[0002] The axle of a car is connected to the chassis via the suspension, and wheels are mounted at both ends. The axle's function is to bear the load of the car and maintain its normal driving on the road. However, after a car has been used for a long time, the axle needs to be inspected. Most axles are currently fixed to the wheel hubs of the car with multiple bolts. When inspecting the axle, the wheel hubs need to be removed from the axle first. However, after long-term use, the bolts will be covered with a lot of dirt, making it difficult to quickly remove and inspect them. This makes axle inspection inconvenient, delays the normal progress of axle inspection, increases the workload of maintenance personnel, reduces the efficiency of maintenance personnel, and fails to meet actual usage needs. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides an automobile axle that is easy to maintain, which solves the problem that the existing axles are difficult to disassemble quickly, resulting in inconvenient maintenance and delaying the normal progress of axle maintenance.

[0005] The locking mechanism includes a limiting housing disposed at the end of the connecting pipe away from the axle body, and a limiting frame fixedly disposed inside the limiting housing. A limiting seat fixed to the connecting pipe is disposed inside the limiting frame. Positioning blocks are fixed at both ends on one side of the limiting seat. Positioning slots are opened on one side surface of each of the two positioning blocks. A clamping component for fixing the limiting seat is disposed on the limiting frame. The locking mechanism also includes a driving component disposed on the limiting housing for driving the clamping component to operate.

[0006] Preferably, the clamping assembly includes movable connecting plates slidably disposed at the upper and lower ends of the limiting frame, and movable locking blocks fixedly disposed on one side of the movable connecting plates, wherein the movable locking blocks match the positioning slots. Threaded rods are rotatably disposed at both ends of the limiting frame via bearings. A limiting plate fixed to the limiting housing is rotatably disposed at one end of the threaded rod via a bearing. A connecting block is threadedly connected to the threaded rod. Movable connecting rods are hinged at both ends of the connecting block, and one end of the movable connecting rod is movably hinged to the end of the movable connecting plate.

[0007] Preferably, a worm gear is fixed at the end of the threaded rod away from the limiting plate, and a worm is engaged with the limiting frame via a bearing on one side of the worm gear.

[0008] Preferably, the drive assembly includes a transmission gear ring disposed inside the limiting housing and a limiting ring groove formed on one side of the limiting housing. Both ends of the transmission gear ring are meshed with driven gears. A rotating shaft is fixed at the center of the shaft on one side of the driven gear and is rotatably connected to the limiting frame through a bearing. A transmission belt is driven and connected to the rotating shaft through a pulley, and the other end of the transmission belt is driven and connected to one end of a worm gear through a pulley.

[0009] Preferably, a connecting ring seat is fixedly provided on one side of the limiting housing, a movable dial ring is rotatably provided on the outside of the connecting ring seat, and a plurality of connecting arc blocks arranged in a circumferential array are fixedly provided on one side of the movable dial ring.

[0010] Preferably, the elastic locking element includes a plurality of fixed slots arranged in a circular array on the movable dial ring, and movable inserts disposed at both ends of the movable dial ring, wherein one end of the movable insert is movably inserted into any one of the fixed slots, and a sliding transverse groove is provided on the movable insert.

[0011] Preferably, an L-shaped sliding plate is fixedly provided inside the sliding groove, a return spring is fixedly provided on one side of the L-shaped sliding plate, a limiting block fixed to the limiting housing is fixed at the other end of the return spring, and the movable insert is slidably connected to the outside of the limiting block.

[0012] Preferably, limit bars are fixed at all four corners inside the limiting frame, and limiting slots matching the limit bars are provided at all four corners of the limiting seat.

[0013] By employing the above technical solution, the present invention provides an automotive axle that is easy to maintain, and compared with the prior art, it has at least the following beneficial effects:

[0014] 1. This invention uses a locking mechanism to fix the connecting pipe on the axle body to the car wheel hub. Through the cooperation of the drive component and the clamping component, the movable block is first pulled out from the positioning slot. Without the movable block clamping, the positioning block is pulled out from the limiting frame, thereby removing the car wheel hub from the connecting pipe. Then, the axle body can be inspected. The structure is reasonable, which makes the disassembly and inspection of the car axle more convenient, improves the work efficiency of maintenance personnel, reduces the workload of maintenance personnel, and effectively avoids the situation where the existing axle is difficult to disassemble quickly, resulting in inconvenient maintenance and delaying the normal progress of axle maintenance.

[0015] 2. This invention uses a clamping assembly to fix the positioning block to the limiting housing. The threaded rod drives the connecting block to move. The connecting block moves in both directions through the movable connecting rods at both ends. One end of the movable connecting rod pulls the movable connecting plate to move on the limiting frame. The movable connecting plate drives the movable block on one side to move out from the inside of the positioning slot on the positioning block. The movable block separates from the positioning slot, allowing the car wheel hub to be removed from the connecting pipe. This makes axle maintenance more convenient and the transmission process is stable, improving the flexibility of axle maintenance.

