Description

Technical Field

[0001] The utility model belongs to the technical field related to vehicle accessories, and specifically relates to a novel disc-type steering mechanism of a three-wheeled passenger vehicle. Background Art

[0002] At present, three-wheeled passenger vehicles have become one of the main means of transportation in rural areas and urban-rural fringe areas. The steering mechanisms of existing three-wheeled passenger vehicles include handlebar steering and disc steering. The handlebar steering has a simple structure, a large angle transmission ratio, heavy steering, and poor stability in straight-line driving, which reduces driving safety; the disc steering has a complex structure, and the steering gear and steering connecting rod drive the connecting plate of the front fork to produce left and right steering. The layout occupies a large space, which affects the overall layout and ergonomics of the front suspension, resulting in the disc steering mechanism occupying too much layout space, seriously affecting the driver's riding space, reducing driving comfort, and the steering gear and steering connecting rod are outside the front panel of the cab, which is not conducive to the overall sealing of the vehicle. Now the market urgently needs a disc steering mechanism with a simple structure and light steering, which reduces the overall layout space, increases the driver's riding space, improves the rationality of the ergonomic layout, and improves driving comfort and pleasure.

[0003] The existing electric tricycle steering mechanism (publication number: CN 218839670 U) generally has the following problems during use:

[0004] 1. The disc structure is relatively complicated and occupies a large space, which affects driving and riding: Reduced driving comfort: An oversized steering mechanism may occupy the space originally used for the legroom of passengers or drivers, reducing driving and riding comfort. Increased operational complexity: The complicated structure may make the steering operation more complicated, increase the difficulty of the driver's operation, and thus may affect driving safety. Difficult maintenance: The complicated structure may require more time and cost for maintenance and repair, especially in an emergency, it will be more difficult to quickly solve the problem. Increased vehicle weight: A more complex steering mechanism is usually accompanied by the use of more materials, which may lead to an increase in the weight of the entire vehicle, thereby affecting the vehicle's fuel efficiency and dynamic performance, so there is an urgent need for a disc steering mechanism with a simpler structure.

[0005] 2. When the parts are arranged, they extend outside the cab, affecting the sealing of the whole vehicle: Environmental factors: Poor sealing performance can easily lead to rain, muddy water and other pollutants on the road entering the cab, which will not only make the driving environment uncomfortable, but also damage the electronic equipment and other sensitive components in the car. Noise problem: Poor sealing may make it easier for the noise generated by the road and vehicle operation to enter the cab, affecting the driver's driving concentration and the comfort of the passengers. Reduced thermal efficiency: If the sealing is poor, the efficiency of the air conditioner will be affected, which means that the temperature regulation in the car will be more difficult and energy consumption will be higher in winter or summer. Reduced overall durability of the vehicle: Vehicle components exposed to water and moisture for a long time are prone to rust and corrosion, which will shorten the service life of the vehicle and increase maintenance costs. Safety hazards: Poor sealing may indirectly affect the structural integrity of the vehicle and the normal operation of the safety system, for example, affecting the function of the electronic control unit (ECU), thereby increasing the risk of accidents, so there is an urgent need for a disc steering mechanism that does not affect the sealing of the cab.

This compact layout significantly reduces the space occupied by the steering gear, leaving more space for use inside the vehicle. Improve steering accuracy: Through the steering link, the linear motion of the rack of the steering gear is effectively converted into the left and right swing of the steering rocker arm. This design improves the accuracy and response speed of steering, making driving more precise and stable. Compact structure: The steering column is fixed to the upper part of the steering column bracket by hexagonal bolts, and the distance between the upper and lower crosses at its lower end is short, which further reduces the overall layout space. This makes the steering mechanism of the whole vehicle more compact, which is beneficial to the overall design and performance improvement of the vehicle. Strengthening structural stability: A round tube is welded to the outside of the steering column and welded to the stamped fixed seat. This structure not only reduces the layout space, but also greatly enhances the structural stability of the steering system, making the vehicle safer and more reliable during driving.

[0015] 2. By saving space for each structure setting, the steering structure can be installed in the cab, preventing the parts from extending out and affecting the driving seal, and bringing the following advantages: Improved sealing: Placing the steering structure completely inside the cab helps to improve the sealing of the entire vehicle. This design prevents the parts from extending outside the vehicle, thereby reducing the intrusion of water and dust and protecting the internal components from environmental factors. Reduce noise and vibration: The internally installed steering mechanism can effectively reduce the impact of external noise and road vibration on the cab. This provides a quieter and more comfortable driving environment for the driver and passengers. Increased space inside the vehicle: The compact steering mechanism design saves space, allowing more available space inside the vehicle. This not only improves driving and riding comfort, but also may provide more storage space or a more flexible interior layout. Improved vehicle aesthetics: The hidden steering structure design improves the neatness and aesthetics of the vehicle interior. The hiding of internal mechanical parts also makes the interior of the cab more refined and improves the market competitiveness of the vehicle. More convenient maintenance and servicing: Setting the steering mechanism inside the cab makes daily maintenance and servicing more convenient. Technicians can carry out inspections and repairs without being affected by weather, greatly improving maintenance efficiency and vehicle reliability. BRIEF DESCRIPTION OF THE DRAWINGS
