Abstract
The utility model discloses a gas and oil hybrid hydraulic front shock absorber for electric vehicles, which comprises a vertical column and two fork bodies arranged symmetrically from left to right.Each fork body comprises a handle tube and an aluminum tube, the lower end of the handle tube is inserted inside the aluminum tube, the handle tube can move vertically relative to the aluminum tube, asealing structure is arranged between the handle tube and the aluminum tube so as to form a sealing cavity inside the handle tube and the aluminum tube, and the upper end of the handle tube is provided with a valve. By arranging the valves at the upper ends of the handle tubes, shock absorption damping intensity can be regulated freely by regulating airflow rate in the sealing cavities formed bythe handle tubes and the aluminum tubes, thereby flexibly regulating 'soft and hard' comfort degree of shock absorption.
Description
Technical field
The utility model relates to the preceding damping of the hybrid hydraulic pressure of a kind of electric vehicle oil gas.
Background technology
At present, the battery-driven car front fork mainly adopts the form of the preceding damping of rocker-arm, hydraulic pressure or the preceding damping of imitative hydraulic pressure.It is all sealed after damping production is finished before the common hydraulic pressure, its in-to-in hydraulic pressure oil mass can't change again, so degree of damping also can't carry out follow-up adjustment, thereby can't adjust damping " soft or hard " comfort level flexibly, makes the battery-driven car front fork can't reach best damping effect.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of hybrid hydraulic pressure of electric vehicle oil gas simple in structure, that can effectively improve damping effect preceding damping.
For achieving the above object, damping before the hybrid hydraulic pressure of the utility model electric vehicle oil gas, comprise column and left and right symmetrically arranged two fork bodies, wherein, the fork body comprises handle pipe and aluminum barrel, and the lower end of handle pipe is inserted into the inside of aluminum barrel, aluminum barrel is up and down relatively for the handle pipe, be provided with hermetically-sealed construction between handle pipe and the aluminum barrel,, be provided with tire tube valve in handle pipe upper end so that the inside of handle pipe and aluminum barrel forms annular seal space.
Further, be provided with the hydraulic shock-absorption assembly in the described annular seal space, this hydraulic shock-absorption assembly comprises hydraulic oil, nitrogen and the spring assembly that is arranged in the described annular seal space.
Further, described spring assembly comprises upper spring, middle damping spring and following damping spring, the lower end of described aluminum barrel has been bolted to connection a push rod, be set with down damping spring, ring gear, ring gear seat, middle damping spring on this push rod direction from bottom to top successively, ring gear is fixedly installed on the ring gear seat, captive joint with the ring gear seat in the upper end of following damping spring, the upper end of push rod is set with the top, and middle damping spring is arranged between top and the ring gear seat; The two ends of upper spring are resisted against respectively between the upper end and top of described handle pipe.
Further, described hermetically-sealed construction comprises cover of dust and oil sealing, and this cover of dust seal cover cap is contained in the upper port place of described aluminum barrel, and the inwall at described aluminum barrel upper port place is provided with oil sealing.
Further, described tire tube valve is provided with the anti-gas-leak structure.
The utility model is by being provided with tire tube valve in handle pipe upper end, make to form gas flow in the annular seal space by adjusting handle pipe and aluminum barrel, can adjust the damping degree of damping freely, thereby reach the purpose of sensitive adjusting damping " soft or hard " comfort level.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As shown in drawings, damping before the hybrid hydraulic pressure of the utility model electric vehicle oil gas, comprise column 1 and left and right symmetrically arranged two fork bodies 2, wherein, fork body 2 comprises handle pipe 3 and aluminum barrel 4, the lower end of handle pipe 3 is inserted into the inside of aluminum barrel 4, and handle pipe 3 aluminum barrel 4 relatively is up and down, is provided with tire tube valve 16 in handle pipe 3 upper ends.Be provided with hermetically-sealed construction between handle pipe 3 and the aluminum barrel 4, hermetically-sealed construction comprises cover of dust 14 and oil sealing 15, cover of dust 14 seal cover caps are contained in the upper port place of aluminum barrel 4, and the inwall at aluminum barrel 4 upper port places is provided with oil sealing 15, and cover of dust 14 and oil sealing 15 make the inside of handle pipe 3 and aluminum barrel 4 form annular seal space 5.Be provided with the hydraulic shock-absorption assembly in the annular seal space 5, the hydraulic shock-absorption assembly comprises hydraulic oil, nitrogen and the spring assembly that is arranged in the annular seal space 5.Common tire tube valve gets final product in the tire tube valve 16 employing prior aries, by tire tube valve 16 unidirectional in annular seal space 5, inflating, tire tube valve 16 is provided with the anti-gas-leak structure, inflation back gas can not be revealed by tire tube valve 16 freely, but but the people makes the valve inside conducting for applying external force, with the gas flow in the flexible increase and decrease annular seal space 5.By being provided with tire tube valve 16 in handle pipe 3 upper ends, the feasible nitrogen amount that passes through to adjust in the annular seal space 5 can be adjusted the damping degree of damping freely, thereby reaches the purpose of preceding damping " soft or hard " comfort level of the hybrid hydraulic pressure of sensitive adjusting the utility model electric vehicle oil gas.
Wherein, spring assembly comprises upper spring 6, middle damping spring 7 and following damping spring 8, the lower end of aluminum barrel 4 is fixedly connected with a push rod 10 by bolt 9, be set with down damping spring 8, ring gear 11, ring gear seat 12, middle damping spring 7 on push rod 10 direction from bottom to top successively, ring gear 11 is fixedly installed on the ring gear seat 12, captive joint with ring gear seat 12 in the upper end of following damping spring 8, the upper end of push rod 10 is set with top 13, and middle damping spring 7 is arranged between top 13 and the ring gear seat 12; The two ends of upper spring 6 are resisted against the upper end of handle pipe 3 respectively and come directly towards between 13 the upper surface.
The utility model can charge into a certain amount of nitrogen by tire tube valve 16 in annular seal space 5, make it to mix with hydraulic oil according to a certain percentage, thereby reach oil, the common damping of gas about, reach the effect of effective control damping degree of damping.Damping can better adapt to the different ground-surface substantive requirements of form such as city, rural area before the hybrid hydraulic pressure of the utility model electric vehicle oil gas, and can satisfy different different load-carrying requirements of driving colony, make driving comfort under various environmental factors, all can reach best.
