Description

Technical Field

[0001] This invention relates to the field of brake disc bushings, specifically brake disc bushings with bridging components. Background Technology

[0002] A brake disc is a friction pair in a disc brake. In addition to the strength and rigidity required as a component, it should also have the highest possible and most stable coefficient of friction, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity. For example, automobiles may use wheel braking systems that include multi-disc brake assemblies. For instance, a multi-disc brake assembly may include multiple rotors engaged with the wheel and multiple stators interleaved with the rotors. The rotors and wheels are configured to rotate about an axis, while the stators remain stationary. In order to slow down the rotational motion of the rotating wheel, the brake assembly may displace a piston against a pressure plate to press against the stationary stator against the rotating rotor attached to the wheel, thereby generating a torque that slows down the rotational motion of the wheel. In some examples, the rotor may engage with the wheel via a rotor drive key located on the inner surface of the wheel.

[0003] As can be seen from the brake disc bushing with bridging member disclosed in CN113550991A, the rotor can be defined by a slot configured to receive the rotor drive key. A bushing is usually provided on the outside of the rotor to reduce rotor friction and protect the rotor. The bushing is mostly installed on both sides inside the rotor slot, and the rotor is located between the two bushings.

[0004] Brake disc bushings are mostly installed inside the rotor groove on the edge of the brake disc via a bridging plate. During the use of the brake disc, the bushing vibrates with the brake disc. The bridging plate is located near the bottom of the bushing. The bridging plate has a good fixing effect on the bottom between the two bushings. However, most existing bushings do not have a fixing effect on the top, which leads to a decrease in the fixing effect of the top of the bushing. Therefore, we propose a brake disc bushing with a bridging component. Summary of the Invention

[0005] The purpose of this invention is to provide a brake disc bushing with bridging components, which can improve the stability of the bushing during use and prevent the bushing from falling off.

[0006] To solve the above problems, the present invention adopts the following technical solution: A brake disc bushing with bridging components includes a brake disc, wherein a rotor groove is formed on the circumferential surface of the brake disc, and bushings are provided on both sides inside the rotor grooves, and a bridging plate is provided between the two bushings near the brake disc. Both bushings are rotatably connected to abutting rods via torsion springs. There are four abutting rods, and the ends of the four abutting rods away from the bushings abut against each other. The two abutting rods on the right side are movably connected to insert rods at the ends away from the bushings. Magnetic blocks are provided at the ends of the two abutting rods on the right side away from the bushings and at the ends of the insert rods. An ejector spring is provided inside the left end of the insertion rod. A locking block is provided at the end of the ejector spring near the abutment rod. A roller is rotatably connected inside the locking block at a position away from the ejector spring. A locking groove is provided inside the abutment rod at a position away from the bushing, and the positions of the locking block and the locking groove correspond to each other.

[0007] As a preferred embodiment of the present invention, the front and rear surfaces of the brake disc are provided with limiting grooves, and there are four limiting grooves. All four limiting grooves are connected to the rotor groove, and the four limiting grooves are respectively located on both sides of the rotor groove.

[0008] As a preferred embodiment of the present invention, limit blocks are provided on the front and rear surfaces inside the two bushings, and the four limit blocks correspond to the positions of the four limit grooves respectively, and the four limit blocks are located inside the four limit grooves respectively.

[0009] As a preferred embodiment of the present invention, the surface of the bridging plate away from the brake disc is slidably connected to a slider, and two sliders are provided. The surfaces of the two sliders away from the bridging plate are rotatably connected to support rods, and the ends of the two support rods away from the sliders are respectively rotatably connected to the inner surface of the bridging plate at positions away from the sliders.

[0010] As a preferred embodiment of the present invention, the surface of the bridging plate away from the brake disc is provided with mounting blocks, and there are four mounting blocks. A mounting rod is provided between every two mounting blocks, and the two sliders are respectively slidably connected to the outer surfaces of the two mounting rods.

[0011] As a preferred embodiment of the present invention, a return spring is sleeved on the outer surface of each of the two mounting rods. The two return springs are respectively located between the two sliders and the two mounting blocks located in the middle, and the two ends of the return springs abut against the surfaces of the sliders and the mounting blocks, respectively.

[0012] As a preferred embodiment of the present invention, the surface of the bridge plate away from the brake disc is rotatably connected to a rotating rod, and there are two rotating rods. Both ends of the two rotating rods are rotatably connected to connecting rods. The ends of the four connecting rods away from the rotating rods are respectively rotatably connected to the front and rear surfaces of the two bushings at positions away from the rotating rods.

