Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loader drive axle assemblies, and particularly relates to a loader drive axle housing. Background Art
[0002] As an important component part of a loader swing drive axle, the design of the loader drive axle housing directly affects the use comfort and quality of the loader swing drive axle. The existing loader frames are generally installed on the frame mounting seats at the two axle tubes of the axle housing. In actual use, since the fuselage and the axle housing need to be on the same horizontal plane, when encountering a harsh working environment, the loader fuselage tilts severely, and even causes rollover, affecting the operation safety. To solve this problem, a swing axle has emerged. It adopts a structure in which the frame is installed on a swing frame, the swing frame is installed on a swing shaft, and the swing shaft is installed on the axle housing of the axle housing. When the tires on the left and right sides of the drive axle of the loader are not at the same height, the fuselage can still be kept horizontal, improving the driving comfort and safety. However, this swing axle has the following defects: First, the main reduction mounting flange of the used axle housing is large, and the axle housing is large, resulting in a large internal space of the axle housing, and too much lubricating oil needs to be added to the inner cavity of the axle housing, affecting the passability; Second, the overall weight of the axle housing is heavy, and the fuel economy is poor. Summary of the Invention
[0003] The purpose of the utility model is to solve the above defects and provide a loader drive axle housing with simple and compact structure, low manufacturing and maintenance costs, long service life, high driving comfort and safety.
[0004] To achieve the above purpose, a loader drive axle housing of the utility model includes axle heads 1, axle tubes 2 on both sides of the axle housing, a main reduction mounting flange 3, and an axle housing 8. Four bracket limiting stops 4 are evenly arranged in the axle housing 8; swing limiting blocks 7 are arranged at the upper ends of the axle tubes 2 on both sides; four bracket yielding notches 5 are arranged on the main reduction mounting flange 3, two on each of the left and right sides of the main reduction mounting flange 3; a circular disc tooth yielding groove 12 is arranged on the inner side of the axle housing 8; a weight reduction groove 11 is arranged at the center of the rear swing frame mounting seat 10 outside the axle housing 8, and a reinforcing rib 9 is arranged at each of the upper and lower ends of the connection between the rear swing frame mounting seat 10 and the axle housing 8; a "field" - shaped heat dissipation rib 6 is arranged on the front side of each of the axle tubes 2 on both sides.
[0005] The loader drive axle housing with the above structure optimizes the relevant structures. While meeting the use requirements, it also has good economy and has the following technical features and beneficial effects:
[0006] 1. Swing limiting blocks 7 are arranged at the upper ends of the axle tubes 2 on both sides, so that the drive axle no longer tilts after tilting to a certain degree, avoiding interference between the tires and the fuselage and ensuring safety.
[0007] 2. There are four bracket clearance notches 5 on the main reduction installation flange 3, two on each of the left and right sides of the main reduction installation flange 3, for the clearance of the brackets during the installation of the main reducer assembly, making the axle housing smaller and reducing the internal space of the axle housing, ensuring the compactness and passability of the drive axle.
[0008] 3. There is a circular disc gear clearance groove 12 on the inner side of the axle housing 8, which can provide clearance for the disc gear (i.e., the passive spiral bevel gear), ensuring the compactness of the drive axle. At the same time, the disc gear clearance groove 12 also has the effect of weight reduction. While meeting the performance requirements, it reduces the weight of the axle housing, makes the axle housing smaller and reduces the internal space of the axle housing, ensuring the compactness and passability of the drive axle and improving economy.
[0009] 4. There is a weight reduction groove 11 at the center of the rear swing frame mounting seat 10, which can reduce the weight of the axle housing and at the same time reduce the machining area of the rear swing frame mounting seat 10, improving the machining efficiency.
[0010] 5. One reinforcing rib 9 is provided at each of the upper and lower ends of the connection between the rear swing frame mounting seat 10 and the axle housing 8, which can ensure the strength of the rear swing frame mounting seat 10 and prevent cracking at the connection with the axle housing 8 during operation.
[0011] 6. One "field" - shaped heat - dissipation rib 6 is provided on the front side of each of the two axle tubes 2 on both sides, which can improve the heat - dissipation effect of the axle housing.
[0012] 7. This structure is simple and compact, with low manufacturing cost, reliable quality and long service life. Description of the Drawings

Detailed Embodiment
[0017] The following further details the detailed embodiment of the axle housing of a loader drive axle of the present utility model with reference to the drawings.
[0018] Figure 1-Figure 3As shown in the figure, a bridge housing of a loader drive axle of the present utility model includes axle heads 1, axle tubes 2 on both sides of the bridge housing, a main reduction gear mounting flange 3, and a bridge housing 8. Four bracket limiting stop openings 4 are evenly arranged in the bridge housing 8; swing limiting blocks 7 are arranged at the upper ends of the two axle tubes 2 on both sides; four bracket让位 notches 5 are arranged on the main reduction gear mounting flange 3, two on each of the left and right sides of the main reduction gear mounting flange 3; a circular disc tooth让位 groove 12 is arranged on the inner side of the bridge housing 8; a weight reduction groove 11 is arranged at the center of the rear swing frame mounting seat 10 located outside the bridge housing 8, and a reinforcing rib 9 is arranged at each of the upper and lower ends of the connection between the rear swing frame mounting seat 10 and the bridge housing 8; a "field" - shaped heat dissipation rib 6 is arranged on the front side of each of the two axle tubes 2 on both sides. It should be noted that the term "让位" is a bit unclear in the original Chinese. I've translated it as "让位" for now, but it might need to be adjusted according to the specific meaning in the context of the patent. If it has a more specific technical term, that should be used for a more accurate translation.
