Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the present embodiment is a kind of locomotive shock absorber, is mainly used in the secondary vibration preventing spring.
This locomotive shock absorber includes spring 1, outer tube 2, interior pipe 3 and damper bar 4, described outer tube is hollow tubular structures, described outer tube one end open is opening end 2.1, the other end is closed as closed end 2.2, the external diameter of described interior pipe will be slightly less than the internal diameter of aforementioned outer tube, pipe in above-mentioned can be located in described outer tube thus.And pipe is located in after in aforesaid outer tube in above-mentioned, and this interior pipe 3 one end is connected on the closed end of described outer tube, and the other end is extending end 3.1, extends in outside the opening end 2.1 of described outer tube.The closed end 2.2 of described outer tube is connected with damper bar 4, this damper bar is a columniform hollow body, its inside is formed with cavity, be filled with damping oil (damping oil here is also resistance oil, damping oil, high sticky lubricant oil, damping lubricant grease, high-drag lubricant oil, damping lubricant oil, shockproof oil, and it is by the wide gentle lubricating oil of high quality of high-purity inorganic thickening agent and the formulated a kind of New Damping of special artificial oil, buffering, sealing) in the cavities.
The external diameter of above-mentioned damper bar is greater than the external diameter of aforementioned outer tube 2, is formed with step surface 5 thus between described damper bar 4 and the closed end 2.1 of described outer tube.
Described outer tube 2 is arranged with aforesaid spring 1 and by described outer tube 2, above-mentioned spring 1 is carried out spacing.
The extending end 3.1 of described interior pipe is arranged with adjustment seat 6, described adjustment seat 6 is arranged with adjustment sleeve 7, and described adjustment sleeve is marked closely screw 8 by one and is removably fixed in described adjustment seat.Above-mentioned adjustment seat be can again in pipe extending end 3.1 on slide.
By the processing of the shape to above-mentioned adjustment seat and adjustment sleeve, make to form Packed space between described adjustment seat and described adjustment sleeve, and in described space, be provided with seal ring 9, the size of sealing circle will be a bit larger tham the size of sealed airspace, thus utilizes an elasticity of sealing circle 9 itself to fill full above-mentioned sealed airspace.
Described outer tube is arranged with spring 1, and described spring one end is fixed on described step surface 5, and the other end is fixed in described adjustment seat 6.
Described damper bar one end is connected with the closed end 2.2 of described outer tube, the other end is connected with conduit 4.1, and described conduit is communicated with described damper bar inside, can inject damping oil by this conduit inside damper bar, in order to prevent damping oil from leaking, be wrapped with gum cover 4.1.1 at described conduit 4.1.
Concrete, when the locomotive shock absorber of the present embodiment receives the impact force from outside, first the impact force of this outside is delivered on adjustment sleeve, owing to being provided with elastic seal ring between adjustment sleeve and adjustment seat, this impact force can be made to obtain cushioning for the first time.Simultaneously, irregular for direction impact force can be delivered in adjustment seat by adjustment sleeve, this impact force is converted to the end thrust promoting above-mentioned adjustment seat and slide on aforementioned interior pipe, namely in this course the pressure direction of outside is converted to consistent with spring-compressed direction.Subsequently, this adjustment seat promotes spring-compressed again, makes outside impact force obtain second time damping.Then, this thrust is passed on damper bar, obtains third time damping.
