The specific embodiment
After the present inventor accepts this purpose research topic, at first the deceleration mechanism of brake errant vehicle has been carried out deep research in conjunction with real train test, think that will lead to the coefficient of friction resistance that changes the road surface comes the basic principle of effect on the deceleration road surface of slowing down for errant vehicle to be: make vehicle all the time or travelling on the road surface that necessarily is absorbed in the degree of depth having of being interrupted, slow down by the resistance acting that overcomes the road surface; If the road surface adopts the material of viscosity that certain energy-absorbing function is arranged, also can make vehicle deceleration.Four aspects that have that make the errant vehicle energy dissipating are arranged in both cases: the acting of pavement compaction resistance; The resistance acting is passed on the road surface; The stagnant loss resistance acting of airtyred bullet; The stagnant loss resistance acting of the bullet of ground surface material.Think thus " decelerability that every factor that can change pavement compaction performance, road surface passing performance or distortion of change vehicle tyre and surface deformation performance can both change the road surface ".
Make full use of factors such as above-mentioned deceleration mechanism and comprehensive comfort level, the road surface of deceleratuib lane should be: make tire all the time or be interrupted be in the viscoelastic medium road surface that a fixed limit is gone into the degree of depth, the road surface form that certain elasticity is arranged, certain cavity is arranged (thereby the certain deformation space is arranged), comfort level can be accepted again by the driver.Vehicle is wanted through out-of-date from this road surface: the acting of pavement compaction resistance is arranged; There is the road surface to pass the resistance acting; There is the stagnant loss resistance acting of airtyred bullet to also have road surface elastic hysteresis energy dissipating.
The present inventor has carried out deep investigation and research to the deceleration ridge structure and the mechanism of action used on present sub-district, parking lot, the road.The conclusion that draws is that this deceleration ridge is inapplicable for brake failure vehicle in long big gug, and its reason is: 1, the prerequisite of its application is to use under the fail-safed situation of brake; 2, its deceleration mechanism is initiatively control speed: it is can cause that by deceleration ridge fierce mechanical oscillation cause the uncomfortable or vehicle damage of body and mind by driver's physiology or mental impression vehicle, thereby conscious, reduce the speed of a motor vehicle on one's own initiative, is a kind of fast measure of initiatively controlling; 3, this deceleration ridge does not have energy-absorbing function, the deceleration poor effect.
And the objective of the invention is vehicle at brake failure on long downslope, can not take brake to wait measure to come control rate, can only make errant vehicle on the downhill path, reduce the speed of a motor vehicle with the resistance of deceleratuib lane itself or the speed of a motor vehicle does not rise, also the degree that the occupant can accept must be guaranteed, thereby said structure can not be directly adopted.
Because gradient sliding force is relevant with the gravity and the gradient of vehicle, under the situation of long and steep downgrade brake failure, because the existence of the sliding force that the gradient produces, make vehicle that the trend of acceleration be arranged, therefore brought unfavorable factor to vehicle deceleration, weakened by the characteristic that changes the road surface or the sliding force of offsetting the gradient is the emphasis of this subject study.Under the situation of long and steep downgrade brake failure, make the improvement project of vehicle deceleration should study resistance to rolling that increases vehicle and the sliding force that creates conditions as far as possible and reduce or offset the gradient emphatically from the research of road aspect.
Studies show that the elasticity deceleration ridge, not only energy-absorbing effect is good especially to have the elasticity deceleration ridge of elastic hysteresis performance, and the vibration situation of vehicle also can be controlled by certain measure.Similar to squeegee action energy-absorbing principle, because the existence of elastic hysteresis phenomenon, the elastic deformation on road surface also can absorb energy, thereby makes vehicle deceleration.When vehicle travelled on the hard pavement, the distortion on road surface can be ignored basically, but on the soft road surface of elasticity, the distortion energy-absorbing on road surface will show as the running resistance of vehicle.The viscoelasticity recovery speed that the big young pathbreaker of running resistance goes into the degree of depth, road surface by the limit of the supporting rigidity on road surface, wheel decides.
