A new axle half shaft clutch separation structure

Abstract

This utility model relates to the field of automotive technology, and in particular to a novel axle half-shaft clutch separation structure, including a flange. The flange has a mounting groove at its bottom, and a connecting shaft is disposed inside the mounting groove. The bottom end of the connecting shaft is fixedly connected to the axle. A convex ring is fixedly connected to the top of the flange. A milled groove is formed on the top of the convex ring, and a mating groove is formed on the top of the milled groove. The interior of the mating groove communicates with the interior of the mounting groove. A bushing is disposed on the top of the convex ring, and two symmetrical assembly blocks are fixedly connected to the bottom of the bushing. The surfaces of the assembly blocks are slidably connected to the interior of the milled groove. This novel axle half-shaft clutch separation structure, through the switching of two modes of the device and the force of the spring on the bushing, can make the assembly blocks more stably positioned inside the milled groove, thereby forming a whole from the flange, bushing, and mating ring. This allows the vehicle's own power to more stably drive the tires to rotate, enabling the vehicle to move more smoothly.

Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a novel axle half-shaft clutch separation structure. Background Technology

[0002] The half-shaft, also called the drive shaft, is the shaft that connects the differential to the drive wheels. The half-shaft is the shaft that transmits torque between the gearbox reducer and the drive wheels. There is a universal joint at each of its inner and outer ends, which are connected to the reducer gear and the inner ring of the wheel hub bearing through the splines on the universal joints. When the car is in use, the half-shaft will drive the belt to rotate.

[0003] Upon investigation, it was found that some existing vehicle bodies have wheel hubs directly mounted on the axle half-shafts, allowing the vehicle body to directly drive the tires to rotate. However, when the vehicle body requires external power to move, the connection between the axle and the differential and other structures results in a large force required to move the vehicle body. This leads to a decrease in the ease of vehicle movement. To address this issue, technological innovations will be implemented based on existing devices. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of axle half-shaft clutch separation structure.

[0005] This utility model is achieved through the following technical solution: a novel axle half-shaft clutch separation structure, including a flange, a mounting groove at the bottom of the flange, a connecting shaft inside the mounting groove, an axle fixedly connected to the bottom end of the connecting shaft, a convex ring fixedly connected to the top of the flange, a milled groove at the top of the convex ring, a mating groove at the top of the milled groove, the interior of the mating groove communicating with the interior of the mounting groove, a bushing at the top of the convex ring, two symmetrical assembly blocks fixedly connected to the bottom of the bushing, the surface of the assembly blocks slidingly connected to the interior of the milled groove, a movable groove inside the bushing, the movable groove having a T-shaped cross-section, a mounting plate slidingly connected inside the movable groove, a fixing bolt threaded inside the mounting plate, and a separation stabilizing device inside the mating groove.

[0006] Furthermore, the separation and stabilization device includes a mating disc, the surface of which is slidably connected to the interior of a mating groove, an extension ring fixedly connected to the interior of the mating disc, a first positioning groove extending to the outside of the mating disc being formed on the surface of the extension ring, the interior of the first positioning groove communicating with the interior of a milled groove, the surface of an assembly block being slidably connected to the interior of the first positioning groove, a second positioning groove being formed on the top of the mating disc, a protrusion being provided on the bottom of the assembly block, and the surface of the protrusion on the assembly block being slidably connected to the interior of the second positioning groove.

[0007] Furthermore, the extension ring has a first stabilizing groove inside, and the top end of the connecting shaft slides through the mounting groove, the mating groove and the interior of the extension ring in sequence and extends into the interior of the movable groove.

[0008] Furthermore, the surface of the fixing bolt is connected to the internal thread of the connecting shaft.

[0009] Furthermore, a spring is provided inside the movable groove, and the spring is located at the bottom of the mounting plate.

