Description

Technical Field

[0001] This application relates to the field of transmission systems, and more specifically, to a brake holder for a brake and the brake itself. Background Technology

[0002] Brakes are widely used in transmission systems, such as those in vehicles. Existing brakes generally consist of a motor mount and a support mount, which together hold the drive shaft. Between the motor mount and the support mount are various brake components, including a piston, a spring for biasing the piston and a spring sleeve housing the spring, a friction pad assembly that engages with the drive shaft and can contact and disengage from the piston, and a sensor for sensing the distance between the piston and the friction pad assembly. With use, internal brake components, such as the friction pad assembly, deteriorate over time due to wear. Therefore, operators need to frequently disassemble the brake, i.e., remove the motor mount from the support mount, to inspect and replace the internal components.

[0003] However, because the aforementioned components inside the existing brake are independent of each other, each disassembly causes these individual components to separate. After inspection and replacement, the separated components need to be reassembled to maintain their proper relative positioning. Therefore, the disassembly and assembly of this brake is time-consuming and labor-intensive. In particular, the disassembly and assembly of certain components inside the brake may require the use of special tools, further complicating the process. Additionally, the sensor's position relative to the piston may change each time the brake is disassembled. To ensure the sensor's sensing accuracy after reassembly, calibration and adjustment of the sensor are necessary during brake reassembly.

[0004] Therefore, there is a need for an improved brake that overcomes the aforementioned problems of existing brakes. Utility Model Content

The first end of the body forms a radially outwardly extending protrusion including a first surface configured to contact the motor seat and a second surface opposite to the first surface to contact the support seat. The second end of the body forms a radially inwardly extending extension adjacent to the drive shaft. The protrusion includes a plurality of grooves formed on the first surface and a plurality of through holes penetrating the first and second surfaces.

[0006] The body includes a radially outer surface and a radially inner surface, and may further include a first stepped portion extending radially inward from the radially inner surface adjacent to a first end, a second stepped portion extending radially inward from the radially inner surface away from the first end and adjacent to the first stepped portion, and a third stepped portion extending radially inward from the radially inner surface between the second stepped portion and the extended portion.

[0012] In the second channel, a blocking element that prevents hydraulic oil from passing through may be provided between the first surface of the protrusion and the first channel.

[0013] The brake seat may further include a lubricating oil passage extending through the radial inner and radial outer surfaces of the body at the third step.

[0014] The brake housing may further include a lubricating oil cavity defined at its radially inner surface that communicates with a lubricating oil passage but does not communicate with the motor housing or the support housing.

[0030] Figure 1A This illustration shows a perspective view of a brake holder for a brake according to an embodiment of the present application. Figure 1B and Figure 1C Cross-sectional and side views of the brake seat according to Figure 1 are shown respectively.

[0031] Figures 1A to 1C The brake seat shown according to this utility model is intended to be mounted to, as... Figure 2 and Figure 3 The brake shown according to this invention allows for flexible disassembly of the brake depending on application requirements.

[0032] See Figures 1A to 1C and combined Figure 2 and Figure 3According to the present invention, the brake seat 10 includes a hollow body 100, which includes a first end 101 configured adjacent to a motor seat 20 of the brake 1 and a second end 102 configured adjacent to a support seat 30 of the brake 1. The body 100 is configured to surround a drive shaft 2 intended to be braked by the brake 1.

[0033] The first end 101 of the body 100 has a radially outwardly extending protrusion 110, which includes a first surface 111 configured to contact the motor seat 20 and a second surface 112 opposite to the first surface 111 to contact the support seat 30. The second end 102 of the body 100 has a radially inwardly extending extension 120 adjacent to the drive shaft 2.

[0034] The protrusion 110 of the body 100 includes a plurality of grooves 113 formed on the first surface 111 and a plurality of through holes 114 penetrating the first surface 111 and the second surface 112.

[0035] The body 100 can be formed into a generally hollow cylindrical structure, such as a cylindrical structure.

[0036] Each of the plurality of grooves 113 may be a threaded groove extending from a first surface 111 of the protrusion 110 of the body 100 toward a second surface 112, for example, extending perpendicular to the first surface 111 and the second surface 112 but not extending to the second surface 112. A plurality of corresponding first through holes are formed on the motor housing 20, each aligned with one of the plurality of grooves 113. Thus, by means of a plurality of fasteners, such as bolts, passing through the plurality of first through holes of the motor housing 20 and the plurality of grooves 113 of the protrusion 110 of the body 100, the motor housing 20 and the brake housing 10 can be attached to each other.

