The cushioning device can avoid the impact caused by the 'breakdown' of the suspension.

Although the buffer structure solves the problem of large suspension stroke by supplementing the limiting structure above the buffer block, the supplementing limiting structure and the upper suspension move process can generate a fit clearance and generate abnormal sound. Further, the structure in which the dust cover is disposed on the buffer block cannot be realized.
