Abstract
Description
Technical Field
[0001] This utility model relates to the field of brakes, and more particularly to a vertically structured pneumatic disc brake. Background Technology
[0002] Currently, most pneumatic disc brake drive mechanisms on the market are installed in a horizontal or nearly horizontal direction, that is, parallel to the braking direction. A small number of drive mechanisms are installed in a vertical direction. The most common solution on the market is to install a converter on the mounting surface of the horizontal pneumatic disc brake drive mechanism to change the mounting surface and achieve vertical installation.
[0003] In the prior art, Zhejiang Wan'an Technology Co., Ltd.'s patent 201210264523.8 discloses that "the input port and output port are perpendicular. After testing the converter of this invention, the air pressure disc brake can be used in models with compact structure where the air chamber or spring brake chamber cannot be installed horizontally with the axle. This converter changes the installation position of the air chamber or spring brake chamber, solving the space problem." This solution is a split structure, adding a converter to achieve vertical installation.
[0004] This type of split structure, requiring the addition of a converter, is complex to assemble, difficult to seal, and increases overall weight and cost. To address this issue, Wuhan Yuanfeng Auto Parts Co., Ltd. designed an integrated structure. Patent 201720583814.1, "An Integrated Radial Chamber Disc Brake Caliper Body," discloses a caliper body comprising a first chamber accommodating the brake disc and a second chamber accommodating the rotating shaft mechanism. The first and second chambers are connected, and the upper and lower surfaces of the second chamber are symmetrically provided with reference seat guide surfaces, etc. This integrated radial chamber disc brake caliper body is a one-piece molded structure, reducing the bolt connection between the arched back portion and the accommodating cavity in existing split caliper bodies, avoiding assembly and machining between the arched back portion and the accommodating cavity, and improving the overall rigidity and strength of the caliper body. Simultaneously, four reference seat guide surfaces are machined inside the second chamber accommodating the rotating shaft mechanism using a disc cutter, a simple and stable machining process that achieves the limiting function of the reference seat in the rotating shaft mechanism, restricting the runout of the reference seat, making the braking force smooth and consistent, extending the life of the rotating shaft mechanism, and improving friction efficiency.
[0005] Currently, the commonly used structure is a split structure, which has relatively many joints between the various parts, all of which require precision machining. Assembling the various parts involves a large number of bolt connections and sealing issues, resulting in relatively heavy weight and complex assembly. This structure adopts an integral design, but it requires the cutting tool to penetrate deep into the second chamber for machining, which requires angle head machining, resulting in low efficiency. At the same time, it uses a non-standard reference seat guide surface, making assembly difficult and costly. In addition, because the force is perpendicular to the entire large plane, it causes stress concentration and large deformation. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides a vertically structured pneumatic disc brake.
[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0008] A vertically structured pneumatic disc brake includes a caliper cover portion and a braking portion, wherein the caliper cover portion and the braking portion are integrally formed.
[0009] The clamp cover portion has an equipment cavity with an opening, and the pressure arm assembly is installed in the cavity. The clamp cover portion includes a main body portion connected to the braking portion and a pressure arm portion extending to the other end of the main body portion. The pressure arm portion is located above the main body portion. The cavity in the pressure arm portion is used to install the arm body of the pressure arm assembly, and the cavity in the main body portion is used to install the rotating part of the pressure arm assembly.
[0010] The equipment chamber is connected to the braking part through an opening. A support baffle is detachably installed at the opening of the equipment chamber. The pressure arm assembly is installed in the equipment chamber and its lower end is supported by the support baffle. The support baffle has a hole structure for acting on the friction plate of the drive assembly. The braking part is equipped with a friction plate, and the drive assembly extends from the hole structure and is connected to the friction plate.
[0011] Preferably, the pressure arm assembly includes an arm body and a rotating part formed at the end of the arm body. The rotating part includes at least an upper first arcuate surface for rotational support and a lower arcuate groove for cooperating with a rotating shaft. The axis of the first arcuate surface and the axis of the arcuate groove are parallel but not on the same vertical plane. The rotating part forms a cam structure relative to the arcuate groove. One side of the rotating part has a rocker arm. The rotation of the rotating part drives the rocker arm to swing back and forth. The assembly also includes a gap adjustment mechanism with a drive groove. The rocker arm is limited in the drive groove. During the swinging process, the rocker arm drives the drive groove to rotate and slides up and down in the drive groove.
