Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to an ABS gear ring mounting structure. Background Technology

[0002] The ABS (Anti-lock Braking System) gear ring is a key component of the brake disc. Its function is to transmit wheel speed signals through the tooth teeth, providing real-time data to the ABS controller. However, using existing mounting methods to connect the ABS gear ring to the brake disc has the following drawbacks:

[0003] When the ABS gear ring is fixed to the brake disc with bolts, the ABS gear ring is fixed to the edge of the brake disc. The bolt hole machining accuracy is required. Problems such as eccentricity and uneven torque are prone to occur during installation, which can lead to gear ring vibration or signal distortion. In addition, bolt fixing requires the opening of mounting holes on the brake disc body, which weakens the strength of the brake disc body.

[0004] When the ABS gear ring is fixed to the brake disc with bolts, the ABS gear ring is fixed to the edge of the brake disc. The bolt hole machining accuracy is required. Problems such as eccentricity and uneven torque are prone to occur during the installation process, which can lead to gear ring vibration or signal distortion.

[0005] When the ABS gear ring is fixed to the brake disc with bolts, the ABS gear ring is fixed to the edge of the brake disc. The bolt hole machining accuracy is required. Problems such as eccentricity and uneven torque are prone to occur during installation, which can cause the gear ring to vibrate or the signal to be distorted. It may also cause thermal deformation of the brake disc, affecting braking performance. It may also block the heat dissipation channel and aggravate the thermal fade of the brake disc.

[0006] When the ABS toothed ring is pressed into the brake disc and fixed together with it, the brake disc generates a lot of heat during braking, causing both the ABS toothed ring and the brake disc to undergo thermal deformation. Due to the different materials, the two sub-materials deform to different degrees, resulting in gaps in the originally tightly fitted toothed ring. Under extreme working conditions, there is a risk of it falling off.

[0007] When machining the ABS gear ring on the brake disc body, the teeth are machined on the inner end face of the brake disc body. Due to the large number of teeth (around 100), the machining time is too long and the production efficiency is low. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to provide an ABS gear ring mounting structure that can improve the installation efficiency of the ABS gear ring and the brake disc, and improve the reliability of the brake disc operation.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0010] An ABS gear ring mounting structure includes a brake disc and an ABS gear ring. The brake disc includes a brake disc body, and the ABS gear ring includes a gear ring body. The brake disc body has a central through hole, and a plurality of claws are spaced apart around the central through hole. A plurality of spring pieces are spaced apart on the gear ring body. When the ABS gear ring is mounted on the brake disc, the spring pieces engage with the corresponding claws.

[0011] Furthermore, with the central axis of the central through hole as the center, multiple pawls are circumferentially distributed on the brake disc body.

[0012] Furthermore, the claw includes a slot, the opening of which faces the central axis, and the spring clip engages within the slot.

[0013] Furthermore, on the side facing the central axis, the chuck includes, from top to bottom, a guide surface, a transition surface, an upper wall surface, a groove bottom, and a lower wall surface.

[0014] Furthermore, the distance from the upper end of the guide surface to the central axis is greater than the distance from the lower end of the guide surface to the central axis.

[0015] Furthermore, the transition surface is a vertical plane.

[0016] Furthermore, the upper wall surface is an inclined surface, and the height of the upper wall surface gradually decreases from the groove opening to the bottom of the groove.

[0017] Furthermore, the lower wall surface is a horizontal plane.

[0018] Furthermore, the gear ring body is provided with multiple limiting guide grooves at circumferential intervals, and the spring pieces are respectively located in the limiting guide grooves. When the ABS gear ring is installed on the brake disc, the pawl is located in the corresponding limiting guide groove and is guided and limited by the two side walls of the limiting guide groove.

