The up-down vertical is the device that a cover relies on gravity work, comprising: vertical straight-bar, vertical kinetoplast, vertical decide body, kinetoplast bearing, decide that body encircles admittedly, the kinetoplast slide plate, decide body slide plate, lead.The vertical straight-bar is a straight line pole, and its two ends are fixed on the vehicle frame through support.Vertical is decided body and is decided body through two and encircle admittedly and be fixed on the vertical straight-bar, decides body and encircles the inboard admittedly and be fixed on the vertical straight-bar, and its outside is decided body with vertical and is fixed together.It is the vertical kinetoplast that vertical is decided the body inboard; The vertical kinetoplast passes through two kinetoplast bearing suspensions on the vertical straight-bar; Vertical straight-bar and kinetoplast bearing inner ring are fixed together, and vertical kinetoplast and kinetoplast outer race are fixed together, and the vertical kinetoplast can rotate around the vertical straight-bar through the kinetoplast bearing.On the vertical straight-bar, to decide body for two and encircle admittedly and be evenly distributed near the vertical straight-bar two ends, two kinetoplast bearings are evenly distributed in two to be decided between body encircles admittedly.It all is hemicycle cylinder body shape (shape that cylinder is divided into two along the cylinder center shaft) on external form that vertical kinetoplast and vertical are decided body; But the vertical kinetoplast is solid; It is hollow that vertical is decided body, and the vertical kinetoplast can rotate around the vertical straight-bar in vertical is decided body.Be wrapped in two kinetoplast slide plates on the cylinder side of vertical kinetoplast, these two kinetoplast slide plates are arranged in the central authorities of vertical kinetoplast cylinder side equably along straight line, and orientation is consistent with vertical straight-bar direction.The kinetoplast slide plate is a conductive metal sheet, and kinetoplast slide plate and vertical kinetoplast separate with insulating barrier, and two kinetoplast slide plates link to each other with the both positive and negative polarity of power supply with lead respectively.Deciding the body slide plate is fixed on vertical and decides on the internal layer of cylinder side of body; Decide the body slide plate and have four; When the cylinder vertical section of deciding body when vertical kinetoplast and vertical overlaps; Spatially decide the body slide plate and be evenly distributed in the both sides of kinetoplast slide plate in twos along straight line, the kinetoplast slide plate just separates with the edge of deciding the body slide plate.The vertical kinetoplast is decided body with vertical and is not spatially contacted, when the vertical kinetoplast is decided body certain rotation is arranged with respect to vertical, the kinetoplast slide plate just can with decide the body slide plate and contact.Deciding the body slide plate also is conductive metal sheet, decides body slide plate and vertical and decides the body and function insulating barrier and separate.Decide the body slide plate with cornerwise direction in twos a component become two groups; Decide the body slide plate and draw a lead respectively for two in every group; The synthetic main traverse line of two leads in every group, have two main traverse lines then, these two main traverse lines link to each other with the both positive and negative polarity of lifting motor respectively.
