The invention discloses a split type liquid rubber composite joint with a low diameter-axial ratio and an adjusting method, the split type liquid rubber composite joint comprises a core shaft, a rubber body, vulcanizing body outer sleeves, a stop block and an integral outer sleeve, the vulcanizing body outer sleeves are split type outer sleeves, a gap is formed between every two adjacent vulcanizing body outer sleeves, the rubber body is vulcanized between the vulcanizing body outer sleeves and the core shaft, a gap between the vulcanizing body outer sleeves extends into the rubber body; a hydraulic cavity with an opening in the outer side is defined by the mandrel, the rubber body and the vulcanizing body outer sleeve, a stop block is arranged in the hydraulic cavity and covers the vulcanizing body outer sleeve, and the outer sides of the stop block and the vulcanizing body outer sleeve are sleeved with an integral outer sleeve. The mandrel is provided with a concave pit which is concave towards the inner side of the mandrel, bosses are arranged on the two sides of the concave pit, the inner side of the stopping block is embedded in the concave pit of the mandrel, and when the stopping block and the mandrel move relatively in the axial direction, the bosses of the mandrel can stop the axial movement of the stopping block. Abrasion of a wheel track can be reduced, meanwhile, large axial rigidity is provided, and the running stability of a vehicle is guaranteed.
一种低径轴比的分瓣式液体橡胶复合节点及调节方法,芯轴、橡胶体、硫化体外套、止挡块和整体外套,硫化体外套为分瓣式的外套,相邻的两个硫化体外套之间设置有间隙,橡胶体硫化在硫化体外套与芯轴之间,且所述硫化体外套之间的间隙延伸到橡胶体中;芯轴、橡胶体和硫化体外套一起围成有一个外侧开口的液压腔,液压腔中设置有止挡块,止挡块盖合在硫化体外套上,在止挡块和硫化体外套的外侧套有整体外套;芯轴上开有向芯轴内侧凹陷的凹坑,凹坑的两侧都设置有凸台,止挡块内侧嵌在芯轴的凹坑中,当止挡块与芯轴发生轴向方向的相对移动时,芯轴的凸台能阻挡止挡块的轴向移动。能减小轮轨道的磨耗,同时提供较大的轴向刚度,确保车辆运行的稳定性。
