further comprising: the splash guard 2 is fixedly connected to the outer side of the bottom end of the upper layer connecting frame 1, the splash guard 2 is of a horn-shaped structure with a narrow top and a wide bottom, the waterproof bottom plate 4 is fixedly installed at the upper side face of the lower layer connecting frame 3, the waterproof bottom plate 4 is in penetrating connection with the piston rod 8, the lubricating pipe 9 and the oil injection pipe 12 are arranged on the outer side of the piston rod 8 in a nested mode, the oil injection pipe 12 is fixedly connected between the upper end of the lubricating pipe 9 and the bottom side face of the upper layer connecting frame 1 through welding, and the sealing stopper 15 is connected to the outer side of the bottom end of the lubricating pipe 9 in a nested mode;

when using the device, at first when the car goes, the wheel can lead to a large amount of sewage or dust in ground to splash and fall to the damping part surface through the road surface of unevenness, install the tie point department at upper layer connecting frame 1 bottom pressure cylinder 7 this moment, receive the corruption of sewage and rust easily and cause the fracture, but shelter from through installing the protection of tubaeform fender 2 in upper layer connecting frame 1 bottom outside, can effectively block sewage and splash to pressure cylinder 7 tie point, thereby the life of damping part has been strengthened, the sewage that splashes and falls on lower floor's link 3 receives the stopping of waterproof bottom plate 4 and avoids the infiltration pollution, and waterproof bottom plate 4 can be stainless steel, thereby effectively avoid appearing because of the corrosion that sewage caused, meanwhile, piston rod 8 that reciprocates along with damping spring 6 constantly slides and inserts in pressure cylinder 7, and then lead to piston rod 8 to have one section to be in the state that exposes in the air, therefore receive the friction easily and produce wearing and tearing, but through the lubricating oil of intussuseption of lubricated pipe 9 and the oiling pipe 12 intussuseption of nestification in the piston rod 8 outside, can be followed the removal of piston rod and constantly permeate at the surface of pole, and then promote the piston rod 8 simultaneously, also form the protection rod body and the dust in order to prevent the isolation pole of the dust and prevent the dust.

When an automobile passes through a water pit and splashes sewage, a part of sewage falls on the surface of the lower-layer connecting frame 3, but the sewage is drained by blocking of the waterproof bottom plate 4 and drainage of the drainage grooves 5 formed in the two ends of the waterproof bottom plate 4, so that the retention time of the sewage on the lower-layer connecting frame 3 is very short, specifically, as shown in fig. 1 and 4, the drainage grooves 5 are also symmetrically formed in the left end and the right end of the waterproof bottom plate 4, the drainage grooves 5 vertically penetrate through the two ends of the lower-layer connecting frame 3 and the waterproof bottom plate 4, and the waterproof bottom plate 4 is connected with the lubricating pipe 9 in an inserting and combining manner, when the sewage is splashed on the upper end of the lower-layer connecting frame 3, the sewage can be prevented from permeating and corroding the inner structure of the lower-layer connecting frame 3 through the isolation of the waterproof bottom plate 4, and the sewage is drained through the drainage grooves 5 formed in the two ends of the waterproof bottom plate 4 in time, so that the time that the sewage stays on the waterproof bottom plate 4 is reduced;

when the piston rod 8 in the damper moves up and down along with the deformation of the damping spring 6, specifically, as shown in fig. 3, 4 and 5, the lubricating pipe 9 is a hollow double-layer pipe structure, the inner side wall of the lubricating pipe 9 is connected with the piston rod 8 in a fitting manner, oil inlets 10 are further circumferentially arrayed on the double-layer pipe wall at the upper end of the lubricating pipe 9, oil outlets 11 are further circumferentially arrayed on the inner layer pipe wall at the bottom end of the lubricating pipe 9, the oil filling pipe 12 is of a hollow annular sleeve structure, the oil filling pipe 12 and the lubricating pipe 9 form a communicating structure through the oil inlets 10, a thread groove 13 is further opened on the outer side surface of one end of the oil filling pipe 12, and meanwhile, the sealing piece 14 is connected with the thread groove 13 in a threaded manner, so that a maintenance person can fill lubricating oil into the hollow oil filling pipe 12 from the thread groove 13 in advance, lubricating oil can flow into the interlayer of the double-layer pipe for storage through an oil inlet 10 formed in the upper end of the lubricating pipe 9 so as to provide long-term lubrication protection for the piston rod 8, when an automobile runs, the sealing piece 14 is firmly and tightly screwed in the thread groove 13, at the moment, the piston rod 8 moves up and down in the pressure cylinder 7, the lubricating pipe 9 fixedly nested outside can be driven to slide back and forth in the central grooves of the lower layer connecting frame 3 and the waterproof bottom plate 4, along with the reciprocating sliding movement of the piston rod 8, the lubricating oil filled in the lubricating pipe 9 permeates out along the oil outlet 11 at the bottom end and is uniformly coated and covered on the exposed part surface of the piston rod 8, and further, the lubricating property of the piston rod 8 is enhanced, and the problems of corrosion and abrasion of the piston rod 8 are avoided;

when 8 when moving repeatedly of piston rod, the sealed fender piece 15 of nestification outside 8 piston rods can block the infiltration of sewage, and reduce volatilizing of lubricating oil, concretely, according to fig. 2 and fig. 4 show, sealed fender piece 15 and waterproof bottom plate 4 fixed connection, and sealed fender piece 15 is the back taper structure, and sealed fender piece 15 and lubricated pipe 9 sliding connection, the sealed piece 15 of keeping of back taper laminating closely firm laminating is at 8 outer surfaces of piston rod, and when the piston rod 8 laminating seals to keep 15 inner walls up-and-down sliding, can effectively block the infiltration of outside dust and sewage, and isolated piston rod 8 and 3 recess insides of lower floor's link volatilize of remaining lubricating oil.

The working principle is as follows: when the device is used, as shown in fig. 1-5, firstly, when an automobile runs, dust and sewage brought by wheel splash contact the surface of the shock absorption piece, the rust damage of the sewage to the connection point of the pressure cylinder 7 can be prevented through the horn-shaped fender 2 at the bottom end of the upper connecting frame 1, and the sewage falling on the lower connecting frame 3 is prevented by the waterproof bottom plate 4, and the sewage is guided and drained in time through the drainage grooves 5 arranged at the two ends in a penetrating manner, so that the surface of the shock absorption piece is kept clean, meanwhile, when the piston rod 8 runs up and down in the pressure cylinder 7 along with the shock absorption spring 6, the lubricating oil filled into the oil injection pipe 12 through the oil inlet 10 is stored in the lubricating pipe 9 embedded outside the piston rod 8, so that the lubricating pipe 9 can provide lubrication protection for the piston rod 8 for a long time, and the lubricating oil continuously permeates and leaks along the oil outlet 11 at the bottom end of the lubricating pipe 9, so as to coat the surface of the piston rod 8 moving in a wear-resistant manner, so that the shock absorption piece forms a wear-resistant protection structure, which is the working principle of the high-strength shock absorption piece for the automobile.

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