Description

Technical Field

[0001] The present invention relates to the field of suspension devices, and in particular to a synchronously tiltable suspension device for a vehicle. Background Art

[0002] Current three-wheeled (including reverse three-wheeled) and four-wheeled vehicles, including bicycles, scooters, and electric vehicles, have their left and right wheels mounted directly on the main axle. This can cause the vehicle to shake or tilt when traveling on uneven roads, resulting in inadequate stability and safety. Therefore, it is necessary to develop a solution to address this issue. Summary of the Invention

[0003] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a vehicle synchronously tiltable suspension device, which can improve the stability and safety of the vehicle.

[0004] To achieve the above object, the present invention adopts the following technical solutions: The left and right connecting rods are arranged left and right, and the two ends of the left connecting rod are respectively hinged to the left end of the upper chain and the left end of the lower chain, and the two ends of the right connecting rod are respectively hinged to the right end of the upper chain and the right end of the lower chain.

[0005] Preferably, the left swing arm and the right swing arm are both L-shaped.

[0006] Preferably, the left swing arm includes a left cylinder and a left support rod. The left cylinder is sleeved on the left end of the main shaft. The left support rod is welded to the left end of the left cylinder. The tail end of the left support rod is installed and connected to the left wheel. The aforementioned left gear part is welded to the right end of the left cylinder.

[0007] Preferably, the right swing arm includes a right cylinder and a right support rod. The right cylinder is sleeved on the right end of the main shaft, the right support rod is welded to the right end of the right cylinder, the tail end of the right support rod is installed and connected to the right wheel, and the aforementioned right gear part is welded to the left end of the right cylinder.

[0008] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that: The coaxial left and right wheels are synchronously suspended and connected to the main shaft via left and right swing arms. These swing arms are then connected by upper and lower chains, left and right connecting rods, and fixed upper and lower gears to form a linkage mechanism. When the left or right wheel encounters an uneven surface, the distance between them remains constant during their free up and down movement, and the left and right wheels can tilt freely at the same angle, improving vehicle stability and safety during driving, cornering, and braking on uneven or slippery roads.

[0009] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
