Description

[Technical field]

[0001] The utility model relates to the technical field of brake pads, in particular to the technical field of a firm heat dissipation type brake pad. [Background technology]

[0002] As the country attaches great importance to agricultural scale, there are more and more mechanized agricultural equipment, and the use of brake pads for harvesters is increasing day by day. Brake pads are also called brake leathers. In the field of mechanical equipment, brake pads are the most critical safety parts. The quality of all braking effects is determined by brake pads, so good brake pads are very important. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be coated to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure the quality. The insulation layer is composed of non-heat-conducting materials for the purpose of heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to produce friction, thereby achieving the purpose of mechanical equipment deceleration and braking. Traditional brake pads are made by high-temperature pressing of steel sheets and friction substrates. The steel sheets and friction substrates are usually flat-plate-shaped, so they have the disadvantages of insufficient adhesion and insufficient bite force. After a long period of use, this type of brake pad will cause the friction substrate to loosen or even fall off due to insufficient adhesion, so there are serious safety hazards.

[0003] To solve the problems raised in the background technology, publication number CN201730998U discloses a brake pad, including a steel sheet and a friction substrate bonded to the steel sheet, wherein the bonding surface of the steel sheet and the friction substrate is provided with a plurality of protruding columns protruding toward the friction substrate. By adopting the above technical solution, due to the effect of the protruding columns, when the steel sheet and the friction substrate are pressed and bonded at high temperature, the protruding columns are embedded in the friction substrate, thereby improving the adhesion between the steel sheet and the friction substrate, and effectively reducing the potential safety hazards caused by the loosening or falling off of the friction substrate due to insufficient adhesion of the brake pad. However, this structure still has the following shortcomings:

[0004] 1. Although the brake pad is embedded in the friction substrate through the protrusion, thereby improving the adhesion between the steel plate and the friction substrate, the protrusion is too firmly embedded in the friction substrate, which makes subsequent disassembly and installation inconvenient.

[0005] 2. The brake pad cannot adjust the distance between the steel plate and the friction substrate, and is not very practical.

[0006] 3. The brake pad lacks a heat dissipation structure, which results in the heat being unable to be discharged quickly, which will have a certain impact on the life of the brake pad and will affect the braking effect. [Utility Model Content]

[0007] The purpose of the utility model is to solve the problems in the prior art and to provide a strong heat dissipation brake pad, which can facilitate installation and disassembly between the back plate and the friction block, and can adjust the distance between the back plate and the friction block, and has the characteristics of good heat dissipation effect.

[0008] To achieve the above-mentioned purpose, the utility model proposes a strong heat-dissipating brake pad, comprising a back plate, a friction block, a connecting block, a fixing structure, a heat-insulating plate, a through hole, and a heat-conducting tube, wherein connecting blocks are symmetrically arranged at both ends of the back plate and the friction block, the back plate and the friction block are connected by a fixing structure, a heat-insulating plate is arranged between the back plate and the friction block, a through hole in a circular structure is opened in the middle of the heat-insulating plate, and a heat-conducting tube is arranged inside the through hole.

[0009] Preferably, the fixing structure includes a threaded rod and a fixing nut. The threaded rod is arranged above the connecting blocks at both ends of the back plate, passes through the connecting blocks at both ends of the friction block and extends upward. The back plate and the friction block are fixed on the threaded rod by means of a fixing nut thread.

[0010] Preferably, a ventilation slot in a cross-shaped structure is provided at the middle of the lower end surface of the back plate, the ventilation slot is connected to the through hole, and the ventilation slot is used in conjunction with the heat-conducting tube.

[0011] Preferably, the upper end surface of the friction block is provided with heat dissipation grooves, and the heat dissipation grooves are symmetrically arranged.

[0012] Preferably, an anti-noise strip is attached to the upper end surface of the friction block, and the anti-noise strip is located between the heat dissipation grooves.

[0013] Preferably, grooves with a square structure are provided on both sides of the upper end surface of the heat insulation plate, a heat sink is arranged inside the groove, and card slots are provided on both sides of the inner wall of the groove, and blocks matching the card slots are provided on both sides of the heat sink, and the heat sink is connected to the card slot through the card blocks.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model can facilitate installation and disassembly between the back plate and the friction block by setting a fixing structure. The connection between the back plate and the friction block can be achieved through the threaded rod and the fixing nut, and the threaded tightening installation method is adopted to facilitate the disassembly of the back plate and the friction block, which not only improves the firmness, but also can adjust the distance between the back plate and the friction block, which is more practical and solves the problem of inconvenient installation and disassembly of the steel plate and the friction substrate and the inability to adjust the distance.

[0016] 2. The utility model can improve the overall heat dissipation effect of the brake pad through the coordinated use of the heat insulation plate, the heat conduction tube, the ventilation groove, the heat sink and the heat sink. When the brake pad generates heat through mutual friction during braking, the heat conduction tube on the heat insulation plate absorbs the heat and guides the heat into the ventilation groove, and then discharges the heat from the ventilation groove, so as to discharge the heat inside the brake pad, and the heat sink can play a role of secondary heat dissipation to avoid a small amount of heat not being discharged and affecting the braking effect, and the heat sink on the friction block can dissipate the heat to the outside of the brake pad, thereby achieving the purpose of combining internal and external heat dissipation, improving the heat dissipation effect, and solving the problem that the brake pad cannot discharge heat and affects braking.

[0017] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

The connection between the back plate 1 and the friction block 2 can be achieved through the threaded rod 41 and the fixing nut 42, and the threaded tightening installation method makes it easy to disassemble the back plate 1 and the friction block 2, which not only improves the firmness, but also can adjust the distance between the back plate 1 and the friction block 2, and is more practical.
