Embodiment 1

[0056] Embodiment 1 and Embodiment 2 both have a three-axle structure, and in embodiments not shown in the figure, the number of vehicle axles may also be two, or more than four. When there are two vehicle axles, there are only front axle and rear axle, no intermediate bridge and balance beam, and the leaf spring balanced suspension mechanism includes a thrust rod assembly and a leaf spring. The two ends of the leaf spring are supported on the front axle and the rear axle, and the middle part is connected to the vehicle frame. When the number of vehicle axles is greater than or equal to four, the vehicle axles include a front axle, a rear axle and at least two intermediate axles arranged between the front axle and the rear axle. A balance beam is hinged on each intermediate bridge, and one end of the leaf spring at the front end among the plurality of leaf springs arranged longitudinally of the vehicle frame is slidably connected to the front axle, and the other end is slidabl...

Abstract

The invention provides a plate spring balancing suspension bracket mechanism and an engineering vehicle provided with the plate spring balancing suspension bracket mechanism. The plate spring balancing suspension bracket mechanism comprises a plurality of vehicle axles and plate springs (1), wherein at least one plate spring (1) is arranged between the adjacent vehicle axles. The two ends of each plate spring (1) are arranged on the two adjacent vehicle axles in a supported mode. The middle portions of the plate springs (1) are connected to a vehicle frame (2). The plate spring balancing suspension bracket mechanism is compact in layout and simple in structure.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a leaf spring balanced suspension mechanism and an engineering vehicle having the same. Background technique [0002] The suspension system is an important part of the car. It elastically connects the frame and the axle to transmit the force and moment acting between the wheel and the frame, and to buffer the shock transmitted from the uneven road to the frame or body. The impact force attenuates the vibration caused by it to ensure that the car can run smoothly. [0003] Large-tonnage truck cranes with five or more axles generally adopt leaf spring suspension. In the design of GM chassis, the chassis usually only has two axes, which can be easily calculated by using the knowledge of mechanics. For vehicles with five axles and above, the axles are generally divided into two groups, front and rear, and the balance suspension is used between the axles of each group ...
