Description

Technical Field

[0001] The utility model belongs to the technical field related to vehicle accessories, and in particular relates to a balancing device for a front suspension of a tricycle. Background Art

[0002] At present, tricycles have become one of the main means of transportation in rural areas and urban-rural fringe areas. Since the front axle of a tricycle has only one front wheel, the vehicle body will tilt due to uneven road conditions during normal driving, affecting the ride comfort. The vehicle is prone to tilt or even rollover when turning at high speed. As market customers have higher and higher requirements for ride comfort and safety, research on improving the ride comfort and safety of the whole vehicle has received more and more attention. The main reasons for the roll of tricycles are the following two points: due to the structure of the tricycle, the front axle has only one front wheel and is prone to tilt; the fixed connection point of the front fork and the frame is too high from the ground, resulting in poor vehicle driving stability. How to improve the front suspension structure of tricycles and improve the vehicle's roll stability has become an urgent problem to be solved in the current market.

[0003] The existing tricycle balancing mechanism (Announcement No.: CN206734506U) generally has the following problems during use:

[0004] 1. The balancing structure is a rear-mounted structure with poor balancing effect and large space occupation: Poor balancing effect: The rear-mounted balancing structure makes the center of gravity of the vehicle biased to the rear, so when turning or encountering uneven roads, the body is prone to rollover, and the balance is not as stable as the front structure. Large space occupation: The rear-mounted balancing structure usually requires a longer body to accommodate components such as the engine and transmission system, which will increase the overall length of the vehicle and occupy a larger parking and driving space. Maneuverability is affected: Due to the rearward center of gravity, the maneuverability of the tricycle may be affected, especially when driving at high speeds or making emergency turns, which requires greater driving skills and reaction speed to maintain the stability of the vehicle. Not conducive to load-bearing: The design of the rear-mounted balancing structure may limit the vehicle's load-bearing capacity, because the rear-mounted engine and transmission system will occupy part of the load-bearing space, limiting the load-bearing capacity of the rear of the vehicle, so there is an urgent need for a balancing device with better balancing effect and space saving.

[0005] 2. The structure is relatively complex, the production process is complicated, and the production cost is high: Complex process: The design of the balance structure of the tricycle needs to take into account factors such as the stability, handling and safety of the vehicle, so the process involved is relatively complex, including the design and manufacture of the body structure, suspension system, steering system, etc. Diverse components: In order to achieve a good balance effect and handling performance, the balance structure of the tricycle usually requires the use of a variety of different components and materials, such as the transmission system, suspension system, steering system, etc., which increases the types of parts and production processes. High production technology requirements: Due to the complexity of the balance structure of the tricycle, manufacturers need to have a high level of production technology and process, including technical requirements in body welding, parts processing, assembly, etc., which will also increase production costs. High cost: Due to the complex process, diverse components and high production technology requirements, the production cost of the tricycle is relatively high, which will also lead to a high selling price of the final product, which is not conducive to market competition, so there is an urgent need for a simple structure balance device.

[0006] 3. The existing structure will transmit the noise and vibration generated during driving to the upper part: Driving comfort is reduced: Noise and vibration will directly affect the riding experience of drivers and passengers. Continuous noise and vibration will make people feel uncomfortable. Shortened equipment life: Noise and vibration usually mean increased friction between mechanical parts, which will not only generate more heat, but also may cause increased wear of parts. In the long run, this will reduce the service life of the balancing device and its connected parts, and increase the cost of repair and replacement. Reduced operating accuracy: For vehicles or equipment that require precise control, noise and vibration may interfere with the sensor's signal, resulting in reduced control accuracy. This may not only affect driving stability, but also pose a threat to safety. Increased safety hazards: If the noise and vibration are too large, it may affect the driver's attention, making it difficult to accurately judge the road conditions and vehicle status. In an emergency, this may lead to slow response or operational errors, increasing the risk of accidents, so a balancing device with a shock-absorbing and noise-reducing structure is urgently needed.

[0014] The utility model has the following beneficial effects:

[0015] 1. By installing the balancing structure on the front suspension, the following advantages are brought about: Enhanced stability: Placing the balancing device on the front suspension can effectively reduce the roll of the vehicle when turning and improve the stability of the whole vehicle. This is because when turning, the roll of the front part is more likely to cause imbalance, and the setting of the balancing device can suppress this roll and keep the vehicle stable. Improved operability: The balancing device at the front suspension position can make it easier for the driver to control the vehicle because it can more directly affect the steering and balance of the vehicle. Such a design can improve the driver's operating experience and make driving more comfortable and safe. Reduced rollover risk: Three-wheeled vehicles are prone to rollover accidents due to rollover, especially in high-speed turns or unbalanced loads. Setting the balancing device on the front suspension can effectively reduce this risk and improve the safety of the vehicle. Space utilization: The front suspension usually has more space for installing the balancing device, and the installation position is relatively easy to access. This allows designers to arrange the balancing system more flexibly and make it work more effectively. Increased comfort: Increasing the available space in the rear row improves the ride comfort of the vehicle.

[0016] 2. By simplifying the balancing structure, retaining the main balancing rod and connecting rod structure installed on the front suspension, the structural design is simple and compact while ensuring the balancing effect, and brings the following advantages: Simplified structure: Concentrating the balancing structure on the front suspension can greatly simplify the structural design of the entire vehicle, reduce the number of parts and connectors, and reduce the manufacturing difficulty and cost. Compact design: Installing the balancing rod and connecting rod on the front suspension can make the entire balancing structure design more compact, reduce the length and width of the vehicle body, and make the vehicle more flexible and adaptable. Maintaining the balancing effect: Although the balancing structure is simplified, through reasonable design and layout, a good balancing effect can still be maintained to ensure the stability and safety of the vehicle during driving. Reduce costs: Simplifying the balancing structure can reduce the process complexity and the use of parts in the production process, thereby reducing production costs and making the final product more competitive. Easy maintenance: After the structure is simplified, the maintenance and maintenance of the vehicle are relatively simpler, because there are fewer parts, the layout is clearer, and the difficulty of repairing and replacing parts is reduced.

[0017] 3. The balancing bar is covered with a holster. When the balancing bar moves up and down or twists left and right, the holster is subjected to forces in multiple directions and produces torsional deformation. At the same time, it also isolates or reduces the vibration and noise transmitted from the ground tire to the frame through the balancing bar, and brings the following advantages: Excellent isolation and noise reduction effect: The design of the holster can effectively isolate or reduce the vibration and noise transmitted from the ground tire to the frame through the balancing bar. The flexibility and elasticity of the holster can absorb and disperse these vibrations and noise, so that passengers in the cockpit can enjoy a smoother and quieter driving environment. Enhance vehicle stability: The main function of the balancing bar is to maintain the stability of the vehicle, especially when encountering uneven roads or making fast turns during driving. The design of the holster can ensure that the balancing bar can maintain a flexible and stable connection when it moves up and down or twists left and right, thereby effectively improving the vehicle's handling and stability. Extend component life: Since the holster can absorb and disperse vibrations, it reduces the force on the balancing bar and other related components, and reduces their wear caused by long-term impact and friction. Therefore, this design helps to extend the service life of vehicle components and reduce the frequency of repairs and replacements. Improve driving comfort: By isolating or reducing vibration and noise, the design of the stabilizer bar connection leather cover can significantly improve driving comfort. The vibration and noise felt by passengers during driving are reduced, making long-distance driving or riding easier and more enjoyable. BRIEF DESCRIPTION OF THE DRAWINGS
