Common faults |
Fault Analysis |
Improvement scheme of thrust rod |
| 1 |
The rubber of the rubber ball pin is peeled off from the ball pin, the metal ball pin rotates and the rubber is extruded. |
The adhesion is not up to standard, or the selected adhesive and compound are unreasonable. |
Adopt Chemlok hot-vulcanized adhesive, which greatly improves the adhesion between rubber and ball pin. |
| 2 |
The rubber of the rubber ball pin is damaged, serious cracks appear on the surface, and a deep gap appears between the rubber and the ball pin framework. |
The surface of the ball pin is scratched by foreign matters, or the rubber is naturally aged and cracked. |
The rubber core adopts natural rubber, which has better elasticity and fatigue resistance. |
| 3 |
The thrust rod is bent and deformed or the rod body is broken. |
The stress of the stress bar is too large or fatigue crack occurs, and fracture occurs during use; The ball pin link bolt is loose or the support is broken, resulting in the bending or fracture of the thrust rod; The thrust rod is bent or broken under the action of external objects or external forces. |
The load-bearing rod adopts thickened and thickened (from 50 to 54 and 60) high-quality seamless steel pipe, which greatly improves the service life compared with ordinary load-bearing rod. |
| 4 |
The ball pin handle of the thrust rod is broken. |
The handle is torn due to loose fixing bolts; The fatigue crack or quenching and tempering crack of the ball pin hole causes the fracture of the handle in use. |
The ball pin handle of thrust rod is quenched and tempered with 40Cr material, with high comprehensive mechanical performance and high fatigue resistance. |
| 5 |
The distance between the left and right rear axles of the vehicle is inconsistent, resulting in accelerated tire wear. |
The center distance between the left and right lower thrust rods is inconsistent, or the clearance is too large due to the wear of the ball pin rubber on one side. |
The products are produced by the machining center, which guarantees 100% pass rate of the concentricity and center distance of each thrust rod. |
| 6 |
Abnormal noise on the rear axle of the vehicle. |
The thrust rod is damaged or the rubber of the ball pin is worn, and the ball pin comes out. |