[0012] Preferably, the gap adjustment mechanism includes a support base with a mounting platform located in the middle, an active mechanism located on one side of the fixed base, and a driven mechanism on the other side.
[0013] The active mechanism includes an outer sleeve-shaped first rotating sleeve, with a first drive rod connected to the inner thread of the first rotating sleeve. The axial degree of freedom of the first rotating sleeve is restricted by the support base and the clamp cover part through the bearing component. The first rotating sleeve is connected to a transmission sleeve, which is a fixed connection structure with the first rotating sleeve and is arranged on the same axis. The drive groove is opened along the axial direction of the transmission sleeve. The first rotating sleeve is connected to the driven mechanism through the transmission mechanism to drive the driven mechanism to move synchronously.
[0014] Preferably, the support base forms a mounting platform in the middle for mounting the rotating part. The upper surface of the mounting platform is provided with an arc-shaped rotating groove for mounting the rotating shaft. The support base forms a first mounting channel for mounting the active mechanism and a second mounting channel for mounting the driven mechanism on the left and right sides of the mounting platform, respectively. The axes of the first mounting channel and the second mounting channel are parallel to each other and perpendicular to the axis of the rotating groove. Limiting brackets are fixedly installed on the upper surfaces of the first and second mounting channels. The limiting brackets are located at both ends of the rotating groove. The rotating shaft is installed in the rotating groove and its two ends are fixed in the limiting brackets.
[0015] Preferably, the driven mechanism includes a second drive rod and a second rotating sleeve sleeved outside the second drive rod. The second rotating sleeve and the second drive rod are threadedly connected. A coaxial first toothed ring is fixed to the outer side of the lower end of the first rotating sleeve. A second toothed ring coaxially arranged with the lower end of the second rotating sleeve is fixed to the outer side of the first rotating sleeve. The transmission mechanism is a third toothed ring. The first toothed ring and the second toothed ring achieve transmission by meshing with the third toothed ring.
[0016] Preferably, the transmission ratio between the first gear ring and the third gear ring is the same as the transmission ratio between the second gear ring and the third gear ring. The axial degree of freedom of the second rotating sleeve is restricted. When the first rotating sleeve and the second rotating sleeve rotate, one end of the first driving rod and the second driving rod are restricted from rotating. The rotation of the first rotating sleeve and the second rotating sleeve drives the first driving rod and the second driving rod to move along the axial direction.
[0017] Preferably, the lower end faces of the first and second drive rods are provided with coaxial drive columns and limiting protrusions around the drive columns. A push plate is provided below the support baffle. There are two connecting holes, which are used to adapt to the drive columns of the first and second drive rods respectively. The drive columns are inserted into the connecting holes. The edge of the connecting holes is provided with limiting grooves. The limiting protrusions are inserted into the limiting grooves. At least part of the limiting protrusions are always in the limiting grooves. When braking, the movement of the first and second drive rods drives the push plate to move synchronously.
[0018] Preferably, an opening is provided on one side of the main body, and a support platform is provided at the upper end of the chamber of the main body. An arc-shaped opening for processing is provided on the support platform, and the first arc-shaped surface is installed in the arc-shaped opening through a bearing. The chamber of the pressure arm part passes through the support platform.
[0019] Preferably, the support plate is fixedly mounted on the end face where the opening of the clamp cover chamber is located by screws.
[0020] This solution also provides a vehicle equipped with one of the aforementioned vertically structured air disc brakes.