[0037] Each of the plurality of through holes 114 may be a threaded through hole extending from a first surface 111 of the protrusion 110 of the body 100 toward a second surface 112, for example, extending perpendicular to the first surface 111 and the second surface 112 and penetrating through the first surface 111 and the second surface 112. A plurality of corresponding second through holes are formed on the motor seat 20, each aligned with one of the plurality of through holes 114, and a plurality of corresponding grooves, for example, threaded grooves, are formed on the support seat 30, each aligned with one of the plurality of through holes 114. Thus, by means of a plurality of fasteners, such as bolts, which sequentially pass through the plurality of first through holes of the motor seat 20, the plurality of grooves 113 of the protrusion 110 of the body 100, and the plurality of grooves of the support seat 30, the motor seat 20, the brake seat 10, and the support seat 30 can be attached to each other; that is, the brake seat 10 is fixed between the motor seat 20 and the support seat 30.

[0038] By providing the aforementioned brake seat 10, when the brake seat 10 is installed in the brake 1, specifically between the motor seat 20 and the support seat 30 of the brake 1, and the drive shaft 2 is surrounded by the brake seat 10 and rotatably held by the motor seat 20 and the support seat 30, and specifically supported by two bearings 3 and 4 surrounding the drive shaft at both ends of the drive shaft 2, the components of the brake 1 located between the motor seat 20 and the support seat 30 (piston, friction plate assembly, bias spring and spring sleeve, sensor for sensing the position of the piston, etc.) are kept contained between the body 100 of the brake seat 10 and the drive shaft 2.

[0039] By forming a plurality of grooves 113 at the first surface 111 and a plurality of through holes 114 through the first surface 111 and the second surface 112 at the protrusion 110 of the body 100, the brake 1 can be flexibly disassembled according to application requirements. Specifically, when the plurality of fasteners, such as bolts, used to attach the motor seat 20, the brake seat 10 and the support seat 30 to each other are removed and the plurality of fasteners, such as bolts, used to attach the motor seat 20 and the brake seat 10 to each other remain engaged, the motor seat 20, the brake seat 10 and the components of the brake 1 housed between the body 100 of the brake seat 10 and the drive shaft 2 are disassembled as a whole from the support seat 30. This disassembly method is suitable for situations where it is not necessary to access the components of the brake 1 housed between the body 100 of the brake seat 10 and the drive shaft 2, such as when only the support seat 30 needs to be inspected and maintained. This disassembly method is simple and time-saving. The components of the brake 1 housed between the body 100 of the brake seat 10 and the drive shaft 2 remain fixed, that is, the relative positions of the components remain unchanged. Therefore, it is not necessary to use special disassembly tools to complete the disassembly. After the disassembly is completed and before the brake 1 is reinstalled, it is not necessary to recalibrate and adjust the sensor. Furthermore, it is not necessary to use special installation tools to reinstall the brake 1.

[0040] On the other hand, when the fasteners, such as bolts, used to attach the motor housing 20, brake housing 10, and support housing 30 to each other are removed, and when the fasteners, such as bolts, used to attach the motor housing 20 and brake housing 10 to each other are also removed, the motor housing 20, brake housing 10, and support housing 30 disengage from each other, and the components of the brake 1 housed between the body 100 of the brake housing 10 and the drive shaft 2 can also be removed in sequence. That is, all components of the brake 1 can be disengaged from each other. In this disassembly case, all components of the brake 1 can be accessed, such as the piston, friction plate assembly, bias spring and spring sleeve, sensor for sensing the position of the piston, etc. After disassembly is completed in this manner and before reassembling the brake 1, it may be necessary to reinstall the brake 1 with the aid of specialized installation tools (e.g., tools for installing spring sleeves), and since the relative position of the sensor and the piston may change, the sensor also needs to be calibrated or adjusted to ensure the sensing accuracy of the sensor after reassembly of the brake 1.

[0041] like Figure 1A As shown, the body 100 of the brake seat 10 includes a radially inner surface 103 and a radially outer surface 104. The body 100 further includes a first step portion 130 extending radially inward from the radially inner surface 103 adjacent to the first end 101, a second step portion 140 extending radially inward from the radially inner surface 103 away from the first end 101 and adjacent to the first step portion 130, and a third step portion 150 extending radially inward from the radially inner surface 103 between the second step portion 140 and the extension portion 120.

