Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically a front axle braking assembly. Background Technology

[0002] Due to the harsh road conditions in the mining area, the requirements for vehicle braking performance are increased. To ensure braking performance, the air pressure in the pipeline needs to be increased. As the pipeline air pressure increases, the pushing force of the air chamber increases, thereby increasing the force borne by the adjusting arm. Figure 2 As shown, the adjusting arm used in the front axle consists of a housing 41, a worm gear 42, a worm wheel 43, and an adjusting mechanism 44. The housing 41 is pushed by the air chamber 3, and the worm wheel and worm gear mechanism inside the adjusting arm 4 is locked by gears, causing the worm wheel 43 to drive the camshaft 5 to rotate. The camshaft drives the brake 7 to meet the vehicle braking requirements. However, increasing the air pressure in the pipeline will increase the thrust on the adjusting arm 4, which will lead to failures such as cracking of the housing 41 and breakage of the gears of the worm gear 42 and worm wheel 43. This will cause the adjusting arm to lose its adjusting function, affect the adjustment of the brake clearance, and lead to brake failure.

[0003] To meet usage requirements, the adjusting arm needs to be strengthened. Currently, there is no room for improvement in the materials used for the adjusting arm components, and due to installation space constraints, strengthening the adjusting arm would interfere with adjacent components. Therefore, to ensure installation clearance, the traditional adjusting arm is designed to be relatively weak while still meeting braking torque requirements. With the adjusting arm's turning radius remaining constant, when the pipeline air pressure increases, leading to increased thrust in the air chamber, the force on the meshing gears of the worm gear and worm increases, causing the worm and worm wheel gears to break. Simultaneously, the increased thrust also increases the thrust on the adjusting arm housing, causing housing cracking. During use, all of these faults will lead to the loss of the adjusting arm's adjustment function. After a period of vehicle use, the braking clearance increases. If the adjusting arm cannot adjust the braking clearance, it will lead to increased braking distance, brake failure, and other malfunctions, endangering life and property safety. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a front axle braking assembly.

[0005] The technical solution provided by the utility model is: a front axle braking assembly, comprising a steering knuckle, an air chamber bracket, an air chamber, an adjusting arm, a camshaft, a camshaft bracket, and a brake; the air chamber bracket, camshaft bracket, and brake are fixed on the steering knuckle; the air chamber bracket is provided with an air chamber; the camshaft bracket is provided with a camshaft; the adjusting arm is composed of a housing, a worm, a worm wheel, and an adjusting mechanism; the worm wheel and worm are meshed by gears, and the worm is fixed to the housing by the adjusting mechanism; the housing of the adjusting arm is connected to the air chamber, and the worm wheel of the adjusting arm is connected to the camshaft; its special feature is that the housing of the adjusting arm has an asymmetrical structure, the strength of the adjusting arm is enhanced, and the gap between the adjusting arm and the air chamber bracket remains unchanged.

[0006] Furthermore, the asymmetrical structure of the housing enhances the thickness and diameter of the housing, worm gear, and worm, increasing the contact area between the worm gear and the worm shaft.

[0007] Furthermore, the asymmetrical structure of the housing increases the center distance between the worm and the worm wheel.

[0008] The beneficial effects of this utility model are: 1. The housing of the adjusting arm adopts an asymmetrical structure, which enhances the performance of the adjusting arm without affecting the clearance between the adjusting arm and the air chamber support. 2. The housing of the adjusting arm is reinforced. While strengthening the housing, the asymmetrical structure of the housing solves the problem of interference between the adjusting arm and adjacent components after the housing is enlarged. This avoids the problem that the adjusting arm is limited by the installation space and cannot meet the requirements of increased air chamber thrust, which would cause the adjusting arm housing to break during use and affect braking performance. 3. Strengthening the worm and worm wheel increases the tooth thickness and contact area of ​​the worm and worm wheel, effectively improving the stress on the worm and worm wheel and reducing the risk of gear breakage during use. 4. Increasing the center distance between the worm and the worm wheel reduces the force on the worm gear and worm wheel, thus lowering the risk of breakage, while keeping the slewing radius of the adjusting arm constant and the thrust of the air chamber constant. 5. By strengthening the housing, worm gear, and worm wheel, the adjusting arm meets the force requirements, eliminating problems such as insufficient braking force, increased braking distance, and brake failure when the vehicle is in motion. This significantly improves the safety factor of the adjusting arm, increases the safety of vehicle use, and ensures the stable and reliable braking of the entire front axle throughout its entire life cycle.

Detailed Implementation

[0011] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.

[0012] like Figure 1 , 2 As shown, a front axle braking assembly comprises a steering knuckle 1, an air chamber bracket 2, an air chamber 3, an adjusting arm 4, a camshaft 5, a camshaft bracket 6, and a brake 7. Using the steering knuckle 1 as a base, the air chamber bracket 2, camshaft bracket 6, and brake 7 are respectively bolted to the steering knuckle 1. The air chamber 3 is mounted on the air chamber bracket 2; the camshaft 5 is mounted on the camshaft bracket 6. The adjusting arm 4 consists of a housing 41, a worm 42, a worm wheel 43, and an adjusting mechanism 44. The worm wheel 43 meshes with the worm 42 via gears, and the worm 42 is fixed to the housing 41 by the adjusting mechanism 44. The housing 41 is connected to the air chamber 3, and the worm wheel 43 is connected to the camshaft 5. To ensure that the movement of the adjusting arm 4 and the air chamber bracket 2 does not interfere, the two... The gap between the two is already at its minimum and cannot be reduced further; due to space constraints, the adjusting arm cannot be enlarged to meet the braking demand after the air pressure increases; in order to meet the braking demand, the housing 41 of the adjusting arm 4 is processed into an asymmetrical structure, which strengthens the adjusting arm 4 while ensuring that the gap between the adjusting arm 4 and the air chamber support 2 remains unchanged; the asymmetrical structure of the housing 41 strengthens the thickness and diameter of the housing 41, worm wheel 43, and worm 42, increases the contact area between the worm wheel 43 and the worm gear, and increases the strength of the housing 41, worm wheel 43, and worm gear; the center distance between the worm 42 and worm wheel 43 of the adjusting arm 4 is increased, which reduces the stress on the worm wheel 43 and worm gear while keeping the turning radius of the adjusting arm 4 and the thrust of the air chamber 3 unchanged.

[0013] This utility model discloses a front axle braking assembly. During operation, the air chamber pushes the housing of the adjusting arm to rotate, the housing drives the adjusting mechanism to rotate, the adjusting mechanism drives the worm to rotate, the worm and worm wheel are locked by gear meshing, driving the camshaft that cooperates with the worm wheel to rotate, and the camshaft drives the brake to work, thereby realizing braking.

[0014] This utility model discloses a front axle braking assembly. To improve braking performance, while maintaining the clearance between the adjusting arm and the air chamber support, the adjusting arm's housing is reinforced through an asymmetrical design. This reinforced housing improves overall housing performance, effectively solving the market-wide problem of adjusting arm housing cracking caused by increased air chamber thrust. The reinforced housing also strengthens the worm and worm wheel, increasing their meshing contact area and the force they bear, thus reducing the risk of worm and worm wheel breakage. Increasing the center distance between the worm and worm wheel further reduces the force on the worm and worm wheel gears while keeping the adjusting arm's rotation radius and air chamber thrust constant, further lowering the risk of worm and worm wheel breakage. The application of the reinforced adjusting arm effectively avoids braking failure due to adjusting arm failure, increasing vehicle safety.
