[0020] The technical scheme of the utility model will be described clearly and completely in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] In the description of the utility model, it is necessary to explain that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second" and "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. The utility model will be further described in detail below with reference to the drawings.

[0022] As shown in Figures 1-5 The utility model provides a novel automobile suspension arm support arm, including support arm 1 and mounting hole 2, mounting hole 2 is located on support arm 1, and mounting hole 2 is detachably installed with rubber sleeve 3, and the inner wall of mounting hole 2 is uniformly distributed with a plurality of clamping grooves 4 along the circumferential direction, the rubber sleeve 3 is provided with a clamping strip 5 on the outer side corresponding to the position of the clamping groove 4 of the support arm 1, and the cooperation of the clamping groove 4 and the clamping strip 5 preliminarily limits the rubber sleeve 3, and the limit structure 6 is arranged at the position close to the two ends of the mounting hole 2 on the support arm 1, for firmly limiting the two ends of the rubber sleeve 3 in the mounting hole 2.

[0023] As shown in Figure 2 , 4 The limit structure 6 includes a slot 7, the slot 7 is symmetrically arranged on the support arm 1 corresponding to the position of the clamping strip 5 and the clamping groove 4, and the slot 7 is staggered, to ensure the smoothness of the rubber sleeve installation, the slot 7 is horizontally fixed with a limiting shaft 8, the limiting shaft 8 is slidably provided with a stopper 9, the outer side of the stopper 9 is slidably arranged relative to the inner wall of the slot 7, and the limiting shaft 8 is provided with a spring 10 connected to the inner wall of the slot 7 and the outer side of the stopper 9, so as to facilitate the automatic reset of the stopper 9 and press-fit in the rubber sleeve 3.

[0024] As shown in Figure 4 The longitudinal section of the stopper 9 is L-shaped, and a finger groove 11 is embedded on the horizontal end of the stopper 9, so as to facilitate the manual adjustment of the position of the stopper 9 by the operator, and the rubber sleeve 3 is taken out, the stopper 9 is inclined to the mounting hole 2 on one side of the mounting hole 2, forming a wedge-shaped structure, and when the rubber sleeve 3 is installed, it is extruded by the rubber sleeve 3 and moves in the slot 7.
