Abstract

The invention relates to the technical field of engineering machinery, and discloses an engineering truck and a drive system thereof. The drive system comprises a multi-stage axle and an upper cart engine which are arranged on the engineering truck, at least one hydraulic motor which is connected with a primary axle in a driving manner, and a hydraulic pump which supplies oil to the hydraulic motor, wherein the hydraulic pump draws power from the upper cart engine. In the drive system of the engineering truck provided by the embodiment of the invention, a certain axle is driven by utilizing power of the upper cart engine and a corresponding hydraulic system, or a certain axle is driven by virtue of an independent engine and a corresponding hydraulic system thereof, so that auxiliary drive force is provided to the whole truck when the driving capability of a lower cart engine is deficient or the power transfer capability of the lower cart engine is poor, thus the driving performance of the whole truck is improved, and the requirement on power when the engineering truck is in a server road condition or climbs can be better fulfilled.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an engineering vehicle and its driving system. Background technique [0002] Engineering vehicles are widely used in heavy-duty transportation, building construction, field hoisting, and public services. The construction environment is usually harsh, the road surface is uneven, and the road conditions are poor. Therefore, the driving performance of engineering vehicles has attracted increasing attention. For example, during construction work, wheeled cranes often need to be transferred back and forth between various construction sites, and in the process of driving, they often need to forge mountains and rivers. Therefore, customers are interested in wheeled cranes, especially large-tonnage wheeled cranes. Drive performance requirements are getting higher and higher. [0003] In the prior art, the off-board engine on the engineering vehicle provides power for the a...
