Abstract
The utility model relates to the automobile hydro-pneumatic suspension technology, in particular to a bushing mounting structure for an automobile front hydro-pneumatic suspension piston rod. The bushing mounting structure comprises a piston rod, wherein a piston head is arranged on the end surface at the front end of the piston rod, and the size of the cross section of the piston head is equal to that of the cross section of the rod body at the front end of the piston rod; and a circle of bushing is fitted on the circumferential surface at the front end of the piston rod as well as the circumferential surface of the piston head. The bushing mounting structure can reduce the thickness of the bushing, saves materials, and is simple in structure and convenient to mount.
Description
Technical field
The utility model relates to the automobile oil-gas suspension technology, is specifically related to the lining mounting structure of the preceding oleo-pneumatic suspension piston rod of automobile.
Background technique
The existing piston bar, the lining mounting structure is: piston rod front end peripheral surface has projection, the piston head that the front end end face fixedly has the cross section to equate with piston rod front end lug boss cross-sectional sizes, folder is established lining between piston head and projection.Such structure, lining need be done to such an extent that very thickly just can meet the demands, and lining is installed extremely inconvenient.
The model utility content
The technical problems to be solved in the utility model provides the preceding oleo-pneumatic suspension piston rod lining mounting structure of a kind of automobile simple in structure, easy for installation.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
Oleo-pneumatic suspension piston rod lining mounting structure before a kind of automobile, it is characterized in that, comprise piston rod, piston rod front end body of rod section radius unanimity, piston rod front end end face is provided with the piston head that the cross section equates with piston rod front end body of rod cross-sectional sizes, all is fitted with a circle lining in the peripheral surface of described piston rod front end and the peripheral surface of piston head.
The beneficial effects of the utility model: based on structure of the present utility model, because piston rod front end body of rod section radius unanimity, the cross section of piston head equates with piston rod front end body of rod cross-sectional sizes, therefore only need to cut inner chamber in the middle of the lining, be about to lining and make tubular, the peripheral surface that then lining is set in piston rod front end peripheral surface and piston head gets final product, and can reduce the thickness of lining, is convenient to again install.
Further, described piston head is connected the front end end of described piston rod by the bolt of circumferential array in its side.Piston head is fixedlyed connected with piston rod in a plurality of bolts of its side by circumferential array, connects more firmly, and the bolt circumferential array also can reduce the stress of piston rod and piston head joint to be concentrated, and increases the service life.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, oleo-pneumatic suspension piston rod lining mounting structure before the automobile, comprise piston rod 1, piston rod 1 front end end face is provided with the piston head 2 that the cross section equates with piston rod 1 front end body of rod cross-sectional sizes, piston head 2 is fixedly connected on the front end end of described piston rod 1 by the bolt 4 of circumferential array in its side, all is fitted with a circle lining 3 in the peripheral surface of described piston 1 bar front end and the peripheral surface of piston head 2.
The utility model is because piston rod front end body of rod section radius unanimity, the cross section of piston head equates with piston rod front end body of rod cross-sectional sizes, therefore only need to cut inner chamber in the middle of the lining, be about to lining and make tubular, the peripheral surface that then lining is set in piston rod front end peripheral surface and piston head gets final product, can reduce the thickness of lining, be convenient to again install.
Claims (2)
