Description

Technical Field

[0001] This utility model relates to the field of brake cable wear compensation technology, and in particular to a wear compensation mechanism for brake cables. Background Technology

[0002] Brake cables are a critical component of a vehicle's braking system, used to transmit braking force. The main function of a brake cable wear compensation mechanism is to automatically or manually compensate for wear after the brake cables become worn, ensuring the effectiveness and reliability of the braking system. Currently, the brake cables used in automotive braking systems are made of metal wire, which gradually wears down during frequent use, leading to a reduction in braking force and affecting driving safety. Although there are some methods on the market for maintaining brake cables through regular inspections, these not only increase maintenance costs but also fail to fundamentally solve the problem.

[0003] A search revealed Chinese Patent Publication No. CN212899459U, which discloses a friction braking wear compensation mechanism. The mechanism includes a base frame, a linkage shaft, a brake disc, an electromagnetic chuck, an electromagnet, a mounting base, and an elastic element. The linkage shaft is mounted on the base frame and is movably fitted with it. The brake disc is mounted at the end of the linkage shaft. The electromagnetic chuck is mounted on the base frame. The electromagnet is installed between the electromagnetic chuck and the mounting base, with a clearance fit between them. The mounting base is linked to the linkage shaft. The elastic element is mounted on the mounting base and is in a pre-tightened state, with the pre-tightening direction facing the brake disc. The electromagnet is linked with the pre-tightened elastic element. This invention ensures the required positive pressure for friction braking when the clearance between the brake disc and the rotating component changes. The positive pressure is not directly applied by electromagnetic force, but rather through the pre-tightening force of the elastic element. However, in actual use, while the device compensates for wear through the pre-tightening force of the elastic element, the compensation structure is susceptible to interference from external dust and humidity, leading to aging and damage within the structure, thus reducing its service life and effectiveness. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wear compensation mechanism for brake cables, aiming to improve the problem in the prior art that the compensation structure is affected by external dust and humidity, leading to aging and damage inside the compensation structure, and thus reducing the service life of the compensation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wear compensation mechanism for brake cables, comprising a housing, an elastic compensation piston slidably mounted inside the housing, a filter disc fixedly connected to the right side of the housing, a connecting plate fixedly connected to the bottom wall of the housing, a filter shell fixedly connected to the bottom wall of the connecting plate, filter plates fixedly connected to the front and rear sides of the bottom wall of the filter shell, a miniature fan fixedly connected to the inner top wall of the filter shell, a conveying shell connected to the left side of the miniature fan, a limiting plate fixedly connected to the top of the conveying shell, the outer wall of the limiting plate fixedly connected to the left side of the inner wall of the housing, an exhaust valve connected to the top wall of the housing, and an installation mechanism provided in the middle of the top wall of the housing.

[0006] The above technical solution reduces the impact of dust particles entering the housing and affecting the use of the compensation structure by connecting the filter disc. At the same time, the airflow is transported by the micro fan, so that the transported airflow first passes through the filter plate to complete filtration and drying, and then enters the housing 1 to complete the transport, thereby achieving the effect of air replacement for the compensation structure inside the housing and reducing the moisture content.

[0007] As a further description of the above technical solution:

[0008] The mounting mechanism includes a connecting column, the bottom wall of which is fixedly connected to the middle of the top wall of the outer casing. Rotating shells are rotatably connected to the front and rear sides of the connecting column. Locking plates are rotatably connected to the left and right sides of the rear rotating shell. A bolt is threaded to one side of each locking plate. Locking grooves are provided on the left and right sides of the front rotating shell. The adjacent sides of the two locking plates are respectively engaged with the corresponding locking grooves. One end of the bolt is threaded to the locking groove. A mounting column is fixedly connected to the top center of the connecting column.

[0009] The above technical solution enables the two rotating shells to rotate in opposite directions under the engagement of the mounting column, thereby achieving the purpose of initial clamping and installation at the fixed position. Subsequently, the bolts are locked to the front rotating shell under the engagement of the locking plate and the locking groove, which improves the flexibility of the device installation.

[0010] As a further description of the above technical solution:

[0011] The mounting mechanism also includes two rubber rings, the inner walls of which are respectively fixedly connected to the middle of the corresponding bolts.

[0012] The above technical solution reduces the rotational damage to the locking plate caused by the bolts, thanks to the connection of the rubber ring.

