Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0026] Please see Figure 1 This application provides a braking mechanism 100, a rotating device configured with the braking mechanism 100, and a transport vehicle configured with the rotating device. In this embodiment, the transport vehicle may include a passenger car or sedan for carrying passengers, a truck or van for transporting goods, an airplane, or other means of transportation. In this embodiment, the transport vehicle includes a vehicle body and a rotating device, the rotating device being mounted on the vehicle body and capable of driving the vehicle body to travel or glide on the ground.

[0027] In this embodiment, the transport vehicle may include a land vehicle, the vehicle body of which includes a body shell for carrying passengers or loading goods. In this embodiment, the rotating device includes multiple rotating wheels, forming multiple wheel sets. Each wheel set includes a rotating axle and at least two rotating wheels, and the multiple wheel sets are mounted on the underside of the body shell. In this embodiment, the rotating device may also include a drive mechanism. At least one wheel set among the multiple wheel sets is connected to the drive mechanism, which drives the wheel sets to rotate so that the vehicle can travel on the ground. In this embodiment, the rotating device also includes a brake disc 830 and a braking mechanism 100. The brake disc 830 is fixedly mounted to the rotating wheels, for example, fixedly mounted to the hub of the rotating wheels. In this embodiment, the braking mechanism 100 is used to clamp the brake disc 830 to reduce the rotational speed of the brake disc 830 and the rotating wheels, so that the vehicle decelerates or stops. In this embodiment, the braking mechanism 100 is mounted on the transport vehicle. The braking mechanism 100 can be mounted on a non-rotating structure around the rotating wheel. For example, if the rotating wheel is rotatably mounted on the steering knuckle 840, the braking mechanism 100 can also be mounted on the steering knuckle 840, so that the braking mechanism 100 can effectively limit the rotation of the brake disc 830 and the rotating wheel. In other embodiments, the rotating wheel is rotatably mounted on a wheel hub bushing, and the braking mechanism 100 can be mounted on the wheel hub bushing.

[0028] In this embodiment, each rotating device may include multiple brake discs 830 and multiple braking mechanisms 100. At least some of the multiple rotating wheels correspond one-to-one with the multiple brake discs 830, and each brake disc 830 is fixedly mounted on a corresponding rotating wheel. In this embodiment, the multiple braking mechanisms 100 correspond one-to-one with the multiple brake discs 830, and each braking mechanism 100 is used to clamp a corresponding brake disc 830 to restrict the rotation of the corresponding brake disc 830 and the corresponding rotating wheel. With the configuration of this embodiment, the multiple sets of cooperating brake discs 830 and braking mechanisms 100 improve the braking capability of the vehicle.

[0029] In other embodiments, the transport vehicle may further include an aircraft, the aircraft body including a fuselage, which is used for carrying passengers or loading cargo. In this embodiment, the rotating device includes a plurality of rotating wheels, at least one of which is provided with a brake disc 830 and a braking mechanism 100. The braking mechanism 100 restricts the rotation of the rotating wheel by clamping the brake disc 830, so that the aircraft can stop on the apron within a preset time or a preset taxiing range.

[0030] Please see Figure 2In this embodiment, the braking mechanism 100 includes a caliper bracket 10 and a caliper body 20, with the caliper bracket 10 fixedly mounted on the transport vehicle. In this embodiment, the rotating wheel and brake disc 830 are rotatably mounted on the steering knuckle 840 about the axis of the rotating wheel. The caliper bracket 10 is fixedly mounted on the steering knuckle 840. The contours formed by the rotating wheel and brake disc 830 during rotation are approximately the same as the contours of the rotating wheel and brake disc 830 themselves. The caliper bracket 10 remains relatively stationary with respect to the contours of the rotating wheel and brake disc 830. In this embodiment, the caliper body 20 is movably mounted on the caliper bracket 10. The caliper body 20 moves relative to the caliper bracket 10 to clamp the brake disc 830, thereby reducing the travel speed of the transport vehicle or stopping the transport vehicle.

[0031] Please see Figure 1 and Figure 2 Specifically, in this embodiment, the caliper body 20 includes a mounting bracket 21, a piston, and two friction members. The mounting bracket 21 is movably mounted on the caliper bracket 10. The mounting bracket 21 includes a first mounting portion 211 and a second mounting portion 212, which are spaced apart from each other. A hydraulic chamber is provided on the side of the first mounting portion 211 facing the second mounting portion 212. The piston is movably embedded in the hydraulic chamber and is sealed to the first mounting portion 211. The piston can move relative to the first mounting portion 211 towards the second mounting portion 212. In this embodiment, the two friction members include a first friction member 231 and a second friction member 232. The first friction member 231 is disposed on the side of the piston facing the second mounting portion 212, and the second friction member 232 is disposed on the side of the second mounting portion 212 facing the first mounting portion 211, so that the two friction members are spaced apart from each other. When the braking mechanism 100 is mounted on a transport vehicle, the brake disc 830 is located between the two friction members. In this embodiment, the transport vehicle includes a hydraulic assembly (not shown in the figure), which is mounted on the vehicle body and communicates with the hydraulic chamber. The transport vehicle also includes a brake pedal, which is located in the driver's cabin. In this embodiment, the friction element may include a semi-metallic structure, a ceramic composite structure, etc.

