Independent suspension system and crane with the independent suspension system

Abstract

The invention discloses an independent suspension system, in which two suspension oil cylinders are arranged respectively between the wheel edges of the wheels on both sides and the vehicle frame; the steering mechanism drives the wheels on both sides to turn; The rod connection ends of the V"-shaped swing rod are respectively hinged with the upper part of the wheel edge of the corresponding side wheel through ball hinges, and the separated ends of the rod are hinged with the fixed member fixed under the frame along the front and rear direction through ball hinges; The rod connection ends of the lower "V"-shaped swing rods are respectively hinged with the lower part of the wheel edge of the corresponding side wheel through the ball hinge, and the two ends of the rod are separated from the fixed member fixed under the frame through the ball hinge along the front and rear direction. hinged. The invention can avoid the possible destructive influence of the suspension oil cylinder, can reliably realize the independent movement of the left and right wheels, fully utilizes the adhesion conditions of the road surface, and improves the control stability of the whole machine. On this basis, the present invention also provides a crane with the independent suspension system.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an independent suspension system and a crane with the independent suspension system. Background technique [0002] As we all know, for large heavy-duty all-terrain construction machinery, the driving stability of its chassis directly affects the operation performance of the whole machine. In addition to the chassis power system, its suspension system is a key factor affecting driving stability. [0003] Taking the chassis suspension system of an all-terrain crane as an example, traditional rigid bridges are commonly used. According to the structural characteristics of the guiding mechanism, it is mainly divided into two categories: non-independent suspension and independent suspension; among them, the left and right wheels of the non-independent suspension are mounted on an integral rigid shaft or the axle housing of the non-disconnected drive axle. The independen...

Problems solved by technology

[0007] First of all, the side of the guide sleeve of the suspension cylinder is connected to the frame, and the lower end of the piston rod is connected to the wheel edge. The weight of the vehicle body and the reaction force applied to the tire by the ground all act on the suspension cylinder, which has poor force characteristics and affects the service life.

[0008] Secondly, the entire steering mechanism is installed above the main reducer, which cannot effectively control the minimum clearance between the main reducer and the ground, resulting in poor trafficability.
