A wear-resistant car steering gear

Abstract

This utility model discloses a wear-resistant automotive steering gear, comprising a main body, with steering tie rods fixedly mounted on both sides of the main body. A leak-proof bellows is sleeved on the outer side of each steering tie rod, with one side of the leak-proof bellows fixedly installed to the side of the main body. Outer annular plates are fixedly connected to both ends of the outer side of the main body, and a fixing sleeve is provided on the outer side of one end of the leak-proof bellows. This wear-resistant automotive steering gear achieves stable horizontal fixation of one end of the leak-proof bellows through a snap-fit ​​structure between the limiting plate on the inner side of the fixing sleeve and the limiting groove on the outer annular plate. This design effectively resists horizontal displacement caused by vibration and impact during vehicle operation, significantly improving fixation stability. The sealing gasket fixedly connected to the inner wall of the irregular groove and the tight fit design with the outer surface of the leak-proof bellows form a reliable sealing interface, effectively preventing oil leakage from the fixing point and further enhancing the leak-proof effect.

Description

Technical Field

[0001] This utility model relates to the field of automotive steering technology, specifically to a wear-resistant automotive steering system. Background Technology

[0002] A car steering gear is a common automotive component in a car's steering system. Its function is to assist the driver in applying force while turning the steering wheel, thereby reducing the effort required for steering and making driving easier and more convenient. Currently, the main types of car steering gears on the market are rack and pinion steering and worm gear steering.

[0003] In traditional automotive steering system designs, leak-proof bellows are mainly fixed to the steering tie rod or main body using simple clips or screws. This fixing method is prone to loosening due to vibration, impact, or temperature changes in complex and changing road environments and during long-term use, resulting in a significant reduction in the leak-proof effect. Utility Model Content

[0004] The purpose of this utility model is to provide a wear-resistant automotive steering gear to solve the problem mentioned in the background art that in the traditional automotive steering gear design, the anti-leakage bellows is mainly fixed to the steering tie rod or body by simple clips or screws. This fixing method is prone to loosening due to vibration, impact or temperature changes in complex and changing road environments and long-term use, resulting in a significant reduction in the anti-leakage effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant automotive steering gear, comprising a main body, with steering tie rods fixedly mounted on both sides of the main body, a leak-proof corrugated tube sleeved on the outer side of the steering tie rod, one side of the leak-proof corrugated tube being fixedly installed to the side of the main body, outer annular plates fixedly connected to both ends of the outer side of the main body, a fixing sleeve plate provided on the outer side of one end of the leak-proof corrugated tube, an irregular groove being formed near the center of the fixing sleeve plate, limiting grooves being formed at the top and bottom of the opposite ends of the two outer annular plates, limiting plates being fixedly connected to the top and bottom of the outer side of the fixing sleeve plate near the outer end, fixing grooves being formed at the top and bottom of the outer surface of the outer annular plate and the top and bottom of the outer surface of the fixing sleeve plate, and an outer arc plate one and an outer arc plate two being provided at the top and bottom of the outer side of the fixing sleeve plate.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This wear-resistant automotive steering gear achieves a stable horizontal fixation of one end of the leak-proof bellows through a snap-fit ​​structure between the limiting plate on the inner side of the fixed sleeve and the limiting groove on the outer ring plate. This design effectively resists horizontal displacement caused by vibration and impact during vehicle operation, significantly improving fixation stability. The sealing gasket fixed to the inner wall of the irregular groove and the tight fit design with the outer surface of the leak-proof bellows form a reliable sealing interface, effectively preventing oil leakage from the fixing point and further enhancing the leak-proof effect. The external arc plate one and external arc plate two, through the snap-fit ​​between the fixing block and the fixing groove, not only provide additional support for the fixation of the leak-proof bellows but also enhance the strength and rigidity of the overall structure. This design helps resist deformation and loosening during long-term use, extending service life. The auxiliary plate one and auxiliary plate two, through the snap-fit ​​between the slot and the plate and the threaded connection of the fixing bolt, achieve vertical tightening. This double reinforcement mechanism effectively prevents loosening caused by vibration and temperature changes, improving the durability of the structure. Attached Figure Description

The opposite sides of the two fixing blocks 12 pass through the interior of the two fixing grooves 10 and are engaged with the fixing grooves 10.

[0018] Auxiliary plate 14 and auxiliary plate 2 16 are fixedly connected to the outer ends of the opposite sides of the external arc plate 11 and external arc plate 2 13, respectively. A slot 15 is opened at the center of the bottom of auxiliary plate 14, and a card plate 17 is fixedly connected to the center of the top of auxiliary plate 2 16.

This design effectively resists horizontal displacement caused by vibration and impact during vehicle operation, significantly improving the fixation stability. The sealing gasket 7, fixedly connected to the inner wall of the irregular groove 6, and the tight-fitting design with the outer surface of the leak-proof bellows 3 form a reliable sealing interface, effectively preventing oil leakage from the fixing point and further enhancing the leak-proof effect. The external arc-shaped... Plate 11 and external arc-shaped plate 213 are connected to the fixing groove 10 by the fixing block 12, which not only provides additional support for fixing the leak-proof corrugated pipe 3, but also enhances the strength and rigidity of the overall structure. This design helps to resist deformation and loosening during long-term use and extends the service life. Auxiliary plate 14 and auxiliary plate 216 are connected to the clamping plate 17 by the clamping groove 15 and the threaded connection of the fixing bolt 18 to achieve vertical fastening. This double reinforcement mechanism effectively prevents loosening caused by vibration and temperature changes and improves the durability of the structure.