[0016] 3. This invention uses a drive assembly to drive the worm gear of the clamping assembly to rotate. By moving the movable ring, the movable ring drives the transmission gear ring to rotate through the connecting arc block. The transmission gear ring simultaneously drives two driven gears to rotate, and the driven gears drive the rotating shaft on one side to rotate. The rotating shaft drives the worm gear to rotate through the transmission belt, thereby driving the clamping assembly to fix the positioning block on the limiting housing. The operation is simple, which is beneficial for maintenance personnel to inspect the axle and avoids the need to spend a lot of time disassembling the axle for inspection. It is also beneficial to use. Attached Figure Description

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] Figures 1-7 An embodiment of the present invention: a convenient automobile axle includes an axle body 1 and connecting pipes 2 fixedly disposed at both ends of the axle body 1. The axle body 1 is common knowledge to those skilled in the art, and its internal structure will not be described in detail in this solution. The end of the connecting pipe 2 away from the axle body 1 is provided with a locking mechanism 3 for fixing the connecting pipe 2 to the wheel hub.

[0029] The locking mechanism 3 includes a limiting housing 31 disposed at the end of the connecting pipe 2 away from the axle body 1, and a limiting frame 32 fixedly disposed inside the limiting housing 31. A limiting seat 33 fixed to the connecting pipe 2 is disposed inside the limiting frame 32. Limiting stops 38 are fixed at each of the four corners of the inner side of the limiting frame 32. Limiting slots 39 matching the limiting stops 38 are provided at each of the four corners of the limiting seat 33. The limiting seat 33 at one end of the connecting pipe 2 is inserted into the limiting slot 39 inside the limiting housing 31. On the frame 32, four limit stops 38 are respectively inserted into the limit slots 39 at the four corners of the limit seat 33 to position the limit seat 33. Positioning blocks 34 are fixed at both ends on one side of the limit seat 33. Positioning slots 35 are opened on one side surface of each of the two positioning blocks 34. A clamping component 36 for fixing the limit seat 33 is provided on the frame 32. The locking mechanism 3 also includes a driving component 37 provided on the limit housing 31 for driving the clamping component 36 to operate.

[0030] The locking mechanism 3 is used to fix the connecting pipe 2 on the axle body 1 to the car wheel hub. Through the cooperation of the drive component 37 and the clamping component 36, the movable block 362 is first pulled out from the positioning slot 35. The positioning block 34 is not clamped by the movable block 362. Then the limiting frame 32 is pulled out from the limiting seat 33, thereby removing the car wheel hub from the connecting pipe 2. Then the axle body 1 can be inspected, which makes the disassembly and maintenance of the car axle more convenient.

[0031] Specifically, the clamping assembly 36 includes a movable connecting plate 361 slidably disposed at the upper and lower ends of the limiting frame 32, and a movable locking block 362 fixedly disposed on one side of the movable connecting plate 361. The movable locking block 362 matches the positioning slot 35. Threaded rods 363 are rotatably disposed at both ends of the limiting frame 32 via bearings. A limiting plate 364 fixed to the limiting housing 31 is rotatably disposed at one end of the threaded rod 363 via a bearing. A connecting block 365 is threadedly connected to the threaded rod 363. Movable connecting rods 366 are hinged at both ends of the connecting block 365. One end of the movable connecting rod 366 is movably hinged to the end of the movable connecting plate 361. A worm gear 367 is fixed at the end of the threaded rod 363 away from the limiting plate 364. A worm 368 is meshed and driven on one side of the worm gear 367 and is rotatably disposed with the limiting frame 32 via a bearing.

[0032] The threaded rod 363 passes through the connecting block 365 and is threadedly connected to it. When the threaded rod 363 rotates, the connecting block 365 moves linearly along the threaded rod 363. Since the two ends of the movable connecting rod 366 are movably hinged to the connecting block 365 and the movable connecting plate 361 respectively, the connecting block 365 moves towards the middle through the movable connecting rods 366 at both ends. One end of the movable connecting rod 366 pulls the movable connecting plate 361 to move on the limiting frame 32. The movable connecting plate 361 drives the movable locking block 362 on one side to move to the inside of the positioning slot 35. The movable locking block 362 clamps and fixes the positioning locking block 34 on the limiting frame 32.

[0033] Specifically, the drive assembly 37 includes a transmission gear ring 371 disposed inside the limiting housing 31, and a limiting ring groove 372 formed on one side of the limiting housing 31. The middle part of the limiting ring groove 372 is fixedly connected to the limiting frame 32 on the limiting housing 31. Driven gears 373 are meshed at both ends of the transmission gear ring 371. When the two driven gears 373 rotate, the two driven gears 373 rotate in the same direction. A rotating shaft 374 is fixed at the axis on one side of the driven gear 373 and is rotatably connected to the limiting frame 32 through a bearing. A transmission belt 375 is driven and connected to the rotating shaft 374 through a pulley, and the other end of the transmission belt 375 is driven and connected to one end of the worm gear 368 through a pulley. A connecting ring seat 376 is fixedly disposed on one side of the limiting housing 31, and the limiting housing 31 is fixed to the vehicle through the connecting ring seat 376. On the hub, the connecting tube 2 is connected to the connecting ring seat 376 via the limiting frame 32. A movable dial ring 377 is rotatably arranged on the outside of the connecting ring seat 376. Several connecting arc blocks 378 arranged in a circular array are fixedly arranged on one side of the movable dial ring 377. The connecting arc blocks 378 are rotatably connected to the limiting ring groove 372 and fixedly connected to the transmission gear ring 371. By moving the movable dial ring 377, the movable dial ring 377 drives the transmission gear ring 371 to rotate through the connecting arc blocks 378. The transmission gear ring 371 simultaneously drives two driven gears 373 to rotate. The driven gears 373 drive the rotating shaft 374 on one side to rotate. The rotating shaft 374 drives the worm gear 368 to start rotating through the transmission belt 375, thereby driving the clamping assembly 36 to operate. An elastic clip 379 is provided on the movable dial ring 377 for clamping it.

