Description

Technical Field

[0001] This invention relates to the field of brake technology, specifically to an electromechanical brake. Background Technology

[0002] A brake is a device that slows down, stops, or keeps a moving part (or moving machinery) at a stop. It is a mechanical part that stops or slows down moving parts in a machine. It is commonly known as a brake or brake. A brake is mainly composed of a frame, braking components, and operating devices. Some brakes are also equipped with automatic adjustment devices for the clearance of the braking components. However, in real life, we have found that brake pads in a brake system often wear down with continuous braking, eventually affecting the stable braking of the car and posing a safety hazard. Under normal circumstances, the need to replace brake pads is determined by three methods: checking the thickness, listening to the sound, and feeling the pressure. However, this method requires the car owner to be very sensitive and is influenced by subjective consciousness. In order to save costs, car owners generally use them as long as they can, and often judge them as still usable when checking, which leads to great safety hazards. Therefore, we propose an electromechanical brake. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0018] Please see Figure 1-13 and appendix Figure 15-16 The present invention provides a technical solution: an electro-mechanical brake, including a brake caliper 1, a brake pad 2 and a friction pad 3 and a brake disc 4 provided therewith, and also includes an electronic control unit 15, a motor 16, a torque transmission device 17, a control unit housing 18, a spiral climbing transmission device A19, a roller 20, a preload reset device 21, a spiral climbing transmission device B22, and a spiral thrust piston 23. The marking rod 5 is located on one side of the brake caliper 1 and is used by the user to observe the thickness of the friction plate 3; Adjusting sleeve 6 is set on the side of brake pad 2 near friction plate 3, and is used to control the movement of marking rod 5 according to the wear of friction plate 3; The transmission mechanism 7, located inside the brake caliper 1, is used to transmit the power given by the adjusting sleeve 6, thereby controlling the movement of the marking rod 5.

[0019] The adjusting sleeve 6 includes a fixing ring 61 disposed on the side of the brake pad 2 near the friction plate 3. The fixing ring 61 is made of the same material as the friction plate 3. Multiple slots 62 are provided inside the fixing ring 61. A sliding plate 63 is slidably disposed inside the fixing ring 61. The material of the sliding plate 63 has a higher wear resistance than that of the friction plate 3. Multiple locking blocks 64 are disposed on the outside of the sliding plate 63, and the multiple locking blocks 64 cooperate with the multiple slots 62. When the brake pad 2 drives the adjacent friction plate 3 to clamp the brake disc 4, the brake pad 2 will drive the fixing ring 61 disposed on its side to move together. When the fixing ring 61 moves, the sliding plate 63 disposed inside it will also move with the fixing ring 61. When the fixing ring 61 and the friction plate 3 are worn, the sliding plate 63 disposed inside the fixing ring 61 will be braked. The brake disc 4 presses against the brake plate 63, causing the sliding plate 63 to move along with the multiple locking blocks 64 on its outer side. When the sliding plate 63 moves along with the locking blocks 64, the locking blocks 64 will be pressed into another locking groove 62 by the brake disc 4, thus causing the position of the sliding plate 63 within the fixing ring 61 to change. When the brake pad 2 causes the fixing ring 61 to disengage from the brake disc 4, the sliding plate 63 within the fixing ring 61 will press against the first sliding rod 102 as it retracts with the brake pad 2. Under the action of the locking blocks 64 and the locking groove 62, the position of the sliding plate 63 will not change, thus allowing the first sliding rod 102 to slide within the dust cover 101. Its function is that the sliding plate 63 can move according to the change in the thickness of the friction pad 3, thereby causing the sliding plate 63 to press against the first sliding rod 102.

[0020] The transmission mechanism 7 includes an auxiliary component 8 installed in the brake caliper 1 to assist in transmitting the power provided by the adjusting sleeve 6. A rotating component 9 is provided on one side of the brake caliper 1 to control the movement and fixation of the marking rod 5.

[0021] The auxiliary component 8 includes a sliding member 10 disposed in the brake caliper 1 for receiving the power provided by the adjusting sleeve 6. A switching member 11 is disposed on one side of the brake caliper 1 for switching the direction of the power provided by the adjusting sleeve 6 and transmitting the switched power.

[0022] The sliding member 10 includes a dust cover 101 disposed on one side of the brake caliper 1. A first slide rod 102 is slidably disposed inside the dust cover 101, and a second slide rod 103 is slidably disposed inside the first slide rod 102. The end of the second slide rod 103 away from the first slide rod 102 is disposed on the inner wall of the dust cover 101. A compression spring 104 is disposed on one end of the first slide rod 102, and the end of the compression spring 104 away from the first slide rod 102 is disposed on the inner wall of the dust cover 101. When the first slide rod 102 slides inside the dust cover 101 under the action of the sliding plate 63, the end of the first slide rod 102 near the second slide rod 103 will slide on the outside of the second slide rod 103. The compression spring 104 disposed on one end of the first slide rod 102 can continuously apply a pushing force to the first slide rod 102. Its function is to prevent the position of the first slide rod 102 from changing due to vibration generated during vehicle operation.

