Connect, can speed up the quick response of vehicle suspension, improve the handling of driver and conductor's comfort level and driver.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the inertial flywheel upper side structure diagram of the present invention.
Embodiment
As illustrated in fig. 1 and 2, the change passive suspension energy absorption device of inertia vehicle disclosed by the invention includes：Bidirectional hydraulic hinders
Buddhist nun's device 1, hydraulic motor 2, inertial flywheel 4 and flywheel-bracket 3；Hydraulic motor 2 passes through flywheel-bracket 3 and di-directional hydraulic damper
1 is fixedly mounted；Inertial flywheel 4 is fixedly mounted on the output shaft of hydraulic motor 2；In the upper and lower ends of di-directional hydraulic damper 1
An oil inlet and outlet is respectively equipped with side wall；Be internally provided with piston 7 in di-directional hydraulic damper 1, and positioned at upper and lower two into
Between oil outlet；Piston push rod 6 is equipped with piston 7, and the lower end of piston push rod 6 is vertically through di-directional hydraulic damper 1
Bottom；The dextrorotation oil inlet and derotation oil inlet of hydraulic motor 2 by two oil pipes 5 respectively with di-directional hydraulic damper 1
Upper and lower two oil inlet and outlets are connected.
Wherein, inertial flywheel 4 is disc flywheel；Four T-shaped sliding slots 8, and four are equipped with the upper side of inertial flywheel 4
The radial direction of a T-shaped sliding slot 8 along inertial flywheel 4 is in crossing distribution；Slidingtype is all provided with four T-shaped sliding slots 8 and is embedded with T-shaped slider
9；The support being resiliently supported in T-shaped slider 9 compression spring 10 is respectively equipped with the both ends of T-shaped sliding slot 8.Damped in bidirectional hydraulic
The upper end of device 1 is equipped with upper retainer ring, and lower retainer ring is equipped with the lower end of piston push rod 6.
The inertial flywheel 4 of the present invention is different from conventional monolithic flywheel structure, symmetrically adds in inertial flywheel overall structure
Work T-shaped sliding slot 8, the intermediate distribution T-shaped slider 9 that can be slided identical in quality, in 9 the right and left of T-shaped slider installation model, greatly
Small consistent support compression spring 10.
During work, become the passive suspension energy absorption device of inertia vehicle and fixed by upper retainer ring and lower retainer ring with vehicle,
When there is fluctuating on road surface, wheel contacts the fluctuating on road surface being delivered to ground becomes the passive suspension energy absorption device of inertia vehicle,
When track is up gradient or is raised, the piston push rod 6 of di-directional hydraulic damper 1 moves upwards, di-directional hydraulic damper 1
The liquid of the middle top of piston 7 is extruded, and cavity pressure increase, the dextrorotation oil inlet of hydraulic motor 2 is flowed liquid into by oil pipe 5
Mouthful, flywheel turns are driven, energy conservation equation is：
I （Rotary inertia）= mr2（1）
E（The moment of momentum）= ½ I×ω（Angular speed）（2）
By（1）Since centrifugal force acts on when formula can be seen that rotation, the rotary inertia of inertial flywheel 4 is gradually increased.By
（2）Formula understands that, when rotary inertia gradually increases, system absorbs energy and will accelerate at this time, while improves suspension response speed, increases
The comfort level of driver and conductor and driver's is handling.It is conversely, as the same.And conventional damper is not due to having energy absorption work(
Can, so suspension response speed does not have quick response function.