[0034] The specific implementation process is as follows: When repairing the automobile axle, the repair personnel move the movable ring 377. The movable ring 377 drives the transmission gear ring 371 on one side to rotate. The transmission gear ring 371 simultaneously drives the two driven gears 373 to rotate. The driven gears 373 drive the rotating shaft 374 on one side to rotate. The rotating shaft 374 drives the transmission belt 375 to rotate through the pulley. The transmission belt 375 drives the worm gear 368 to rotate through the pulley. The worm gear 368 drives the worm wheel 367 on one side to rotate. The worm wheel 367 drives the threaded rod 363 at its shaft center to rotate. Since the threaded rod 363 passes through the connecting block 365 and is threadedly connected to it, the rotation of the threaded rod 363 drives the connecting block 365 to move. The connecting block 365 drives the movable connecting rods 366 at both ends to move in both directions. One end of the movable connecting rod 366 pulls the movable connecting plate 361 to move on the limiting frame 32. The movable connecting plate 361 drives the movable locking block 362 on one side to move out from the inside of the positioning slot 35 on the positioning locking block 34. The movable locking block 362 separates from the positioning slot 35. At the same time, the limiting frame 32 and the connecting tube 2 loosen, so that the car wheel hub can be removed from the connecting tube 2.

[0035] Example 2

[0036] refer to Figure 5 The embodiment is basically the same as that in Embodiment 1, but with an optimization: the elastic locking member 379 includes a plurality of fixed slots 3791 arranged in a circular array on the movable dial ring 377, and movable inserts 3792 disposed at both ends of the movable dial ring 377. One end of the movable insert 3792 is movably inserted into any one of the fixed slots 3791. A sliding transverse groove 3793 is provided on the movable insert 3792. An L-shaped sliding plate 3794 is fixedly disposed inside the sliding transverse groove 3793. A return spring 3795 is fixedly disposed on one side of the L-shaped sliding plate 3794. A limiting block 3796 fixed to the limiting housing 31 is fixed at the other end of the return spring 3795. The movable insert 3792 is slidably connected to the outside of the limiting block 3796.

[0037] The specific implementation process is as follows: When it is necessary to unlock the movable ring 377, pull the movable plug 3792. The movable plug 3792 slides outside the limit block 3796. The movable plug 3792 drives the L-shaped slide plate 3794 to move. The L-shaped slide plate 3794 squeezes the return spring 3795. The return spring 3795 is compressed due to elastic deformation. The movable plug 3792 separates from the fixed slot 3791 on the movable ring 377. The movable ring 377 is no longer locked by the movable plug 3792. Then the movable ring 377 can be rotated.

[0038] During the maintenance of this vehicle axle, the maintenance personnel first pull both movable blocks 3792 simultaneously. The movable blocks 3792 slide outside the limiting block 3796, causing the L-shaped sliding plate 3794 on its inner side to move. The L-shaped sliding plate 3794 compresses the return spring 3795 on one side, causing the return spring 3795 to elastically deform and be compressed. The movable blocks 3792 separate from the fixed groove 3791 on the movable ring 377, and the movable ring 377 is no longer held in place by the movable blocks 3792. Then, the movable ring 377 is turned, causing the transmission gear ring 371 on one side to rotate. The transmission gear ring 371 simultaneously drives two driven gears 373 to rotate. The driven gears 373 drive the rotating shaft 374 on one side to rotate. The rotating shaft 374, through a leather... The pulley drives the transmission belt 375 to rotate, and the transmission belt 375 drives the worm 368 to rotate through the pulley. The worm 368 drives the worm wheel 367 on one side to rotate, and the worm wheel 367 drives the threaded rod 363 at its shaft to rotate. At the same time, the threaded rod 363 rotates and drives the connecting block 365 on it to move. The connecting block 365 drives the movable connecting rods 366 at both ends to move in both directions. One end of the movable connecting rod 366 pulls the movable connecting plate 361 to move on the limiting frame 32. The movable connecting plate 361 drives the movable locking block 362 on one side to move out from the inside of the positioning slot 35 on the positioning locking block 34. The movable locking block 362 separates from the positioning slot 35. At the same time, the limiting frame 32 and the connecting pipe 2 become loose. The car wheel hub is removed from the connecting pipe 2, and then the axle is inspected.
