Problems solved by technology

[0002] When the ball pin of the steering outer tie rod moves to the extreme corner condition, or when the outer tie rod shield is touched when the steering tie rod is disassembled on the vehicle, the outer tie rod shield is easily compressed to the bottom of the tie rod, and the air in the shield is Squeeze out to form a negative pressure, resulting in irreversible deformation (with corresponding TIR), resulting in the exposed part of the ball pin journal of the outer tie rod being corroded and rusted, shortening the service life of the tie rod, and reducing the customer's perceived quality of the product

Embodiment Construction

[0016] Such as figure 1 -5, the present invention discloses a steering outer tie rod ball pin device, including an outer tie rod 1, a dust cover 2, the outer tie rod 1 is provided with an outer tie rod journal 3, the outer tie rod journal 3 is provided with There is a slot 4, and the dust cover 2 is installed at the position of the outer tie rod journal 3. When the protective cover 2 is compressed and deformed, air enters the dust cover 2 through the slot 4.

[0017] The number of the notches 4 is multiple, and the plurality of notches 4 are evenly distributed in the circumferential direction at the cylinder of the outer tie rod journal 3.

[0018] The groove depth of the notch 4 is 0.5 mm, and the groove width is 1 mm.

[0019] The number of the slot 4 is three.

[0020] The outer tie rod 1 also includes a threaded rod 5 connected with the outer tie rod journal 3.

[0021] The outer steering rod ball pin device of the present invention further includes a steering knuckle 6 mounted on ...

Abstract

The invention provides a turning outer pull rod ball pin device. The device comprises an outer pull rod and a dustproof cover, the outer pull rod is provided with an outer pull rod shaft neck, grooveopenings are formed in the outer pull rod shaft neck, the dustproof cover is arranged at the outer pull rod shaft neck, when the dustproof cover is compressed and deformed, air enters the dustproof cover through the groove openings. The device has the beneficial effects that the problem of unrecoverable deformation of the turning outer pull rod dust cover under excessive extrusion is solved, the outer pull rod ball pin is prevented from being exposed and rusted, the service life of the part is prolonged, and the customer perception quality is improved.

Description

Technical field [0001] The invention relates to the technical field of automobile chassis, in particular to a steering outer tie rod ball pin device. Background technique [0002] When the steering outer tie rod ball pin moves to the extreme cornering condition, or the outer tie rod shield is touched when the steering rod is disassembled on the whole vehicle, the outer tie rod shield is easily compressed to the bottom end of the tie rod, and the air in the shield is Extrusion to form negative pressure, resulting in irreversible deformation (with corresponding TIR), causing the outer tie rod ball pin journal part to be exposed and corroded and rusted, shortening the service life of the tie rod, and reducing customer perception of product quality. Summary of the invention [0003] The invention provides a steering outer tie rod ball pin device, comprising an outer tie rod and a dust cover, the outer tie rod is provided with an outer tie rod journal, the outer tie rod journal is prov...
