Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular, to a 130 through axle for trucks with a part-time driving function. Background Art

[0002] Agricultural trucks are deeply favored by rural users for their strong climbing ability, large load capacity, low consumption, and low cost, and are widely used in rural areas. An agricultural truck mainly consists of a frame, a carriage mounted on the frame, and a power device and a power transmission device mounted on the frame. The engine as the power device and the clutch and gearbox as the power transmission devices are generally located at the front of the carriage. The engine crankshaft is arranged longitudinally along the agricultural tricycle, and the power output therefrom passes through the clutch, gearbox, drive shaft to the differential, and then drives the left and right rear wheels of the agricultural tricycle through the left and right half shafts.

[0003] Currently, as a transportation tool, when an agricultural truck is traveling on mountainous or rough roads, due to terrain limitations, the driving wheels of the agricultural truck are prone to suspension and loss of grip, resulting in the vehicle being unable to move. At this time, external force is required to move the agricultural truck. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a 130 through axle for trucks with a part-time driving function.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A 130 through axle for trucks with a part-time driving function, comprising a front axle, a middle axle, a rear axle, and a driver. The front axle is connected to an output end of the driver, the middle axle is connected to the other output end of the driver, and the rear axle is connected to the middle axle.

[0006] The middle bridge consists of a protective shell, a cover plate, a connecting shaft, a first gear, a clamping ring, a driving shaft, a second gear and a differential body assembly. One end of the protective shell is open. The connecting shaft is rotatably installed in the protective shell. A first bearing is installed at the contact position between the connecting shaft and the protective shell. The first gear is installed on the connecting shaft. An arc-shaped block one is installed on the first gear. A plurality of arc-shaped blocks one are equidistantly installed and arranged in a circle. A plurality of clamping grooves are provided on the connecting shaft. The clamping ring is slidably installed on the connecting shaft and is snap-connected with the clamping grooves. An arc-shaped block two is provided on the clamping ring. A plurality of arc-shaped blocks two are equidistantly installed and arranged in a circle. The arc-shaped block one is adapted to the arc-shaped block two. One end of the clamping ring is in a frustum shape. A second bearing is installed at a position on the clamping ring close to the frustum. A pneumatic valve is provided on the protective shell. A U-shaped plate is provided at the free end of the pneumatic valve. The U-shaped opening of the U-shaped plate is clamped between the second bearing and the clamping ring. The driving shaft is rotatably installed in the protective shell. The second gear is installed on the driving shaft. The second gear meshes with the first gear. A worm is installed at one end of the driving shaft. The power of the differential body (the structure of the differential body is prior art and will not be described again) is transmitted through the meshing of the worm on the driving shaft with the worm gear on the differential body.

[0007] The differential bodies on the front axle and the rear axle are the same as the described differential body. The drive of the differential body on the front axle and the drive shaft on the driver are fixedly connected through the cooperation of bolts and nuts. The drive shaft of the differential body on the rear axle and the described connecting shaft are fixedly connected through the cooperation of bolts and nuts.

[0008] The cover plate is fixedly installed at the opening of the protective shell through bolts. The connecting shaft penetrates through the cover plate and the protective shell. A third bearing is installed at the other end of the connecting shaft.

[0009] The present invention has the following beneficial effects:

[0010] By pushing the U-shaped plate to move at the free end of the pneumatic valve, the movement of the U-shaped plate drives the clamping ring to move. The movement of the clamping ring drives the arc-shaped block two to move, so that the arc-shaped block two moves to engage with the arc-shaped block one. Then it drives the first gear to rotate. The rotation of the first gear drives the second gear to rotate. The rotation of the second gear drives the driving shaft to rotate. The rotation of the driving shaft drives the worm to rotate. The rotation of the worm drives the worm gear on the differential to rotate, and then drives the output shaft of the differential (the tire is installed on the output shaft of the differential), thereby driving the tire on the middle bridge to rotate, enabling the truck to provide the force for movement when encountering rough road conditions, and avoiding pushing the truck out of the rough road by manpower or through other auxiliary devices.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figures 1 to 5 As shown, the present invention adopts the following technical solutions: A 130 through-bridge for a truck with a part-time driving function includes a front axle 1, a middle bridge 2, a rear axle 3, and a driver 4. One output end of the driver 4 is connected to the front axle 1, and the other output end of the driver 4 is connected to the middle bridge 2. The rear axle 3 is connected to the middle bridge 2.

