Description

Technical Field

[0001] This invention relates to the field of automotive braking systems, and more specifically to a quick-release anti-loosening brake disc. Background Technology

[0002] The brake disc is a key component of a car's braking system. When the brake pedal is pressed, the piston inside the master cylinder is pushed, building pressure in the brake fluid lines. This pressure is transmitted via brake fluid to the pistons in the brake calipers. The pistons in the brake calipers then push the brake pads to clamp the brake disc, causing friction between the brake pads and the brake disc to reduce wheel speed and thus slow down or stop the car. For example:

[0003] The Chinese utility model patent for a carbon-ceramic brake disc, with publication number CN113357296B, uses a structure consisting of a movable plate, a fixed rod, and a spring to fix the nut, preventing it from rotating during vehicle operation and thus preventing the brake disc from detaching from the drive shaft. Furthermore, a limiting rod is added inside the brake disc to further limit the screw, effectively preventing the brake disc from detaching from the drive shaft. However, its drawback is:

[0004] The process of removing and installing brake discs requires removing and installing nuts one by one, which makes the process of removing and installing brake discs quite inconvenient. Summary of the Invention

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0061] The quick-release anti-loosening brake disc provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0062] Example 1:

[0063] like Figures 1 to 4As shown, this application embodiment provides a quick-release anti-loosening brake disc, including a drive shaft 1, a brake disc 2, and a disassembly and assembly mechanism 3. The disassembly and assembly mechanism 3 includes a disc body 31, which is fixed to the outer end of the drive shaft 1 and is inserted into the brake disc 2 through a plurality of inserts 32; a pair of slots 33, symmetrically arranged on the surface of the brake disc 2 and communicating with the inner ring of the brake disc 2; and an insertion unit 4, which includes a pair of flipping blocks 41 for engaging with the pair of slots 33, and a control device 42 for controlling whether the pair of flipping blocks 41 are flipped.

[0064] The insertion unit 4 also includes a plug 43, which is fixed on the outer end face of the drive shaft 1 and is inserted into the inner ring of the brake disc 2; a transmission cavity 44, which extends from the outer end face of the plug 43 into the drive shaft 1; a pair of side grooves 45, which are symmetrically arranged on the periphery of the plug 43 and communicate with the transmission cavity 44; a pair of flipping blocks 41 are installed in the corresponding side grooves 45 through hinges; and a control device 42 is movably installed in the transmission cavity 44.

[0065] The flipping block 41 includes a fan-shaped flipping body 411, which is movably mounted on the inner end of the side groove 45 via a pivot at its right angle; a mounting groove 412, which is located on the inner side of the fan-shaped flipping body 411; and a torsion spring 413, which is sleeved on the pivot and extends outward at both ends, respectively abutting against the inner side wall of the mounting groove 412 and the inner end wall of the side groove 45.

[0066] Furthermore, the flipping block 41 includes a fan-shaped flipping body 411, which is movably mounted on the inner end of the side groove 45 via a pivot at its right angle; a mounting groove 412, which is disposed on the inner side of the fan-shaped flipping body 411; and a torsion spring 413, which is sleeved on the pivot and extends outward at both ends, respectively abutting against the inner side wall of the mounting groove 412 and the inner end wall of the side groove 45.

[0067] In this embodiment of the application, due to the above-described structure, when installing the brake disc 2, its inner ring is inserted into the insert post 43 and pressed towards the drive shaft 1. Each insert block 32 on the disc body 31 is inserted into the slot 313 on the brake disc 2. A pair of slots 33 are positioned opposite a pair of fan-shaped rotating bodies 411. Then, the slot-shaped control device 42 causes each fan-shaped rotating body 411 to rotate around the axis of rotation into the slot 33 until the side with the mounting groove 412 is pressed against the inner end of the slot 33, and the other side wall of the fan-shaped rotating body 411 is pressed against the control device 42. Each torsion spring 413 deforms and stores elastic potential energy, thus completing the installation of the brake disc 2.

[0068] When disassembling the brake disc 2, the operating control device 42 moves away from each sector-shaped flipping body 411, and each torsion spring 413 releases its elastic potential energy, pushing each sector-shaped flipping body 411 to flip around the corresponding axis and disengage from the corresponding slot 33. Then, the brake disc 2 can be pulled away from the drive shaft 1 until it disengages from the insert 43, thus completing the disassembly of the brake disc 2.

[0069] Example 2:

[0070] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the control device 42 includes a floating shell 421, which is slidably installed in the transmission cavity 44, with its inner end closed and a return spring 422 provided between it and the inner end of the transmission cavity 44; a pair of spiral grooves 423, which are provided on the peripheral wall of the transmission cavity 44, each with a deep groove 424 at its end; and a pair of floating engaging parts 5, which are movably installed on the peripheral wall of the floating shell 421, slidingly engaging with each spiral groove 423, and can be inserted into the corresponding deep groove 424. The longitudinal cross-section of the inner cavity of the floating shell 421 is hexagonal.

