Abstract
A vibratio-damping stabilizer for vehicle for preventing the overtilt of vehicle body when it is made by a turn, accelerated or declerated features that an additional acceleration sensing plunger is installed to existing vibration damper and the sensed acceleration signal is used to control the open or close of compression damping hole on the piston of vabration damper, so stabilizing the vehicle.
Description
The present invention relates to vehicle shock absorber and stabilizer antiroll bar.
Shock absorber is the indispensable device of modern automobile, but traditional shock absorber function is more single, only plays damping of vibrations, and vehicle stabilization shock absorber of the present invention not only has traditional vibration-damping function, can also play the effect of stabilizer antiroll bar, and better than adopting traditional stabilizer antiroll bar.Employing the present invention, even can make automobile adopt the low-down elastic element of rigidity, the also unlikely excessive inclination of generation when turning to can reduce automobile vehicle body when acceleration and sudden stop simultaneously greatly and swing back and lean forward.
The rigidity of the elastic element of the general luxury car of design philosophy is less, bigger inclination takes place easily in Vehicular turn, thereby usually need to install stabilizer antiroll bar, the inclination of vehicle body when reducing to turn to.Independence to each wheel suspension can cause adverse effect behind the stabilizer antiroll bar but install additional, and the present invention is just in order to overcome this shortcoming.Design philosophy of the present invention is, on traditional shock absorber, install the acceleration induction plunger additional, the acceleration/accel of vehicle body when being used for responding to motor turning and car acceleration, deceleration, pass to shock absorber after this acceleration/accel changed into pressure signal, the unlatching and the closure in compression damping hole in the control shock absorber, make shock absorber effect of playing stably in motor turning and acceleration and deceleration, reduce vehicle body bevelled amplitude all around.
The structural representation of forming the vehicle stabilization shock absorber that structure designs according to above-mentioned thought as shown in Figure 1, as seen from the figure, the vehicle stabilization shock absorber is to transform on the basis of traditional shock absorber, installed functional component additional, mainly be: the upper side at piston rod adds two acceleration induction plungers (1), acceleration induction plunger (1) can be in sleeve (3) certain limit slide, the axis of two acceleration induction plungers should be in horizontal surface, and orthogonal.In shock absorber piston rod (2), have through hole (4), be used for the hydraulic pressure power transmission.Side in the compression damping hole (7) of damper piston (9) has pilot hole (10), communicate with through hole (4), the wedge shape plunger (12) that dams is housed in the pilot hole (10), and throttling plunger design wedgewise is for the better variation of induction damping liquid (11) pressure.Other parts all adopt the prior art structure.Accompanying drawing 1 mainly plays explanation signal effect, and the certain structures details is not drawn one by one, for example: be processing pilot hole (10), need hole from the cylinder of piston (9), also not shown among the figure.Vehicle stabilization shock absorber shown in the accompanying drawing 1 is equipped with two acceleration induction plungers, an acceleration/accel that produces when being used to respond to motor turning, acceleration/accel when another is used to respond to the automobile acceleration and deceleration, wherein be used to respond to the acceleration induction plunger of automobile acceleration and deceleration and nonessential, can be provided with as required.The correlation parameter of part will be determined as the case may be.
One end of installation requirement vehicle stabilization shock absorber piston rod should link to each other with vehicle body (vehicle frame), and an end of clutch release slave cylinder should link to each other with wheel.Because an acceleration induction plunger of vehicle stabilization shock absorber can only respond the acceleration/accel of a direction, therefore, when mounting vehicle is stablized shock absorber, the acceleration/accel the when direction that should guarantee two acceleration induction plungers can be distinguished centrifugal acceleration when correctly responding motor turning and car acceleration and slows down.
The working process automobile is at the uniform velocity straight when travelling, because the axis of two acceleration induction plungers is in horizontal surface, acceleration/accel in can only the level of response face, the acceleration/accel that automobile vibrates down in vertical direction can not respond by degree of being accelerated induction plunger, this moment, the pressure of the damping liquid that wheel bounce produces can make the wedge shape plunger that dams return in the pilot hole, the wedge shape plunger that dams does not work the effect of damming, and the vehicle stabilization shock absorber only plays damping of vibrations.When motor turning, the centrifugal acceleration that produces by turning to can be by an acceleration induction plunger response, under action of centrifugal force, relevant acceleration induction plunger moves in sleeve, liquid in the compression through hole (4), thereby the wedge shape plunger (12) that dams is released from pilot hole (10), and then compression damping hole (7) are sealed.Because compression damping hole (7) is closed, the piston of shock absorber (9) will stop compression stroke, thereby prevent the inclination of automobile.If this moment, wheel was subjected to bigger upwards impacting certainly, when making the pressure of the damping liquid (11) of shock absorber bottom push back pilot hole (10) even as big as plunger (12) that wedge shape is dammed, compression damping hole (7) will reopen, the damping of vibrations of bringing into normal play again.The vehicle stabilization shock absorber is similar to the response process and the said process of automobile acceleration and deceleration, does not repeat them here.
In appended drawings 1 and the Figure of abstract: acceleration induction plunger (1), piston rod (2), sleeve (3), through hole (4), clutch release slave cylinder (5), reed (6), compression damping hole (7), uphold damping hole (8), piston (9), pilot hole (10), damping liquid (11), the wedge shape plunger (12) that dams
Damper for vehicle stabilization structure of the present invention is simpler, respond well, be particularly suited for medium-to-high grade car, Use on the vehicles such as offroad vehicle.
Claims (1)
1, a kind of vehicle stabilization shock absorber is characterized in that: installed the acceleration induction plunger additional on the piston rod of existing shock absorber, in order to the acceleration/accel of sense vehicle when turning to acceleration and deceleration; Have through hole in the piston rod, liquid is wherein arranged in order to transmit the pressure signal of acceleration induction plunger; The side in the compression damping hole of piston has pilot hole, and the wedge shape plunger that dams is housed in the pilot hole slidably, wedge shape can dam when being subjected to the pressure that the acceleration induction plunger the passes over compression damping hole of piston of plunger of damming.
