Detailed description of the invention
In conjunction with accompanying drawing 1, accompanying drawing 2, a kind of variation rigidity trailing arm independent suspension, it is mainly made up of fork-shaped trailing arm 1, vertical damper 12 and variation rigidity elastic device.
Fork-shaped trailing arm 1 left end is horizontal fork configuration, pitch end machining at two and have horizontal circular hole, two circular holes are connected with loader frame or car body by bearing pin, fork-shaped trailing arm 1 right-hand member is horizontal platy structure, heart position vertical direction processing wherein has circular hole, in horizontal cylindrical structure in the middle part of fork-shaped trailing arm 1, and it is connected with wheel of loading machine, cross shaft joint and power transmission shaft by this part.
Vertical damper 12 adopts hydraulic buffer, and its lower end is connected with fork-shaped trailing arm 1, and its upper end is connected with loader car body.
Variation rigidity elastic device is mainly made up of stiffness reliability oil cylinder 3, voussoir 4, bearing pin 5, roller the 6, first varying pitch spring 7, T-shaped pull bar the 8, second varying pitch spring 9, branch sleeve 10, gland 11. stiffness reliability oil cylinder 3 is arranged on fork-shaped trailing arm 1 right-hand member lower surface, piston 2 is installed in it, piston 2 right-hand member is connected with voussoir 4 left end by piston rod, voussoir 4 is arranged on fork-shaped trailing arm 1 right-hand member lower surface by chute, and can move left and right along chute, voussoir 4 lower surface is stepped plane, stairstepping interplanar is excessive with inclined-plane, the processing of T-shaped pull bar 8 lower end has groove, and it is placed in the vertical hole of fork-shaped trailing arm 1 right-hand member, the direction processing perpendicular with groove in T-shaped pull bar 8 lower end has through hole, bearing pin 5 is installed in through hole, roller 6 is arranged on bearing pin 5, it is placed in the groove of T-shaped pull bar 8 lower end, voussoir 4 is placed in the groove of T-shaped pull bar 8 lower end, voussoir 4 lower surface contacts with roller 6, on T-shaped pull bar 8, T-shaped emits between fork-shaped trailing arm 1 right-hand member upper surface, it is sequentially installed with the second varying pitch spring 9 from top to bottom, branch sleeve 10, first varying pitch spring 7, branch sleeve 10 is cup-shaped, bottom it, processing has circular hole, branch sleeve 10 is arranged on T-shaped pull bar 8 by this circular hole, it is connected to gland 11 in branch sleeve 10 upper end, gland 11 is connected with loader car body or vehicle frame.
The stiffness variation process of variation rigidity elastic device is: the hydraulic oil provided by loader hydraulic system enters on the left of stiffness reliability oil cylinder 3 inner carrier 2, and push piston 2 moves to right, piston 2 pushes away voussoir 4 further through piston rod and moves to right, thus by downward for roller 6 jack-up, now roller 6 and the high end contact of voussoir 4; Roller 6 drives T-shaped pull bar 8 to move down by bearing pin 5, thus the first varying pitch spring 7 and the second varying pitch spring 9 are compressed, now, variation rigidity elastic device rigidity becomes big, when loader hydraulic system hydraulic oil enters on the right side of stiffness reliability oil cylinder 3 inner carrier 2, and push piston 2 moves to left, piston 2 pulls voussoir 4 to move to left by piston rod, now roller 6 and the low end contact of voussoir 4, T-shaped pull bar 8 under the tension force effect of the first varying pitch spring 7 and the second varying pitch spring 9 on move, this time-varying rigidity elastic device rigidity diminishes.
