[0002] The gear assembly of medium and heavy-duty trucks is the core component of the transmission system. It is mainly responsible for the transmission, speed change and torque distribution of engine power, which directly affects the vehicle's load capacity, fuel economy and reliability. It transmits the power from the drive shaft to the drive wheels after reducing speed and increasing torque. There are two common forms: single-stage reduction (such as bevel gears) and double-stage reduction (with wheel-side reducers). While existing medium and heavy-duty truck gear assemblies can meet users' needs to a certain extent, there are still some problems in actual use. For example, existing medium and heavy-duty truck gear assemblies are assembled inside the gearbox, and the gears have a lot of friction after long-term meshing and transmission, which will cause a lot of noise when the gears are in motion. Moreover, the gear assembly is located inside the gearbox, which makes it inconvenient to lubricate the gears. Utility Model Content

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1 to 3 As shown, the wear-resistant and noise-reducing gear assembly for medium and heavy-duty trucks provided by this utility model includes a gear assembly box 1, a lubrication box 2 at the upper end of the gear assembly box 1, a movable seat 10 movably installed at the upper end of the gear assembly box 1, a mounting seat 13 fixedly installed at the lower end of the movable seat 10, a nozzle 12 detachably installed inside the mounting seat 13, a connecting hose 11 installed at the lower end of the lubrication box 2, the lower end of the connecting hose 11 sleeved on the outer side of the upper end of the nozzle 12, a support frame 6 fixedly installed at the upper end of the gear assembly box 1, reciprocating screws 7 rotatably installed on both sides inside the support frame 6, the reciprocating screws 7 are interconnected by a transmission sprocket and a transmission chain, the movable seat 10 is movably sleeved on the surface of the reciprocating screws 7, and a driver 8 connected to the reciprocating screws 7 is installed on one side of the support frame 6. In this embodiment, the driver 8 is an electric driver capable of driving the reciprocating screw 7 to rotate in both directions, thereby causing the moving seat 10 to reciprocate on the reciprocating screw 7. The reciprocating movement of the moving seat 10 drives the mounting base 13 and the nozzle 12 to reciprocate and spray inside the gear assembly box 1, ensuring that the gears inside the gear assembly box 1 receive uniform lubrication. In addition, the design of the connection structure allows the nozzle 12 to be easily installed and disassembled, facilitating replacement and cleaning. The entire gear assembly structure is compact and rationally designed, which not only improves the wear resistance and noise reduction performance of the gears, but also facilitates the lubrication and maintenance of the gears.

[0017] The lubrication box 2 has an addition tube 4 on one side, and a level sensor 3 is installed inside. The level sensor 3 monitors the lubricating oil level inside the lubrication box 2 in real time. When the lubricating oil level falls below a preset value, the level sensor 3 sends a signal, reminding the operator to add lubricating oil to the lubrication box 2 through the addition tube 4 to ensure continuous lubrication of the gear assembly. This design not only improves the automation level of the equipment but also effectively avoids gear wear and malfunctions caused by insufficient lubrication, extending the service life of the equipment.

[0018] like Figure 3 and Figure 4 As shown, the wear-resistant and noise-reducing gear assembly for medium and heavy-duty trucks provided by this utility model has a connection structure between the nozzle 12 and the mounting base 13. The connection structure includes an assembly groove 14, which is opened on both sides of the mounting base 13. The assembly groove 14 is L-shaped. Assembly blocks 15 are fixedly installed on both sides of the upper end of the nozzle 12. The assembly blocks 15 are movably inserted into the interior of the assembly groove 14. Adjustment grooves are opened on both sides of the interior of the mounting base 13. A locking rod 16 passes through the interior of the adjustment groove. The upper end of the locking rod 16 extends into the interior of the assembly groove 14 and is inserted into the interior of the assembly block 15. A movable block is sleeved on the surface of the locking rod 16. A support spring 17 is sleeved on the surface of the locking rod 16. The upper end of the support spring 17 is connected to the movable block. The lower end of the locking rod 16 is movably inserted into the outer side of the mounting base 13 and is equipped with an adjustment ring 18. In this embodiment, the user pulls down the adjusting ring 18, which causes the two locking rods 16 to move downward. The locking rods 16 move the movable block, compressing the support spring 17. The upper end of the locking rod 16 is pulled out from the inside of the assembly block 15, and the locking rod 16 is fully retracted into the inside of the movable groove 19, so that the assembly block 15 can move along the assembly groove 14. The nozzle 12 can be pulled out from the inside of the mounting base 13, thereby facilitating the quick replacement of the nozzle 12.

[0019] like Figure 3 and Figure 5 As shown, the wear-resistant and noise-reducing gear assembly for medium and heavy-duty trucks provided by this utility model has an installation groove at the lower end of the gear assembly box 1. A fixing plate 5 is detachably installed inside the installation groove. A receiving box 9 is installed at the upper end of the fixing plate 5. Slots are provided on both sides of the fixing plate 5. Movable grooves 19 are provided on both sides of the installation groove. A locking strip 20 is movably installed inside the movable groove 19. One end of the locking strip 20 is movably inserted into the slot. A locking spring 21 is fixedly installed on one side of the locking strip 20. A sliding groove 22 is provided on one side of the installation groove. A slider 23 connected to the locking strip 20 is movably inserted inside the sliding groove 22. A pull strip 24 is installed at one end of the slider 23. In this embodiment, the user pulls the pull bar 24, which causes the slider 23 to slide inside the slide groove 22. The pull bar 24 causes the locking bar 20 to move inside the movable groove 19. The locking bar 20 compresses the locking spring 21, and one end of the locking bar 20 is pulled out from inside the groove. At this time, the fixing plate 5 is no longer fixed by the locking bar 20, and the fixing plate 5 can be pulled out from inside the mounting groove. The receiving box 9 at the upper end of the fixing plate 5 is also pulled out, which facilitates the cleaning of impurities inside the receiving box 9. Similarly, it also facilitates the installation of the receiving box 9.
