Description

Technical Field

[0001] This utility model belongs to the field of rocker assembly technology, and specifically relates to a train brake rocker assembly. Background Technology

[0002] The train brake rocker assembly is a crucial component of the train braking system, primarily used to transmit and amplify braking force to ensure safe stopping of the train. It typically consists of a rocker, connecting rod, lever, and fulcrum, mechanically transmitting the force applied by the driver to the brake pedal to the brakes of each wheel. During prolonged use, the rocker and connecting rod undergo repeated mechanical movements, leading to wear and tear, reduced braking force transmission efficiency, and compromised braking performance. The conventional solution is to periodically inspect and lubricate the brake rocker assembly to ensure the proper functioning of all moving parts. However, this method has drawbacks: regular maintenance requires significant manpower, resources, and time; and delayed maintenance can lead to malfunctions during use. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a train brake rocker assembly to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a train brake rocker assembly, comprising: a rocker assembly body, a lubrication box and an oil-absorbing sponge, wherein a lubrication box of the same specification is installed on each of the left and right sides of the rocker assembly body, and a pressure boosting chamber is provided inside the upper part of the lubrication box;

[0005] Below the pressurization chamber is an oil storage chamber for storing lubricating oil. Two sets of springs for resetting the pressing plate are installed on the front and rear sides of the top of the lubrication box. A clamping plate is installed on the left and right sides of the main body of the rocker assembly. An oil-absorbing sponge for absorbing lubricating oil is placed inside the clamping plate. Several sets of sponge columns for guiding the lubricating oil to the inner side of the clamping plate are provided on the inner side of the oil-absorbing sponge.

[0006] In a preferred embodiment, the top of the lubrication box is provided with a pressing plate that drives the pressure plate to move inside the pressure chamber. The top of the rocker assembly body is provided with a rocker arm, and a rotating disk is provided below the rocker arm. The rotating disk is installed between two sets of clamping plates, and the inner sides of the two sets of clamping plates are in contact with the side of the rotating disk. By rotating the rotating disk inside the two sets of clamping plates, the lubricating oil inside the socket can be carried out and applied to the inner side of the clamping plates as the rotating disk rotates, thereby achieving a lubrication effect.

[0007] In a preferred embodiment, the clamping plate has several sets of insertion holes through its side for inserting sponge pillars. The radius and depth of the insertion holes match the radius and width of the sponge pillars. After the oil-absorbing sponge is saturated with lubricating oil, the lubricating oil diffuses inside the oil-absorbing sponge and enters the insertion holes through the several sets of sponge pillars. Then, under the rotation of the rotating disk, the lubricating oil inside the insertion holes is carried out and applied to the inner side of the clamping plate as the rotating disk rotates.

[0008] In a preferred embodiment, the sponge column and the oil-absorbing sponge are an integral structure, the outer side of the clamping piece is recessed inward to form a placement groove, the oil-absorbing sponge is glued inside the placement groove, and the thickness of the oil-absorbing sponge matches the depth of the placement groove.

[0009] In a preferred embodiment, the lubrication box has a filling port on the rear side of the top, the pressure chamber has a connecting port one through the center of the top, and the pressure chamber has a connecting port two through the center of the bottom.

[0010] In a preferred embodiment, a connecting rod is provided inside the communication port, the top of the connecting rod is glued to the center of the bottom of the pressing plate, and the bottom of the connecting rod is glued to the center of the top of the pressure plate.

[0011] In a preferred embodiment, the length and width of the pressure plate match the length and width of the pressure chamber, the side of the pressure plate contacts the inner wall of the pressure chamber, and the pressure plate is made of rubber.

[0012] In a preferred embodiment, two sets of oil guide pipes are installed through the inner wall of the oil storage chamber on the side near the rocker assembly body, and two sets of nozzles are installed on the side of the lubrication box near the rocker assembly body. The nozzles are embedded inside the rocker assembly body and are horizontally opposite to the oil-absorbing sponge.

