Description

Technical Field

[0001] The present invention relates to the technical field of friction plates, and specifically to a protection device for a brake friction plate. Background Art

[0002] A friction brake is a mechanical part that stops or decelerates a moving part in a machine. Commonly known as a brake, it uses the frictional resistance generated when two moving surfaces come into contact with each other to convert the kinetic energy and potential energy during the movement of an automobile into heat energy, thereby achieving a device for decelerating or stopping the automobile. The performance of the friction material (brake part) used on the brake directly affects the braking process, and the main factors affecting its performance are the working temperature and the temperature rise rate. The friction material should have a high and stable friction coefficient and good wear resistance.

[0003] The brake friction plates of the prior art will be worn during use, which will affect the normal use effect of the friction plates after wear and lead to accidents. Therefore, we propose a protection device for brake friction plates. Summary of the Invention

[0008] Preferably, a first slot and two second slots are opened inside the protection plate, both of the second slots are communicated with the first slot, and a protection mechanism is arranged inside the first slot.

[0009] Preferably, the protection mechanism includes two first protective pads. One ends of the two first protective pads close to each other are fixedly connected with clamping sleeves. A spring is arranged at one ends of the two clamping sleeves close to each other. Limiting blocks are fixedly connected to the outer surfaces of the two clamping sleeves.

[0013] Compared with the prior art, the present invention provides a protection device for a brake friction plate, which has the following beneficial effects: 1. After the protection piece wears and becomes thinner, the arc-shaped sleeve is driven to impact, so that the clamping sleeve slides along the support plate and disengages from the second protective pad. Thus, the second protective pad can move upward through the slot by the elastic force of the elastic rope, and can assist the protection piece to work, avoiding the possible influence caused by the wear of the protection piece.

[0014] 2. After the protection piece is worn and becomes thinner by friction, the first protective pad can be exposed, so as to work together with the protection piece to ensure the working effect of the protection piece and protect the protection piece, avoiding the influence on the normal use due to the weakening of the performance of the protection piece.

At the same time, by arranging the limiting block, and the limiting block is inside the second slot, it can avoid the excessive protrusion of the limiting block and affecting the normal use.

[0016] 4. After the second protective pad is rubbed and slides, the vertical rod is pulled, and the vertical rod drives the connecting frame to open and squeeze the first protective pad, which can avoid the shrinkage of the spring due to the friction and extrusion of the first protective pad, and can effectively support the first protective pad.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] Please refer to Figures 1-8 , the present invention provides a technical solution: a brake friction plate protection device, including a connecting disc 1 and a protective sheet 2. The outer surface of the protective sheet 2 is fixedly connected to the inner wall of the connecting disc 1. An auxiliary mechanism 3 is provided on the top of the connecting disc 1. A first slot 22 and two second slots 23 are opened inside the protective sheet 2. Both of the two second slots 23 communicate with the first slot 22. A protection mechanism 21 is provided inside the first slot 22. The number of the protection mechanism 21 and the auxiliary mechanism 3 is two groups each. The two groups of the protection mechanism 21 and the auxiliary mechanism 3 are both annularly arranged centered on the central axis of the connecting disc 1.

[0022] The auxiliary mechanism 3 includes a fixing frame 31. The fixing frame 31 is fixedly connected to the top of the connecting disk 1. A second protective pad 32 is arranged inside the fixing frame 31. A support plate 33 is fixedly connected to the inner wall of the fixing frame 31. A bushing 34 is sleeved on the outer surface of the support plate 33. The bushing 34 is slidably connected to the support plate 33. An arc-shaped plate 35 is fixedly connected to the top of the bushing 34. Slots 311 are formed at both ends of the inner wall of the fixing frame 31. Both ends of the second protective pad 32 are connected to the slots 311 through connecting rods.

[0023] A connecting frame 36 is fixedly connected to the inner wall of the fixing frame 31. A clamping rod 38 is fixedly connected to the inner wall of the connecting frame 36. The clamping rod 38 penetrates through the support plate 33. An elastic cord 37 is fixedly connected inside the fixing frame 31. The elastic cord 37 contacts the bottom of the second protective pad 32. After the protective sheet 2 wears and becomes thinner, the bushing 34 is driven by the arc-shaped sleeve 35 to slide along the support plate 33 and separate from the second protective pad 32. Thus, the second protective pad 32 can move upward through the elastic cord 37 and slide through the slots 311, thereby assisting the protective sheet 2 to work and avoiding the influence caused by the wear of the protective sheet 2.

