However, the above structure has low strength, affecting its use. Utility Model Content

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a brake chamber support assembly structure and axle that uses a mounting plate connected to an axle housing fixing plate via a connecting hole at its support end to counteract the torque on the chamber support assembly.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] The brake chamber support assembly structure includes a shaft tube, a seat plate, and a mounting plate located inside the seat plate;

[0006] The base plate has through holes extending through it from both inside and outside, and the through holes cooperate with the shaft tube;

[0007] The mounting plate has a supporting end and a connecting end opposite to the supporting end. The inner side of the supporting end is provided with an inwardly extending supporting plate. The supporting plate has two fixing holes for installing the air chamber. The connecting end has a mounting hole, an adjustment hole, and a connecting hole that penetrate through it internally and externally. The mounting hole mates with the shaft tube. The adjustment hole extends circumferentially along the shaft tube. The connecting hole is away from the supporting plate relative to the adjustment hole. The mounting plate is connected to the fixing plate of the axle housing through the connecting hole.

[0008] Furthermore, the connecting end has a first plate edge, which is located on the same side of the mounting plate as the support plate and integrally protrudes along the radial direction of the shaft tube to form a connecting plate. The connecting plate is provided with the adjustment hole and the connecting hole.

[0009] Furthermore, the connecting plate has a second edge away from the first edge, the second edge being arc-shaped, and the connecting plate being perpendicular to the first edge, with its area gradually increasing from the first edge to the second edge.

[0010] Furthermore, the connecting hole extends radially along the shaft tube and is provided with bolts for connecting the fixing plate.

[0011] Furthermore, a screw is fitted inside the adjustment hole, and the inner end of the screw passes inward through the adjustment hole and is connected to the connecting arm of the brake adjustment arm.

[0012] Furthermore, it includes a reinforcing plate having a first end and a second end near the fixing hole relative to the first end. The first end is fixedly connected to the outer peripheral wall of the shaft tube, and the second end is fixedly connected to the outer plate surface of the mounting plate. The reinforcing plate, the shaft tube, and the mounting plate form a space. When viewed in a direction perpendicular to the outer plate surface, the projection of the second end is located between the projections of the two fixing holes.

[0013] Furthermore, the support plate is integrally bent inward from the support end to form a support plate. The support plate is perpendicular to the mounting plate and has two connecting lugs. A clearance space is formed between the two connecting lugs for the telescopic rod of the air chamber to pass through. Each connecting lug has a fixing hole that penetrates both of its surfaces. The air chamber is engaged with the fixing hole by bolts.

[0014] Furthermore, each of the two outer peripheral walls of the shaft tube is recessed in the circumferential direction to form a stepped portion. The stepped portion penetrates the end face of the shaft tube along the axial direction. The through hole and the mounting hole respectively cooperate with the outer peripheral walls of the two stepped portions and abut against the two end faces of the two stepped portions that are close to each other.

[0015] The brake chamber bracket assembly structure of this utility model features a connecting hole at the support end of the mounting plate, allowing the mounting plate to connect to the fixing plate of the axle housing. This integrates the positioning plate into the support end of the mounting plate, thereby counteracting the torsional force on the mounting plate and ensuring stable thrust output from the air chamber, thus improving structural strength. This brake chamber bracket assembly structure is simple, lightweight, and low-cost.

[0016] This utility model embodiment also provides an axle, including the brake chamber bracket assembly structure described in any of the above embodiments. Attached Figure Description

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 3 As shown, this utility model embodiment provides a brake chamber bracket assembly structure, which is applied to the axle brake of a heavy vehicle, including a shaft tube 1, a seat plate 2, a mounting plate 3 located inside the seat plate 2, and a reinforcing plate 4.

[0022] The shaft tube 1 is sleeved on the camshaft 300. The outer peripheral walls at both ends of the shaft tube 1 are respectively recessed to form a stepped portion 11 along its circumference. The stepped portion 11 penetrates the end face of the shaft tube 1 along its axial direction. The seat plate 2 is fixed to the brake base plate (not shown) of the brake by bolts. A through hole 21 is opened in the middle of the plate, which is connected to the outer end of the shaft tube 1.