[0013] In a preferred embodiment, the side of the oil guide pipe near the oil reservoir is located below the lubricating oil interface, and the side of the oil guide pipe near the nozzle is connected to the nozzle. By pressing down the pressing plate, the pressure plate moves inside the pressure chamber, and the side of the pressure plate contacts the inside of the pressure chamber. Since the pressure plate is made of rubber, it can generate a good pressure boosting effect inside the pressure chamber. The pressure is transmitted to the inside of the oil reservoir through the second connecting port, and then the two sets of oil guide pipes guide the lubricating oil to the nozzle. The nozzle sprays the lubricating oil into the oil-absorbing sponge, thereby greatly reducing the complexity of the oil spraying operation and improving the convenience of maintenance.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting up a pressing plate, a booster plate, and an oil guide pipe, the pressing plate is squeezed to drive the booster plate to move downward inside the booster chamber, thereby increasing the pressure inside the booster chamber. Then, through the second connecting port, the pressure inside the oil storage chamber is increased, which in turn allows the lubricating oil to be transported to the nozzle through two sets of oil guide pipes. The nozzle then sprays the lubricating oil into the oil-absorbing sponge, saturating the oil-absorbing sponge. After pressing, the pressing plate is returned to its original position by two sets of springs. By setting up an oil-absorbing sponge and sponge columns, the saturated oil-absorbing sponge applies lubricating oil to several sets of insertion holes through several sets of sponge columns. As the rotating disk rotates in the middle of the clamping plate, the lubricating oil is applied to the inner side of the clamping plate, thereby achieving rapid and timely lubrication between the rotating disk and the clamping plate, reducing friction loss.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4 A train brake rocker assembly includes: a rocker assembly body 100, a lubrication box 300, and an oil-absorbing sponge 400. A lubrication box 300 of the same specification is installed on each of the left and right sides of the rocker assembly body 100. A pressure boosting chamber 320 is provided inside the upper part of the lubrication box 300.

[0026] Two sets of springs 350 for resetting the pressing plate 330 are installed on the front and rear sides of the top of the lubrication box 300. A clamping plate 200 is installed on the left and right sides inside the rocker assembly body 100. An oil-absorbing sponge 400 for absorbing lubricating oil is placed inside the clamping plate 200. Several sets of sponge columns 410 are provided inside the oil-absorbing sponge 400 to guide the lubricating oil to the inner side of the clamping plate 200.

[0027] The top of the lubrication box 300 is equipped with a pressing plate 330 that drives the pressure plate 340 to move inside the pressure chamber 320. Below the pressure chamber 320 is an oil storage chamber 310 for storing lubricating oil. The top of the rocker assembly body 100 is equipped with a rocker arm, and below the rocker arm is a rotating disk 110. The rotating disk 110 is installed between two sets of clamping plates 200. The inner sides of the two sets of clamping plates 200 are in contact with the side of the rotating disk 110. By rotating the rotating disk 110 inside the two sets of clamping plates 200, the lubricating oil inside the insertion hole 220 can be carried out and applied to the inner side of the clamping plates 200 as the rotating disk 110 rotates, thereby achieving a lubrication effect.

[0028] The clamping plate 200 has several sets of insertion holes 220 through its side for inserting sponge pillars 410. The radius and depth of the insertion holes 220 match the radius and width of the sponge pillars 410. After the oil-absorbing sponge 400 is saturated with lubricating oil, the lubricating oil diffuses inside the oil-absorbing sponge 400 and enters the insertion holes 220 through the several sets of sponge pillars 410. Then, under the rotation of the rotating disk 110, the lubricating oil inside the insertion holes 220 is carried out and applied to the inner side of the clamping plate 200 as the rotating disk 110 rotates.

[0029] The sponge column 410 and the oil-absorbing sponge 400 are integrated into one structure. The outer side of the clamping piece 200 is recessed inward to form a placement groove 210. The oil-absorbing sponge 400 is glued inside the placement groove 210, and the thickness of the oil-absorbing sponge 400 matches the depth of the placement groove 210.

[0030] A filling port is provided on the rear side of the top of the lubrication box 300, a connecting port 1 is provided through the center of the top of the pressure chamber 320, and a connecting port 2 is provided through the center of the bottom of the pressure chamber 320.

[0031] The connecting port is equipped with a connecting rod. The top of the connecting rod is glued to the center of the bottom of the pressing plate 330, and the bottom of the connecting rod is glued to the center of the top of the pressure plate 340.

