摘要： Disclosed is an independent suspension system, comprising: two suspension cylinders (1) which are respectively arranged between wheel edges (21) of wheels at two sides and a frame (8); and a steering mechanism (3) which is used for driving the steering of the wheels at the two sides under the drive of a steering cylinder. The independent suspension system also comprises two swing links (4) which are arranged corresponding to the wheels at the two sides, wherein the end portion of each swing link (4) at one side is hinged to the wheel edge (21) of the wheel at the corresponding side via a spherical hinge; and the end portion thereof at the other side is respectively hinged to a fixed component which is fixed below a main reducer (5) in forward and backward directions via two spherical hinges. Also disclosed is a crane having the independent suspension system. By means of the improvement of the structure, the alignment of tires mounted at the wheel edges is achieved, thereby ensuring that the movement of the tires conforms to the design requirements when the crane is travelling, thereby avoiding destructive effects which the suspension cylinders may have, so that the mutually independent movement of the wheels at the left side and the right side can be reliably achieved.

摘要： The present disclosure relates to the technical field of construction vehicles. In particular, the present disclosure relates to a drive axle assembly and a construction vehicle. The drive axle assembly for a construction vehicle provided by the present disclosure comprises a left wheel, a right wheel, a disconnected axle, a main reducer, and a transfer case, wherein the main reducer is drivingly connected with the left wheel and the right wheel through the disconnected axle, the main reducer is drivingly connected with the transfer case and a housing of the main reducer is connected with a housing of the transfer case, and the main reducer is fixedly connected with a frame of the construction vehicle. The present disclosure integrates the transfer case and the main reducer as an integral structure based on the disconnected axle, which not only can save the arrangement space and accomplish more driving schemes, but also has smaller unsprung mass, capable of reducing the impact on the whole vehicle and improving the manipulating stability of the whole vehicle.