[0013] As a further description of the above technical solution:

[0014] The left and right rear ends of the front rotating shell are fixedly connected with locking posts, and the left and right front ends of the rear rotating shell are provided with locking grooves. The rear ends of the two locking posts are respectively engaged with the corresponding locking grooves.

[0015] The above technical solution improves the strength of the rotating shell connection by engaging the locking post and the locking groove.

[0016] As a further description of the above technical solution:

[0017] A sealing ring is fixedly installed on the outer wall of the conveying shell, and the outer wall of the sealing ring is fixedly connected to the left side of the filter shell.

[0018] The above technical solution improves the sealing performance of the conveyor shell when conveying airflow.

[0019] As a further description of the above technical solution:

[0020] An installation sleeve is fixedly installed on the left end of the elastic compensation piston, and the outer wall of the installation sleeve has an inclined surface.

[0021] The above technical solution facilitates the connection and installation of the elastic compensation piston by means of the mounting sleeve, thereby improving the pressure resistance of the mounting sleeve by the opening of the inclined surface.

[0022] As a further description of the above technical solution:

[0023] Rubber pads are fixedly connected to adjacent sides of the inner walls of the two rotating shells, and the outer walls of the two rubber pads are designed to be smooth.

[0024] The above technical solution improves the clamping and fixing effect of the rotating shell on the fixed position by connecting the rubber pad.

[0025] As a further description of the above technical solution:

[0026] Positioning blocks are fixedly connected to the left and right sides of the inner walls of the two rotating shells, and the multiple positioning blocks are all designed symmetrically.

[0027] The above technical solution improves installation efficiency by connecting the positioning blocks.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by installing and fixing the filter plate, the situation where dust particles enter the shell and affect the use of the compensation structure is reduced. At the same time, with the start of the micro fan, the outside air is drawn in and then enters the shell through filtration and drying by the filter plate, thereby achieving the effect of replacing the air inside the shell, reducing the moisture content, and thus avoiding the situation of accelerating the aging and damage inside the compensation structure.

[0030] 2. In this utility model, by engaging the mounting post with the corresponding desired installation position, the two rotating shells are flipped, causing them to rotate towards each other, thereby achieving the purpose of initial clamping of the fixed position. Then, under the rotation of the locking plate, the locking plate engages with the locking groove, and the bolt is threaded into the locking groove, thus fixing the two rotating shells and improving the flexibility of the device's installation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a wear compensation mechanism for brake cables, comprising a housing 1, an elastic compensation piston 3 slidably mounted inside the housing 1, a filter disc 4 fixedly connected to the right side of the housing 1, which improves the blocking of dust particles under the connection of the filter disc 4, a connecting plate 5 fixedly connected to the bottom wall of the housing 1, a filter shell 6 fixedly connected to the bottom wall of the connecting plate 5, and filter plates 7 fixedly connected to the front and rear sides of the bottom wall of the filter shell 6, through which air is filtered and dried, a miniature fan 8 fixedly connected to the inner top wall of the filter shell 6, and a conveying shell 9 connected to the left side of the miniature fan 8, thereby drawing in outside air when the miniature fan 8 is activated, and conveying it through the conveying shell 9 to replace the air inside the housing 1, a limiting plate 10 fixedly connected to the top of the conveying shell 9, the outer wall of the limiting plate 10 fixedly connected to the left side of the inner wall of the housing 1, an exhaust valve 11 connected to the top wall of the housing 1, through which the replaced air is discharged, and an installation mechanism 2 is provided in the middle of the top wall of the housing 1;

[0040] Specifically, the installation and connection of filter plate 4 reduces the possibility of dust particles entering the interior of housing 1, thereby effectively preventing these particles from negatively impacting the normal use of the compensation structure. When the micro fan 8 starts, it draws in outside air and filters it through filter plate 7. The function of filter plate 7 is not only to filter out impurities in the air, but also to remove moisture from the air, making it dry. The air that has undergone dual treatment is then transported to the interior of housing 1 through conveyor shell 9. After the airflow enters the interior of housing 1, it can effectively replace the original air, reduce the moisture content inside housing 1, and thus reduce the potential damage of moisture to the internal components of the compensation structure, thereby avoiding the risk of accelerated aging and damage, and ensuring the long-term stable operation of the equipment.

