Description
Technical Field

Chinese patent CN201410130637 discloses a hydraulic interconnected torsion-eliminating rear suspension. The suspension is provided with a pair of interconnected cylinders and balance bars on the basis of an independent suspension, so that the interconnection of adjacent wheels on the same side is realized. Such a suspension would be comfortable and load sharing, but would have many mechanical load components and would be of a large longitudinal dimension and not compact enough.
The leaf spring cross type balance suspension disclosed in Chinese patent CN201410818816 is characterized in that leaf springs are mounted in a cross mode on the basis of the leaf spring balance suspension, so that longitudinal space is saved, the wheelbase of a rear axle is more compact, but the trafficability of a vehicle is greatly influenced due to the fact that a part of structure fixing devices of the suspension are too low, and the suspension is also easy to damage.
