Leaf spring grasswort vulcanizes bush

The utility model discloses a leaf spring grasswort vulcanizes bush, its characterized in that has interior sleeve pipe in inside interlude of outer tube it has the rubber layer to vulcanize in the inner wall of outer tube and the space between the interior sheathed tube outer wall. Through the setting, the utility model discloses a cross -section is sleeve pipe in oval, makes the long -pending increase of bearing surface on rubber layer, when outer tube and interior sleeve pipe push the rubber layer, has reduced the bearing pressure on rubber layer, and effective wearing and tearing that reduce the rubber layer make the rubber layer difficult damaged, have lengthened the utility model discloses a life. 本实用新型公开了种钢板弹簧卷耳硫化衬套，其特征在于，在外套管的内部穿插有内套管，在所述外套管的内壁与内套管的外壁之间的空隙内硫化有橡胶层。通过以上设置，本实用新型采用截面为椭圆形内套管，使橡胶层的承重面积增大，外套管和内套管对橡胶层进行挤压时，降低了橡胶层的承重压强，有效降低对橡胶层的磨损，使橡胶层不易破损，延长了本实用新型的使用寿命。
