Description

A balance suspension assembly

technical field

The utility model relates to the technical field of balance suspension, in particular to a balance suspension assembly.

Background technique

If two axles (such as the middle and rear axles of a three-axle vehicle) are installed at both ends of the balance bar, and the middle of the balance bar is hinged to the frame, the raising of one axle will make the other Bridge lowered. Moreover, since the two arms of the balance bar are of equal length, the vertical loads on the two axles are equal in any case, and no individual wheels are left in the air. This kind of suspension that can ensure the vertical load of the middle and rear axle wheels is equal is called a balanced suspension.
