Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, in an embodiment of the present invention, a triangular arm structure for an automobile includes a triangular arm body formed by connecting a first arm 1, a second arm 2 and a third arm 3, a ball pin assembly 4 disposed at a free end of the first arm 1, a small bushing 6 disposed at a free end of the second arm 2, and a large bushing 5 disposed at a free end of the third arm 3, wherein a waist-shaped through hole 9 is formed at a middle portion of the triangular arm body, and the waist-shaped through hole 9 is disposed to reduce a weight of the triangular arm body as much as possible to achieve a lighter weight while ensuring a structural strength of the triangular arm body, and a reinforcing plate is added to both side surfaces of the triangular arm body in combination with the waist-shaped through hole 9, so that a strength at the middle portion of the triangular arm body can be increased to improve an overall strength performance of the triangular arm, therefore, the service life of the automobile triangular arm is effectively prolonged.

Reinforcing plates A8 and reinforcing plates B13 are respectively arranged on two side faces of the triangular arm body, the reinforcing plates A8 and B13 are the same in size, the projections of the reinforcing plates A8 and B13 relative to the surface of the triangular arm body are overlapped, a layer of rubber pad 10 is compositely connected to one side face of the reinforcing plate A8 and one side face of the reinforcing plate B13 facing the triangular arm body, the two ends of the reinforcing plate A8 and the reinforcing plate B13 and the surface of the triangular arm body are provided with coaxial mounting holes and fixedly connected to the triangular arm body through positioning bolts 7, the rubber pads 10 on the opposite surfaces of the reinforcing plate A8 and the reinforcing plate B13 are tightly attached to the corresponding surfaces of the triangular arm body, the rubber pads 10 can prevent the reinforcing plate A8 and the reinforcing plate B13 from contacting the triangular arm body to wear, the service life of the triangular arm body is prolonged by avoiding the wear of the triangular arm body, and the rubber pads 10 can be tightly attached to the surface of the triangular, therefore, when the triangular arm body is stressed, force is uniformly transmitted to the reinforcing plate through the rubber pad 10, and the structural strength of the triangular arm body is improved.

The reinforcing plate A8 is formed with waist shape boss 11 that matches with waist shape perforation 9 towards the surface of waist shape perforation 9, and waist shape boss 11 runs through into waist shape boss 11, through running through waist shape boss 11 in waist shape perforation 9 and thus play a positioning role, when the reinforcing plate produces little relative movement with the triangle arm body when bearing the force, the outer surface of waist shape boss 11 contacts the inner peripheral surface of waist shape perforation 9 and thus can transmit away a part of component force, simultaneously the outer peripheral surface of waist shape boss 11 wraps up round buffering gum cover 12 and hugs closely in the inner peripheral surface of waist shape perforation 9, thereby play the cushioning effect between waist shape boss 11 and waist shape perforation 9, in order to reduce the wearing and tearing between the two.

The buffer rubber sleeve 12 is of a hollow structure, an inner interlayer is formed in the buffer rubber sleeve 12, a plurality of small rubber balls 14 are filled in the inner interlayer, the impact force is offset by extrusion deformation generated when the small rubber balls 14 receive bearing force, and then the waist-shaped boss 11 can better transmit the bearing force to the triangular arm body.