[0042] The structure of the brake seat 10 according to this utility model is designed accordingly based on the motor seat 20, the support seat 30, and the components located between the motor seat 20 and the support seat 30. In particular, the first stepped portion 130, the second stepped portion 140, and the third stepped portion 150 of the body 100 of the brake seat 10 are designed accordingly based on the components of the brake 1 located between the motor seat 20 and the support seat 30. The components of the brake 1 and how these components are arranged relative to the brake seat 10 will be described below.

[0043] The motor mount 20 is configured to hold a motor (not shown) for driving the drive shaft 2.

[0044] The support 30 is configured to rotatably hold the drive shaft 2 together with the motor housing 20. In brakes without the brake housing 10 according to the present invention, the support 30 and the motor housing 20 are attached to each other and hold multiple components of the brake 1 (piston, friction pad assembly, bias spring and spring sleeve, sensor for sensing the position of the piston, etc.) between them. In the brake 1 provided with the brake housing 10 according to the present invention, the motor housing 20 is attached to the first surface 111 of the protrusion 110 of the body 100 of the brake housing 10, and the support 30 is attached to the second surface 111 of the protrusion 110 of the body 100 of the brake housing 10, such that the brake housing 10 is attached between the motor housing 20 and the support 30, and the aforementioned components of the brake 1 are accommodated between the body 100 of the brake housing 10 and the drive shaft 2.

[0045] The bias spring 40 is surrounded by a hollow spring sleeve 41, which is located between the protrusion 110 of the brake seat 10 body 100 and the drive shaft 2 and abuts against the motor seat 20. The spring sleeve 41 is axially held between the motor seat 20 and the piston 50, which will be described below, so that the bias spring 40 can move back and forth in the axial direction (i.e., in...). Figure 2 and Figure 3 (Moves left and right). The bias spring 40 is configured to apply a biasing force to the piston 50 toward the friction plate assembly 60.

[0046] The piston 50 is located between the radially inner surface 103 of the body 100 of the brake seat 10 and the drive shaft 2, and contacts the bias spring 40 at one end and is configured to reciprocate in the axial direction. Specifically, the piston 50 is arranged axially between the spring sleeve 41 and the friction plate assembly 60, and radially between the radially inner surface 103 of the body 100 of the brake seat 10 and the drive shaft 2. The piston 50 includes a piston body 51 adjacent to a second stepped portion 140 of the body 100, a radially outwardly extending radial protrusion 52 from the piston body 51 to adjacent the spring sleeve 41 and the first stepped portion 130 of the body 100, and an axially outwardly extending axially from the piston body 51 to adjacent the friction plate assembly 60. Overall, the piston 50 is formed as an annulus around the drive shaft 2 and is configured to reciprocate in the axial direction to engage or disengage from the friction plate assembly 60.

[0047] like Figure 2 As shown, the brake seat 10 includes a hydraulic oil passage 160 at the protrusion 11 that penetrates the radial inner surface 103 and the radial outer surface 104 of the body 100. Hydraulic oil can be supplied from the radial outer surface 104 of the body 100 to the radial inner surface 103 of the body 100 through this hydraulic oil passage.

[0048] Specifically, the hydraulic oil passage 160 includes a first passage 161, a second passage 162, and a third passage 163 that are interconnected. The first passage 161 extends from the radially outer surface 104 into the protrusion 110 of the body 100. The second passage extends from the first surface 111 of the protrusion 110 into the protrusion 110 and communicates with the first passage 161. A blocking element 164 is provided in the second passage 162 between the first surface 111 of the protrusion 110 and the first passage 161 to prevent the passage of hydraulic oil. The third passage 163 connects to the second passage 162 from the first stepped portion 130. In other words, the first passage 161 forms the inlet of hydraulic oil, the third passage 163 forms the outlet of hydraulic oil, and the second passage 162 forms the passage connecting the inlet and outlet. It should be noted that the first passage 161, the second passage 162, and the third passage 163 are designed for ease of machining and to accommodate the axial misalignment of the hydraulic oil inlet and outlet.

[0049] Hydraulic oil can enter from the first channel 161 at the radial outer surface 104 of the body 100 and flow into the hydraulic oil chamber 170 formed between the radial protrusion 52 and the second step 140 of the piston 50 through the third channel 163. When hydraulic oil is filled into the hydraulic oil chamber 170, the radial protrusion 52 of the piston 50 is pushed towards the bias spring 40 by the hydraulic oil, so that the entire piston 50 moves axially away from the friction plate assembly 60 under the action of the thrust applied by the hydraulic oil, causing the piston 50 to disengage from the friction plate assembly 60, and the bias spring 40 is compressed into the spring sleeve 41. When there is no hydraulic oil in the hydraulic oil chamber 170, the radial protrusion 52 of the piston 50 is subjected to the spring force of the bias spring 40 towards the friction plate assembly 60, so that the entire piston 50 moves axially towards the friction plate assembly 60 under the action of the spring force, causing the piston 50 to engage with the friction plate assembly 60.