[0013] As a preferred embodiment of the present invention, connecting springs are provided on the front and rear sides of the two rotating rods near the bushing surface, and four connecting springs are provided. The ends of the four connecting springs away from the rotating rods are respectively provided on the front and rear surfaces of the two sliders.

[0014] As a preferred embodiment of the present invention, positioning grooves are provided on the surfaces of the two bushings near the bridge plate, and the two sides of the bridge plate are respectively located inside the two positioning grooves. A push rod is movably connected inside the bushing away from the brake disc, and the position of the push rod corresponds to that of the abutment rod. A buffer pad is provided on the inner surface of the bushing, and the buffer pad is in close contact with the outer surface of the brake disc. Six rotor grooves are provided.

[0015] Compared with the prior art, the advantages of this invention are: (1) This solution uses abutment rods to fix the two bushings. During the bushing installation process, the push rod can be moved to push the abutment rod out from the inside of the bushing. The spring force of the torsion spring can drive the abutment rod to rotate, so that the two abutment rods can abut against each other to fix the bushing, increase the stability of the bushing during use, and prevent the bushing from falling off during use.

[0016] (2) This solution can connect the bridge plate and the bushing by setting a rotating rod and a connecting rod. The end of the connecting rod away from the rotating rod is set on the front and rear sides of the top of the bushing, which can support the top of the bushing and increase the stability of the top position of the bushing during use, thereby preventing the bushing from falling off during the use of the brake disc.

[0017] (3) The bushing is fixed by the bridge plate set in this scheme. The bridge plate is U-shaped. The spring force of the reset spring can drive the slider to move. With the support rod, the two sides of the bridge plate can be supported, thereby increasing the strength of the bridge plate and preventing the bridge plate from bending on both sides during use.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0031] Please see Figure 1-9 A brake disc bushing with bridging components includes a brake disc 1. A rotor groove 101 is formed on the circumferential surface of the brake disc 1. Bushings 2 are provided on both sides inside the rotor groove 101. A bridging plate 3 is provided between the two bushings 2 near the brake disc 1. The bushings 2 are first placed inside the rotor groove 101, and then the bridging plate 3 is placed between the two bushings 2 so that both sides of the bridging plate 3 are in close contact with the surfaces of the bushings 2, thereby fixing the bushings 2. Positioning grooves 201 are formed on the surfaces of both bushings 2 near the bridging plate 3, with each side of the bridging plate 3 located in one of the two positioning grooves 201. Inside the bushing 2, a push rod 208 is movably connected at a position away from the brake disc 1, and the position of the push rod 208 corresponds to that of the abutment rod 203. During the installation of the bushing 2, the push rod 208 is in close contact with the brake disc 1, which can drive the push rod 208 to move and push out the abutment rod 203. A buffer pad is provided on the inner surface of the bushing 2, and the buffer pad is in close contact with the outer surface of the brake disc 1. Six rotor slots 101 are provided. The buffer pad can buffer the friction between the bushing 2 and the brake disc 1, avoid damage to the bushing 2 and the brake disc 1, and extend the service life of the bushing 2 and the brake disc 1.

[0032] Specifically, the brake disc 1 has four limiting grooves 102 on its front and rear surfaces. Each of the four limiting grooves 102 is connected to the rotor groove 101 and is located on both sides of the rotor groove 101. The front and rear surfaces of the two bushings 2 are provided with limiting blocks 202. The four limiting blocks 202 correspond to the positions of the four limiting grooves 102 and are located inside the four limiting grooves 102. Inserting the limiting blocks 202 into the limiting grooves 102 can restrict the position of the bushings 2 and increase their stability.