[0010] Furthermore, a second stabilizing groove is provided on the outer surface of the connecting shaft. The interior of the second stabilizing groove is connected to the interior of the first stabilizing groove. A pin is slidably connected inside the first stabilizing groove, and the surface of the pin is slidably connected to the interior of the second stabilizing groove.

[0011] Furthermore, a first protective ring is fixedly connected to the top of the flange, a convex ring is disposed inside the first protective ring, a power groove is opened on the top of the first protective ring, a second protective ring is disposed inside the power groove, and the interior of the second protective ring is fixedly connected to the outer surface of the bushing.

[0012] Furthermore, both the second protective ring and the first protective ring have a fixedly connected marking block on their outer surfaces.

[0013] The beneficial effects of this utility model are as follows: 1. This novel axle half-shaft clutch separation structure, through the switching of two modes of the device, and the force of the spring on the bushing, can make the assembly block more stably located inside the milled groove, thereby making the flange, bushing and mating plate form a whole, so that the vehicle body's own power can more stably drive the tire to rotate, and the vehicle body can move more smoothly. Through the force of the spring on the bushing, the protrusion set on the assembly block is fixed inside the second positioning groove, so that the assembly block is released from the fixing of the protruding ring, and the bushing and mating plate form a whole. Thus, when the external power unit drives the vehicle body to move, the tire can spin freely on the connecting shaft through the flange, so that the external force can drive the vehicle body to move more smoothly, and thus make it easier for the operator to use the device.