[0024] The protection mechanism 21 includes two first protective pads 211. Clamping sleeves 212 are fixedly connected to one ends of the two first protective pads 211 close to each other. After the protective sheet 2 is worn and thinned by friction, the first protective pads 211 can be exposed, so as to work together with the protective sheet 2 to ensure the working effect of the protective sheet 2 and protect the protective sheet 2 to avoid the weakening of the performance of the protective sheet 2. Springs 214 are arranged at one ends of the two clamping sleeves 212 close to each other. Limit blocks 213 are fixedly connected to the outer surfaces of the two clamping sleeves 212. The two limit blocks 213 are respectively in contact with the two first protective pads 211. Lifting members 215 are arranged at one ends of the two first protective pads 211 close to each other. When the first protective pads 211 are located inside the first slots 22, they can be supported by the springs 214 and the clamping sleeves 212 to avoid the friction and shaking of the first protective pads 211. At the same time, by arranging the limit blocks 213, the limit blocks 213 are inside the second slots 23, which can prevent the limit blocks 213 from protruding too much and affecting the normal use.

[0025] The jacking member 215 includes a connecting frame 2151. Clamping plates 2154 are fixedly connected to both the front and back ends of the connecting frame 2151. Both of the two clamping plates 2154 are fixedly connected to the inner wall of the first slot 22. Two groups of sliding sleeves 2152 are fixedly connected to the inner wall of the connecting frame 2151. A vertical rod 2153 is arranged inside the connecting frame 2151. Both ends of the vertical rod 2153 are respectively arranged inside the two groups of sliding sleeves 2152. A pull rope 2155 is fixedly connected to the outer surface of the vertical rod 2153. One end of the pull rope 2155 away from the vertical rod 2153 penetrates through the connecting frame 2151 and extends to the outside of the connecting frame 2151. One end of the pull rope 2155 away from the vertical rod 2153 penetrates through the connecting disk 1 and extends to the outside of the connecting disk 1 and is fixedly connected to the second protective pad 32. By making the second protective pad 32 slide under friction to pull the vertical rod 2153, the vertical rod 2153 drives the connecting frame 2151 to open and squeeze the first protective pad 211, which can prevent the first protective pad 211 from being frictionally squeezed and the spring 214 from contracting, and can effectively support the first protective pad 211.

[0026] During use, after the protective sheet 2 is worn by friction and becomes thinner, the arc-shaped sleeve 35 can be driven to impact, so that the arc-shaped plate 35 can drive the clamping sleeve 34 to slide along the support plate 33, so that the clamping sleeve 34 can be separated from the second protective pad 32. After the clamping sleeve 34 is separated from the second protective pad 32, the second protective pad 32 can move upward through the elastic cord 37. After the second protective pad 32 moves upward, it slides through the slot 311 under friction and is limited by the slot 311 to assist the protective sheet 2 to work, avoiding the influence caused by the wear of the protective sheet 2. At the same time, after the protective sheet 2 is worn by friction and becomes thinner, the first protective pad 211 can be exposed, so as to work together with the protective sheet 2 to ensure the working effect of the protective sheet 2. The first protective pad 211 is inside the first slot 22 and is supported by the spring 214 and the clamping sleeve 212, which can effectively prevent the first protective pad 211 from shaking under friction and can effectively extend to cooperate with the protective sheet 2. At the same time, by setting the limiting block 213, the limiting block 213 is inside the second slot 23, which can prevent the limiting block 213 from protruding too much and affecting the normal use. When the second protective pad 32 slides under friction, the second protective pad 32 can pull the vertical rod 2153 through the pull rope 2155, so that the vertical rod 2153 can slide inside the sliding sleeve 2152, so that the movement of the vertical rod 2153 drives the connecting frame 2151 to open and squeeze the first protective pad 211, which can prevent the first protective pad 211 from being frictionally squeezed and the spring 214 from contracting, and can effectively support the first protective pad 211, so that the first protective pad 211 will not retract after being rubbed, ensuring the protection and auxiliary effect on the protective sheet 2 after the protective sheet 2 is rubbed.
