Railway maintenance vehicle

Abstract

The invention provides a railway maintenance car, which comprises two groups of power systems arranged in a railway maintenance car main body, wherein each group of power system comprises a diesel engine, a hydraulic transmission gear box connected with an output end of the diesel engine, and a bogie; each bogie comprises wheel sets and skiving boxes used for driving the wheel sets; the skiving boxes are connected to an output shaft of the hydraulic transmission gear box. The railway maintenance car disclosed by the invention is provided with double power systems, thereby achieving the purpose of unit redundancy, the normal running of the car can be guaranteed under the condition that one power system fails, and the appearance of machine broken accidents is avoided to the maximum degree; by the structure that hydraulic transmission is matched with the double power systems, the running speed of the car can reach 160km / h, and the requirements on stationarity and shock resistance when the car runs at a high speed are also met.

Description

technical field [0001] The invention relates to railway vehicle technology, in particular to a railway maintenance vehicle, which belongs to the technical field of vehicle power systems.