[0032] In practical applications, the driver increases the hydraulic pressure in the hydraulic assembly by pressing the brake pedal. The oil in the hydraulic assembly flows into the hydraulic chamber, and the first friction element 231 initially abuts against the brake disc 830. The driver continues to press the brake pedal to further increase the hydraulic pressure, and the hydraulic assembly continues to supply oil into the hydraulic chamber, generating hydraulic driving force to push the piston. The piston pushes the first friction element 231, and the reaction force pushes the mounting bracket 21 to move relative to the caliper bracket 10. The first mounting part 211 moves away from the brake disc 830, while the second mounting part 212 and the second friction element 232 move towards the brake disc 830 until the second friction element 232 abuts against the brake disc 830. In this case, the first friction element 231 and the second friction element 232 abut against opposite sides of the brake disc 830 and clamp the brake disc 830. The two friction elements generate opposing torques to reduce the rotational speed of the brake disc 830 and the rotating wheel. When not braking, the distance between the two friction components and the brake disc 830 is approximately within the preset range, and the pedal travel formed when the driver presses the brake pedal is also within the preset range, thus achieving normal braking.

[0033] In this embodiment, the braking mechanism 100 further includes a reset elastic element (not shown in the figure). The reset elastic element is connected between the first mounting portion 211 and the piston. As the piston moves away from the first mounting portion 211, the reset elastic element is stretched and contains elastic deformation force. After braking ends, the driver releases the brake pedal, and the reset elastic element releases the elastic deformation force and contracts. In this embodiment, the reset elastic element has two consecutive contraction stages. In the first stage, the first friction element 231 remains pressed against the brake disc 830 under the resistance of the reset elastic element. The mounting bracket 21 moves relative to the brake disc 830, the first mounting portion 211 moves toward the brake disc 830, and the second mounting portion 212 and the second friction element 232 move away from the brake disc 830. The second friction element 232 separates from the brake disc 830. In the second stage, the mounting bracket 21 is stationary relative to the brake disc 830, while the piston moves relative to the brake disc 830, moving away from the brake disc 830 and gradually embedding itself into the piston cavity. The first friction element 231 also separates from and moves away from the brake disc 830. After the elastic deformation force in the reset elastic element is released, the first friction element 231 and the second friction element 232 are located on opposite sides of the brake disc 830 and are spaced apart from it.

[0034] When the transport vehicle travels on bumpy roads, the vibration between the conventional caliper bracket 10 and the mounting bracket 21 causes the mounting bracket 21 to move relative to the caliper bracket 10. In some cases, the first mounting part 211 and the first friction member 231 move relative to the caliper bracket 10 toward the brake disc 830, reducing the distance between the first friction member 231 and the brake disc 830 and increasing the distance between the second friction member 232 and the brake disc 830. Even when the first friction member 231 is already in contact with the brake disc 830, there is still a large distance between the second friction member 232 and the brake disc 830. The travel of the brake pedal needs to be greater than the preset travel to move the second friction member 232 to contact the brake disc 830. In other cases, the first mounting part 211 and the first friction member 231 move away from the brake disc 830 relative to the caliper bracket 10, increasing the distance between the first friction member 231 and the brake disc 830 and decreasing the distance between the second friction member 232 and the brake disc 830. In this case, the second friction member 232 will abut against the brake disc 830 before the first friction member 231, and the first friction member 231 cannot receive sufficient pressure, reducing the braking torque by 30%-50%. The driver needs to further depress the brake pedal, making the brake pedal travel greater than the preset travel, so that the two friction members can effectively cooperate with the brake disc 830 and restrict the rotation of the brake disc 830 and the rotating wheel. In addition, in this case, the deformation degree of the restoring elastic member will increase, which may cause the restoring elastic member to fail to contract or break. In this embodiment, the phenomenon of "brake pedal travel greater than the preset travel" is defined as "brake slippage".

