Embodiment
Embodiment describes in further detail model utility below in conjunction with accompanying drawing.
Fig. 1 to Fig. 3 shows mode of execution of a kind of split type resilient bushing of the present utility model.Split type resilient bushing is combined integrated by elastic sleeve 11, plastics spacer 12 and plastic bushing 13 threes.
Outer diameter configuration one plastic bushing 13 of the coupling shaft 5 of automotive suspension, the two ends, the left and right sides of the external diameter of plastic bushing 13 respectively dispose a plastics spacer 12, outer diameter configuration one elastic sleeve 11 of plastics spacer 12, elastic sleeve 11 devices are in the swing arm supporting trepanning 6 of suspension.Swing arm supporting sleeve 6 is fixedlyed connected with suspension swing arm parts 3, referring to shown in Figure 1.
The external diameter of plastics spacer 12 and the internal diameter of elastic sleeve 11 are set to interference fit in the suspension swing arm assembling; Plastic bushing 13 is set to interference fit with coupling shaft 5; As shown in Figure 2.Plastics spacer 12 relatively rotates with plastic bushing 13 in swing arm moves up and down process, and the external diameter of plastic bushing 13 is provided with four vertical oil storage tanks, and spacer 12 and plastic bushing 13 are turned round having under the sufficient lubricating condition.And do not twist by the elastic sleeve 11 of rubber body material.
