Description

Technical Field

[0001] The utility model relates to the technical field of friction plates, in particular to an alarm mechanism for friction plates. Background Art

[0002] Friction plate refers to a component consisting of a core and a friction lining or friction material layer, which is widely used in the fields of mechanical engineering, mechanical parts and clutches. It is composed of friction material and adhesive, and mainly generates friction during braking, thereby achieving the purpose of vehicle deceleration and braking.

[0003] Temperature is an important factor affecting the friction coefficient of the friction plate. During the friction process, the temperature of the friction plate rises rapidly, generally when the temperature reaches above 200°C, the friction coefficient begins to decrease. At this time, some friction plates do not have an alarm mechanism, so the owner cannot detect that the friction plate is overheating. Once the temperature of the friction plate continues to rise, the friction plate will gradually coke or even burn, creating a safety hazard. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an alarm mechanism for a friction plate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An alarm mechanism for a friction plate, comprising a friction plate body, the friction plate body being arranged on a mounting seat, the mounting seat being located on an upper surface, and an alarm mechanism being installed on one side of the friction plate body, and a low melting point alloy plate being installed on the alarm mechanism;

[0007] The alarm mechanism includes a short-circuit alarm, which is installed on one side of the mounting seat. Mounting heads are symmetrically arranged on the side walls on both sides of the short-circuit alarm. Connecting heads are symmetrically arranged on the surface of the side wall adjacent to the mounting head of the short-circuit alarm, and low-melting-point alloy plates are installed on the connecting heads on both sides.

[0008] In addition, a preferred structure is that second through holes are symmetrically opened on both sides of the low-melting-point alloy plate body, and a surface of one side of the low-melting-point alloy plate body is in contact with a side wall surface of the friction plate body.

[0009] In addition, a preferred structure is that the connectors are all provided with a first through hole, the aperture of the first through hole is consistent with the aperture of the second through hole, and a first fixing component is installed at the through hole of the connector and the low-melting-point alloy plate.

[0010] In addition, a preferred structure is that a placement groove is opened in the middle of the surface of one side of the mounting seat body, and the low-melting-point alloy plate is arranged in the placement groove.

[0011] In addition, a preferred structure is that the mounting seat is symmetrically provided with mounting plates on one side wall of the placement groove, and alarm mechanisms are installed on the mounting plates on both sides.

[0012] In addition, a preferred structure is that the mounting heads on both sides of the alarm mechanism are mounted on a mounting plate, mounting holes are provided on the mounting heads, and second fixing components are installed at the mounting holes.

[0013] The beneficial effects of the utility model are as follows: by installing an alarm mechanism on one side of the mounting seat, once the temperature of the friction plate body is too high due to friction, once the temperature exceeds 230°C, the low-melting-point alloy plate in contact with it on one side will fuse, thereby causing the short-circuit alarm to sound an alarm, quickly reminding the user that the temperature of the friction plate body is too high and needs to be cooled in time, effectively preventing the friction plate body from continuing to heat up, thereby causing a dangerous situation of burning and coking. The alarm mechanism can effectively improve the safety of the friction plate body and facilitate timely reminders to the user. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

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

[0020] Reference Figure 1-4 , an alarm mechanism for a friction plate, comprising a friction plate body 1, the friction plate body 1 is arranged on a mounting seat 2, the mounting seat 2 is located on the upper surface, an alarm mechanism 3 is installed on one side of the friction plate body 1, and a low melting point alloy plate 4 is installed on the alarm mechanism 3;

[0021] The alarm mechanism 3 includes a short-circuit alarm 31, which is installed on one side of the mounting seat 2. Mounting heads 33 are symmetrically arranged on the side walls on both sides of the short-circuit alarm 31. Connecting heads 32 are symmetrically arranged on the side wall surface adjacent to the mounting head 33 of the short-circuit alarm 31, and low-melting-point alloy plates 4 are installed on the connecting heads 32 on both sides.

[0022] Among them, second through holes 41 are symmetrically opened on both sides of the low-melting-point alloy plate 4. One side surface of the low-melting-point alloy plate 4 is in contact with the side wall surface of the friction plate body 1. The low-melting-point alloy plate 4 can contact the friction plate body 1. Once the temperature of the friction plate body 1 is high, the low-melting-point alloy plate 4 in contact with it will melt under the action of heat conduction.

[0023] In addition, a first through hole 321 is opened on the connecting head 32, and the aperture of the first through hole 321 is consistent with the aperture of the second through hole 41. A first fixing component 5 is installed at the through hole of the connecting head 32 and the low-melting-point alloy plate 4. The first fixing component 5 facilitates fixing the low-melting-point alloy plate 4 on the connecting head 32.

[0024] Moreover, a placement groove 21 is opened in the middle of the surface of one side of the mounting seat 2, and the low-melting-point alloy plate 4 is arranged in the placement groove 21. The placement groove 21 facilitates the low-melting-point alloy plate 4 to be placed therein so as to fit with the friction plate body 1.

[0025] In addition, the mounting seat 2 is symmetrically provided with a mounting plate 22 on one side wall of the placement groove 21, and the alarm mechanism 3 is installed on the mounting plates 22 on both sides. The mounting heads 33 on both sides of the alarm mechanism 3 are installed on the mounting plates 22, and the mounting heads 33 are provided with mounting holes 331. The second fixing component 6 is installed at the mounting hole 331. The second fixing component 6 can install the short circuit alarm 31 on the mounting plate 22.

[0026] In the present embodiment, in order to timely detect whether the temperature of the friction plate body 1 is too high, an alarm mechanism 3 is installed. First, the low-melting point alloy plate 4 is cut into a suitable length and a second through hole 41 is punched. Then, the low-melting point alloy plate 4 is fixed to the connector 32 by the first fixing component 5. Then, the short-circuit alarm 31 is installed on the mounting plate 22 so that one side surface of the low-melting point alloy plate 4 can fit with the friction plate body 1. Then, the short-circuit alarm 31 can be turned on. Because the material of the low-melting point alloy plate 4 is conductive, the connectors 32 on both sides of the short-circuit alarm 31 are energized to form a loop with the low-melting point alloy plate 4. The low-melting point alloy plate 4 is an alloy made of elements including but not limited to bismuth, lead, tin and cadmium, and its melting point is about 230°C. The short-circuit alarm 31 is a prior art and a technical means well known to personnel in the field of short-circuit alarm 31, so its structure does not need to be elaborated.

[0027] Once the temperature of the friction plate body 1 is too high and exceeds 230°C, the low-melting-point alloy plate 4 on one side will melt and become disconnected, causing the formed circuit to short-circuit. At this time, the short-circuit alarm 31 sends out an alarm message, so that the user can know that the temperature of the friction plate body 1 is too high and needs to be cooled. The short-circuit alarm 31 is detachable, and a new low-melting-point alloy plate 4 can be replaced by removing the second fixing component 6 and the first fixing component 5.

[0028] In the utility model, an alarm mechanism 3 is installed on one side of the mounting seat 2, so that once the temperature of the friction plate body 1 is too high due to friction, once the temperature exceeds 230°C, the low-melting-point alloy plate 4 arranged on one side in contact with it will fuse, thereby causing the short-circuit alarm 31 to sound an alarm, quickly reminding the user that the temperature of the friction plate body 1 is too high and needs to be cooled in time, effectively preventing the friction plate body 1 from continuing to heat up, thereby causing a dangerous situation of combustion and coking. The alarm mechanism 3 can effectively improve the safety of the friction plate body 1 and facilitate timely reminders to the user.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
