Description

Technical Field

[0001] The utility model relates to the technical field of wet brakes, in particular to a wet brake with a cooling mechanism. Background Art

[0002] Wet brakes are a type of brake commonly used in mechanical equipment. They use liquid to resist and convert into heat to slow down or stop a moving object. Wet brakes are mainly used in large vehicles, mechanical equipment and railway systems. Their working principle is to generate braking force by wetting friction materials and use liquid to cool and lubricate the friction surface. They are mainly composed of brake friction discs, brake drums, brake valves, brake linings and brake fluid pumps. Brake friction discs and brake drums are usually mechanically connected to the engine output shaft and drive the wheels through a series of gears.

[0003] Wet brakes have many features such as large braking torque, long service life, strong anti-fading ability, and maintenance-free. Its fully enclosed structure prevents mud, water, and oil from entering, and brakes stably. At the same time, wet brakes use hydraulic drive and oil circulation cooling, which has good heat dissipation performance, reduces maintenance, and extends service life;

[0004] In the "A wet brake with a cooling mechanism" patent disclosed as CN220354348U, a wet brake body is included, a mounting hole is provided on the wet brake body, and a hydraulic rotary joint is built into the wet brake body. The wet brake with a cooling mechanism is provided with an opening and closing assembly, which can rotate the opening and closing cover, the oil inlet hole and the perforation after use. When the perforation is rotated to communicate with the corresponding oil outlet, the opening and closing cover no longer blocks the oil outlet, so that the cooling oil in the cooling chamber can flow out from the oil outlets at multiple positions together, thereby improving the efficiency of oil drainage. At the same time, oil drainage is performed at each position, and the effect of the cooling oil becoming viscous and affecting the thoroughness of oil drainage is avoided as much as possible. The oil poured into the cooling chamber again is also new cooling oil, thereby ensuring the cooling effect on the wet brake body and solving the problem of inconvenience in replacing the cooling oil.

[0005] However, when the above-mentioned wet brake is used for braking, because the conventional wet brake is basically cooled by coolant, most of the conventional coolants are fed and discharged through a single oil inlet and oil outlet hole, which prolongs the oil change speed, thereby causing the cooling efficiency of the coolant, and no cooling mechanism is provided to assist the stable cooling of the wet brake, which is not convenient for the stable braking use of the wet brake in the later stage;

[0006] Therefore, we proposed that a wet brake with a cooling mechanism can solve the above problems well. Utility Model Content

[0007] The utility model aims to provide a wet brake with a cooling mechanism to solve the problem in the current market proposed by the above background technology that traditional wet brakes are basically cooled by coolant during use, but most of the traditional coolants are fed and discharged through a single oil inlet and oil outlet hole, which prolongs the oil change speed, thereby causing the cooling efficiency of the coolant, and no cooling mechanism is provided to assist the stable cooling use of the wet brake, which is inconvenient for the stable braking use of the wet brake in the later stage.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A wet brake with a cooling mechanism, comprising a brake body, a cover plate is installed through a groove on the upper part of the brake body, and the outer end of the cover plate extends through the top outside of the brake body, and the diameter of the brake body is greater than the diameter of the cover plate;

[0009] It also includes: a brake body, both ends of which are slotted and penetrated by pressure rods, and the outer ends of the two pressure rods extend to the outer sides of the upper ends of the brake body, and the two pressure rods are symmetrically arranged about the vertical center line of the brake body, a cover plate, the inner end of which is screwed with a heat sink, and a row of heat sink fins are evenly spaced on the outer side of the heat sink, and a heat sink net is corresponding to the outer side of the row of heat sink fins, and the heat sink net is slotted and arranged on the inner side of the bottom of the brake body.

[0010] Preferably, the brake body has two damping rods installed in the internal grooves, and the two damping rods have the same structure, and the outer sides of the two damping rods are connected to the outer sides of both ends of the cover plate through buffer springs. The two damping rods can increase the seismic buffering performance between the brake body and the cover plate to prevent the cover plate from being deformed and damaged due to vibration and collision.

[0011] Preferably, the cover plate has extrusion rods connected to its inner ends via movable shafts at both ends, and the two extrusion rods are inclined, and the outer ends of the two extrusion rods are connected to moving blocks via movable shafts, and the two moving blocks are slidably installed at the inner ends of the brake body; the brake body has grooves at both ends thereof provided with tension springs, and the two tension springs have the same structure, and the outer ends of the two tension springs are connected to moving blocks, and the positions of the two moving blocks after being extruded and pulled can be elastically reset by the elastic force of the two tension springs themselves.

[0012] Preferably, the brake body has grooves at both ends thereof through which limit rods are slidably installed, and the inner ends of the two limit rods extend through the brake body to the two limit grooves, and the two limit grooves are opened at the two inner ends of the cover plate, and the outer sides of the two pressing rods are connected to rotating gears through rack meshing, and the outer sides of the two rotating gears are also connected to the limit rods through rack meshing, so that the cover plate installed through can be clamped and positioned to prevent the cover plate from loosening and falling off during later use.