Because automobile generally has four wheels, so need the active independent suspension of quadruplet, wherein two covers are responsible for the damping of front and back wheel, and other two covers are responsible for the damping of left and right wheels.The member that the active independent suspension of every cover comprises has: two springs, two expansion links, four spring holder seats, a cover up-down vertical, a lifting motor, a reducing gear, a worm screw rotating shaft, two worm bearings, two up-down worm gears, two Worm Bearings, two worm screw sleeves, two bearing support, an electric machine support, two semiaxis sleeves.Be responsible for the active independent suspension of two covers of front and back wheel damping, a cover is placed on two the semiaxis sleeves and cooresponding vehicle frame of the near front wheel, left rear wheel, on another set of two the semiaxis sleeves and cooresponding vehicle frame that are placed in off front wheel, off hind wheel.Be responsible for the active independent suspension of two covers of left and right wheels damping, a cover is placed on two the semiaxis sleeves and cooresponding vehicle frame of the near front wheel, off front wheel, on another set of two the semiaxis sleeves and cooresponding vehicle frame that are placed in left rear wheel, off hind wheel.Be responsible for the active independent suspension of front and back wheel damping, the arrangement direction of the vertical straight-bar in wherein every cover up-down vertical all is vertical, parallel with horizon in the horizontal direction with the rectilinear direction at the front and back wheel place of homonymy.Be responsible for the active independent suspension of left and right wheels damping, the arrangement direction of the vertical straight-bar in wherein every cover up-down vertical all is vertical, parallel with horizon in the horizontal direction with the rectilinear direction at the left and right wheels place of homonymy.Thus; Two expansion links all can be arranged on each semiaxis sleeve; In order to make these two expansion link set positions reasonable; The set positions of the expansion link in the suspension of this responsible front and back wheel damping is from the inboard nearer end of wheel, the set positions of the expansion link in the suspension of responsible left and right wheels damping at an end far away from the wheel inboard.When four wheels all were on the horizontal surface, each expansion link all was to be fixed on vertically on the semiaxis sleeve, and this also makes expansion link place straight line vertical with plane, vehicle frame place.
Principle of work: when certain wheel runs into obstacle and lifted up; Therefore spring and expansion link will shrink, if but their contraction can't guarantee to make vehicle frame to keep will letting vehicle frame also lift up under the original height unmodified situation thereupon; At this moment the vertical in the vertical of going up and down is decided body and also can have been lifted up thereupon; And the vertical kinetoplast in the up-down vertical can center on the characteristic that the vertical straight-bar rotates through the kinetoplast bearing owing to receive the effect of gravity in addition, and the vertical kinetoplast also can keep attitude constant.Thus, vertical kinetoplast and vertical decide that relative motion has just been arranged between the body, and the kinetoplast slide plate on them with therefore decide the body slide plate and will contact; Because the kinetoplast slide plate is connecting power supply; Connecting lifting motor and decide the body slide plate, at this moment the circuit between power supply and the lifting motor will conducting, and lifting motor begins to rotate; Then driving reducing gear rotates; Reducing gear drives the worm screw rotating shaft and rotates, and the worm screw rotating shaft drives two ends up-down worm gear and rotates rotation round about, and up-down worm gear drives elevating endless screw is rotated; Will in the worm screw sleeve, descend the elevating endless screw of having lifted up an end, and the elevating endless screw of the other end will rise in the worm screw sleeve (this lifting process can be pre-set artificially).This sport causes chain reaction; Because spring has flexible elastic movement, also can with the unbalanced situation of external force under continue fore and aft motion, this motion may continue a period of time; Kinetoplast slide plate in all up-down verticals with decide the body slide plate no longer include contact till; At this moment plane, vehicle frame place will be parallel with horizontal surface, and therefore car body also can be in horizontality, and the passenger does not have sense in the car.If the lifting motor speed of response that uses is enough fast, car body just can keep a kind of horizontality always, inclination or vibrations in a big way can not take place because ground-surface is uneven, and the passenger can feel very steady in the car.When certain wheel runs into obstacle decline, also be same principle, make vehicle body recover horizontality at last.In order to guarantee in the vertical lift process, semiaxis is ruptured, should add the length of universal-joint between major semiaxis and the diff.
The maximum difference of active independent suspension and existing independent suspension is: can let lifting motor utilize the effect of gravity initiatively to make spring in crank motion, obtain best damping apace, than, better effects if faster with hydraulic pressure or the reaction of gas filed damper.And, can avoid the side wear of tire effectively owing to adopt the mode damping of vertical lift, make controlling of vehicle more stable.
Beneficial effect:
Can overcome that inclination takes place existing independent suspension easily, the deficiency of the bad damping phenomenon of nodding, swing back, bounce, waving; Overcome existing independent suspension and tyre side takes place easily, make the deficiency of controlling the difficulty that becomes to the worn-down phenomenon.Can substitute existing independent suspension, make to take to get more comfortable, stable with driving variable.
