Abstract
The invention provides a power system device for a subway grinding vehicle. The power system device for the subway grinding vehicle comprises a diesel engine. The flywheel end of the diesel engine outputs power to drive an electric generator to provide electric power for a grinding operating system, a heat dissipating system, a dust collecting system and a fire extinguishing system of the vehicle to meet the electricity demands. The free end of the diesel engine outputs power to drive an air compressor through one output end of a transfer case to meet the vehicle air damping air using demands, and the other output end of the transfer case drives a first hydraulic motor and a second hydraulic motor through a walking hydraulic pump to achieve the vehicle walking function. According to the power system device, the walking power and the grinding operation power are relatively independent, and therefore the failure rate is low, the maintainability is high, and the practicability and economical performance of the device are improved.