[0035] Please see Figure 1 In this embodiment, the braking mechanism 100 further includes a buffer assembly 30, which is connected between the caliper body 20 and the caliper bracket 10. Specifically, the buffer assembly 30 is connected between the mounting bracket 21 and the caliper bracket 10. When the transport vehicle passes through a bumpy road section, the buffer assembly 30 can buffer the vibration between the caliper bracket 10 and the mounting bracket 21, preventing the mounting bracket 21 from moving too much relative to the caliper bracket 10, preventing the mounting bracket 21 from displacing too much relative to the brake disc 830, and preventing the distance between the first friction member 231 and the second friction member 232 and the brake disc 830 from being outside their respective distance ranges, thus avoiding the problem of brake slippage.

[0036] In summary, this embodiment provides a braking mechanism 100, which is used to reduce the rotational speed of the brake disc 830. The braking mechanism 100 includes a caliper bracket 10, a caliper body 20, and a buffer assembly 30. The caliper bracket 10 is fixedly mounted on the transport vehicle. The caliper body 20 is used to clamp the brake disc 830 to limit the rotation of the brake disc 830. The caliper body 20 is movably mounted on the caliper bracket 10. The buffer assembly 30 is connected between the caliper body 20 and the caliper bracket 10 so that the braking mechanism 100 has better shock resistance and can prevent the caliper body 20 from moving relative to the caliper bracket 10. In this embodiment, the caliper body 20 is relatively stable relative to the caliper bracket 10 and the brake disc 830, which can overcome large vibrations and prevent the caliper body 20 from having a large degree of free play displacement relative to the brake disc 830. This reduces the probability of brake slippage and can effectively reduce the rotational speed of the brake disc 830 to reduce the speed of the transport vehicle. It can also prevent the driver from panicking or making incorrect operations due to the thought of brake slippage while driving, thus improving the driver's driving experience.

[0037] Please see Figure 3 In this embodiment, the caliper bracket 10 is provided with a guide hole 11, which is used to store buffer solution. In this embodiment, the buffer assembly 30 includes a guide rod 31 and a buffer plug 32. One end of the guide rod 31 is connected to the caliper body 20, and the other end engages with the guide hole 11. Specifically, in this embodiment, one end of the guide rod 31 is fixedly connected to the mounting bracket 21 of the caliper body 20, and the other end is movably embedded in the guide hole 11. The buffer plug 32 is connected to the end of the guide rod 31 that extends into the guide hole 11, and the buffer plug 32 is disposed within the guide hole 11. In this embodiment, the guide hole 11 is sealed to stabilize the hydraulic pressure within the guide hole 11. The ease with which the guide rod 31 and the piston move within the guide hole 11 is reduced, which can buffer vibrations on bumpy roads and prevent the caliper body 20 from moving relative to the caliper bracket 10 under non-braking conditions, thus avoiding the problem of brake slippage.

[0038] In other embodiments, the buffer assembly 30 may include a spring (or an elastic rubber sleeve) sleeved on the guide rod 31, with its two ends abutting against the caliper bracket 10 and the caliper body 20 respectively, to prevent the caliper body 20 from moving relative to the caliper bracket 10 under vibration. In some embodiments, the buffer assembly 30 may include multiple elastic elements, such as springs, disposed between the caliper bracket 10 and the caliper body 20, with each elastic element's two ends abutting against the caliper bracket 10 and the caliper body 20 respectively, to prevent the caliper body 20 from moving relative to the caliper bracket 10 under vibration.

[0039] Please see Figure 4 and Figure 5In this embodiment, the outer peripheral wall of the buffer plug 32 is in contact with the wall of the guide hole 11. The buffer plug 32 can be in a state of being compressed by the wall of the guide hole 11 to increase the friction between the buffer plug 32 and the wall of the guide hole 11. A large external force needs to be applied to the guide rod 31 to make the buffer plug 32 move, so as to effectively buffer vibration. In this embodiment, the buffer plug 32 divides the guide hole 11 into a first space 114 and a second space 115. The buffer plug 32 is provided with a liquid passage hole 321, which is used to connect the first space 114 and the second space 115, so that the oil in the first space 114 and the second space 115 can flow interchangeably, so that the buffer plug 32 can move within the guide hole 11.

[0040] In this embodiment, the buffer plug 32 is tightly fitted around the outer periphery of the guide rod 31, preventing the buffer solution from flowing through the gap between the buffer plug 32 and the guide rod 31 into the first space 114 and the second space 115, so that the buffer solution can flow through the liquid passage 321 into the first space 114 and the second space 115. In other embodiments, the buffer plug 32 may be connected to the end of the guide rod 31. In this embodiment, the ease with which the guide rod 31 and the buffer plug 32 move within the guide hole 11 varies depending on the inner diameter of the liquid passage 321. A smaller inner diameter of the liquid passage 321 results in less ease of movement for the guide rod 31 and the buffer plug 32 within the guide hole 11, while a larger inner diameter results in greater ease of movement. The ease of movement of the guide rod 31 and the buffer plug 32 within the guide hole 11 can be adjusted by selecting buffer pistons with different inner diameters of the liquid passage 321, thus achieving different anti-vibration effects for the braking mechanism 100. This embodiment, by controlling variables, allows for adjusting the buffering effect of the buffer assembly 30 by adjusting the inner diameter of the liquid passage 321, thereby enabling the braking mechanism 100 to achieve different anti-vibration effects.

