Description

Technical Field

[0001] The utility model relates to the technical field of steering machine sealing, in particular to a dustproof and waterproof enhanced steering machine. Background Art

[0002] The steering gear is an important part of the car, mainly responsible for converting the driver's directional input so that the vehicle can turn smoothly. Its functions involve the following aspects: First, the steering gear allows the driver to change the direction of the vehicle by turning the steering wheel. This is achieved through a mechanical connection with the wheel system, allowing the driver to easily control the steering behavior of the vehicle. The design and performance of the steering gear have an important impact on the driving experience and vehicle handling. Secondly, the steering gear usually includes some auxiliary functions, such as the electric power steering system. These systems use motors to assist steering, making control easier and more flexible, especially when driving at low speeds or parking. The electric power steering system can be intelligently adjusted according to vehicle speed and driving conditions to improve the convenience of control. Third, the steering gear also has safety functions, such as the coordinated work of the anti-lock braking system (ABS) and the vehicle stability control system (ESP). This helps prevent the vehicle from losing control in emergency braking or extreme handling situations and improves driving safety. In order to protect the normal operation of the steering gear, dust boots are designed and set at key parts of the steering gear. The functions of the dust boots are mainly reflected in the following aspects: First, the dust boots effectively prevent dust, sand, moisture and other impurities from entering the interior of the steering gear. This helps prevent corrosion and damage to the mechanical parts of the steering gear by external substances such as rain and dust, thus extending the service life of the steering gear. Secondly, the dust cover reduces friction and wear, protecting the key parts of the steering gear. During driving, the dust cover isolates the external environment from the moving parts inside the steering gear, reduces friction between parts, and thus slows down the wear rate of parts.

[0003] Traditional dust boots play a key protective role in vehicle steering gears. However, due to their specific materials and designs, they are prone to cracking, which leads to the entry of internal dust and moisture, and eventually causes rust and damage to the steering gear. One of the main reasons for this problem is that traditional dust boots are usually made of rubber or rubber mixed materials. Although rubber has certain elasticity and sealing properties, it is also susceptible to aging and deterioration due to the influence of the external environment, making the dust boots fragile. Under the influence of long-term use and harsh environments, rubber dust boots are prone to cracking, thus losing their original sealing effect. When the dust boots are broken, dust, particles and moisture in the air can easily penetrate into the interior of the steering gear. These impurities will mix with the lubricating oil to form dirt, which will eventually cause corrosion and rust of the internal parts of the steering gear. Rust will increase the friction of the parts, reduce the flexibility of control, and damage the normal operation of the steering gear. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1The dustproof and waterproof enhanced steering gear comprises a dust cover assembly 1. The dust cover assembly 1 is the core part of the design. Its composite structure and carefully selected materials give the steering gear excellent anti-aging performance. The dust cover assembly 1 has a head, a middle part and a tail part. A funnel-shaped channel 14 is designed on the inner side of the head. A guide baffle 141 is provided at the end of the channel 14 to prevent water mist from directly contacting the metal material in a humid environment. The funnel-shaped channel 14 is cleverly designed on the inner side of the head. This design functionally achieves the dual effects of guiding and preventing external harmful substances. The design of the funnel-shaped channel 14 enables the steering gear to more effectively resist the invasion of harmful substances such as external dust and moisture. , which improves the protection effect and provides a strong guarantee for the maintenance of the steering gear 2; the guide baffle 141 arranged at the end of the channel 14 further enhances the protection effect in a humid environment, and the water mist is guided to the bottom of the metal material, effectively preventing the water mist from directly contacting the metal material, thereby avoiding the potential harm of the humid environment to the steering gear; the middle part is designed as a double-layer structure with an interlayer, and the interlayer is filled with a non-Newtonian fluid 13, which is made of polyacrylamide or polyethylene oxide, and rheological agents and thickeners are also added therein. The introduction of the non-Newtonian fluid has important viscosity and rheological properties, so that it forms a stable damping effect during movement. This not only effectively reduces the friction of the dust cover and prolongs its service life, but also has the characteristics of high temperature resistance and anti-aging, further improving the durability and reliability of the steering machine; and the middle part is a flexible and retractable material, which is specifically made of propylene rubber, nitrile rubber or fluororubber with elasticity and sealing performance and has a corrugated appearance, providing the steering machine with more flexible movement performance, while having excellent elasticity and retractability; the tail is designed to be an opening with a diameter smaller than the head; the head and tail are respectively provided with a front clamp 11 and a rear clamp 12, which not only simplifies the installation process of the assembly, but also effectively improves the sealing of the assembly. The clamping design of the front clamp 11 and the rear clamp 12 ensures the firm fixation of the dust cover assembly 1, and enhances its vibration resistance and waterproofness; the dust cover assembly 1 is also intelligently provided with an air sensor inside to detect whether it is leaking, and through the connection with the vehicle system circuit, real-time monitoring and early warning functions are realized. Once the dust cover assembly 1 is detected to be broken and air is leaking, the air sensor will send the steering gear 2 fault information to the vehicle system, so that the driver can know the system status in time and take measures in advance, thereby enhancing the reliability and safety of the steering gear.

