The utility model relates to a power assembly skewing structure which comprises an engine transmission assembly (11), a transmission shaft (12), a parallel gear box (12), a second joint (14) of the transmission shaft and a driving axle (16). The engine transmission assembly (11) of the power assembly skewing structure is installed at the right position, between a first shaft and a second shaft, at the back of a driver zone, an output shaft of the engine transmission assembly (11) is connected with the transmission shaft (12), the transmission shaft (12) is connected with the input end of the parallel gear box (12), the output end of the parallel gear box (12) is connected with the second joint (14) of the transmission shaft, and the parallel gear box (12) is connected with the driving axle (16) through the second joint (14) of the transmission shaft so as to drive tires (15) to rotate. Through the skewing arrangement of a power assembly system, the power assembly skewing structure can obviously guarantee that the capacity of a designed vehicle is reasonably distributed. Meanwhile, an engine is relatively close to the driver zone, the problem that power transmission line harnesses are over long in distribution under the rear mounting or centering condition is solved, and the production cost and the manufacturing time are reduced. The power assembly system is arranged in a skewing mode, so that the engine overload operation can be avoided. The power assembly skewing structure is suitable for ultra-large capacity passenger cars.