[0023] The switching component 11 includes a switching groove 111 formed in the first slide bar 102, with multiple locking teeth 112 provided in the switching groove 111. A switching rod 113 is rotatably disposed inside the dust cover 101, and the switching rod 113 passes through the switching groove 111. A gear 114 is provided on the outside of the switching rod 113, and the gear 114 meshes with the multiple locking teeth 112. When the second slide bar 103 slides inside the dust cover 101, the multiple locking teeth 112 in the switching groove 111 will also move along with the second slide bar 103. When the locking teeth 112 move, they will cause the gear 114 that meshes with them to rotate. When the gear 114 rotates, it will drive the ratchet 121 on the outside of the switching rod 113 to rotate through the switching rod 113 at its axis. Its function is to convert the lateral power of the second slide bar 103 into rotational power, and control the movement of the marking rod 5 through the rotational force.

[0024] The rotating assembly 9 includes a positioning element 12 disposed inside the dust cover 101, which is used to fix and move the position of the marking rod 5. An observation element 13 is provided at the bottom of the dust cover 101, which is used by the user to observe the position of the marking rod 5 and thus judge the degree of use of the friction plate 3.

[0025] The positioning component 12 includes a ratchet 121 disposed outside the switching lever 113, a positioning frame 122 disposed inside the dust cover 101, a rotating shaft 123 rotatably disposed inside the positioning frame 122, a ratchet 124 disposed outside the rotating shaft 123, and the ratchet 124 engaging with the ratchet 121, a torsion spring 125 disposed outside the rotating shaft 123, a winding wheel 126 disposed outside the switching lever 113, a winding rope 127 wound around the winding wheel 126, one end of the winding rope 127 being disposed on the winding wheel 126, and the other end being disposed on the top of the marking rod 5. When the ratchet 121 rotates under the action of the switching lever 113, the ratchet 121 will spring away the ratchet 124 on one side. When the first sliding lever 102 stops sliding, the ratchet 124 will be engaged by the torsion spring 125. The ratchet 124 is locked on one side again, thus fixing its position and preventing it from springing back. When the switching lever 113 rotates, the take-up wheel 126 located on its outer side rotates with it, causing the take-up wheel 126 to wind up the take-up rope 127. When the ratchet 124 is locked on the ratchet 121, the take-up wheel 126 stops winding up the take-up rope 127. As the take-up rope 127 is being wound up by the take-up wheel 126, it pulls up the marking rod 5 at one end, causing it to slide within the fixing block 131, thus moving the marking rod 5. The purpose of this is to lock the position of the switching lever 113 through the ratchet 121 and the ratchet 124, thereby controlling the movement and stillness of the marking rod 5.

[0026] The observation element 13 includes a fixing block 131 at the bottom of the dust cover 101. A scale 132 is provided on one side of the fixing block 131. The marking rod 5 is slidably disposed in the fixing block 131. A return spring 133 is provided in the fixing block 131, and the two ends of the return spring 133 are respectively disposed at the bottom of the marking rod 5 and in the fixing block 131. When the marking rod 5 moves, the user can observe the position of the marking rod 5 through the scale 132 on one side of the fixing block 131, and thus observe the wear condition of the friction plate 3 through the marking rod 5. The return spring 133 at the bottom of the marking rod 5 can provide tension to the marking rod 5 after the marking rod 5 moves, so that the winding rope 127 is straightened, thereby making the position of the marking rod 5 more accurate. Its function is to prevent the winding rope 127 from loosening when the user observes the position of the scale 132 and the marking rod 5, so that the user cannot accurately obtain the wear degree of the friction plate 3. The electronic control unit 15 is fixed to the brake caliper 1. There are two motors 16, employing a dual-motor drive mode to provide redundancy for the braking system. Even if one motor 16 fails, the other motor 16 can continue to provide braking force. The control unit housing 18 also serves as the motor housing, housing the stator and rotor of the motor 16, further compressing the axial space. The torque transmission device 17 consists of a multi-stage gear pair and rolling bearings. The torque of the motor 16 is amplified by the torque transmission device and transmitted to the helical force amplification structure. The helical force amplification structure consists of a helical climbing transmission device A19, rollers 20, a preload reset device 21, a helical climbing transmission device B22, and a helical thrust piston 23. The rollers 20 perform pure rolling between the helical climbing transmission device A19 and the helical climbing transmission device B22. The helical climbing transmission device A19 and the helical climbing transmission device B22 are as follows... Figure 15 , Figure 16 As shown, section I of the slope meets the braking force requirements for light braking, section III meets the requirements for heavy braking such as emergency braking, and section II of the slope can achieve self-locking of the roller 20 to realize parking brake under the combined action of the elastic force provided by the pre-tightening reset device 21 and the reaction force from the friction plate 3. The helical thrust piston 23 and the helical climbing transmission device B22 are connected by a transmission thread to achieve the self-locking function.

