Description

Technical Field

[0001] The utility model relates to the technical field of brake air chambers, in particular to a brake air chamber with a reinforced structure. Background Art

[0002] The brake chamber is usually a key component in the braking system of a car, truck or other vehicle, which plays the role of converting air pressure into mechanical force. When the driver presses the brake pedal, the brake system releases compressed air into the brake chamber, and the pressure increases, causing the piston or other mechanical device in the chamber to move, thereby applying braking force to the camshaft in the vehicle's brake mechanism to rotate and realize braking movement, slowing down or stopping the vehicle.

[0003] The existing brake air chambers on the market often use a single support rod to withstand the pressure transmitted from the air pressure in the air chamber for forward and backward movement. The connection structure of the support rod is relatively fragile. After multiple movements, the connection is not stable enough and the support rod is easy to deviate from the set movement axis, thereby affecting the transmission of the braking mechanism. In addition, the part of the support rod outside the air chamber is easily deformed, broken, etc. when impacted by external forces, thereby causing failure of the vehicle's braking system.

[0004] Therefore, we proposed a brake air chamber with a reinforced structure to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a brake air chamber with a reinforced structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The structurally reinforced brake air chamber includes an air chamber warehouse, a cover plate is fixedly connected to the front end of the air chamber warehouse, a base is provided in the air chamber warehouse, a support plate is fixedly connected to the front end of the base, a support rod is fixedly connected to the upper end of the support plate, two limit rods are fixedly connected to the front end of the base and are symmetrically arranged above and below the support rod, the support rod passes through the cover plate and is slidably connected thereto, the two limit rods both pass through the cover plate and are slidably connected thereto, a first protective sleeve is fixedly connected to the front end of the cover plate, a second protective sleeve is fixedly connected to the front end of the cover plate and is symmetrically arranged above and below the first protective sleeve, the support rod passes through the first protective sleeve and is slidably connected thereto, and the two limit rods pass through the corresponding second protective sleeves and are slidably connected thereto.

[0008] Preferably, reinforcing ribs are fixedly connected between the first protective sleeve and the two second protective sleeves.

[0009] Preferably, a diaphragm is fixedly connected to the inner wall of the cylindrical surface of the air chamber, and the rear end of the base is in close contact with the diaphragm.

[0010] Preferably, two air pressure pipes correspondingly arranged up and down are fixedly connected on the outer wall of the cylindrical surface of the air chamber warehouse.

[0011] Preferably, a spring is fixedly connected to the upper end of the support plate, and one end of the spring away from the support plate is fixedly connected to the cover plate.

[0012] Preferably, the support rod and the front ends of the two limit rods are fixedly connected to a connecting block, and a connecting hole is provided on the connecting block.

[0013] Compared with the existing technology, the advantages of this device are:

[0014] 1. Two limit rods are set to limit the support rod 5 to a fixed movement axis to prevent it from becoming unstable after too many movements and thus deviating from the set movement axis, affecting the braking effect. At the same time, the two limit rods also share the pressure on the support rod 5 to prevent the support rod 5 from being broken due to excessive pressure.

[0015] 2. The first protective sleeve 10 and the second protective sleeve 11 are used to protect the limit rod and the support rod to prevent them from being damaged by external forces. At the same time, reinforcing ribs are arranged between the protective sleeves to make the structure more stable and not easily deformed.

[0016] To sum up, the utility model has a stable structure and can limit the support rod to prevent it from moving too much and causing unstable connection, thereby deviating from the set movement axis. The support rod and the limit rod are protected by the protective sleeve to prevent them from breakage and damage, and they will not be easily deformed, so the utility model is highly practical.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 The structure of the brake air chamber with enhanced structure includes an air chamber compartment 1, and two air pressure pipes 9 are fixedly connected on the outer wall of the cylindrical surface of the air chamber compartment 1 and arranged correspondingly up and down. A diaphragm 8 is fixedly connected to the inner wall of the cylindrical surface of the air chamber compartment 1, and a base 3 is arranged in the air chamber compartment 1, and the rear end of the base 3 is in contact with the diaphragm 8. A support plate 4 is fixedly connected to the front end of the base 3, and a support rod 5 is fixedly connected to the upper end of the support plate 4. A spring 6 is fixedly connected to the upper end of the support plate 4, and the spring 6 is sleeved on the support rod 5. A cover plate 2 is fixedly connected to the front end of the air chamber compartment 1, and the end of the spring 6 away from the support plate 4 is fixedly connected to the cover plate 2. In the initial state, the base 3 pushes the diaphragm 8 backward to a state of being recessed backward due to the elasticity of the spring 6, and the diaphragm 8 divides the inside of the air chamber compartment 1 into two spaces. When the air pressure pipe 9 transports gas to the space behind the diaphragm 8, the diaphragm 8 is bulged by air pressure, and the base 3 is pushed forward. The diaphragm 8 is made of rubber and has good flexibility and resilience.

