Abstract
The invention discloses a bushing for an automotive trailing arm. The bushing for the automotive trailing arm comprises an outer pipe and an inner pipe, wherein the inner pipe is arranged in the outer pipe. The bushing for the automotive trailing arm is characterized in that two mounting bases used for mounting the inner pipe is arranged in the outer pipe; the two mounting bases are symmetrically arranged in the outer pipe; outer side walls of the mounting bases are connected with the inner side wall of the outer pipe through rubber main springs in a vulcanization manner; the two mounting bases are enclosed and arranged to form an inner pipe mounting cavity; the inner pipe is inserted into the inner pipe mounting cavity; and further, the inner pipe is in tight fit with the two mounting bases respectively. The bushing for the automatic trailing arm has the advantages that the inner pipe is connected with the rubber main springs through assembly structures; as the rubber main springs have elasticity, at this moment, the different pre-compression amounts of the rubber main springs under the same structures of the rubber main springs can be realized through regulating the size of the structure of the inner pipe, so as to realize the maximum pre-compression amount of the rubber main springs; even though the pre-compression amounts of the rubber main springs are greater, in the condition that the rubber main springs are thick enough, the high enough radial rigidity of the bushing can be also guaranteed; and moreover, the fatigue properties of the bushing of the automotive trailing arm can be furthest improved.
