Further, hydraulic oil is full of in described piston rod, assistant cylinder and bearing.
Further, be provided with floating piston in described piston rod, described floating piston is arranged in piston rod, and described floating piston is connected with described piston rod moving sets, and piston rod is divided into left chamber and right chamber by described floating piston.
Further, described left chamber is full of nitrogen, and described right chamber is full of hydraulic oil.
The beneficial effects of the utility model are, this energy absorbing bumper actv. make use of the mode of operation of gas buffer, liquid throttling vibration damping, and operating characteristic is more stable, produce and restore power, bumper/spoiler is resetted after clashing into by nitrogen.
Accompanying drawing explanation
Fig. 1: former bumper structure schematic diagram;
Fig. 2: hydraulic cushion type bumper/spoiler of the present utility model.
In figure: 1, whippletree 2, whippletree medial reinforcement 3, left chamber 4, piston rod 5, floating piston, 6, right chamber 7, cutoff port 8, assistant cylinder 9, bearing.
Specific embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " top ", " end " " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristic.Thus, be limited with " first ", the feature of " second " can express or impliedly comprise one or more these features.In description of the present utility model, the implication of " multiple " is two or more, unless otherwise expressly limited specifically.
In the utility model, unless otherwise clearly defined and limited, the term such as term " installation ", " being connected ", " connection ", " fixing " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
In the utility model, unless otherwise clearly defined and limited, fisrt feature second feature it " on " or D score can comprise the first and second features and directly contact, also can comprise the first and second features and not be directly contact but by the other characterisation contact between them.And, fisrt feature second feature " on ", " top " and " above " comprise fisrt feature directly over second feature and oblique upper, or only represent that fisrt feature level height is higher than second feature.Fisrt feature second feature " under ", " below " and " below " comprise fisrt feature immediately below second feature and tiltedly below, or only represent that fisrt feature level height is less than second feature.
