Description

Technical Field

[0001] The utility model relates to the field of automobile electronically controlled suspension shock absorbers, in particular to an installation and disassembly tooling structure for an external electromagnetic valve of an adjustable CDC shock absorber. Background Art

[0002] Shock absorber: A component used to suppress the vibration caused by the spring rebounding after absorbing the shock and the impact from the road surface. It is widely used in automobiles to accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness of the car.

[0003] Solenoid valves: installed on the shock absorber to control the damping.

[0004] Reservoir tube: It stores shock absorber oil and provides support.

[0005] Oil seal (OIL SEAL): Seals the oil and nitrogen at the end of the shock absorber.

[0006] like Figure 1 , 2 As shown in Figure 3, in the prior art, the end sealing of the shock absorber is achieved by spinning and curling, the oil storage cylinder A (1') is spun and rolled, and the oil seal A (2') is pressed firmly to achieve a sealing effect; the solenoid valve positioning installation is manually adjusted, the oil flow hole A (3') of the third cylinder and the solenoid valve installation cavity are rotated on the same axis, and then the solenoid valve A (5') is manually screwed into the solenoid valve installation cavity (4').

[0007] Since the electronically controlled shock absorber needs to be debugged in the early stage, the internal valve system of the shock absorber needs to be adjusted. The existing technology uses spinning and flanging to seal the end of the shock absorber. If the internal valve system needs to be adjusted, the entire shock absorber will be scrapped. In addition, it is difficult to ensure the coaxiality between the oil flow hole of the third cylinder and the installation cavity of the solenoid valve. Since the solenoid valve is manually screwed, it cannot be guaranteed to be screwed in place, and the solenoid valve is easily damaged when disassembled. Utility Model Content

[0008] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an adjustable CDC shock absorber external solenoid valve installation and disassembly tooling structure, which is convenient for the early debugging of the shock absorber, can improve the installation accuracy of the solenoid valve, improve the installation efficiency, and reduce parts loss.

[0009] The purpose of the utility model is achieved through the following technical solutions: This adjustable CDC shock absorber external solenoid valve installation and disassembly tooling structure includes:

[0010] The solenoid valve outer cylinder is arranged on the outer wall of the oil storage cylinder of the shock absorber at a position corresponding to the oil flow hole of the third cylinder. The solenoid valve is installed in the solenoid valve outer cylinder. A plurality of pits are arranged on the side of the solenoid valve away from the oil storage cylinder.

[0011] A positioning tool is used to be placed in the outer cylinder of the solenoid valve, so that the positioning protrusion arranged at the bottom of the positioning tool is inserted into the oil flow hole, and the oil flow hole and the outer cylinder of the solenoid valve are coaxially positioned; and

[0012] The loading and unloading tool has a boss matched with the pit at the bottom, and the loading and unloading tool is used to extend into the outer cylinder of the solenoid valve to tighten or loosen the solenoid valve.

[0013] As a further technical solution, a threaded sleeve is welded to the upper opening of the oil storage cylinder, which is used to cooperate with the threaded gland to tighten and seal the upper opening of the oil storage cylinder.

[0014] As a further technical solution, a gasket is arranged between the lower end surface of the threaded gland and the oil seal at the upper opening of the oil storage cylinder.

[0015] As a further technical solution, when the solenoid valve is disassembled, the location of the outer tube of the solenoid valve is used to inject shock absorber oil.

[0016] The beneficial effects of the utility model are:

[0017] 1. The threaded gland and threaded sleeve are matched to form a detachable end seal structure, which is more convenient for adjusting the internal valve system and reduces the scrapping of shock absorbers compared with the traditional spinning and flanging.

[0018] 2. A gasket is set between the lower end surface of the threaded gland and the oil seal to ensure the sealing effect of the end;

[0019] 3. The oil flow hole of the third cylinder and the installation cavity of the solenoid valve are positioned by a positioning tool (positioning protrusion), and the relative manual adjustment ensures the coaxiality and installation accuracy;

[0020] 4. The solenoid valve is installed and disassembled by loading and unloading tooling, which is more labor-saving and convenient to unscrew than manual tightening or unscrewing, and is not easy to damage the solenoid valve. At the same time, it can be guaranteed to be fully tightened after installation, effectively avoiding the situation of inadequate installation and inability to disassemble.

DETAILED DESCRIPTION

[0032] The utility model will be described in detail below with reference to the accompanying drawings:

[0033] Example: As attached Figures 4 to 10 As shown, the installation and disassembly tooling structure of the adjustable CDC shock absorber external solenoid valve includes a threaded cover 1, a gasket 2, a threaded sleeve 3, a positioning tooling 4, a solenoid valve outer cylinder 5, a third cylinder 6, a loading and unloading tooling 7, a solenoid valve 8, an oil storage cylinder 9, an oil seal 10, an oil flow hole 11, a pit 12, a boss 13 and a positioning protrusion 14.