[0041] In this embodiment, the buffer plug 32 is provided with multiple fluid passage holes 321, which are arranged sequentially and at intervals around the axis of the guide rod 31. This ensures that the force on the guide rod 31 and the buffer plug 32 is relatively uniform, preventing one side of the buffer plug 32 from being excessively squeezed, and preventing the caliper body 20 from tilting relative to the caliper bracket 10, thus reducing the contact area between the two friction elements and the brake disc 830 and preventing a decrease in braking effect. In this embodiment, the axis of the guide hole 11 is approximately coincident with the axis of the guide rod 31. The caliper body 20 moves relative to the caliper bracket 10 along the axis of the guide rod 31, and the two friction elements, driven by the hydraulic assembly, also move along the axis of the guide rod 31 to move closer to or away from the brake disc 830.

[0042] Please see Figure 6In this embodiment, the braking mechanism 100 further includes a dust cover 40, which has a sleeve-like structure. The dust cover 40 is sleeved on the outer periphery of the guide rod 31. One end of the dust cover 40 is connected to the caliper bracket 10 and is arranged around the outer periphery of the guide hole 11, while the other end is sealed to the guide rod 31 to seal the guide hole 11 and prevent dust from entering the guide hole 11. In this embodiment, the dust cover 40 includes a rubber shrink sleeve or a silicone shrink sleeve so that the dust cover 40 can shrink or expand along its axial direction.

[0043] Please see Figure 6 and Figure 7 In this embodiment, the buffer assembly 30 further includes a seal 33 for sealing the guide hole 11. Specifically, the seal 33 has an annular structure, is disposed around the outer periphery of the guide rod 31 and fits tightly against the outer periphery of the guide rod 31 to prevent the buffer solution from flowing out of the guide hole 11 through the gap between the seal 33 and the guide rod 31. When the seal 33 is installed on the caliper bracket 10, the seal 33 is located between the guide rod 31 and the hole wall of the guide hole 11, and the seal 33 fits tightly against the hole wall of the guide hole 11 to prevent the buffer solution from flowing out of the guide hole 11 through the gap between the seal 33 and the hole wall of the guide hole 11, thereby sealing the guide hole 11. In this embodiment, the seal 33 includes a rubber ring or a silicone ring, etc.

[0044] In this embodiment, the guide hole 11 includes two interconnected first hole segments 111 and second hole segments 112. The inner diameter of the second hole segment 112 is larger than the inner diameter of the first hole segment 111 to form a limiting step 113. When the seal 33 is disposed on the caliper bracket 10, the seal 33 is embedded in the second hole segment 112 and abuts against the limiting step 113. The guide rod 31 passes through the seal 33 and extends to the first hole segment 111. The buffer plug 32 is disposed in the first hole segment 111, and the first hole segment 111 stores buffer fluid. In this embodiment, the limiting step 113 can restrict the movement of the seal 33 toward the first hole segment 111, making the position of the seal 33 more stable, so as to effectively seal the guide hole 11 and keep the hydraulic pressure in the first hole segment 111 constant.

[0045] This embodiment provides a braking mechanism 100, which is used to reduce the rotational speed of the brake disc 830. The braking mechanism 100 includes a caliper bracket 10, a caliper body 20, and a buffer assembly 30. The caliper bracket 10 is fixedly mounted on the transport vehicle. The caliper body 20 is used to clamp the brake disc 830 to limit the rotation of the brake disc 830. The caliper body 20 is movably mounted on the caliper bracket 10. The buffer assembly 30 is connected between the caliper body 20 and the caliper bracket 10 so that the braking mechanism 100 has better shock resistance and can prevent the caliper body 20 from moving relative to the caliper bracket 10. In this embodiment, the caliper body 20 is relatively stable relative to the caliper bracket 10 and the brake disc 830, which can overcome large vibrations and prevent the caliper body 20 from having a large degree of free play displacement relative to the brake disc 830. This reduces the probability of brake slippage and can effectively reduce the rotational speed of the brake disc 830 to reduce the speed of the transport vehicle. It can also prevent the driver from panicking or making incorrect operations due to the thought of brake slippage while driving, thus improving the driver's driving experience.
