Abstract

The invention belongs to the technical field of railway wagons, and discloses a swing bolster assembly and a bogie. The swing bolster assembly comprises a swing bolster, a lower center plate, a sand prevention ring and a side bearing; the lower center plate is arranged on the swing bolster, and the side bearings are arranged on the swing bolster and located on the two sides of the lower center plate. The sand prevention ring is arranged on the swing bolster and annularly arranged outside the lower center plate in a sleeving mode, and the sand prevention ring is higher than the lower center plate. According to the swing bolster assembly and the bogie, sand and dust can be effectively prevented from entering the space between the upper center plate and the lower center plate, and the safety of a vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to a bolster composition and a bogie. Background technique [0002] At present, the traditional three-piece bogie bolster is composed of a center plate and a side bearing, which supports the total weight of the car body through the center plate and the side bearing. The upper and lower center plates of the vehicle are of an open rotating and contact structure, and sand and gravel dust can easily enter between the upper and lower center plates. If too much sand and gravel accumulates, the frictional ability of the center plate will be weakened, the function of stabilizing the operation of the vehicle will be lost, and the vehicle will be affected. In extreme cases, it will lead to derailment or subversion of the vehicle, resulting in immeasurable economic losses. SUMMARY OF THE INVENTION [0003] The invention provides a bolster composition and a bogie, which solves t...
