Embodiment
The bottom that among Fig. 11 expression damper and vibration damper are connected with wheel, 2 expression inner springs, 3 expression bottoms are fixed, the outer spring of top movable, 4 expressions are fixed to the ring-shaped friction lining pedestal on outer spring top, 5 representation classes are similar to the friction plate of brake block, the movable braking tinsel that contacts or separate with friction plate of 6 expressions, the top base of 7 expression vibration dampers.This figure represents that spring 3 is locked in the situation of tinsel 6 bottoms.
The expression parts are identical with Fig. 1 among Fig. 2.
11,12,13,14 are rotatable fulcrum, i.e. articulating point among Fig. 3.8,9,10 operating handles for the motion of control tinsel, 8,9 left end and tinsel are affixed, and right-hand member and connecting rod 10 are hinged.Connecting rod 10 moves up and down and can drive tinsel and hold tightly or separate friction plate in the middle of being positioned at.Connecting rod 10 links to each other with vehicle brake, is driven by vehicle brake.
Fig. 4 represents that spring 3 is locked in the situation on tinsel 6 tops.
Present principles vibration damper free travel is fit to do longlyer than general vibration damper.Original state will allow the chassis operate on the liftoff medium position, and spring 3 tops can be free movable; In case of necessity: spring 3 tops are locked in diverse location by quick clamping tinsel 6 on demand when the vehicle operating tire is beated.The firm softness of the high and low position decision vibration damper on spring 3 tops; When a high position, spring 3 may be in extended state, and vibration damper is in soft state; Spring 3 generally is in compressive state when low level, and vibration damper is in hard state.The vibration damper of each wheel correspondence can independently be controlled.For ease of understanding, roughly vibration damper state and controlling method are described with following several situations.
General walking states: this moment, the chassis was in medium altitude, and metallic moving plate 6 separates with friction plate 5, and only support car weight with a spring 2 this moment, and whole vibration damper is in than soft state, and free travel is bigger, and this moment, the vehicle driving smoothness was better.
Turn condition: such as left-hand bend, because centrifugal action, vehicle has flare trend, and this moment, right row wheel was subjected to bigger power.About row be suspended on turning initial stage tinsel braking lock live shell spring 3, right row hung and obtained spring 2, spring 3 common pressure bearing capacities this moment, suspension stiffness is strengthened greatly, and the movable spring in the left bank suspension might be in extended state, reduce the bearing capacity that left bank hangs, this moment, intact stability was better.
High acceleration mode: the vehicle high new line trend of quickening to have that starts to walk at a high speed.The real suspension of lock this moment can be reduced the new line amplitude.
The brake deceleration state: the vehicle trend of bowing, promptly people are said nods, and real suspension of lock this moment effectively reduced the amplitude of bowing, and improves to drive travelling comfort.
Motor pattern: when the vehicle rider needs walking at a high speed, maybe will reduce windage, maybe will improve reasons such as stability, this moment, substep when the wheel high jump locked the suspension of four-wheel step by step, up to lock actual arrival relevant position.This moment, outer spring 3 may be in extended state, and being suspended on extended end can be very soft, and suspension strut power is equivalent to inner spring 2 pressure and deducts the outer spring pulling force; At the serrated end support force is that two spring pressures are made a concerted effort, and hangs hardening.This moment, vehicle chassis was lowered.High back is low or low early and high after before vehicle needs, or high right low, a right high left side, a left side is when hanging down state, and locking phase should hang and can obtain or improve this state step by step.
High chassis state: the movable spring that all hangs is locked onto low level, and load-bearing and road passing ability improve.
Uneven load condition: lock the low level that is hanging at heavier position, obtain load-bearing and improve.
Overweight state: locking four is hanging to low level and is improved.
Allow friction plate to slide along tinsel contacting generation frictional force with tinsel when, the degree of adjusted of suspension stiffness, damping is better at this moment, and suspension behavior is better.This moment, friction disc wear can aggravate.
It may be noted that above pattern can not obtain sometimes simultaneously, the state that has can not obtain immediately.The power of locking tinsel derives from the vehicle hydraulic driver, and the electric controller of direct current generator and so on maybe can be set for suspension, and driving force is controlled by vehicle-mounted computer, only makes brief description for ease of understanding at this.
