Description

Technical Field

[0001] This utility model relates to the field of high-speed rail dust cover technology, and in particular to a high-strength dust cover for high-speed rail shock absorbers. Background Technology

[0002] The dust cover for high-speed rail shock absorbers is a detachable dustproof device used for shock absorbers in high-speed trains. Its main function is to reduce dust entering the inside of the shock absorber when the piston rod extends or retracts, thus playing an important role in the operation of the shock absorber. The dust cover also protects the lubricating oil inside the shock absorber from leaking out and prevents the shock absorber from being covered by dust, ensuring that the shock absorber can maintain its optimal working condition.

[0003] Existing dust covers for high-speed rail shock absorbers have poor strength in their annular section during actual use. They are prone to deformation when exposed to the external environment for a long time, which affects the dustproof effect. In addition, the structural stability of the bottom of the dust cover is not good, which can easily cause the dust cover to detach from the shock absorber. A high-strength dust cover for high-speed rail shock absorbers is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A high-strength dust cover for a high-speed rail shock absorber includes a dust cover body composed of an annular segment 1, an upper conical segment 2, and an annular seat 3. The annular segment 1, the upper conical segment 2, and the annular seat 3 are integrally formed. A reinforcing component is provided through the end of the annular segment 1 away from the center. The reinforcing component includes several circular holes 6 located at the lower end of the annular seat 3. Reinforcing ribs 7 are provided through each of the several circular holes 6. The several reinforcing ribs 7 are vertically provided through the end of the annular segment 1 away from the center and abut against and press against its top surface. Fixing bolts 8 are threaded into each of the several circular holes 6. The several fixing bolts 8 abut against and press against the lower ends of the several reinforcing ribs 7 respectively. The reinforcing ribs 7 are arranged in a ring at equal intervals. The reinforcing ribs 7 are made of aluminum alloy. Several reinforcing ribs 7 are inserted into several circular holes 6 at the lower end of the annular seat 3, and the reinforcing ribs 7 are arranged to pass through the end of the annular segment 1 away from the center until the upper ends of the reinforcing ribs 7 are pressed against the top surface of the annular segment 1. Several fixing bolts 8 are screwed into several circular holes 6 and pressed against the reinforcing ribs 7, which effectively positions the reinforcing ribs 7 in the annular segment 1 and the circular holes 6. Thus, the aluminum alloy reinforcing ribs 7 can improve the strength of the annular segment 1 of the dust cover body and prevent the annular segment 1 from deforming and affecting the dustproof effect.

[0023] The annular seat 3 has annular protrusions 4 on its annular sidewalls near both the upper and lower ends. The inner annular wall of the annular segment 1 is coated with a wear-resistant layer 5. The wear-resistant layer 5, made of silica, improves the wear resistance of the annular segment 1 and extends the service life of the dust cover. The annular protrusions 4 and the annular seat 3 are integrally formed. The wear-resistant layer 5 is made of silica. A buffer assembly is provided between the opposing sidewalls of the two annular protrusions 4. The buffer assembly includes an annular opening 9 located at the lower end of the lower annular protrusion 4. An annular sealing block 10 is inserted into the annular opening 9. Adhesive is filled between the annular sidewall of the annular sealing block 10 and the annular inner wall of the annular opening 9. Several fixing rods 11 are fixedly connected to the upper end of the annular sealing block 10. The upper ends of the fixing rods 11 vertically penetrate the top surface of the annular opening 9 and are bonded and fixed to the lower end of the upper annular protrusion 4. Several buffer springs 12 are fixedly connected between the opposite sidewalls of the annular protrusion 4. Several buffer springs 12 are respectively sleeved on several fixed rods 11. The fixed rods 11 are arranged in a ring at equal intervals. The material of the annular sealing block 10 is wear-resistant rubber. The lower end of the annular sealing block 10 is on the same horizontal plane as the lower end of the annular seat 3. The annular sealing block 10 is inserted into the annular opening 9 and the fixed rods 11 are arranged to pass through the lower annular protrusion 4. Several buffer springs 12 are respectively sleeved on the fixed rods 11, and the upper ends of the fixed rods 11 are pressed against the upper annular protrusion 4. Adhesive is squeezed between the annular sealing block 10 and the annular opening 9, so that the fixed rods 11 cooperate with the buffer springs 12 to improve the counterweight and structural stability of the dust cover body and prevent the dust cover body from easily detaching from the shock absorber.

[0024] In use, this invention involves inserting several reinforcing ribs 7 into several circular holes 6 at the lower end of the annular seat 3, ensuring that the reinforcing ribs 7 penetrate the annular segment 1 away from the center, until the upper ends of the reinforcing ribs 7 are pressed against the top surface of the annular segment 1. Several fixing bolts 8 are then screwed into the circular holes 6 and pressed against the reinforcing ribs 7, effectively positioning the reinforcing ribs 7 within the annular segment 1 and the circular holes 6. This allows the aluminum alloy reinforcing ribs 7 to improve the strength of the annular segment 1 of the dust cover body, providing protection against dust. To prevent the annular segment 1 from deforming and affecting the dustproof effect, an annular sealing block 10 is inserted into the annular opening 9, and several fixing rods 11 are set through the lower annular protrusion 4. Several buffer springs 12 are respectively sleeved on several fixing rods 11, and the upper ends of several fixing rods 11 are pressed against the upper annular protrusion 4. Adhesive is squeezed between the annular sealing block 10 and the annular opening 9, so that several fixing rods 11, together with buffer springs 12, improve the counterweight and structural stability of the dust cover body, and prevent the dust cover body from easily detaching from the shock absorber.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
