A brake chamber with high temperature resistance

Abstract

This utility model relates to the field of brake chamber technology, and more particularly to a brake chamber with high-temperature resistance. It includes a housing with an air inlet inside, a push rod inserted into the side wall of the housing, a diaphragm at one end of the push rod, a connecting block at the other end of the push rod, and a fixing ring on the inner side wall of the housing. This utility model utilizes a spiral cooling pipe. Coolant enters the spiral cooling pipe through an inlet pipe and enters the cooling tank through an outlet pipe. The coolant is then cooled by a liquid cooling plate, allowing for circulating heat dissipation. This improves the heat exchange efficiency within the housing and increases the heat contact area during heat dissipation. The heat dissipation diaphragm allows heat from the diaphragm's components to enter the outside of the spiral conveying pipe, improving the diaphragm's heat dissipation effect and extending its service life. The annular heat dissipation plate evenly distributes heat within the housing, reducing heat accumulation and preventing excessively high temperatures inside the housing.

Description

Technical Field

[0001] This utility model relates to the field of brake chamber technology, and in particular to a brake chamber with high temperature resistance. Background Technology

[0002] The brake chamber is the core actuator of the automotive braking system. It converts compressed air energy into mechanical thrust through a housing and diaphragm structure. Its interior is divided into two independent chambers by a rubber diaphragm, which connect the dual-chamber brake valve to the atmosphere. Under the action of air pressure, it pushes the push rod to achieve brake adjustment.

[0003] Because the brake chamber generates heat during operation, if the heat is not dissipated in time, it will cause a series of mechanical failures and affect the operation of the vehicle's braking system. In traditional brake chambers, the heat dissipation efficiency of the heat pipe and the brake chamber is low, and the contact area between the heat pipe and the heat is low, resulting in low heat exchange efficiency and affecting the braking effect of the vehicle. At the same time, it is difficult for heat to circulate in the traditional brake chamber, which reduces the cooling effect of the coolant and affects the heat exchange efficiency of the brake chamber. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low heat exchange efficiency and low coolant performance in the prior art, and to propose a brake chamber with high temperature resistance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A brake chamber with high-temperature resistance includes a housing with an air inlet inside. A push rod is inserted into the side wall of the housing, with a diaphragm at one end and a connecting block at the other end. A fixing ring and a spiral cooling pipe are also provided on the inner side wall of the housing. An input pipe is inserted into the bottom of the housing, and an output pipe is inserted into the side wall of the housing. The ends of the input and output pipes are respectively connected to the two ends of the spiral cooling pipe, and a cooling box is provided at the other end of the input and output pipes.

[0007] Preferably, a spring is sleeved on the outer wall of the push rod, and one end of the spring is connected to the outer wall of the push rod, while the other end of the spring is connected to the inner wall of the housing.

[0008] Preferably, the inner sidewall of the housing is provided with an annular heat dissipation plate, and the sidewall of the annular heat dissipation plate is provided with multiple heat dissipation holes in a circumferential linear pattern.

[0009] Preferably, the fixing ring has multiple unblocking holes, and a heat dissipation film is coaxially arranged in the unblocking holes.

[0010] Preferably, an input pump is coaxially provided at the end of the input pipe, and an output pump is coaxially provided at the end of the output pipe.

[0011] Preferably, the inner wall of the cooling box is provided with multiple liquid cooling plates arranged linearly, and a delivery pipe is inserted into the end of the cooling box.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model incorporates a spiral cooling pipe. Coolant enters the spiral cooling pipe through an inlet pipe and enters the cooling tank through an outlet pipe. The coolant is then cooled by a liquid cooling plate, allowing the coolant to circulate and dissipate heat. This improves the heat exchange efficiency within the casing and increases the heat contact area during heat dissipation.

