Description

Technical Field

[0001] The utility model relates to the technical field of wet brakes, in particular to a wet brake with good anti-leakage effect. Background Art

[0002] Wet brakes are a type of braking device commonly used in mechanical equipment. They use liquid to cool and lubricate the friction surface, and generate friction through the contact between the friction pad and the brake drum or brake disc to slow down or stop the moving object. The main components of wet brakes include brake friction discs, brake drums, brake drums, brake valves, brake linings, and brake fluid pumps. Among them, the brake friction disc and brake drum are usually mechanically connected to the engine output shaft and drive the wheels to rotate through a series of gears. When braking is required, brake fluid is pumped to the brake, causing the friction pad to come into close contact with the brake drum or brake disc, thereby generating friction to slow down or stop the vehicle.

[0003] Because wet brakes have the advantages of large braking torque, long service life, strong anti-fading ability, and maintenance-free, they are widely used in automobiles, tractors, ships, cranes, excavators, and railway systems.

[0004] In the "A wet brake with good anti-leakage effect" with the patent CN214888514U, a brake body is included, one end of which is provided with a fixing plate, and the other end of which is provided with a connecting plate, a sealing member is connected between the fixing plate and the brake body, and the sealing member includes an annular groove, a sealing gasket, a first annular protrusion, a second annular protrusion and a circular hole. The wet brake with good anti-leakage effect described in the utility model belongs to the field of wet brakes, and the sealing member is provided with an annular protrusion, and is matched by a snap-fit ​​method, so as to further improve the sealing effect and ensure the anti-leakage effect. The anti-leakage member is provided at the connection of the hydraulic pipe, so as to ensure the sealing effect of the connection between the hydraulic pipe and the brake, and ensure that the connection has a good anti-leakage effect, further improve the anti-leakage effect, and reduce the loss of hydraulic oil;

[0005] However, when the wet brake is used, the connecting plates at both ends of the brake are directly sealed and connected to the main body by screws, which is convenient for later use. However, the sealing effect of this connection method is general and cannot effectively prevent leakage, which will cause oil leakage during the later use of the wet brake, making it inconvenient for the later stable braking of the wet brake.

[0006] Therefore, we proposed that wet brakes with good anti-leakage effect can solve the above problems well. Utility Model Content

[0007] The utility model aims to provide a wet brake with good anti-leakage effect, so as to solve the problem raised by the above-mentioned background technology that in the current market, the connecting plates at both ends of the brake are directly sealed and connected to the main body by screws, which is convenient for later use. However, the sealing effect of this connection method is general and cannot effectively prevent leakage, which will cause oil leakage when the wet brake is used for braking, making it inconvenient for the stable braking use of the wet brake.

[0008] To achieve the above object, the utility model provides the following technical solutions: A wet brake with good anti-leakage effect, comprising a brake body, a positioning plate is installed through the internal groove, and the volume of the positioning plate is smaller than the volume of the brake body;

[0009] It also includes: a brake body, on the surface of which a circle of main positioning bolts is installed, a positioning plate, on the surface of which a circle of secondary positioning bolts is installed, and the circle of main positioning bolts and the circle of secondary positioning bolts are arranged at equal intervals, and the brake body, on the internal groove of which a sealing gasket is fitted, and the sealing gasket is made of fluororubber material, and the outer side of the sealing gasket is fitted with a connecting head, and the connecting head is sealed and installed on the inner end of the positioning plate.

[0010] Preferably, a circle of support rods is installed on the inner and outer sides of the brake body, and the support rods are arranged at equal intervals. The overall strength of the brake body can be increased by the circle of support rods.

[0011] Preferably, the brake body has grooves at both ends thereof and damping rods are installed therein, and the two damping rods have the same structure, and the outer ends of the two damping rods are connected to sealing plates, and the outer sides of the sealing plates are fitted with connecting heads. The two damping rods can be used to increase the anti-seismic buffering performance between the brake body and the positioning plate, thereby improving the overall service life of the brake body.

