Description
Technical Field
[0001] The utility model relates to the technical field of gear hobbing bushings, in particular to a shock absorber bushing with a gear hobbing structure. Background Art
[0002] For single / double-eye shock absorbers in automobiles, when installing the shock absorbers on the vehicle, relative sliding problems often occur between the upper and lower bushings of the shock absorbers, the swing arm and the vehicle body.
[0003] To this end, in the prior art, a shock absorber bushing with a hobbing structure is disclosed with a patent announcement number of CN216618373U. By arranging a plurality of hobbing teeth on both ends of the bushing, the hobbing teeth can be conveniently inserted into the counterpart when the bushing is pressed and locked with the counterpart, thereby increasing the friction between the bushing and the counterpart, and effectively preventing the bushing and the counterpart from sliding relative to each other.
[0004] Moreover, the above patent still provides a shell on the outside of the bushing to protect the bushing. However, in practice, the prior art mostly integrates the shell and the bushing by welding. When the shell is severely worn and can no longer protect the bushing, it is often necessary to connect the shell and the bushing and discard them together, which will cause serious waste of materials and increase the cost of use. Utility Model Content
[0005] In order to solve the above technical problems, a shock absorber bushing with a hobbing structure is provided, which solves the problem that most of the existing technologies use welding to integrate the shell and the bushing. When the shell is severely worn and can no longer provide good protection for the bushing, it is often necessary to discard the connected bushing together, which will cause serious waste of materials and increase the cost of use.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a shock absorber bushing with a gear hobbing structure, including a gear hobbing bushing body, and also including a protective shell arranged outside the gear hobbing bushing body;
[0007] The protective shell includes two semi-circular protective plates symmetrically clamped on the outer wall of the gear hobbing bushing body, and both sides of the two protective plates that are in contact with each other are provided with mounting slots with an L-shaped longitudinal section, and the upper and lower mounting slots form a T-shaped cavity, and a connecting component is arranged in the T-shaped cavity;
[0008] The connecting component includes a mounting block which is T-shaped and arranged in the T-shaped cavity and fixedly connected to the outer wall of the gear rolling bushing body. The mounting block has two movable grooves symmetrically arranged on one side facing the gear rolling bushing body, and an elastic clamp is arranged in the movable groove. An air injection cavity is horizontally arranged in the middle of the inner wall of the mounting block, and a ventilation cavity is also arranged in the inner wall of the mounting block. The two ends of the ventilation cavity are respectively connected to the movable groove and the air injection cavity, and a booster is arranged in the air injection cavity.
[0009] Preferably, the elastic clamp includes a connecting block slidably arranged in the opening of the movable groove, a plurality of return springs are equidistantly fixed on the inner wall of the connecting block and the innermost wall of the movable groove, and a connecting groove adapted to the connecting block is provided on the inner wall of the mounting slot.
[0010] Preferably, the booster includes a screw laterally arranged in the injection cavity and a piston threadedly connected to the outer wall of the screw, the outer wall of the piston is slidably connected to the inner wall of the injection cavity, and one end of the screw passes through the installation block and is fixed with a rotating block.
[0011] Preferably, a limit strip is transversely fixed on the inner wall of the gas injection cavity, and a notch matched with the limit strip is provided on the outer wall of the piston.
[0012] Compared with the prior art, the advantages of the utility model are:
[0013] (1) The protective shell replaces the shell structure integrated with the gear hobbing bushing body in the prior art, so that the two protective plates constituting the protective shell can be detachably connected. When the protective shell is damaged, it is only necessary to use the connecting parts to release the connection between the two protective plates, and the protective plates can be replaced separately without discarding the gear hobbing bushing body, thereby reducing the use cost and enhancing practicality.
[0014] (2) Through the setting of the T-shaped cavity, when the two protective plates are combined and connected on the gear rolling bushing body, the T-shaped cavity formed by the two sets of mounting grooves can effectively provide a holding space for the connecting parts, thereby preventing the connecting parts from being directly exposed and easily contacting foreign objects and causing wear.

