Description

Technical Field

[0001] The utility model relates to the technical field of wheel suspensions, in particular to a terrain-adaptive single-wheel suspension structure for a vehicle. Background Art

[0002] Currently, common vehicles are typically equipped with three or more wheels. When the vehicle travels over uneven roads, shock absorbers are installed on the wheels to reduce vehicle vibration and improve passenger comfort. These absorbers absorb vibrations from the ground. For example, patent publication number "CN1852811A" discloses a rotating wheel with a suspension, which includes a wheel frame, a wheel element rotatable about a horizontal wheel axis, a suspension, and a support arm. One end of the support arm is connected to the wheel frame so that it can rotate about the horizontal support arm axis, and the other end supports the wheel axis at a distance from the support arm axis. The suspension is connected to the support arm at a support arm joint and to the wheel frame at a frame joint. The support arm joint and the frame joint define a straight suspension axis extending through these points. The wheel also has an adjustment mechanism configured to set the distance from the suspension axis to the support arm axis by moving the support arm joint and / or the frame joint along an adjustment track. However, existing shock absorbers can generally only absorb vibrations from the ground in the vertical direction. If a vehicle is traveling on an inclined road, for example, when a motorcyclist bends along the road, the vibration generated by the ground is transmitted upward along the normal direction of the inclined road surface. The direction of the ground vibration is inconsistent with the energy absorption direction of the shock absorber, resulting in unbalanced force on both sides of the shock absorber or wheel, affecting the stability of the vehicle.
