Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to an improved hydraulic shock absorber for locomotives and vehicles. Background Technology

[0002] As is well known, absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the vehicle.

[0003] When driving over uneven surfaces, although the shock-absorbing spring can filter out the vibrations from the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping.

[0004] However, if the main body of a common shock absorber is damaged, the entire unit needs to be replaced, and the disassembly process is quite complicated. This leads to increased maintenance costs and reduced work efficiency for staff. Therefore, it is necessary to solve this technical problem. Utility Model Content

[0019] 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 protection scope of the present utility model.

[0020] Please see Figure 1-3 The present invention provides a technical solution: the improved locomotive and rolling stock hydraulic shock absorber includes a shock absorber 1, both the upper and lower ends of the shock absorber 1 are provided with detachable connecting rods 2, both of the two connecting rods 2 are provided with connecting components for connecting the shock absorber 1, and a bearing 3 is fixed at the end of the connecting rod 2.

[0021] The connecting assembly includes a mounting cavity on the connecting rod 2, which communicates with the outside. A sleeve 4 is fixed to the inner wall of the mounting cavity. A first insertion rod 5 is provided inside the sleeve 4. The two ends of the first insertion rod 5 pass through the side wall of the sleeve 4. A spring 6 is provided on the outer wall of the first insertion rod 5. A baffle is fixed on the first insertion rod 5. The left and right ends of the spring 6 abut against the baffle and the inner wall of the sleeve 4, respectively. A connecting plate 7 exposed to the outside is provided at the end of the first insertion rod 5. A handle 8 is fixed on the connecting plate 7. A connecting frame 9 is fixed inside the mounting cavity. A second insertion rod 11 is provided at both ends of the shock absorber 1, located inside the mounting cavity. A fixing bolt 10 is provided on the connecting frame 9, and the fixing bolt 10 passes through the second insertion rod 11. 1. The mounting cavity sidewall has a fitting groove for the second plug rod 11 corresponding to the two positions of the first plug rod 5, and the first plug rod 5 cooperates with the fitting groove. When the shock absorber 1 needs to be disassembled and replaced as a whole, the handle 8 is pulled out to remove the first plug rod 5 from the inner cavity of the second plug rod 11. Then the fixing bolt 10 is rotated off to achieve quick disassembly. During installation, the second plug rod 11 is inserted into the mounting cavity, and then the end of the fixing bolt 10 is fixed to the connecting frame 9. During the insertion process, the spring 6 resets the first plug rod 5. Compared with the traditional shock absorber structure, this structure can directly replace the shock absorber 1 when it is damaged, and the replacement time is lower, improving the practicality of the shock absorber 1.

[0022] In daily use, the second plug rod 11 is prone to shaking in the mounting cavity. In this utility model, a limiting block 12 is fixed at the top of the mounting cavity, and a connecting groove is provided on the second plug rod 11 at the position corresponding to the limiting block 12. Through the limiting block 12, the limiting block 12 can reduce the shaking of the second plug rod 11 in the mounting cavity and improve the overall practicality.

[0023] In daily use, if the end of the first plug rod 5 is rectangular, it is easy for the first plug rod 5 to get stuck if it is not aligned with the inner groove during insertion. In this utility model, the end of the first plug rod 5 is semi-circular to facilitate insertion. As described above, when the first plug rod 5 is inserted into the inner groove, the first plug rod 5 and the inner groove make contact and get stuck at the right angle. The semi-circular shape allows the first plug rod 5 to enter the inner groove, reducing the chance of getting stuck and improving the practicality of the first plug rod 5.

[0024] In summary, this improved locomotive hydraulic shock absorber allows for quick disassembly when the entire shock absorber 1 needs to be disassembled and replaced. Simply pull the handle 8 to remove the first connector 5 from the inner cavity of the second connector 11, and then rotate the fixing bolt 10 to remove it. During installation, the second connector 11 is inserted into the mounting cavity, and the end of the fixing bolt 10 is then fixed to the connecting bracket 9. During the insertion process, the spring 6 returns the first connector 5 to its original position. Compared to traditional shock absorber structures, this structure offers several advantages. When the shock absorber 1 is damaged, it can be directly replaced, and the replacement time is relatively short, improving the practicality of the shock absorber 1. Through the aforementioned limiting block 12, the limiting block 12 can reduce the shaking of the second plug rod 11 inside the mounting cavity, improving the overall practicality. Through the above, when the first plug rod 5 is inserted into the inner groove, the first plug rod 5 contacts and is stuck at the right angle with the inner groove. The semi-circular shape allows the first plug rod 5 to enter the inner groove, reducing the possibility of jamming and improving the practicality of the first plug rod 5.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