[0023] See also Figure 2 The head of the dust cover assembly 1 is clamped with the steering gear 2 and fixed and sealed with a front clamp 11, and the tail is clamped with the steering rod 3 and fixed and sealed with a rear clamp 12, which is extremely convenient for installation and disassembly.

[0024] Working principle: First, the head of the dust cover assembly 1 is designed with a funnel-shaped channel 14, which acts like a funnel and can guide external dust and moisture to flow along the channel instead of directly entering the steering gear 2. A guide baffle 141 is also provided at the end of the funnel-shaped channel. This design effectively prevents water mist from directly contacting metal materials in a humid environment, thereby improving the protective effect. Secondly, the middle part of the dust cover assembly 1 adopts a sandwich structure and is filled with a non-Newtonian fluid 13. During movement, the viscosity and rheological properties of the non-Newtonian fluid play a role, forming a stable damping effect, reducing the friction of the dust cover and extending its life. At the same time, the non-Newtonian fluid has the characteristics of high temperature resistance and anti-aging, which further improves the durability of the dust cover. The tail of the dust cover assembly 1 is designed to have an opening with a diameter smaller than that of the head, which is clamped with the steering tie rod 3 and fixed and sealed with a rear clamp 12. This design not only ensures the close connection between the dust cover and the steering tie rod, but also effectively prevents the penetration of external dust and moisture through the fixed sealing effect of the rear clamp 12. Finally, an air sensor is also set inside the dust cover assembly 1. The sensor can monitor whether the dust cover is leaking in real time by connecting to the vehicle system circuit. Once a leak is detected, the air sensor will send the steering gear 2 fault information to the vehicle system, realizing timely monitoring and warning of the system status. This intelligent detection system helps to detect potential problems in advance, reduce the risk of failure, and thus enhance the reliability and safety of the steering gear system.

[0025] In summary, the dustproof and waterproof enhanced steering machine is provided with a dustproof cover assembly 1, which includes a head, a middle part and a tail. A funnel-shaped channel 14 is designed inside the head, the middle part is a sandwich structure, and the sandwich is filled with a non-Newtonian fluid 13. The tail is designed to be an opening with a diameter smaller than the head. The head of the dustproof cover assembly 1 is clamped with the steering machine 2, fixed and sealed with a front clamp 11, and the tail is clamped with the steering rod 3, fixed and sealed with a rear clamp 12. Firstly, through the design of the funnel-shaped channel 14 of the head, the dustproof cover assembly 1 can more effectively guide and prevent external dust, moisture and other harmful substances from directly entering the interior of the steering machine, thereby improving the protective effect. Secondly, the middle sandwich structure is filled with a non-Newtonian fluid 13. This fluid has very good viscosity and rheological properties, can form a stable damping effect during movement, effectively reduce friction, and extend the life of the dustproof cover. At the same time, it has the characteristics of high temperature resistance and anti-aging, thereby achieving the effect of not easy to be damaged and dustproof and waterproof.

[0026] The dustproof and waterproof enhanced steering gear is equipped with an air sensor to detect whether the dust cover is leaking. When a leak is found, the steering gear fault information is sent to the vehicle system, realizing real-time monitoring and early warning functions, which helps to detect problems in advance and take measures, thereby enhancing the reliability and safety of the steering gear.