[0023] The front end of the base 3 is fixedly connected with two limit rods 7 symmetrically arranged above and below the support rod 5. The support rod 5 passes through the cover plate 2 and is slidably connected thereto. The two limit rods 7 pass through the cover plate 2 and are slidably connected thereto. The front end of the cover plate 2 is fixedly connected with a first protective sleeve 10. The front end of the cover plate 2 is fixedly connected with a second protective sleeve 11 symmetrically arranged above and below the first protective sleeve 10. The support rod 5 passes through the first protective sleeve 10 and is slidably connected thereto. The two limit rods 7 pass through the corresponding second protective sleeve 11 and are slidably connected thereto. The support rod 5 is limited on the set motion axis by the two limit rods 7. When the diaphragm 8 bulges and pushes the base 3 forward, the support plate 4 squeezes the spring 6 toward the cover plate 2. The support rod 5 on the support plate 4 and the two limit rods 7 on the base 3 slide forward along the first protective sleeve 10 and the second protective sleeve 11. When the air pressure behind the diaphragm 8 is released through the air pressure pipe 9, the base 3 moves backward due to the elastic return of the spring 6, thereby driving the support rod 5 and the limit rod 7 to slide backward along the first protective sleeve 10 and the second protective sleeve 11. The base 3 moves backward due to the elastic return of the spring 6 and pushes the diaphragm 8 to the initial state of being recessed backward.

[0024] The first protective sleeve 10 and the two second protective sleeves 11 are fixedly connected with reinforcing ribs 12. The first protective sleeve 10 and the second protective sleeve 11 protect the support rod 5 and the limit rod 7 from being damaged by external forces. At the same time, the reinforcing ribs 12 make the structure more stable and prevent the support rod 5 and the limit rod 7 from being deformed or broken due to excessive pressure. The front ends of the support rod 5 and the two limit rods 7 are fixedly connected with a connecting block 13, and a connecting hole 14 is provided on the connecting block 13. The connecting block 13 can be connected to the cam in the brake mechanism through the connecting hole 14 on the connecting block 13, and the connecting block 13 is driven forward or backward by the support rod 5 and the limit rod 7, so that the camshaft in the brake mechanism rotates forward or backward to achieve the braking action. The brake mechanism is a prior art in the art, and the cam, camshaft and other mechanisms therein can be easily known by those skilled in the art, and no further explanation is given here.

[0025] When using the utility model, gas is delivered to the internal space of the air chamber 1 behind the diaphragm 8 through the air pressure pipe 9, and the diaphragm 8 is bulged by the air pressure, pushing the base 3 and the support plate 4 forward, thereby driving the support rod 5 and the limit rod 7 to slide forward along the first protective sleeve 10 and the second protective sleeve 11. After the air pressure in the internal space of the air chamber 1 behind the diaphragm 8 is released, the base 3 moves backward due to the elastic reset of the spring 6, pushing the diaphragm 8 backward to a concave state, and the support rod 5 and the limit rod 7 slide backward along the first protective sleeve 10 and the second protective sleeve 11. When the support rod 5 and the limit rod 7 slide forward or backward, they drive the connecting block 13 to slide forward or backward together, so that the connecting block 13 drives the camshaft in the brake mechanism to rotate forward or backward through the connecting hole 14 to achieve braking movement. The brake mechanism is a prior art in the art, and the cam, camshaft and other mechanisms therein can be easily known by those skilled in the art, and no further explanation is given here.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
