Abstract

The invention provides a transfer case, a chassis assembly and a crane, and relates to the field of engineering machineries. The transfer case comprises a transfer case body, and a first power take-off mechanism, a second power take-off mechanism and an interlocking mechanism which are arranged on the transfer case body; the transfer case body comprises an input end, a loading output end and a chassis output end; the first power take-off mechanism is used for connecting the loading output end with the input end, and the first power take-off mechanism comprises a first power take-off shaft; thesecond power take-off mechanism is used for connecting the output end and the input end of the chassis and comprises a second power take-off shaft; and the interlocking mechanism is used for limitingthe first power take-off shaft and the second power take-off shaft and executing power take-off action at the same time, the interlocking mechanism comprises an interlocking piece, the interlocking piece is arranged in the transfer case body in a sliding mode, and the interlocking piece comprises a first interlocking end and a second interlocking end which are oppositely arranged. According to the transfer case provided by the invention, the safety problem caused by an error of a neutral feedback signal that a neutral gear is engaged in the transfer case due to a fault of the transfer case iseffectively avoided, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a transfer case, a chassis assembly and a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Most of the large cranes are equipped with two sets of power systems, the two sets of power systems independently output power, and the two sets of power systems provide power for the upper body and the chassis of the crane respectively. [0003] In the prior art, in order to save the manufacturing cost of a set of power system, a power transfer case is provided on the chassis, which is used to transfer the power output by an engine in the power system on the chassis through the transfer case. The ground is output to the top of the crane for hoisting or the chassis for driving. During normal hoisting operations, first drive the crane to the hoisting ope...
