The utility model can be used on three-wheel or four-wheel vehicles with front-mounted frame-like structures.

The specific working principle of the utility model is as follows:

the right rocker arm 6 can rotate by taking the axle center of the rear axle right shaft 15 with the front end fixed in rotation as the axle center while the right wheel 22 obtains power rotation through the right wheel fixing shaft 17, the right bottom fork transmission shaft 16 and the rear axle right shaft 15; since the right swing arm 6 is rotatably connected to the vehicle balance system via the swing arm support connection 14, the rotation range thereof is proportional to the tilting range of the vehicle frame 1 after the whole vehicle is assembled.

The left rocker arm 7 can rotate by taking the axle center of the rear axle left axle 18 with the front end fixed in rotation as the axle center while the left wheel 21 obtains power rotation through the segmented transmission shaft left wheel fixing shaft 20, the left bottom fork transmission shaft 19 and the rear axle left axle 18; since the left rocker 7 is rotatably connected to the vehicle balance system via the rocker support connection 14, its rotational amplitude is proportional to the tilting amplitude of the frame 1 after the entire vehicle has been assembled.

When the vehicle is required to swing and ride, the balance bar locking pin 37 does not extend backwards in the bottom fork balance locking guide pipe 41 and does not prevent the balance bar 26 from rotating, when the vehicle is running or is stationary and does not need to swing, the balance bar locking pin 37 extends backwards by a proper length and is inserted into the balance bar locking hole 40 on the balance bar 26, and as the balance bar locking pin 37 is simultaneously inserted into the bottom fork balance locking guide pipe 41 and the balance bar locking hole 40, the relative position of the balance bar 26 and the bottom fork 23 is locked by the balance bar locking pin 37, and the vehicle cannot swing.

When the left-right swing amplitude of the balance bar 26 reaches a certain degree, bolts arranged in the balance bar right limit seat 38 and the balance bar left limit seat 39 can be propped against two sides below the middle upright post of the bottom fork 23, so that the swing limit effect is realized. The upper limit of the rotation angle of the balance bar 26 can be adjusted by rotationally adjusting the installation depth of the bolts in the right limit seat 38 and the left limit seat 39 of the balance bar, so as to adjust the swaying amplitude of the vehicle.

When the vehicle runs, the frame 1 tilts along with the cornering centrifugal force, and the left wheel 21 and the right wheel 22 simultaneously tilt in a grabbing way, so that the distance between the rocker support connecting pieces 14 on the right rocker 6 and the left rocker 7 and the ground is basically equal, the right rocker support rod 29 and the left rocker support rod 30 can support the balance rod 26 to be basically parallel to the ground, the balance rod 26 and the manned platform longitudinal support 34 are absolutely fixed, so that the manned platform longitudinal support 34 can also be basically parallel to the ground, the top end of the goods shelf rear support rod 33 and the manned platform longitudinal support 34 are movably connected by using the bearing 35, and therefore, the rear support of the manned platform longitudinal support 34 is used for limiting the relative rotation of the manned platform longitudinal support 34 and the goods shelf rear support rod 33; people carrier 36 is secured to balance bar 26 and people carrier longitudinal support 34 and is also maintained substantially parallel to the ground as the vehicle turns and tilts with centrifugal force. The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
