maintain sufficient clamping force on the second fastener 500, preventing the second fastener 500 from loosening and maintaining the stability of the ABS sensor 300.

[0034] This utility model also proposes a vehicle axle, which has an axle housing 10 and a sensor assembly fixed on the axle housing 10. The specific structure of the sensor assembly is as described in the above embodiments.
