Abstract

The invention provides a hydraulic motor drive power bogie which comprises a framework assembly. The framework assembly is provided with wheel set assemblies, axle box assemblies, primary suspension systems, secondary suspension systems, braking devices and drive devices. Each drive device comprises a hydraulic motor connected with an installation seat. The installation seats are fixed to the framework assembly. An output shaft of each hydraulic motor is in drive connection with a gear case through a flexible coupling. Each gear case is connected with an axle of the corresponding wheel set assembly and connected with a lifting rod assembly. The lifting rod assemblies are connected to the framework assembly in a suspended manner. The hydraulic motor drive power bogie has the beneficial effects that a hydraulic motor drive manner is adopted, the dead weight of the single bogie can be reduced by about 2 t and 0.85 t; installation space can be greatly saved and vehicle structural design is facilitated; and in addition, the hydraulic motors have the beneficial effects of being stepless in speed change, easy to operate, stable in starting and accelerating and the like.

Description

technical field [0001] The invention relates to a rail vehicle bogie, in particular to a hydraulic motor driven power bogie. Background technique [0002] Rail cars are the main operating equipment for railway construction, line construction, equipment repair, emergency rescue and inspection. Rail cars can be divided into mechanical transmission, hydraulic-mechanical transmission and electric transmission according to the transmission mode. [0003] The mechanical transmission rail car is powered by a diesel engine, and the power transmission is completed through clutches, gearboxes, reversing boxes, drive shafts, axle gearboxes and other components. The mechanical transmission method has low manufacturing cost, low maintenance difficulty and convenient operation, and is widely used in rail cars with power below 270kW. However, the disadvantage of this transmission method is that there are many components, heavy weight, many faults, and a large maintenance workload. [00...
