Description
[technical field]
The utility model relates to a kind of draft hitch, relates in particular to a kind of draft hitch that can prevent vehicle body generation inclination and yaw effectively, belongs to automobile technical field.
[background technology]
One of the modern automobile technology is high speed development day by day, and suspension technology wherein then is to have influence on the road-holding property of automobile and ride comfort, ride comfort, and even the important technology of traffic safety performance.Yet, in the prior art, when vehicle ' is advanced on uneven road surface or with curve mode, be subjected to the vehicle body of suspension carrying that inclination will take place, and therefore suspension guiding leverage will produce relative motion and distortion this moment, and the inclination of the vehicle body of these appearance and yaw problem will have influence on above-mentioned automobile operation and safety performance.To this, can specifically set forth the influence that auto body inclination and yaw problem cause automotive performance from five following aspects, wherein:
The first, (for example for general independent suspension, independent suspension by swinging arms, candle type suspension, McPherson strut, many link-types suspension etc.), when suspension is out of shape, wheel plane will produce and distance--the wheelspan of change both sides wheel and road surface contact point, can cause tire with respect to the ground lateral sliding like this, thereby destroy tire and the ground-surface situation of normally adhering to.In addition, when with this type of suspension application during, can make the orientation angle of stub and camber angle that in various degree variation takes place, thereby affect for handling maneuver in wheel flutter.
The second, modern age automobile suspension generally all very soft, in running at high speed, turn to or when on uneven road surface, travelling, vehicle body can produce bigger lateral inclination and lateral angle vibration, vehicle body will produce corner around roll axis under lateral forces, i.e. vehicle roll angle (angle of roll is an important indicator estimating vehicle handling stability and ride comfort).For road-holding property, excessive angle of roll can make chaufeur feel unstable, dangerous; For ride comfort, the automobile that inclination is excessive, it is uncomfortable that the passenger then can feel.Yet angle of roll is too small, and the roll angular rigidity of suspension is big, when the single wheel of automobile runs into projection or pit, can feel in the compartment to impact, so ride comfort is relatively poor.And the weaving meeting of vehicle body has influence on the directional balance of running car, more seriously, if the yaw velocity of automobile can not be restrained, then can cause automobile to produce the danger of lateral slip or overturning.
Three, when inclination took place, vertical load will be distributed on the left and right side wheel of automobile again, and has influence on the steady state response of automobile.In normal operation, the vertical load of the left and right wheel of automobile equates substantially.But when the automobile curve driving, because the effect of bank moment, vertical load is not what equate on left and right wheel.The cornering behavior that this will influence tire causes the steady state response of automobile to change.At this moment, some vehicle even can become negative understeer from understeer.
Four, when inclination took place, camber angle can change.At this moment, because the suspension form difference, the variation of camber angle has three kinds of situations: remain unchanged, tilt and tilt along the opposite sense of ground side to the reaction force acts direction to the reaction force acts direction along ground side.When body roll, the wheel of dependent suspension keeps plumbness.Top Crossbeam is lacked and the long double cross arm independent suspension of lower cross arm, also can keep its outboard wheels perpendicular to ground substantially, but an inclination is also arranged.Last lower cross arm equal in length and parallel two transverse arms, the tilting of wheels direction of single longitudenal arm independent suspension is opposite with the direction of ground side force, and the effect of increase sideslip angle (absolute value) is arranged.Single cross arm independent suspension is when little lateral acceleration, and wheel tendency direction is identical with the ground side force, and the effect that reduces sideslip angle is arranged.But when big lateral acceleration, the vehicle body that single cross arm independent suspension is housed may significantly be raised, and inboard wheel is liftoff, outboard wheels tilts to force direction against ground side, and sideslip angle increases, and vehicle handling stability degenerates suddenly, so, adopt single cross arm independent suspension now seldom.Therefore during straight-line travelling, because the cause of inclination camber angle, the bob of wheel constantly changes camber angle to automobile on unfairness ground, can produce the variation of corresponding flare side force and has influence on the automobile straight motion stability.
Five, when inclination took place, wheel turning angle can change.In lateral forces under body generation inclination, body roll can cause that steering front wheel rotates around stub, and trailing wheel winds the rotation perpendicular to the ground axis, i.e. the change of wheel turning angle, and it is called as " roll steer ", is also referred to as " the inclination interference turns to ".Different along with the direction of front and back roll steer and numerical value, the understeering amount of automobile may increase or reduce.And, when the automobile with camber steer effect is in straight-line travelling, because the wheel that Uneven road causes also can make wheel produce certain deflection angle with respect to beating of vehicle body, thereby influences the automobile straight motion stability, so modern age, car was tending towards reducing the roll steer amount.
In sum as can be known, inclination and weaving that existing automotive suspension mechanism can't fundamentally solve auto body, thereby can be to road-holding property, the ride comfort of automobile, even the driving safety performance caused very big influence, and therefore needing a kind of improved novel draft hitch badly solves this problem.
