Description

Technical Field

[0001] This invention relates to a two-wheel suspension system for a three-wheeled motorcycle. Background Technology

[0002] Currently, there are two types of three-wheeled motorcycles: one with one wheel in the front and two wheels in the rear; and the other with two wheels in the front and one wheel in the rear. For the suspension systems of current three-wheeled motorcycles with two front wheels, the shock absorbers connected to these wheels are directly fixed to the frame. During cornering, the motorcycle needs to maintain centripetal force, requiring a slight tilt. This can cause the outer wheel to leave the ground, increasing the risk of tipping over. Summary of the Invention

[0003] This invention provides a dual-wheel suspension system for a three-wheeled motorcycle, which ensures that the outer wheel remains in contact with the ground when the vehicle is tilted, preventing the vehicle from tipping over and improving driving safety and stability.

[0010] The present invention has the following beneficial effects: After adopting the above technical solution, the present invention adds a left support roller assembly and a right support roller assembly to the upper end of the left shock absorber and the upper end of the right shock absorber. The left support roller assembly and the right support roller assembly can move within the guide rail connected to the steering handle. In this way, when the vehicle tilts, since the left support roller assembly and the right support roller assembly at the upper connection point can move left and right within the arc-shaped guide rail, the left and right wheels connected to the left and right shock absorbers can swing up and down according to the needs of driving. This ensures that the outer wheel can keep close to the ground when the three-wheeled motorcycle is riding, especially when the vehicle tilts during the turning process, so that the vehicle does not tip over, thus improving the safety and stability of driving. This invention features an adjustable limiting device. When the vehicle needs to move, the adjustable limiting device releases the restriction between the left and right support roller assemblies, allowing them to slide within the arc-shaped track. When the vehicle is parked, the adjustable limiting device restricts the positions of the left and right support roller assemblies, limiting their sliding within the arc-shaped guide rail and ensuring no relative movement between the upper mounting points of the left and right shock absorbers and the arc-shaped guide rail. The guide rail front cover and guide rail rear cover of this invention are rigidly mounted on the vehicle frame, thus ensuring that the left and right wheels connected to the shock absorbers do not wobble when the vehicle is parked.
