Embodiment Construction

[0008] Such as figure 2 As shown, the bushing inner ring 1 has a rubber ring 2 with an "I"-shaped cross-section on the sleeve shaft, and a rubber deformation groove 4 is provided between the inner bottom of the "I"-shaped convex edge at one end of the rubber ring and the side end of the rubber ring. The notch width of the rubber deformation groove is larger than the groove bottom width, and the section of the rubber deformation groove is "V" shape. The direction of the "V" type rubber deformation groove is not perpendicular to the axis. The angle between the direction of the "V"-shaped rubber deformation groove and the axis is an acute angle, so that the "V"-shaped rubber deformation groove is in the same extrusion deformation direction as the "I"-shaped convex edge, which is beneficial to the "I"-shaped rubber ring " Extrusion deformation and elastic reset of "I"-shaped convex edge.

[0009] The shaft section of the outer ring 3 of the bushing is "T" type and is set on the...

Abstract

The invention discloses a suspension system triangle arm rubber lining with bidirectional position limiting, comprising a lining internal ring, a rubber ring and a lining external ring; the section of the shaft of the rubber ring is a horizontal-H-shape; the section of the shaft of the lining external ring is a T-shape; a rubber deformation channel is arranged between the bottom of the internal side of the horizontal-H-shaped convex edge at one end of the rubber ring and the end of the side surface of the rubber ring. During the installation process, the horizontal-H-shaped convex edge is extruded into the rubber deformation channel so as to lead the convex external edge to be aligned to the side surface of the rubber ring, thus passing through the triangle arm hole; after the installation position is reached and the initial shape is recovered due to the elastic deformation of the rubber, a convex platform of the rubber part is formed, thus achieving the object of bidirectional position limiting; the triangle arm rubber lining has smart concept and simple structure, realizes the bidirectional position limiting on the triangle arm hole by using one part, reduces the quantity of the parts and the installation procedures by unidirectional installation, and greatly lowers the cost for production, manufacture and installation by 20-30 percent.

Description

technical field [0001] The invention belongs to auto parts, in particular to a rubber bushing for a triangular arm of a suspension system. Background technique [0002] There are currently two structural forms of the front hinge of the triangular arm of the car suspension system. One is that the "T" rubber bush is installed on the triangular arm. The interference fit between the outer ring of the bush and the hole of the triangular arm realizes the fixation of the rubber bush, which brings great difficulties to the installation of the rubber bush. The other is to install two "T" rubber bushes opposite to each other to form a two-way limit (such as figure 1 ), in fact, this so-called two-way limit is actually a one-way limit. The rubber bush on the left is limited to the right, but there is no limit to the left. There is no limit. At the same time, two parts are used here, the cost of the parts is high, and two-way installation is required during simultaneous installation,...
