Independent suspension frame of boosting vehicle

Abstract

The invention discloses an independent suspension frame of a boosting vehicle, which comprises a frame body, a bottom fork, an engine and a cradle which are assembled into a whole, wherein the engine is fixed on the bottom fork, the frame body is articulated with the bottom fork, and the cradle is fixedly connected below the bottom fork. In the whole structure, vibration generated in the running process of the engine can not be directly transferred on the frame body so as to greatly reduce the vibrating sense of the frame body, improve the driving comfort level of a user, prevent the frame body from breaking in the process of long-term vibration and a drive chain of the engine from falling off and effectively improve the use performance of the boosting vehicle.

Description

technical field [0001] The invention relates to a vehicle frame, in particular to an independent suspension vehicle frame of a power-assisted bicycle. Background technique [0002] Existing mopeds (mainly chain-driven), including motorcycles, have their motors directly fixed on the vehicle frame, the flat forks connected to the middle of the vehicle frame are hinged with the vehicle frame, and the cradle is directly fixed on the vehicle frame. During the use of the moped with this structure, because the engine rotates at a high speed, the vibration generated is directly transmitted to the frame, which is easy to cause the frame body to break, and the user's hands and feet are directly in contact with the frame, and the hands and feet vibrate. It is easy to produce numbness when driving, which reduces the comfort of the moped. At the same time, because the engine and the fork do not remain relatively stationary during the movement, it is easy to cause the rotating chain on th...

Problems solved by technology

During the use of the moped with this structure, because the engine rotates at a high speed, the vibration generated is directly transmitted to the frame, which is easy to cause the frame body to break, and the user's hands and feet are directly in contact with the frame, and the hands and feet vibrate. It is easy to produce numbness when driving, which reduces the comfort of the moped. At the same time, because the engine and the fork are not kept relatively still during the movement, it is easy to cause the rotating chain on the engine to fall off when the road is bumpy.