[0050] It should be noted that, in order to enable the piston to move axially, the body 100 of the brake seat 10 is configured such that a cavity 180 is formed between the piston body 51 of the piston 50 and the third step portion 150. The arrangement of the hydraulic oil chamber 170 and the cavity 180 provides space that allows the piston 50 to move axially.

[0051] To retain hydraulic oil in the hydraulic oil chamber 170 and prevent leakage into the spring sleeve 41 and the cavity 180, a first piston groove may be provided on the surface of the radial protrusion 52 of the piston 50 facing the first step 130. A first piston seal 54 is provided in this groove to prevent hydraulic oil from leaking from the hydraulic oil chamber 170 into the spring sleeve 41. Additionally, a second piston groove may be provided on the surface of the piston body 51 facing the second step 140. A second piston seal 55 is provided in this groove to prevent hydraulic oil from leaking from the hydraulic oil chamber 170 into the cavity 180. The first piston seal 54 and the second piston seal 55 are, for example, O-rings.

[0052] Friction pad assembly 60 is located between the radially inner surface 103 of the brake seat 10 body 100 and the drive shaft 2, and between the piston 50 and the extension 120, and is configured to engage with the drive shaft 2. Friction pad assembly 60 includes an inner friction pad 61 and an outer friction pad 62. Specifically, the outer circumferential portion of friction pad assembly 60 is adjacent to the radially inner surface 103 of the brake seat 10 body 100, and the inner circumferential portion of friction pad assembly 60 engages with the drive shaft 2. Friction pad assembly 60 includes a first axial end abutting against the extension 120 of the brake seat 10 body 100 and a second axial end opposite to the first circumferential end. The specific structures of the inner friction pad 61 and the outer friction pad 62 are known in the art and will not be described in detail herein.

[0053] When the piston 50 moves axially under the force of the spring to engage with the friction plate assembly 60, the friction plate assembly 60 is stationary, and thus the drive shaft 2, which meshes with the friction plate assembly 60, is also stationary, achieving braking of the drive shaft 2. When the piston 50 moves axially under the thrust of the hydraulic oil to disengage from the friction plate assembly 60, the friction plate assembly 60 can rotate with the drive shaft 2, thus achieving normal operation of the drive shaft 2.

[0054] The brake 1 may also include a sensor 70 for sensing the position of the piston 50 relative to the friction plate assembly 60, specifically sensing the distance between them. The sensor 70 may be a common distance sensor, which is disposed between the motor housing 20 and the piston 50 and may be attached to the motor housing 20. The sensor 70 can detect whether the piston 50 and the friction plate assembly 60 are in an engaged or disengaged state.

[0055] The above describes in detail the structure of the brake seat 10 in conjunction with the various components of the brake 1. As can be seen from the above description, the structure of the brake seat 10 is generally designed based on the structure of the various components of the brake 1, and can be adjusted accordingly depending on changes in the structure of the various components of the brake 1, and is not limited to... Figures 1A to 1C The structure shown.

[0056] like Figure 1A , Figure 2 and Figure 3 As shown, the brake seat 10 may include a lubricating oil passage 151 extending through the radially inner surface 103 and radially outer surface 104 of the body 100 at a third step portion 150. A lubricating oil cavity 152 is formed radially between the third step portion 150 and the drive shaft 2, and axially between the piston 50 and the extension 120 of the body 100. By supplying lubricating oil to the lubricating oil cavity 152 through the lubricating oil passage 151, the lubricating oil can lubricate the friction plate assembly 60 and the drive shaft 2.

[0057] To retain the lubricating oil within the lubricating oil cavity 152 and prevent communication with the outside, i.e., to prevent the lubricating oil from flowing into the motor housing 20 or the support housing 30, it is preferable that the brake housing 10 is configured to have a closed lubricating oil cavity 152 surrounding the friction plate assembly 60 and the drive shaft 2. The closed lubricating oil cavity 152 includes communication with the lubricating oil passage 151 defined at its radially inner surface 103, but not communication with the motor housing 20 or the support housing 30. For this purpose, as... Figure 3 As shown, a first drive shaft seal 5 is provided between a first bearing 3 supporting the drive shaft 2 and the motor housing 20 at one end of the drive shaft 2 adjacent to the motor housing 20, and a second drive shaft seal 6 is provided between a second bearing 4 supporting the drive shaft 2 and the support housing 30 at the other end of the drive shaft 2 adjacent to the support housing 30, and between the extension 120 of the brake housing 10 body 100 and the drive shaft 2. The first drive shaft seal 5 and the second drive shaft seal 6 are, for example, lip seals.

