履带式东方红—60、75和802型拖拉机都采用弹性悬架。悬架用以连接支重轮和拖拉机机体,机体的重量全部经悬架传递给支重轮;同时,履带和支重轮在行驶中所受的冲击也通过悬架传到机体上。因此,履带式拖拉机若在地形复杂的条件下作业,由于地面不平、障碍过多、车速过快和操作不当等原因极易造成悬架弹簧和支重轮内、外平衡臂的断裂。而拆装悬架弹簧和支重轮内、外平衡臂是一项十分困难的工作。为方便拆装
Crawler Dongfanghong -60, 75 and 802 tractors are used flexible suspension. Suspension to connect the roller and tractor body, the body weight of all through the suspension to the roller; the same time, crawler and roller wheel in the impact suffered by the transmission to the body through the suspension. Therefore, if the crawler tractor operates under the complicated terrain, the breakage of the suspension spring and the inner and outer balance arms of the support roller can easily occur due to the uneven ground, excessive obstacles, excessive speed, improper operation and the like. And disassembly suspension springs and roller, the outer balance arm is a very difficult task. For easy disassembly