[0027] During braking, the torque output by motor 16 is transmitted to the spiral ramp transmission device A19 via torque transmission device 17. At this time, roller 20 and the preload reset device 21 of spiral ramp transmission device B22 move in a consistent manner. Under the cooperation of the rotary transmission thread, the spiral thrust piston 23 rotates rapidly, completing the contact between friction plate 3 and brake disc 4 in a very short time, eliminating the braking gap. Afterward, roller 20 begins to move along the segmented ramp surfaces of spiral ramp transmission device A19 and spiral ramp transmission device B22, causing brake caliper 1 to deform and provide corresponding clamping force. When a smaller braking force is required, roller 20 remains on the first ramp surface. When a larger braking force is required, roller 20 enters the third ramp surface, providing a faster braking response.

[0028] When the brake is released, the motor 16 reverses its rotation. The pre-tightening reset device 21, after being pre-compressed, generates a spring force on the spiral climbing transmission device B22 to restore it to its initial position. This force moves the spiral thrust piston 23 in the opposite direction, causing the friction plate 3 to separate from the brake disc 4, thus releasing the brake. During this process, the reset force provided by the pre-tightening reset device 21 keeps the spiral climbing transmission device A19, roller 20, and spiral climbing transmission device B22 in contact. When the brake is released, the motor 16 always retracts a certain angle in the opposite direction of braking, ensuring that the gap between the friction plate 3 and the brake disc 4 remains at a specified value even as the friction plate 3 wears.

[0029] When the parking brake is applied, the roller 20 will move on the second slope. Under the combined action of the reaction force provided by the brake caliper 1 after deformation due to braking and the reset force provided by the preload reset device 21, it will maintain self-locking on the second slope to achieve the parking function.

[0030] In use, when the brake pad 2 drives the adjacent friction pad 3 to clamp the brake disc 4, the brake pad 2 will move along with the fixing ring 61 located on one side of it. When the fixing ring 61 moves, the sliding plate 63 slidably disposed within it will also move along with the fixing ring 61. When the fixing ring 61 and the friction pad 3 are worn, the sliding plate 63 slidably disposed within the fixing ring 61 will be squeezed by the brake disc 4, thereby causing the sliding plate 63 to drive the multiple locking blocks 64 on its outer side to move. When the sliding plate 63 drives the locking blocks 64 to move, the locking blocks 64 will be squeezed into another locking groove 62 under the pressure of the brake disc 4, thereby changing the position of the sliding plate 63 within the fixing ring 61. When the brake pad 2 drives the fixing ring 61 to disengage from clamping the brake disc 4... Subsequently, the sliding plate 63 inside the retaining ring 61 will press the first sliding rod 102 when it retracts with the brake pad 2. Under the action of the locking block 64 and the locking groove 62, the position of the sliding plate 63 will not change, thus allowing the first sliding rod 102 to slide inside the dust cover 101. When the first sliding rod 102 slides inside the dust cover 101 under the action of the sliding plate 63, the end of the first sliding rod 102 near the second sliding rod 103 will slide outside the second sliding rod 103. The compression spring 104 provided at one end of the first sliding rod 102 can continuously apply a pushing force to the first sliding rod 102. Its function is to prevent the position of the first sliding rod 102 from changing due to vibrations generated during vehicle operation. When the second sliding rod 103 slides inside the dust cover 101... When the first slide bar 102 is in the first position, the multiple locking teeth 112 in the switching groove 111 will also move together with the second slide bar 103. When the locking teeth 112 move, they will cause the gear 114 meshing with them to rotate. When the gear 114 rotates, it will drive the ratchet 121 on the outside of the switching bar 113 to rotate together through the switching bar 113 at its axis. When the ratchet 121 rotates under the action of the switching bar 113, the ratchet 124 on one side will be disengaged. When the first slide bar 102 stops sliding, the ratchet 124 will be locked again on one side of the ratchet 124 under the action of the torsion spring 125, thus fixing the position of the ratchet 124 and preventing the ratchet 124 from rebounding. When the switching bar 113 rotates, the winding wheel 126 on its outside will... The winding wheel 126 rotates together with the switching lever 113, causing it to wind the winding rope 127. When the ratchet 124 engages with the ratchet 121, the winding wheel 126 stops winding the rope 127. As the rope 127 is wound by the winding wheel 126, it pulls up the marking rod 5 at one end, causing it to slide within the fixing block 131 and move. Once the marking rod 5 has moved, the user can observe its position using the scale 132 on one side of the fixing block 131, thus observing the wear of the friction plate 3. The return spring 133 at the bottom of the marking rod 5 provides tension after it moves, straightening the winding rope 127.This makes the position of marker 5 more accurate. Example 2

[0031] Please see Figure 14 The present invention provides a technical solution: Unlike Embodiment 1, the sliding plate 63 is rotatably provided with multiple balls 14 on the side near the friction plate 3. When the brake pad 2 drives the fixing ring 61 to squeeze the brake disc 4, the sliding plate 63 inside the fixing ring 61 will not be worn, thereby avoiding the impact on the service life of the sliding plate 63 due to long-term wear and affecting the user's observation of the wear degree of the friction plate 3. Its function is to reduce the friction between the sliding plate 63 and the brake disc 4.