[0058] The first drive shaft seal 5 prevents lubricating oil from communicating between the motor housing 20 and the lubricating oil chamber 152, while the second drive shaft seal 6 prevents lubricating oil from communicating between the support 30 and the lubricating oil chamber 152. Furthermore, the aforementioned second piston seal 55 prevents the hydraulic oil in the hydraulic oil chamber 170 from communicating with the lubricating oil in the lubricating oil chamber 152. Therefore, by providing the first drive shaft seal 5, the second drive shaft seal 6, and the second piston seal 55, a closed lubricating oil chamber 152 is formed radially between the third step portion 150 and the drive shaft 2, and axially between the piston 50 and the extension 120 of the body 100.

[0059] The enclosed lubrication chamber 152 is particularly advantageous for high-speed operation of the drive shaft 2. When the drive shaft 2 rotates at high speed, the friction plate assembly 60 also rotates at high speed, and a large amount of heat may be generated between them. By supplying lubricating oil to the enclosed lubrication chamber 152 through the lubrication channel 151, the desired heat dissipation for the drive shaft 2 and the friction plate assembly 60 can be achieved. In existing brakes that do not have the brake seat 10 according to this invention, the aforementioned enclosed lubrication chamber is not formed, and the lubricating oil for lubricating the drive shaft 2 and the friction plate assembly 60 is in communication with the lubricating oil for the support seat 30. Therefore, it is difficult to supply lubricating oil specifically for the high-speed operation of the drive shaft 2 and the friction plate assembly 60, and thus it is difficult to achieve the heat dissipation effect on the drive shaft 2 and the friction plate assembly 60 that can be achieved by the solution of this invention with the aforementioned enclosed lubrication chamber 152.

[0060] This utility model also proposes a brake. See [link to relevant documentation]. Figure 2 and Figure 3 The brake 1 includes:

[0061] Brake seat 10 according to the present utility model;

[0062] Motor housing 20 for holding the motor driving the transmission shaft 2;

[0063] A support 30 for supporting the drive shaft 2 together with the motor housing 20, wherein the brake housing 10 is located between the motor housing 20 and the support 30; and

[0064] Multiple components located axially between the motor seat 20 and the support seat 30 and radially between the brake seat 10 and the drive shaft 2.

[0065] The aforementioned components are conventional components in a brake, including:

[0066] The protrusion 110 of the body 100 of the brake seat 10 is located between the drive shaft 2 and the hollow spring sleeve 41 of the motor seat 20, and the bias spring 40 is surrounded by the spring sleeve 41.

[0067] A piston 50 is located between the radial inner surface 103 of the body 100 of the brake seat 10 and the drive shaft 2, and contacts the bias spring 40 at one end and is configured to reciprocate in the axial direction.

[0068] A friction pad assembly 60 is located between the radial inner surface 103 of the brake seat 10 body 100 and the drive shaft 2, and between the piston 50 and the extension 120 of the brake seat 10 body 100, and is configured to mesh with the drive shaft 2; and

[0069] A sensor 70 is located between the motor housing 20 and the piston 50 and is configured to sense the distance between the piston 50 and the friction plate assembly 60. The sensor 70 can be a common distance sensor. The sensor 70 can detect whether the piston 50 and the friction plate assembly 60 are in an engaged or disengaged state.

[0070] The details of the brake seat 10 and other components of the brake 1 described above also apply to the brake 1 according to this utility model, so the details already described will not be repeated here.

[0071] In summary, by providing a brake holder and brake according to this invention, the brake can be flexibly disassembled depending on application requirements. On one hand, the brake holder and the various components of the brake housed between the brake holder body and the drive shaft can be disassembled as a whole from the support base, thus eliminating the need for specialized disassembly tools. Furthermore, after disassembly and before reinstalling the brake, there is no need to recalibrate and adjust the sensors, and reinstallation of the brake is also unnecessary without specialized installation tools. On the other hand, all components of the brake can be disassembled and decoupled from each other, thereby allowing access to all parts of the brake for inspection and maintenance.