[0014] 2. This utility model improves the heat dissipation effect of the diaphragm by setting a heat dissipation film, allowing the heat from the diaphragm accessories to enter the outside of the spiral conveying pipe, thus extending the service life of the diaphragm. By setting an annular heat dissipation plate, the heat inside the shell is evenly distributed, reducing heat accumulation and preventing the shell from becoming too hot. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A high-temperature resistant brake chamber includes a housing 1 with an air inlet 17 inside. A push rod 3 is slidably inserted into the side wall of the housing 1. A diaphragm 11 is coaxially fixed at the end of the push rod 3 by a clamping sleeve. A connecting block 2 is coaxially fixed at the other end of the push rod 3 by a bolt assembly. Gas enters the housing 1 through the air inlet 17, and the gas drives the diaphragm 11 to move, which in turn drives the push rod 3 to move. This configuration provides support for the push rod 3.

[0021] A spring 10 is fitted on the outer wall of the push rod 3, and the end of the spring 10 is fixedly connected to the outer wall of the push rod 3 by a hook. The other end of the spring 10 is fixedly connected to the inner wall of the housing 1 by a hook. When the push rod 3 moves, the spring 10 plays a role in resetting the push rod 3, ensuring the stability of the subsequent operation process.

[0022] The fixing ring 13 is fixedly installed on the inner side wall of the housing 1 by bolt assembly, and the annular heat sink 14 is fixedly installed on the inner side wall of the housing 1 by bolt assembly. The annular heat sink 14 has multiple heat dissipation holes in a circumferential linear pattern on its side wall. This arrangement facilitates the uniform distribution of heat inside the housing 1 and improves the heat exchange efficiency of the heat inside the housing 1.

[0023] The spiral cooling pipe 15 is fixedly installed on the inner side wall of the housing 1 by bolt assembly. The input pipe 4 is inserted into the bottom of the housing 1, and the output pipe 9 is inserted into the side wall of the housing 1. The input pump 5 is coaxially fixed at the end of the input pipe 4 by clamping sleeve, and the output pump 8 is coaxially fixed at the end of the output pipe 9 by clamping sleeve. This configuration provides output force for the coolant and prevents blockage during coolant input and output, which would reduce heat exchange efficiency.

[0024] The ends of the input pipe 4 and the output pipe 9 are connected to both ends of the spiral cooling pipe 15 through clamping sleeves, and the cooling box 6 is fixedly installed at the other end of the input pipe 4 and the output pipe 9 by bolt assembly. Coolant is contained in the cooling box 6. This arrangement improves the use effect of the coolant and increases the circulation rate of the coolant.

[0025] Multiple liquid cooling plates 16 are linearly arranged on the inner side wall of the cooling tank 6, and the delivery pipe 7 is inserted into the end of the cooling tank 6 through a clamping sleeve. The end of the delivery pipe 7 is equipped with a sealing valve. This arrangement improves the heat dissipation effect of the coolant in the cooling tank 6, allowing the operator to drain and replace the coolant through the sealing valve.

[0026] The bolt assemblies described above are all prior art. A bolt assembly includes a bolt and a threaded hole for threading two components together.

[0027] The nut is fitted onto the external thread of the bolt shank via its internal thread.

[0028] The functional principle of this utility model can be explained through the following operation methods:

[0029] Gas enters the housing 1 through the air inlet 17, which drives the push rod 3 to move. The push rod 3 drives the connecting block 2 to move. The spring 10 squeezes the push rod 3. The heat generated when the push rod 3 moves enters the spiral cooling pipe 15 through the annular heat sink 14. The input pump 5 causes the coolant to enter the spiral cooling pipe 15 through the input pipe 4. The coolant carries the heat through the spiral cooling pipe 15 to the output pipe 9. The output pump 8 causes the coolant to enter the cooling tank 6. The coolant is circulated and cooled through the liquid cooling plate 16. This arrangement increases the contact area between the coolant and the heat inside the housing 1, improving the overall heat exchange efficiency.

[0030] The heat generated when the diaphragm 11 moves is transferred to the outer wall of the spiral cooling tube 15 through the heat dissipation membrane 12. When the coolant needs to be replaced, the coolant in the cooling tank 6 is discharged and replaced through the delivery pipe 7. This arrangement improves the heat exchange effect of the diaphragm 11 and ensures the circulation effect of the coolant.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