[0021] Through the above technical solutions, the present invention has the following technical effects:
[0022] This invention designs the clamp body structure of a pneumatic disc brake, achieving a lightweight, integral clamp body structure. It also accommodates vertical installation of the drive mechanism, offers ample space, and is unconstrained by assembly limitations. The innovative external machining method allows for the formation of a high-precision arc-shaped surface within the clamp body to mate with the semi-circular bearing, significantly reducing machining costs and increasing efficiency compared to structures using angled heads. Furthermore, the assembly utilizes the semi-circular bearing for positioning, and the increased contact area reduces contact force and disperses stress on the top surface of the second assembly cavity, resulting in better overall structural strength. This positioning prevents the pressure arm from shifting, improving braking efficiency. The clamp body is easy to clamp and position, allowing all machining operations to be completed in a single setup on a machining center, ensuring precise positioning of all machined parts. This clamp body structure also facilitates the assembly of pneumatic disc brake components. After the semi-circular bearing is installed, the pressure arm assembly is simple to assemble and automatically returns to its original position. The adjustment mechanism assembly can also be assembled simply by placing it in, greatly simplifying the assembly of this part of the structure.
[0023] Furthermore, the pneumatic disc brake in this design features simple assembly of its components, with ample space for assembly, resulting in higher efficiency. Simultaneously, the assembly precision between all components is reliable, the adjustment mechanism is stable with sufficient stroke, the caliper slides smoothly, the brake pads move up and down smoothly, and the return is rapid and reliable. Additionally, the caliper's contact surface is an arc, not perpendicular to a large flat surface, thus preventing excessive load on the top surface of the second assembly cavity of the caliper, extending its service life and reducing the failure rate.

Detailed Implementation
[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0036] Example 1
[0037] A vertically structured pneumatic disc brake includes a caliper body, which comprises a caliper cover portion 1 and a braking portion 2, both of which are integrally molded. Therefore, the external caliper body in this design is directly cast in one piece, offering advantages such as high strength and fewer parts. The internally installed components are modularly assembled, providing advantages such as convenient installation and ease of use with tooling fixtures.
[0038] In this design, the clamp cover portion 1 has an open equipment cavity 3. The pressure arm assembly is installed in the cavity. Since it is a vertical structure, it requires a protruding structure as the installation space for the pressure arm. The structure of the clamp cover portion 1 is as follows: the clamp cover portion 1 includes a main body portion 4 connected to the braking portion 2 and a pressure arm portion 41 extending to the other end of the main body portion 4. The pressure arm portion 41 is located above the main body portion 4. The cavity inside the pressure arm portion 41 is used to install the arm body 5 of the pressure arm assembly. The cavity inside the main body portion 4 is used to install the rotating part 6 of the pressure arm assembly. The cavity of the main body portion 4 is approximately rectangular.
[0039] In this embodiment, the equipment cavity 3 is connected to the braking part 2 through an opening. A support baffle 7 is detachably installed at the opening of the equipment cavity 3, forming a closed and complete space inside the equipment cavity. The pressure arm assembly is installed in the equipment cavity 3 and its lower end is supported by the support baffle 7. In this embodiment, the support is indirect. Since braking is required, the support baffle 7 needs to have an opening for connecting with the friction plate in the space of the braking part 2. Therefore, the support baffle 7 has a perforated structure 8 for acting on the friction plate extending from the drive assembly. The braking part 2 is equipped with a friction plate, and the drive assembly extends from the perforated structure 8 and connects to the friction plate.
[0040] In this embodiment, the pressure arm assembly includes an arm body 5 and a rotating part 6 formed at the end of the arm body 5, wherein the arm body 5 and the rotating part 6 are an integral structure. The rotating part 6 includes at least an upper first arcuate surface 9 for rotational support and an arcuate groove 10 for cooperating with a rotating shaft 11 at the lower part. The first arcuate surface 9 serves as a support surface for rotation. The axis of the first arcuate surface 9 is parallel to the axis of the arcuate groove 10 but not on the same vertical plane. The rotating part 6 forms a cam structure relative to the arcuate groove 10. One side of the rotating part 6 has a rocker arm 12. The rotation of the rotating part 6 drives the rocker arm 12 to swing back and forth. It also includes a gap adjustment mechanism 13. The gap adjustment mechanism 13 has a drive groove 14. The rocker arm 12 is limited in the drive groove 14. During the swinging process, the rocker arm 12 drives the drive groove 14 to rotate and slide up and down in the drive groove 14.
