Description

Automobile control arm assembly Technical Field The utility model relates to the technical field of automobile accessories, in particular to an automobile control arm assembly. Background The suspension is a generic name of a force transmission connecting device between an automobile wheel and an automobile body, the suspension comprises an elastic element, a shock absorber and a force transmission device, the force transmission device comprises a control arm, a pull rod, a stabilizer bar and the like, but the control arm assembly and an installed rubber sleeve are limited in the actual use process through a rubber sleeve boss, the limiting strength is insufficient, the rubber sleeve is connected with a connecting rod and then rotates through a screw sleeve of the connecting rod limited by an anti-slip part, the stability is insufficient, and the connection and the use safety are reduced. For example, an automobile control arm assembly is disclosed in bulletin number CN220594568U, and this automobile control arm assembly includes the arm body, is connected with bulb subassembly, gum cover subassembly and bush subassembly on the arm body, and gum cover subassembly includes inner tube, outer tube and elastomer, and the elastomer links firmly between inner tube and outer tube, and the length of inner tube is greater than the length of outer tube. According to the scheme disclosed by the above, the rubber sleeve component is connected with the arm body through the elastic body, and due to the fact that the elastic body is insufficient in extrusion resistance and impact strength, the elastic body is thinned under the action of the tensile force between the connecting rod and the arm body, the gap at the connecting position is enlarged, the rubber sleeve is separated, the service stability of the rubber sleeve is reduced, the rubber sleeve component prevents the screw sleeve on the surface of the connecting rod from automatically rotating through the first anti-slip teeth, the limiting effect is poor, the screw sleeve can automatically rotate or slip threads are loosened due to vibration force, and the connection safety of the connecting rod is reduced.
