Embodiment
If Fig. 1 is the schematic diagram that the upper and lower two ends of extruding skewed slot of the present invention are separately fixed at top outside threaded holes and bottom outside threaded holes, Fig. 2 is the schematic diagram that the upper and lower two ends of extruding skewed slot of the present invention are separately fixed at top outside threaded holes and bottom outside threaded holes, a kind of low noise rolling friction vibration damper, comprise damping top board 1, spring 2, damping base plate 3, extruding skewed slot 4, damping cylinder 5 and buffering spacer 7, big roller 52 and trundle 53, damping top board 1 is fixedly connected with damping base plate 3 by extruding skewed slot 4, damping cylinder 5 is placed among extruding skewed slot 4, damping cylinder 5 both sides are respectively equipped with big roller 52 and trundle 53, damping top board 1 bottom is provided with buffering spacer 7, spring about 2 two ends are connected with damping base plate 3 with damping top board 1 respectively, damping top board 1 two ends are respectively equipped with top interior threaded hole 11 and top outside threaded holes 12, damping base plate 3 two ends are respectively equipped with bottom interior threaded hole 31 and bottom outside threaded holes 32, the skew wall upper end of extruding skewed slot 4 is provided with upper mounted plate 41, lower end is provided with bottom plate 42, upper mounted plate 41 is screwed into top interior threaded hole 11 by clamping bolt 6, bottom plate 42 is screwed into bottom interior threaded hole 31 by clamping bolt 6 and realizes being fixedly connected with of extruding skewed slot 4 and damping top board 1 and damping base plate 3, or upper mounted plate 41 is screwed into top outside threaded holes 12 by clamping bolt 6, bottom plate 42 is screwed into bottom outside threaded holes 32 by clamping bolt 6 and realizes being fixedly connected with of extruding skewed slot 4 and damping top board 1 and damping base plate 3, two big rollers 52 are fixedly connected with by fixing rod 51, two trundles 53 are fixedly connected with by fixing rod 51.
Big roller 52 on described damping cylinder 5 and trundle 53 carry out scroll-up/down along the skew wall extruding skewed slot 4, and diminish along with the distance extruded from bottom to top between skewed slot 4, big roller 52 and the extruding force suffered by trundle 53 become large gradually, and the resistance that damping cylinder 5 is subject to is also increasing, thus the big roller 52 of damping cylinder 5 both sides and the extruding of trundle 53 can be utilized, realize damping operation.Owing to being rolling friction, damping cylinder 5 moves up and down in process and can be good at reducing noise.When extruding skewed slot 4 is screwed in top outside threaded holes 12 and bottom outside threaded holes 32 by clamping bolt 6, the spacing of extruding skewed slot 4 and damping cylinder 5 can be increased, thus increase the stroke of damping.When extruding skewed slot 4 is screwed in top interior threaded hole 11 and bottom interior threaded hole 31 by clamping bolt 6, the spacing of extruding skewed slot 4 and damping cylinder 5 can be reduced, thus reduce the stroke of damping.Such two kinds of mounting types can change damping cylinder 5 and to move up and down rolling resistance, thus change damper stiffness and damping, meet the different vehicle required.