[0032] The length and width of the booster plate 340 match the length and width of the booster chamber 320. The side of the booster plate 340 contacts the inner wall of the booster chamber 320. The booster plate 340 is made of rubber.

[0033] Two sets of oil guide pipes 360 are installed through the inner wall of the oil storage chamber 310 near the rocker assembly body 100. Two sets of nozzles are installed in the lubrication box 300 near the rocker assembly body 100. The nozzles are embedded inside the rocker assembly body 100 and are horizontally opposite to the oil-absorbing sponge 400.

[0034] The side of the oil guide pipe 360 ​​near the oil reservoir 310 is below the lubricating oil interface. The side of the oil guide pipe 360 ​​near the nozzle is connected to the nozzle. By pressing down the pressing plate 330, the pressure plate 340 is moved inside the pressure chamber 320. The side of the pressure plate 340 contacts the inside of the pressure chamber 320. Since the pressure plate 340 is made of rubber, it can generate a good pressure boosting effect inside the pressure chamber 320. The pressure is transmitted to the inside of the oil reservoir 310 through the connecting port 2. Then, the two sets of oil guide pipes 360 guide the lubricating oil to the nozzle. The nozzle sprays the lubricating oil into the oil-absorbing sponge 400, which greatly reduces the complexity of the oil spraying operation and improves the convenience of maintenance.

[0035] Example 1: Please refer to Figures 1 to 4 In actual use, the rocker arm at the top of the rocker arm assembly body 100 is connected and fixed to the rotating disk 110 inside the rocker arm assembly body 100. The rotating disk 110 is held between two sets of clamping plates 200. By operating the rocker arm, the rotating disk 110 is rotated, thereby controlling the train's brakes (the principle and internal structure of the rocker arm assembly body 100 controlling the train are existing technologies and will not be described in detail here). During the rotation of the rotating disk 110, the rotating disk 110 interacts with the inner sides of the two sets of clamping plates 200. Repeated friction can easily cause wear on the rotating disk 110 and the clamping plate 200 after prolonged use. In actual use, the pressing plate 330 on the top of the lubrication box 300 on either side can be pressed to move the pressing plate 330 downward and squeeze the two sets of springs 350, causing the springs 350 to contract and store force. At this time, the pressing plate 330 drives the pressure plate 340 inside the pressure chamber 320 to move downward inside the pressure chamber 320 through the connecting rod below it, thereby increasing the pressure inside the pressure chamber 320.

[0036] After the pressure inside the pressurization chamber 320 increases, the pressure inside the oil storage chamber 310 increases through the second connecting port. Then, the lubricating oil is delivered to the two sets of nozzles through the two sets of oil guide pipes 360. The lubricating oil is sprayed into the oil-absorbing sponge 400 bonded to the inner side of the clamping plate 200 through the nozzles. After the oil-absorbing sponge 400 fully absorbs the lubricating oil and reaches saturation, the lubricating oil diffuses inside the oil-absorbing sponge 400 and diffuses into the rod assembly insertion hole 220 through several sets of sponge columns 410 inside the oil-absorbing sponge 400. When the rocker arm drives the rotating disk 110 to rotate, the two sides of the rotating disk 110 rub against the inner sides of the two sets of clamping plates 200, thereby bringing the lubricating oil out from the several sets of insertion holes 220 and evenly coating the inner side of the clamping plate 200. This achieves the lubrication effect between the clamping plate 200 and the rotating disk 110. The final effect is to greatly improve the lubrication efficiency between the clamping plate 200 and the rotating disk 110. Moreover, the lubrication method is simple, fast and convenient to use.

[0037] Example 2: Please refer to Figure 2 As can be seen from the operation in Example 1, pressing the press plate 330 once will perform one oil spraying operation. After one oil spraying is completed, the two sets of springs 350 will rebound and push the press plate 330 upward, thereby driving the pressure plate 340 to reset inside the pressure chamber 320 through the connecting rod. Then, the press plate 330 can be pressed down repeatedly to achieve multiple oil spraying operations. Therefore, the operation process is simple. When the lubricating oil inside the oil storage chamber 310 is exhausted, lubricating oil can be added to the oil storage chamber 310 through the filling port, so that the filling process is simple and convenient. Therefore, maintenance is quick and convenient.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