[0071] Furthermore, the floating engagement member 5 includes an insertion hole 51, which is disposed on the side wall of the floating shell 421; a sliding block 52, which is slidably installed in the insertion hole 51, with a transverse groove 53 at its inner end; an inner groove 54, which is disposed in the inner cavity of the floating shell 421; and a flipping rod 55, the middle part of which is movably installed in the inner groove 54 through a hinge, one end of which is driven and engaged with the transverse groove 53 through a transmission block, and the other end is provided with an elastic element 56 between it and the bottom surface of the inner groove 54.

[0072] In this embodiment of the application, due to the above-described structure, when the brake disc 2 needs to be disassembled, an Allen wrench is inserted into the inner end of the floating shell 421. During the process, the Allen wrench and the end of each rotating rod 55 away from the insertion hole 51 contact the Allen wrench, pushing each rotating rod 55 to rotate around the corresponding hinge axis, causing the transmission block at that end of each rotating rod 55 to slide in the corresponding transverse groove 53, while simultaneously pulling each sliding block 52 to slide into the inner cavity of the floating shell 421. When each rotating rod 55 is fully inserted into the corresponding inner groove 54, the outer end of each sliding block 52 also disengages from the deep groove 424 at the outer end of the corresponding spiral groove 423. Then, the Allen wrench is rotated, causing the floating shell 421 to rotate, and each sliding block 52 slides from the outer end of the corresponding spiral groove 423 to the inner end of the spiral groove 423. During this process, the floating shell 421 slides towards the inner end of the transmission cavity 44. When each sliding block 52 is in contact with the corresponding... Corresponding to the deep groove 424 at the inner end of the spiral groove 423, while maintaining the angle of the Allen wrench, pull it out along the axial direction of the drive shaft 1 toward the inner cavity of the floating shell 421 until the Allen wrench disengages from each flipping rod 55. Each elastic element 56 (which can be an air bladder, spring, or rubber column) releases its elastic potential energy, pushing each flipping rod 55 to flip around the corresponding hinge axis. One end extends into the inner cavity of the corresponding floating shell 421, and the other end moves into the insertion hole 51 along with the corresponding transmission block. At the same time, each transmission block slides in the corresponding transverse groove 53 and pushes each sliding block 52 into the deep groove 424 at the inner end of the corresponding spiral groove 423. At this time, the floating shell 421 disengages from the contact with each sector-shaped flipping body 411. Under the action of the corresponding torsion spring 413, each sector-shaped flipping body 411 disengages from the corresponding slot 33. It is only necessary to pull the brake disc 2 away from the drive shaft 1 to remove it from the insertion post 43.

[0073] When installing the brake disc 2, its inner ring is fitted onto the insert 43 and pressed towards the disc body 31 until the inner surface of the brake disc 2 abuts against the adjacent surface of the disc body 31, and each fan-shaped rotating body 411 corresponds to the corresponding slot 33. Then, an Allen wrench is inserted into the inner end of the floating shell 421. During the process, the Allen wrench and the end of each rotating rod 55 away from the insert 51 contact the Allen wrench, pushing each rotating rod 55 to rotate around the corresponding hinge axis, causing the transmission block at that end of each rotating rod 55 to slide in the corresponding transverse groove 53, while simultaneously pulling each sliding block 52 to slide into the inner cavity of the floating shell 421. After each rotating rod 55 is fully inserted into the corresponding inner groove 54, the outer end of each sliding block 52 also disengages from the deep groove 424 at the inner end of the corresponding spiral groove 423, and then rotates ( Alternatively, without rotating the Allen wrench, the floating shell 421 is rotated, and each sliding block 52 slides to the outer end of the corresponding spiral groove 423. At the same time, the return spring 422 releases its elastic potential energy, which in turn pushes the floating shell 421 to slide out of the transmission cavity 44. During the sliding process of the floating shell 421 to the outside of the transmission cavity 44, it contacts the side plate of each sector-shaped flipping body 411 that does not have the mounting groove 412, and pushes each sector-shaped flipping plate to flip around the corresponding rotating shaft until it is inserted into the corresponding slot 33. Each torsion spring 413 deforms and stores elastic potential energy. Then the floating shell 421 continues to slide out of the transmission cavity 44 until the side wall of each sector-shaped flipping plate that does not have the mounting groove 412 contacts the outer wall of the floating shell 421, thus completing the installation of the brake disc 2 and locking each sector-shaped flipping plate.

[0074] Example 3:

[0075] like Figures 1 to 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the disc body 31 includes a fixed disc 311, which is fixed on the outer peripheral wall of the transmission shaft 1; a movable ring 312, which is sleeved on the outer peripheral wall of the transmission shaft 1; a rotation separation mechanism 6, which is used to rotate the movable ring 312 and the fixed disc 311 to separate them; each insertion post 43 is distributed circumferentially on the outward surface of the movable ring 312; and the brake disc 2 is provided with a plurality of slots 313.

