Embodiment 1
As shown in Figures 1 to 4, the vehicle shock absorber of the adaptive damping of the present embodiment, including work cylinder barrel 1, oil storage cylinder barrel
2, piston 3, piston rod 4, the first chassis 5, the second chassis 6, spool 7, spring 8 and electromagnet 9；
Work cylinder barrel 1 is mounted in oil storage cylinder barrel 2, and piston rod 4 is connect with piston 3, and piston 3 is located in work cylinder barrel 1, living
The first check valve 12 and second one-way valve 13, the conducting direction phase of the first check valve 12 and second one-way valve 13 are provided on plug 3
Instead；
Space between work cylinder barrel 1 and oil storage cylinder barrel 2 is known as oil storage cavity 11；
The bottom of work cylinder barrel 1 is provided with the first chassis 5 and the second chassis 6, first passage 14, third check valve 15 and
Four check valves 16 are located in the first chassis 5, and first passage 14 is connected to inner cavity and the oil storage cavity 11 of work cylinder barrel 1；Second channel
17, the 5th check valve 18 and the 6th check valve 19 are located in the second chassis 6, are provided with oil passage 10, oil liquid in the first chassis 5
Channel 10 is connected to inner cavity and the second channel 17 of work cylinder barrel 1, and second channel 17 is connected to oil storage cavity 11；
The third check valve 15 and the 4th check valve 16 in parallel relationship, third check valve 15 are provided in first passage 14
It is opposite with the conducting direction of the 4th check valve 16；
It is provided in second channel 17 in the 5th check valve 18 of parallel relationship and the 6th check valve 19, the 5th check valve 18
It is opposite with the conducting direction of the 6th check valve 19；
Spring 8 is mounted between spool 7 and the second chassis 6, and spool 7 can be opposite under the action of electromagnet 9 and spring 8
Second chassis 6 moves back and forth.
The damper of the present embodiment has small damping and greatly two kinds of working conditions of damping, and working principle is respectively:
(1) small damping state；As depicted in figs. 1 and 2, electromagnet 9 powers off, and spool 7 is under the action of spring 8 far from second
Channel 17, second channel 17 are connected to inner cavity and the oil storage cavity 11 of work cylinder barrel 1 with oil passage 10 jointly.When piston rod 4 by
After drops, the oil liquid in the lower cavity 20 below of piston 3 receives extruding, oil liquid by the first check valve 12 on piston 3 into
Enter the upper plenum 21 of 3 or more piston；Since the piston rod 4 entered in work cylinder barrel 1 occupies more and more volumes, upper plenum 21
Interior increased space is less than the space of reduction in lower cavity 20, and a part of oil liquid has to pass through 14 He of first passage in lower cavity 20
Third check valve 15 enters oil storage cavity 11；Since second channel 17 and first passage 14 are parallel relationship, also some is oily
Liquid enters oil storage cavity 11 by oil passage 10, second channel 17 and the 5th check valve 18.When 4 uplink of piston rod, oil liquid
Similarly, the check valve only to work is from the first check valve 12 becomes second one-way valve 13, third check valve 15 becomes for glide path
4th check valve 16, the 5th check valve 18 become the 6th check valve 19.
(2) big damping state；As shown in Figure 3 and Figure 4, electromagnet 9 is powered, uplink pressure under the action of electromagnet 9 of spool 7
Contracting spring 8 simultaneously blocks second channel 17.After piston rod 4 is by drops, the oil liquid in the lower cavity 20 below of piston 3 receives crowded
Pressure, oil liquid enter the upper plenum 21 of 3 or more piston by the first check valve 12 on piston 3；Due to entering in work cylinder barrel 1
Piston rod 4 occupies more and more volumes, and increased space is less than the space of reduction in lower cavity 20, lower cavity in upper plenum 21
A part of oil liquid has to pass through first passage 14 in 20 and third check valve 15 enters oil storage cavity 11.When 4 uplink of piston rod, oil
Similarly, the check valve only to work becomes second one-way valve 13, third check valve 15 from the first check valve 12 to the glide path of liquid
Become the 4th check valve 16.
When second channel 17 is opened, the number of channels between 1 inner cavity of work cylinder barrel and oil storage cavity 11 increases, work
The oil liquid flow made between 1 inner cavity of cylinder barrel and oil storage cavity 11 increases therewith, and the speed of 4 uplink and downlink of piston rod faster, subtracts
The damping of vibration device is smaller；Conversely, the damping of damper increases after second channel 17 is closed.
Although the embodiments of the present invention is illustrated in specification, these embodiments are intended only as mentioning
Show, should not limit the protection scope of the utility model.Various omissions are carried out in the range of not departing from the utility model aims, are set
It changes and change should be included in the protection scope of the utility model.
