Abstract
The utility model relates to a hydraulic and pneumatic shock absorber, which comprises a plunger supporting bar, an air cavity, a sleeve barrel, an oil cylinder, a clip spring and an oil seal. The bottom of the inner cavity of the oil cylinder is provided with a truncated-cone-shaped bumper post, and a step and a clip spring hole are arranged in the inner cavity at the upper part of the oil cylinder, wherein, the clamp spring is clip spring is installed in the clip spring hole. The plunger supporting bar is provided with the air cavity, one end of the plunger supporting bar which corresponds to the inner cavity of the oil cylinder is provided with a pillar body, one to four oil holes are symmetrically arranged at the back part of the pillar body, and a lateral surface of the other end of the plunger supporting bar is provided with a valve hole which is communicated with an air cylinder. After motor oil is placed in the oil cylinder, the plunger supporting bar is sheathed in the oil cylinder. After the oil cylinder is sheathed with the sleeve barrel, the oil seal is positioned in the oil cylinder; then, the oil cylinder is tightly clamped by the clamp spring, a dust cover is sheathed in the oil cylinder, and air is filled in through an air valve according to requirements. The utility model is the hydraulic and pneumatic shock absorber, which has the advantages of simple structure, good performance of shock absorption, wearing property and low cost. The utility model is suitable for solar cars, electric motor cars, compact cars, tricycles, etc.
Description
The utility model belongs to bumper, particularly a kind of hydraulic-pneumatic bumper.
The bumper structure of existing motor bike, three-wheel vehicle, battery-driven car etc. all is to be screwed spring.Make complexity is installed, the cost height can't be regulated.
The purpose of this utility model be to provide a kind of simple in structure, damping performance good, durable, hydraulic-pneumatic bumper that cost is low.
Technical solution of the present utility model is such, comprise by the piston strut bar, air cavity, sleeve, oil cylinder, jump ring, oil sealing, the cylinder cavity bottom is by platform taper bumpar post, oil cylinder top inner chamber has step and clamp spring hole, clamp spring hole is installed jump ring, the piston strut bar has air cavity, the corresponding cylinder cavity of one end has the important actor body, symmetry has 1～4 oilhole behind the important actor body, and a side of the other end has the porthole hole and is communicated with air cavity, and oil cylinder is inserted in the piston strut bar after putting into machine oil, put into oil sealing after being inserted in sleeve, tighten oil sealing with jump ring then, be inserted in cover of dust, as required from the air valve injecting gas.
The utility model has the advantages that simple in structure, damping performance good, durable, cost is low.Be applicable to solar automobile, battery-driven car, miniature car, three-wheel vehicle etc.
Below in conjunction with drawings and Examples to the utility model further instruction.
Accompanying drawing is an integral installation structure cutaway view of the present utility model.
In the accompanying drawing, porthole hole and oil hole (1), air cavity (2), piston strut bar (3), cover of dust (4), jump ring (5), oil sealing (5), sleeve (7), oilhole (8), oil cylinder (9), machine oil (10), bumpar post (11), fixed orifice (12), important actor body (13).
Most preferred embodiment of the present utility model is such.Shown in accompanying drawing, the bumper of original spring structure, change the bumper of hydraulic-pneumatic structure into, mounting structure is fairly simple like this, cost-cutting.Specifically be by platform taper bumpar post (11) at oil cylinder (9) intracavity bottom, oil cylinder (9) top inner chamber has step and clamp spring hole, clamp spring hole is installed jump ring (5), piston strut bar (3) has air cavity (2), the corresponding cylinder cavity of one end of bar (3) has important actor body (13), important actor body (13) back symmetry has 1～4 oilhole (8), plays pressure-reducing cushioning, prevents the effect of clashing into.One side of the other end has porthole hole (1) and is communicated with air cavity (2), oil cylinder (9) is inserted in piston strut bar (3) after putting into machine oil (10), puts into oil sealing (6) after being inserted in sleeve (7), uses jump ring (5) chucking oil sealing then, be inserted in cover of dust (4), get final product from the air valve injecting gas as required.
