The utility model provides a traditional buffer block beat the in-process from top to bottom at the shock absorber, receive spring tray extrusion deformation easily and produce the abnormal sound, influence the problem of driving the travelling comfort.
Description
Technical Field
The utility model relates to the technical field of auto-parts, especially, relate to a buffer block of band corrugation form dust cover.
Background
The shock absorber of the automobile is connected with the chassis and the automobile body, and provides proper damping quantity for the relative movement of the chassis and the automobile body to absorb the swinging of the automobile body caused by the rebounding force of the elastic element, so that the automobile body is more stable. The upper and lower mounting point of shock absorber is installed respectively on automobile body and chassis, and the buffer block dust cover shape of traditional motorcycle type is straight tube type, and at the shock absorber in-process of beating from top to bottom, the straight section of thick bamboo of dust cover receives spring tray extrusion deformation easily and produces the abnormal sound, influences the driving comfort. Therefore, a novel buffer block with the corrugated dustproof cover at the forehead is required to be invented.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a take buffer block of corrugate dust cover solves traditional buffer block and beats the in-process from top to bottom at the shock absorber, receives spring tray extrusion deformation easily and produces the abnormal sound, influences the problem of driving comfort.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a take buffer block of corrugate dust cover, includes buffer portion, lower dust cover that top-down set gradually, the inside of buffer portion, lower dust cover communicates with each other, the cover body of lower dust cover is the corrugate structure.
Further, a ring groove is formed in the outer peripheral surface of the buffer portion.
Furthermore, a plurality of groups of buffer grooves are arranged on the inner wall of the bottom of the buffer part.
Furthermore, the buffer grooves are uniformly distributed at intervals along the inner wall of the bottom of the buffer part.
Further, the buffer grooves are provided with at least three groups and are arranged on the inner wall of the buffer part along the circumferential direction.
Further, a straight-tube-shaped upper dust cover is arranged between the buffer part and the lower dust cover.
Furthermore, the buffer part, the upper dust cover and the lower dust cover are integrally formed.
Further, the wall thickness of the buffer part is larger than that of the upper dust cover and the lower dust cover.
The utility model has the advantages that: the corrugated dustproof cover of the buffer block can effectively prevent abnormal sound caused by extrusion deformation of the spring tray; a plurality of dashpots of buffering portion bottom design can reduce the buffer block and just receive the rigidity when extrudeing, promotes and strikes soft degree to promote whole car travelling comfort.
The present invention will be described in more detail with reference to the accompanying drawings and examples.
Drawings
Fig. 1 is a diagram of a buffer block with a corrugated dust cover according to the present invention.
Figure 2 is a bottom view of the utility model discloses a buffer block of band corrugation dust cover.
Fig. 3 is a cross-sectional view of the buffer block with the corrugated dust cover of the present invention.
Detailed Description
The buffer block with the corrugated dustproof cover as shown in fig. 1 to 3 comprises a buffer part 1 and a lower dustproof cover 3 which are sequentially arranged from top to bottom, wherein the buffer part 1 is communicated with the lower dustproof cover 3, and the cover body of the lower dustproof cover 3 is of a corrugated structure.
Preferably, in combination with the above solution, in order to ensure that the bumper block has good vibration damping, buffering and energy absorbing properties, the outer circumferential surface of the buffering portion 1 is provided with a ring groove 11.
Preferably, combine above-mentioned scheme, in order to reduce the buffer block and just receive the rigidity when extrudeing, promote and strike soft degree to promote whole car travelling comfort, the bottom inner wall of buffer portion 1 is provided with a plurality of groups of dashpot 12.
Preferably, in combination with the above solution, in order to ensure uniform stress, the buffer grooves 12 are uniformly distributed at intervals along the bottom inner wall of the buffer part 1.
Preferably, in combination with the above solution, the buffer grooves 12 are provided with at least three groups and are circumferentially arranged on the inner wall of the buffer part 1. The specific distribution quantity and size of the buffer grooves are set according to the initial rigidity requirement of the buffer blocks.
Preferably, in combination with the above-mentioned solution, in order to save production cost when the length design requirement of the dust cover is satisfied, a straight-tube-shaped upper dust cover 2 is further provided between the cushioning portion 1 and the lower dust cover 3.
Preferably, in combination with the above scheme, in order to facilitate processing and save production cost, the buffer part 1, the upper dust cover 2 and the lower dust cover 3 are integrally formed.
Preferably, in combination with the above-described aspect, in order to increase the elastic modulus of the cushioning portion 1 and improve the shock absorption effect, the thickness of the cushioning portion 1 is larger than the thicknesses of the upper dust cover 2 and the lower dust cover 3.
During design, the size of an inner hole of the buffer part is slightly smaller than that of the piston rod, and the buffer part and the piston rod are in interference fit after assembly; the length of the dust cover needs to be larger than the length of the piston rod exposed when the shock absorber is pressed downwards to the limit; the lower buffer grooves 12 of the buffer part are distributed equally, and the specific distribution quantity and size are set according to the initial rigidity requirement of the buffer block.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited to the above embodiments, and various modifications made by the method and the technical solution of the present invention or applications without modification are all within the protection scope of the present invention.
