The invention discloses a steering tie rod joint assembly with high sealing performance. The steering tie rod joint assembly comprises a ball pin, a dustproof cover, a dustproof cover clamping ring, a joint, a ball seat, an end cover and a hexagon slotted nut; the ball pin is composed of a ball body, a trapezoidal platform and a cone, the ball body is arranged at the lower part of the ball pin, the trapezoidal platform is shaped like an inverted trapezoid, and a cylindrical step is arranged between the large end of the trapezoidal platform and the large end of the cone at the lower part of the cone and is in circular arc transition with the cone; the upper end of the dustproof cover is mounted on the cone of the ball pin, the lower end of the dustproof cover is mounted on an annular boss at the upper end of the joint, and a clamping slot in the lower end of the dustproof cover is internally provided with the dustproof cover clamping ring; and the cover body at the upper part of the dustproof cover is internally provided with an L-shaped framework, and the upper end surface of the dustproof cover is also provided with a convex edge of a triangular section. According to the technical scheme of the invention, defects in the prior art are overcome, the steering tie rod joint assembly is safe, reliable and good in dustproof and sealing performances, the defect of poor sealing performance of the dustproof cover in swing and rotation processes under the condition that the ball pin is relatively long is overcome, and the service life of the steering tie rod joint assembly is prolonged.
Description
technical field [0001] The invention relates to the technical field of auto parts, and is suitable for joint assemblies at both ends of steering rods and straight rods of various automobiles, in particular to a steering rod joint assembly with high sealing performance. Background technique [0002] As an important part of the automobile chassis, the automobile tie rod joint assembly directly affects the service life of the vehicle and driving safety. In order to ensure the service life and safety of the joint assembly, the quality of the sealing is very important to the joint assembly. In addition, due to the chassis space, the ball pin design of the joint assembly of some horizontal and straight rods is longer, and the height of the dust cover is also increased accordingly. However, such a dust cover structure cannot provide good elastic support. After the ball pin swings and rotates greatly, the upper part of the dust cover is easy to sink, which will aggravate the wear o...