[0014] 2. The new type of axle half-shaft clutch separation structure can protect the convex ring and bushing through the first and second protective rings. This reduces the possibility of impurities in the external environment entering the device during the separation of the bushing and convex ring, which could cause the device to jam. This allows the device to operate more smoothly. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Example 1 like Figures 1-5As shown, a novel axle half-shaft clutch separation structure includes a flange 1. A mounting groove 20 is formed at the bottom of the flange 1, and a connecting shaft 3 is disposed inside the mounting groove 20. The bottom end of the connecting shaft 3 is fixedly connected to the axle 2. The flange 1 is mounted on the wheel hub of the external vehicle body. A convex ring 4 is fixedly connected to the top of the flange 1. A milled groove 5 is formed at the top of the convex ring 4, and a mating groove 18 is formed at the top of the milled groove 5. The interior of the mating groove 18 communicates with the interior of the mounting groove 20. A bushing 6 is provided at the top of the convex ring 4, and two symmetrical assembly blocks 7 are fixedly connected to the bottom of the bushing 6. The surface of the assembly blocks 7 is slidably connected to the interior of the milled groove 5. A movable groove 19 is formed inside the bushing 6. The movable groove 19 has a T-shaped cross-section, and a mounting plate 8 is slidably connected inside the movable groove 19. A fixing bolt 9 is threadedly connected inside the mounting plate 8. A separation stabilizing device is provided inside the mating groove 18. Specifically, the separation and stabilization device includes a mating disc 11, the surface of which is slidably connected to the interior of a mating groove 18. The top of the mating disc 11 is higher than the top of the convex ring 4. An extension ring 12 is fixedly connected inside the mating disc 11. A first positioning groove 13 extending to the outside of the mating disc 11 is formed on the surface of the extension ring 12. The interior of the first positioning groove 13 communicates with the interior of the milled groove 5. The surface of the assembly block 7 is slidably connected to the interior of the first positioning groove 13. By sliding the assembly block 7 into the interior of the first positioning groove 13 and the milled groove 5, the mating disc 11 and the flange 1 can rotate synchronously. A second positioning groove 15 is formed on the top of the mating disc 11. The interior of the second positioning groove 15... The lower surface is slightly higher than the top of the convex ring 4. The bottom of the assembly block 7 is provided with a protrusion. The surface of the protrusion on the assembly block 7 is slidably connected to the inside of the second positioning groove 15. After the protrusion on the assembly block 7 rotates into the inside of the second positioning groove 15, the wheel hub can more smoothly drive the flange 1 to rotate independently and make the bushing 6 firmly on the axle 2. This realizes the axle half-shaft clutch, realizing two modes: the tire rotating independently and the axle 2 driving the tire to rotate synchronously. When the vehicle body is towed by external power, the separation of the device enables the tire to drive the flange 1 to rotate independently, so that the external power can more smoothly drive the vehicle body to move. The extension ring 12 has a first stabilizing groove 14 inside. The top end of the connecting shaft 3 slides through the mounting groove 20, the mating groove 18 and the interior of the extension ring 12 in sequence and extends into the interior of the movable groove 19. The surface of the fixing bolt 9 is connected to the internal thread of the connecting shaft 3, and the mounting plate 8 is fixed to the connecting shaft 3 by the fixing bolt 9. A spring 10 is installed inside the movable groove 19. The spring 10 is located at the bottom of the mounting plate 8. The mounting plate 8 can position the spring 10 and allow the spring 10 to exert force on the bushing 6. The outer surface of the connecting shaft 3 is provided with a second stabilizing groove 17. The interior of the second stabilizing groove 17 is connected to the interior of the first stabilizing groove 14. A pin block 16 is slidably connected inside the first stabilizing groove 14. The surface of the pin block 16 is slidably connected to the interior of the second stabilizing groove 17. Through the pin block 16, the first stabilizing groove 14 and the second stabilizing groove 17, the mating disc 11 and the connecting shaft 3 can be formed as a whole, and the connecting shaft 3 can drive the mating disc 11 to rotate. When the protrusion provided on the assembly block 7 slides into the interior of the second positioning groove 15, the mating disc 11 can drive the bushing 6 to rotate. A first protective ring 21 is fixedly connected to the top of the flange 1. A convex ring 4 is disposed inside the first protective ring 21. A power groove 23 is provided on the top of the first protective ring 21. A second protective ring 22 is disposed inside the power groove 23. The interior of the second protective ring 22 is fixedly connected to the outer surface of the bushing 6. The first protective ring 21 and the second protective ring 22 can protect the convex ring 4 and the bushing 6, and reduce the entry of impurities in the external environment into the device when the bushing 6 and the convex ring 4 separate, which could cause the device to jam. This allows the device to operate more smoothly. Both the outer surfaces of the second protective ring 22 and the first protective ring 21 are fixedly connected with marking blocks 24. The marking blocks 24 enable workers to more clearly understand that the protrusions on the assembly block 7 are inside the milling groove 5 or the second positioning groove 15, and make it easier for workers to use the device. This embodiment provides a novel axle half-shaft clutch separation structure. In use, after the operator first installs the flange 1 on the wheel hub, when the vehicle body needs its own power to move, the assembly block 7 is located inside the milled groove 5. At the same time, the force of the spring 10 on the bushing 6 makes the assembly block 7 more stable inside the milled groove 5, so that the flange 1, bushing 6 and mating plate 11 form a whole, so that the vehicle body's own power can more stably drive the tire to rotate, and the vehicle body can move more smoothly. When the vehicle body needs external power to move, the worker pulls the bushing 6 to make the assembly block 7 disengage from the milling groove 5 and rotate. When the protrusion on the assembly block 7 rotates into the second positioning groove 15, the spring 10 exerts force on the bushing 6 to make the protrusion on the assembly block 7 securely inside the second positioning groove 15, thereby releasing the assembly block 7 from the protruding ring 4 and making the bushing 6 and the mating plate 11 form a whole. Thus, when the external power device drives the vehicle body to move, the tires can rotate freely on the connecting shaft 3 through the flange 1, so that the external force can drive the vehicle body to move more smoothly, and the worker can use the device more conveniently. The first protective ring 21 and the second protective ring 22 can protect the convex ring 4 and the bushing 6, and reduce the possibility of impurities in the external environment entering the device when the bushing 6 and the convex ring 4 separate, which could cause the device to jam. This allows the device to operate more smoothly.