[0041] In this embodiment, the gap adjustment mechanism 13 includes a support base 15, a mounting platform 16 located in the middle, an active mechanism 17 located on one side of the fixed base, and a driven mechanism 20 on the other side; wherein the active structure is driven by the pressure arm assembly, and the driven mechanism 20 is driven to rotate through the transmission assembly.
[0042] In this embodiment, the active mechanism 17 and the driven mechanism 20 are mounted on the support base 15, and the pressure arm assembly is mounted on the support base 15 between the active mechanism 17 and the driven mechanism 20. A torsion spring structure (not shown) is provided on the pressure arm assembly or the active mechanism 17 for return to its original position after braking is released. The active mechanism 17 includes a sleeve-shaped first rotating sleeve 21, with a first drive rod 23 internally threadedly connected to it. The axial freedom of the first rotating sleeve 21 is restricted by the support base 15 and the clamp cover portion 1 via bearing components. The first rotating sleeve 21 is connected to a transmission sleeve, which is fixedly connected to the first rotating sleeve 21 and coaxially arranged. A drive groove 14 is formed along the axial direction of the transmission sleeve. The first rotating sleeve 21 is connected to the driven mechanism 20 via a transmission mechanism, driving the driven mechanism 20 to move synchronously.
[0043] In this embodiment, a mounting platform 16 for mounting the rotating part 6 is formed in the middle of the support base 15. The upper end surface of the mounting platform 16 is provided with an arc-shaped rotating groove for mounting the rotating shaft 11. The support base 15 has a first mounting channel 25 for mounting the active mechanism 17 and a second mounting channel 26 for mounting the driven mechanism 20 on the left and right sides of the mounting platform 16, respectively. The axis of the first mounting channel 25 and the axis of the second mounting channel 26 are parallel to each other and perpendicular to the axis of the rotating groove. Limiting brackets 27 are fixedly installed on the upper end surfaces of the first mounting channel 25 and the second mounting channel 26. The limiting brackets 27 are located at both ends of the rotating groove. The rotating shaft is installed in the rotating groove and both ends are fixed in the limiting brackets 27.
[0044] In this embodiment, the driven mechanism 20 includes a second drive rod 24 and a second rotating sleeve 22 sleeved outside the second drive rod 24. The second rotating sleeve 22 and the second drive rod 24 are threadedly connected. A coaxial first toothed ring 28 is fixed to the outer side of the lower end of the first rotating sleeve 21, and a second toothed ring 29 coaxially arranged with it is fixed to the outer side of the lower end of the second rotating sleeve 22. The transmission mechanism is a third toothed ring 30. The first toothed ring 28 and the second toothed ring 29 achieve transmission by meshing with the third toothed ring 30. In order to ensure that the driving mechanism 17 and the driven mechanism 20 simultaneously push the friction plate, the transmission ratio of the first toothed ring 28 and the third toothed ring 30 is the same as the transmission ratio of the second toothed ring 29 and the third toothed ring 30. The axial degree of freedom of the second rotating sleeve 22 is restricted. When the first rotating sleeve 21 and the second rotating sleeve 22 rotate, one end of the first drive rod 23 and the second drive rod 24 is restricted from rotating. The rotation of the first rotating sleeve 21 and the second rotating sleeve 22 drives the first drive rod 23 and the second drive rod 24 to move along the axial direction.
[0045] In this embodiment, the lower end faces of the first drive rod 23 and the second drive rod 24 are provided with coaxial drive posts 31 and limiting protrusions 32 arranged around the drive posts 31. A push plate 55 is provided below the support baffle 7. There are two connecting holes 33, which are respectively used to adapt to the drive posts 31 of the first drive rod 23 and the drive posts 31 of the second drive rod 24. The drive posts 31 are inserted into the connecting holes 33. The edge of the connecting holes 33 is provided with a limiting groove 34. The limiting protrusions 32 are inserted into the limiting grooves 34, and at least part of the limiting protrusions 32 are always in the limiting grooves 34. During braking, the movement of the first drive rod 23 and the second drive rod 24 drives the push plate 55 to move synchronously. Therefore, when the first rotating sleeve 21 and the second rotating sleeve 22 drive the first drive rod 23 and the second drive rod 24 to rotate, the first drive rod 23 and the second drive rod 24 will not rotate due to the limiting structure at their lower ends. Instead, they will undergo axial displacement, thereby achieving the purpose of pushing the friction plate for braking.