[0033] Furthermore, each of the two bushings 2 is internally connected to abutment rods 203 via torsion springs. There are four abutment rods 203, with their ends furthest from the bushing 2 abutting against each other. The spring force of the torsion springs causes the abutment rods 203 to rotate, bringing them into contact and thus fixing the bushing 2. The ends of the two right-side abutment rods 203 furthest from the bushing 2 are movably connected to insertion rods 204. Magnetic blocks 209 are provided at the ends of the two right-side abutment rods 203 furthest from the bushing 2 and at the ends of the insertion rods 204. After the abutment rods 203 rotate, the magnetic force of the magnetic blocks 209 moves the insertion rods 204, thus fixing the two abutment rods 203. The position is restricted to prevent the abutment rod 203 from being misaligned. An ejector spring 205 is provided inside the left end of the insertion rod 204. A locking block 206 is provided at the end of the ejector spring 205 near the abutment rod 203. A roller is rotatably connected inside the locking block 206 away from the ejector spring 205. The roller can reduce the friction between the locking block 206 and the abutment rod 203, making it easier for the insertion rod 204 to move. A slot 207 is provided inside the abutment rod 203 away from the bushing 2, and the locking block 206 is positioned corresponding to the slot 207. The elastic force of the ejector spring 205 can drive the locking block 206 to move and insert the locking block 206 into the slot 207, thereby preventing the abutment rod 203 from separating.

[0034] Furthermore, two sliders 303 are slidably connected to the surface of the bridge plate 3 away from the brake disc 1. Support rods 305 are rotatably connected to the two sliders 303 away from the surface of the bridge plate 3. The support rods 305 support both sides of the bridge plate 3. When the sliders 303 move, they can move one end of the support rods 305, thereby improving the support effect of the support rods 305 on both sides of the bridge plate 3. The ends of the two support rods 305 away from the sliders 303 are rotatably connected to the inner surface of the bridge plate 3 away from the sliders 303. Four mounting blocks 301 are provided on the surface of the bridge plate 3 away from the brake disc 1. Between every two mounting blocks 301... A mounting rod 302 is provided, and two sliders 303 are slidably connected to the outer surfaces of the two mounting rods 302 respectively. The mounting rods 302 are installed by mounting blocks 301, and the sliders 303 are located on the outer surfaces of the mounting rods 302, thereby restricting the position of the sliders 303 and preventing them from shifting during movement. A return spring 304 is sleeved on the outer surface of each of the two mounting rods 302. The two return springs 304 are located between the two sliders 303 and the two mounting blocks 301 in the middle, and the two ends of the return springs 304 abut against the surfaces of the sliders 303 and the mounting blocks 301 respectively. The elastic force of the return springs 304 can drive the sliders 303 to move.

[0035] Furthermore, a rotating rod 4 is rotatably connected to the surface of the bridge plate 3 away from the brake disc 1. There are two rotating rods 4, and each end of the two rotating rods 4 is rotatably connected to a connecting rod 401. The ends of the four connecting rods 401 away from the rotating rods 4 are respectively rotatably connected to the front and rear surfaces of the two bushings 2 away from the rotating rods 4. By installing the connecting rods 4, the bushings 2 away from the rotating rods 4 can be supported, improving the stability of the bushings 2. Connecting springs 402 are provided on the front and rear sides of the two rotating rods 4 near the surface of the bushings 2. There are four connecting springs 402. The ends of the four connecting springs 402 away from the rotating rods 4 are respectively provided on the front and rear surfaces of the two sliders 303. When the bushings 2 shift away from the rotating rods 4, the elastic force of the connecting springs 402 can drive the rotating rods 4 to rotate, thereby driving the bushings 2 to move and reset through the connecting rods 401.

[0036] Working principle: The bushing 2 is placed inside the rotor slot 101. Moving the bushing 2 inserts the limiting block 202 into the limiting slot 102. During the movement of the bushing 2, the push rod 208 moves and pushes out the abutting rod 203. The force of the torsion spring drives the abutting rod 203 to rotate, causing one end of the two abutting rods 203 to abut against each other. The abutting of the two abutting rods 203 fixes the two bushings 2. The attraction of the magnetic block 209 pulls the insertion rod 204 into the abutting rod 203, thus fixing the two abutting rods 203. The force of the push-out spring 205 drives the locking block 206 to move and insert the locking block 206 into the locking slot 207. This prevents the abutment rod 203 from separating. The bridging plate 3 is placed between the two bushings 2, with both ends of the bridging plate 3 located inside the positioning grooves 201 on the surfaces of the two bushings 2. This allows the bridging plate 3 to abut the bushings 2, preventing them from falling off. During the use of the bushings 2, the spring force of the return spring 304 can drive the slider 303 to move closer to the bushings 2. The support rod 305 can support both sides of the bridging plate 3. When the bushings 2 shift away from the rotating rod 4, the spring force of the connecting spring 402 can drive the rotating rod 4 to rotate, thereby moving the bushings 2 through the connecting rod 401 to reset the bushings 2.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
