Description

Technical Field

[0001] This utility model relates to the field of vibration damper technology, and in particular to a dual oil circuit vibration damper. Background Technology

[0002] Shock absorbers are used to suppress the oscillations when the spring absorbs the shock and rebounds, as well as the impact from the road surface. They absorb and dissipate the vibration energy generated during vehicle operation by the flow of oil inside the shock absorber.

[0003] The connecting parts at both ends of the car shock absorber are the components that connect the car shock absorber to the car, and they are particularly important to the entire car shock absorber. At present, most car shock absorber connecting parts are molded as one piece with the car shock absorber. However, due to the frequent vibration, friction with the car hinge and the weight of the car, the car shock absorber connecting parts are often prone to wear. If it is necessary to replace the car shock absorber connecting parts, the entire car shock absorber must be replaced, which is very inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the problem mentioned in the background art above, where the connecting parts are often easily worn, and if the connecting parts of the car shock absorber need to be replaced, the entire car shock absorber needs to be replaced, which is very inconvenient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-oil-circuit shock absorber includes: a shock absorber body, a first connector, and a second connector. The upper end of the shock absorber body is connected to an oil reservoir via an oil pipe. The first connector is connected to the upper end of the shock absorber body and includes a threaded section and a connecting plate. The upper end of the shock absorber body has a threaded groove. The second connector is connected to the lower piston rod of the shock absorber body and includes a second threaded section and a lug. The lower piston rod of the shock absorber body has a second threaded groove.

[0007] Preferably, an auxiliary fixing pin is provided between the threaded section and the threaded groove.

[0008] Preferably, a circular through groove is provided on the threaded section, the axis of the circular through groove is perpendicular to the axis of the threaded section, and a fixing hole corresponding to the circular through groove is provided on the upper end of the shock absorber body.

[0009] Preferably, an auxiliary fixing pin is provided between the second threaded section and the second threaded groove.

[0010] Preferably, the second threaded section is provided with a second circular through groove, the axis of the second circular through groove is perpendicular to the axis of the second threaded section, and the upper end of the shock absorber body is provided with a second fixing hole corresponding to the second circular through groove.

[0011] Preferably, a heat sink is connected to the outside of the oil storage shell, and a baffle is installed on the oil storage shell.

[0012] Preferably, the bottom end of the baffle plate is rotatably connected to the lower end of the oil storage tank.

[0013] Preferably, the baffle plate is connected to a clamp, and the oil storage shell has a groove for installing the clamp.

[0014] Preferably, a locking pin is threaded onto the shield plate, and a locking groove corresponding to the end of the locking pin is provided on the oil storage shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model modularizes connector one, connector two, and the car shock absorber. When one of the modules is damaged, only the damaged module needs to be replaced, instead of replacing the entire module. This makes replacement convenient, reduces the owner's expenses, avoids waste of resources, and is more environmentally friendly.

[0017] By setting up heat sinks to facilitate heat dissipation of the oil reservoir, it is beneficial to the normal use of the dual oil circuit shock absorber. By setting up a baffle on the oil reservoir, the baffle can block the mud and water splashed during vehicle operation.

[0018] The baffle shell can be adjusted by using clamps and locking pins to accommodate changes in the installation position of the oil storage tank. Attached Figure Description