[0012] Preferably, the sealing plate has swing rods connected to its outer sides via movable shafts at both ends, and the two swing rods are inclined, and the outer ends of the two swing rods are connected to moving blocks via movable shafts, and the two moving blocks are slidably installed on both sides of the interior of the brake body; the brake body has a tension spring provided in an internal groove, and moving blocks are connected to both ends of the tension spring, and the two squeezed moving blocks can be elastically reset by the elastic force of the tension spring itself, thereby moving and resetting the sealing plate.

[0013] Preferably, the brake body has grooves at both the upper and lower ends, and arc blocks are installed by rotation of the return spring. The two arc blocks are both arc-shaped, and a row of arc grooves are connected to the outer sides of the two arc blocks. At the same time, the two rows of arc grooves are evenly spaced on the upper and lower sides of the positioning plate. The two arc blocks can be popped out into the two rows of arc grooves in turn by the elastic force of the two return springs themselves, and then the extruded moving positioning plate can be slidably limited.

[0014] Preferably, the inside of the two arc blocks are grooved with torsion springs, and the two torsion springs have the same structure, and the inner sides of the two torsion springs are wrapped and connected with rotating shafts, and the outer ends of the two rotating shafts extend through and extend to the outer sides of the upper and lower ends of the brake body. The two rotating rotating shafts can be elastically reset by the elastic force of the two torsion springs themselves to facilitate later reuse.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] (1) A positioning plate is installed through a groove in the inner part of the brake body, and then a connector is provided at the inner end of the positioning plate. When the connector extends into the inner part of the brake body, the sealing gasket increases the sealing between the brake body and the positioning plate, thereby preventing the brake body from leaking oil during the later braking operation, and improving the stability of the brake body;

[0017] (2) Two damping rods are arranged at both ends of the brake body, and then a sealing plate is connected to the outer ends of the two damping rods, and a connecting head is closely connected to the outer side of the sealing plate. After the positioning plate is squeezed and moved to the inside of the brake body, the connecting head squeezes the sealing plate to be squeezed and contracted through the two damping rods. At this time, the two damping rods can increase the seismic buffering performance between the brake body and the positioning plate, thereby improving the overall seismic performance of the brake body;

[0018] (3) Furthermore, by connecting swing rods at both ends of the sealing plate through movable shafts, and connecting moving blocks at the outer ends of the two swing rods through movable shafts, the moving blocks connected to the outer ends of the two swing rods can be driven to move when the sealing plate is squeezed and collided. At this time, the elastic force of the tension spring itself can be used to elastically reset the two squeezed moving blocks, so that the position of the sealing plate can be reset;

[0019] (4) By using the slots at both ends of the brake body to rotate and install the arc blocks through the return springs, when the positioning plate extends through the inside of the brake body, the two return springs will use their own elastic force to eject the two arc blocks into the two rows of arc grooves in turn, and then the positioning plate can be moved and limited, so as to avoid the phenomenon that the positioning plate becomes loose and falls off due to the vibration generated by use in the later stage, thereby improving the connection stability between the brake body and the positioning plate;

[0020] (5) Furthermore, a torsion spring is provided in the internal grooves of the two arc-shaped blocks, and then a rotating shaft is wound and connected to the inner side of the two torsion springs. When the brake body and the positioning plate need to be quickly disassembled and separated, it is only necessary to manually rotate the rotating shaft to drive the arc-shaped block and the arc-shaped groove to separate. At this time, the positioning plate can be quickly disassembled, assembled and replaced. Finally, the elastic force of the two torsion springs can be used to elastically reset the two rotating shafts. This is more practical and saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

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 oil seepage and oil leakage when the existing brake body 1 is used, discloses:

[0032] The brake body 1 has a groove inside which a positioning plate 2 is installed, and the volume of the positioning plate 2 is smaller than that of the brake body 1;

[0033] It also includes: a brake body 1, on the surface of which a circle of main positioning bolts 3 is installed, a positioning plate 2, on the surface of which a circle of secondary positioning bolts 4 is installed, and the circle of main positioning bolts 3 and the circle of secondary positioning bolts 4 are arranged at equal intervals, the brake body 1, the internal groove of which is fitted with a sealing gasket 5, and the sealing gasket 5 is made of fluororubber material, and the outer side of the sealing gasket 5 is fitted with a connecting head 6, and the connecting head 6 is sealed and installed on the inner end of the positioning plate 2.

