Abstract

The invention relates to a variable-rigidity leaf spring crossed type balanced suspension. The variable-rigidity balanced suspension comprises a front axle, a rear axle, a front leaf spring, a rear leaf spring, a frame, an absorber, U-shaped bolts, a front spring lifting lug, a balance arm support and a rear spring lifting lug. The variable-rigidity leaf spring crossed type balanced suspension is characterized by further comprising a composite leaf spring type balance arm; the composite leaf spring type balance arm comprises a main leaf spring, an assistant leaf spring and a leaf spring clamp; the assistant leaf spring is arranged on the main leaf spring though the leaf spring clamp; the leaf spring clamp is hinged to the balance arm support. The variable-rigidity leaf spring crossed type balanced suspension is applied to a multi-axle vehicle, eccentric wear of tyres is decreased under the condition that axle base is decreased as much as possible, stress of the frame is more uniform, and self weight is reduced; meanwhile, the design flexibility is improved due to the fact that the rigidity of the balance arm is variable, and the ride comfort of the vehicle under different loads is improved.

Description

technical field [0001] The invention relates to the suspension field of multi-axle vehicles, in particular to a variable-stiffness plate spring cross-type balance suspension, which is suitable for cargo vehicles and engineering vehicles with heavy load and multi-axle support. Background technique [0002] Non-independent leaf spring suspension is the preferred solution for the rear suspension of most trucks and engineering vehicles. It has the advantages of simple structure, low manufacturing cost, easy maintenance, small space occupation, and can reduce the height of the vehicle floor. It is used in commercial vehicles. It is widely used; however, due to the large longitudinal dimension required by the leaf spring, the rear suspension of multi-axle trucks and engineering vehicles mostly adopts a four-link balanced suspension, that is, the two ends of the leaf spring are supported in the middle and rear. On the axle housing, it is equivalent to an equal arm balance bar, whic...
