The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
As Fig. 1, Fig. 2 and shown in Figure 3, stiffness variable front hung holder of the present utility model, suspend before comprising two groups, suspend before each group and include one group of master's spring 7, connecting rod 3, damping shock absorption device 6 and two groups of auxiliary springs 8, connecting rod 3 is horizontal arrangement, one end is articulated in operator's compartment 1 bottom, the other end is articulated on the chassis side rail 5, damping shock absorption device 6 bottoms and chassis side rail 5 are hinged, the top of damping shock absorption device 6 and connecting rod 3 are hinged, main spring 7 bottoms are installed in chassis side rail 5 bottoms, main spring 7 tops contact with connecting rod 3, auxiliary spring 8 bottoms are installed in the top airfoil of chassis side rail 5, and two groups of auxiliary springs 8 are divided into the both sides of connecting rod 3 and chassis side rail 5 hinge-points, are provided with the gap between the top of auxiliary spring 8 and connecting rod 3 bottoms.By two groups of auxiliary springs 8 are set below connecting rod 3, the top of auxiliary spring 8 and connecting rod 3 bottoms are provided with certain clearance, and when operator's compartment 1 load less (being under the normal circumstances), the main spring 7 that length increases can work separately, realizes little rigidity requirement; When big or operator's compartment 1 was excessive with respect to the vertical vibration displacement of vehicle frame when operator's compartment 1 load, main spring 7 worked simultaneously with auxiliary spring 8, thereby realizes adaptively changing rigidity, and it both can increase load-carrying capacity, also can change the operator's compartment resonance frequency, effectively reduced vibration.Thereby the low rigidity that suspends before realizing under satisfying the situation of requirement of strength obtains preferable anti-vibration performance, improves traveling comfort and the safety taken.
In the present embodiment, the front end of connecting rod 3 is hinged with operator's compartment 1 front bottom end by first attaching parts 2, and connecting rod 3 is hinged with chassis side rail 5 tops by second attaching parts 4 near place, its rear end, and first attaching parts 2 and second attaching parts 4 are hinge.Connecting rod 3 is provided with a waist shaped hole 31, and the length direction of waist shaped hole 31 is identical with the car body longitudinal direction.Main spring 7 comprises main spring 71, pilot bar 72 and spring stop 73, the lower end of pilot bar 72 is installed in chassis side rail 5 bottoms one side by carriage 10, the upper end of pilot bar 72 is arranged in the waist shaped hole 31, main spring 71 is sheathed on the pilot bar 72, the bottom of main spring 71 is connected with carriage 10, and the top of main spring 71 contacts with the bottom of connecting rod 3 by spring stop 73.Because main spring 71 is longer, it is sheathed on and just can is unlikely to be bent when stand under load on the pilot bar 72 and reduces stability.Waist shaped hole 31 is set on the connecting rod 3, in the time of can preventing that connecting rod 3 from spinning upside down and pilot bar 72 interfere mutually.
In the present embodiment, the structure of two groups of auxiliary springs 8 is identical with type of attachment, but concrete size can be the same or different.Two groups of auxiliary springs 8 are divided into the both sides of second attaching parts 4.Auxiliary spring 8 comprises auxiliary spring 82 and guidance set, this guidance set comprises rubber block 81 and auxiliary spring pilot bar 83, auxiliary spring pilot bar 83 is fixed on chassis side rail 5 top airfoils, rubber block 81 is fixed on the top of auxiliary spring pilot bar 83, auxiliary spring 82 is sheathed on the auxiliary spring pilot bar 83, wherein, the length of auxiliary spring pilot bar 83 is provided with certain clearance less than the length of auxiliary spring 82 between the top of auxiliary spring 82 and connecting rod 3 bottoms.Under normal circumstances (load comparatively hour), each auxiliary spring 8 do not participate in carrying, and the design that the rigidity that suspends before making is more traditional is lower, and loading strength remains unchanged; When operator's compartment 1 produces displacement with respect to vehicle frame owing to vertical vibration, connecting rod 3 is with cw or left-hand revolution certain angle, push down the not auxiliary spring 8 of homonymy, auxiliary spring 82, rubber block 81 and auxiliary spring pilot bar 83 are played a role successively, regulate resonance frequency with the rigidity that suspends before the adaptively changing, thereby reach the purpose of vibration damping.Wherein, 83 pairs of operator'ies compartment 1 of rubber block 81 and auxiliary spring pilot bar play upper and lower buffering and spacing effect.
Under normal circumstances, have only main spring 7 to bear the load of operator's compartment 1, the rigidity that suspends before the operator's compartment 1 is less.When operator's compartment 1 front end reached certain displacement away from vehicle frame, connecting rod 3 clickwise certain angles were pushed down the auxiliary spring 82 of the auxiliary spring 8 that is arranged in second attaching parts, 4 rear ends, and the global stiffness that suspends before making increases; When operator's compartment 1 front end continues to reach certain displacement away from vehicle frame, connecting rod 3 will be pushed down rubber block 81, and limited because of the deflection of rubber block 81, so rubber block 81 and auxiliary spring pilot bar 83 play the effect of operator's compartment 1 upper limit buffering jointly.Otherwise when operator's compartment 1 front end reached certain displacement near vehicle frame, connecting rod 3 left-hand revolution certain angles were pushed down the auxiliary spring 82 of the auxiliary spring 8 that is arranged in second attaching parts, 4 front ends, and the preceding global stiffness that suspends increases; When the continuation of operator's compartment 1 front end reaches certain displacement near vehicle frame, connecting rod 3 will be pushed down rubber block 81, play the effect of operator's compartment 1 lower limit buffering.Can realize that the rigidity that suspends before the adaptively changing regulates resonance frequency, reach the purpose of effective vibration damping.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite all should be considered as protection domain of the present utility model.