[0034] Reference Figure 4 , 6 The solenoid valve outer cylinder 5 is arranged on the outer wall of the oil storage cylinder 9 of the shock absorber. Preferably, during assembly, the oil flow hole 11 of the third cylinder 6 needs to be rotated to a position aligned with the solenoid valve outer cylinder 5. Figure 7 , 8 As shown, the solenoid valve outer cylinder 5 is used to install the solenoid valve 8, and a plurality of circular pits 12 are provided on the side of the solenoid valve 8 away from the oil storage cylinder 9.

[0035] like Fig. 9 As shown, a positioning protrusion 14 is provided at the center of the bottom of the positioning tool 4. Before installing the solenoid valve 8, the positioning tool 4 is first placed in the outer tube 5 of the solenoid valve, as shown in FIG. Figure 6 As shown, the positioning protrusion 14 is aligned and inserted into the oil flow hole 11, so that the oil flow hole 11 and the electromagnetic valve outer tube 5 are coaxially positioned to ensure the coaxiality of the oil flow hole 11 and the electromagnetic valve outer tube 5.

[0036] like Figure 8 , 10 As shown, a cylindrical boss 13 matching the circular pit 12 is provided at the bottom of the loading and unloading tool 7. When the loading and unloading tool 7 is inserted into the solenoid valve outer tube 5, it can match the solenoid valve 8 to tighten or loosen the solenoid valve 8.

[0037] Reference Figure 4 , 5 A threaded sleeve 3 is welded on the top of the oil storage cylinder 9 to cooperate with the threaded gland 1 to tighten and seal the top of the oil storage cylinder 9. In this embodiment, welding and thread locking are used instead of crimping sealing. The threaded sleeve 3 is welded to the shock absorber oil storage cylinder 9, and the shock absorber is sealed by the threaded gland 1 and the gasket 2, and the basic length of the shock absorber is ensured to be consistent with the basic length after sealing. Preferably, the gasket 2 is arranged between the lower end surface of the threaded gland 1 and the oil seal 10 on the top of the oil storage cylinder 9.

[0038] When the solenoid valve 8 is disassembled, the location of the solenoid valve outer tube 5 is used to inject shock absorber oil.

[0039] The working process of this utility model:

[0040] Installation and positioning of the solenoid valve: Use the positioning tool 4, the outer tube 5 of the solenoid valve and the oil flow hole 11 of the third cylinder 6 for positioning, such as Figure 4 , 6 As shown, ensuring the coaxiality between the opening position of the third cylinder and the outer cylinder of the solenoid valve plays a decisive role in the accuracy of the next step of installing the solenoid valve.

[0041] Disassembly of electromagnetic valve: The cylindrical boss 13 on the electromagnetic valve assembly and disassembly tool 7 corresponds to the circular pit 12 of the electromagnetic valve 8, such as Figure 7 , 8 As shown, tighten or remove the solenoid valve 8.

[0042] During assembly, weld the threaded sleeve 3 to the shock absorber outer cylinder (oil storage cylinder 9), put the working cylinder piston rod into the shock absorber, and then rotate the oil flow hole 11 of the third cylinder 6 to a position aligned with the solenoid valve outer cylinder 5, put the positioning tool 4 into the solenoid valve outer cylinder 5, and insert the end of the positioning tool 4 (i.e., the positioning protrusion 14) into the oil flow hole 11 of the third cylinder 6 to ensure the coaxiality of the oil flow hole 11 and the solenoid valve outer cylinder 5; after completing this step, put the gasket 2 and the threaded gland 1 as shown in FIG. Figure 5 Place and tighten the threaded gland 1 and the threaded sleeve 3 to achieve the end sealing effect;

[0043] After the end threaded gland 1 is tightened, take out the positioning tool 4 and inject the shock absorber oil from the solenoid valve outer tube 5. After the oil injection is completed, use the loading and unloading tool 7 to tighten the solenoid valve 8 and the solenoid valve outer tube 5; if it is necessary to adjust the oil injection amount or replace the solenoid valve 8, the solenoid valve 8 can be taken out by using the loading and unloading tool 7.

[0044] The utility model adopts an innovative structural solution, which can facilitate the replacement of parts during the early debugging of the electric control shock absorber, is convenient for the installation and disassembly of the electromagnetic valve, improves work efficiency and reduces parts loss.

[0045] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