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0025] Reference Figure 1 and Figure 2 As shown, a shock absorber bushing with a gear hobbing structure includes a gear hobbing bushing body 1 and a protective shell arranged outside the gear hobbing bushing body 1;
[0026] The protective shell includes two semi-circular protective plates 2 symmetrically clamped on the outer wall of the gear hobbing bushing body 1, and both sides of the two protective plates 2 that are in contact with each other are provided with mounting slots 3 with an L-shaped longitudinal section, and the upper and lower mounting slots 3 form a T-shaped cavity, and a connecting component is arranged in the T-shaped cavity;
[0027] The protective shell replaces the shell structure integrated with the gear hobbing bushing body 1 in the prior art, so that the two protective plates 2 constituting the protective shell can be detachably connected. When the protective shell is damaged, only the connection between the two protective plates 2 needs to be released by the connecting component, and the protective plates 2 can be replaced separately without discarding the gear hobbing bushing body 1, thereby reducing the use cost and enhancing the practicality.
[0028] By setting the T-cavity, when the two protection plates 2 are combined and connected on the gear rolling bushing body 1, the T-cavity formed by the two sets of mounting slots 3 can effectively provide a holding space for the connecting parts, thereby preventing the connecting parts from being directly exposed and easily contacted with foreign objects and causing wear.
[0029] Further, refer to Figure 2-7 As shown, it is worth noting that the connecting component includes a mounting block 4 which is arranged in a T-shaped shape in the T-shaped cavity and is fixedly connected to the outer wall of the gear hobbing bushing body 1. The mounting block 4 has two movable grooves 5 symmetrically arranged on one side facing the gear hobbing bushing body 1. An elastic clamp is arranged in the movable groove 5. An air injection cavity 9 is horizontally arranged in the middle of the inner wall of the mounting block 4. A ventilation cavity 10 is also arranged in the inner wall of the mounting block 4. The two ends of the ventilation cavity 10 are respectively connected to the movable groove 5 and the air injection cavity 9. A pressurizing member is arranged in the air injection cavity 9.
[0030] The elastic clamp includes a connecting block 6 slidably arranged in the opening of the movable groove 5, a plurality of return springs 8 are fixed equidistantly on the inner wall of the connecting block 6 and the innermost wall of the movable groove 5, and a connecting groove 7 adapted to the connecting block 6 is opened on the inner wall of the mounting slot 3;
[0031] By setting the connecting components, when the two protective plates 2 are symmetrically clamped on the outside of the gear hobbing bushing body 1 to form a protective shell, it is only necessary to use the booster to allow the air inside the air injection cavity 9 to enter the movable groove 5 from the ventilation cavity 10, so that the connecting block 6 in the elastic clamp slides into the connecting groove 7 under the influence of pressure, and then the protective plate 2 can be effectively fixedly connected with the installation clamp 4, ensuring the stability of the protective plate 2 on the gear hobbing bushing body 1;
[0032] During the process of the connecting block 6 sliding into the connecting groove 7, the connecting block 6 can synchronously stretch the reset spring 8 to deform, and then utilize the elastic force of the reset spring 8 so that when the booster is utilized again to reduce the internal air pressure of the movable groove 5, the connecting block 6 can be quickly reset under the elastic force of the reset spring 8 and detached from the inner side of the connecting groove 7, thereby releasing the fixed connection relationship between the protective plate 2 and the mounting block 4, and facilitating the removal of the protective plate 2.
[0033] Further, refer to Figure 6 and Figure 7 As shown, it is worth noting that the booster includes a screw 13 transversely arranged in the gas injection cavity 9 and a piston 11 threadedly connected to the outer wall of the screw 13, the outer wall of the piston 11 is slidably connected to the inner wall of the gas injection cavity 9, and one end of the screw 13 passes through the mounting block 4 and is fixed with a rotating block 14;
[0034] The knob 14 is turned to rotate the screw 13 in the gas injection chamber 9 , so that the piston 11 can slide along the screw 13 under the threaded structure, and then squeeze the gas inside the gas injection chamber 9 , so that the gas passes from the ventilation chamber 10 into the movable groove 5 .
[0035] Further, refer to Figure 7 As shown, it is worth noting that a limit strip 12 is transversely fixed on the inner wall of the gas injection cavity 9, and a notch matching the limit strip 12 is provided on the outer wall of the piston 11;
[0036] By setting the limit strip 12 and the gap, when the piston 11 slides, the limit strip 12 can remain relatively fixed and retract into the gap of the piston 11, and then the limit strip 12 cooperates with the gap to limit the movement trajectory of the piston 11 and ensure the stability of the piston 11 during movement.
[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
