mechanical engineering. SUBSTANCE: invention relates to fastening of turnable levers. Proposed bracket has cheek with cylindrical bosses provided with central holes, and lug with hole designed for mounting automobile suspension member. Central holes of bosses are provided with mated surfaces of cylinder and truncated cone. Hole of lug designed for mounting automobile suspension members is provided with chamfer at one side and rounding at back end side of lug for fitting rubber bushing into lug hole. Rubber bushing at its end faces has coaxially arranged cone and cylinder for providing elastic liability of rubber bushing under axial load from 1.5 to 2.5 tf. Rubber mixture used for manufacture of bushing of preserves its strength at temperatures from -25 C to + 175 C. Material of bracket provides integrity of automobile body and threaded joint members fitted in central holes of bosses at impact rupture of bracket. EFFECT: improved reliability. 3 dwg
