Description

Technical Field

[0001] This utility model relates to the field of ultra-low-profile front suspension technology, and in particular to an ultra-low-profile front wheel frame device. Background Technology

[0002] The ultra-low front suspension system is an advanced automotive suspension technology designed to enhance vehicle dynamics and driving experience. With the increasing demands for safety and comfort in modern automobiles, traditional suspension systems have proven limited in their performance at high speeds or in extreme road conditions. To address these challenges, the ultra-low front suspension system was developed. Its core idea is to lower the suspension height, thereby lowering the vehicle's center of gravity and improving stability. Its innovation lies in its modular design and intelligent adjustment functions, which dynamically optimize damping response and steering performance based on real-time road conditions, ensuring balance during driving. The ultra-low front suspension system not only improves vehicle stability and handling in corners but also significantly reduces the transmission of road vibrations, providing passengers with a more comfortable ride. Furthermore, its advanced design and functionality make it a significant breakthrough in modern automotive suspension technology, driving the future development of intelligent and comfortable vehicles.

[0003] Ultra-low front suspension systems are widely used in modern automobiles due to their optimization of the vehicle's center of gravity and handling. However, when encountering potholes, this system still has certain limitations: the front suspension design cannot fully compensate for the differences in tire-road contact points, resulting in noticeable bumps. This phenomenon is mainly caused by the combined effects of the front suspension geometry, spring elasticity, and changes in tire grip. Bumps not only reduce passenger comfort but can also affect driver judgment and handling stability. Therefore, solving the bump problem of ultra-low front suspension systems when driving through potholes remains an important direction in current automotive technology research.

[0004] In response to this technical problem, this application proposes an ultra-low-profile front wheel frame device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-8 This utility model provides an embodiment of an ultra-low-profile front wheel frame device, including a wheel side plate 5. Rolling wheel axles 4 are fitted at both ends of the inner wall of the wheel side plate 5. Wheel frames 3 are installed at both ends of the outer wall of the wheel side plate 5. Sliding bushings 9 are rotatably connected to the middle of the inner wall of the wheel side plate 5 and the left and right ends of the front end of the wheel frame 3. A central wheel axle 2 is installed on the inner wall of the sliding bushing 9 at the wheel side plate 5. Elastic pins 1 are fitted at both ends of the sliding bushing 9 and the rolling wheel axle 4. The outer walls of the elastic pins 1 are respectively installed on the inner walls of the wheel side plate 5 and the wheel frame 3. Rolling wheels 7 are fitted on the outer walls of the rolling wheel axles 4. The interior of the rolling wheels 7 is filled with carbon fiber composite material, and a rubber layer is provided on the outer side of the rolling wheels 7. Bearings 6 are fixedly connected at both ends of the rolling wheels 7. The inner walls of the bearings 6 are installed on the outer walls of the rolling wheel axles 4. A central wheel 8 is fitted on the outer wall of the central wheel axle 2. The inner side of the central wheel 8 is filled with glass fiber reinforced foam, and a polyurethane coating is provided on the outer side of the central wheel 8. A carbon fiber mesh composite coating is provided on the outer side of the wheel frame 3, and an epoxy resin coating is provided on the outer side of the wheel side plate 5.

[0028] Specifically, this device achieves smooth vehicle passage and efficient maintenance under complex road conditions through innovative structural design and material combination. Its core structure consists of a wheel side plate 5 (coated with an epoxy resin layer on the outside to enhance corrosion resistance) and a wheel frame 3 (covered with a carbon fiber mesh composite coating to enhance structural strength). Two sets of rolling wheel axles 4 are fixed to the front and rear ends of the inner wall of the wheel side plate 5 via elastic pins 1. Rolling wheels 7 (internally filled with carbon fiber composite material for lightweighting, and covered with a wear-resistant rubber layer) are fitted to the axle ends, working in conjunction with precision bearings 6 to achieve low-friction rotation, forming the main load-bearing wheel system. The wheel frame 3 adopts a triangular three-hole structure, forming a four-bar linkage lifting mechanism with the wheel side plate 5 via sliding bushings 9. Dynamic adjustment of the wheel assembly height is achieved through geometric deformation, realizing ultra-low-profile operation.

[0029] In the dynamic adjustment system, the central wheel axle 2 extends laterally through the middle of the wheel side plate 5 via the sliding bushing 9. Its external central wheel 8 uses a glass fiber reinforced foam core (coated with a polyurethane coating to enhance grip), forming a three-level support system with the main wheel system. When a road surface depression occurs, the main wheel system, due to the elastic deformation of the wheel frame 3, triggers the linkage mechanism to raise and lower, allowing the central wheel 8 to quickly fill the 20-50mm vertical gap. When encountering a raised obstacle, the elastic pin 1 allows the rolling wheel axle 4 and the central wheel axle 2 to rotate ±15° for compensation, which, combined with the axial displacement of the sliding bushing 9, buffers the impact. This dual-mode compensation mechanism (rotational obstacle avoidance of the rolling wheel 7 and filling support of the central wheel 8) reduces vehicle vibration amplitude by more than 60%.

[0030] In terms of maintainability design, all shaft systems (roller shaft 4, center shaft 2) are tool-free to be disassembled and assembled via elastic pins 1. Roller 7 and bearing 6 use an interference fit to ensure coaxiality, while center shaft 8 and sliding bushing 9 maintain a 0.5mm clearance to accommodate deformation. Experimental data shows that the device maintains a shaft misalignment accuracy within 0.05mm after 100,000 impact tests, and the carbon fiber mesh composite coating of wheel frame 3 increases the structural fatigue life by 3 times. Through modular assembly design, the replacement time for a single wheel set can be controlled within 5 minutes, significantly better than traditional welded wheel frame structures.

[0031] Working principle: The roller 7 can rotate through the assembly of the roller axle 4 and bearing 6 inside the wheel frame 3, allowing it to move smoothly. The wheel frame 3 uses a triangular three-hole design and works with the wheel side plate 5 to form a linkage mechanism for lifting and lowering, achieving ultra-low positioning. When encountering uneven conditions, the middle wheel 8 can fill potholes in the road surface, allowing the vehicle to pass smoothly. The roller 7 uses bearing 6 to reduce friction during rotation, and the middle wheel 8 uses sliding bushing 9. Together, they can compensate for bumps on uneven ground, making the fork surface stable. Furthermore, when the roller axle 4 and the middle wheel axle 2 are assembled with the wheel frame 3 and wheel side plate 5, they are installed by rotating the round shaft through elastic pin 1, which facilitates maintenance and replacement and provides good fixation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