[0020] The middle bridge 2 consists of a protective case 5, a cover plate 6, a connecting shaft 7, a first gear 8, a clamping ring 9, a drive shaft 10, a second gear 11 and a differential body 12. One end of the protective case 5 is open. The connecting shaft 7 is rotatably installed in the protective case 5. A first bearing 13 is installed at the contact position between the connecting shaft 7 and the protective case 5. The first gear 8 is installed on the connecting shaft 7. An arc-shaped block 14 is installed on the first gear 8. A plurality of arc-shaped blocks 14 are installed at equal intervals and arranged in a circular shape. A plurality of engaging grooves 15 are provided on the connecting shaft 7. The clamping ring 9 is slidably installed on the connecting shaft 7 and is engaged with the engaging grooves 15. An arc-shaped block 16 is provided on the clamping ring 9. A plurality of arc-shaped blocks 16 are installed at equal intervals and arranged in a circular shape. The arc-shaped block 14 is adapted to the arc-shaped block 16. One end of the clamping ring 9 is in a frustum shape. A second bearing 17 is installed at a position on the clamping ring 9 close to the frustum. An air-operated valve 18 is provided on the protective case 5. A U-shaped plate 19 is provided at the free end of the air-operated valve 18. The U-shaped opening of the U-shaped plate 19 is clamped between the second bearing 17 and the clamping ring 9. The drive shaft 10 is rotatably installed in the protective case 5. The second gear 11 is installed on the drive shaft 10. The second gear 11 meshes with the first gear 8. A worm 20 is installed at one end of the drive shaft 10. The drive of the differential body 12 (the structure of the differential body 12 is prior art and will not be described again) is transmitted through the meshing of the worm 20 with the worm gear on the differential body 12.

[0021] The differential bodies 12 on the front axle 1 and the differential bodies 12 on the rear axle 3 are the same as the differential body 12 described above. The drive of the differential body 12 on the front axle 1 is fixedly connected to the drive shaft 10 on the driver 4 through the cooperation of bolts and nuts. The drive shaft 10 of the differential body 12 on the rear axle 3 is fixedly connected to the connecting shaft 7 through the cooperation of bolts and nuts.

[0022] The cover plate 6 is fixedly installed at the opening of the protective case 5 through bolts. The connecting shaft 7 penetrates through the cover plate 6 and the protective case 5. A third bearing 21 is installed at the other end of the connecting shaft 7.

[0023] During specific use:

[0024] When the middle bridge 2 needs to be used, by starting the pneumatic valve, the free end of the pneumatic valve pushes the U-shaped plate to move. The movement of the U-shaped plate drives the engagement ring 9 to move. The movement of the engagement ring 9 drives the arc-shaped block two 16 to move, so that the arc-shaped block two 16 moves to the arc-shaped block one 14 for engagement, and then drives the gear one 8 to rotate. The rotation of the gear one 8 drives the gear two 11 to rotate. The rotation of the gear two 11 drives the drive shaft 10 to rotate. The rotation of the drive shaft 10 drives the worm 19 to rotate. The rotation of the worm 19 drives the worm wheel on the differential 12 to rotate, and then drives the output shaft on the differential 12 (the tire is installed on the output shaft of the differential 12), thereby driving the tire on the middle bridge 2 to rotate, so that the truck can provide the force for movement when encountering rough road conditions, avoiding pushing the truck out of the rough road by manpower or through other auxiliary devices. When operating this step, the truck needs to be stationary for operation;

[0025] When the tire at the position of the middle bridge 2 does not need to work, start the pneumatic valve in reverse to separate the arc-shaped block two 16 from the arc-shaped block one 14.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
