Description

Motorcycle cushion supporting mechanism and motorcycle thereof Technical Field The invention belongs to the technical field of vehicle engineering, and particularly relates to a motorcycle cushion supporting mechanism and a motorcycle thereof. Background The motorcycle is a common traffic tool driven by a fuel oil power device or an electric power device, is light and flexible, can run rapidly and is widely used for patrol, passenger and cargo transportation and the like by controlling two-wheel or three-wheel vehicles with front wheels steered by handles. The characteristic that it is lighter for four-wheel motor vehicle for it is convenient for control, but also leads to it to jolt the vibrations resistance poorer, and the cushion of motorcycle only supports through the panel beating that sets up both ends around the sub vehicle frame, and especially cross country motorcycle's service environment is generally comparatively complicated, if the vibration range is great in the vehicle driving, can cause the load of sub vehicle frame too big, influences the life of frame. In addition, the front end of the cushion is generally abutted against the fuel tank, and during daily driving, the front end of the cushion is worn with the edge of the fuel tank, so that leather at the front end of the cushion is damaged, and for this purpose, chinese patent CN119370235A discloses a motorcycle which comprises a frame, a body covering part, a walking assembly, a power system and a fuel assembly, wherein the body covering part comprises the cushion, the fuel assembly comprises the fuel tank, the frame comprises a main frame and an auxiliary frame, the fuel tank is basically arranged on the main frame, the cushion is basically arranged on the auxiliary frame, and the cushion is at least partially covered on the fuel tank, the cushion and the fuel tank are arranged to be at least partially overlapped when being observed from the height direction of the motorcycle, the projection size of the overlapped part of the cushion and the fuel tank on the horizontal plane along the height direction is defined as a first area, the projection size of the fuel tank on the horizontal plane along the height direction is defined as a second area, and the ratio between the first area and the second area is more than or equal to 0.12 and less than or equal to 0.18, through the arrangement, so that the auxiliary frame and the auxiliary frame are supported together, the service life of the cushion is prolonged.