[0076] Furthermore, the rotating separation mechanism 6 includes a plurality of arc-shaped grooves 312, which are spaced apart circumferentially on the surface of the fixed disk 311; a plurality of arc-shaped inserts 62, which are spaced apart circumferentially on the surface of the movable ring 312; a plurality of insertion holes 63, which are disposed in the arc-shaped inserts 62; and a plurality of insert rods 64, one end of which is fixed to one end of the corresponding arc-shaped groove 61, and the other end is slidably inserted into the corresponding insertion hole 63 and has an inner spring 65.

[0077] Preferably, both the arc-shaped groove 61 and the arc-shaped insert 62 are triangular, the insertion hole 51 is located on the shorter side wall of the bottom of the arc-shaped insert 62, and the end of the insertion rod 64 is fixed on the shorter side wall of the arc-shaped groove 61. The arc-shaped groove 61, the arc-shaped insert 62, the slot 313 and the insertion rod 64 are all spirally upward arc-shaped and concentric with the axis of the drive shaft 1.

[0078] In this embodiment of the application, due to the above-described structure, when installing the brake disc 2, the inserts 43 on it are first inserted into the slots 313 on the movable ring 312. Then, the brake disc 2 is rotated so that the arc-shaped inserts 62 are inserted into the corresponding arc-shaped grooves 61 and the inserts 64 are inserted into the corresponding insertion holes 63. The inner springs 65 are compressed and store elastic potential energy until the movable ring 312 and the adjacent surfaces of the fixed disc 311 are in contact. At this time, the slots 33 correspond to the fan-shaped rotating bodies 411. The floating shell 421 pushes the fan-shaped rotating bodies 411 to engage with the corresponding slots 33 and the side wall of each fan-shaped rotating body 411 abuts against the outer wall of the floating shell 421. Then, the brake disc 2 is released, and the inner springs 65 release elastic potential energy and apply pressure to the inserts 64. These pressures are finally applied to the movable ring 312, causing the movable ring 312 to press against the brake disc 2, so that each fan-shaped rotating body 411 is tightly engaged with the corresponding slot 33.

[0079] When each sector-shaped flipper 411 disengages from its corresponding slot 33, each inner spring 65 releases its elastic potential energy, pushing each insert rod 64 to slide outwards towards its corresponding slot 313. Each arc-shaped insert 62 also spirals away from each arc-shaped slot 61 along the axis of the drive shaft 1. The movable ring 312 moves away from the fixed disc 311, assisting in pushing the brake disc 2 outwards, making it easier for staff to remove the brake disc 2.

[0080] Example 4:

[0081] like Figures 1 to 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes a pair of floating grooves 71, symmetrically arranged on the surface of the fixed disk 311 facing the movable ring 312; a pair of floating rods 72, which are floatingly inserted into the floating grooves 71 by means of floating springs 73, with one end abutting against the surface of the movable ring 312, and the other end extending away from the movable ring 312 and passing through the fixed disk 311; and a pair of unlocking members 8, which are respectively floatingly inserted into the side wall of the transmission shaft 1, with one end connected to the corresponding floating rod 72 by means of a swing arm 74, and the other end extending into the deep groove 424 at the inner end of each spiral groove 423.

[0082] Furthermore, the unlocking component 8 includes a countersunk hole 81, which is disposed on the inner wall of the drive shaft 1 and communicates with the deep groove 424 at the inner end of the corresponding spiral groove 423; a bushing 82, which is fixed in the countersunk hole 81 and has its bottom end through; and an unlocking rod 83, which is slidably inserted in the bushing 82, with a push block 84 fixed at its bottom end that can extend into the deep groove 424, and its top end hinged to the end of the swing arm 74 away from the floating rod 72.

[0083] In this embodiment of the application, due to the above-described structure, when the movable ring 312 abuts against the adjacent end face of the fixed plate 311, it pushes each floating rod 72 to move away from the direction of movement. The corresponding swing arm 74 pushes the corresponding unlocking rod 83, causing the push block 84 at its end to extend into the deep groove 424 at the inner end of each spiral groove 423. This pushes out each sliding block 52 located in the deep groove 424 at the inner end of each spiral groove 423. The return spring 422 releases its elastic potential energy, pushing the floating shell 421 to slide out of the transmission cavity 44, thus pushing each flipping block 41 to flip and engage with the corresponding... The locking slot 33 engages, eliminating the need to insert an Allen wrench into the transmission housing cavity again during brake disc 2 installation. During disassembly, as the movable ring 312 moves away from the fixed disc 311, each floating spring 73 releases its elastic potential energy. Before each sliding block 52 moves to correspond with the inner deep groove 424 of each spiral groove 423, the push block 84 at the end of each unlocking rod 83 has already disengaged from the inner deep groove 424 of each spiral groove 423. During brake disc 2 disassembly, each unlocking rod 83 will not obstruct the engagement of each sliding block 52 with the inner deep groove 424 of each spiral groove 423.