[0023] Mounting plate 3 has a support end 31 and a connecting end 32 opposite to the support end 31. The inner side of the support end 31 is provided with an inwardly extending support plate 311. The support plate 311 has two fixing holes 3111 for mounting the air chamber 200. Specifically, the support plate 311 is integrally bent and extended inward from the support end 31. The support plate 311 is perpendicular to the mounting plate 3 and has two connecting lugs 3112. A clearance space 3113 is formed between the two connecting lugs 3112 for the telescopic rod of the air chamber 200 to pass through. Each connecting lug 3112 has a fixing hole 3111 that penetrates its two surfaces. The air chamber 200 is installed by bolts engaging with the fixing holes 3111.

[0024] The connecting end 32 has a mounting hole 321, an adjustment hole 322, and a connecting hole 323 that pass through it internally and externally. The mounting hole 321 mates with the shaft tube 1. Specifically, the through hole 21 and the mounting hole 321 mate with the outer peripheral walls of the two stepped portions 11 and abut against the two end faces of the two stepped portions 11 that are close to each other for axial limiting. The adjustment hole 322 extends circumferentially along the shaft tube 1 and is arc-shaped. It is used to adjust the clearance of the brake adjusting arm 100. The connecting hole 323 is away from the support plate 311 relative to the adjustment hole 322. The mounting plate 3 is connected to the fixing plate of the axle housing through the connecting hole 323. That is, the positioning plate is integrated into the support end 31 of the mounting plate 3, which can counteract the torque on the mounting plate 3, so that the thrust of the air chamber 200 is stably output, reducing brake noise and improving structural strength. It also has the characteristics of simple structure, light weight, and low cost.

[0025] To further simplify the structure and improve its strength, specifically, the connecting end 32 has a first plate edge 324, which is located on the same side of the mounting plate 3 as the support plate 311 and integrally protrudes radially along the shaft tube 1 to form a connecting plate 320. The connecting plate 320 has the adjustment hole 322 and the connecting hole 323. More specifically, the connecting plate 320 has a second plate edge 3201 away from the first plate edge 324. The second plate edge 3201 is arc-shaped, and the connecting plate 320 is perpendicular to the first plate edge 324, with its area gradually increasing from the first plate edge 324 to the second plate edge 3201.

[0026] In this embodiment, the connecting hole 323 extends radially along the shaft tube 1 to form a strip-shaped hole, which facilitates the adjustment of the installation position of the mounting plate 3. The connecting hole 323 is provided with bolts for connecting the fixing plate. When the bolts are loosened, the bolts can move within the connecting hole 323 to adjust their position. In order to facilitate the design and adjust the gap of the adjusting arm 100, a screw 325 is fitted in the adjusting hole 322. The inner end of the screw 325 passes inward through the adjusting hole 322 and is connected to the connecting arm 101 of the brake adjusting arm 100. When the screw 325 is loosened, the screw 325 can move within the adjusting hole 322 to realize the gap adjustment of the adjusting arm 100.

[0027] The reinforcing plate 4 has a first end 41 and a second end 42 that is close to the fixing hole 3111 relative to the first end 41. The first end 41 is fixedly connected to the outer peripheral wall of the shaft tube 1 by welding, and the second end 42 is fixedly connected to the outer plate surface 30 of the mounting plate 3 by welding. The reinforcing plate 4, the shaft tube 1 and the mounting plate 3 form a space 5. When viewed in a direction perpendicular to the outer plate surface 30, the projection of the second end 42 is located between the projections of the two fixing holes 3111. That is, the reinforcing plate 4 is located at the stress point of the mounting plate 3, so as to further improve the structural strength.

[0028] The brake chamber bracket assembly structure of this utility model features a connecting hole at the support end of the mounting plate, allowing the mounting plate to connect to the fixing plate of the axle housing. This integrates the positioning plate into the support end of the mounting plate, thereby counteracting the torsional force on the mounting plate and ensuring stable thrust output from the air chamber, thus improving structural strength. This brake chamber bracket assembly structure is simple, lightweight, and low-cost.

[0029] This utility model embodiment also provides an axle (not shown), including the brake chamber bracket assembly structure described in any of the above embodiments.