[0046] In this embodiment, an opening 35 is provided on one side of the main body 4, and a support platform 36 is provided at the upper end of the cavity of the main body 4. An arc-shaped opening 37 is provided on the support platform 36 for processing through the opening 35. The first arc-shaped surface 9 is installed in the arc-shaped opening 37 through a bearing, and the cavity of the pressure arm part 41 passes through the support platform 36.
[0047] In this design, the support plate is fixedly mounted on the end face where the opening of the clamp cover chamber is located by screws.
[0048] The brake clearance adjustment process is as follows:
[0049] The pressure arm portion 41 of the clamp cover portion 1 has a hole through which external force can be applied to the pressure arm. During braking, pressing the pressure arm assembly causes the rotating portion 6 of the pressure arm assembly, which is a cam structure, to press down the support base under the action of the rotating portion. As a result, the pressure arm pushes the support base 15 downward, causing the drive rod to contact the friction plate and achieve braking. The return spring 50 is used to limit the maximum braking clearance of the braking mechanism.
[0050] When the friction pads are worn significantly and the braking clearance exceeds the design value, the reduced braking clearance caused by the deformation of the return spring cannot meet the braking requirements, necessitating clearance adjustment. Specifically: Continuing to push the pressure arm causes the rotating part 6 to rotate against the arc-shaped groove 10. The rocker arm of the pressure arm also rotates synchronously, driving the drive groove to rotate as well. Due to the presence of a torsion spring and a compression spring on the drive groove, the first rotating sleeve rotates, which in turn drives the second rotating sleeve to adjust synchronously via a gear pair, generating displacement. Since the first and second drive rods cannot rotate, the resulting displacement pushes the first and second drive rods, along with the push plate, towards the braking center, thus adjusting the clearance. When the external force is removed, the return spring drives the pressure arm back to its original position. The rocker arm rotates with the pressure arm, causing the drive groove to rotate back to its initial position. At this point, the torsion spring is in a released state and will not cause the first rotating sleeve to rotate, thus achieving clearance adjustment.
[0051] This invention designs the clamp body structure of a pneumatic disc brake, achieving a lightweight, integral clamp body structure. It also accommodates the vertical installation of the drive mechanism, offering ample space and freedom from assembly constraints. The innovative external machining method allows for the formation of a high-precision arc-shaped surface within the clamp body to mate with the semi-circular bearing, significantly reducing machining costs and increasing efficiency compared to structures using angled heads. Furthermore, the assembly utilizes the semi-circular bearing for positioning, increasing the contact area and reducing contact force, while also distributing stress on the top surface of the second assembly cavity, resulting in better overall structural strength. This positioning prevents the pressure arm from shifting, improving braking efficiency. The clamp body is easy to clamp and position, allowing all machining items except the drive mechanism mounting surface to be completed in a single setup on a machining center, ensuring precise positioning between the various machined parts of the clamp body. This clamp body structure also facilitates the assembly of pneumatic disc brake components. After the semi-circular bearing is installed, the pressure arm assembly is simple to assemble and automatically returns to its original position. The adjustment mechanism assembly can also be assembled simply by placing it in, greatly simplifying the assembly of this part of the structure.
[0052] Furthermore, the pneumatic disc brake in this design features simple assembly of its components, with ample space for assembly, resulting in higher efficiency. Simultaneously, the assembly precision between all components is reliable, the adjustment mechanism is stable with sufficient stroke, the caliper slides smoothly, the brake pads move up and down smoothly, and the return is rapid and reliable. Additionally, the caliper's contact surface is an arc, not perpendicular to a large flat surface, thus preventing excessive load on the top surface of the second assembly cavity of the caliper, extending its service life and reducing the failure rate.

[0055] Example 3