[0019] Furthermore, the outer circumferential surface of the gear ring body is provided with an outwardly folded edge.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, an ABS gear ring mounting structure includes a brake disc and an ABS gear ring. The brake disc includes a brake disc body 1, and the ABS gear ring includes a gear ring body 2. The brake disc body 1 has a central through hole, and a plurality of claws 11 are spaced apart around the central through hole. A plurality of spring pieces 22 are correspondingly spaced apart on the gear ring body 2. When the ABS gear ring is mounted on the brake disc, the spring pieces 22 engage with the corresponding claws 11.

[0037] Preferably, with the central axis of the central through hole as the center, multiple claws 11 are evenly distributed circumferentially on the brake disc body 1.

[0038] The chuck 11 is preferably configured with 8 pieces, and the corresponding spring pieces 22 are configured with 8 pieces.

[0039] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 , Figure 11 as well as Figure 12 As shown in the figure, preferably, the claw 11 includes a groove 111 with the opening of the groove 111 facing the central axis. When the ABS gear ring is installed on the brake disc, the spring piece 22 is engaged in the groove 111.

[0040] More preferably, facing the central axis side, the claw 11 includes, from top to bottom, a guide surface 112, a transition surface 113, an upper wall surface 114, a groove bottom 115, and a lower wall surface 116.

[0041] The distance from the upper end of the guide surface 112 to the central axis is greater than the distance from the lower end of the guide surface 112 to the central axis.

[0042] The transition surface 113 is a vertical plane.

[0043] The upper wall 114 is an inclined surface, and the height of the upper wall 114 gradually decreases from the groove opening to the bottom of the groove.

[0044] The lower wall surface 116 is a horizontal plane.

[0045] The length of the lower wall 116 in the horizontal direction is greater than the length of the upper wall 114 in the horizontal direction.

[0046] Combination Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 As shown, the gear ring body 2 is provided with multiple limiting guide grooves 23 at intervals around the circumference. The spring pieces 22 are respectively located in the limiting guide grooves 23. When the ABS gear ring is installed on the brake disc, the pawl 11 is located in the corresponding limiting guide groove 23 and is guided and limited by the two side walls 231 of the limiting guide groove 23.

[0047] Preferably, the outer peripheral surface of the gear ring body 2 is provided with an outwardly folded edge 21.

[0048] The ABS gear ring of this invention is integrally stamped and formed, and the material of the ABS gear ring of this invention is stainless steel.

[0049] The following is a detailed description of the installation process of mounting the ABS gear ring onto the brake disc using the mounting structure of this utility model:

[0050] The upper surface of the ABS gear ring body 2 is pressed down by a press (not shown in the figure), pressing the spring piece 22 of the gear ring body 2 into the chuck 11 of the brake disc body 1. Before pressing, the ABS gear ring is placed on the chuck 11 of the brake disc body 1, with each spring piece 22 corresponding to one chuck 11. The spring piece 22 will be placed on the guide surface 112 of the chuck 11, and the chuck 11 is attached to the two side walls 231 of the limiting guide groove 23. During the pressing process, the ABS toothed ring slides downward along the claw 11. During the pressing process, the spring piece 22 undergoes elastic deformation due to the restriction of the transition surface 113, pressing the spring piece 22 all the way to the upper wall surface 114. At this point, the pressing stops. Since the spring piece 22 is always in a deformed state, after being pressed into the upper wall surface 114, the spring piece 22 returns to its original shape. Due to the 25° tilt angle between the upper wall surface 114 and the horizontal direction, the spring piece 22 moves downward while restoring its shape. Due to the limitation of the lower wall surface 116, the pressing depth of the ABS toothed ring is controlled. At the same time, under the restriction of the upper wall surface 114 and the lower wall surface 116, the pressure generated by the residual elastic deformation makes the ABS toothed ring tightly fit the claw 11, and there is a certain friction force, so that the ABS toothed ring will not move or fall off even under harsh driving conditions.

[0051] It achieves the positioning and fixation of ABS gear rings without the need for additional fasteners.