[0013] Preferably, the inside of the two rotating gears are grooved with torsion springs, and the outer ends of the two torsion springs are connected to the two inner ends of the brake body, so that the positions of the two rotating gears can be elastically reset after rotation by the elastic force of the two torsion springs themselves.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] (1) A cover plate is provided in the internal groove of the brake body, and then a row of heat dissipation fins are installed at the inner end of the cover plate through a heat dissipation seat. The heat accumulated inside the brake body can be transported to the outside of the brake body through the heat dissipation net through the row of heat dissipation fins, thereby avoiding heat accumulation inside the brake body and affecting its stable heat dissipation and cooling use in the later stage, thereby improving the cooling efficiency of the brake body;

[0016] (2) Furthermore, by installing damping rods at both ends of the brake body, and then connecting the cover plate to the outer ends of the two damping rods through buffer springs, the two damping rods can increase the anti-seismic buffering performance between the brake body and the cover plate, thereby avoiding deformation and damage of the brake body and the cover plate due to extrusion and collision, thereby increasing the service life of the brake body;

[0018] (4) The limit rods are installed by sliding through the grooves at both ends of the brake body, and then the inner ends of the two limit rods are extended through the brake body to the inner ends of the cover plate. Then, the installed cover plate can be positioned and fixed, so as to avoid the cover plate from loosening and falling off due to the vibration generated by the use of the brake body in the later stage, thereby improving the stability of the use of the brake body;

[0019] (5) Furthermore, when the brake body and the cover plate need to be quickly disassembled, assembled and replaced, the two pressing rods are manually pressed to retract and move, and then the racks arranged on the outside of the two pressing rods will simultaneously drive the two rotating gears to rotate, and then the two rotating gears will also simultaneously drive the two limit rods to retract and move through the two racks. At this time, the cover plate can be quickly disassembled, assembled and replaced, and finally the elastic force of the two torsion springs can be used to elastically reset the positions of the two rotating gears after rotation, so as to facilitate later reuse.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] This utility provides the following technical solutions:

[0031] Embodiment 1, in order to solve the problem of poor cooling effect of the existing brake body 1, discloses:

[0032] The brake body 1 has a cover plate 2 installed through a groove on the upper part of the inner part, and the outer end of the cover plate 2 extends through and extends to the outer side of the top of the brake body 1, and the diameter of the brake body 1 is larger than the diameter of the cover plate 2;

[0033] It also includes: a brake body 1, both ends of which are slotted and penetrated by pressing rods 3, and the outer ends of the two pressing rods 3 extend to the outer sides of the upper ends of the brake body 1, and the two pressing rods 3 are symmetrically arranged about the vertical center line of the brake body 1, and a cover plate 2, the inner end of which is screwed with a heat sink 10, and the outer side of the heat sink 10 is provided with a row of heat sink fins 11 at equal intervals, and the outer side of the row of heat sink fins 11 corresponds to a heat sink 9, and the heat sink 9 is slotted and arranged on the inner side of the bottom of the brake body 1.

[0034] like Figure 1-Figure 5 As shown, when the brake body 1 is in use for braking, the heat sink 10 will transfer the heat accumulated inside the brake body 1 to the heat sink 9 through a row of heat sink fins 11 and discharge it to the outside of the brake body 1, thereby avoiding heat accumulation inside the brake body 1 and affecting the subsequent cooling efficiency, thereby improving the cooling efficiency of the brake body 1.

[0035] Embodiment 2 is different from Embodiment 1 in that the cover plate 2 used can be shock-proof and buffered, so as to facilitate the reciprocating heat dissipation cooling of the brake body 1 in the later stage, and discloses:

[0036] The brake body 1 has two damping rods 4 installed in the internal grooves, and the two damping rods 4 have the same structure, and the outer sides of the two damping rods 4 are connected to the outer sides of the two ends of the cover plate 2 through buffer springs 5. The cover plate 2 has extrusion rods 6 connected at both ends of the inner side through movable shafts, and the two extrusion rods 6 are inclined, and the outer ends of the two extrusion rods 6 are connected to moving blocks 7 through movable shafts, and the two moving blocks 7 are slidably installed at the inner ends of the brake body 1. The brake body 1 has tension springs 8 installed in the internal grooves at both ends, and the two tension springs 8 have the same structure, and the outer ends of the two tension springs 8 are connected to moving blocks 7.

[0037] like Figure 1-Figure 4 As shown, when the brake body 1 generates vibration during use, the two damping rods 4 will increase the anti-seismic buffering performance between the brake body 1 and the cover plate 2 through the two buffer springs 5, so as to prevent the cover plate 2 from being deformed and damaged due to the vibration generated during use. When the brake body 1 vibrates, the cover plate 2 will drive the two extrusion rods 6 to squeeze the two moving blocks 7 to move their positions through the movable shaft, and then the elastic force of the two tension springs 8 can be used to elastically reset the positions of the two moving blocks 7 after the extrusion and movement, and then the heat sink 10 will drive a row of heat sink fins 11 to contact the heat sink net 9, so as to realize reciprocating heat dissipation of heat, thereby improving the stability of the use of the brake body 1.

[0038] Embodiment 3 is different from Embodiment 2 in that the cover plate 2 can be quickly disassembled and replaced, which is more practical and discloses:

[0040] like Figure 1-Figure 8As shown, when the cover plate 2 needs to be quickly disassembled and replaced, it is only necessary to manually press the two pressing rods 3 to retract and move them. At this time, the racks 15 arranged on the outside of the two pressing rods 3 will simultaneously drive the two rotating gears 12 to rotate, and then the two rotating gears 12 will also simultaneously drive the two limiting rods 13 to retract and move through the racks 15, so that the two limiting rods 13 are separated from the limiting grooves 14, and finally, the elastic force of the two torsion springs 16 themselves can be used to elastically reset the positions of the two rotating gears 12 after rotation, so that the cover plate 2 can be quickly replaced and disassembled, which is more practical and more time-saving and labor-saving to operate.
