Description

Technical Field

[0001] This utility model relates to the field of mining machinery, and in particular to a self-made front axle device for trucks. Background Technology

[0002] In mining operations, mining trucks are used to transport ore, and their performance and reliability are crucial. The front axle, located at the front of the vehicle, connects the body to the front wheels and bears the weight of the front of the vehicle, ensuring proper steering and stable support for the front of the vehicle. Currently available mining truck front axles have the following problems: First, the axle joints of existing front axles are constructed from welded sheet metal. Stress analysis reveals that the welds at this location experience significant stress due to the vertical static load, longitudinal static load, and dynamic load from the vertical suspension cylinders, making them prone to cracking. Second, the brake adjusting arms used in existing front axles lack a locking mechanism, failing to prevent slippage. Third, existing front axle structures are complex, difficult to manufacture, and costly to produce. Furthermore, due to variations in operating environments and conditions, existing front axles may not meet requirements in certain special environments, resulting in limited applicability.

[0024] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0025] like Figures 1 to 4 As shown, one embodiment of this application provides a self-made front axle device for a truck, including a front axle body 20, a braking mechanism, and a steering mechanism. The front axle body 20 includes two front axle steering knuckle seats 22 welded to both ends of the front axle body 20 and a kingpin mounted on the front axle steering knuckle seats. The braking mechanism includes two brake sub-assemblies 13 respectively disposed at both ends of the front axle body 20 for achieving vehicle braking. The steering mechanism includes steering knuckles 12 disposed inside the two brake sub-assemblies 13 and a steering tie rod 21 connected to the steering knuckles 12 for coordinating vehicle steering. The front axle steering knuckle seats 22 are integrally formed structures welded to the front axle body 20. The front axle body 20 and the steering tie rod 21 are used to traction the steering knuckles 12 to rotate around the kingpin through coordinated movement, thereby controlling vehicle steering.

[0026] The self-made truck front axle device provided in this embodiment includes two parts, left and right. The two parts have the same structure and are connected by the front axle body 20 and the steering tie rod 21 to form a whole. The following structure takes the right half as an example. The whole mainly includes the brake sub-assembly 13, the steering knuckle 12, the brake chamber mechanism, and the front axle body 20.

[0027] like Figure 1 and Figure 2 As shown, the front axle body 20 has steering knuckles 12 and brake sub-assemblies 13 connected to both ends, and the front axle body 20 is connected to the brake sub-assemblies 13 through the steering knuckles 12. The brake sub-assemblies 13 are used to brake the vehicle. The front axle body 20 includes a front axle steering knuckle seat 22 and a kingpin. The kingpin is interference-fitted onto the front axle steering knuckle seat (22). The front axle steering knuckle seat 22 is welded to the side of the front axle body 20 near the steering knuckle 12, and the steering knuckle 12 is connected to the front axle body 20 through the kingpin. Furthermore, the front axle steering knuckle seat 22 is an integrally formed structure, made of ZG35CrMo casting. Welding it onto the front axle body 20 greatly reduces the stress on the front axle body 20 at this point, effectively preventing cracking failures and improving the quality stability under bending, braking, and sideslip conditions. The truck's self-made front axle assembly also includes a limiting component, which includes a limiting bolt 14 and a thrust washer 16. The limiting bolt 14 is located on the side of the steering knuckle 12 away from the brake sub-assembly 13, and is used to limit the steering angle of the steering knuckle 12 within a certain range. The thrust washer 16 is installed on the front axle steering knuckle seat 22 and the end of the steering knuckle 12 away from the brake chamber mechanism, and plays a limiting role between the front axle steering knuckle seat 22 and the steering knuckle 12. In a further embodiment, the limiting bolt 14 includes a nut and a limiting screw, which cooperate to limit the steering angle of the steering knuckle 12.

[0028] The brake chamber mechanism is mounted on the steering knuckle 12 and connected to the brake sub-assembly 13. Its braking force is transmitted from the brake chamber 8 to the brake arm 15, then to the camshaft 6, and finally to the brake sub-assembly 13. The brake chamber structure includes a front axle brake chamber 8, a chamber bracket 2, and an upper cover plate 1. The chamber bracket 2 is used to fix and support the front axle brake chamber 8, and the upper cover plate 1 is used to connect the chamber bracket 2 to the steering knuckle 12, ensuring a tight connection between the entire brake chamber mechanism and the steering knuckle 12. The brake chamber mechanism also includes an adjusting shim 5, a camshaft 6, and hexagonal head bolts 7. The adjusting shim 5 is located between the front axle steering knuckle seat 22 and the steering knuckle 12, serving as a limiting element between the steering knuckle 12 and the chamber bracket 2. The camshaft 6 is located on the side of the upper cover plate 1 away from the steering knuckle 12 and is used to connect the brake chamber mechanism to the brake sub-assembly 13. The hexagonal head bolts 7 are mounted on the chamber bracket 2, fixing the chamber bracket 2 to the upper cover plate 1.

[0029] like Figure 3As shown, the self-made truck front axle assembly also includes a thrust rod support and a suspension cylinder support 11. The thrust rod support is located at one end of the thrust rod 10 and is welded to the front axle body 20. The thrust rod 10 is connected to the front axle body 20 through the thrust rod support. The suspension cylinder support 11 includes a connecting plate 111, a reinforcing rib 112, and side plates 113. The suspension cylinder support 11 is connected to the front axle body 20 through the connecting plate 111. The upper and lower side plates 113 are arranged parallel to the front axle body 20. Preferably, there are two reinforcing ribs 112, both vertically arranged between the two side plates 113, with their ends connected to the two side plates 113 respectively. By widening the width of the connecting plate 111 and thickening the thickness of the reinforcing ribs 112, the stability and strength of the suspension cylinder support 11 are improved, and the welding strength between the suspension cylinder support 11 and the front axle body 20 is strengthened, making the structure of the self-made truck front axle assembly more stable.

[0030] like Figure 4 As shown, the braking mechanism also includes a brake arm 15 mounted on the brake sub-assembly 13. The brake arm 15 includes an adjusting rod 151, a locking element 152, and an adjusting arm 153. The adjusting arm 153 is mounted on the camshaft 6. The adjusting rod 151 is located on the side of the brake arm 15 and inserted into the brake arm 15. The locking element 152 is located at one end of the adjusting rod 15 to prevent the brake arm 15 from slipping. The locking element 152 has a structure with a locking plate, including a locking plate and a bolt. After the brake clearance is adjusted according to the assembly requirements, the locking element 152 is used to lock the brake arm 153, preventing slippage and effectively preventing the brake arm 15 from slipping.

[0031] The truck's custom-made front axle assembly also includes a grease nipple dust cap 3, a straight-through grease nipple 4, a curved-neck grease nipple 17, a trapezoidal arm 18, and a threaded seat 19. The grease nipple dust cap 3 and the straight-through grease nipple 4 are both mounted on the upper cover plate 1 and are used to lubricate components such as the steering knuckle 12. The trapezoidal arm 18 is bolted to both ends of the steering knuckle 12, and the steering tie rod 21 connects the left and right trapezoidal arms 18. The curved-neck grease nipple 17 is located at the lower end of the trapezoidal arm 18 and adds grease between the trapezoidal arm 18 and the steering knuckle 12. The threaded seat 19 is mounted on the front axle body 20 and is used to install pressure plate pins and screws, and to limit the pressure plates of other components.

[0032] In summary, the self-made truck front axle device provided by the above embodiments of this utility model includes a front axle body 20, a braking mechanism, and a steering mechanism.