[0041] Reference Figure 1 , Figure 2 and Figure 5The installation mechanism 2 includes a connecting column 201, the bottom wall of which is fixedly connected to the middle of the top wall of the outer casing 1. Rotating shells 202 are rotatably connected to both the front and rear sides of the connecting column 201, allowing the installation mechanism 2 to initially clamp and fix the fixed position as the rotating shells 202 rotate. Locking plates 203 are rotatably connected to both the left and right sides of the rear rotating shell 202, with bolts 204 threaded onto one side of each locking plate 203. Locking grooves 211 are provided on both the left and right sides of the front rotating shell 202. Each locking plate 203 has its adjacent side engaged with its corresponding locking groove 211. As the locking plate 203 rotates, one end of it locks with the locking groove 211, thereby limiting the position of the rotating shell 202. One end of the bolt 204 is threadedly connected to the locking groove 211. A mounting post 206 is fixedly connected to the top center of the connecting post 201. The mounting mechanism 2 also includes two rubber rings 205, the inner walls of which are fixedly connected to the center of the corresponding bolts 204.

[0042] Specifically, during the initial installation of the device, the mounting post 206 is first engaged with the corresponding installation position, thereby flipping the two rotating shells 202 to open them outwards and aligning them with the interior of the rotating shells 202. Then, they are rotated inwards to clamp them, ensuring that the rotating shells 202 are aligned and clamped as intended. Next, the locking plate 203 is rotated to engage with the locking groove 211, thereby ensuring that the locking plate 203 is fixed in the corresponding position. By rotating the bolt 204, it is locked with the front rotating shell 202, thereby ensuring that the two rotating shells 202 are fixed on the device. This improves the flexible installation effect of the device and also ensures the stability and reliability of the entire device during use. The connection of the rubber ring 205 reduces the rotational damage of the bolt 204 to the locking plate 203.

[0043] Reference Figure 1 , Figure 4 and Figure 5 The left and right rear ends of the front rotating shell 202 are fixedly connected with locking posts 209, and the left and right front ends of the rear rotating shell 202 are provided with locking grooves 210. The rear ends of the two locking posts 209 are respectively engaged with the corresponding locking grooves 210. The inner walls of the two rotating shells 202 are fixedly connected with rubber pads 208 on adjacent sides, and the outer walls of the two rubber pads 208 are both designed to be smooth.

[0044] Specifically, the rear ends of the two engaging posts 209 engage with the corresponding engaging slots 210, thereby increasing the connection strength of the two rotating shells 202, and the rubber pads 208 improve the fixing effect of the rotating shells 202.

[0045] Reference Figure 1 , Figure 3 and Figure 5A sealing ring 12 is fixedly installed on the outer wall of the conveying shell 9, and the outer wall of the sealing ring 12 is fixedly connected to the left side of the filter shell 6; an installation sleeve 13 is fixedly installed on the elastic compensation piston 3, and the outer wall of the installation sleeve 13 is provided with an inclined surface; positioning blocks 207 are fixedly connected to the left and right sides of the inner walls of the two rotating shells 202, and the multiple positioning blocks 207 are all symmetrically designed.

[0046] Specifically, the sealing ring 12 improves the sealing effect between the conveying shell 9 and the filter shell 6, the inclined surface on the outer wall of the mounting sleeve 13 improves the compressive strength of the outer wall of the mounting sleeve 13, and the positioning block 207 improves the installation efficiency of the mechanism.

[0047] Working Principle: Upon initial use, the installation and connection of filter disc 4 reduces the likelihood of dust particles entering the interior of housing 1 and affecting the use of the compensation structure. Then, by activating the micro fan 8, outside air is drawn in through filter plate 7. This air, filtered and dried by filter plate 7, is then transported through conveyor shell 9. The filtered and dried airflow enters the interior of housing 1, replacing the air inside and reducing moisture content. This prevents accelerated aging and damage to the compensation structure. During initial installation, the mounting post 206 engages with the corresponding position, causing the two rotating shells 202 to flip outwards. After alignment, they are rotated inwards to achieve a fixed position. Then, the locking plate 203 rotates, engaging with the locking groove 211. Finally, the bolt 204 is rotated to lock the front rotating shell 202, thus fixing the two rotating shells 202 and improving the flexibility of installation.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
