Embodiment
As shown in Figure 1, the present invention includes cylinder body 1, floating piston 2, piston 3 and piston rod 4.Floating piston 2 and piston 3 are positioned at cylinder body 1, all with cylinder body 1 inner wall sealing, contact, and floating piston 2 is on piston 3, and floating piston 2 and piston 3 mark off compressed air cell a, upper oil cavitie b and lower oil cavitie c by cylinder body 1, injecting oil liquid in upper oil cavitie b and lower oil cavitie c.Piston rod 4 is connected with piston 3, and stretches out outside cylinder body 1 lower end from cylinder body 1.The dither that compressed air cell a can reduce wheel effectively to be produced while being subject to impacting suddenly, and compensation is because piston rod 4 enters in cylinder body 1, the reduction of cylinder body 1 oil storage volume.Be externally connected to pipeline d at cylinder body 1, the two ends of pipeline d connect respectively upper oil cavitie b and lower oil cavitie c, make the fluid between upper oil cavitie b and lower oil cavitie c form oil hydraulic circuit by pipeline d.Oil hydraulic motor 6 is set on described oil hydraulic circuit, and the oil hydraulic motor 6 of flowing through of the fluid in pipeline d, drive oil hydraulic motor 6 to rotate.Oil hydraulic motor 6 connects flywheel 7, and flywheel 7 connects damper regulation mechanism 8, and damper regulation mechanism 8 connects generator 9.
As shown in Figure 2, pipeline d is comprised of four branch road d1, d2, d3, d4.Branch road d1 head end is connected with cylinder body 1, and with upper oil cavitie, b is communicated with, and branch road d1 tail end is connected with oil hydraulic motor 6 tops, is provided with one-way valve 11 in the middle of branch road d1; Branch road d2 head end is connected by the three-dimensional flowing valve with branch road d1, and branch road d2 tail end is connected by the three-dimensional flowing valve with branch road d4, is provided with one-way valve 10 in the middle of branch road d2; Branch road d3 head end is connected by the three-dimensional flowing valve with branch road d1, and branch road d3 tail end is connected by the three-dimensional flowing valve with branch road d4, is provided with one-way valve 12 in the middle of branch road d3; Branch road d4 head end is connected with cylinder body 1, and with lower oil cavitie, c is communicated with, and branch road d4 tail end is connected with oil hydraulic motor 6 bottoms, is provided with one-way valve 5 in the middle of branch road d4.Fluid in the pipeline d oil hydraulic motor 6 of flowing through, drive oil hydraulic motor 6 to rotate.Four one- way valves 5,10,11,12 are divided into two groups, one- way valve 5,11 is first group of one-way valve, allow the fluid of the upper oil cavitie b rear inflow lower oil cavitie of described oil hydraulic motor 6 c that flows through, one- way valve 10,12 is second group of one-way valve, allows the fluid of the lower oil cavitie c rear inflow upper oil cavitie of oil hydraulic motor 6 b that flows through.Due to the effect of one- way valve 5,10,11,12, make fluid in the pipeline d oil hydraulic motor 6 of flowing through all the time from top to bottom.
As shown in Figure 3, when compression stroke, piston 3 moves upward, upper oil cavitie b fluid is flowed through one-way valve 11, oil hydraulic motor 6, one-way valve 5 to lower oil cavitie c, due to now, one-way valve 12 upper end oil liquid pressures are greater than lower end, and one-way valve 10 right-hand member oil liquid pressures are greater than left end, therefore, fluid can not pass through one- way valve 10,12; As shown in Figure 4, when extension stroke, piston 3 moves downward, lower oil cavitie c fluid flow through one-way valve 10, oil hydraulic motor 6, one-way valve 12 is to upper oil cavitie b, and because one-way valve 11 right-hand member oil liquid pressures now are greater than left end, one-way valve 5 left end oil liquid pressures are greater than right-hand member, therefore, fluid can not pass through one-way valve 5,11.So, the oil hydraulic motor 6 of from top to bottom flowing through all the time of the fluid in pipeline d.Flywheel 7 is fixedly linked with the output shaft of oil hydraulic motor 6, thereby flywheel 7 is rotated around same direction.
As shown in Figure 5, when providing for shift fork 14 tops the axis that is parallel to driven shaft 16 with Electrohydraulic push rod and during towards the thrust F of flywheel 7, bearing 19 provides axial thrust for follower 13.During vibration damper work, fluid flows and makes flywheel 7 rotations; During original state, Electrohydraulic push rod is not worked, impacting force due to spring 17, between flywheel 7 and follower 13, be stiction, constraint due to spline, drive driven shaft 16 and rotate, the resistance maximum that now damper regulation mechanism 8 provides for oil hydraulic motor 6, the charging load impedance that the source of resistance is generator 9; Thereby in 6 couples of pipeline d of oil hydraulic motor, the fluid flow resistance reaches maximum, i.e. the damping of vibration damper is maximum value.When Electrohydraulic push rod, shift fork 14 is provided the axis that is parallel to driven shaft 16 thrust towards flywheel 7
FThe time, 19 pairs of followers 13 of bearing apply axial thrust, and direction is contrary with spring 17 elastic force; Thereby the impacting force of 13 pairs of flywheels 7 of follower can be by maximum vanishing, and now the source of resistance is force of sliding friction
F S ,
F S =
μ N,
μFor dynamic friction factor,
NFor impacting force.Impacting force
NReduce force of sliding friction
F S Reduce, the damping of vibration damper is corresponding reducing also.When follower 13 breaks away from flywheel 7, the suffered frictional force of flywheel 7 is zero, and resistance of shock absorber is minimum value, only by pipeline d, provides damping.Therefore, this mechanism damping of electrodeless adjusting vibration damper within the specific limits in theory.
When road conditions are good, in order to improve the smoothness of vehicle, vibration damper requires to provide large damping.Now, Electrohydraulic push rod is not worked, and by spring 17, provides impacting force, and flywheel 7 forms with mass motion with follower 13, thereby drives driven shaft 16 rotations; The interior flow resistance to fluid of vibration damper is provided by the charging load impedance of pipeline d and generator 9, is large damping state.Driven shaft 16 is connected with generator 9, and the vibrational energy of vibration damper is converted into to electric energy.
When road conditions are severe, in order to improve the smoothness of vehicle, vibration damper requires to provide little damping.Now, Electrohydraulic push rod work, apply and be parallel to the thrust of driven shaft 16 axis towards flywheel 7 shift fork 14 tops, and 19 pairs of followers 13 of the bearing of shift fork 14 bottoms apply axial thrust, the elastic force opposite direction provided with spring 17; The impacting force of 13 pairs of flywheels 7 of follower reduces, and the suffered frictional force of flywheel 7 reduces; The now damping of vibration damper starts to reduce.When the thrust applied when 19 pairs of followers 13 of bearing equals spring 17 elastic force, flywheel 7 separates with follower 13, and the frictional force that now 13 pairs of flywheels 7 of follower apply is zero; Therefore oil liquid resistance is only provided by pipeline d.Now resistance of shock absorber is minimum value.
During different road conditions, by controlling the thrust of Electrohydraulic push rod to shift fork 14, the damping of vibration damper is not identical yet, can so that vehicle according to the fine or not adjustable suspension damping size of the road conditions of travelling to realize the optimal control of semi-active suspension.The vibrational energy of vibration damper is converted into electric energy, has not only reclaimed energy, clean environment firendly, and reached the reduction oil liquid temperature, make vibration damper keep the function of premium properties.
