Detailed description of the invention is as follows:
In FIG, left front vibration damper assembly (1), right front vibration damper assembly (2), left back vibration damper assembly (3) right back vibration damper assembly (4) connect as one vehicle body and fore suspension and rear suspension.Front and back bumper is divided into two groups of duplicate unit of principle of work.Two unit are controlled by a starting switch assembly (6).Automobile principle of work when normal traveling is as follows:
When car is when normally travelling, four cover bumpers only have the function of damping, when bumper is under pressure compression, top cylinder epicoele (12) (27) pressure increase, flow regulating valve (14) (26) open automatically, damping oil is flowed out by flow regulating valve (14) (26) and is passed through three-way pipe (15) (39) and is divided into two-way, leading up to dual control machinery valve assembly (8) and three-way pipe (16) is back to and stores oil sump (44), separately lead up to flow regulating valve (40, (43) and piston rod (35) (41) get back in the middle of doffing epicoele (21) (33).After doffing cavity of resorption (23) (37) damping oil carries out augmenting to doffing exocoel (19) (31) by oilhole (24) (38), unnecessary damping oil is flowed out by oilhole (22) (32) and can manage (36) (16) through three and be back to and store oil sump (44).
When the rear resilience of bumper compression, top cylinder epicoele (12) (27) pressure reduces, and flow regulating valve (14) (26) are closed to minimum automatically.Pressure increase in lower simple epicoele (21) (33), flow regulating valve (40) (43) are closed to minimum automatically.The damping oil of doffing epicoele (21) (33) is subject to resistance when being forced through flow regulating valve (40) (43), play shock damping action, force to augment damping oil to top cylinder epicoele (12) (27) by flow regulating valve (14) (26) again with after storing that oil sump (44) is inner and being converged by the damping oil of dual control machinery valve assembly (8) afterwards by three-way pipe (16) at three-way pipe (15) (39) place by the damping oil of flow regulating valve (40) (43), play shock damping action.Doffing cavity of resorption (23) (37) pressure reduce, by store the inner damping oil of oil sump (44) by three can manage (36) (16) again pass through oilhole (22) (32) and doffing exocoel (19) (31) doffing cavity of resorption (23) (37) are augmented.Above two processes only have the effect of bumper.
Below with casehistory anti-rolling function during automobile high-speed turnon left:
When automobile is in the moment of carrying out bend, produce a very little centnifugal force.Now the on off controller (7) of starting switch assembly (6) is by the effect of centnifugal force, slide to the right, starting switch assembly (6) left side circuit is opened, and the inner electromagnet 1 of dual control machinery valve assembly (8) is started working.Valve body slides left, the valve closing on dual control machinery valve assembly (8) the right.After entering bend, centnifugal force increases further, it is larger that right front vibration damper assembly (2) right back vibration damper assembly (4) is compressed power, now top cylinder epicoele (12) pressure increase, flow regulating valve (14) is opened automatically, and damping oil is flowed out by flow regulating valve (14) and passes through three-way pipe (15) gets back to doffing epicoele (33) formation permeator by flow regulating valve (40) and piston rod (35) again.Other oil circuit is constant.Cross-sectional area due to top cylinder epicoele (12) is greater than the cross-sectional area of doffing epicoele (33).So, the ratio of the cross-sectional area of the ratio of the reduction length of top cylinder epicoele (12) and the spread length of doffing epicoele (33) and the cross-sectional area of top cylinder epicoele (12) and doffing epicoele (33) is inversely proportional to.The cross-sectional area of top cylinder epicoele (12) (27) reasonable in design according to the requirement of different automobile types and the ratio of doffing epicoele (21) (33) control the equidirectional barycentre offset of vehicle body to turn direction.Due to left front vibration damper assembly (1), right front vibration damper assembly (2), left back vibration damper assembly (3), right back vibration damper assembly (4) all receives the compression that centnifugal force is converted into pressure, so the center of gravity of vehicle body also entire lowering.So just can better prevent automobile from occurring the probability of turning on one's side when running at high speed.When automobile enters straight-line travelling, centnifugal force disappears, and starting switch assembly (6) left side circuit is closed.Bumper enters normal motoring condition.
Such as: designing the transversal and long-pending of epicoele (12) (27) of certain car with the ratio of doffing epicoele (21) (33) is 1.3:1, when car is turned left, time right front vibration damper assembly (2) right back vibration damper assembly (4) have compressed 10mm, left front vibration damper assembly (1) left back vibration damper assembly (3) corresponding compression 13mm.So the direction skew contrary with turn direction does not appear in the center of gravity of vehicle body, but slightly offset by a bit to the equidirectional of turn direction, the center of gravity of vehicle body also reduced more than 10mm.So automobile is just prevented to occur the probability of turning on one's side when running at high speed.
