Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
The wear-resisting stabilizer bushing of a kind of grinding tooth shape, including fixed support 1, bush body 2 and skeleton 3；
As shown in drawings, in the middle of the surface of described bush body 2, be provided with lining convex tendon 23, the edge of bush body 2 with
Being provided with lining engaging tooth 21 between convex tendon 23, the side of bush body 2 is provided with an otch being perpendicular to QS 4
22, described otch 22 is switched to lining endoporus 24 by bush body outer surface；Annular it is evenly arranged with recessed on described lining inner hole wall
Groove 241, described bush body 2 is embedded with skeleton 3, and bush body 2 is divided into outer rubber layer 25 and inner rubber layer by described skeleton 3
26 two parts, the thickness of described inner rubber layer 26 is more than the thickness of described outer rubber layer 25；
As in figure 2 it is shown, described fixed support 1 matches with the outer surface of described bush body 2, engaging with described lining
The position of tooth 21 engagement, the inner surface of described fixed support 1 is correspondingly provided with support engaging tooth 13, as it is shown in figure 1, described fixing
Support 1 is divided into upper and lower two parts, described top and the bottom seam to be provided with support flange 12, described support flange 12 by horizontal axis
Being provided with connection holes 11, two parts up and down of fixed support 1 are coupled and are connected and fixed with car body corresponding site by connection holes 11；
As it is shown in figure 1, described skeleton 3 is divided into skeleton 1 and skeleton 2 32, described skeleton 1 and described skeleton 2 32
Relatively being embedded in bush body 2, cross section is arc-shaped, and the two is not attached to, and seam has gap 35；As it is shown on figure 3, described bone
