Anti-abrasion automobile steering device

By employing a dual reinforcement mechanism—combining the limiting plate with the limiting groove, the sealing gasket being tightly attached, and the external arc-shaped plate being snapped in—the problem of the leak-proof bellows in traditional automotive steering systems loosening due to vibration and temperature changes is solved, resulting in a more stable seal and a longer service life.

AI Technical Summary

Technical Problem

In traditional automotive steering systems, the method of fixing the leak-proof bellows is prone to loosening due to vibration, impact, or temperature changes in complex road environments and long-term use, resulting in a significant reduction in the leak-proof effect.

Method used

The design employs a locking structure where the limiting plate on the inner side of the fixed sleeve plate engages with the limiting groove on the outer ring plate. Combined with the tight-fitting design of the sealing gasket on the inner wall of the irregular groove, the locking of the outer arc plate with the fixed groove, and the threaded connection of the auxiliary plate and the fixing bolts, a double reinforcement mechanism is formed to ensure the stability of the leak-proof corrugated pipe in both horizontal and vertical directions.

Benefits of technology

It significantly improves the fixing stability of the leak-proof corrugated pipe, enhances the sealing effect, resists loosening caused by vibration and temperature changes, extends the service life, and improves the durability of the structure.

Abstract

The utility model discloses an anti-abrasion automobile steering gear which comprises a main body, steering pull rods are fixedly assembled on the two sides of the main body respectively, leakage-proof corrugated pipes are arranged on the outer sides of the steering pull rods in a sleeved mode, one side of each leakage-proof corrugated pipe and the side face of the main body are fixedly installed, and outer annular plates are fixedly connected to the two ends of the outer side of the main body respectively. And a fixed sleeve plate is arranged on the outer side of one end of the leakage-proof corrugated pipe. According to the anti-abrasion automobile steering device, through a clamping structure between a limiting plate on the inner side of the fixing sleeve plate and a limiting groove in the outer annular plate, one end of the anti-leakage corrugated pipe is stably fixed in the horizontal direction, horizontal displacement generated by vibration and impact in the automobile running process is effectively resisted through the design, and the fixing stability is remarkably improved; due to the design that the sealing gasket fixedly connected with the inner wall of the irregular groove is tightly attached to the outer surface of the leakage-proof corrugated pipe, a reliable sealing interface is formed, oil liquid is effectively prevented from leaking from the fixed position, and the leakage-proof effect is further enhanced.
