Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model is for existing problem, provide a kind of shock absorber structure and automobile, object need be set in the structure of shock absorber body periphery to solve existing helical spring, adds the weight of cost of production and suspension system, and produce the problem of larger installation interference.
As Figure 1-Figure 2, embodiment of the present utility model provides a kind of shock absorber structure, comprising: work sleeve 1, is set in the oil storage cylinder barrel 2 outside work sleeve 1, be fed through the piston rod 3 of one end of work sleeve 1, piston 4 that be connected with piston rod 3, that be positioned at work sleeve 1 inside; Wherein, piston 4 moves along with the to-and-fro motion of piston rod 3.
The cylindrical shell of work sleeve 1, oil storage cylinder barrel 2 is equipped with folding structure 5; Preferably, the material of folding structure 5 is spring steel, and folding structure 5 possesses helical spring function, and the kinetic transformation that can be effectively beated by vehicle body is elastic potential energy and is absorbed by folding structure 5.
Piston 4 is fixedly connected with piston rod 3; In work sleeve 1, the part of piston more than 4 is upper chamber 6, and the part of piston less than 4 is lower chambers 7;
Piston 4 is provided with the rebound valve 8 can opened towards lower chambers 7 and the flowing valve 9 can opened towards upper chamber 6;
The recuperation valve 11 being provided with the compression valve 10 can opened towards oil storage cylinder barrel 2 at the bottom of the cylinder of work sleeve 1 and can opening towards lower chambers 7;
Wherein, the compression process of this shock absorber structure is: the wheel of vehicle moves upward (when such as wheel rolls protruding to ground), and wheel is near suspension, and shock absorber structure is compressed, first folding structure 5 is compressed, and the kinetic transformation of being beated by vehicle body is elastic potential energy; Piston 4 moves down thereupon, causes the volume of lower chambers 7 to reduce, and oil pressure raises, and fluid flows to upper chamber 6 through flowing valve 9; Because upper chamber 6 to be accounted for a part of volume by piston rod 3, therefore the volume increased in upper chamber 6 is less than the volume that lower chambers 7 reduces, therefore some fluid pushes compression valve 10 open, flow back to oil storage cylinder barrel 2, these valves just create the damping force of paired suspension compresses motion to the throttling action of fluid.
Wherein, the extension process of this shock absorber structure is: the wheel of vehicle moves downward (when such as wheel is absorbed in ground pit), and wheel is away from suspension, and shock absorber structure is stretched, first folding structure 5 is stretched, and the kinetic transformation of being beated by vehicle body is elastic potential energy; Piston 4 moves up thereupon, causes the volume of upper chamber 6 to reduce, and oil pressure raises, and flowing valve 9 is closed, and the fluid of upper chamber 6 inside is pushed rebound valve 8 open and flowed into lower chambers 7; Because upper chamber 6 to be accounted for a part of volume by piston rod 3, therefore the volume reduced in upper chamber 6 is less than the volume that lower chambers 7 increases, therefore a part of vacuum is produced in lower chambers 7, now, fluid in oil storage cylinder barrel 2 is just pushed recuperation valve 11 open and is flowed into lower chambers 7 and supplement, and these valves just create the damping force of paired suspension stretching exercise to the throttling action of fluid.
Preferably, oil storage cylinder barrel 2 top is provided with the oil sealing 12 for closed oil storage cylinder barrel 2 cylindrical shell, avoids the fluid of oil storage cylinder barrel 2 inside to flow out.
Preferably, oil sealing 12 top is provided with dust cover structure 13.
