Fig. 2 is a partially enlarged schematic view of fig. 1.
Fig. 3 is a schematic view of the connection between the screw head section and the bushing bracket of the present invention.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings:
referring to fig. 1 and 2, the compact automobile control arm assembly of the present embodiment includes two bushing assemblies, where the inverted U-shaped arm body 1 is respectively disposed at two ends of the arm body 1, the bushing assemblies include a bushing bracket 2, a rubber bushing 3 having an inner tube, a bolt, and a nut 7, and the bushing bracket 2 has two side walls with bracket holes. The bolt comprises a screw head section 4, a screw thread section 5 and a blocking section 6 axially extending from the tail end of the screw thread section 5, wherein the radius of the blocking section 6 is smaller than that of the screw thread section 5. The bolt sequentially penetrates through a bracket hole of one side wall, the inner pipe of the rubber bushing 3 and a bracket hole of the other side wall and is in threaded connection with a nut 7 through a threaded section 5; the blocking section 6 is provided with an axial hole passage 8, the peripheral wall of the blocking section 6 is provided with two radial hole passages 9 communicated with the axial hole passage 8, and the radial section of the axial hole passage 8 is rectangular.
The end part of the blocking section 6 is provided with a blocking seat 10, the blocking seat 10 is provided with a V-shaped blocking elastic sheet 11 for blocking the nut 7 from falling off, the blocking elastic sheet 11 extends into the axial hole 8 and is provided with two elastic arms, two ends of each elastic arm respectively protrude outwards to form a blocking head 12, and the blocking heads 12 extend out of the radial hole 9.