[0034] The brake body 1 has a circle of support rods 17 installed inside and outside thereof, and the circle of support rods 17 are arranged at equal intervals.

[0035] like Figure 1-Figure 3 As shown, when the positioning plate 2 extends through the interior of the brake body 1, the sealing gasket 5 will increase the sealing between the brake body 1 and the positioning plate 2, avoiding oil leakage and seepage of the brake body 1 during braking in the later stage, thereby improving the overall sealing performance of the brake body 1.

[0036] Embodiment 2 is different from Embodiment 1 in that two damping rods 8 can be used to increase the anti-vibration buffering performance between the brake body 1 and the positioning plate 2, and discloses:

[0037] The brake body 1 has grooves at both ends thereof and damping rods 8 are installed therein, and the two damping rods 8 have the same structure, and the outer ends of the two damping rods 8 are connected to sealing plates 7, and the outer side of the sealing plate 7 is fitted with a connecting head 6, the sealing plate 7, the outer sides of both ends of the sealing plate 7 are connected to swing rods 9 through movable shafts, and the two swing rods 9 are inclined, and the outer ends of the two swing rods 9 are connected to moving blocks 10 through movable shafts, and the two moving blocks 10 are slidably installed on both sides of the interior of the brake body 1, the brake body 1 has a groove inside which a tension spring 11 is provided, and the two ends of the tension spring 11 are connected to the moving blocks 10.

[0038] like Figure 1-Figure 7 As shown, when the positioning plate 2 extends through and into the interior of the brake body 1, the connecting head 6 will squeeze and contract the sealing plate 7, and then the two damping rods 8 will increase the anti-seismic buffering performance between the brake body 1 and the positioning plate 2, thereby preventing the brake body 1 from being deformed and damaged due to squeezing and collision. When the sealing plate 7 is squeezed and contracted, the swing rod 9 connected to the movable shaft at its inner end will drive the two moving blocks 10 to squeeze and move their positions. At this time, the tension spring 11 will elastically reset the two squeezed moving blocks 10 through its own elastic force, and then reset the sealing plate 7. At this time, the sealing plate 7 can be sealed and fitted to the outside of the connecting head 6, which not only improves the sealing performance of the brake body 1, but also improves the stability of the brake body 1.

[0039] Embodiment 3 is different from Embodiment 2 in that the installed positioning plate 2 can be slidably limited, and discloses:

[0040] The brake body 1 has slots at both upper and lower ends, and an arc block 12 is rotatably installed by a reset spring 14. The two arc blocks 12 are both arc-shaped, and a row of arc grooves 13 are connected to the outer sides of the two arc blocks 12. At the same time, the two rows of arc grooves 13 are evenly spaced and arranged on the upper and lower sides of the positioning plate 2. The insides of the two arc blocks 12 are slotted with torsion springs 16, and the two torsion springs 16 have the same structure. The inner sides of the two torsion springs 16 are both wound and connected with a rotating shaft 15, and the outer ends of the two rotating shafts 15 extend through and extend to the outer sides of the upper and lower ends of the brake body 1.

[0041] like Figure 1-Figure 5 As shown, when the positioning plate 2 is installed inside the brake body 1, the two return springs 14 will use their own elastic force to pop the two arc blocks 12 into the two rows of arc grooves 13 in turn, and then the squeezed positioning plate 2 can be slidably limited to prevent the positioning plate 2 from loosening and falling off due to vibrations generated during use in the later stage. When the positioning plate 2 needs to be quickly disassembled and replaced, it is only necessary to manually rotate the rotating shaft 15 to drive the arc block 12 to separate from the arc groove 13, and then the positioning plate 2 can be quickly disassembled, assembled and replaced. Finally, the elastic force of the two torsion springs 16 can be used to elastically reset the positions of the two rotating shafts 15 after rotation, so as to facilitate later repeated use, improve practicality, and save time and effort.
