Abstract

The invention discloses a shaft box suspension swing type bogie for a rail wagon. The bogie comprises a wheel set, a shaft box, a side frame, a swing bolster, a side bearing and a foundation brake device, wherein a bearing saddle is arranged between the shaft box and the side frame; central suspension devices are arranged below two ends of the swing bolster; a fixed lever fulcrum seat is arranged on the swing bolster; a rubber spring is arranged between the side frame and the bearing saddle; a spring supporting plate is arranged below the central suspension devices at the two ends of the swing bolster in a connection mode; shaking seats are arranged below two ends of the spring supporting plate and are connected with the side frame through a shaking seat bearing; a falling prevention cylinder is arranged on an outer surface at the rear end of a bearing body of the shaking seat bearing; and a brake pull rod support is arranged on one side of a fulcrum seat body of the fixed lever fulcrum seat. The horizontal performance and the vertical performance of the bogie can be improved, speed increasing requirements of the rail wagon are met, and parts have high connection reliability.

Description

technical field [0001] The invention relates to a railway freight car, in particular to a railway freight car axle box suspension swing type bogie. Background technique [0002] With the continuous advancement of China's railway technology, increasing the load and speed of railway freight cars has become one of the development requirements. my country's railways will gradually realize the separation of passenger and freight lines, and it is even more necessary to develop new types of heavy-duty and express freight cars to further increase freight capacity. One of the keys to heavy load and speed increase of railway freight cars lies in the structure and performance of the freight car bogie. [0003] At present, railway freight car bogies include several types such as swing bogies and axle box suspension bogies. The swing bogie has good lateral dynamic performance, but no obvious advantage in vertical dynamic performance; the axle box suspension bogie wheel has light unspru...
