The invention discloses an auxiliary frame bushing which comprises a metal inner cylinder and a rubber layer and further comprises a metal framework, the metal framework is arranged outside the metal inner cylinder, the outer surface of the metal framework and the rubber layer are vulcanized into a whole, and the rubber layer is used for being attached to an auxiliary frame. The metal inner cylinder is used for being connected with a mounting bolt through a nut. The invention further discloses an auxiliary frame assembly. The rubber layer and the auxiliary frame only need to be attached, so that disassembly and assembly are very convenient, when the auxiliary frame lining is damaged, only the lining needs to be replaced, the whole auxiliary frame assembly does not need to be replaced, and the maintenance cost is reduced. And moreover, during working, the rubber layer and the metal framework are not easy to crack, so that the service life of the bushing is prolonged.
本发明公开了一种副车架衬套,包括金属内筒和橡胶层,还包括金属骨架,所述金属骨架设置在所述金属内筒的外部,所述金属骨架的外表面与所述橡胶层硫化成一体,所述橡胶层用于与副车架贴合,所述金属内筒用于与安装螺栓通过螺母连接。本发明还公开了一种副车架总成。本发明中橡胶层与副车架仅需要贴合,因此拆装非常方便,当副车架衬套损坏时,只需要更换衬套即可,不需要将整个副车架总成更换,降低了维修成本。并且,在工作时,橡胶层与金属骨架之间也不易开裂,增加了衬套的使用寿命。
