Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1 to 5, an oil seal protection structure 100 for a shock absorber of an automobile according to an embodiment of the present invention includes a body 101.
The body 101 is a cylindrical cylinder with an open end, a central through hole 102 for penetrating the piston rod of the shock absorber is formed in the closed end 1011 (the end opposite to the open end) of the body 101, and four fan-shaped bosses 103 are arranged on the end face of the closed end 1011 of the body 101. Four fan-shaped bosses 103 are evenly distributed on the peripheral side of the central through hole 102, the four fan-shaped bosses 103 are located inside the body 101, and a groove 106 is formed between every two adjacent fan-shaped bosses 103.
Preferably, a square groove is formed between two adjacent sector-shaped bosses 103. The four fan-shaped structures are equal in size and are uniformly distributed on the circular upper end face, and the transition area of each fan-shaped structure is a square groove.
The four fan-shaped bosses 103 are arranged to increase the supporting rigidity of the circular upper end face of the shock absorber oil seal protection structure, so that when the compression buffer block 500 impacts the circular upper end face of the shock absorber oil seal protection structure, the circular upper end face (the closed end of the body 101) of the shock absorber oil seal protection structure has enough supporting rigidity, meanwhile, the protruding part of the upper end face of the shock absorber oil seal 300 can be avoided, and the shock absorber oil seal protection structure is prevented from interfering with the upper end face of the shock absorber oil seal.
The inner wall of the body 101 is provided with a plurality of ribs 104 along the axial direction, and the plurality of ribs 104 are uniformly distributed along the circumferential direction. Preferably, the number of ribs 104 is eight.
In this embodiment, the body 101, the sector boss 103, the rib 104, and the flange 105 are integrally formed by injection molding. The oil seal protection structure 100 of the automobile shock absorber adopts an integrated injection molding mode, so that the strength of the oil seal protection structure of the shock absorber of the off-road vehicle is improved, and the production efficiency is also improved.
Preferably, the oil seal protection structure of the automobile shock absorber is made of a PP material. The Chinese name of the PP material is polypropylene, and the foreign language name of the PP material is polypropylene, which is called PP for short. Cross country vehicle shock absorber oil blanket protection architecture, its whole PP material that is, through injection molding technology one shot forming, lightweight degree is high.
The periphery of the open end of the body 101 is also provided with an outward flange 105. Preferably, the outer edge 1051 of the cuff 105 is wedge-shaped.
In a preferred embodiment, the rib 104 is a rectangular prism, and a wedge 1041 is disposed at one end of the rib 104 near the flange 105.
The provision of the ribs 104 provides structural reinforcement to the overall shock absorber oil seal protection structure. The eight rectangular edges are in interference fit with the outer wall of the outer oil storage cylinder 400 of the shock absorber, so that the whole oil seal protection structure of the shock absorber is fixed on the outer oil storage cylinder 400 of the shock absorber.
Under the support of the seal of the outer oil storage cylinder of the shock absorber, the upper end face of the oil seal of the shock absorber can be protected from being damaged by the compression buffer block 500 during compression deformation. And shock absorber oil blanket protection architecture also provides good working face for compression buffer block 500's impact deformation, avoids compression buffer block 500's abnormal damage. The lower end of the edge is provided with the wedge-shaped structure, so that the convenience of assembling the oil seal protection structure of the shock absorber onto the outer oil storage cylinder 400 of the shock absorber can be ensured.
In this embodiment, the body 101 may be a cylindrical thin-walled tubular structure with a circular upper end surface (closed end) to provide a good working surface for impact deformation of the compression bumper. The center of the circular upper end surface is provided with a cylindrical through hole (central through hole) for allowing the shock absorber connecting rod 200 to pass through, and the diameter of the cylindrical through hole is slightly larger than the outer diameter of the shock absorber connecting rod 200, so that the compression damping block 500 is prevented from entering into a gap between the compression damping block 500 and being damaged in advance when being compressed and deformed. The flanging has the function of clamping the closing-in part of the shock absorber protective cover 600, and the outer edge 1051 of the flanging 105 is in a wedge shape, so that the convenience of assembling the shock absorber protective cover 600 can be ensured.
The oil seal protection structure of the cross-country vehicle shock absorber of each embodiment has the advantages of simple structure, good strength, light weight and low cost, can effectively protect the oil seal of the shock absorber from being damaged by the compression buffer block, and also provides a supporting structure for fixing the lower port of the shock absorber protective cover 600, so that the service life of the shock absorber is greatly prolonged, and meanwhile, the service life of the compression buffer block is also greatly prolonged.
According to another embodiment of the invention, an automobile is provided, which comprises the oil seal protection structure of the automobile shock absorber according to any one of the above technical solutions. Because the automobile is prior art except the oil seal protection structure of the shock absorber of the cross country vehicle, the repeated description is omitted here. The automobile adopts the oil seal protection structure of the automobile shock absorber, so the same beneficial technical effects are obtained.
It should be noted that the features of the above embodiments and examples may be combined with each other without conflict.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
